I have just replaced a TRV with a new one because the old one was not working. It would allow the room and radiator to heat up, but then it would go cold and not come back on until I turned the thermostat up a bit more. The radiator would warm up but then it would go cold again and not come back on. The problem is that the new one is doing the same thing! The valve is mounted vertically and is quite near (2" away from) a surface mounted double socket. Could this have an effect on it's operation?
