This was asked of a mate of mine in his assessment today,and I'm not sure what the answer is:
Conventional cylinder with system boiler. CH turned off, HW on. Radiators downstairs are cold, but upstairs are warm. What is the most likely reason for this? Three of the options were
Cylinder stat faulty
Boiler stat faulty
Pumping over
He can't remember the fourth, which is a pity since can't see how any of the above could be the fault. Enlighten me
