A typical electric immersion heater for you hot water tank is 3kW (Kilowatt). With a typical daytime electric tarriff of 15p per kWh (kilowatt hour), it costs 45p per hour to heat your hot water with an immersion. Heating with gas will be significantly cheaper.Gas is currently 5p per kWh and assuming you have an old inefficient boiler running at 80% efficiency, it will be costing you 7p per kWh.ssuming you are paying 15p per kwh this equates to 15p per day or Â£54 per year. If the immersion is on just before you need the hot water rather than heating up hours before then the standing losses will be reduced. A simple way to save Â£54 is turn the immersion on 2 hour before you need the hot water.
