Research shows wood burners are more expensive for heating than gas boilers

A new study has found that household wood burners are a more expensive way to heat homes than gas boilers or heat pumps.

On Tuesday 14th November new research outlined that it is 15% more costly to use a wood burner to heat a house than a gas boiler, which shows that not only do these devices cause serious health and environmental dangers they are also too expensive to run.

The study, which was supported by Impact on Urban Health, found when a household uses a newly installed, Defra-approved wood burner for 20% of its heat, its yearly cost is between £2,204-£2,028. This works out as 24% more than a gas boiler.

In addition, the cost rises to 48% more expensive where a household uses a wood burner for 80% of its heat, costing between £2,433 – £2,614 per year.

‘This research dispels the myth that wood burning is a cheaper energy alternative whilst shining a light on the toxic effect it has on the air we breathe,’ said Rachel Pidgeon, from the charity Impact on Urban Health. ‘It’s vital that urban communities understand the connection between burning and the air pollution it creates.’

To put into perspective how dangerous wood burners are, a study that was conducted in 2022 by Professor Chris Whitty, the chief medical officer for England, found even ‘eco-design’ wood burning stoves produced 450 times more toxic air pollution than gas central heating.

Lucy Anderson, head of research at Global Action Plan, the organisation that helped carry out the research, said: ‘Pressures on household finances may be tempting more people towards burning wood because they believe it’s cheaper. But our new research demonstrates that wood burning is almost always more expensive than other formers of heating in the UK.’

Following the publication of this research and with winter vastly approaching, a series of organisations including Mums for Lungs, Global Action Plan and Impact on Urban Health are calling for better awareness of the economic, health and environmental costs of wood burning.

Jemima Hartshorn, founder, and director of Mums for Lungs said: ‘Every autumn and winter, people in towns and cities are exposed to extreme levels of toxic fumes from wood burning. This pollution affects us all, but children are particularly impacted by air pollution. It contributes to the UK’s incredibly high child asthma rates, for example.

‘It’s vital people ae aware of the strong connection between burning wood and the air pollution it causes, which has lasting, damaging effects on people’s lives.’
