The wisdom of using an electric heater depends on the per kilowatt cost in your region. 1  If your heater has a 1000 watt rating and your cost of electricity is $0.15/Kwh your cost to operate for one hour would be $0.15. 2  If the element is activated 10 hours out of every 24 hours your cost per day would be $1.50.
Best Answer: Electricity costs about 20pence per unit and 1 unit is one Kw. So 2 Kw will cost you 2 units. Electricity is charged by Kw per hour or KwH. so for 2 hours your heater will cost 80 pence.There will be a slight saving on this as the heater will have a thermostat on it and it will cut in and out for a few minutes over an hour. Hope this helps.est Answer: Electricity costs about 20pence per unit and 1 unit is one Kw. So 2 Kw will cost you 2 units.
