In 2025, one in four buildings was equipped with a heat pump
In 2025, half of the residential buildings in Switzerland were heated with fossil energy sources (oil and gas). Heating oil remained the most important energy source for heating, used in 33% of all buildings. However, this share has declined steadily over the past 40 years. Gas heating was installed in 17% of buildings, with the share varying widely between urban and rural regions. In urban municipalities, 29% of buildings were heated with gas, compared with only 4% in rural municipalities.\n\nThe share of buildings with a heat pump (25%) has increased sixfold since 2000. Three quarters of the buildings constructed in the past ten years had a heat pump. Nearly one in three single-family homes (30%) had one in operation. 12% of buildings were heated with wood and 7% with electricity.
