Immersion Hi Limit Stat

[Johntheo5]

The Hi Limit Stat on this is open circuit and apparently is non resettable?, I'm told its screwed into the immersion element, can it be removed without draining down. Apoligies for bad photo.

If you’re on about the blue plastic part, then yes it should be ok as it doesn’t make contact with the water

I think it will just pull out when disconnected

You can get the 7" thermostat with or without a reset

one shown has a reset, if the immersion heater is the only way to heat the DHW then better without the reset, however if there is an alternative method to heat the water, then better with a reset, as the other method could cause it to trip.

No, the blue (Backer) is the control stat, I'm talking about the HI limit stat (with white wires) which apparently is screwed down into the immersion element.

Ah, in which case I’d say no, must be new immersion, or maybe dual function thermostat?

You could always contact Backer/Heatrod? https://www.backer.co.uk/pages/faq

They can be bought, however this one

has it built into the thermostat, so just swap to a thermostat with the cut out built in.
