CH problem with Vaillant combi.

natco · 8 Jan 2006

Hi all

Boiler : Vaillant VCW GB 221 H

Boiler is fine with hot water, but when central heating is switched on it works ie. radiators get warm for about 5-10 minutes, and then goes off. The boiler will do the same if tried again after 20-30 minutes.

Has been working fine for the past 5 years.

Any advice would be greatly appreciated.

Thanks in advance.
