This is a bit misleading, I have had 3 estate agents value my house and they all said the green stuff doesn’t really add anything. I would be interested to see any data to support your claim. Could you do a video to show the Scop octopus install get on average. Also a video to show how the full life costs of a heat pump is cheaper than a gas boiler. Thanks.
I don’t understand how, when the government has announced they are stopping cheap off peak electricity, that a heat pump can be viable. Gas costs about 5P/kWh and peak electricity is about 25p/kWh, it takes approximately the same energy to heat a unit mass of water with either energy source. It goes against the laws of physics that it can be cheaper. The only exception being if you have generated your own electricity for “free”using PV or wind.
Heatpumps can be over 300% efficient without breaking the laws of thermodynamics. They are not consuming electricity to produce heat they are using it to pump heat from the environment (ground/air/water) to your home. This doesn't break the law of thermodynamics. Your fridge for example will have a CoP of around 1.6 (160% efficient). I hope you now understand. There will be more in depth explanations a google search away.
@@russcraig1216 Thanks I looked and it’s essentially a fridge in reverse, but with the addition of a refrigerant to water heat exchanger. Every step in any system has inefficiencies, so I still struggle to accept that a complex system of exchange of states can be more efficiency than a single, direct transfer of energy. But I guess I must be wrong (or everyone using them has been fooled)! We did use one in a rental property about 10 years ago I had in Switzerland, the plant room was massive and took up the space of a normal UK kitchen. The room itself was overbearingly hot, suggesting a rather high inefficiency, so warm we used it to dry our laundry. I do remember our monthly electrical bill was 3 fold what I am paying now, but I was too busy at work to pay much attention.
@@yp77738yp77739 You seem to be very ignorant about this whole subject. I suspect you are watching dodgy youtubers who don't understand facts but enthusiastically push rumours and conspiracy theories. Here is how I see the points you raised. Heat pumps, as has been mentioned, move heat from outside water, ground or more commonly air to your heating system. You also get most of the energy you put in as well. It is not all good news as they need cooler water in the return so usually other upgrades like larger radiators are needed. Underfloor heating is ideal. Good insulation is needed to take advantage of off peak electricity. They usually have to run longer than a boiler would so not good if the hose is empty all day. Also they are noisy. Off peat electricity use is encouraged as it reduces peak loads which is where the grid struggles. It is likely to be used more not banned but I expect the price difference to reduce as EV takeup advances. I only use off peak electricity as I have a large battery for load shifting. A big upfront cost that will take 4 more years to break even. I could also use it to make money by selling power back for a profit at peak times. I don't have a heat pump yet as the payback time is too long and I despise the red tape around getting one installed. I want to install it myself and keep my gas boiler as a backup/booster. For £7500 I could install a very nice system but can only get a mediocre system fitted within the regulations. I have a 200 year old 6 bedroom house which needs a good system. I will probably end up making my own system out of used refrigeration equipment.
I would question the 16% - yes I know they need to promote this technology. My previous property had warm air heating and that put people off and yet it warmed the house quicker and much cheaper to run. To combat this my estate agent researched the warm air boiler and once she showed them my gas bills they became quite positive. I miss it. Some potential buyers were genuinely worried that the warm air boiler was a ASHP and that was a year ago.
Like EVs Heat Pumps are technically fantastic but not suitable for everyone. I live in a 60 year old semi-detatched house with good insulation. To swap over to a Heat Pump system the saving would take nearly 20 years to pay off the investment. If I was in a poorly insulated house with a boiler on its last legs or a house without central heating then it would be a different story.
Does that payback period include the savings in getting rid of gas altogether? The gas standing charge isn’t an insignificant cost. Every little helps.
@@st200ol Yes. Standing charge on gas is £108 per year for me. I would love the technology of a ground source heat pump but the cost of a system change, let alone the hassle of ripping up floor boards, etc means it's not a sensible move for the vast majority of people in the UK.
To give a counterpoint many historic buildings including here in Scotland are heat pump warmed. If they can do it in Denmark it can be done here. That doesn't mean that in your specific case it makes sense just that people shouldn't assume old means that heat pumps won't work.
