Hi
I have a good old Worcester 350 combi.
Hot water working fine, system has been drained, cleaned with Sentinel X400 and inhibitor X100 put into system.
Recently had new Thermistor fitted and flow switch kit (diverter valve?).
Problem is:- Central heating will not work at all, but hot water works fine. I do not think it is diverter because that is brand new.
Can anyone please advise why CH is not working?
Any advice would be appreciated.
Thanks
