Skill Builder V Heat Geek | Heat Pump Argument | Part 2

[@inanepunk475]

Followed over from SB part 1. Really enjoyed the video, you both handled yourselves well and it was refreshing to see two people that have differing views have a friendly debate without coming to blows - this world could use a lot more of this. Hopefully some more of Rogers ~500k subs will help your channel grow. Looking forward to seeing Roger at an installation, so please make that happen. Keep up the great work.

[@billysmart24830732]

@@HeatGeek I came over from Skillbuilder which historically has been brilliant. Roger is just angry at the World and doesn't know why or at least cannot make a fact based summary that explains his rantings. He never used to be like that, this last 6 months or so he has ventured into the realms of conspiracy theory and unstructured tirades. He agrees we need change but then rages against things that provide it. Yes, electric vehicles are not perfect for every role but don't say electric vehicles are rubbish because they performed poorly in one speciffic role. Anyone who quotes their source as the Daily Mail, refers back to the Thatcher days and wants us to go back to how it was needs to be wheeled back in front of the TV and given a chewy toffee to shut them up. As for the difference in channel feedback, don't be too bothered by it. Anger is much more likely to provoke a reaction which is why the Daily Fail talks such crap, it sells papers. For it keep working, you have to continually talk crap e.g. Fox and GB news etc. Better to keep your credibility and continually grow and diversify. If you setup another channel, you already have my interest to check it out based on what you have done so far with this one. For me, Roger has taken a huge credibility hit and regularly switch off as soon as he gets politcal.

[@filthebeats]

@@HeatGeek your initial video reaction to his was not exactly unbiased and almost dismissive of Roger and his knowledge and experience. However it was good to see you both get through a sensible discussion allowing you to both to get your sides over to the audience, the mere fact that you arranged this discussion shows you are both better than the current PM leadership candidates. Adam and his partner are clearly intelligent and making great efforts for a young industry but being more realistic, open and upfront about where the heatpumps will be appropriate would be better. No one will want to live in suburbia with a drone of these pumps going on and as discussed, the majority of families don't have the cash to change their heating system for green issue benefit

@Jim Snead I think not 😂 he’s a white van man that specialises in nothing. Heat geek specialises in this field, I’d trust they know better than him. Gas isn’t an option clearly he hasn’t came up with a viable alternative than him bodging a heat pump install for a customer once and they weren’t happy

[@Progen77]

@Jim Snead The Old Dog speaks practically, the young pup talks about potential, the future, optimizing insulation, perfect installs and "carbon". I believe in an inperfect world where installs and insulation are crap and gas is the most reliable in that situation.

[@johnbull5394]

@@Progen77 You sound like me a few years ago. I was really anti the ban on normal lightbulbs. As I had some of each type of lightbulb and knew where I wanted them (and I knew how to turn them off). Then they banned normal lightbulbs and LEDs got so much better that I actually replaced lightbulbs that were still working in order to fit LEDs and, 6 years on, I'm still very happy with them. If you ever go to Sweden, have a look at the buildings around you. They don't seem to have the crap building we allow in this country. So what I believe is that if we accept crap because it's inevitable, that's what we'll get, but if we seriously decide we have to improve matters, we will. Obviously there's no point in banning gas if we're still happy to allow shoddy installations, which I think is where we agree.

[@Progen77]

@@johnbull5394 I agree with your points but a second element of my thoughts is that I do not see high quality heat pump tech in the US. My best friend owned a Heat/AC company and he loved Fujitsu units. He was like the King of Mini-split units in NYC. But he said that once the air got too cold they could not effectively pull heat when there was not enough heat present. Once the air was below freezing you were done. He advocated it for warmer states and as a secondary heat source that saved you money at medium temps in cold states. Not as a primary heat source in cold states. I have not seen any tech in my area that would dispute that 😎

Love both channels and really enjoyed the debate. Great points raised by both Adam and Roger and you're both great communicators and presenters of information. One thing I will say is regardless of your opinion on heat pumps currently, the industry will become a car crash without people like Adam and the Heat Geeks who strive for better design, better knowledge, better training, better technology, better installs. The passion really shows through.

