It is a bit strange that people want to know the "return on investment" of a heat pump, but not a gas boiler. I guess since its marketed as "renewable heat" it goes in the same mental compartment as something like solar panels - which have a rather more obvious financial consequence. But unlike solar panels - HPs do something that is nessecary in a home- keeping it warm. Which presumably you dont mind paying for.

I didn't fit my Heat pump for financial reasons I did it for environmental reasons. We are warmer and more comfortable with all rooms heated 22/7. Despite that our heating bills have plummeted mainly because we are on a time of use tariff which is as cheap as gas and we are running at over 400% efficiency. We have a battery which we charge overnight at 7p/Kwh and run through the day on that plus whatever the solar panels add. So while fitting a geat pump wasnt done for the money we are saving shedloads, I havent done an ROI because, 1 I dont care and 2 with volatile energy prices its all guesswork anyway

I chose a heat pump to help climate change. As a battery owner I can use octopus intelligent at 7 p so if my smart meter is working there is also a cost saving. Thanks Andrew Scotland . I also removed my gas meter so another saving.

If the UK is to adopt heat pumps nationwide, we need upgrade price parity and parity in running costs as a minimum. The general public will not switch to a heat pumps just because its better for the environment. We may want to do it even if it hits us a bit in the walet, but most won't. Heat Pumps are nothing shiny to show off. There is no upside to easily promote except payback. More comfortable heating is hard to sell. It's similar for EVs when you don't have a drive. There is no benefit only Extra cost and inconvenience. Another real hard sell.

Sadly historical pricing increases on Natural Gas vs Electricity - are in favour of Nat Gas (if you exclude Post Putin/Ukraine) - so Nat Gas prices increased avg by 2% per year where electricity increased by 5% per year. So if you calculate your expense in 10 years for the heat pump it will be a LOT more expensive than Nat Gas. In 10 years that would mean you pay 22% more for Nat Gas - and 63% more for electricity per kWh vs today. So a 10 year future price of £0.073 for gas and .. £0.424 per kWh of electricity. (based on your stated pricing) If the UK had a strategy for electricity that was based on Nuclear power - we could probably maintain a low electricity price. But the current race to the wind and sun - guarantees - like Denmark and Germany - that UK will have increasingly excessive high electricity price increases. The ONLY system people should consider if they are not climate alarmist fanatics - are hybrid heat pump and gas. Then you have the CHOICE and the best of both worlds.

mine was free :)

You’ll be valuing the investment more during the (probably) several energy crises over the next 25 years. I think of it more as insurance than investment. Ripple’s 1st project members have recovered more than 50% of their initial investment. The timing was great for them but it inflated expectations for the other projects.

We can’t afford to make the choice.

If you need to replace your boiler you can also deduct about £2500 from the cost as the investment is the additional cost for the one off transition to a heat pump. If you want new rads and to get rid of an old fashioned open tank system there are other costs to deduct too. We paid £6000 after a grant of £5000 so if done today would have cost £3500 but a new boiler would have been £2500 fitted plus we have 13 new radiators (not rusty like our old ones) and a pressurised hot water system to replace a dodgy pumped system. I am getting an sCOP of around 4.0 for heat and 2.9 for DHW as tweaking my weather compensation (based on reading s form open energy monitor rather than the heat pump) which is good as Octopus originally quoted 3.4 and 1.7 respectively. Very happy with the move away from gas. Keep the videos coming.

Hi tom just wanted if I can to get your view. We had a heat pump fitted by global energy in sept 2024. It has a weather compensation system that varys according to the outdoor temp. This system can be navigated and adjusted by the company at their end. I recently rang them to ask could they check over the settings. They did and assured me its set at the most efficient. Its set at Upper AT heat 15 degrees. Lower AT heat 5 degrees. Upper WT heat 55 degrees Lower WT heat 34 degrees. Water temp 48 degrees. We run the heat pump 24/7 set room temp at 20 degrees. 21 degrees from 5.30 pm to 10pm. We are using on average 20 kw per day we are all electric with no solar panels. My question is with the experience you have obtained. Do you think that amount of usage is right. Which will only increase now as the weather gets colder. Thanks peter

My C&H was keeping us warm up here in Maine all the way down to -17 degrees F. Just make sure you do your research and get one equipped with an "Arctic Kit"

I've been watching your videos about heat pumps several times now Tom, we're just buying our first house and I'm getting a heat pump installed as soon as possible. I'm not massively concerned about the financial return because I know that won't happen until I have solar panels and a battery fitted, but gaining some independence from energy companies and the effects of crazy world leaders is reward enough.

