Thinking about the hot summer which is now upon us, and my heating for next window.  I have GFCH and a big (10 kWp) solar array, facing E/W.   I can't do anything physical to the house currently as half of it still stuck in a family estate.   So I'm looking at this kind of thing - a portable a/c, which comes optionally with a heat pump, which I have not seen before. Or a slightly smaller version of the same.   https://www.appliancesdirect.co.uk/p/airflex15/electriq-
