HEAT PUMPS ARE ANOTHER EXPENSIVE SCAM TO FREEZE YOU OUT

[@bengteklund1576]

I saved 3000 dollars when I installed a heat pump. So can you

[@StofStuiver]

Good story m8. And true. Its even worse though. There is no global warming other than recovery from little ice age and CO2 does not affect temperature. Lots of studies found no correlation and worse again even; CO2 is THE life giving substance on earth. Plants need it to grow and the current levels of CO2 are too low, bc there is continuous binding (by tiny lifeforms) into rock. Thats where the vast majority of CO2 is now. If anything, using fossil fuels is needed and there is plenty of it. Then the question remains why they push this nonsense. I think it is 2 fold: One, for the people in power to gain power and TWO, because of the principle that mankind has always tried to free people from labor by producing more efficiently. This has brought us to the situation where half the jobs in the west are non producing/ non functional jobs. So they want to push new things all the time, to employ more people and keep money 'rolling'. Our currencies (none of which are actual money) are going down as the west is crumbling financially and economically. All this creates new tech, new products, new jobs (as you also state) and postpones the inevitable for a bit. But that wont last. One of those fields is solar and wind energy, but that only works, bc they keep increasing prices and have most of that stuff made in China, with fossil fuels. Thats all trickery. Energtically there is no gain of energy from solar and wind, as it is used now. It depends somewhat on the lifespan, which is pretty certain at this time for windturbines and for solar... probably not much more than stated. Also the efficiency of solar cell panels gradually goes down. Same as for hear pumps, but in a different way. Heat pump sounds nice, but again, you have to add all cost to make an energetic balance and i dont think its going to be beneficial. The entire circus is probably going to come crash down soon.

these prices are just bonkers for air to air pumps.. what sieze house you got? My grandparent have a 1960's suburban house, used to have direct electricity heating, they installed a air to air heatpump for less then 3000 euros, covering 90% of their heating needs over the year. Their house walls have less then 10cm of insulation, added insulation to the attic for another 2-3000 euros and their heating costs have gone down with 70% that heat pump payed itself off in a few years. Air to air pumps for a 100 sqm house should not cost that much, and in the cases you need bigger pump.. here people tend to buy a second or even third pump for basement or if they got more floors. If your house consist of many rooms, air to air is also less effective. If you got a water radiator system and your house is big or many rooms, air to water is the way to go, or even better geothermal, but more costly investment.

Top rant Roger. But please base your rant on the correct numbers. A COP of 1 or 2 is very very bad (did I say that's is very bad COP). You might get a COP of 1 at -20C. The average COP (or better Seasonal COP (SCOP), is around 3.4 to 4. So even at 0C, the COP of a good heat pump is > 3. Furthermore you are talking about Air-Water heat pumps. You forgot (the more expensive) Water-Water heatpump where the COP is quite stable because the energie is taken from the earth which is quite stable, even is it is < -10C. The heat pump is certainly not a new technologie, it might be new technologie for the UK and is perfectly capable of heating a normally build house. Heat pumps rely on low temp radiators or floor heating and are doing a great job. But you need to understand how it works. A heat pump is the last thing you install in your house, after you got rid of the draft and the uninsulated floor, walls and most important the roof. Your rant should be about the uninformed installer (including yourself I'm afraid). Please get your fact right. p.s. By telling your audience that some people may say things work perfectly, but those are exceptions, you stop any good discussion before it even started, a bad idea.

Disconcerting that you've got 19 upvotes so far. Quite a few people have clearly bought the hype, and are in for a nasty shock when they go ahead and install a heat pump. Air source heat pumps are expensive as it is, ground source heat pumps cost even more, and will be way out of most people's price range. Most UK housing stock is too draughty for heat pumps to work properly. Our houses actually have air bricks built into them to let outside air in and ensure there's adequate ventilation. Houses designed for heat pumps are completely draught proofed and don't have any built in ventilation, instead they use something called MVHR (mechanical ventilation with heat recovery) to exchange interior and external air without much heat loss. It's not feasible to draught proof existing housing stock to the level required for heat pumps to work efficiently. That's why people who have them installed are complaining of cold houses and large electricity bills. The COP of a heat pump depends on the outside temperature. Their COP drops substantially below 0C, and below about -10C most of them shut off altogether and switch to resistive heating (COP of 1, the heat you get out is the same as the electricity you put in). When it's colder you also need more heat of course, so what this means is that the electricity demand of these things spikes dramatically in cold weather. By what could easily be a factor of 10. Very cold weather doesn't happen that often in the UK so it might not seem like that big a deal, but if millions of households have converted to these things it's going to crash the grid. We have very little spare generating capacity as it is, there quite simply isn't enough spare capacity to support millions of air source heat pumps (especially if their demand climbs to 10x normal due to very cold weather). It'll be like the blackouts in Texas, except a regular occurrence every time there's cold weather. Vulnerable people will die, and housing stock will be ruined by pipe bursts. It's an insane policy, especially since most of our electricity is generated from gas with an efficiency of only about 50 percent, when modern gas boilers have an efficiency greater than 90 percent.

