High KW Air Source Heat Pump options
Hi, I've a largeish renovated property (320sqm) which is well insulated, has wet underfloor heating down stairs and radiators upstairs. It has an Oil boilder at present. I've had ASHP suppliers around who look nervous suggesting stardard ASHP at around the 12kw to 16kw or suggesting hybrid systems that keep the oil boiler…

New ASHP and HIVE app.
We have our new ASHP in, being commissioned tomorrow. The Heating Engineer handed me a HIVE HUB today, if I want to use it. I’m very keen as I love technology and previously had a NEST with our oil central heating. So, I’m trying to register an account with HIVE ready for when it’s all working. But I have fallen at the…

Grunfos central heating pump
Pump stuck after being left off. Stripped it down then cleaned and eased the seized impeller so thought all was a goer. However, on switching on - nothing. What can cause this? Any suggestions? Does it have a capacitor or internal fuse. I checked windings for continuity and all seemed ok. Baffling.

Buying oil heated house - check suitability for heat pump
Hi, we've had an offer accepted on a property that has an oil heating system. Our offer considered the cost of installing a heat pump should the oil system need replacing after 2025 (it has been recently refurbed).

Heating not coming on with air source heat pump
Hi all, looking for some advice. We have just had a Grant Heat Pump installed. The only issue we have is the heating is not coming on as scheduled. The water cycle takes precedence, of course, but even when there is not hot water demand the heating will not kick in. The only way we can get the heating on is to either turn…

Solar Panels and Heat Pump fitted but savings not as suggested.
We recently received a grant under the eco4 scheme to have solar panels and a heat pump fitted. At the initial assessment we were told that the 12 solar panels would pretty much provide us with free electricity during daylight hours, during the summer months when we don't have the heating on. During the winter it should…

Grant for heat pump to replace home with storage heaters
Is there a grant available to fit an air source heat pump in a home that has no gas supply and is heated by storage heaters only. The house is a large bungalow and was built in the 1990's. All I see re government grants is boiler replacement, but I don't have a boiler and am not on any benefits. Like the idea of fitting a…

Thermal store for heat pump?
So I guess this means some kind of hot water tank? If say you've got an EV, you can charge that car between 12am and 5am for 7.5p/kWh In that same time, there's nothing stopping you from also charging up your home batteries + your hot water tank which means you only really need a COP of like 2 or so to be cheaper than gas…

Heat pump dryer - condensation problem
So finally managed to buy out first-ever dryer and we went for a Heat Pump dryer as they are more economical. Drying the clothes is ok. However, the dryer seems to fill the laundry room with moist air and we are getting condensation everywhere in the room. The whole system is supposed to be sealed so that the water ends up…

Heat pumps - COP
So I've seen from numerous places that the COP of ASHPs has got continually better ie: from a max COP of 2 or 2.5 a decade ago, to about 5 now. There's obviously seasonal variations I've not however seen the same said about a GSHP. Is it because that ASHPs are merely catching up to GSHPs in terms of COP? Or is it that the…

Air source heat pump vs oil - high install cost and higher running costs ?
I are trying to help the planet by reducing carbon emissions and have been led to believe that a heat pump should be approx equivalent in running costs to a boiler. I currently have an oil boiler and use about 2000 litres oil a year to heat bungalow (about 190m2). I’ve had quote for ASHP to replace upgrade most of the…
