Central heating costs update

Central heating costs update

If you’ve switched from oil to natural gas recently, you should be feeling pleased with yourself. 




Since I last looked at the annual cost of centrally heating a house, the gap between the price of the two fuels has widened from £75 to £155. This is largely due to an increase in the price of oil but there is another factor at work. I have carried out some calculations using a new figure* for the energy density of kerosene, the fuel typically used as home heating oil. 




After the two changes mentioned above are accounted for, I estimate the yearly charge for centrally heating a fairly typical home with oil at £885 and the annual charge for gas at £730. 




There is little change in the cost of using anthracite for central heating. Interestingly if one were able to access a 90% efficient coal based boiler, solid fuel heating would be the cheapest choice for home heating by some considerable margin. 




Wood pellets remain the most expensive of the four fuels compared.

* According to the SEAI, the net calorific value of kerosene is 44,196 MJ/t.