There is several factors: - people are scared of change or do not yet see it as a reliable or proven technology. - Government involvement put people on the defensive. (Take evs for an example) - Someone who has a perfectly good working boiler, think quite rightly they are replacing something which doesn't require to be replaced so there should be a pay back on an investment. ( Whether this is environmental or financial) - People who have a broken boiler and do not have a lot of spare capital and have been quoted for a new boiler 1.5k and 4.5k for a heatpump, they will look at can the afford it, will the switch to heat pump save me the money I had to get a loan for. If they were quote nearly the same the switch for those without the spare capital would upgrade to a heat pump. Before anyone says octopus will install it for 500 quid maybe for some but they quoted me 4.5k and i will not be getting a heat pump until our boiler breaks or is showing signs of failure. As 4.5k is a big investment for me and most people, maybe when a remortgage is up I will go with a supplier that gives green incentives and the get one.

I’m speaking to Octopus at the moment about a heat pump and your thoughts are a welcome distraction from other channels solely focused on the minutiae of ROI. I’ve also been speaking to someone on another channel about the merit of combining a heat pump with a battery and getting rid of gas altogether. On balance, I have a concern that has nothing to do with cost and more to do with what I view as a disadvantage, that is the idea of the heating being on for 24 hours. I envisage a serious effect on my sleep through being far to hot through the night. The idea of 24 hour heat strikes me as being unhealthy. Am I the only one who thinks this way?

Our choice for a heat pump was based on it being slightly more expensive than replacing the gas boiler and being better for the environment. In practice it has been cheaper to run and the lower temperature radiators provide a nicer heat. The biggest problem is the mother-in-law thinks the heating isn't on because the radiators feel luke warm...

Part of the reason for people talking about payback times so much is that there is absolutely no argument for the environmental comparison, heat pumps always use far less carbon. Some people are looking for anything to criticize heat pumps on, and making payback an issue is one of the few lines they have. Companies like Octopus can make installing a heat pump much cheaper, their prices for installation are very good, okay the installations may not be absolutely top-notch, but they are reasonable and are part of the way to ramp up installs to the level we need. My house is so much more comfortable than it was with a gas boiler, even if I wasn't concerned about climate change the extra comfort alone would be enough. That detail isn't made enough, most people seem to think a heat pump equals a cold house.

We installed for emmisions reduction. We got the old 5k grant. But it will be break even in around 12 years. But it's very odd to make these calculations on today's prices. Assuming things will be the same in the future is misleading. As you say the levies are likely to reduce and close the gas electric gap. A punt I was happy to take.

Just had a quote for one, so interested in the answer!

This is my 2nd winter with a heat pump. No solar, no battery. I have my setback temp at 18°c and target of 20°c to 21°c. I pay £130 a month and currently on a fixed tariff from eon next which is cheaper per unit than the price cap. I have my heat pump on schedules, 7:30am to 11am and then 17:30 to 11pm. Not sure if this is the right thing to be doing, but there's no big fluctuations in the temperature. And if I do feel it when it's out of schedule running then I click up the thermostat a degree or 2. Then it just runs when it needs to.

Valuable insights into a subject I'm only now looking into. Thank you very much for relaying your experiences.

What are you paid for promoting Ripple as went to their site and strikes me as scam. They require a down payment no date when it will commence to pay back just pay to register an interest. Are you part of this malarkey? Hope you are insured for all costs your misinformation may cause.

