I have a highflow 400 boiler and my wife insists on keeping the water on constant and the heating timed but on constant when it is cold which is usually most of winter but keep the stats on the radiators down low (2).
Someone (non-expert) has suggested also installing a room stat in the hallway. (the wiring is already there so I believe the previous owner had a stat there once). Could anybody advise on combination of rad stats and room stat or one or the other.
Many thanks
