The first thing that needs doing is to insulate homes properly. We need to have more grants available for people to put in closed cell foam insulation. Make the homes as air tight as possible and ventilate them with HRV systems. It will be much cheaper in the long run. After we have that setup we install solar battery systems and heat pumps. We have the potential to take most of every home off grid if we do this correctly. IMHO - building regs are still not up to scratch and leave a lot to be desired.

Hey, agree with you on a lot of stuff regarding heat pumps. You often give balanced and nuanced responses. That said in my experience the removal of gas utility connections isn’t necessarily going to materialise as a cost saving in new builds. We had 200 homes where we were following fabric first, MVHR and all electric design that were made commercially unviable due to electrical grid reinforcement costs. So it isn’t that simple unfortunately.

The MCS approved installer spent a good deal of time at the property doing the calcs and sizing radiators. Pump worked fine and we were fairly happy with it (probably because we didn’t have high expectations), yet I don’t think it ever reached a cop of 200%.

It is expensive to run and gives nothing back. I have turned off the heating and replaced it with 3 Everett stoves, which are really good. Although the hot water is set to 24hrs it is always cold, so we have to repeatedly use the boost button (up to 3 times) to heat water for washing up etc. I have really struggled to find anyone to offer a service, the original installers have gone. I have recently contacted a company I saw on a recommendation of our local face book page who wants £400 plus vat and extra if the glycol needs topping up. Luckily I have a gas Aga (aims programmable) which help to heat the property; gas central heating would be preferable but with the cost to convert and net zero agenda this is not a possibility.

@@ralph4371 I haven't heard of low volume radiators but ASHPs need a certain volume of water in the system for defrosting. At outdoor temperatures of 2-3 degrees, especially if there is fog, the heat pump will ice up and need to go into deicing mode. For that it can and should use the heat held in the water in the system to turn the ice into water. The more water in the system the less the temperature will drop and of course the water will have been heated up at a COP of 3 or thereabouts. You will also get less temperature variability when the heat pump goes into hot water mode which might last an hour or so. So for my money I would go for big radiators holding a lot of water. UFH is ok for tiled kitchen floors but I doubt there is real benefit in rooms with carpets. I am not a great fan of hard floors and noisy rooms, give me a carpet any day. And if you have got the insulation right or it is a modern home the radiator outputs aren't going to be that big? My lounge, carpeted in a 1980s built house has 3 radiators type 22 60x60 which don't hold too much water, 3 or 4 litres each? Look at the spec of Mitsubishi heat pumps and you will see they need 40 litres of water in the system or more depending on size. And unlike gas/oil boilers you will be running your heat pump low and long. Mine consumes only 1.5 kWh when the outside temp is 5-8 degrees to heat 18 radiators and 40 m2 of ufh.

@@Geyer128I think it's unlikely that you would have spare PV generated electricity if running a heat pump 24/7 in winter but it would certainly pay to direct any to heating the DHW before exporting it to the grid. I still think it should be used to heat the water through the heat pump not using an immersion or backup heater.

Sadly less than 50% of Scottish homes are suitable for heat pumps. Effectively installing anything built before 1970 is simply too difficult/expensive. You really need to examine the housing stock outside the southeast a little more.

Good presentation of the costs associated with heat pumps to the consumer, the government and the planet. I am already signed up for a Heat Geek assured heat pump installation and in order to get the BUS grant had to have a new EPC done to reflect recent cavity wall insulation and upgraded loft insulation.

My EPC assessor told me NOT to get a new EPC done after the installation because a heat pump will make the EPC score worse!

These grand plans the government has really are unfundable by both the general public and the government itself. The government already taxes us to the hilt with services being continually downsized so where it all goes is a mystery. We are now having to pay for our green waste collection. The inexorable closing down of public transport whilst a green agenda is promoted beggars belief; 1 in 4 services have disappeared in a decade.

When looked at in the round the use of hydrogen for domestic heating is a non-starter. There are several reasons for this: 1) green hydrogen is enormously expensive to produce and requires vast quantities of renewable energy (note that blue hydrogen can never be zero carbon and unfortunately our government has committed billions to blue hydrogen production - a very costly mistake we are all paying for in our electricity bills); 2) the thermodynamics of hydrogen generation and distribution render it too expensive for large scale domestic heating.

