CH won't fire up but pilot light is on....

[beadysam]

Hiya
I hope someone would be kind enough to help out...?

My hubby removed the livingroom radiator for decorating, then replaced it today. However, now we have a problem. We restarted the flow to the header tank, bled all the rads in the house, and turned on the CH. The pilot light is lit but the CH will not fire up. Therefore we have no hot water or heat. Its feezing here in North Wales and I haven't showered in 48hrs! YUCK!

Can anyone suggest ANYTHING that we can try...?

Thank you for your time

did you turn down your room stat on the wall???

 

[Blasphemous]

When you say you 'restarted the flow to the header tank', what exactely did you do to stop the flow to the header tank? i.e. before you removed the Rad and after you replaced it?

We tied off the ballcock, then released it when we had finished. The room stat is fine. CH/HW will not work - its not one its both!

Why the hell did you tie up the f&E to take a rad off???

 

[sime10]

have you turned any switches off?

 

[beadysam]

No idea why hubby tied it off - to stop it filling the system while he tried to empty it I suppose? No switches have been changed at all. The CH/HW was turned to frost but thats it....

Make sure any motorised vales were open while refilling.
Bleed thepump. Boiler may have lit and overheated due to having no water so look for overheat button.
Sorry not psychic - what's the boiler?

 

[beadysam]

We've bled the pump - there is water in the pump, rather than air.

No overheat button to be found.

The boiler has fired a couple of times but only for about 1min at a time. This is triggered only by turning boiler thermostst up to full.

The type of boiler: not sure of make/model etc but its NOT a combi, NOT a condensing, so I suppose its just a standard boiler! Sorry, can you tell I don't know wheat I'm talking about? Hubby isn't much better either.

Thanks for your suggestions - please keep them coming.

Cheers

look at the room stat on the wall, check that it is at 20. if switched to low setting this can happen what you are describing.Also I know this is a daft suggestion but do check your programmer.
I also agree about the reset button but without anymore info its hard to tell. is the pilot lit? If so and it only lights up for a few seconds then the problem could lie with the boiler, so get an engineer out.
