We have a Main 30he combi,
Approx 3 months ago,the wall start wasn't controlling the boiler,so I changed the stat and still the same problem.
I noticed the bedroom rad was leaking(not the valve but the actual rad)terribly rusted which crumbled in my hands...I cut the supply to the rad but as yet havnt changed the rad.
The boiler comes on for 25 seconds then cuts out for approx 3 minutes then comes on for 25 seconds and so on....rads upstairs are warmish whilst downstairs all cold.
Drained down the system and refilled and removed air...checked the pump which turns easily.
The pump makes a hissing/gurgling type of noise whilst the pipes by the boiler sound like a bath tub being emptied
Any ideas would be greatly appreciated .
