usually with a loss of hot water on a boiler and the heating still works ok means the heat exchanger is blocked and needs replacing or cleaning. it could also be a faulty sensor.

SOURCE: No heating and no hot water, my boiler won't fire up

If there is a hi-limit switch, maybe it's open, reset the switch, and monitor the temperature, if the temp. increases over the set temp. replace stat, and clean lime off from the tank, if does not have a filtering system

Vokera aav leaking


Robert, i'm sorry to say but the AAV's are machined parts and the seal should not have been broken by removing the cap. The floats are set perfectly and you would have been easier replacing the whole vent. You could have isolated all the pipes under the boiler and just drained the boiler down by releasing any pressure by the pressure release valve. You may need to buy another AAV and start again.

Low pressure on recently serviced Vokera 14/48se.


Identify the cold feed to the boiler, then look for a tap/service valve which when turned lets water into the boiler via a fill loop to pressurise it. 1-1.5 bar is ok
