The number of methods to provide heating to your accommodations is enormous. This article compares the potential running costs of various methods of heating. It excludes larger heating systems, like central heating, groundsource heating or airsource heating as these are very different and require large capital expenditure to install. These are considered in a separate article.
To get a meaningful comparison, the same power output and hence the same energy use is used in each case. The calculations are based on each heater having a power output of 3kW, and operating for 5 hours a day for about one third of a year. 3kW was chosen since this is the maximum power output of an electrical heater on a single ring main plug socket and since all the other appliances can out put the same heat power. All appliances are also assumed to be non thermostatically controlled, i.e no maximum room temperature has been set. The rate of heat loss from a room is also not considered here.
