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.
Cost of running an immersion heater. The cost of electricity is about 14p/kWh, which means that it would cost about 45p to run a 3kW immersion heater for an hour.Normally though the immersion will turn on and off via the thermostat so the amount of time they are on fluctuates, depending on the existing temperature of the water in the hot water tank.f you take the above example and have a 3kW immersion heater it would take about 2hrs 30 to heat the water (3kW each hour, so in two and a half hours that would give 7.5kW).
