Hi I have an old system where I have 2 x 2 port actuator valves honeywell, pump and baxi boiler. My HW valve head packed in a year ago so I just switched it off and jammed it open and it seems to heat the hot water cylnder when the heating kicks in (fine by me). The CH valve packed in the other day (checked with meter valve was getting power but not supplying power to boiler and pump). So ordered replacement head from toolstation £30 plus a spare motor £10 (tower make same spec volts etc). Wired the new head in (correctly) last night and hey presto it worked, however came home from work tonight and heating off again -aaarrrgghh! The Valve head feels hot but pipes cold, no power to boiler and pump again is it dead?. I did read somewhere the actual valve its self could be jamming but taking the head off it moves back and forward freely about 45 degrees. Anyone got any ideas, I feel like if I wire the spare motor in I am going to fry it. I have one seriously cold unhappy Australian wife ready to board a plane.
