Mend Bosch Boiler Water Properly

Wocester Bosch 35cdi II boiler not heating water properly?

Hi,

All of a sudden my combi boiler is not heating the water properly. The pressure seems good. If I fully open the tap the boiler goes on then the water heats up for a while but then gets cold again .Any ideas?
Thanks

i think its your diverter valve hundred pound for the part.i had to have one and a pressure vessel hundred pound as well,so i had a new worcester greenstar condensing boiler 30cdi.fitted i think this was the best option.otherwise you could keep spending more money.
