Anyone can help? Thanks a lot!
Dear SunBeam,
Thanks for your help in advance. I can not post any here, so i have to send message to you here. Hope you can help!
I have a Puma 80 Combi boiler at home and the centrol heating is not working properly. I have read the forum below:
As you said, it maybe divert problem. I have changed the pump and divert already. But it still no CH. I always set the CH as continus. However it turn off after 30s or few mins.
1. I was thinking it is gas in the air. After i bled the air, still no luck.
2. then i think it is pump, i changed pump. Still no luck. But i can feel the CH hot water pipe is warm. the PUmp is really hot.
3. then I changed the divert. The problem still happens (clicking on and off every few secs as it went.) However, i can feel some radiators are working and CH hot water pipe are hot.
4. Then I clean the raidiator. This time the heater rung for a long time, but suddently off and clicking on and off every few secs as it went. Only 1/3 of the bigest radiator seems warm. Then it cool down after heater not running properly.
5. in these two days, i tried to touch the CH cold pipe it seems it much hoter than the CH hot pipe. I think it is unusual.
Really do not know what happen now. Also there is a valve which connect from CH hot pipe to CH cold pipe? Should i close or open it? What is this used for?
Could you help me ASAp? As this happens and we can not get any CH at home. Thanks a lot!