[@mikehenson819]

I live in Tennessee. I designed and built my house 31 years ago as a passive solar using a heat pump. Overall I’ve been very happy with the results. During the summer the unit runs much more than in the winter. So it actually cost us more to cool than to heat. The difference is about half as much to heat due to how well the sun heats the house, providing it’s sunny out. But I have gas logs in the fireplace, and they actually can hear the house nicely.

I have been fitting Heat Pumps for 25 years, and yes they have there limitations. A lot of what has been said in this video is correct, however if designed and selected properly a Heat Pump will work and be efficient. I have had to rectify many systems due to poor design and the end user has been poorly advised. We are fitting loads of Air to Air Heat Pumps ( Air Conditioning units ) that also cool for £1200. In some cases they are the sole heat source, others the existing heating remains and is used as a top up. As with most things there is a middle ground ie not all Heat Pumps are bad and not all are good. People out there need to apply there own scrutiny and common sense when listening to sales people.

I have two air to air heat pumps fitted, an older Daikin and a newer Mitsubishi Ecocore. I also have undertile heating fitted throughout most of the house (the electric mat style not water pipes). When I bought the property eleven years ago the Daikin was the sole heat source for the property, and while it heated the air in the lounge and dining room, once you opened the door to the hall to get heat down to the bedrooms the lounge became quite cool. The second problem was that when you opened either of the doors (there are two ranchsliders in the lounge), all the heat seemed to disappear out the door, a problem when you have a cat. The other issues were the noise and dust. Now the undertile heating, rather like a radiator provides background heat that is silent and doesn't leave the house when the door is opened (no to the same extent at least), and heats the whole property. We rarely use the heat pump for heating, probably a couple of times a year only, but regularly run both for cooling, having one in the bedroom is the best thing we have done, and the Ecocore is quiet enough that you can sleep with it on. If I was still in the UK I would be maintaining my gas central heating but would look at adding a heatpump for the A/C element.

[@martinasher8705]

I'm sure you are right but as Roger said if your house is super insulated then a heat pump will work fine but we live in the real world and unless we are going to knock down all the older houses and build new ones at a time when the building trade cant keep up with the current demand its not going to happen.

[@SoulmongerV2]

@@martinasher8705 Walls are rarely the issue. As long as they're brick or stone and thick enough they will hold heat reasonably well. Majority of heat losses come from poorly insulated roofs/attics and old doors and windows. If you fix those your heating bills will reduce significantly. Whether it's worth the investment depends on the expected cost return of the initial investment but the prices of electricity/fuel will only go up, the insulation will reduce your bills for years to come.

Person from Scandinavia here. We have had heat pumps as the de-facto standard heating option for 10-15 years in Scandinavia, which means that almost all houses nowdays run on heat pumps. People are happy with them, and they work well and are cost efficient. So I don’t undestand the argument with low temperatures and bad efficiency in the UK - we only have such a problem during the coldest winter days that never happen in the UK . With respect to the tap water, it is just simply a imagenative problem that you can’t combine energy efficient tap water, comfort and legionella-safe. Come visit us here in Scandinavia and you’ll see. I fully acknowledge that British houses are not well insulated, but that means that A) houses shall be insulated B) the heat pump needs to be of greater dimension.

I am curious what type of system is connected to your Heat pump..? Is it water.. ie underfloor piping or Radiators.. or.. Air warming like the American 'Central air' with lots of box ducting. Your country (assuming Sweden) generally has an overall yearly lower temperature than us in the UK and you have designed and build property (and indeed your infrastructure) to cope with it.. We are not so organised here and any extreme weather tends to flummox us and everything shuts down.. Also, UK houses dont tend to have suitable places to mount the main pump box and the fan can be surprisingly noisy.

I’m a heating engineer and I would never install the air source heat pump in an old house doesn’t make financial sense… It only works in brand new developments with high levels of insulation.. but once again costs tend to spiral out of control because in these new efficient homes you need to start to run some form of ventilation system with heat recovery.. homes need to be ventilated to ensure you do not have issues in the future with mould or damp areas in your house due to the home being well insulated. So to be honest you’re better off trying to spend that money in increasing the energy efficiency of the fabric of the building..

