We recently had a new boiler and controls (both Vaillant) installed, we also got TRVs on all of the radiators except the one in the room where the controls are - we were told this is because it could interfere with the thermostat. We were also told that one of the radiators must be left without a TRV, something to do with it protecting the boiler (because of the pressure or something) but I can't remember exactly why.
Anyway, we are having a problem because the room in which the thermostat is placed gets warm more quickly than some of the other rooms in the house and stays warm. This is because it is well insulated (we have external wall insulation at the back of the house and recently had new windows at the back too), and because there is no TRV on that radiator it is always hot when the heating is on. So when that room gets warm, the heating goes off, but the other rooms in the house are too cold, especially at the front where it is not insulated and we haven't yet replaced the windows.
The only way I can get a comfortable temperature throughout the house is to turn off the radiator in the room where the thermostat is, so this room doesn't get as hot and the heating stays on for longer. There isn't really anywhere else I can put the controls, so they need to stay in that room.
My question is, it is okay to turn this radiator off without damaging the boiler? If so, do I need to keep a different radiator turned on fully? The others all have a TRV but I am assuming if I set it to the maximum position, that radiator will always be on.
Thanks!
