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.
I love these collaborations with experts in different areas of house design, heating, insulating etc.
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. 🙂
so nice to see you guys working together.
Good to see the information sharing and learning between you two.
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 .
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.
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.
Indeed, and not forgetting the energy and environmental costs in producing and installing the equipment involved.

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.
@@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)?
Wow, lots going on, nice to see you two lads playing nicely, good info about the new products, and methods
never seen Skill Builder, not playing nice, only question ignored politician stile changing the subject, and answering that question instead 🙂
Thanks guys!
I love watching these videos, it shows neither of you are misleading anyone as the other person would challenge it.
It's great!
I love that you have both got together, it shows that knowledge and facts are king. I hope more people can learn from this.
When purchasing a good HiFi consider getting a Valve/Vacuum Tube Power Amp and that will get your room nice toasty.
Another great video. You guys are knocking it out of the park. Open minds and honesty. Thanks.
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.
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.
Viessman I do believe
All this new tech is great. But size appears to make it almost impossible to retro fit in most properties.
I have a 210L tank plus buffer's in the cupboard my oil boilers tank was in, zero lost space inside the house, could have moved to the loft and gained space. Ashp itself is about 300mm wider than the oil boiler was.
@tarkadahl1985 Thanks. Combi boiler in kitchen cupboard. Loft probably only answer.
Really think we should be pushing the solar panel shading that you've put on the front of the office, best case, it could avoid the need for air con, worst case it could partly power air con.
Needs to be accepted that this "look" is good for house fronts.
Never forget that a single panel plus micro microinveter provides useful power during daylight and will last about 15 years without maintenance
Is that baseball cap worn to gain thermal load and the reverse peak to aid cooling?
🤣🤣🤣
i'm super keen on that!
No this is good both of you together guys .now its worth watching
A lot of this gear is absolutely fascinating and I’m sure has its place . The biggest issue is most people couldn’t possibly afford such stuff in the near future as an alternative for a gas boiler. It will be interesting if technology can really save the planet or if in fact the future trash it creates will be tomorrow’s global issues.
The stuff you seeing in videos like this will eventually be mainstream and affordable. Who would have thought 10 - 15 years ago that the mobile phone would be universal in Africa enabling decades of technology to be skipped
Similar to the EV situation - the up front cost of both is well above what most of the population can afford - and for no immediate benefit to the individual.
Cold bringing through those box lintels at the end 😏🧱👍🏼
Hi great video. Can you share the name of the firm that makes the solar panels for the front door canopy?
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.
Boilers are meant to be "on all the time" and on/off heating is not good regardless of heat source.
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
@@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 🙂
@@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
@@njipods Thank you 🙂
Great vid, great to see
Hydrogen fuel cell. Utter craziness. Burn the natural gas in a boiler: it's the same emissions and much more efficient. It's also extremely complex and will break down. How much to repair? 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.
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. That’s what’s happening here, it’s just the engine is a fuel cell. Combined Heat and Power (CHP) is not a new idea, you’ll find it in most hotels.
Great video. The hydrogen fuel cell has been on my bucket list and we’re about to start our new build. U value is planned at 0.13 house will be timber frame, 305 sqm net internal, fuel cell or ASHP?
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.
10kW Arotherm, 25yr old half insulated house using original 15mm plus a few changed rads SCOP 400%. They work.
Solar energy is a technology 4 billion years old. Windmills were first used by the ancient greeks.
Hydrocarbon fuels are the current technology, with only nuclear capable of providing a more potent energy source.
very interesting Rodger having being a heating engineer for 40 yrs I am glad I am coming out need a science degree to do it now plus a large bank account
great content
@Skillbuilder, are the heat pumps utilising 'latent heat' transfer. Learnt from my aporentice days, R?
Still too state of the art for typical house or residential development the cost must be prohibitive for mid budget house developments.
I want one!
Forget expensive heat pumps, they are old tech now. Local areas to me had tests to send hydrogen down gas pipes. It works well.
Since 1982 I have been to the Alternative Technology Centre in Wales, they have been testing things like this for years.
