We cover here only spontaneous water heaters, they are generally fueled by either natural gas or electricity; however there are some units on the market using LPG, especially for caravan applications there are units that use butane or propane in gas cylinders.

Central Heating

central heating cost comparisonsmoneyGenerally central heating is the most energy and cost efficient way of heating a home, particularly those systems using fuels that are burned in a boiler. It is also very often one of those areas where you have the least control. Factors outside of your control may include:-

Heating Units

cost of running heatersmoneyThe 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.
