Hello, i have a job that had an immersion heater overheating, i didn't know how old it was so just replaced it as they don't seem to last these days. Within a week it had overheated, so i reset it. Now a month later it has gone again, and maybe once more.
It's a 14" immersion, incoloy/titanium this time, on a direct combination cylinder, so the only source of heat. There is not a shower pump or anything. Going by the amount of plastic immersion heater caps littering the loft, this happens pretty often.
Can anyone think of any other reasons this keeps on happening? The only other thing i can think to check is the state of the ballvalve, i guess if that's getting stuck or running slowly it might be emptying and overheating because of that?
Any help appreciated, thankyou.
