combi boiler - water working - heating not

verysagey

Can anyone help before I call out an expensive plumber.

Got up this morning - house was cold - have done the pressure thingy on the boiler to make sure that was ok - and have perfectly ok water. Have switched system off left for a while and switched back on again - boiler fired up then went off. Thought it could be the room thermostat - but could it be other things too - the boiler is working fine - it is just the central heating that is not coming on - anyone got any ideas please???

Sounds like the pump to me.

No it's not. Most likely cause is the timer or thermostat as you originally thought.

Hi

Make and model would help.
First thing is to check that all the external controls ,room stat and or programmer are actually calling for heat.You might have a programmer built in to the boiler.
Next would be the divertor.
If you have to ask how to test the electrics on the controls then I guess you need an expensive electrician.;) Followed by the expensive plumber or corgi for the divertor.:rolleyes:

Testing? I was always taught to change every conceivable part until normal operation resumed. Rogue Traders taught me that one.

Trying to think of excuses why all of the new bits didn't work - now thats a skill.

We had a similar problem, it turned out to be the 3 way valve

thank you for all of your replies - just trying to see if i have a friend that will help me test everything - sounds like it basically could be lots of things but thanks to you all for your suggestions.

its a vokera maxin 24 or 28e - not sure which. All the controls are as should be - it was on last night until timer went off but it didnt come on this morning, have tried switching things on and off but basically everything was the same, it just didnt come on
