Liquid gasoline boilers, extra particularly oil condensing boilers, have offered the most affordable type of residence heating, during the last 4 years, in accordance with impartial analysis.
Researchers into home heating prices, Sutherland Tables, assessed the common prices for the principle types of heating for houses and located liquid gasoline boilers got here out lowest for prices since 2020.
We take a look at the outcomes of the analysis, how oil boilers in comparison with different sorts of boilers and heating strategies, but in addition take into account the negatives of utilizing liquid gasoline boilers.
Figures ‘dispel the parable that liquid gasoline heating is an costly possibility’
The impartial findings, printed by the Sutherland Tables, evaluate the annual prices of area and water heating applied sciences for a median three-bedroom semi-detached residence.
The most recent knowledge for Nice Britain exhibits that from June 2020 to June 2024, the common yearly working value for a condensing liquid gasoline boiler was £1,231. Compared, different off-mains options equivalent to Liquefied Petroleum Gasoline (LPG) boilers have been 31% costlier at £1,620, whereas electrical storage heaters value greater than twice as a lot at £2,866.
Oil condensing boilers additionally proved to be barely cheaper heating prices than gasoline condensing boilers, which averaged £1,283, and offered cheaper working prices than renewable choices like wooden pellets or warmth pumps.
Malcolm Farrow, head of public affairs at OFTEC (Oil Firing Technical Affiliation), a UK not for revenue commerce organisation, commented: “These new figures might be welcome information for the 1.7 million UK houses that depend on liquid gasoline for his or her heating, notably at a time when we’ve all skilled a squeeze on family spending.

“Like all power costs, liquid gasoline was not immune to cost fluctuations because of the Covid pandemic and the warfare in Ukraine. Nonetheless, the four-year common dispels the parable that liquid gasoline heating is an costly possibility. Costs are additionally anticipated to remain aggressive with different fuels over the approaching months.”
(Whereas the info types a superb foundation for gasoline worth comparability, it have to be famous that heating prices are impacted by many elements. The heating calls for of a well-insulated residence, as an example, might differ fairly considerably to these an outdated residence with out a lot in the best way of insulation.)
Why have oil boilers been cheaper to run since 2020?
Liquid gasoline boilers utilizing kerosene will produce a major quantity of warmth per unit of gasoline and so gasoline consumption is comparatively low when in comparison with different types of power provide.
Gas provides will also be saved in giant tanks on the property which means gasoline will be purchased in bulk typically creating additional financial savings.
As well as, the spiralling value of gasoline and electrical energy over the interval has little question impacted findings. Electrical energy prices noticed report highs of £580.55 per Mwh in September 2022 and gasoline prices rose to £800 per therm in March 2022, in accordance with worldwide power worth reviewers Buying and selling Economics.

What are the negatives to liquid gasoline boilers and may these be solved?
Regardless of offering monetary advantages over current years, liquid gasoline boilers reliant on kerosene are environmentally damaging.
They produce excessive ranges of carbon dioxide and different greenhouse gases in comparison with cleaner power sources equivalent to warmth pumps.
Liquid gasoline boilers additionally emit pollution equivalent to nitrogen oxides (NOx) and sulfur dioxide – though oil boilers offered after autumn 2018 are required to be ‘low NOx’ – bringing dangers to air high quality. Plus, points with outdated oil tanks might lead to gasoline leaks which might result in soil and water contamination.
These issues have led to the event of different liquid gasoline provides that may take away these drawbacks while conserving costs low.
Hydrotreated Vegetable Oil (HVO), a renewable liquid gasoline, as an example, has been examined in almost 150 properties over the previous two years, reaching an 88% discount in emissions with minor boiler modifications.
Malcolm said: “While households on oil heating have loved the bottom heating prices over the previous 4 years, we should recognise the necessity to transition these properties onto a decrease carbon various to assist the UK’s internet zero commitments.
“Warmth pumps are a superb answer for some properties however, for others, renewable liquid fuels might supply a extra pragmatic and real looking selection.
“And, if the federal government corrects the present gasoline obligation disparity and implements a gasoline obligation, choices equivalent to HVO can present a long run, inexpensive answer for decarbonising buildings within the off-grid sector that at the moment depend on conventional oil heating.”
