De'Longhi Dragon 3 TRD0820T Oil Filled Radiator with Timer, 2 kW

Product Information

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. 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.

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 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. But as people have been saying, if its 2k then about 30p an hour if its on max power non stop for that hour. I have three oil filled rads (hardly used now since we moved house), with the best one being a DeLonghi Dragon 3, which is a cracking bit of kit - - when our boiler failed in the last house, that one radiator kept our living room (25ft x 15ft) and staircase leading off it lovely and warm; currently, it is employed in our outhouse/utility room purely to keep the freezer and water pipes happy, and is sensitive enough to keep the room temperature at around 5 degrees.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. That's assuming it's thermostat is set to max and the heater never switches it's heating element off during that time.

also does anyone know if the oil filled heater is more cost effective than a storage or basic electric heater? If you check your bill you will be able to find out how much you are paying per unit of electricity. So not very surprisingly at all is that if you have insulation and double glazing it will hold at that temperature longer and so cost less than if you open all your windows. 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. As mentioned earlier, the maximum that the heater will use is around 2 units of electricity in an hour (2kwh) - for me that's 12.Most (if not all) have built in thermostats, and the good ones are actual room temperature ones which allow you to set and forget.

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? Halogen heaters; one of the cheaper ones to run, but the heat is extremely directional and doesn't really heat the room at all.

When it has heated the oil to the temperature you set, it will switch off and cost nothing until it cools to a lower temperature. 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? All electric heaters have the same efficiency and will give out exactly the same amount of heat per unit of electricity used.

However the maximum the heater will cost will per1 unit of electricity per hour, per kilowatt of heat. Oil or fluid filled radiators; these are as near to central heating as you could reasonably ask from a portable heater. 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.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. It is very difficult to accurately determine how much it costs to run a heater within your own environment.
