    Today we seem to have a problem with our central heating - none of the rads are heating up. I've checked the boiler, and it's firing up. Also checked the circulation pump, and it appears to be working. The pipes are hot coming out of the cylinder. Could it be a valve problem? Any ideas what I can check?
    It's a conventional boiler, not combi.

    Could well be a 3-port valve in which the little motor/actuator needs replacing.
    There are threads monitored by heating experts in the General Chat section of these forums.

    As a 'get by' these 3 way valves usually have a manual control lever so that in the event of failure it can be placed into the mid position so that heating and hot water can still be had until it can be fixed.

    Thanks guys. I checked the actuator and it was working fine. But when I took it off the valve to expose the spindle I just couldn't shift it. Bit of WD40, and now working smoothly. Problem solved!
