@sapper117 sounds good. Cheaper, warmer and most importantly a happy partner. Our wood and coal burners are now also nice to haves rather than th...
@cathoderay Do the Midea capacity figures include an allowance for defrosts? Mitsubishi's data includes this for its 2 deg C figures. In that link...

@robl thanks, I think I totally misunderstood what a heat exchanger/PHE was. I think I do now. We don't have one and it seems to be fine without ...
I'm not sure I understand; are you saying if you have a PHE then water out is 5 deg less (or even 22 deg less) than water in? Where does all that ene...
