Fitting Thermostatic Rad Valves
I am intending to fit Thermostatic Rad valves to all my radiators. I have heard that it is important to leave one radiator without a TRV but do not really understand why this is necessary. Also my current system does not have TRV's and uses a single room thermostat mounted in the hall. When TRV's are fitted, the pump will run when the hall temperature is below the setting of the room thermostat but if the hall TRV is on a low setting the pump will run continuously, as the hall radiator will be off.
What is the correct way to resolve this?