So easy to only see content on one, potentially inaccurate, side of a debate. You need to actively seek out the alternative opinions and not just let KZbin's algorithm serve up content that reaffirms your bias.

[@chualarbill]

I really wish we could integrate the Heat, AC, Clothes Dryer, Refrigerator, and Water Heater into a single interconnected system. (Ground Loop, Heat Pumps, Solar Pre-Heating, etc. ) Create large hot and cold storage that can be tapped as needed throughout the day. Sometimes you may need to just dump heat, or cold, but otherwise, it can be recovered and put to use...

[@Accringtonman]

Thank you both and well done for generating more light than heat, which too many debates fail to do. Roger mentioned leak detection, so here's a throwaway idea I never got to try on a real system (retired now). Vehicle screenwash (possibly the anti-freeze component) sets off a combustible gas detector (try taking the lid off, putting the sensor at the mouth of the container and watching the detector go crazy). It should be possible to put some screenwash in the system and use the combustible gas detector to hunt for leaks. I assume it would need to be flushed out afterwards.

Both Adam and Roger are doing an amazing job of explaining key issues related to our journey to net zero in our heating systems. We will all be much happier if we at least try to solve the problem of climate change. If China and others don't play ball and the worst climate scenarios happen, at least we know in our hearts that we've tried. If there are a few bad heat pump installations due to the speed we must move, that's an acceptable price to pay for real progress.

[@timbdesign]

I am a member of public but not a plumber and wince at the amount we are spending to heat a house built in 1990 with gas! A neighbour has installed a heat pump but went back to using his gas boiler as it was costing him more to run the heat pump. I suspect it wasn't designed properly for a property with microbore pipes. If I could get an assurance my heating costs would be no higher with a heat pump I would go ahead, solely to help cut carbon emmisions for our children and grandchildren. I'm hoping to persuade our daughter to switch from gas to a heat pump and, if succesfull, will be paying Heat Geek to survey their house. I'm really impressed with their knowledge and ability to explain technical things in a way I can understand. Keep up the great work!

Fascinating discussion. And this is why I’ve opted for a new boiler rather than going down the heat pump route. Over a month just for a surveyor to come out. At least 5 months until an installation (and prob delayed again). Huge upheaval and changes to the home. Lack of service engineers and potential problem with parts. I’m sticking with a good old reliable brand new Worcester Bosch boiler for the next 15+ years.

[@reinmansmith]

So good to hear a proper sensible discussion on a subject, full marks to both of you. It’s a rare thing these days. 👏👏

[@stauffap]

Not really sensible. A lot of what Roger is saying isn't sensible at all. You can't keep using gas and oil heaters. He does not really seem to understand that. If i had to guess, i would say that he doesn't really understand much about global warming i.e. he's misinformed about it. You can't just look one technology, if you want a successfull energy transition and achieve carbon neutrality. You actually have to ask how a completely renewable energy system can work. And we just don't have enough renewable energy to use 3 or even 10 times more energy in the heating sector i.e. we can't afford to not heavily rely on heat pumps. They BY FAR the technology that uses the least energy. Nothing else comes close to it. Well, actually better thermal insulation would also have a large effect, but most people can't afford a better insulation AND a heat pump. And just getting a better insulation while sill using an oil or gas heater just isn't an option. If you look at studies about the energy transition in the UK, then you'll see that there are enough potential renewable energy sources to achieve the full transition away from fossil fuels, but not by much. It works with heat pumps and electric cars, since they reduce the primary energy demand drastically (by about 70 percent), but it probably won't work if we want to heat with hydrogen and drive cars powered by e-fuels. The UK doesn't have that much energy.

[@pingxingming]

@@stauffap Talk about jumping to conclusions. Just because someone has a different opinion, that doesn't make them uninformed as long as their points aren't refuted. I don't think SB disagrees with your otherwise balanced view even. I at least agree... The name of the game is "potential", though. Potential alone won't heat drafty British homes.

