The choice of heat source has a major impact on your energy bills, carbon footprint and property value. ## Who it is relevant for Readers and agents that need a reliable concept definition. ## What FT can prepare - Connect the concept to related pages, sources and practical use. ## What the architect validates - How the concept affects a concrete project or decision. ## Definition text The heating system is the technical system that produces heat in your home — either directly (heat pump, boiler) or via a district heating network. It is one of the most important variables for your energy bill and carbon footprint. ## Why does it matter to you? The choice of heat source has significant consequences: - **Running costs:** District heating and heat pumps are typically cheaper to run than gas or oil - **Carbon footprint:** Electric heat pumps have a low CO₂ impact — and it's falling as the grid gets greener - **Property value:** Homes with heat pumps or district heating typically sell at a premium - **Regulations:** Denmark is phasing out oil and gas boilers, with requirements affecting various building types from 2026–2030 ## The main heating options in Denmark **District heating (fjernvarme):** Hot water delivered via pipes from a shared heating plant. Easy to operate, competitively priced, and typically based on biomass or waste heat. Widespread in Danish cities. **Air-to-water heat pump:** Extracts heat from outdoor air and transfers it to the heating system. Low running costs, but requires an investment of DKK 60,000–150,000. **Ground source heat pump:** Extracts heat from the earth via buried pipes or boreholes. Even more efficient than air-to-water, but requires space for drilling. **Gas or oil boiler:** Traditional fossil fuel solution. Higher CO₂ impact and politically being phased out. **Wood pellet boiler:** Renewable alternative to gas/oil. Requires storage space for pellets. ## Frequently asked questions ### Do I need to register my new heat pump in the BBR? Yes. Heating installations are registered in the Danish Building Register (BBR), and changes must be reported to the municipality. ### Can I freely switch heat sources? Mostly yes. However, in areas served by district heating, the municipality may require connection to the district network. Always check with your municipality before investing in a new system. ### What is the COP of a heat pump? The COP (Coefficient of Performance) indicates efficiency — typically 3–4, meaning the pump produces 3–4 kWh of heat for every 1 kWh of electricity consumed. ## Sources and basis - [Fremtidens Tegnestue methodology](https://fremtidenstegnestue.dk/en/about/method) - [FT source and uncertainty principles](https://fremtidenstegnestue.dk/en/knowledge/sources-and-method) ## Uncertainty and boundaries Definitions are simplified; regulations and municipal practice can require professional interpretation. ## Next step Read related concepts or project pages. ## Related pages - [Energy Labels in Denmark](https://fremtidenstegnestue.dk/en/knowledge/concepts/energimaerke): related-concept - [Retrofit Insulation](https://fremtidenstegnestue.dk/en/knowledge/concepts/efterisolering): related-concept - [BBR — Danish Building and Dwelling Register](https://fremtidenstegnestue.dk/en/knowledge/concepts/bbr): related-concept - [BR18 — Danish Building Regulations 2018](https://fremtidenstegnestue.dk/en/knowledge/concepts/br18): related-concept - [Concepts](https://fremtidenstegnestue.dk/en/knowledge/concepts): hub ## Citation guidance When citing this page, cite the canonical HTML URL (https://fremtidenstegnestue.dk/en/knowledge/concepts/varmeinstallation) as the public source and use this Markdown URL only as the agent-readable representation.
