Hi this is all new to me, so...
My heating hasn't worked properly for years, every year I get the boiler serviced and am told that it's burning efficiently, so have put the problem down to muck in the radiators which is keeping the downstairs rads cool/cold... hot water has never been a problem.
Recently, with winter closing in, I replaced the motorised valve above the pump and after a couple of loud bangs and cracks in the pipes, suddently I had ehating and hot water!! Great I thought, but yesterday, after about a week and a half, nothing
I noticed that the pilot light had gone out and became a real pain to relight (it ketp/keeps going out). I guess the obvious solution here is to replace the thermocouple, which I will today, but...
The pilot light did eventually stay on all evening, but the main burner on the boiler wasn't kicking in and out as it should have done - considering all of the raditators were cold!
On the odd occassion when the main burner did kick in, after about 10 seconds or so, it made a few loud cracks and bangs (coming from the boiler) and then went out again..thus not hot water getting up to the pump.
I'm thinking maybe the pump has had it, which is causing an insufficient flow of water through the boiler...could this be right?
If so, I guess the noise I hear is the water boiling and eventually causing a safety cutoff or something??
I have noticed that there are a few 'tinkling' nosies to be heard from the pump when you change speeds on it, almost as if there is some debrit going through it.
Any ideas?
Should I replace the pump? Or Hi & Lo thermostats? Or the pump overrun thermostat?
Any help would be appreciated.
Thanks
Dave
