Hot water but no heat to radiators?

[Wombat84]

We have a Worcester Bosch 280RSF and today our radiators died. We still have plenty hot water and the shower is working fine but the radiators are stone cold.

We have tried bleeding them and increasing the pressure in the system and resetting the thermostatic valves on every radiator but to no avail.

Any ideas what the problem could be?

Many thanks

It will be the syncron motor in the divertor valve........quite a nasty job to get to it.

Is it fixable or will we have to get a bloke out do you think?

Any more help people?

depends on what valve(s) you have, if its a honeywell easy, if its a myson/potterton, drayton etc you have to change the whole actuator (head)

the motor is about 15 plus VAT and shouldnt take more than an hour to change.

Both. The last one I did was a pain because you can't open the plastic casing on the motorised valve (ACL Drayton) without removing components. In theory that's not too difficult, but of course the pins and O rings are jammed, etc. I would say not a DIY job unless you like a real challenge.

Grrr! Sorry but I am getting so annoyed at out boiler! We only had the fan changed in it last summer so annoyed that it's broken down on us again. More frustratng this time cos we still have hot water - at least last time it was rally dead and we had nothing!

Just turn off the boiler completely and it will be less frustrating for you!
