That's good to know - and in which case, adding anything fancy to the system to "automate" it sounds like (a) an unnecessary complication; and (b) lik...
Is that really the case? Won’t the rate of heat loss in the room change as it cools/warms outside and thus what it is balanced for today at 1c isn’t ...
Almost but not quite a trv with remote sensor. A trv with or without a remote sensor operates principally, so far as I know, as an on off device (alb...

Many people with heat pumps heat water only to say 48 with a weekly legionella cycle (often using the immersion) taking it to 60/65. This should all ...
Good spot on the data. The physical size of the 7,kW model is different however so I don't think it's likely the 5 is entirely a SW mod of the 7, how...
Fair enough, I was just checking I hadn't missed something! Thanks for replying.
