Dual Safety Thermostat 18"
The safety over temperature cut out keep tripping on our immersion heater.
I tried to get a replacement but with no joy and also I was told it was the adjustable thermostat may have failed causing the water to overheat.
I saw this one on the Screwfix website that included both at a great price and was in stock at my local store.......an hour later the immersion was up and running again!

No More Scalding
Have fitted several of these over the years, Very simple two wire fitting, save a few bob on calling a tradesman, sorry!
If used in conjunction with a decent Immersion heater timer switch you should get plenty of hot water in around 20 mins of running cost.
Easy to replace and fit, just isolate the electric to the area first.
I have replaced similar products on average every 18 months, contactors inside do seem to weld themselves over time. So can't comment on reliability of this unit.
Worth the money, could easily save it's cost over a year with temperature tweaking and as I said before a good timer switch specific to the job.

Very easy to replace, just undo the two wires, after ensuring power is off, and slide out. Slide new one in and reconnect wires. 18in thermostat fits 27in heater.

Bought this dual safety thermostate to replace existing burnt out one. These are very easy to install you need to turn off power supply to switch remove emmerstion heater top cover disconnect the two wires connected to thermostate and remove. Once out you need to measure the length so you purchase the right length.Fitting is the reverse of removal.Very pleased with purchase price and would recommend to anyone.
