You may be right but so far three engineers have charged me for them to guess whats wrong - I can guess myself for free :D If the problem is the old style 5102160 PCB (which mostly suffers from lockouts) and the latest version will fix it garantueed then I'm happy to pay someone to come out...

Sounds like you have the same problem as me - continous store demands for heat but the boiler anti-cycles because its own temperature is satisfied. If your asking about PCB version 5102160 I've changed mine (reconditioned) and it didn't help, neither did changing the thermistor or boiler...

The cycling happens when the store reaches about 73C and as BigBurner says the store is self adaptive to the boiler output when setting the store temp range, this it sets at 74C to 77C. This matches my neighbours setting who have the exact (albeit working) system. As an experiment I removed...

Wow, quick response! Thanks guys. The store was drained to replace the valves above and below the pumps as these were leaking when the system got cold (as I don't leave it on while it has this problem) and the water was clear. Even though the pumps sounded fine the boiler/CH pumps were...

Hi all I'm looking for some advice (aren't we all!) with regards my heating issue. The problem is the store (Boliermate 2000) never gets upto temp because the boiler (Potterton Suprima 40l) goes into anti cycle mode believing the boiler temp control is satisfied. However the store is not...
