Hi everyone,
I have a problem with my CH System -- I should add that I have very limited experience with CH systems but would like to have some idea of the problem before I call someone out.
My system consists of a boiler that heats both the CH and HW, a three-port valve, Grundfis Selectric (50hz) pump, room thermostat, HW cylinder, HW thermostat and Honeywell ST1000 timer.....
Last night, at around 8pm the CH reached the desired temp after a couple of hours, then the temp fell and, despite the room thermostat calling for heat, nothing else happened: the boiler didn't fire up and the pilot light wasn't on, but the timer was on. The pump was making a very low sound and I thought maybe the problem had something to do with the pump.
However, this morning the CH & HW has not come on at all, and l've noticed that the timer has not progressed to the on time: the clock is not ticking, so to speak. Advancing the timer does do something: the pump makes a low noise, the thermostat calls for heat and the pump makes the same low sound (the pump has a three-speed dial that sometimes if I increased it would seem to get the CH system going when it sounded like it was struggling) but the boiler does not fire up.
Is this two seperate problems? Boiler and timer? I moved into the house six-months ago and the system hasn't been serviced yet, which I think it probably needed to be flushed as the house is about 10 years old.
Any help would be greatly appreciated.