Heat pumps run on electricity and electricity also comes from nuclear power stations and fossil fuels. I've bought some oil filled radiators which also run on electricity and installed an Immersion heater in my hot water tank which i can control via my mobile phone to regulate the water temperature. My house has nine foot ceilings and I can easily get to my comfortable level of twenty degress c in forty minutes. It's a delongi Dragon 4 2.5w ten years guarentee manual timer. So I think I'm using electricity and you're using electricity , what's the difference?My rads cost £136 each for 2.5KW. I've drained my radiatiors I can put furniture where I want to and my rad where i want to. I also have hot water, So my point is I'm as enviromtaly freindly say you are with way less cost. Immersion element and timer £50 or less rads at £190 or less per room, so if you want to think you're saving the planet good luck to you. You could also put a jumper on at times. You've been brainwased by the tel Iie vision my friend.

Really interesting, hadn't thought much about local grid capacity upgrades needing to precede demand

Just a had a 6kw aira heat pump installed yesterday with all radiators replaced with bigger ones. DNO request now pending for a 6kw solar system. Also have an ev so will be looking to investigate best tarrif options

You don’t talk much about capex or opex only fuel cost that’s only part of the story. Capex at £13k is more than double gas boiler thus the cost over ten years is higher and then servicing cost and repairs? Need to bring that into equation

I'm happy that you're happy with the setup. It's a very helpful video and thank you for goinng into detail about the costs. I don't want to sound negative but £196 cheaper p/y to run a heatpump vs a very efficient boiler is practically no difference at all. And you have to jump through all these hoops to make sure you have the right tariff from the right supplier, pulling electricity at the right time, with the right inverters and you have a hugely significant initial cost outlay. Installing solar to bring your cost down doesn't work without a large battery install and all the associated electronics and installation costs. You'e looking at £20K for heatpump installation plus all associated costs, upgrading all your radiators and plumbing, plus the solar install with battery and all the extras needed. That's a hell of a lot of money to just lower your costs a very small amount per year - that'll take a decade to claw back. I love the idea of using a heat pump / solar / battery / solar water heating etc...but far prefer the convenience of having a good gas boiler providing heat on demand and endless hot water without having to think about it. There's also the fact that it's nice to have a bit of variation in the house temperature, a constant 19-21 C is boring! A bit chilly sometimes and roasting hot at other times is fine by me :) I also love the wood burner for the kind of wrap-around heat that radiators can't supply. The last thing to consider is the very annoying noise (model and location dependent) that the heatpump fans produce. A neighbour recently had one installed and I can hear the humming outisde all day. I can't imagine entire neighbourhoods of houses running these 24/7. If I was building a new house, I'd be tempted but the attraction of retrofitting houses under the guise that it saves money, only really makes sense if you have about £20k to invest into it and plan of staying in the house for 10+ years. That's assuming that the price of electricity doesn't sky rocket if / when we go through some tough times ahead. Here we are, giving grants to try and lower carbon emissions meanwhile in the US they are about to revert to "drill baby, drill" times and ditch the EPA directives over anything related to carbon emissions! What a mess. Rant over :)

Hi, how much was supply and fit? How can it be integrate with the current gas boiler system and unvented hot water tank? Can it also be used in combination with solar?

