Heat Geek Tech Tour ~ The Future of Heating?

[@spacetime3]

This is what we need in the country, professionals speaking honestly to each other so we can have proper debate without letting the media and lobbies control the narrative. Thank you for your collaboration.

[@Czechbound]

I love these collaborations with experts in different areas of house design, heating, insulating etc.

[@terryjimfletcher]

Agree - it's important to answer common "oh but" comments from people with different views - just like when Roger said "but you should run an ASHP intermittently" and for this installation that's not what was happening - the "intermittency" was for more than 4 hours, not the 10 mins on 15 mins off, 10 mins on intermittency that shouldn't happen on a HP installation. 🙂

All this to solve a problem that does not exist , and ha 15 grand is peanuts . Come Rodger most people are struggling to find the money to replace a standard boiler , that unfortunately is unlikely to last as long as the one there replacing . I seriously worry about this drive for technology that’s doesn’t take into account the real world of the average consumer .

[@edc1569]

The UKs gas reserves are depleting, people won’t allow fracking, gas prices are going to become higher and more volatile. One day in the past coal was the cheap way to heat your home, now it’s a luxury.

[@edc1569]

A standard heat pump install to replace a boiler is well under 10k for many modest properties, with government subsidies it brings it down to a price comparable to a new boiler.

[@davidscott3292]

Indeed, and not forgetting the energy and environmental costs in producing and installing the equipment involved.

[@SkillBuilder]

Di2m441 I don't see this as a mainstream product and these guys are just experimenting with a lot of high end kit. We had a long debate about all this so there was no need to go back over all that when they took me for a look around. The viewers can make up their minds.

[@ricos1497]

@@davidscott3292 I don't think anybody is advising people to rip out a working boiler and replace (unless it's really old), it's an end of life/new boiler needed job. Are the environmental costs of producing and installing a heat pump significantly different to a new gas boiler (with emphasis on significant)?

[@geoffaries]

I applaud the heat geeks for their approach to the alternative tech. I'm a bit of an "inspector gadget" now retired from the commercial heating world. I've been following the progress, sometimes lack of progress, of all the alternative heating systems, ASHP late 1980's, ECE CHP units aka Stirling Engines, micro chp single cylinder gas engine and then Fuel Cell boilers. Although I love the tech I've never found them to have a decent RoI, which is what most commercial customers are interested in. The fuel cell boilers were being trialled by BG, I think it was called Ceres? This is the first domestic unit that I've seen available via the trade, who is the manufacturer? As much as I love the tech, I still dont see any financial point in replacing a mains gas bokker with any of the above.

[@0tispunkm3y3r]

Ceres is correct. Those FC boilers are still running I believe. They're now based up in Nuneaton at MIRA. They make some good sense I think. Having the ability to generate heat and power on the property. It's a neat idea in my book, but would need fleshing out properly.

Educational as always when you both appear. The chat in the kitchen about heat source pumps and cycling was useful. The put off for me considering them was, it seemed, that they have to be on all the time and I'd only need them of less than 6 months with my PV etc. Food for thought so thanks again.

[@Swwils]

Boilers are meant to be "on all the time" and on/off heating is not good regardless of heat source.

[@njipods]

the reason they say leave it on is because people leave the heat pump off. come home. house is freezing. they turn on the pump and it takes hours to heat up and then they moan. honestly you can turn them on and off as much as you want really. just understand that they might take a while to heat up. these days though its only the really really old systems that are manual everything should already been on multi day timers and thermostats

[@dbat3291]

@@njipods Thanks both. I guess I'm thinking more seasonal being the concern. I'm only looking at this as a homeowner so will ask silly questions like, what do you do with the heating in the summer if you have a pump? I have Solar panels which also heat the water so would not have a need for heating or hot water from the pump for 6 months of the year. When Adam indicates they use the pump more or less as a back up to the other systems it got me thinking. I think Roger also hesitated a bit then. On the Heat Geek site, as Adam always says there isn't a straight Yes/No answer. In one scenario where the occupier might be at work all week and often out at the weekends it would be wasteful but doesn't go into it any deeper on that page. It gives me some homework 🙂

[@njipods]

​@@dbat3291if you don't need it for 6 months you switch it of for 6 months lol. Yes it could be that if your just pooping into the house for a day a week then running the heating all week would be wasteful. At work we have heat pumps and they where not set up right. Monday mornings in winter where freeeeeezing cold because they where only set to come on at the same time as work started. All I had to do was get them to come on a few hours earlier on Mondays and it was fixed. You just have to give them a little more time to get going is all

Credit to you Roger for remaining open-minded. I have to admit I was also skeptical to start with over the claimed efficiency of heat pumps; but I've changed my mind. Like solar panels and wind energy, they're the way of the future just as gas central heating was in the 1970s onwards. Technology moves forwards regardless of what the more conservative among us believe.

