Are you in the UK? I’m really impressed with your energy bill. You’re in effect running the car for free!

For those who have one, does it maintain the heat constantly even in hot temperatures? The south of England is getting hotter all the time and I know they were originally sold as both heating and air con.

I've heard mixed reviews. My cousin bought a house with one, and didn't get on with it. One friend loves their heat pump. Another likes it but says it cost more to run than previous oil fired boiler (they do have an older house so probably not as well insulated).

Someone in our street has one, you can hear the pump from the road, I definitely wouldn't want that constant noise in my garden.

It's air to air that are both heating and air-conditioning. Air source heat pumps cannot cool. I have a vailliant air source heat pump fitted by heat geeks. I love it the house never went below 18 C during the day last winter and yet it was cheaper than the year before when my gas boiler only kept house at 15C. My house has is not particularly well insulated either, 1930s ex council.

We’ve just done our first winter with one and are really pleased. House stays a consistent temperature, much more pleasant than previous winters. No issues at all with hot water as the tank is decent size. No noise issues either but all our stuff is in the garage and outside so away from bedrooms, but even during the day we don’t really hear it.
we are in a new build though that is well insulated. We also have solar panels which massively helps with running costs. Fuel bills have halved but that’s because of those, and we no longer have gas connected.

Ours doesn’t do cooling, we got it with octopus and with the government grant. To get the air con too up are looking at a lot more money.

Same here! Our cheapest week was £3.70! DH is somewhat obsessed with ensuring the panels are all set to charge at the optimal time.

I logged in and double checked the figures. The most expensive months (two) it’s now just over £300 a month, so more like £10-11 a day. It used to be higher until we switched to a heat pump tariff but we had to wait for a smart meter to be able to do that. We don’t have gas so that’s the total cost for cooking, washing machine and tumble dryer use, not just the heating.

The house hasn’t been below 18 degrees since we moved in, and we keep the downstairs room at around 21 as WFH means we’re quite sedentary. Bedrooms we keep cooler.

It’s a 6 bedroom house with several extensions, so a lot of external walls. Its
about £50 a month cheaper to heat than our previous smaller terraced house.

That’s a different type of system. That would be air to air, where you have air vents and ducting through the house. I don’t think those set ups are eligible for the govt grant?

ASHP heat water running either through radiators or under-floor heating so there’s no cooling mechanism.

Our’s will be a 4 bed detached house,built in 2018,well insulated.family of 5 with 3 children.I m just dreading how much will b electricity bill in December- March with ASHP🤔

And do you see a time when electricity will be cheaper than it is now?

We have had our ashp for about 3 years now. We are in a 4 bed detached bungalow so very long and not much passive heating. We have an EV no gas so solely rely on electricity. Our yearly bill is £1100 and half of that is from January and December.
does the house have solar panels? As you might get the FiT if you do

ha in an ideal world yes because more renewables and investment in nuclear.

I can however see gas prices increasing and with heat pumps being a third more efficient gas prices don't have to go up much in comparison to electric before if becomes more expensive.

Near me they make electricity from a small scale gas generator. Only half the week.

Gas prices will impact electric prices.

Sounds like it’ll be fine. Our house is bigger than that and not well-insulated (the EPC when we bought had a lot of “assumed” on it about insulation which we are very sure isn’t there)!

The hot water is so much better than with a combi boiler too. We’ve never run out, it comes through quicker than waiting for the combi to heat it up and water pressure isn’t affected by running appliances at the same time as the shower.

@Flimingo
The property needs to be well insulated.
What is the EPC rating? Is it a newish build?

House EPC rating is “B”.The only factor pulling me back is that figure of “10-15 £/day”😳

We’re in. 4 bed detached house. As I said had heat pump installed in December. We’re in Scotland so gets pretty cold, but the heat pump kept the house warm.
December and January bills were about £150 a month - which included charging for 2 EVs. Certainly cheaper than when we were paying for gas and electric

Well we are supposed to be going through a nation wide decarbonisation programme, but a lot of places (council run buildings etc) while they can get a grant for the works, can't afford the extra running cost.

Can we turn the heating off from the pump through summer months and turn it on just before start of winter(November)?

You don't need to turn it off through the Summer, you just set the thermostat so it never kicks in.

I can give you my average daily costs through winter. This is for all electric use not just ashp, so heating, hot water, tv, lights, washing machine, dishwasher, dryer etc.
Oct- £4
Nov- £5.50
Dec- £6.90
Jan- £8.40
Feb- £6.90
Mar- £4.20
We use the dishwasher and dryer a lot as well.
I don't think it's bad personally and much less than we previously spent on oil.

You could but easier just to use the thermostat. Ours is one thermostat per room. It’ll only come on when the temperature drops below whatever temp you’ve set for the room. Ours doesn’t come on (other than heating water) during the summer months.

we don’t turn out heat pump off, but the thermostat means it doesn’t run when it’s 16 degrees or more
think that’s a pretty common way to set them up
so at the moment ours is only really running a bit at night and for an hour in the afternoon to top up the hot water
