I agree .I think it's a boiler issue myself as have tried everything.
Have booked rhe boiler company for the 16th so one more week of cold .hope fixed after that .
Thankyou for advice
Thankyou for this .I'm not sure what the plumber did .he did something to the co.unial timer and said hopefully the heating will work when the timer kicks in layer but it didnt work.
Back fill may be the answerr I'll Google how to do that and have a go in the morning and let u know if it works...
The other flats are ok .
This has been going on a couple weeks .
Had 3 plumbers round .one did get it going but then it stopped and can't get hold of the guy now .
As we all know pretty cold atm.have a electric rad but as the system is for the block I'm paying double bills .getting to expensive...
Thankyou
No boiler I the flat .a communal boiler in the basement. Cylinder tank in the flat and water tank above it .
No expansion tank and the diverters are ok .
So the boiler serves 4 flats mine at the top .
Thankyou