I'm in a brand new home right now. Its great in the winter but flippin hot right now. I might need air conditioning.

[@RickGuitarPRS]

This technology is unfit for purpose for most homes in the UK. To adequately insulate my home would mean removing external walls to install expensive insulating materials and then rebuild the walls. Pensioners obviously have minimal income and could not afford to do this. As this video states there is very little heat in the air when heating is required and it will take hours to raise the temperature in the home. The immersion heater will be on most of the time to heat the hot water (which, at the inlet, is at it's lowest temperature in the Winter) so it will require electricity (higher running cost). Someone is making a lot of money introducing these Policies. Money is why this is being forced on us.

[@nigelbarratt6825]

Couldn't agree more. I've been in the commercial heating, ventilation and air conditioning business for over 30 years and it's a con. All refrigeration systems like this do is move heat from one place to another. Like a fridge in the kitchen, air conditioning takes heat from inside and loses it outside, heat pumps also work the other way round, taking heat from the outside and putting it inside. Aircon will work great in the winter as you're losing heat into cold outside air, but that's when you don't need it anyway. Similarly heat pumps work best in the summer as you're losing cold into hot outside air, when again you don't need it. When you do need it, it's hopelessly inefficient. Radiator temperatures are warm at best in the winter, not like your nice hot gas boiler system at almost double the water flow temperature. Hydrogen gas boilers make far more sense with zero emissions.

[@neilanderson2374]

Mine works just fine. Admittedly they need more thought when designing a new system than a fossil fuel boiler. But we have to get away from fossil fuels. Hydrogen is even more inefficient as you need to include wastage in creating it from electricity and transporting it. There are 7.2 million Heatpumps installed in France at the last count. Those old Chateaus bought up by the Brits are pretty drafty.

[@LOOKINVERTED]

I agree hydrogen sounds far more promising and realistic. Of course, same argument as with cars, the "vs electric" debate - which themselves aren't the silver bullet people think they are, far from it and are a bit of a con quite frankly. They've spent most of their carbon credits just in their creation, not to mention batteries, as we well know lose their efficiency too and need replaced and I doubt there's enough rare minerals in existence to meet the needs of everyone once-over given what we're potentially planning, let alone consistent replacements - they barely get recycled now either due to the complex and costly nature of doing so. We've all heard about the mountains of e-waste and it's just sitting there so it must be costly to recycle. So as I understand it, the issue with obtaining hydrogen is extracting it from the water in the first place, right? Which itself requires... heat (invariably a fossil fuel). However, if we can find a practical method of splitting the H from the O with a respectable return in efficiency then we're far more likely to actually develop a commodity for heating homes on a national scale. Heat pumps powered by wind or solar (that's what they imagine) is pie in the sky, unless of course we reconsider nuclear (conventional fission). But the greenie lunatics don't like nuclear. Maybe fusion but that's 20 years off, again, and maybe again.

Re electric cars (off topic I know), a petrol station with 12 pumps and 5 minutes per fill up/payment can in theory serve 144 people per hour flat out. A site with 12 rapid charging points can serve an average of about 15 per hour, provided they only want about 80% charge each. Bad enough until you look at the electrical load of 12 rapid chargers - many times more amps than 12 pumps and almost certainly more than the site's electrical supply can support, so you'd need a bigger supply...... then you'd have more loading on the national grid and substations.... bigger required again, then you'd need the extra generating capacity which we haven't got (especially on a windless dull day!) ..... and that's without the people who can't charge at home as they live in a flat or a terraced house with no drive.

Just not sure on the type of return you'd get using that method? Speculating here but running a windmill or solar (for instance) to create the electrical power, surely that wouldn't sufficiently convert hydrogen in suitable quantities for such an industrial undertaking? Nuclear energy yes, but that type of output is obviously a far cry from using these supposed renewable technologies to do the same. Interesting debate none the less.

[@reneverstraeten]

