Need help please... My Warmflow oil fired combi boiler will not supply hot water to my domestic taps but the central heating works fine. This is a dual pump system. I have linked out the connections on the boiler stat which causes the hot water pump and system to work and able to get very hot water from the taps but the boiler just keeps running along with the hot water pump. I have replaced the boiler stat with new one and at first was okay but once the boiler gets hot the stat no longer switches on and then we get cold water from hot taps.
Any suggestions
