Hi, I've got a Potterton Flamingo 20-30 boiler and water cylinder (see photos) fed from 2 large tanks feed & expansion tank.
Getting cooler now, so decided to put on the heating for 1st time since April and the boiler keeps cutting out after approx 5 minutes and there's no heating. The hot water is coming from the immersion as the leccy meter flashes fast when I run a hot tap.
I've bled the radiators with the heating off, valve near cylinder was half open and has no effect when fully opened so don't think I can bleed anywhere else.
Thought the problem might be a stuck valve in the pump as not been used since April but I can't see a pump anywhere, even checked under floorboards beside cylinder and cupboard below the water tanks only to find a 30 foot drop :0
No pump under the boiler as integrated washing machine there or in the under sink unit or any units on way to the cylinder.
This makes me think it might be an old gravity system but I'm not sure if the two larger pipes are the ones needed to make a gravity system viable or not?
I noticed that the water tank on the left appears to be considerably more empty than the idenatical one to its right, going by the sound they made when I hit them - not sure if that's significant?
