TRVs Information please on how they work.

[Unklian]

Hi Folks.
Nothing urgent,
Just wondering......

Set my TRVs so the room is at about 21 degrees.
Boiler fires up heats radiator etc.

How does the TRV sense the room temperature accurately when there is a
pipe directly underneath it at about 80 degrees C ?

Surely the air around the TRV will be VERY hot, much warmer than the room? How does a couple of degrees difference in the room open the valve again if the pipework is still hot?

Cheers.

Ian.

TRV's don't work by being accurate, they work by finding a setting that works and sticking to it

If you require greater accuracy you can mount them horizontally.

Believe it or not but i bet the manufacturers who designed them had a slight inclination that they would be fitted next to big hot radiators and pipes and allowed for this