That heat jacket is really a good idea. I work in my house with a heated chair with room temperatures at about 15 degrees. Sometimes my fingers get stiff because of the cold though, and I cannot play guitar or type quickly. The greenest solution for your house is always isolation and elimination of heat losses. You can lend or buy a heat camera and make a heat picture of your house when it is cold to get the places where you prioritize your efforts in this. You are completely right about heat pumps, when the outside temperature drops the gain in efficiency of heat pumping compared to an direct electric resistance heater becomes negligible. And power from coal and gas from your grid supplier is made wide 40% efficiency so when coal or gas is burned you need at least an effiency factor of 2.5 to have an ecological gain , that is not in deep winter temperatures. Where all the electric power would come from in a huge winter is not yet solved, as in pure winter there is little sun and sometimes even wind can not deliver when the blades on the sea or land wind parks are frozen with ice deposits. Just one "terrible"winter will change the minds of the greenies that think this is a solution. The damage of a power outage in such a winter water systems will be huge all over the projects that use this technology,:frozen houses, sewer systems, leaking pipes,cracks in the wall, with additional poor people frozen to death inside their home ,or sick because of the cold. It is not even a matter of economics , that can be for personal decision-making be covered up by subsidies, it is pure technical energy input -output calculation that makes this a very bad idea, as the investment in energy and raw materials could be nearly as high or bigger than the gain. To begin with, CO2 is not the devil's gas, it is on the contrary, an essential food for plants that is good for the earth and that have in geological past times always fluctuated and that is now very scare at 1 in 2500 molecuels in the air. CO2 as driver of temperature change is fake science. So the whole presumption of the gov on CO2 is just BS to begin with. The gov claims that it is science , but it is croony science, only there for opportunistic causes: modern Lysenko-ism. This heat pump plan belongs in the waste bucket as many more "green" plans like electric cars, bio energy, abandonment of nuclear energy, nitrogen fertilization limits. The EU is still on this path until the European economy is not there anymore. Germany will topple over and will be poor and hungry the next generation as they were the most fanatic in green policies.

Nice and lovely and warm in the house. Cost of gas in UK about 1/4 of Electricity in UK. Yes I can see why installing what you call an air heat pump (which in fact is an air to water heat pump) is not a great idea. Recently in Australia I installed a mini split Fujitsu. It uses DC inverter technology and even flat out it is very quiet both inside and outside. Coat of unit plus install was $3000 Australian dollars which is about 1500 Pounds UK. Ok first why heat the whole house ? When I was a lad in the UK you heated the house with a coal fired Kitchen range. Sure only two rooms would be warm and the bedrooms would be cold. So first don't try and heat the whole house. Second you are talking about air to water heat pumps . They involve much more complex copper pipe work and radiators. So why not install say two or 3 Mini splits Air to Air heat pumps. These new DC inverter units ramp up and down automatically also they have infra red detectors, so they go into low mode when people are not in the room. One thing we have done in Australia and I bet this happens in the UK is that all energy companies are charging the same price per MWhr no matter what their energy source is. Oh of course one great thing about the Mini Splits is they will cool very effectively and as you guys in the UK have found out you are now getting very hot summers.

If your house is poorly insulated or anything else then any form of heating will suck, certainly if you are going for less that comfort the low grade heat with especially non-ducted systems can make for a wind-chill effect, but the answer is to run it higher, insulate better or use a ducted heat-pump not high-wall.

Yeah, I'm just to the west of you in SE PA. You have the ideal situation for a HP. Your source temp is 55 and output temp is about 85-90 deg F. or about a 35 deg rise. These HP's in the UK are air to water, so about 35 deg F outside air temp up to 120 deg F is about an 85 deg rise. This makes the compressor operate at a much higher pressure ratio and really hurts the efficiency. Having to heat water which then heats the air has a big impact on performance.

Last November our gas bill went from 350 euro per month to 850 euro per month all thanks to Ukraine war. We live in Austria. We threw the gas out and put in a 9kw heat pump. Cost complete 24,500 euro the government gave us 17,500 euro back. We have run out for our underfloor heating and hot water now for over a year. We have underfloor heating. The extra power that is getting used comes to 70 euro per month. Two weeks ago it was -10deg outside the house was a happy 22 Deg. The average consumption of power for this week was 70kwh at .24cents per kWh or 16.80 euro. The savings from gas has worked out at 6,000 euro pr year. For heating and hot water. Yes our old system was old and not at all economic. We have a 300 ltr hot water cylinder which gets heated once per day happily to 65deg. Hence after one and a half years we will get our cost of 7,000 euro back. If the formulas are put into the heat pump computer by someone that knows their trade like we were able to get. We get nearly 4 times the return of energy than the electricity we put in The house has 120 SQM of underfloor heating which holds enough water to act as a buffer tank. Once the floor has reached 25 Deg the consumption of energy needed to maintain this temperature drops down to around 10kwh per day or less. The main tension is because when the house got built the underfloor heating pipes are intact in the middle of the cement floor not at the bottom of it. Turning the cement slab into a far better heat buffer. The only concern I have is how long will it really last with all the electronics in both the inside and outside units. I'm told due to it being a top brand we should get at least 15 years without problems. Also the unit has been installed correctly with the outside unit sitting 14 meters away from the house in our garden. With the pipes and cables put in a 1 meter trench to stop any freezing problems in winter. As the ground will hold the heat once it's under 700mm as above that the soil may freeze in winter. The outside unit is bolted to cement feet which go down also one meter with a two meter deep soke hole filled with large stones under the unit this let's the temperature of the ground stop the outside unit freezing and the condensation water from the unit can doke away without freezing and having to chip it out from under the unit in winter. Or putting in heating under the unit. So to hear this person say that the cost to run a heat pump is far more than gas. I have to disagree. Even if the gas prices come back down to pre Ukraine war prices. 70 euro per month is still way better than the 350 we were paying. As our technician said to us if it's not installed 100% and then all the programming calculations and mathematics are calculated it's not installed correctly. As a builder myself I have come across many cheap units and expensive ones simply installed at big costs by so called installers who have not had the training or the schooling to understand the mathematical calculations needed to get the formulas set into the computers. We were very lucky to have an expert who has run an industrial cool store installation and air conditioning company for many years and is a total book of knowledge on all forms of systems.

