Thermostatic Radiator Valves.

[braindrain]

I am fitting TRV's to radiators in my house. Please could some one tell me if I have two radiators in a room do I need to fit TRV's to both rads and secondly should I fit one to the bathroom rad and to the hall radiator where the Room Stat is fixed?
Thanks

Yes fit TRV's to both rads, the bathroom rad if you like but they are often draped in towels which can shut the valve off (if the head is covered), the room stat rad should not have a TRV fitted.

Only fit Honeywell, Danfoss or Drayton ie quality brands. Most other TRV's less than say £8.00 are rubbish (reduced flow, leak, jam, heads break off etc).

Depending on yout system setup you may need an automatic bypass valve to keep sufficient flow through the boiler and prevent excessive noise through the valves.

no.

If you have a combi boiler DON'T fit a TRV on the bathroom rad just 2 lockshields..........

There is nothing special about a combi in the heating mode!
