Hi, my heating is not working but hot water works. i've got a Honeywell Sundial y Plan 3 way diverter (28mm) and what ive figured out is that the motorised valve (3 way diverter) is not working.
There is a handle on the side of it and if i manually push it towards one end, it spins the motor inside which activates the pump and opens up the VALVE “A”, for hot water to go to the radiators, it pumps out hot water for literally 2 seconds from the "A" Valve and the pipe which is going towards the radiator gets really hot, otherwise it remains luke warm.
Should I change the Honeywell sundial Y plan 3 way diverter to fix the problem???
Any suggestion????
