Aluminium Electric Radiators Dry Running Ecomoney
In order to calculate the average operating cost for any electrical appliance you can use the following formula:
watts/1000 = kW x hours of operation = kW x kWh rate = cost
Watts can usually be found on the appliance nameplate.
Example: How much does it cost to operate my electric heater? An electric heater wattage is usually given on the unit itself, or with the literature that comes with it. A simple example is 1000 watts. To use this heater for 1 hour would cost based on UK Midlands British Gas standard tariff of 12.6p (September 2016) would be:-
1000 watts = 1kW x1 hour of operation = 1 kWh x 12.6p = £0.126p
This can then be calculated by hours used per day and by how many day although dependent on individual usage and of course the type of building it is being used in? Is it double glazed, insulated, type of floor and roof etc. If we take are Arlec and use this calculation it will cost the following per hour which I have rounded up to give a true refection
700 watt 0.7 x 12.6p = £0.09p per hour
900 watt 0.9 x 12.6p = £0.11p per hour
1250 watt 1.25 x 12.6p = £0.16p per hour
1500 watt 1.5 x 12.6p = £0.19p per hour
1800 watt. 1.8 x 12.6p = £0.23p per hour
The running costs of our towel rail Thermostatic and standard elements are as follows using the same formula –
Thermostatic
300 watt 0.3 x 12.6p = £0.04p per hour
600 watt 0.6 x 12.6p = £0.08p per hour
900 watt 0.9 x 12.6p = £0.11p per hour
Standard Heating Element
150 watt 0.15 x 12.6p = £0.02p per hour
250 watt 0.25 x 12.6p = £0.03p per hour
400 watt 0.4 x 12.6p = £0.05p per hour
600 watt 0.6 x 12.6p = £0.08 per hour
900 watt 0.9 x 12.6p = £0.11p per hour
