I would be curious how little energy it takes in summer as its still doing hot water. Pretty sure with the summer we had it could have acted like a heat exchanger alone and the water would have been warm enough. Its internal thermometer read well over 40c most days when it was in the sun.
Always worth pointing out that the kW of heat energy is only using between 0.25 and 0.5 kW of electricity to bring that heat into the house.
Heat pumps don’t generate heat; they literally move heat from the outside air, into the house…
Which is so much more efficient, it’s mind boggling there’s such resistance to it
