Hi,
Boiler: Ideal Classic NF (gas)
Age (of boiler): approx 15-16 years. People have been to service and replace bits of it occasionaly. I think the central heating pump was changed a couple of years ago.
Pumped system with indirect hot water heating. Small two-bed house, nothing fancy like different zones. No unreasonable demands on heating system.
For a year or two now the boiler often clicks a lot, sometimes in rapid succession, after firing up. It normally stays lit during the clicking but sometimes would go out and then immediately relight. It didn't seem to affect its overall performance so nothing was done to it.
Recently, the heating and hot water stopped working, The boiler wouldn't fire up when it was supposed to and we had a few cold mornings and cold showers. The 3 port mid position valve was changed (even though it now seems that maybe that wasn't the problem). The guy who changed the valve said that he thought the timer-control was actually faulty as the heating wouldn't come on without the hot-water being on. I changed the timer-control for a new compatible one and now the hot water and heating do come on independently when required. However.......
The boiler is back to doing its clicking thing after firing up AND the boiler will not stay on for a long time, even though the temperature has not reached the room thermostat setting yet.
The radiators do usually get very hot (upstairs and downstairs).
The thermostat dial on the front of the boiler is set quite high (about 5.5 on a scale of 1-6).
Sometimes the radiators are not hot in the morning.
After the boiler has cut out...
a) it can be restarted by dialing the room thermostat down until it clicks off, waiting a second then turning it back up again. However it won't stay on for long though.
b) if left alone it will start up by itself again but won't stay on for long.
c) turning up the boiler thermostat control will allow the boiler to start again for a little while.
I've checked the room thermostat with a multimeter and it seems to be functioning correctly.
It's as though the boiler is getting too hot and is switching itself off until it's cooled a bit. The boiler itself isn't particularly noisy when it runs (doesn't seem to "kettle"). Sometimes after the boiler fires up or shuts down you can hear the sound of water in the pipes and radiators, it's not excessive but can be noticeable.
Any suggestions for anything I could check or what the problem might be?
Many thanks,
Ray
