Contrary to the ambitions to phase out gas in private homes, Danes continue to install gas boilers. Last year, 4,241 gas boilers were installed in Denmark. This corresponds to 11 boilers installed every day – almost the same number as the year before. This is shown by figures from the Danish Safety Technology Authority, which Energy Supply has been granted access to.
During the same period, almost 22,000 gas boilers were scrapped. This means that a new gas boiler was installed for every five that were scrapped. The thousands of new gas boilers are being installed, despite the fact that a broad majority in the Danish Parliament has decided that all private gas boilers must be phased out by 2035.
- It is a blatant disaster, says Brian Vad Mathiesen, professor of energy planning at Aalborg University.
He points out that Europe is still heavily dependent on imported fuels, including natural gas, which poses a major risk for gas boiler owners.
- With the current geopolitical situation, gas prices could quickly rise again. Either due to the obvious tensions or due to increased activity in the Chinese economy, he says.
Marie Münster, professor of energy system analysis at DTU, calls the development regrettable.
- Gas should be used in sectors that cannot be electrified, and for backup in the electricity system – not to produce lukewarm water in households, she says.
She emphasizes that it is positive that more gas boilers are still being dismantled than are being installed.
The statement covers both newly produced boilers and recycled boilers and does not distinguish between new installations and replacements for old gas boilers.
259,000 homes are heated by gas boilers
The political decision to phase out gas boilers for space heating was made in 2022, after the energy crisis sent gas prices skyrocketing and left gas boiler owners with sky-high heating bills. Since then, the political stubbornness has been tempered.
Minister of Climate, Energy and Utilities Lars Aagaard (M) noted in the spring of 2025 that it was "not that important" whether the heat came from district heating, heat pumps or green biogas.
At that time, the expectation was that there would be 100 percent biogas in the Danish gas network by 2030 at the latest. However, the government's climate projection from this summer reported that this would not happen until 2032 at the earliest.
- The government's position has become somewhat more unclear. The population does not receive a clear signal about what to do if their gas boiler stops working, says Marie Münster.
According to the national gas distribution company Evida, almost 259,000 homes are currently heated by a gas boiler.