Fully agree on this. Small scale production of hydrogen from electrolysis and solar is possible but then you are generating electricity to produce a gas to then produce electricity or heat. Fuel cells require platinum to get any kind of decent energy. Gas is so much more dangerous then liquid fuel storage. Its molecular size cause issues leakage. There are pilot programs in Scotland 300 house ran off hydrogen. If hydrogen is ever going to work we would need mini/sub generator stations with district heating. Individual hydrogen boilers in each house in my opinion is not the way to do it.

I've heard comments about community heating on your channel before but I'm not convinced that a row of terrace houses will get that without significantly more council / government help. Which doesn't seem to be a topic of discussion from either. And I'd have thought that community heating basically means someone loses their home so it can be converted into a boiler room of sorts.

For us in Northeast USA near Boston/Rhode Island we also have a unique problem that makes the heat pumps solo heating your home not a very good idea. They increased our winter electric rates to 30 cents a kWh. But our maine/vermont cousins have very cheap electric so they didnt notice this issue (back when maine was being used as the marketing research done on heat pumps). Flipside, alot of houses in the northeast do not have AC systems (most have window ACs) so the electric cost for cooling is usually higher here. So heat pumps help cool the house more economically and efficiently than those window AC units. But what is ending up is that heat pump users don't have natural gas to fall back on, and oils prices were much worse than the heat pumps. Instead alot of us are looking into wood stoves, which are getting a 30% tax credit for any purchased in 2022-2040. So the better heating/cooling setup is to buy/cut a couple of cords of wood and manage a 2k square foot wood stove that can burn for 30+ hours after about an hour of heating up the stove waiting for the burn mechanism to engage.

Excellent bit on the upcoming costs from carbon charges if we don't act in a concerted fashion.

Recent updates to Building Regs Part L in June 2023 in the UK state new boiler installations must come with a maximum flow temp of 55 degrees. This means ALL new boiler installs will likely come with upsizing rads and (in horrible case scenarios) upsizing all the primary pipework in the house :( which means new boilers no longer cost 2.5k, as flow temps for most houses are around 75 degrees. Still, I know two heating engineers who have installed new boilers since June and didn't touch the emitters or pipework, flow temp still the same as it was before. Completely illegal... might be years before it starts biting installers in the backside, but it's building regs after all.

Will hydrogen ever be viable for domestic heating? As I understand it to make green hydrogen you take electricity and split water into hydrogen and oxygen, which I have heard is only about 65% efficient. The hydrogen is then piped to homes and burnt in boilers to release heat at around 90% efficiency. So only 58% of the energy used to make the hydrogen actually gets converted to useable heat at the other end. Why not cut out hydrogen and just supply electricity directly to homes to power electric boilers or heat pumps? Assume 10% losses for the grid the still means 90% of the energy available to heat or run a heat pump. Hydrogen seems like a dead end for home heating.

