Hi everyone, Thought I would give an update here, and given the recent cold snap in the UK it would seem a good time to do so. We live in Woking, o...
@sunandair your logic makes sense. My concern is that my COP is 2.5 at best. So I’m trying to find the best set up to maximise the COP, and then un...
@sunandair Ah okay so you also get some cycling when the OAT low double digits. What is your COP? Interestingly I spoke to the installer briefly...
