Oil filled radiators are more economical to run because they retain heat longer and power demand through the temperature control is called upon less frequently.

so i wonder when the heater reaches temp the amount of electric used by it would be likley to drop as its probably not using max power as its all ready warm? If you have gas central heating NEVER get an electric heater. Electric heaters are about 3 times more expensive to run. The heater may use slightly more energy when the oil is cold because the element will have a lower resistance, but I doubt that makes much of a difference. Electric heaters heat only the room you are in and not the entire house, providing extra heat only where required and helping to optimise energy consumption. The cost per kilowatt-hour seems to vary quite a lot depending on who you sign up with and how much you use per month.If the heater has a dial for setting the heat level or temperature, the way this is set will alter the amount of time the element is actually switched on and will certainly affect the cost of running the heater. It is very difficult to accurately determine how much it costs to run a heater within your own environment. It depends largely on the type of house, size of room and quality of insulation. However the maximum the heater will cost will per1 unit of electricity per hour, per kilowatt of heat. For example, if you have a1500 W heater the maximum it will use is 1.5 energy units per hour. Halogen heaters; one of the cheaper ones to run, but the heat is extremely directional and doesn't really heat the room at all. so I wonder when the heater reaches temp the amount of electric used by it would be likely to drop as its probably not using max power as its all ready warm?

also does anyone know if the oil filled heater is more cost effective than a storage or basic electric heater? Storage heaters; the idea to use cheaper off peak electric is OK, but when I had these I found that the heat had discharged from them by mid afternoon, which then meant that there was little or no heat left for the evenings Both the convection heaters and oil filled heaters cycle on and off, so whilst the radiator may be on and plugged in, they are not consuming electricity all the time - - how much they do consume is entirely driven by how high you have them set. or 3 bar electric fires; not bad at heating a room, but hellishly expensive to run as they are burning 2 or 3kw constantly while they are on.

They are really good. When the thermostat trips out, the oil cools down gradually, you don't get the "peaks and troughs" of fan heaters or panel heaters - or worst of all halogen/radiant heaters. i just bought a new heater its a 2kw delongi dragon oil filled one and i would like to know if anyone can tell me how to work out the running cost per hour or so. any info will be great thanks
