immersion heater

painterman1 brought next idea :

Ours was put in as a standby twenty odd years ago and was never needed. I eventually diverted the circuit for other purposes, but made sure I could restore it in minutes should it ever be needed for its original purpose.

If yours is just a matter of reconnecting and you know what you are doing, just get on with it - there should not be a problem.

you wont know if theres a problem till you try it.

It's very likely the element has corroded through. You can but try, though.

And the thermostat might not have a safety cutout as all present day ones have . Stuart

True, but 2 deaths in 20 years is a safety record orders of magnitude better than most things we do daily.

Worth buying a new thermostat, if the heater element works. I believe that the mineral insulation inside the element sheath can absorb moisture, causing a leak to earth and making any RCDs trip. Once thgey heat up, the absorbed moisture evaporates.

Absolutely ........ I was just making the point tho' . :-)

What is the operation of the safety element? Overcurrent, overtemp. ?.

I fitted a new one to my daughters cistern and it has tripped twice since. The element looked perfect; no scale or distortion. I was unable to check for electrical faults.

Is there any possibility of a faulty cut-out?