This was recorded at the same time as the debate. I have always tried to see the other side of any argument and I am always happy to be persuaded. I have never thought it was a weakness to change your mind but my original views on heat pumps for the masses still stand. If you look at the thousands of comments that we have on that first heat pump video you will see that many support my claims. I have also talked to many installers who have taken heat pumps out and put gas boilers back in.

The fuel cell is intriguing,impressive setup there. Glad Roger is liasing with them,i gave them a bit of a hard time when they were slagging roger about his heat pump opinions,felt it was pretty disrespectful. Only issue i have is the minute renewables is mentioned the price seems to skyrocket.

[@ambassadorfromreality1125]

Renewables are fundamentally cheap. The initiL costs are frightening. These have to be converted to long term affordable finance so that there is little difference to current costs. Renewables are stable and cheap. There will never be oil and gas spikes when a country goes rogue. I have had solar pv for 12 years , an electric car for 8 both work as predicted. Looking back it was worth it. Looking forward it looks brilliant. This should be available to everyone and will be in time. In the 70s only 30 percent of homes had central heating. We now are close to all homes but it took time. The second world war was only finished paying for a few years ago. I don't think anybody fighting it was thinking of the cost but they did it to everybody's benefit.

Im woundering - when you use the hot water from the solar collection would this not keep the heat up in the circulation water, so the effecience would still be good when the heat pump kicks inn again? Also the heat pump in it self does stops to defrost sometimes, maybe add some extra heat from the collectors at that time as well?

Your points one and two on the first post are certainly worth paying attention to, and I'd add that if you can't afford a heat pump or whatever, then perhaps to think about the transition that might occur in 10-15 years' time otherwise. Maybe consult your heating engineer to see if there are things you can do now that might save ripping up in a decade's time (underfloor heating or whatever).

OH, but it's warrantied (as long as it's "serviced"). He also lets slip that the generation of electricity in a power station is much more inefficent and polluting than using a gas boiler. PS there's no such thing as "free energy". Good to see Heat Geek is generating plenty of profit. Well done, Roger.

[@edc1569]

Presuming your property uses electricity why not run some of the gas in an engine, generate some electricity and use the waste heat for space/domestic heating.

A lot of modern heating tech takes advantage of off-peak pricing, but I can't help feeling as more and more of us store more and more 'off peak' energy that the difference in price will narrow? The long-term winter answer for anyone (almost all of us) who can't run a chimney has to be cheaper grid energy. Then again, that depends on politics... 'german discounters' will have skiwear in the lucky aisle again soon.

[@robinbennett5994]

I don't think so. At the moment half our electricity comes from gas, which can be throttled down at night. If that's replaced with wind, it will keep running at full power and there will be a lot more spare power than there is at the moment. The exact hours will probably change, and we might see more agile tariffs, but more renewables can only mean more variation. In the long run, to reach net-zero, we will need enough extra electricity for all transport and heating and industry. That's 3-4 times as much as we make at the moment. That's such a big change that there's bound to be some instability before it settles down.

[@Swwils]

Why. The heat pump is 200% efficient at worst, 500% at best. Your gas boiler will be 60% at worst 92% at best. If you have a crap house that needs lots of heat, it's even more obvious which one you should have. It's very simple.

[@paul756uk2]

@@Swwils Things are never that simple. If you have a crap house that needs lots of heat, the very last thing that will be any good is a heat pump. Good insulation is the one thing that you need for a heat pump to even begin to work. They're not that good in the UK's climate and even worse with radiators. They can work fine in self builds with high levels of insulation and underfloor heating where lower temperatures are needed. Also, electricity prices are at least 4 times the cost of gas per kWh and that's the very first consideration when looking at options.Having said that I think they can work well in the right circumstances. Just that the UK climate and housing stock generally aren't the right ones.

[@Swwils]

@@paul756uk2 you are wrong. If your house uses alot of heat than the efficiency of the source is even more important than a well insulated house. Unless you wish to break physics?

[@paul756uk2]

@@Swwils of course it is but heat pumps don't work like 'any heat source'. It's not a question of efficiency. It's whether or not that heat source can supply the heat required or rather, overcome the heat losses which is the basis of any heating system. In most cases heat pumps will fail to do that in a standard UK house. Firstly their efficiency gets worse the lower the temperature because there's less heat to extract. In many cases the outside unit has to be heated for it to work. Secondly, they struggle to raise the temperatures sufficiently to run a radiator system and they struggle to heat hot water to a useable temperature. In almost every case, if you rip out a gas boiler and replace it with a heat pump, the energy bill will sky rocket and the house won't heat to the desired temperature. Despite being efficient to the extent that you get more heat out in KW than you put in, you have all the above plus 4 times the energy cost of gas. As I said, heat pumps work better in bespoke designed houses with higher rates of insulation and the lower temperatures of heat required with underfloor heating. Your view is purely theoretical. Real world conditions are very different. Heat pumps are fine in more temperate climates where winters are warmer and summers are hot and where you can use them in the form of air conditioning units in reverse. These units can also be suitable for commercial premises in the uk as they're heating the air, not water but the efficiency drops off considerably in very cold weather. I've had them installed in places where I worked for the simple reason that it was used primarily as air conditioning so it made sense to fit heat pumps that can work in reverse. If I was building a bespoke house, I would certainly consider a heat pump because it would be designed into the house from the start but the figures would have to be heavily scrutinised They simply won't work properly in the majority of UK houses. Many power stations are gas fired so you're burning gas to turn it into heat, converting it to electricity then using that electricity to turn it back into heat. There are losses at every stage.

