I have a house built in 1994, so not quite to the same standard as today, and I’m gradually replacing things to improve it – mostly to do with heating and insulation. Looking at the rads now… there are two in the living room, about the same size – but one has a TRV, the other doesn't. I don’t mean it’s broken off or something – it has the smaller thingy at each end (sorry, I’m not a plumber) that just lets you turn it full on or full off, I think. Anyway, when the heating’s on, that rad is on full all the time.
Yet the 2nd reception room, about the same size, has two rads, both with TRVs. What’s the logic?
PS there is no room stat in this house (yet) – the only way of changing the overall heat level is by the stat on the actual boiler…