Why not build a big hydrogen generator and feed that in to your boiler!
Good to see a Sunamp. Never seems to get much love. But must be some scenarios where it makes sense.
They use them in Orkney, huge amounts of excess wind so installed in heaps of houses. Turn on automatically rather than paying turbine owners to shut down. Free heat for houses when windy.
Where do you get the solar pv briese soleil mounts?
Yen Dai from EEE sorted us out, get in touch with him 👌
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.
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.
We have loads of similar stuff in our house, not the fuel cell CHP, but solar thermal, PV, heat pump, thermal stores etc and I can show you our gas and leccy bills are almost sweet FA in the summer and not a lot more in winter. Thanks for showing us the future, all we need now is a GOVT that doesn't have its head up its arse.
your bills are low because the rest of society is subsidising you, not because this technology is cheap.
@@bertRaven1 Sorry bert you are mistaken, we paid for all the kit ourselves without subsidy and self installed it so we actually give away lots of electricity for free, no feed in tarriff So actually I am subsidising you!
@@johnhaydon4055how much does your indoor winter clothing cost you?
This tech is nonsense,it works but not very well.
I have an oil fired boiler and a wood burner and my summer bills are naf all and winter not much more.
Carbon is necessary for plant growth.
@@pbysome I am sorry but our electricity and gas bills prove the tech works, my energy monitor shows we used 2.4kWhr from the grid, and it has been pretty much the same for six months. Thats for a 4 bed semi that is kept quite comfortable in the winter.
Doh, that should read, we used 2.4KWh from the grid LAST WEEK, sorry
Good to see you talking.
Never a problem talking, it is shutting up that is tricky
Do you use a heating management system to manage all these different system? and if so what is it?
THANKS ROGER>
Do they have a version powered by U235?
Is it just me that loves a combi boiler?
Combi boiler, cheapest to buy, fairly efficient, cheap to run, whats not to like.
@@tedbearfudge Also they heat your home even when it is cold
A "Combi" system is far better than a combi boiler.@@tedbearfudge
How much carbon is produced by making all those devices over the lifespan? (Solar PV, battery storage and EV driver here)
Pretty much everything green becomes carbon neutral within a few years. Windmills within a few months..
Yes, I wonder about that, and removal of existing systems.
I don't know about these particularly but RUclips Fully Charged show recently myth busted carbon debt of things like ev cars. They made an interesting point that the stats rarely incorporate things like the carbon produced by the fossil fuel production. Very good video.
@@JamesSymonsFTW I’ve also seen a lot about the distinct difficult / impossibility of recycling solar panels and turbines. Even a Green Party MP spoke out about the data! Im really not into all the carbon stuff but I don’t agree with companies selling stuff like Drs used to promote cigarettes
@@JamesSymonsFTW When it comes to cars, the best thing to do for most people is to keep what they have until it is no longer functional (or financially viable to repair), and only then replace with an EV. Anyone who is selling a functioning combustion engine vehicles to buy an EV are likely just adding to CO2 emissions (unless the rare case of very high mileage drivers using very old and inefficient cars).
The only way to truly reduce emissions is to buy less stuff (manufacture less stuff) but clearly no government of a consumer driven economy is going to put that message out to the public. So people will go on renewing the phone every two years and their EV every 3 years, thinking they're doing something good for the planet.
Really interesting video
Found this very interesting as we're soon to move into a bungalow (built in the 60s) and we've got to install a whole new heating system and I've absolutely no idea what to do. Still don't.
1. Establish your heat loss
2. Do everyhting you can to reduce the heat loss with insulation & possibly MHRV
3. Get a heat Geek approved installer to quote
Get a gas central heating. It will be warm
@@poorfordtransitowner1627 You're assuming that
1. He has mains gas
2. He's as short sighted as you
@@flatfoot it's a bungalow built in the sixties, bound to have mains gas! I jest, hopefully the OP will come back with more information. I don't think it would be short sighted to put in gas central heating. it will all depend on what they're doing to the property overall, if there are existing radiators etc and their budget. 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).
