Hi all Puzzling one which my local heating engineer can't solve, who gave the boiler a clean bill of health but doesn't know much about Hive. I'm obviously not an engineer but I'm convinced the Hive wiring is at fault here somehow. The system was installed before we moved in. I found a similar...

Hi, I have a Potterton Statesman oil boiler using its integrated stat for temp control. The boiler fires up as normal as far as the stat is set below half way (unfortunately not hot enough to heat up the house in cold weather). If the stat is set above half way, the overheat light (red one)...

I have had plumber in re do my bathroom to put in mains shower rather than electric while away. I got back and pressure was zero which was because hr had drained system. He was called away last minute so was part way through job. He came to finish off yesterday and it turns out he hadnt drained...
