Rated 3 out of 5 by from Head didn't fit my immersion heater My old thermostat functions but the (Bakelite?) casing is cracked so I wanted to replace it. The head on this is very slightly too big to fit. Like another reviewer I was reluctant to bend the terminal on the inversion heater out the way - I thought it might work with some slight shaving of the plastic but that still wasn't quite enough so if you have the same problem, you might want to return it rather than trying that!

Rated 4 out of 5 by from Cheap and available for quick click & collect. Only thing to note is that the head is marginally bigger than that on the failed unit it was replacing, so installation took a bit more effort as had to bend a connector on the heating element out of the way. No supplier's website gives that level of technical spec, so is something you can't check before purchase.
