Re: Fitting Thermostatic Rad Valves
you don't fit trvs in the same room as a room stat, they play against each other.
when one rad is left without a trv that rad is used as a bypass. in your case the hall rad.
most boilers have a bypass fitted to them now days. and if yours is an old system boiler does it have a pump over run ?
and is it a y plan or s plan
