Air Sourced Heat Pump.

Zoomup
A person today that I was talking to, that has had a new build home which was required by building regs. to have an air sourced heat pump for heating and hot water, complained that the system was slow to heat or cool as required. He said that he had to have underfloor heating installed. It was slow to warm the rooms on cold days. He recently had the system set to cool the rooms on the very hot recent days. But this morning was cooler and he required heating. Is this normal?

    Do heat pumps provide hot water in the same way as a combi or do they need tanks? If it's the latter, then it's going to be a right pain for a lot of people to switch from gas as there's probably nowhere for a storage tank.


    They produce a much lower output than a typical combi boiler.  Enough for a shower, perhaps, but not much else.  In practice, they need a hot water tank, and even then they need an immersion heater for a heat boost to sterilise the water every week or so.