[@johnacky]

I heat my 200 sq/m, 150 year old cottage with an oil boiler. It's very well insulated and my oil/ electric bill is less than £150 a month. Would love to upgrade but can't justify the initial outlay. Even with grants it's still way over my budget.

You'll be surprised how ready for full eco you might be. They always say "you can't run a heat pump if you're not fully insulated or you'll pay a lot of money to be cold", but the truth is you're paying a lot of money to be cold with a gas boiler as well. Unless you really have no insulation at all (which wouldn't be smart with current energy prices, some insulation measures pay themselves back in one or two years), you probably don't need 20kW of heating power. What you do need to run a heat pump is the same as what you need to make a modern gas boiler actually run more efficient than an old one: piping and radiators/underfloor that can deliver the power you're producing at low flow temperatures. But hey, who's stopping you from getting that hydrogen solution?

@@redshift3 No, I mean't it as stated. If it were producing 18 KWh throughout the day, then that would signify it could produce 18 KW per hour for every hour of the day. If it produced 18 KW per day, that would only be one twenty forth of the previous.

@@johnbewick6357 18kW (power) throughout a (12 hour day) would be 216kWh (= 18kW x 12 hours, energy = power x time), 18kWh (energy) throughout a day is just 18kWh (energy)

Sounds like it's a daily total. I think he said it generates 750W of power continually. That's 18kWh a day.

The future of heating is making things as insanely complicated as possible and make the rich richer whilst making us poorer! I get it. When my combi breaks I'll be getting a 200 litre tank with immersion heaters. Super cheap up front and simple to maintain and 20 year lifespan easily.

[@timhancock6626]

As a recently retired heating engineer I think there is a lot of truth in what you say. Where are the simple solutions? Individual roomstat controlled electric panel convectors are cheap to buy and install and could be a better solution for some than a heat pump. Who maintains all this stuff at an affordable price ?

Whatever happened to the KISS principle? This is what happened to domestic entertainment equipment - the 'simple' designs of yesteryear did the job and an industry was built up around them to repair and maintain them. Then 'modern consumerism' i.e. unnecessary complication entered the fray and now everything is 'disposable' - as these heaters and fuel cells will become. Madness - on the basis of lies told about CO2.

I can easily understand the workings and economics of a gas boiler or electric heater but I listened to this barrage of alternative bits of kit with loads of figures and did not come away with any grasp of what I could do in my house.

If you’re on the gas grid I wouldn’t worry about it until your boiler is up for renewal? Unless you have solar.

The gas hydrogen fuel cell, may save on the carbon/methane/Nox emissions, compared to those produced at the gas power plant, but looking further back the chain, through leaking pipelines, extraction, fossil power used in the extraction/manufacturing process, burn off, exploration and infrastructure required etc, anything gas related is extremely carbon/methane/Nox etc intensive. The hydrogen fuel cell is an inefficient, expensive waste of time. Despite this, much respect for what you do as a business and educator. Great channel. Also watch Skill Builder too.

Why would I use electricity to run a heat pump, when I can use electricity to run a room fan heater? £15000 vs £25?

[@trojanhawrs4613]

A normal heater is somewhere between 90 and 100% efficient. It uses all of the electricity to generate heat. This is fine, and generally slightly more efficient than a gas boiler - but given gas is a hell of a lot cheaper per kWh, it makes a lot more sense to burn gas. Heat pumps take the heat from the outside air and move it into the house - because its not directly heating, only rearranging what's there already, it gets the same amount of heat for a fraction of the electricity used. As mentioned, 350% average efficiency is expected.

A 32 kW combi boiler producing hot water for 13 showers? What’s that, about 1.5 litres per minute each?

[@jamesjulian]

For a minute 😂

[@eliotmansfield]

I think there was some confusing talk. From a quick google, it’s a standard unvented tank (220L) and the boiler is a condensing boiler (not combi boiler) that can assist the chp when needed. 13 showers claim is nothing to do with the performance of the unit - as with all unvented systems it’s pressure and flow from your mains.

[@paul756uk2]

"under current government guidelines"

Any time carbon is mentioned with regards anything, I turn off. First its carbon dioxide. Second, carbon dioxide is good for the planet, it makes it greener which is better for crops. Thirdly humans generate only a small proportion of all CO2 generated. Fourthly the effect of CO2 on global temperatures is not linear, it lessens off as the CO2 increases. And lastly the global temperatures are only recovering from a cold period, it'll go back to levels felt in Roman times.
