Heat Pumps: anyone have one/thought about it?

I don’t think the take up is actually that high though. People who rent can’t get a heat pump and I’d imagine most landlords aren’t too bothered about it , if they have a working boiler , why would they bother?

The fact that the energy companies are heavily advertising heat pumps shows that they are desperate to do the installations.
 
I'm not sure on the numbers of heat pump installs. I was seriously considering one earlier this year. I had a quote from Octopus for a Daikin. It was around £4500 after the grant. I would have needed 7 radiator changes. I love idea of having a warm house all the time as people have described in this thread. I despise the idea of being freezing in the day and when the boiler comes on you end up being too hot. I know you can set the temp so it stays at 18 for e.g. but I imagine that would be expensive. My issue is I don't have solar or batteries. My Ideal boiler is only 3 years old with 7 years left on the warranty so it was a tough buy in to move to a heat pump.

If they go ahead and drop the grant it will kill the industry. For those who have heat pumps they may end up finding it harder to get someone in to fix/service. For those looking to buy one why would they want to drop a whole load of money.
 
I managed to get my heat pump for free.

£7500 grant

£2000 cashback from Barclays mortgage

£500 selling boiler and few radiators.

British Gas price matching a very keen quote from a local who did not really fill me with confidence.

It’s also crazy cheap to run - especially over night on 7p.

Do your homework on how to run it (low and slow) and it’s a no-brainer.

But do you have batteries and solar panels ?

Not yet, solar next when bifacial perovskite panels are easier to find, then eventually, battery - but they seem to keep getting better / cheaper - and also EV with V2H should be coming - in which case smaller battery needed (if at all). HP was the right thing to do now, in terms of grants, tech availability and cost.
 
I hope there isn’t a u turn with beat pumps like diesel cars. If the grants goes then heat pumps would have to drastically match the price of a boiler.

A boiler is around 2k. A heat pump is 12k. So it’s obvious that people would stay with boilers with that comparison.

No, a heat pump is around 3.5k.


It’s the 3 guys for 5 days to re-plumb everything where most of the money goes. Also all the expansion vessels, valves, pipe, new cylinder, electrical kit.
 
That heat pump is £3.5k, need a bigger one, add considerably more, need a tank, most will add another thousand or so.

Add the labour, and other bits and you are getting up there.

Most gas I used in a day, looks like 101 kWh on 4th January this year, this seems a bit of an outlier and I was probably testing running the heating all day or something, flow temperature was around 45c by the looks of it, out doors it was just above zero.

More common to have 70 to 80 kwh on the worst days.

To live in a well insulated house, I'm very jealous :D

Total for Jan 2025 was 6200kWh which is bang on 200kWh daily average.

I have some gnd floor insulation to get to at some point (need to tunnel through X2 dwarf walls), which will help a bit, along with some skirting/floor interface sealing to do.

But my heat loss for a peak winter's day is circa 12.5-13kW, so a tall HP would be the order of the day (like a Vaillant or Veisseman). Cost would probably be 15-20k at a guess (before grant).

Just looked and a 13kW Vitocal 222-A with DHW cylinder, installation kit, trace heating kit and other bits is £11k for parts.........

If my Gloworm boiler dies a new one is £700 + install in the same spot and I already have the thermostat, wiring centre and weather comp kit, so a HP ROI would be awful.

Ok I have a modern 4 bedroom detached house . Average size, not overly big.
Is my electric bill likely to rocket with a heat pump on say with Octopus ? In simple terms my energy bill according to my smart meter is usually about £8 a day on average during the winter months.That’s gas and electricity.

Think £15 per day during the cold winter months and £2 per day during the summer. Unless you have solar or batteries in which case it will be less in the summer and the winter.

No way a heat pump costs that much to run. Mine isn't using £2 even now. In the summer it hardly does anything at all, it spends about half hour a day heating water and that is it so about 12p on a price cap as mine caps out at 1600w. Even full tilt all day it'd cap out at just over £10, and i think i'd have to open all my windows at that.

In the winter, of course it does, depending on the size of the pump. Maybe you keep your house cold but say 80kWH on a cold cold day plus your house’s regular electricity use plus standing charge.

Cost 54p(ish) to run ours yesterday, that’s 2 x 15 minute showers, the days hot water, and heating holding the house at 21degrees-ish

Last year on a cold feb day we used 15kw to get a similar result - with 7kw of that at 7p - so 49p overnight, £2.50 - £3 da, so on a cold day, heat cost us £3.50….

If the OAT is above 11 degrees or so it costs pretty much nothing. If the sun is shining the windows heat the house. I had a good few days like that last week where I spent about £2. Yesterday the temperature was 3 degrees here and a very different story.
