This boiler isn't new; the instructions stuck on the boiler's inside cover are dated 11/77 (tho they could still be using those instructions today ).
The problem is that the solenoid controlling the gas valve isn't always able to open the valve. On the occasions when this happens, the solenoid buzzes for a second or so as it tries to open the valve. Then it has a break for a while until it tries again. (Does the solenoid have a temp cutout to stop it from frying itself?)
The valve opens and the boiler fires first time more frequently than it doesn't.
Does anyone know if this - or an equivalent valve - is still available? The valve is stamped 7743. And then, what is it likely to cost to buy and have installed? Is this the time to be thinking of going fully pumped with a high efficiency boiler?
