Thermostatic valves for radiators - simple fit?

NIMAN

Was wondering if adding thermostatic valves to the rads in my house is a simple retrofit, or might I need to change the rads themselves?

You shouldn't need to change the rads, but having them flushed clean, as well as the rest of the system is never a bad idea.
Changing the valves will involve draining the system to some degree and often involves some slight pipework re - alignment depending on which type of valve is currently on the radiator.

I wouldn't bother with them. I've them in my house and i can't say there great,
Imo they are too close to the heat source,


I regret not putting in a wall thermostat in each zone, away from any rad, so when that reaches the desired setting the zone switches off

I think u can get wireless ones of these?

I replaced all rad valves in my house with TRVs in 2013, and went with Danfoss C2 in the end. Very good quality, with some nice features to make they easy to fit (i.e. they come with "bolt" cast into them, which is very good to get a grip on when tightening against it)

I find them very useful in regulating room temperature and have them coupled with a programmable thermostat doing the entire house

Wasn't too difficult to do, although quite daunting opening up the first pipe to drain down the system...

Same here. I've got them and don't think they're great at all.

They work very well if set up properly and left alone after that.
They give great control and good savings. There are a few good posts here on this forum on how to set them up.

There are better options, but TRVs are not to be dismissed by any means.
