All sorted
The heater that was taken off broke the circulation of water in the system - hence the problem. Heater is back on, boiler is functioning
thanks for your replies
Hi all,
my almost new (installed in october) baxi combi HE 33 refuses to fire up although I have topped up the pressure to 1.5 as per the user manual.
The pressure had dropped zero as the the lads installing a new bathroom removed a bathroom heater
Any ideas to get this going again...
