Central heating problems

dabbler2004

First off bear with me as I try and explain this..
I can't use my timer anymore to have the heating come on automatically but the problem lies in the pump? that is attached to the waterpipe. This has to be set from auto to manual to have the heating work. There is a second pump? and that works fine on auto (one for upstairs and one down).
So do I need a plumber to fix this or an electrican and are these pumps repairable or does it need replacing? are these stanard?

Thanks

Are you maybe talking about a motorised valve, controlled by a thermostat or a timer, not a pump ?

i'm not exactly sure James so I took the following pictures;







It's the bottom one from the first picture

These look like motorised valves and from what you have described, it seems one is knackered. When these get power and is set to Auto, the lever should move across to manual or close enough. This obviously isn't happening. Strictly speking, it a job to be shared by a plumber and electrician but if you knew a good handyman, I think they should be your first call.

JamesM is right - they are motorised valves - they close when the temperature to which the stat is set has been acheived. There is one valve for each circuit. Check the thermostat for the problematic circuit and make sure it is not below the 'click'.

I can only see the bottom photo. It looks like there is some corrosion to the motor and the base and the wiring inside has probably shorted out. If you take off the motor and find that the base is not corroded and leaking, then an electrician (or handiman) could replace the motor - and also check out the thermostat and circuit. Any plumber who works on heating systems could also do the whole job.
