My boiler is the Glow Worm - Space saver MK11 and is currently on water only, as we don't need the radiators (it's 30 degree heat out there!) but my radiators are constantly comin on and we're all dying! how can we stop this, and how much (approx) will it cost me???

could be a motorized valve, either a two port or a three port letting by. prob lookin about £160 to repair.

Nothing if you turn the radiators off!