Get a combi boiler for well less than £1000. Compact, efficient, effective.
It's really good to see all these technologies. They might not be for everyone or indeed only a few. But it all takes time. I'm just against forcing people into so called green technologies and again so called green taxes. I also wonder about the materials and manufacturing of these products, not to mention longevity etc?
So good to see Roger there! I get the feeling Roger is seeing the other side of the coin now. But who knows he may still surprise u :D
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.
As for all this technology, it is not for the average home and therefore it doesnext to nothing to reduce CO2
@@SkillBuilder We need to stop Burning shit Rodger. I'm 33 with a 4 month old girl. Let's leave a planet worth living in for her. Your old look on the world that nothing really changes is wrong. To say the only option is to carry on burning shit as it's "not for the average home" is pitiful. You have such influence with this channel put your remaining years into pushing for a better cleaner world! (Sorry to bring your age into this, just something I would do with my remaining years) much love 😘
@jamesfagan69 it's OK you saying we need to stop burning shit, but if somethings doesn't work for most homes what good is it, the solution needs to fit every home to make a difference, how would you like it if you put 10k into the new clean solution to find that it doesn't work in your house and your all sat freezing but don't worry because your saving the planet.
@@jamesfagan69you are delusional! Co2 is food for plants! How many trees did you planted?!
@@jamesfagan69 Hi James .... interesting comments. Could I point you to Tom Nelson on RUclips and his guest Latimer Aldridge ( I think ?? and energy for dummies - no pun on my part ) - it covers base load generation and renewables vs base load. I won't make any more comments - but it's an interesting watch. I originally trained in Engineering.
Roger looked tangled up in the words, numbers, cables, pipes and boards. Just like an accountant who's trying to unravel a clever net of shell companies designed to hide money and identirties of the creators.
Anyone with a reasonable understanding of heat/energy can follow that
@@flatfoot I didn't say he didn't understand it. But he doesn't look relaxed as usual 🙂 As a consumer who must understand the bottom line, I'd be on high alert being offered that complicated and expensive stuff... The salesmen who sell that kind of stuff are rarely honest about the bottom line. (Don't you see how crooked the world is around us?) 15K upfront for a cabinet that turns gas into electricity? What? It _might_ be good, but what if it breaks? Or, like the guy said, if the govt decides to raise the price of gas, what am I gonna do? Your understanding of heat and energy won't help. I'm sure this kind of thoughts made Roger look not so relaxed.
It’s made by Viessmann, who make excellent conventional boilers too. There’s 100,000s of these units in Japan where they’re not scared by technology.
@@weekendwarrior3420 Hardly anyone can afford to buy one so I wouldn't worry about it. The only way these are getting installed as the norm is with large income tax increases and massive subsidies, otherwise not a chance of seeing them replace gas boilers before 2050.
@@RandomShart The point I was trying to make - I doubt these contraptions make economic sense, whether someone buys it on his own, or the govt seizes his money and buys it for him. Why 2050? Nobody can possibly know how it's gonna be in 2050 - maybe by then people will come to their senses and start building nuclear power plants...
Interesting on the hydrogen thermal unit, the latest news is Imperial has now got the hydrogen fuel cell down to $60-100 a KWh and is developing it for industrial use. Question for the team, Would a development version of that heat-electric thermal unit run on hydrogen gas, if they change from natural gas?
Following the carbon farce. $$$$
I LIVED AND WORKED IN GERNMAY ALL OVER
Legionella. Is that thing actually storing the water?
Lots of CHP’s installed in commercial plant rooms have never been switched on . They get specked for the design in order to gain planning permission. I have seen some that haven’t even been commissioned due to them being too expensive to run ie maintenance.
Nice one Adam :)
Hey, is that MY Kevin osbourne??
Sure is, how you doing @@HeatGeek
He said it all when he said this unit now out of date..so when it breaks someone will be looking to sell you another latest new thing…15k thanks but no thanks.
10 year manufacturer warranty, there’s thousands of these in Japan, I’m sure you’ll get the parts for at least 15 years.
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.
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.
