HWCH : Thermostat for one room

[Frank Z]

I am fitting a new radiator in the living room. In the other rooms I have used TRVs to control the room temprature. In this room, however, a TRV would be ineffective because the TRV would be covered by a floor-length curtain, due to the position of the rad.. What other method can I employ to control the temerature of the room? I know you can buy in-line electric-powered valves which can be controlled by a standard room thermostat, but is there any other method - perhaps something that doesn't require an electric supply? How about an in-line TRV? Are there such things?

Thanks

Frank

You can get in-line rad valves, a quick look shows one in srewfix, code

35602, at all the major manufacturers make TRVs with remote sensors which let you site the sensor up to 2 or 5m away from from the rad. Try finding a plumbers' merchant with one in stock tho ;-), but you could order one and that seems like a good bet. Btw, they are non electric & work via a fine capillary tube connected to small remote sense capsule.

Bear in mind that when you close those lovely floor length curtains that you won't get much heat into the room from the rad. For my big rooms I have a small rad at the windows to cover the loss there plus other rads to heat the room proper. Smaller rooms just have a rad _near_ the window, to cover the window loss & heat the room.

Fred - thank you for your help. Yes, I have puzzled over the rad positioning question for this room. Under the window seems the only place whare I can afford to take up wall space with a rad. So I have put venetian blinds on the wiindow. The floor-length curtains are for looks only (to prevent the room looking too stark), and will not be drawn closed - not during winter, anyway. Only the ends of the rad will be covered by the curtains. It's not an ideal situation - but life is often like that - a compromise. Warm air heating would have been best for this room, in an ideal world. Thank you for the info on remote TRVs.

That sounds like a good compromise. I had a long session of soul searching before positioning mine, even now I wonder if I got it right. Remote sense head sounds good for you, sorry I couldn't find a supplier.
