Hi you Guys really seem to know your stuff. I have one of the old trombone heaters with no pressure switch. Watkins 0939401 Is it possible for this to be intermittent? The heater light is on and I have flushed the water through but sometimes it works and sometimes it does not. Is there a way of testing if it is on rather than coming back every 6 hours to see if its warm? Many thanks Graham
