Great site! Maybe I can pick someone's brain for some advice...
I think there may be something wrong with my CH pump. I have a Baxi gas boiler in my bathroom controlled by a timer in my kitchen. When I set the timer to heat the water and/or the CH there is no problem, the water in the tank/radiators gets hot as required.
However, when I switch off the CH and hot water heating, there is still the slight gurgling of circulating water in the system and a distinct faitn whirring, as if the pump is continuously *on*. I noticed this around 8 weeks ago and now have some free time to investigate further. At the moment I am turning the boiler thermostat wheel to 'off' when it is not required for the hot water etc.
Even though the boiler is 'off', the water passing through the pipe either side of the pump is somehow still hot.
So I am wondering whether I simply need to replace the pump... or the electronic timer... or the boiler? The pump was only replaced about three years ago. The boiler is at least 20 years old but has given no problems.
