I recently got caught out as the thermostat needed to be turned
anticlockwise to increase the temperature - I had turned it clockwise
and couldn't see why the water as colder and then I got a torch and
put my nose on the floor:-)

We tried turning it the other way and it definitely got even colder. I also
stuck a DVM in it to measure the resistance as I turned it