I also live in a 60s semi. I have had a heat pump installed by Octopus in August. The install was very good. So far it heats water efficiently at no more cost than gas. I turned the heating on two days ago, so far so good. They are not for everyone because of physical space needed. As far as installation costs, with grant cheaper to install than a replacement gas boiler. Running costs, well that depends on your tariff and the relative cost of gas v electricity. I am expecting to save money. The heat pump is 3 to 5 times more efficient than a gas boiler. As you say not for everybody, and never will be, same for electric vehicles.
What’s the payback for all the money spent on this over complicated expense nonsense? What’s that point of removing a simple cheep to run efficient combi boiler? Would you spend £12-15 k of your own money on this?
Hi @russcraig Can't remember my original post I'm assuming it's cause I said gas is 4 times cheaper? . I understand how heat pumps work as an installer. I think the point I was trying to make was neat pumps are 3 -4 times cheaper to run than a gas boiler in terms of energy but the energy cost is the same in difference per KW price Ie gas is around 4 times cheaper per KW to run so it all balances out long term . Thanks for the reply 👍
I was quoted £7500 for a heat pump by Octopus. it may be more efficient than our oil boiler but I can but 3 oil boilers for the same price. Look forward to the prices coming down.
Everyone raves about heat pumps and yes they heat the house and work in the winter and not that noisy. But they are very expensive, complicated and difficult to get repaired. 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. Would you pay £15k for a heat pump that will in reality only save approximately £200 a year. Ps, will need massive radiators and a small room to house all the kit.
Yes. Living in an “all electric” house with no gas boiler or wet central heating system why would I want to put ugly pipes and radiators around the interior of my house?
People that believe the COP figures and savings from these companies probably believe the mileage range quoted from EV manufacturers. Even IF a heat pump system saved me 33% of my electricity bill, it would take 25 years to pay back for the initial instillation of the system.
At 3:51, does the average annual saving of £220 include savings from disconnecting from the gas network (no longer paying standing charge), or is this due to the higher efficiency of heat pumps compared to gas boilers?
But beware, there are no tools for the end user to measure the efficiency, and even now I’m getting at best a cop of 2. Which means , because elec is about 4 times more expensive than gas my costs are at least twice as high as with gas.

Some major errors and omissions in this video. 1. The grant is only available for a whole house system. People that have to use multiple heating sources can't apply. 2. If you are one of those, like me, in the countryside without gas or oil you will not have radiators so can not use, (this kind of,) heat pump as they use your rad's even if a few need replacing with larger ones. 3.Those who have the most expensive heating - storage heaters - can't use this system as it requires radiators. 4. Heat pumps are very bad in deep winter, but good at other times. (see below) I speak from experience, not figures that show 'average over a year' 5. The more practical form of heat pump, other than for new builds, is to install air to air heat pumps otherwise know as air conditioners. I find they work very well in all but deep winter when I do have to use the storage heaters but that is normally only a few weeks a year and I still put one air con unit on if the temp' pops up a little midday. The only bad things about air conditioners are that there is no grant at all for them - they are thought of as a luxury rather than what they are - very good heaters, even if they do need a backup heater. and the installation will cost the same as the units themselves. 2 years ago I paid £3,200 for 2 x 4kw (heating) units and slightly over half of that was installation which took two men one day. I do recommend these especially if you have PV, you get free heating for a good part of the year and even taking into account needing a secondary heater, (in my case a few mobile oil filled electric rad's and a wood burner) are well worth buying PV + Air con is an excellent match.
What he doesn’t mention is that at temperatures of 5 degrees or less the heat pumps efficiency drops and it uses more electricity. This will means there will be no cost advantage and as the pump has to work harder the noise levels increase. All the space that will be required to house all the cylinders and tanks will cause problems in modern homes that took the cylinders out when they were encouraged to install condensing boilers that don’t need storage. The particular design of the Octopus heat pump might have a problem if there is heavy snow as the fan faces up.
Also electricity is around 4 times more expensive than gas , and I can pretty much guarantee all radiators will need changing to accommodate the lower working temps. I am a heating engineer and I have recently installed a heat pump to my own property so I can be a guinea pig for my customers.
@@waynebeal1152we needed to replace about half our radiators to obtain a decent flow temperature. We could have replaced fewer by using a higher flow temperature. People may like Nicholas Raimo's video on his Octopus pump install.
