Can anybody help ? I have a Potterton Combi 80 Combi Boiler (not Puma) and the hot water keeps going hot and cold. An engineer has visited the boiler and changed the Diverter Valve and the Air Flow Switch.
He has taken out the water input restricter as he said the problem seemed like the water pressure was to low. The problem is still their and the hot water is still only 1/2 as powerful as the cold water.
Can any body advise on what it could be ? Could it be the Heat exchange unit ?