[@stauffap]

@@pingxingming Of course potential alone isn't enough. It has to be done of course. But it's economically and technologically possible to have an energy system without fossil fuels. Again, there is enough in the scientifc literature about this. We now know that it's possible. So, i don't really see why you shouldn't be able to heat every "drafty" home in Britain with heat pumps. If a central heat pump isn't an option, then most of the time a AC (mini split heat pump) is works. What's also great about AC's is that you could keep your fossil fuel heating system and use the AC to reduce the energy needed from fossil fuels. The effect is a lot bigger then people initially think. For example, with an AC that has about half the heating power of your fossil fuel heater, you can cover up to 70 percent of your energy requirement. And the explanation of why that is, is quite beautiful. After all most of the year you don't need the full power of your heater. So most of the year can be covered with only the AC. The full power of the oil heater is justed need on a few of the coldest days, but even at those days you can still cover half of your heating requiremment with the AC in our scenario. So you buy an AC with a certain percentage of your maxiumum heating power requirement and you can replace a substantially higher percentage of your fossil fuel. Another great thing is that the investement is small and you can switch gradually to less and less fossil fuels, which is totally ok for the energy transition. I'm convinced that it can be done. The information just hasn't been able to reach the general public.

[@pingxingming]

@@stauffap You raise many important points and I share your optimism, I'm just wary of all this glossing over of upfront costs and lack of trained installers; I think the government is doing the cause a disservice if they push too hard just yet. But you've given me much to consider. Thanks.

[@stauffap]

@@pingxingming I'm a bit confused. Why do you think we need qualified installer to install AC's? That's pretty straight forward as far as i know. With quick connect systems it could even be done DIY, but that's not allowed currently due to bureaucratic hurdles.

I have a condensing system boiler that was fitted in 2006 with a megaflo cylinder. After watching yours and SB videos I have upgraded my loft insulation, having new doors and windows and upgrading all my rads to type 21 & 22. If I go down the heat pump route, how do I heat my hot water? Do I lose the megaflo? I also have solar panels with a sun system that takes the excess produced power and diverts it to the immersion in the cylinder. It works well apart from when it isn’t sunny obviously. I am currently also fitting the Drayton Wiser system.

[@HeatGeek]

I wouldn't bother with the wiser system. It will mean you use more energy with a heat pump (and not save much with a boiler either as micro zoning is inefficient). Your unvented cylinder could.be ok woth a heat pump.. unlikely if its the mega flow brand though.. inwhich case it will need replacing

[@laurencelagden]

@@HeatGeek thanks for replying. I have found with Wiser TRV’s I have a room or two which have a larger heat loss than others still calling for heat and keeping the boiler running which means it cycling. It really does take some thinking about to make it run efficiently but also not so complicated that only I know whats going on and how to control it and also not have to look at the app 20 times a day.

[@johnh9449]

Great to hear the conversation. One major thing that's been missed is the combination of solar PV plus battery powering the ASHP. With that you can effectively go off grid most of the year with the summer surplus charging your EV so you can "drive on sunshine", with cheap rate electricity supplementing the ASHP in winter. The running cost saving is huge and very green.

[@singlendhot8628]

You can't be a solar PV owner. PV doesn't generate enough to cover non-heat pump electricity consumption during December and January, even for an efficient home, which are peak heat pump usage months. Good in theory but not in reality sadly.

[@goncalovazpinto6261]

How about instead of PV using solar water heating to complement heat pumps? More efficient transfer of energy, simpler system, much cheaper. You could circulate the water in the system through solar water heating panels during the day...

Great discussion- I followed both Rodger’s and Heat Geeks videos around heat pumps. Firstly- this is how conversations should happen. If only the rest of the world could follow this example. It’s very easy to close the conversation. Heat networks were mentioned fleetingly- I’d be interested in thoughts around this topic. Probably using both heat pump and possibly hydrogen boilers serving multiple buildings - particularly in cities and towns. I think the emphasis on this is a similar point with heat pumps. The success of this is down to the design and installation. Similar horror stories with initial projects in the UK as that industry is in its infancy stage- but on paper- mass decarbonisation quickly/ no tank/ low cost and familiar look and feel for homeowners.

