Heating
Replace your fossil heating with a heat pump or wood boiler: up to CHF 15,000 in subsidies and -70% on your bills.
In Switzerland, heating represents 60 to 70% of a home's energy consumption. If your system still runs on oil or gas, you face constantly rising costs, exposure to increasingly strict cantonal regulations, and the loss of several thousand francs in subsidies still available today.
Modern solutions: air-to-water or geothermal heat pump, wood pellet heating, smart hybrid systems. Cumulative subsidies up to CHF 4,000–15,000 depending on the canton. Up to 70% savings on your heating costs. Payback in 5 to 10 years, property value increase of +5% to +15%.
In several cantons, fossil heating replacement will become mandatory in the medium term. The longer you wait, the more subsidies shrink, costs rise, and delays grow. Today: a strongly reduced net cost thanks to subsidies. Tomorrow: mandatory without support.