@@robinbennett5994net zero is an impossible target to meet. It's beyond ridiculous. There would have to be net zero people.
Not difficult to work out that what we really need is twenty-five new nuclear power stations. The only tech you would need to heat your house would be a simple electric boiler. Anything else is nothing more than a gimmick.@@robinbennett5994
Actually the opposite happens. The deeper your nation's heating needs can modulate and the more electrified it is you can run that with cheaper energy.
look at those big puppy dog eyes! he wouldnt lie to anyone.
How much C02 is released making the H2 ?

the biggest threat to global warming is the widespread societal expectation of being entitled to wear light summer clothes inside, year round. In the 1960's and 1970's we wore extra layers in winter inside and enjoyed the season.
The past and the future meeting. I'll leave it to you to work out who is who😉.
I will stick with my Vaillant combi
It’s all becoming far too complicated for the normal person to make a decision on how to heat the house
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.
@@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.
@@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?
@@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.
@@Swwils The problem is not so much the efficiency in that scenario, as the ability to heat the house to a warm temperature. Heat pumps are unlikely to be able to heat an old and poorly insulated house, where a gas boiler will have no such problems. Not a lot of point in having great efficiency if the heat pump can't even crack 20 degrees C.
Imagine if the millions of solar panels, wind turbines and batteries we manufacture were stopped and instead the resources spent on nuclear power stations and electrified public transport. Clean energy without millions of tons of non recyclable waste in 20 years.
As long as we can store the spent nuclear fuel rods in your back garden. Fifty years ago we were promised virtually free nuclear electricity but that never happened. 😢
@@WanderingDutchman I'd rather a few tons of nuclear waste in my back yard that will sit there quietly until my great grand kids are old than millions of tons of pollutants that are free to roam IN THE AIR.
Gott to say that hydrogen unit would be something I would get. So surprised that they don't push them more. It sounds perfect for someone like me who's not ready to go full eco.
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?
AC Battery .. now there's thing!
I like the guy, no bull, this is where we are at the moment sadly. However, lose the hat and ripped jeans, it makes the pitch look a bit unconvincing. Customers want the WHOLE package.
Any more rips and you might see it 😂
Just a little correction for the co2 emissions. The data he said was for gas power stations only, and not the electricity grid as a whole which is alot less as it is mixed with renewables/nuclear.
The CO2 from nuclear is actually high, but it's embedded carbon in the building and decommissioning, not in the running.
@@iainathairydog I know, as is solar! But I'm talking about the carbon intensity of electricty produced per kW (from the video).
With carbon capture and storage it might be very low cO2 from gas fired generation. If it works! The pilots CCS in 2003 did not work well.
@@iainathairydog I don't think there is any agreed approach on full life emissions for power generation, so it's difficult to say whether nuclear is high emission or not. For instance, I doubt that wind and solar emissions take into account the associated emissions for the creation of the enormous battery storage facilities they need to ensure they can provide a stable power supply (mining minerals, transportation recycling cells etc). I would assume renewable is the lowest emissions and nuclear is the lowest emission from those power sources that are stable (with stable meaning they can ramp up supply to meet demand as it is required).

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.
@@SamDude-cu2jb CO2 levels on the ISS are allowed to reach 5000ppm - are you saying they are unable to 'think clearly' whilst working on the ISS?

Like electric cars, these things are toys for people who have the money in the first place and don't need to worry about fuel bills. The people who do worry are subsidising the people who don't through their energy bills and taxation. It's not fair or right. All for a problem that may or may not exist. Its a status symbol.

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. I know this is a quick you tube clip and maybe sitting down with an expert would make all clear but just now it is off putting bewilderment.
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 general and poor won't be able to afford these products
Like the poor can’t afford a/c in their cars these days?
Rog are you sold? Are you being courted mate?
Why would I use electricity to run a heat pump, when I can use electricity to run a room fan heater? £15000 vs £25?
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.
Imagine tring to fit that 1/2 a tun in your average house. £13k. Im sure the Chinese will supply the lithium we need to go broke.
