Hello, can anybody please help?! My Keston C36 boiler is producing hot water fine but my radiators are stone cold. I've checked the wireless temperature control and re-introduced it but its still not working. It tries to fire up and then makes a burping noise and stops. When run the hot water tap it fires up just fine. There is no error code when I hold reset so I'm stuck. Any ideas would be greatfully recieved. Many Thanks. Ed