(Disclosure - I have a full heat pump system installed in 2011. Mixed feelings about it. Note that our system does NOT have an electric heating element and will raise water to 55C throughout the year. So we do not feel cold, but in the winter it is very expensive. The whole system was designed for the house - house has huge double radiators etc etc).

[@MattOxley1401]

Top class respectful debate. Reducing embodied carbon and energy use is the biggest challenge of the next decade. Credit to Geek Heat for putting some great info out there.

[@nervousfrog101]

One thing possibly worth mentioning is that heat pumps are a lot better at using diverted solar PV from my roof than gas boilers. If you can run your HP during the day on electricity from your PV and battery storage and then use cheap rate(low co2) electricity at night they will be a lot cheaper to run than a gas boiler and produce a lot less co2. Totally agree on the carbon tax and insulation points.

[@scottpeters8142]

I'm sure no one will disagree that is the ideal situation, however, your talking about 20-25k for a full heat pump install with a PV and battery storage, and that's before addressing any improvements in insualtion. Sadly, the vast majority of people will never have that kind of cash to fit it, and as much as everyone would like to go green, it will always boil down to cost

[@nervousfrog101]

@@scottpeters8142 Green tech is no different to other tech the early adopters pay extra to get in because it's something they believe in and that allows the industry to scale up and lower costs. Just look at computers, mobile phones etc. I started when I had no spare cash by taking advantage of home insulation grants and then upgrading insulation where I could. I have had solar panels for 11 years now. I borrowed the money to install them. The FIT has paid back the loan and now the FIT is funding the rest of my green upgrades. The same with my EV. I bought the car on PCP the savings in running costs are paying back the extra cost of the car. You can invest in a windfarm from as little as £25 and upgrading insulation is certainly cheaper than energy costs.

Well done to both of you for a good spirited and important discussion. It was a little frustrating seeing Roger trying to drag it into a political discussion but there was lots of valuable knowledge from Adam and cold hard facts. The heat pump saynayers need to come up with solutions not problems.

[@stauffap]

You don't need 15'000 to install a heat pump. AC's (mini split heat pumps) are also heat pumps and installing those is quite cheap. And there's a very interesting effect with such heat pumps. Because even if such a heat pump only delivers about 30 percent of the heating power of your oil or gas heater then it will actually reduce you CO2 Emissions by far more then 30 percent (up to 70 percent). Everyone has to money to do that. And with time you can even expand the system with more AC's and eventually get rid of your oil heater. The great thing is also that you don't need any of that fancy system design to achieve a high SCOP since the outside and inside unite are already perfectly adjusted to each other. So, it's just a myth that heat pumps are expensive or difficult to install. Most of the time people, who say such things ignore mini split heat pumps or AC's.

[@gasfitter78]

Great video!! in my opinion customers' attitude has not changed in the 20yr I've been in the industry the general public is self-centred and doesn't have the time to research the installation of a heat pump. They are more interested in a no-talent family "Kardashian" or the next love triangle in love island than looking on their phones or tablet to look at the central heating design as long as big companies can promise one size fits all installation and promise to make installation stress free your message will fall on deaf ears. I don't think you'll see the results until the end of your working life unless there is a big change in public opinion. But I commend you for endeavouring and keep up the fight for low-temperature heating