Why is the young guy wearing a cap, especially back to front, ripped faded jeans,, takes the shine off the video..seems to know his stuff but I find it rude.
Roger is as good as ever👍👍
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.
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 ?
Is that18 Kwh throughout the day, or 18 Kw per day ? Big Big difference.
don't you mean "Is that 18 kW throughout the day, or 18 kWh per day ?"
@@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.
I’ll stick with Gas! Cheers 🥂
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.
" MIGHT BE A BIT LOUD FOR A KITCHEN "
It's as big as a lot of kitchens these days.
Please tell me why lithium batteries are used for houses, why not use AGM batteries ?
They can better handle multiple charge/discharge cycles. Problem is, the catch fire like all.the electric vehicles at the moment.
They are lighter per Ah, have a greater depth of discharge and much longer lifespan It's really a no brainer.
@@vic6820 internal combustion engine cars are more likely to catch fire than electric cars.
@@davek5839 Nonsense.
@@vic6820 Google it maybe? Don't rely on the Daily Mail.
The Hydrogen fuel cell sounds interesting
I don't think there is such a thing as "AC Battery" all batteries are DC
Sonnen specifically call their battery 10 an AC battery, i think it refers to how the battery is connected
Ac coupled / dc coupled
Not being on the tools but very interested in heating efficiently I love seeing this after some quite tense but adult discussions in previous Collab videos. Looking forward to the next one!
A 32 kW combi boiler producing hot water for 13 showers? What’s that, about 1.5 litres per minute each?
For a minute 😂
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.
"under current government guidelines"
There’s a tank in there.
So basically its a high flow combi, or an unvemted cylinder
Is that really an AC battery or is there and AC - DC converter and a stack of DC batteries?
I wonder - maybe there's a flywheel in there? Seems unlikely...
It'll be an inverter.
If the planet really is warming up what are we gonna need heating for anyway lol
Yes heat pumps work well on warm summer days! 😊 .
They also work in Norwegian winters, but the gutter press will have everyone believe they're useless
Am I understanding less carbon is produced to convert natural gas to electricity than taking it from the grid
Burning coal is the most efficient for generating electrical power at a power station burning gas is a lot less efficient substitute. But our leaders thought otherwise and closed the pits
looking on drax electric insights, says the average emissions for the last year was 153g/kWh, not the 900 he claimed
@@Puffball-ll1ly Coal is efficient? Revisit your sources. It's 34%. Gas is 40% Wind is 100%, kinda.
@@Puffball-ll1ly Huh? Reference please. And how do you express "efficiency"?
Yeah, I just challenged him on that. Looks like King Coal has been leaving some posters short of oxygen. Gas is preferable by an approx 50% as per efficiency of potential yield and lowered emissions, but it's still a dirty fuel.
some telling body language from roger there.. haha.
He's not convinced is he?
Very interesting and on the face of it a good idea to generate electricity from the fuel cell ( reformation process) and 15 KWhr s a day is about what I use in winter. These Vitovalor Japanese units have been around since 2016 and the manufacturer says only good for underfloor heating , not radiators.
The manufacturer also says the reduction in cO2 is only 50 %
The government have been considering plans for the gas companies to do the conversion from natural gas to hydrogen at street or district level then domestic users would not need to spend much as all.
No real data performance or maintenance cost/ fuel cell life / given by manufacturer.
Interesting but very expensive and not possible in new houses unless the Gov changes mind about gas burners
Hydrogen may still win the energy race as the problems with lithium batteries and EV charging continue to grow
Do you know where the H2 come's from ?
I just got some dilithium crystals instead, so much simpler.
You made the wrong investment Vibranium is far better!
"These are DC batteries".. aren't all batteries DC?
@skiddy - build a Passiv house then it will cost £300 a year to heat. Winner
How many people are able to work on these pieces of kit safely??? I'm convinced there will be a load of cowboys coming out of the woodwork claiming to be experts causing untold damage and danger.
So many products for the future of domestic use, come back in a year and i am sure it will have changed again .... interesting times ... #stopburningstuff
Sun is out... Yes power free of charge...
So the installations are free?
