Hi, I have a standard open-vented system with an old back boiler behind a fireplace downstairs feeding 7 radiators.
I'm about to fit TRV's on all the radiators and also replace the lock shield valves. (I'll probably take the radiators in the garden 1 by 1 and rinse through with a hose as they are quite old but in good nick!)
Should the TRV's be installed on the 'flow in' or 'flow out' of the radiator? or does it matter?
I'm not going to fit on on the hallway radiator as there is a room thermostat in there.
Any tips - or is this the correct way to do this? Oh, I normally leave my boiler on setting 3 of 5 but I've heard it's more efficient to leave it on Max - is this correct?
Thanks in advance.