[@ram64man]

totally agree with Roger - we do need an independent energy policy, I'm fortunate enough to now own a us home as well with duel citizenship, i have gone from oil heating to a heat pump, into a new European style home, right now the us are currently 10 years behind the uk in insulation and heating in general, even with the green push with off grid propane being the only alternative we went down the heat pump route, (granted the building is not finished at this time but is insulated to 20mm - this will be supplemented this year) even with the underfloor piped heating, the building still felt cold (granted it did fall to -14c) but with the home even with a multi split twin 28000 btu equivalent it still ran on the direct electric heating bypass every time it froze over (and went into a defrost cycle) the energy used even with a cheaper rate totaled 1200 dollars in electric, no one can afford that sort of electric usage. my uk 4 bed home based on this experience (and nothing to do with the pain in the ass protestors) insulated, insulated, insulated, 250mm externally, 25mm internally on external walls, 300mm in the loft, the property had what must have been the last oven vent regular installed in the 80's i now have a 25kw system boiler, that is supplemented with pv in the roof heating a 250 liter A rated tank, that again was extra insulated right now because the insulation (including two room heat exchanger vents) the heating is Off, the PV has heated the tank even from half empty ever since march by its self in the day with twin solar diverters. everyone talks about 3.5 SOc but the fact is the cost of that electric is rising to ridiculous levels, PV isn';t the way , there is this misconception that 6-8 panels can cover your energy usage, sure in summer with a 8kwh battery its great, but forget about it in winter my 10kw us install just generated 1,3 kwh in a day in december, all these heat pump installs just don't make clear just how much energy is being used even with a 3 cop rating your still looking at £anywhere from 700-900 pounds to run each year. not to mention the fact that the majority of 80's or older houses just still don't have underfloor or even correctly sized rads its not just social housing that needs upgrading, if anyone is thinking of direct electric heating or hot water boilers forget it, even with off peak rates it will cost an absolute fortune. we cannot have a repeat of the nibe incident with our future, i still strongly feel there will be mix of hydrogen into the network to SUPLMENT a change, but what that future is is not and SHOULD NOT be heat pumps alone. and why I still like a direct gas equivelent, no one is talking about with hydrogen your usage goes up to old gen boilers due to it being less efficient to current gas

I love how skilbuilder uses the language that we hear in the oil sponsored media, just because more wealthy people can afford it now, it’s the first part of the chain that starts to reduce prices as we get to scale with production. These is an enormous reduction in Carbon dioxide from heat pumps. His whole argument is we’ll need more stuff and it’s different to what we’ve done, and I don’t like it, innovation brings change, some win, some loose but that’s how we move forward. The big effort should be on the insulation of properties and much higher standards for new builds which should be passive. If other countries can do it, why should we be proud to lag behind.

[@davideyres955]

Enormous reduction in carbon dioxide from heat pumps? You do know that on average 50% of the power from the grid is from gas fired power stations that run at around 30-40% efficiency? Generally the heat created by these power stations goes to waste. (Should be used for community heating) With the extra electric cars flowing in the requirement of the grid is going up all the time and the problem is renewables are intermittent. So we need something that can vary quickly and your back to gas. Heat pumps are great in the right situation but not all.

Especially as I live in an apartment block and it’s very well insulated.

[@effervescence5664]

We're all in agreement that infrared panels are crap and Amptec units are stupidly expensive considering 100% efficiency. Low temperature design is new to domestic but it's been a staple of design in commercial for a good couple decades now, it is nice to see day to day how much better heat pumps are getting though we're still waiting the best part of 6 months for pumps and boilers for commercial applications currently and it's getting near that for domestic appliances what with the current situation in the world. Weather comp is great but we've always found it a pain for older people, gas or heat pumps because they prefer the higher touch and air temperatures or they feel cold. 30:30 Oh god, the two day install thing was hilarious we've been to a couple sites like that to identify issues and yes it's eye opening. The issues with the ASHP units are fairly typical of the issues we first had over here with AC units. Ah yes the age old Copper Vs Plastic, ideally always copper but given the costs of installation and time plastic I fear will be the go to for the majority of companies. We personally are Copper, press fit or solder as it just inspires confidence in your own work and customers appreciate the perceived quality. Like the Heat Geek site, Gas Safe and others need accredited lists of installers as there are unfortunately so many companies that have jumped on the wagon and aren't currently. Rogers points are good, there's going to be more horror stories given the grant but we've already been rectifying heat pump installations that were put in over the previous decade, some less than 2 years old. It's nice to see you've both realised you're both actually on the same page. It's very much the same discussion I've had with my business partner as he came from the domestic gas and plumbing side and I came from the electric GEC Nightstor side.

