Hi, I have a standard Honeywell thermo unit strapped to the side of the tank. It was playing up, good water temp for a few days, hot but you could wash hands under it, just.. to the 5th day where it would be hotter than a kettle, scalding temp.
I replaced the unit, took mins, now does the same thing. I have removed the stat, carefully sanded the copper to expose fresh copper (tank is 30 yrs) jiggled it and then popped it all back on. Seemed ok for a week, then back to being scalding. Everything else in the system works. Heating is as good as, etc.. just when the water is that hot a) it's scalding hot b) the aqualisa pump suffers from air in the system and or week impeller as the water flow goes down.
Fiddle with the dial, set it back to 40 and then it settles back to normal temp. I run the shower with no hose to clear the system, then back to normal .
Any ideas on this irregular issue?
Thanks
