I'm planning to install a new switch for the immersion heater. Currently there is a socket in the airing cupboard, which the immersion plugs into.
This socket is on a dedicated circuit and the consumer unit has a circuit breaker marked "water heater". It does not indicate any amps other than "B 16" whatever that means....
I've been told to use a double pole 20A switch - what does the 'double pole' mean?
Also suggested was a cooker switch (32A) though not sure why!?
Screwfix have two switches which seem to be similar except one has 'water heater' written on it! Will they both do the job?

Anything else I should consider?
cheers.
