Our boiler heats both the Central heating and the hot water. The hot water coming out of the bath and sink taps is nearly scaliding, even though the theromstat is thurned down to approx 45 - 50 deg. I understand that the standard setting is 60 deg ?
I suspect the thermostat may be faulty, but how can I check.
When the boiler is running and I turn the thermostat down or up, you can hear the valve opening and closing to heat either the water or the central heating.
Any assistance greatly appreciated.
