Why does heating always pack up when the weather gets cold?
We have been in this house for 5 years and the heating system has worked perfectly.
Now for some reason the boiler won't fire up to heat the radiators on their own but will only fire up when hot water requires heating. When this happens the radiators will heat up if the thermostat demands.
The pump appears to be working fine , the 3 port motorised valve appears to operate ok and I assumed that this meant the programmer was at fault. No such luck.
Just got a brand new programmer and fitted only to find I still have the same problem!!!!
Boiler is a Potterton oil-fired, programmer is Siemens/Landis, motorised valve is Landis, pump is Grundfos, tank stat is Landis and room stat is Landis.
I think the system is about 7 years old and as I say has worked perfectly up 'til now.
Can anyone help.
Would call a plumber but they are like hens teeth around here.
