Biasi Riva Advance HE - scalding DHW and luke warm CH?
Anonymous user 28/02/2024 - 3.07 PM
Experts, help here would be greatly appreciated. Boiler is 18mths old (Biasi Riva Advance HE), central heating never been brilliant but I put that down to radiators been sludged up as never been off wall for 20 years. At the weekend finally took plunge, removed and jetwashed/flushed every radiator. Now all back together very little difference :-( DHW scalding hot but after connecting a hose pipe to my CH flow pipe I find the water coming out is only hand hot when the boiler is in operation. Diverter seems OK (spindle seems to activate microswitch with force) but not sure what to test next ? Thoughts would be really appreciated . Thanks
