Running Costs

The running costs of any radiator or heater are influenced by the insulation levels of a property or room. The greater the level of heat loss within a property, the more electricity will be used by the radiator, as it has to work harder to maintain the room temperature. If the insulation levels are good then the radiator will reach the desired temperature faster and maintaining the temperature will be easier as heat loss is minimal - as a result the radiator will use less electricity.

Below is a table showing approximate running costs per hour of all of our radiators depending on different levels of insulation.

RADIATOR MODEL	kW INPUT	Newer Properties with good insulation e.g. cavity filled walls built since the mid 1970s, double glazing, loft insulation etc. Approximate cost to run per hour (pence)	Older Properties with some insulation e.g. cavity filled walls and double glazing. Approximate cost to run per hour (pence)	Old Properties without insulation e.g. solid stone walls, single glazed windows etc. Approximate cost to run per hour (pence)

3100	0.9	4p	5p	8p
3140	1.5	6p	8p	12p
3160	1.5	7p	9p	14p
3200	2.0	9p	12p	18p

4100	1.5	5.5p	7p	11p
4140	2.0	8p	10.5p	16p
4160	2.0	9p	12p	18p
4200	2.8	11.5p	15p	23p

6040	0.9	2p	3p	4p
6060	0.9	4p	5p	8p
6080	1.5	5.5p	7.5p	11p
6100	2.0	7.5p	10p	15p
6140	2.8	11p	14p	22p
6160	2.8	12.5p	16p	25p

Approximate running costs per hour assumes appropriate radiator size has been installed.
One kilowatt hour is equal to 9.9 pence (excluding VAT).
9.9 pence is based on British Gas Standard Electric Fuel Tariff and correct as at June 2011.
These running costs should be used as a guideline only and are not definitive.
Running costs will differ slightly depending on the tariff of electricity suppliers.

Heat Electric

Electric Heaters

Electric heaters are electrical appliances that change electrical energy into heat. Electric heaters consist of an electrical resistor. There are various types of electric heaters, and nearly all of them use the same physical principle to produce heat. However, they differ from each other in the way they deliver heat to the environment. Radiative electric heaters generally produce the most intense form of heat through a heating element within. Convection heaters heat the air through a heating element within by means of conduction. Fan electric heaters are a form of convection electric heaters, which include electric fans to speed up airflow.

Electric Heating

The effect of electric heating is mainly related to the production of electricity. The environmental impact of electric heating is actually dependant on the kind of electricity it consumes. Electric heating has a greater effect on the environment than heat pumps that provide the same amount of heat. Heat pumps are capable of providing larger amounts of heat, but the heat produced by electric heating is better. However, direct electric heating is generally not considered ecologically pleasant because most electricity uses fossil fuels, with up to two-thirds of energy in the fuel being lost at the power stations and in transmission losses.

Electric Radiators

Electric radiators consist of an electric resistance unit that is fixed in a reflector. Heat is generated when an electric current passes through this unit. A substantial portion of this heat is transferred from electric radiators by radiation. Initially, electric radiators were also known as ‘wet` system electric radiators. Electric radiators can be simply plugged into the usual wall sockets. For electric radiators to work efficiently, you can spur wire electric radiators into existing storage heating sockets, and then take the wire back to a unique control box. Professional electric radiator providers should obtain electric radiators for you so that you can have complete guidance about how to use them.