For a new build it surely is a no brainer, but I would not opt for an air sourced heat pump if I had the choice. For the replacement of a functioning central heating system on natural gas, the situation is completely different and I seriously doubt the validity of the reductions you mentioned. I agree with the deduction of the price difference in case you actually need to replace the existing installation, but if it is still functional this is not a valid deduction. Also the replacement of the copper cylinder is not something inherent to a every heating installation. We do not have a separate cylinder for warm water and simply do not need to replace it. I also don't understand how you can get to a deduction by moving things around or upgrading your radiators. Looks to me that this will only generate a higher cost. How about maintenance cost? A heat pump is a lot more complex than a simple gas installation, meaning that a lot of parts can break and moving parts will inherently results in wear, lubricant usage etc...... My own installation (natural gas and a HR+ condensing Junkers boiler with maintenance contract) is now 10 years old and the total maintenance and repair cost over this period comes down to 175€/year, including the mandatory inspections, repairs and replacement parts. Prior to my retirement we installed an air sourced heat pump for the heating and cooling of our office building, which had a volume of about 4 times the volume of my home and the yearly maintenance cost alone was more than 2000€ (repairs not included). I have no idea of the cost for a home installation, but if this is proportional to the volume or the output, it's an additional cost of more than 300€/year. To put this in perspective, my yearly bill for gas at home was, until last year, between 800 and 950 €/year. (Currently it's about triple and I expect that we will never see the low prices again thanks to our political leaders.) If the existing installation was properly calculated, the radiators will for certain be undersized and need to be replaced. It's even possible that you also need to replace the piping and adapt the electric wiring to cope with the new system. The value of your property is very subjective and you will only get that benefit when you sell your home. Most people do not buy or build their home with the intention to sell it and will remain in the same house for the rest of their live. If your installation is 10 years or older at the time you put your house on the market, the buyer will take in account that he will eventually need to replace it, no matter if it's on gas or a heat pump. Also the life expectancy of such an installation needs to be taken in consideration. The average life expectancy of a heat pump installation is comparable with a gas boiler, but the replacement cost is a lot higher. A high end gas boiler cost between 1200 and 2000 € while a heat pump is 3 to 4 times more expensive. Subsidies (lower in my country than in the UK) may reduce the cost of a heat pump by a few thousand €'s but it still remains way more expensive than a gas boiler. If you're forced to go for an air sourced heat pump, there is also the matter of noise. A friend of mine changed from a gas heater to a heat pump and had to move the outside unit further away from the house due to the annoying sound the thing makes and it turned out that the losses due to the longer distance were too high to heat his house properly in winter.

I know that not all properties will be like mine, but a significant number are like this. It would make sense to open up the BUS for air to air heat pumps - and you get the benefit of air conditioning at the same time (I have MS which is a health condition made worse with heat so this is a great upside for me - many disabled people are in a similar situation and I believe there's scope for separate incentives to provide disabled people with air conditioning and heating at the same time). Domestic hot water heating is still an issue - I wish there was a heat pump cylinder system that could be connected to the same outdoor unit as the room heating units, but you can get stand alone heat pump water cylinders that are relatively cheap. I've gotten quotes for both kinds of system and found this split air to air/water cylinder system will be cheaper for us to install even without the BUS scheme.

If it takes 9000kw of electricity to heat our space right now with resistive heating - it'll be around 3000kw of electricity with a heat pump.

There are no radiators or pipes for them, just electric storage heaters. AC is generally simpler to install and has the benefit of cooling which for me with my heat sensitive medical condition is really useful. What makes it madness to pursue this if it is cheaper and provides more benefit? We are looking at those heat pump water heater cylinders - you don't need to have them operate within the conditioned envelope of the house, most of them have standard sized fittings for air vents so you can run an input and output vent to circulate air from outside through the unit so you're not using the hot air you've created inside the house to heat water. The main issue I have with them is that they take up more space than the existing immersion tank.

repayment times of 25 years (your shortest projection is crazy ) I'm 57 and probably won't live that long, over the years I have replaced / removed many heat pumps with most not lasting 10 years some under 6/7years real running costs in my customers homes, yes I have a heating business too with average 20 staff and 35 year's experience, were over 30% more with many people who are installing now also having to pay from 10 to 30,000 for insulation required for almost 75% of our housing stock without which very few homes can be heated to the temperatures we are used to with the HPs. I admire your attempt to inform but even manufactures that I talk to state at present people will see a running cost increase of 20 to 25% against a condensing gas boiler doing the same job and they are on the conservative side. as for cost in future replacements boiler straight swap 2,000 ish needs replaced in 20 years hp 4,000ish but replaced twice in 20 years so yet another 6000 on top of original conversion costs region 15000 not taking into account most homes with a good electric shower and induction hob are already being fitted with switch gear to prevent both being on at once due to domestic property electricity supplies new upgraded supplies required again for our existing housing stock it will take more than 13 years to up the power generation for future car charging let alone this this is a major factor in the use of hydrogen boilers running alongside gas till 2050 at least according to the power suppliers.

