I guess what I’m really doing is trying to gather information to question what the developer has installed & has it been installed and configured correctly, and possibly the thermal efficiency of the building. I’m trying to eek information out of them on the sizing of the system & any heat loss they did - but having met the plumber that said he installed it I have my doubts any of that was done & it was fitted like a boiler. The 660kwh I mentioned, I don’t think that’s heat output I think that’s electricity used by the heat pump, as the screen seems to describe it as “usage”.

Hi all, new to the forum & wanted to fish for some information on the LG Therma V. We’ve just moved in to a new build with an 12kw Therma V, underfloor downstairs & radiators upstairs. We’ve been in 2 weeks now & I’ve been reading the information in this thread & set the weather compensation curve from a static 50 degrees flow temperature to using @ReedRichards target temperatures. One thing I wanted to ask folks in the know, it feels like it’s using a LOT of energy. If I’m reading the summary screen right, just over 660kwh in 2 weeks. Does that sound normal for a 4 bed new build, with a B rated EPC and estimated yearly heating requirement of around 9000kwh?