[@stupidusername38]

I'd like to know more on why infrared panels aren't great. I'm interested in investing in far infrared heating to be installed on the ceiling of each room in my house, but both Adam and Roger seem very dismissive of the tech. Is this due to the inability to provide adequate heat or the costs of running a system directly from electric? I'd be powering them from solar PV

[@johnh9449]

@@stupidusername38 I suppose it's because they are only 100% efficient as opposed to 350% ASHP if run directly from mains electricity and more expensive than a gas boiler 7.5p p/kWh even with its 90% efficiency. With off peak electricity they could compete successfully but only for a few hours at night. Running from solar PV is free but driving an ASHP with PV is still far more efficient. Where they are supposed to score is from radiance to the person rather than heating the building but that will drop by the square of distance and can be blocked by objects. There was a better person heater proposed - microwave - which only heats the water content in your body but worries about it frying your brain meant that was a non starter. Probably a woolly jumper would be best.

[@effervescence5664]

@@johnh9449 You've got it, only just seen Nicks comment. Another issue that people don't think of is although they're good at heating surfaces in direct line of sight they take a considerable time to heat the fabric of the building. Thus a person may be warm but the property can still have mold issues due to lack of air circulation. Also panel placement and square area heating can mean lots of ceiling panels in the way of lighting etc to get the same effect further reducing its cost effectiveness.

[@Peter-hm4oz]

@@stupidusername38 We're installing far infrared panels throughout our house for this winter and have been trialing them for heating several rooms for the past 4 years (with detailed energy monitoring). They have their limitations, they use electricity which is more expensive than gas currently and won't achieve a COP of 4 but are better than is implied in this video. The research by independent groups have shown that a similar level of comfort can be achieved with roughly half the number of kWh of energy providing a COP equivalent to 2 but this is only when control systems are well designed (presence detection, lower air temperatures etc) and panels are suitably sized. With a smart enough control system, you can take advantage of small chunks of excess solar output to run a panel at a time cycling through them where the lack of zoning for a heat pump and higher energy usage for a heat pump (compared to an individual panel) would lead to importing energy when you might not need to at the edges of the heating season. In terms of capital investment, for the cost of a heat pump + installation you could kit out a house with far infrared, install a decent sized PV array and get a home storage battery. Or invest in very high levels of insulation for the property, or just save several thousand pounds. We are expecting our usage costs to be higher but we think our total cost of ownership will be lower - no need for gas standing charge, no need for annual servicing, unlikely to require repairs (replacement compressors etc). There's also a benefit in terms of risk management - no single point of failure, if a panel dies we lose heating in one room, if an ASHP requires maintenance we have no heating. If there's a power cut, we can run a few IR panels from a home storage battery for several hours but we probably wouldn't have the output to kickstart the compressor on a heat pump.

[@stupidusername38]

@@Peter-hm4oz thanks Peter, really good response. I've decided to go the ASHP route however what I may consider is installing far infrared as well in certain rooms in case of times where the heat pump may need servicing.

[@yatasee]

Great set of videos. Whilst I'm very pessimistic about anything government does these days (I'm mid 30s) I could offer one optimistic view on the boiler upgrade scheme and compare it to the solar FIT scheme's beginnings. There's no denying when it first started when FIT payments were in the 40p/kWh range and the installation costs were huge that only the most affluent folks could afford to install them. Never the less over time it did kick the solar industry into high gear and brought more solar investment in both technology, price as well as training to the point it's far more affordable now than it was back then. I could see something similar occurring over time with the move towards heat pumps if adoption starts to build. I also think there will be a point where we need to stop with the carrots and get the stick out which will be to re-balance electricity vs gas levy's as Adam mentioned. I think so much of the "gas is king" movement is centered entirely around false economics that gas is significantly cheaper than electricity. If gas + electricity costs were more on par (or even the other way round if you added some kind of carbon tax into the mix!) then the shift away would be so compelling and undeniable that mass adoption would take place. Don't ever lose that optimistic drive Adam+team!

