Also found this list of heat pump problems that can help better understand - https://jlphillips.co.uk/heat-pump-problems/

I agree with what is mentioned, people should avoid changing the temperature and let the thermostat do its things. I've noticed a significant shift in the usage of heat pumps, particularly over gas boilers and it's truly a good one.

Does anyone remember homes heated with ducted warm powered by gas or electric off peak storage. This type of heating system powered by an air source heat pump makes very good sense for a modern well insulated home and is the type of heating which is the norm in the US and Canada.


We’ve recently completed a passive house build of 230m2 powered by a small air to air heat pump of only 5kw maximum output which when combined with 6kw of solar panels provides all the heating and hot water needed for a very comfortable home with about 3000kwh of energy imported from the grid per year.


In our experience air source heatpumps heating water for heat distribution seems unnecessarly complex, expensive and inefficient for modern homes.

You will NOT be kept warm enough, believe me. I have a relative with a very old house on the Pennines. She installed a GSHP (which needs a lot of electricity to keep it going) new radiators etc - not underfloor heating though. She wanted to be eco friendly with an eye to the future. Her house is cold. Absolutely cold. In an effort to reduce her electric bill (gas not available) she has now installed many solar panels in her field, removed the electric AGA, which kept the large kitchen diner cosy. We now can only sit in there in the summer. It’s cold. At what cost all this expensive work was done - I don’t know. She would never say. It must be huge judging by the permitted work that has been done (Grade II listed house). In order to maintain a lower energy bill, she switches everything off. Not worth it IMHO. My advice would be: insulate your house as much as you can & buy the best, most efficient gas boiler and air to see what happens in the future. It’s all we can realistically do.
