I am still a bit confused ... just moved to a "new" house.
Rads have TRV's ..... There is a wall thermostat in the hall at bottom of the stairs ... and NO radiator.
So ......... if I set the hall thermostat to 20deg and wish the other rooms to be the same temperature (20 deg) with doors shut, I can control rooms with TRV's .... right ?
So what happens when the rooms reach 20deg? I assume the TRV's shut the water feed to the rads.
So what is happening in the hall and the upstairs landing space etc ? Hot air rises so will the boiler keep grinding away until it is 20deg at the bottom of the stairs in the hall to the top ?
I do not really want it that warm up there.