[@sophiegrisom]

In the U.S., heat pumps work best in middle states like TN. They are also common in Florida since few neighborhoods have natural gas. If the power plant uses natural gas to generate electricity, the overall efficiency with a heat pump is lower than using the natural gas directly for heating the house in an efficient furnace (condensing type is 95% efficient). A heat pump COP might be 3, but the efficiency at the power plant is 1/3 going from thermal heat to electrical power. Add in transformer and transmission losses and the overall efficiency is less.

[@BenIsInSweden]

Gas power plant efficiency in the US is closer to 45%.. The UK is just shy of 50%, and has one new gas power plant that exceeds 60% efficiency, with others planned to be upgraded to the same efficiency next year. Grid efficiency is only heading one way, along with heat pump efficiencies. The argument doesn't really hold much water today, because the grid isn't 100% powered by gas either. SCOPs in the UK can (in the right hands) easily achieve 4 or more, and I would imagine the US is the same.

He says that an immersion heater is used to top up hot water which is not true I all cases the immersion heater is just used for legionella's an immersion heater on a 1 per week cycle will probably use about 110kw a year which on average bill is £20 a year. Companies are supposed to provide all customers before installation, a full heat loss calculation result meaning the customer before installation should get. Full breakdown of running costs Full explanation of what radiators will be installed Full explanation of the heat pump itself Full explanation of the design and how it's getting installed. There are alot of companies out there that are just after making money but if done correctly the heat pump will work properly. The company I work for have literally installed 1000's and we don't even have a bad review so they not all bad. He has said you get a £4000 grant which isn't true either. I have a heat pump installed on my house and I got £11000. Here is an example of running costs compared to gas given on a property. So we will use the 11.2kw ecodan So example property information. 14000kw of heat 2500kw for hot water There gas is 3.5p per kw Electric is 15p per kw Total RHI (funding for this house) = £9833.91 Running costs per year for the heat pump = £786.49 Running costs for the gas is £577.5 So they are more expensive to run than gas boilers but not 3 times the amount like stated in this video and in the last 6 years I have never seen a heat pump drop below a 3 SCOP even at -5 degrees. So I have no idea what he's fitted before but they are not very good systems. Also he states that to get the grant you need to remove the gas boiler this is also not true he says that some houses don't have room for a cylinder which is true but how deal with this is we leave the current gas boiler if its a combi to provide hot water then we get the heat pump to do the heating and you will still get the funding. This system is called a heat only. The fact that he moved a heat pump to the bottom of the garden showed me he hasn't got much experience with heat pumps because if a customer asks me to put a heat pump away from the house I just wouldn't install it because I know it wouldn't work. This guy moved an heat pump to the bottom of the garden, so he either did this knowing it wasn't going to work and did it anyway or he did it because he didn't know it would cause issues either way it shows lack of experience. This video has some points and people need to be aware that there are people out there installing heat pumps that don't know what they are doing always seek professional and I will say one thing always check the reviews of the company if they install heat pumps because I will guarantee you that a customer who is not happy will leave a bad review when they have spent this type of money. So if you look at installers and 1 has gleaming reviews with no complaints and 1 has reviews saying my running costs are horrendous, my system doesn't work ect then you know that company is just a sales company making money and selling a pipe dream to the customer.

As an electricity distribution engineer I can say your video is spot on but you didn’t mention the billions of pounds the customers would need to spend to contribute to system reinforcement. Present distribution networks cannot provide the additional 15kW or so per house of additional load, especially in rural settings. This is compounded by the future need to meet the additional demand of car chargers. It should be noted that in the UK a typical distribution network is only designed to meet an ADMD (after diversity maximum demand) of around 1.5 kW per dwelling!!This is not a typo I don’t mean 15kW. Also note that ground source heat pumps are much more efficient but installation costs are also considerably more.

