Are Electric Radiators Expensive To Run
On the face of it, gas central heating looks like it is cheaper to run. In the UK, the average cost of electricity per kWh is 14.37p whereas the average cost of gas per kWh is 3.80p. However, with electric radiators , every unit of heat is used in the room. So you get 100% efficiency for the heat you are paying for at the point of use. Meanwhile, gas central heating can only offer between 80-90% efficiency. Hence you are paying for heat that is being lost through the pipes and walls of your home as it travels to your radiators from the central boiler. How To Measure Electricity Electric appliances are rated by Wattage. Energy suppliers measure electricity in kilowatts per hour. Thus 1 kWh = 1000W appliance on for 1 hour. You can start to estimate how much your electric radiator will cost. However, there are so many variable factors, that this may not give you a satisfying answer. For example a 1800W radiator equals 1.8 kilowatts. You can multiply this by how many hours you expect...