The grid needs seriously upgrading to be able to handle the huge swings in power and massive increases in demand as transport and heat is electrified. The grid cannot handle this and people will be denied power, because the grid cannot flow it or because on windless and calm days there is not enough power generated. Further there is no practical way to store enough power for long-duration wind and solar droughts. These can last for 10 to 20 days. You cannot practically or economically afford to make enough battery storage for this and hydrogen production and storage is so inefficient and lossy that that isn't practical either. It is not possible for all intents and purposes. WATCH: Gerard Holland lays out the staggering cost of renewable energy at ARC Australia kzbin.info/www/bejne/qYPLf4KsZrqiaq8 As for the mineral mining and impact of all this on the economy and climate that is madness too! There is not enough mining capacity, refining capacity or manufacturing capacity to do this. You have to burn so much coal, oil and gas to make all this stuff that you are polluting far more than just carrying on with fossil fuels and you destroy the planet and your economy and the lives of your citizens in doing so. It is diabolical! See "The Unsustainable Green Transition" | Simon Michaux kzbin.info/www/bejne/pqjQqpqhmdR6ncU and "Energy Transition" with Mark Mills kzbin.info/www/bejne/qJjPY6J6osSHq7s explain why it is not possible, not practical and does more harm than good for the environment. You cannot mine that much materials, minerals and metals, it creates a system which has negative entropy (ie you put more cash and energy in every time you have to make it, repair it or replace it, than it gives back in its life time). It is a very stupid and bad idea. This is before you get into the fact that the whole endeavor of reducing human carbon emissions is a big scam. The whole greenhouse theory ignores that most of the change in atmospheric CO2 is natural, of the CO2 that humans are emitting most is from constructing all these solar panels, wind turbines, batteries and electricity transmission transformers and that since the emission bands which CO2 covers are already saturated and most energy is transported via convection to the upper atmosphere before emissions means that it really is not the cause of warming at the surface of the planet! All in all build our economy, mine/drill fossil fuels and make human lives better. The degrowth, impoverishment, hurt humans and hurt the planet policies of Net Zero have to be stopped for moral, environmental and economic reasons.

Free program put mine in only bee ayear and no heat. No one can help woth repairs, wish tjey never came out.....

I can't believe how bad this video is, long, boring, excessively detail and unhelpful.

This is so much detail without much clarity.

Everyone raves about heat pumps and yes they heat the house and work in the winter . Everyone who has one installed reels of great cop figures and how warm it is and how much better than a combi boiler ect, but the question that is never answered is what is the payback? Same as solar! When do you get free electricity? Never get the answer. Ps 19 degrees c inside is not toasty!

Electricity is more expensive per unit in the uk than Gas, so even though heat pumps highly efficient, the cost of running them is still higher, especially using them during very cold periods 🤦🏼‍♀️

Is it your pronunciation or I am hearin kilo hours?😂😂😂 kWh is kilowatt-hour

We've just had a Mitsubishi Ecodan heat pump installed in our 1950s Home last week. Struggling to get to grips with how to control the temperature correctly, as it seems to go either really hot or completely cold instead of a nice steady heat. I'm a bit crap with understanding how these things work. You seem to know your stuff!

Pointless video because they become inefficient at -10. My biggest problem is with them being outside, exposed to the UK weather permanently, no device with metal parts survives that for long. I'm sure after 10 years you need to replace it or the parts & labour would've cost you the price of a new one, whereas my gas boiler is now 25 years old and I've just needed to replace the PCB and the ignition wire.

This is a great video, thank you. It also highlights a problem a lot of people are going to have. Which is that a lot, if not the majority, of people won't understand how to improve the efficiency of their heat pump or simply don't want to fiddle with the settings. Meaning their experience is unlikely to be a good one. The other issue is the dynamic pricing. Once everyone starts to charge their EVs and/or use their heat pumps during those currently cheap periods, those won't be cheap periods anymore.

Interesting stuff! What model is your Vaillant? I note the aroTHERM Plus use R290 for the refrigerant, and as such seem to have stricter requirements for installation, notably with regards clearances to establish a protected zone. Further - I note building regulations state an ASHP must not to be installed within 1 metre of any property boundary. Is the wall to the right of the pump not a boundary wall, and what about the wall to the rear of the unit, is that a boundary wall with a neighbouring property? Thanks!

Q. what about noise? Is it intrusive in the summer? Also what was the typical room temperature?

a meter and a half from the pump is 48, so while I am considering one heat pump near the fence, I have used the apple watch as well and it is 48 background noise.. fingers crossed my neighbours won't hate me..

Great video Tom, thanks. You’ve just made my mind up to invest🎉

Thanks for the video - what temperature do you heat your house at?

had one fitted last week i hate it the house is now cold its caused so much stress i want it removed but what can you do

Just started to look at heat pumps and just have 2 questions. Once your on the heat pumps did you you have your gas supply switched off and if so do you still have to pay for gas as a standing charge. Secondly once everyone is on heat, how will the government claw back the lost revenue, increase the price of the electricity supply 🤔
