A unit of electricity is the KWh (KiloWatt hour), which is the amount of energy used by a 1KW appliance in one hour.
So your immersion will use 2-3 units per hour. Depending on the cost of a 'unit' from your supplier, (typically around 10p per KWh inc. VAT), then you are looking at 20 - 30p per hour max.
Remember though, once your immersion reaches the temperature of the thermostat setting, it will switch off. So, if starting from cold, once it reaches the correct temperature