I was looking at a Sanden, then a read the reviews on product reviews and there are a huge number of people having control board/electrical failures and Sanden blaming them on “power surges” with no evidence. Sounds more likely to be poor design or poor component selection as it’s wide spread. If Sanden’s warranty on the controller was longer or they covered was appears a design failure I’d consider them. If a Sanden costs 1.5k+ more than a similar size budget heat pump, then that’s longer before it pays itself off, if it doesn’t fail first.

As always I enjoy your content. I agree with a large proportion of your points. However I do have a few issues. (1) "offsetting" the cost of a heat pump into the house price increase/decrease feels a little spurious for most people. There will come a time when it factors into the decision but probably NOT until around 2035 when the law changes (assuming there isn't a U-turn). (2) Cost of installing gas to buildings, in fairness that's a valid argument however new builds should all be built with 3 phase electric supplies to be able to adequately provide the houses with bidirectional electricity supply - which will increase the cost - probably still a saving but less than £30k. (3) Third there is a huge amount of housing stock that doesn't have adequate electricity supply into the property. Either on 60A supplies or looped supply. Who will ensure that the DNO's carry out the work required in a timely manner? They still haven't completed the "smart meter" installation that was originally due to be completed by 2020 but got pushed until 2025! (4) Again housing stock issues e.g. Terraced houses, typically have limited space at the rear with electric supply to the front of the house. As far as I am aware, it is not permitted to install ASHP onto the front of many houses so where would you install them? That being the case I can see a terrible future where "Electric Boilers" are installed by those on low incomes, landlords who want to comply with regulations on the cheap and, sadly, disreputable councils (of which there are many!). (5) EPC's if you speak to the 'experts' about how an EPC is calculated its mostly a calculation based on the size of your rooms and the fabric of the building. Yes there are some % points for using LED bulbs etc but the weighting for things such as Solar PV at best move you up the scale by 1 point but they always give an estimate of the cost of doing this. I had an EPC done when selling my house it cost me £50 and the guy was present for 30 mins maybe tops (the estate agent wanted £75 and would have used the same person but charged me £25 for the pleasure). How much work doe you think is involved for £50? The biggest issue that faces the industry is the government. Doesn't matter who is in power they are only interested in monetary policy in 4 year stints of governance. Solar PV has been in place for over 25 years now and it still isn't LAW that ALL new builds should have Solar PV installed. We still have an overly complicated process with DNO's being able to charge or outright refuse to permit larger Solar PV installations and with a bigger draw on local electric distribution hubs that is likely to get worse as the phase balancing on transformers gets more difficult. Lets provide some context: The government bailed out the banks in 2008. When they sold the shares in Lloyds TSB Group they lost money on the deal. How does that work?? We should have recouped our costs at the minimum or remained shareholders until the paid dividends offset the cost to the taxpayer. Why did they permit the banks, who all took public money to keep them afloat, to continue to pay bonuses whilst they were effectively shareholders. As someone further down has mentioned we subsidize the Oil and Gas industry to the tune of billions of pounds per year, why? The rail networks have been subsidised by the public for the last 40years (or more). So why, when we are paying something like 30-40% per ticket price are we giving them money to allow them to pay bonuses to management? When COVID loans to keep them afloat were made the Scottish government chose to re-nationalise them. The English government had the exact same opportunity but instead decided to give them low or zero rate loans AND permit them to continue to "make profit" and pay bonuses in the following years. I heard on the radio today the a large number of councils across the UK have suspended Summer Holiday meal vouchers for low income families. We are talking about £15 per week per child for the lowest income families in England (Wales has maintained the payments across all regions). Some, but not all, councils are offering activities and meal groups as an alternative. How is that even permissible when inflation is up 13% and energy will have tripled in cost come October. Sorry got off topic there a little but I think you get the gist.

Super useful. What id like to learn about is the steps needed toward a heat pump install. My house is a converted barn / stables. The boiler is ok for now but will need replacing in 5yrs or so. Im upgrading parts of the house myself which means insulating as we go. But what else does heat pump ready mean? What rad upgrades are needed? Can I use the existing pipes? A video on how to prepare for a future heat pump install would be super useful. Or at least how to not make a future install harder.

