Central heating working upstairs, but not downstairs...

[dmlfc]

Hi. For the past couple of nights the heating in my house has been working fine upstairs (all the upstairs radiators heat up properly) but nothing is happening downstairs (none of those radiators heat up at all - stone cold!).

As far as I know the heating is all controlled by the thermostat which is in the downstairs living room.

Any idea of what may be the problem?

Pump stuck or knackered and gravity circulation is heating upstairs rads.

I assume thats the only pump is the one in the boilerhouse? Its located outside and level with the ground floor. Seems strange if its gone it can heat upstairs only, not the other way around:S

try turning all the valves off on the rad's upstairs to see ifyou get any heat downstairs, probably as gas4you say's the pump is on its last legs and because heat rises thats why your rad's upsatirs get hot even though the pump is in your outhouse
