I have a Potterton Netaheat central heating boiler which just runs the heating system.
The water tank in the loft that feeds the system is getting hot,
I now notice that hot water is running into the tank from what i beleve to be the vent pipe.
The system appears to be working ok apart from this problem,
I have checked the pump and that is working ok,
Any help on this would be appreciated.
