Thermal fuse/cutouts

I have a night storage heater (bricks are inside). I want to replace thermal fuse. The specification cannt be read on it. It is ceramic type.

The answer to your query is at your finger tips :lol:
Just type the exact make and model in 'google' and you'll get 3 hits.
The first I looked at has a list of all the spare parts, you can buy them on the net.