I’ve got that same problem, 3 foot thick granite walls with no thermal bridging. I can only add insulation to the ceilings. Also a converted Barn so was never designed to be lived in. There are also no heat geeks Installers in my area (Cornwall) Current quotes are saying it will be a 2k running cost. We have no mains gas and are using oil central heating. Is a heat pump going to work on my property, my current EPC is 60 with a max potential of 79 It seems a similar cost to our current oil prices?

Can a property be made heat pump ready over a period of time, so that 15k is spread out over the course of say 10 years? It seems to me like a lot of the improvement would benefit a boiler install anyway, with the insulation and larger radiators allowing you to reduce flow temperatures? Then when the time comes you get the heat pump in. Hope they’ve invented self washing clothes by then so you’ve got space for the cylinder?

It could, but the more you increase the efficiency of a house the less energy you need, and the lower the RoI of a ASHP system is. For new small builds finding space for a cylinder is a bit of a pain, for a lot of older houses that already have an existing water tank upgrading to a more efficient modern one is far easier.

Heat from Electric is 5 times higher in the USA than natural gas. The average "delivered"(please look at your bill) per KHW is around .20. There is 29.3 KHW per 1000,000 BTU's. 1 delivered CCF is less than 1 dollar. The efficiency on a new boiler is about 83% to 92% depending on water temp. Average around 85% which works out to approximately $4.98 for electric vs 1 dollar for Natural gas.

A quick Google says average electric is $0.166 for electricity in Oct 22 and gas is $0.046. Ad a new gas boiler is 85% efficienct you'll only need a cop of 3.

@@HeatGeek They do not include delivery and taxes. 1 ccf of gas is about 100k BTU or 29.3KWH of electric. All in for gas delivered, taxes, meter charge is less than $1. Even if all in for electric is .16 as your Google says, that is 4.69 x .85= $3.98 which is 4 assuming electric was %100 converted. It's not. This is a lot of assumption on the electric side and in your scenario a $600 heating bill goes to $2400. The average in the US is 5 to 7 times higher. New York state is mandating everyone switches by 2030. This is total insanity.

When comparing costs I was expecting to see something like "And if you already planned on adding an aircon, that price can be deducted from the heatpump installation, since modern heatpumps pumps heats in both directions"

Help! I've been offered an Air Source Heat Pump with all new radiators, and new electric meter and PV Solar panels via Warmer Homes Scotland Scheme, for free, as we are low income and IN fuel poverty NOW. Sounds great but I'm so worried that the house will get cold and my electricity costs will spiral. I'm rural and have Oil Heating for the home and to heat our water. So Oil costs are spiralling. I'm soo nervous going ahead with this..advise please..Lisa

And sadly all what your local MP will do is to ignore it..and keep focusing on filing its own purse 😕

Your arguments make sense, if, and ONLY if, there was sufficient manufacturing capacity for retro-fits on all houses AND there were enough engineers to carry out the retrofitting?

Insulate the f#%k out of your house and totally reduce the cost of heating your house whatever heating method you use in a nutshell!

If you already have a hydronic heating system and install a monoblock HT heat-pump, you can get rid of the gas and all the associated costs on your gas bill. Monoblocks are really cheap to install because there are only 2 water lines and electrical service. No HVAC technician needed.

Strongly disagree. You can do that but you will experience scops of 1.5 - 2 (150 -200% efficient). To get your system designed and installed properly will give 3 to 5 scops. (300 to 500).. and pay back much more in thr long run

Octopus gave me a quote I would have to pay only 3000£...not convinced... especially not sure would work in my home 😔 I have 3.2 kWh solar with 6.5 kWh battery already but it does absolutely minimum at winter time.

Great video, but some inaccuracies in the information about the gas grid. Local distribution network is largely plasti and pipes in homes are copper. Both are good for hydrogen. Also, the local electricity network WILL need upgrading if every home in the street moves to a heat pump. Decarbonising existing homes is one of the most difficult challenges to achieving net zero, so it’s great to see a sensible debate on the subject!

You come home from holiday and your heat pump is gone! Its been nicked haha.

Best heat pump ??new build 2800sqf under floor heating ?