The 2010s was a decade of complete waste & inaction. It's true that certain types of houses aren't ever going to be well-insulated, but many could benefit from improvement. The investment in insulation is a one-off cost that keeps paying dividends over the years. Imagine we spent £10k per house on insulation in 2010. That money would have saved thousands by now and it'd *still* be paying dividends. Meanwhile, energy companies are making record profits as our heat leaks into the night air.

This is probably one of the most accurate pictures I've come across in terms of the use and effectiveness of heat pumps. As stated the government initiative to install heatpumps - particularly Air Source Heat Pumps (ASHPs) is going to be a complete disaster, initially for many of those who, in good faith, install them, and then for the politicians who will get dumped for coming up with such a stupid way of trying to resolve the climate issue - by suggesting that heat pumps are the panacea for resolving our carbon emissions issues. The truth is, as Roger points out, heatpumps are really excellent for modern, VERY highly insulated, homes, and are a complete nonsense for the vast bulk of the UK's old housing stock. I'd suggest that all the money earmarked for this half baked scheme be put entirely at the disposal of those who seek to insulate their homes to high standards. Or make the scheme available ONLY for those houses built in recent years with high insulation specifications otherwise we are simply wasting taxpayers money on a massive scale. The other obvious use for this otherwise soon to be mis-spent cash, is to put it towards alternative tech, such as nuclear, which not only provides the base load for our electrical network, but also doesn't emit carbon. I've used a heatpump in an extended 1930's house for the past four years so I can see how the new part of the house offers good results, why the old part doesn't. My electricity bills are three times higher than they were previously for a system that cost £16k and a variable heat profile - not a good result overall. This is not a question of folk being anti this technology for the sake of it, because it does work well in certain circumstances, it's just that these circumstances are rarely met. The calculations for standards of insulation that have to be met before a heat pump is installed (seen to be worthwhile) are, in my opinion, far too low, so many HP's will be mis-sold even though 'on paper' they appear to be the right solution. Generally they will not be. So please someone, get Roger in front of decision makers and stop this car crash happening and let's take a more measured approach and provide better solutions to resolving the climate crisis!

As a science teacher you should know better. First and foremost, electricity is undepletable source of energy, you can extract it from everything that moves...what about gas? What about oil? He is talking about "drafty" houses with no insulation. Who lives in house like that and have money for heat pump? Every house like that is just wasting energy and it should be fixed first no matter what energy source it is using for heating. Also, he talks about radiators, they are things of the past. Underfloor heating is most efficient way of transfering the heat since you heat up large portion of the object and as we all know the warm air is lighter than cold air and on his way up from the floor it is heating up everything on its path. If your house is insulated, the heat pump will be great invest. It will keep you warm no matter what taking into account that you installed the heat pump with correct capacity. Also, heat pumps are nothing new, they are old as your fridge is, it is just reverse cycle. He talks about prices of gas and electricity. Well, guess what? You can produce your own electricity, but I am sure you cannot extract gas yourself. The thing he talked about heat pump installed under the tree is just nonsense. Listening to him is just like listening to oil company manager talking about electric cars. I have seen heat pumps working in cold weather just fine. Also, never heard from anybody that heat pump cannot heat water tank. Backup heater is just as it says, "backup". If there Is a need for auxilary help from the heater, the heat pump will use it but for a short period of time. If whole family decides to shower one after another they will quickly drain 200l tank, if heat pump decides that it doesent have the power to heat it up fast it will acitvate tank heater. I know that Panasonic Aquarea, 7 kW, split heat pump, heats up 140m2 of space with underfloor heating and with water tank of 270l while outside temperature averaging 3-5c in winter for 70€ a month. In that 70€ electric bill is everything in the house, not just heat pump. And it is installed in shade, behind the house, away from the sun. I know that because I installed it to my friend. The location is Croatia. The whole project, with floor heating installation cost around 15 000€. Just scroll and read comments from people that owns them. Nothing is perfect but for now the heat pumps are great solution.

During defrost or below 15 the gas furnace or electric air handler$ is running. They don't last as long as a gas /ac unit. And even less if comparing to a boiler. With that said, I do have a new heat pump in a building that has no gas.

