central heating system running satisfactorily for one year.

[robert92elgin]

potterton 24HE installed over i year ago. Bungalow.

It has stopped providing heat to radiators. Green light for heat on. No burner caption. Turning tap 'on' causes burner caption to come on.

Slight weep noticed below boiler ( left of midposition) Very small amount.
Bleeding radiators ? No air what so ever.
Pressure gauge satis 1.6
Engineer says 'diverter', contact Potterton, its under guarantee.

Two men arrive say boilers working properly. They get boss to check, boiler ok, problems in the pipes under the floor? If this is so why is the pressure gauge not dropping?

Boiler set up to provided heat (Elgin, Scotland) but not water.

Boss said he would contact pottertons. No word from Pottertons.

If the boiler is firing for central heating then you have
a circulation problem.

If your boiler is not firing at all for central heating
then there is a boiler problem.

Thank you for your prompt reply.
The boiler has been set up by an engineer to supply hot water to radiators, with instructions not to attempt selecting hot water. ( This engineer was sent by Pottertons, as boiler under guarantee.) As a non expert I presume that the connections to the diverter valve have been switched. He stated that there is a problem under the floor?

Engineer states that there is a leak on the water supply side from the water main.
Boiler think hot water is being called for so heating side does not start.
Snag still exist(water leak) however boiler is working, no idea what he did.

DCawkwell.Thank once again for advice.