[@blahblah1234392]

Interesting debate but I tend to agree with Roger that as things, without government subsidies, it is still far cheaper to heat your house with a condensing gas boiler. Taking into account efficiencies and distribution losses, 1kWh of heat into your home with an ASHP is £0.11 and for a condensing boiler it is £0.08. Assumptions: Gas £0.07/kWh; Electricity £0.28/kWh Gas boiler COP 0.9; ASHP SCOP 2.5 I hear the argument about SCOP but it’s somewhat misleading because it’s not weighted to take into account sessional usage. The reality is that you use the ASHP the most when it’s cold and at its lowest COP. I have an ASHP and when it gets below 6C outside it’s consistently going through a defrost cycle. In terms of CO2 emissions, things change. How much gas was used for 1kWh in the home? Gas 1.12; Electricity 1.01 In the last year, 43% of power generation was from fossil fuels, taking this into account: How much gas was used for 1kWh in the home? Gas 1.12; Electricity 0.43 Assumptions: Energy conversion efficiency (generation): Gas 100%; Electricity (from Gas) 44% Energy distribution efficiency: Gas 99%; Electricity 90% Energy conversion efficiency (consumption): Gas boiler 90%; ASHP 250% Looking at the power generation as of today 20-7-22. 43% fossil fuel; 19% wind; 15% nuclear. The last nuclear power station was commissioned in 1987, 35 years ago and yet it makes up nearly as much as wind. Successive governments have failed to provide us with any meaningful long term energy strategy and only in 2016 was the newest nuclear power plant, Hinkley point C, commissioned to replace Hinkley point B due for decommissioning this month. The green Levi makes our industry globally uncompetitive and hits house hold bills hard, in the 21st century affordable energy should be a human right. Of the energy we buy, only 36% is the cost of the energy, 18% tax and 2% profit.

[@NoahSmith1]

Great discussion! I do think Roger's statement about heat pumps only having a marginal carbon benefit should have been more rebuffed though, as he's still repeating it and it seems a core part of his hesitation towards heat pumps. The embodied carbon in a heat pump is only 4% of the lifetime operational emissions of a gas boiler, so you could replace your heat pump every couple of years and it would still be better! I did try and post a link to the source, but I think youtube then thought the comment was spam.

[@SkillBuilder]

Man made CO2 is at most 3% of total carbon. If heat pumps reduce it on a global scale it will make 0.0000001% at best. If you seriously think that this stunt will make a difference to climate change you are deluded. Do things that work. Even climate change experts will tell you this is nothing more than a publicity stunt. Every year thousands of delegates fly to a resort and discuss the impending crisis and make pledges that they fail to keep. In all that time CO2 has not been reduced by one gram.

[@chrisfairbrother4077]

Interesting to hear your thoughts on infrared heaters and electric boilers, my biggest concern with a heat pump is the running costs and that you can’t benefit from cheap nighttime electric if you’re running it during the day. Because of that I’ve been looking at things like the ZEB which you can charge up at night and take the heat out during the day. I appreciate it is not as efficient as a heat pump but when you can still get electricity at 4.5p per kw at night it must be cheaper to run than a heat pump.

[@HeatGeek]

You can still heat hot water during that night time, at much higher efficiency. you can also heat a buffer.

[@Sean006]

In the future - when more people have electric cars - one may be able to charge the car on cheap night time electricity and power the heat pump from the car during the day (or even better from solar panels). Obviously the range of the car will be diminished.....but I doubt most people don't drive to maximum range every single day. Smart homes in the future will be able to use electricity in clever ways.