I love this channel, but you are wrong. Even at -10 degrees last winter I was getting a COP of over 3, maybe it’s you… my house is a bog standard 1980s house. Also the legionella cycle only runs for 1 hour every two weeks. As for the level playing field for fuel cost, electricity has a 22% green levy applied before VAT, gas only has 2% green levy before VAT, so basically electricity has been subsidising gas for over 10 years. Your bias is so blatant here it’s shocking.

[@SkillBuilder]

Muppet Keeper, tell us more. I would be really happy to be proved wrong. Tell us about your house and the heating system, how long you run the heat pump and what size it is? I am here to learn

[@Festoolification]

Aren't those electricity levies basically subsidising the government's last scheme - the solar FIT scheme which basically gave all the benefit to a few users including a few large landowners and passed the bill to everyone else?

[@Muppetkeeper]

@@SkillBuilder Ok, it’s a 1986 4 bed detached, double glazed with the cavity wall insulation that was put in at build (approx 55mm of glass fibre). Loft has 300mm glass fibre. So basically nothing special for the age of the house. System is a 8.5kW output Mitsubishi Ecodan, which replaced a gas boiler that broke. Radiators we’re up sized, and the flow temp set at 45 degrees. I hope that you’ll agree that in Yorkshire last winter it was really cold, but the house was at 20+ degrees all throughout. The heat pump needs to run almost constantly at -10, but it has variable input power, so not using 3.5kW all day every day. I will accept that a good proportion of heat pump installations are complete bollocks, usually done by housing associations or councils, who don’t do the necessary work to determine if the systems are suitable as they stand. My advice to anyone considering a heat pump, get a proper heat loss survey, buy it yourself from an independent surveyor, and listen to what they say, if they say don’t do it, don’t. Another proportion of failed heat pump installations are due to the clients refusing to up their radiator sizes, but go ahead with the installation anyway. Writing off a whole technology isn’t fair, but it is more risky than chucking another gas boiler in.

[@Muppetkeeper]

@@Festoolification No entirely, it all goes into a big pot, some of it was even spent on coal mines… My point is that gas nd electricity are almost equal in pollution causing now, so why charge electricity customers 10 times more in tax?

[@hugheaston7598]

The green levy on electricity is to pay for all those lovely windmills, and to subsidise the biomass industry. Both things used to generate electricity. That's why the levy goes on electricity.

[@robtorres5518]

Most thoughtful rant I've heard in years. Truth is, electric will never be more efficient than fossil fuels. Hybrid cars bridge the gap, figure out a hybrid heat/cool system.

[@SkillBuilder]

There are plenty of hybrid/gas heat pumps now and I think they are the way to go.

[@RLFWE1]

Get your own back, by having multiple input heat sources into the buffer tank/thermal store. That way you can keep an old secret gas boiler and maybe add a back boiler on a wood burning stove. Then you can enjoy virtue signaling that you have a heat pump whilst secretly heating your house with coal or stolen wood which delivers reliable output on freezing cold nights.

[@SkillBuilder]

The buffer tank thermal store is a brilliant idea and I completely agree. We should have as many options for heating as we need.

[@randymugwug5247]

If you are replacing your A/C for some reason. a heat pump can be feasible. In some areas a great deal of heating costs are not when it is really cold, not realistic below certain average temperatures. In ground systems are or can be very expensive ,but the return on your investment may never happen.

[@TYRONE_SHOELACES]

