Hi to all
I have a problem with our heating system. The boiler is a Potterton 80f F/R 28mm with a Drayton 28mm three port valve.Pipes to hot tank are 22mm the same as the heating. The pump is a Grundfoss 15/60.the problem is the boiler keeps overheating and cutting out, when the heating is on its ok on hot water alone. I have flushed the system. but cannot get the thermostat on the boiler above 2.5. Is the pump big enough or do I have another problem? Thanks in advance
