Hello all.
I posted a problem on 15th March 2006 under ‘CH problem’ regarding hot water but no CH with a Potterton Flamingo 40 boiler, hot water cylinder, two open tanks in attic.
After advice from here, concluded it was a problem with port valve part of system.
After removing the actuator (Sunvic Duoval DM5651) I was able to manually turn the valve by hand (ie easily) to release water to the boiler to heat the radiators. Once the hot water runs out I turn the valve back for an hour or so to heat more water in the cylinder then turn back again so it reverts to heating water for the central heating when required. This seems to work ok as a temporary solution.
I’m about to replace the actuator ‘like for like’ as I did some research and discovered that it may be a problem with the ‘orange’ wire (that switches on the boiler when demand is for HW only I’m led to believe) but before I do replace could the problem be the valve itself ?? is there a way to test it? Should it be easily turnable by hand? Should it spring back or not??
Thanks in advance.
