I have a Morso Squirrel fire with a back boiler and air bleed screw,
supplying a single radiator in the stern bedroom, where there is an expansion tank.
The last time I used the fire, the expansion tank leaked and I replaced the
seal, since then, when the thermostat kicks in, the pump sounds like its working,
but neither pipe on the radiator gets hot.
When I've bled the radiater, water comes out, but no obvious air.
The expansion tank has been topped up.
Now it's getting a lot cooler at night, can anyone suggest anything I can do to get the radiator hot again ?
Cheers
