We Have a Heating Plan
As a consumer, it can be difficult to know what your options are when switching to greener heating. That’s because geography determines what’s possible—and what the best and most cost-effective solution is.
That’s why Sønderborg Municipality, in collaboration with local utility companies and ProjectZero, has developed a comprehensive heating plan for the entire Sønderborg area. The plan maps out the best solution for the approximately 3,600 households that will need to replace their oil or gas boilers in the coming years.
By 2030, oil boilers will be completely phased out. And by 2035, gas boilers will follow. This is part of the Danish government’s climate strategy—and a step toward reducing reliance on Russian gas.
In the Sønderborg area, we are even more ambitious. Our goal is to phase out all oil and gas boilers by the end of 2029. These systems account for a significant part of our CO₂ footprint. On average, an oil boiler emits 5,600 kg of CO₂ per year, while a gas boiler emits 3,800 kg.
In addition, according to the Danish Energy Agency, most households with oil or gas heating can expect lower heating bills when switching to district heating, local heating, or a heat pump.
For most households in the Sønderborg area, district heating is the best alternative. In areas where district heating is not financially viable, homeowners should either switch to an individual heat pump or a shared local heating solution.
Local heating is not connected to the district heating network but can, for example, be a shared heat pump or a thermal network that an entire village can connect to.
On the map, you can see which areas are being considered for either district heating or local heating. If you live outside the highlighted areas, the recommended solution is to switch to a heat pump.
