Measuring power consumption of immersion heater?
I recently bought Aldi's power meter,
which I have found quite instructive -
I was surprised that my Sky box and TV
took 20 watts each in standby.
This led me to wonder how I could measure
the power consumption of our 2 immersion heaters.
I assume it is dangerous, probably illegal,
to fit a power socket in the bathroom.
Is there any simple way of getting round this?