I look FORWARD to when a guy knocks on my door and tries to sell me a heat pump. I am in Halifax, Nova Scotia, Canada. As soon as he starts with the pitch about saving money, I tell me will I save money in service calls, maintenance upkeep also?....Because my house has all electric baseboard heating...a system that was installed in the house when it was built in 1986 and TO THIS DAY, not one dollar has been spent on upgrades, maintenance or service calls. I told him that there has never been an improved style of baseboard heater since their invention ...and my mechanical thermostats have been on those walls since 1986 and NOT ONE of them is defective to this day ...because they are mechanical, that's why. I said I have 3 floors in my home so I would need three separate units on each floor, but then I would have to leave ALL the doors open on second and third floor to heating those rooms, and the chances of having teenage girls leaving their doors open all day and night is an absolute joke. Right now I have a baseboard heater and one thermostat in each room which seems to be working just fine. I can't stand a draft in my home. I have NO WIFE in my home so there's no fan blowing cold air on me all night while in bed because I DO NOT suffer from hot flashes. I hate sitting in people homes while their heat pump blows cold air on me all evening while sitting on their couch. Heat pumps are expensive and as soon as the warranty is up, so it the motor, or the freon starts to leak, or a circuit board, mother board has been fried and needs complete replacement. I have to ensure that the snow does not build up around the unit outside, I have to ensure that the snow on my metal roof does not slide off and damage the heat pump all winter. I have to ensure that the next door kids do not damage the fins of the outside unit. At work, the lunchroom wall is lined with a dozen heat pumps and usually there are 3 of them leaking water onto the floor, causing mold and floor damage. Nothing is uglier than having these huge white PVC covers screwed to my neighbours siding to hide the insulation piping that snakes up the front of their homes and then snakes across to the hallway. Just ONE length of that "pretty" plastic covering cost over 800 dollars to purchase, and you HAVE to have it to stop sunlight from deteriorating the black insulation. I have a 5000 BTU air conditioner that I got from the Salvation Army a few years ago that is in my kitchen window. When I come home from work, I turn that unit on and I have cold air in the kitchen for hours while I prepare and cook supper. I then place a small fan in the doorway that blows that cold kitchen air into the living room, cooling the whole living room all evening ...cooling the living room to the point that I have to turn that tiny, 5000 BTU unit DOWN or it's too chilly. I have another 5000 BTU unit in my bedroom that is perfect for chilling that very large room, my teenagers gets cool air upstairs by running my AC in the bedroom and opening my door. My basement level gets damp in the summer so all I need down there is a dehumidifier, an air conditioner makes it too cold, by the time the humidity is gone, the room is too cold, so a SMALL dehumidifier is more than plenty, turned for 2 days, left off for 3. My house is drafty, my windows are old, my patio doors and entrance doors are original, waiting for the dam dog to die before I change them, he scratches the hell out of those doors and patio doors. By now, the heat pump salesman has already started to walk away because I won't stop talking about how bad heat pumps are, as he is walking down my driveway, I am explaining to him which neighbors I have already convinced that heat pumps are the worst investment you can purchase. I tell EVERYBODY that by the time the heat pumps have " paid for themselves"...which is 10 years down the road, NOW it's time to purchase all new heat pumps, so the cycle continues where you think you are saving money, but you are NOT. They are NOT a stand-alone unit that does not require regular upkeep, and when they even just start to get bad, you have to listen to that fan motor whining or rattling every time it starts or stops.

@@Commsfarage I agree, there no reason to remodel heating and cooling when what is existing was all good and approved at the time of final build/inspection. I prefer natural gas heating, air conditioning and cooking for the most part. BBQ, gas torch etc. Just how will my bunsen burner work without natural gas?

[@vincentbentley1079]

@@Commsfarage The government will just make it impossible (or unaffordable) for you to get home insurance with a 'polluting' heating system just as they have done with vehicles. However, it is strange that the UK's once largest coal power station now burns wood pellets from Canada where the tonnage that they burn in a day takes 80 years to replace. I guess a lot of Canadians haven't yet realised that they are living on a bigger version of Easter Island.

[@tedstriker754]

I've got two heat pumps for winter heating, backed up with heat strips. They work fine, but the idea of using a heat pump for heating water is ridiculous. It would never get the job done adequately. One of the worst ideas ever.

Grants are around £10,000 Not £4000 Systems are around £13,000 My system is completely covered by the grant!

[@RubenKemp]

You live in a warm part of the UK then? What are the running costs? How's the noise?

[@_a.z]

@@RubenKemp Central UK Fuel bills have gone from £1200 for a cold house on gas, where we used to switch it on when needed, to a house at a constant 20 degrees, hitting about 21 max, down to 15-17 overnight, costing half that! Bills are below £1000 but we bought an electric car and solar, so difficult to tell exactly. Expecting to get bills a bit lower still. Petrol + gas + electric was £1900/year. Definitely halved now its all on one bill. Had gas supply removed too! These are probably not for folk that want to heat to 28 degrees in winter though.. They also need to be fine tuned, not something the install company did for me, although they promised to make repayments equate to install cost, that assumes moderate inflation. It's panning out well, cash in a small pension and effectively you start to draw it by receiving the RHI payments, or bank it again. The heat pump is then free or close to, without any financial stress! Noise is fine, they rev up sometimes when they start up. Then go quiet. If they have to work hard, it's in winter when everyone's indoors. Not likely to keep you awake though!

@@RubenKemp House is 1960s insulated cavity, old plastic windows, 8.5kW Mitsubushi Ecodan 5 bed. I have 2 friends with them too, one very happy, the other lives in a massive stone house and is having problems. You do really need to fine tune temperatures and timing though, and set to reasonable living temperature. Never tried it above 21 deg though.

[@RubenKemp]

@@_a.z sounds good! What happens when it rains for a week? Do you have to basically heat electrically at that point if you want to take a shower? I ask that as I read that the ecodan is 'the only system on the market' that doesn't use an additional electric heater or pre-heater.
