    TSE / TSR difference in immersion thermostats

    Hi, I understand that the TSR temperature sensor is in the thermostat stem and not in the head, like with the TSE version - but what is the benefit of TSR over TSE? Many thanks, Richx_uk

    I need such a spanner to remove a failed IH, and to install a replacement; in a domestic hot water cylinder made by Opus (Cyprus). I am aware that in general the distance across the flats may vary somewhat from brand to brand, despite all having 1.5" BSP threads. In my case, both old and new IH...

    Woke up at 6AM to the sound of my hot water tank boiling and a cold sweat as I realised I'd left the immersion on since 6PM the night before.