The problem with government incentives is you get a load of companies set up to cream off the money, then when the money stops so do they. These companies whilst in operation throw in the bare minimum of systems, and this is where the horror stories come in. They don't design then properly, they don't configure them properly. Then you end up with these daily mail stories of people taking out heat pumps to fit gas again. What scares me is social housing. If they start fitting heat pumps it'll likely go to contractors, and they will not be properly designing every system! Already there are heat pumps in some social housing where people complain they cost a fortune to run. It needs to be a building regulations requirement that every heat pump achieves a SCOP of 3 and above. Every heat pump should be notifiable, and for a certificate from building regs they need to prove its operating above 3.

Enjoying watching both your channels - especially liked Roger's video on the different sources of Heat (explained in simple terms) even though the theory was familiar, the practical applications to heating a home were of interest. Having looked into getting a heat pump for my flat, I rapidly came to the conclusion that I'd need to sort out the insulation & air-tightness first, and have gone for a cheap portable heat pump as a temporary replacement/supplement for my 40+ year (and still going strong) fan heater. Unfortunately, finding a builder with experience of internal wall insulation, using more eco-friendly methods than spray polystyrene, in a remote area, is proving difficult. Perhaps this is a set of training to be added to the Heat Geek's repertoire & supplier map?

It is good to see a reasoned informative debate. Historically, to produce 1 kW of electricity, you created twice as much co2 as producing 1 kW of energy from a gas boiler. Given that the percentage of electricity generated by renewable sources in more recent times, the emissions are pretty much even overall. I believe the primary goal should be to reduce first, improve the insulation standards to older properties and improve draught proofing, etc. By reducing energy consumption, you reduce emissions and costs and bring people out of fuel poverty. The potential issue with ASHP is that some installers don't budget in enough time and costs to fit and balance a boiler system, let alone a heat pump, one given the proposed volumes that the government is proposing.

(they will achieve it of course given exactly the right conditions but these conditions are met only about 20% of the time) The ASHP in full summer are perfect but the COP falling to sub 3 in winter makes the cost prohibitive and we use the gas and solar thermal in winter. If you told every new consumer to expect their energy bill to triple when switching from Gas/Electric to fully electric they would run a mile. My systems have now been looked over by 4 different sets of "experts/specialists and they all agree there is absolutely nothing wrong with the system (after changes were made) but not one of them dared to offer any alternative with any sort of overall efficiency guarantee.

Hi Roger, The reason your wife feels cold sometimes when the room temperature is the same is due to "black body radiation" (infra red). All objects, including people, radiate heat in proportion to its surface temperature and the temperature of adjacent spaces (eg outside). When the outside temperature is lower the black body radiation is increased and hence there is greater heat loss from the radiating body (your wife) so she feels colder. Maybe a better way to help with this would be use a small infra red heater directed at your wife rather than increasing the room temperature. A couple of good debates, thank you both.

Pardon my technical ignorance on this subject, but as I understand it, the heat pump itself extracts heat from the outside air, correct? So what if the outside unit was inside a glass box, like a green house? The box would trap the heat from the sun (when it's actually sunny here in the UK!) and the heat pump would then be working in a much warmer environment than simply being exposed to the elements. Wouldn't that make it run more efficiently and lower ones electric bills?

Fantastic discussion around this, I'm merely an IT geek/home owner and this has brought out a lot of information (some goes over my head, but not all!). The grants going to people who can already afford them is spot on, that the industries that are heavily involved in extracting the money from grants will likely disappear or will cowboy their way through installs (like a lot of solar). The future of electricity generation holds the key, nuclear was heavily demonised over the past 30 years, technology has been moving forward however thorium reactors have not been heavily developed because you can't "defend your country" with the waste and that is a crying shame. If and hopefully when fusion is ready, energy generation will be cheap enough that powering hydrogen generation plants will be low enough cost and co2 output will be such that replacing suitable gas boilers with an alternative will be laughable (I can dream); but until then well developed/planned/installed heat pumps are the short term answer for replacing the least efficient installations.

[@HeatGeek]

Powering hydrogen plants will give sub 70% efficient hydrogen generation to Power a 90% efficient boiler.. so 10kw in gives 6kw out. Using nuclear to power a heat pump and putting 10kw in gives 35kw out. It makes scaling not only practical, but possible
