I have a problem on a Baxi Bermuda Back Boiler System as in that i get hot water when called for but don't get any heating. The boiler will fire up for about 15 seconds then cuts out back to pilot.
The hot water side is gravity fed with 28mm pipe. The heating side is a pumped system and fed in 22mm pipe.
Checked pump, working fine, also checked spindle inside pump and found to be working. On feeling the pipes from the pump water can be felt flowing. Their is no heat at the inlet or outlet side of the pump but as already stated water can be felt flowing through the pipework.
Checked roomstat and voltage feeding roomstat ok.
I am left with 2 possible problems:
Zone valve Knacked or an air lock in the system.
Looked every were for the zone valve but cant find one including the tank area. Anyone know where i might find it, will it be located someplace near the pump?. As i understand it some systems are not fitted with a zone valve?
Could it be anything else causing the problem?
Many thanks
