have noticed for a while now that the hot water cylinder stat might not be working correctly. Hot water is timed for morning and evening only however as it only comes on for a few hours i just put it down to it not heating up fully, stat is on 55c.
Now this morning, i switched on the immersion heater which heated the water, all this while the boiler was still heating the HW. After all baths were done with, the immersion gets switched off at 7 as we have an economy 7 meter, the boiler was still going, central heating was not calling for heat. I started hearing tapping and bizzare sounds in the hw cylinder after an hour or so. The pipeline coming out the top was very hot. I turned down the hw stat and it didnt click off until it got to 40c. I left it off for a few minutes until boiler and pump were off, so this all works. Then turned the stat back up and it immediately clicked at 40c and pump started running. the water in the tank is def above 40c though not sure how i can check for sure.
So does this mean that the stat is faulty?
