Different Heating Options in Denmark
In Denmark, residents have various options when it comes to choosing how they'd like to heat their homes. The country's emphasis on energy efficiency and sustainability means many of these options are not just effective in terms of heat production but also environmentally responsible. Here's a closer look at some of the most common heating methods in Denmark.
District Heating (Centralized Heating)
District heating is one of the primary heating sources in Denmark, especially in urban areas. This centralized system provides heat to multiple residences and buildings by distributing hot water or steam from a central source. The method is both efficient and sustainable, primarily when generated from renewable energy sources.
Natural Gas Boilers
Natural gas boilers are another prevalent choice among Danish households. These systems use natural gas to heat water, which is then circulated through radiators or underfloor heating systems to warm the house. It's a straightforward method, but its sustainability is contingent upon the source of the natural gas.
For those who prefer a more straightforward and portable heating solution, electric heaters are available. These devices convert electric energy directly into heat.
While they might not be the primary source of heat in most Danish homes, they can be ideal for additional warmth or for spaces not connected to centralized systems.
Heat pumps are becoming increasingly popular in Denmark due to their energy efficiency. These devices extract heat from the outside air (even when it's cold!) and use it to warm the interior of a house. There are two main types: air-to-air and air-to-water, each serving a slightly different purpose but both providing a sustainable heating solution.
Biomass Boilers and Pellet Stoves
Biomass boilers and pellet stoves use organic materials like wood chips or pellets as a fuel source. These systems are considered renewable as the materials used are either waste products or can be replanted.
When burned, the biomass releases heat, which warms the water, subsequently distributing heat throughout the house. This method is carbon-neutral, making it another eco-friendly option in Denmark.
District Heating: Denmark's Primary Heating Source
District heating, a remarkable feat of engineering and community planning, stands as one of Denmark's proudest sustainable achievements. With a history that spans over a century, this system has evolved to meet the needs of a growing urban population while staying aligned with the country's green objectives.
What is District Heating and How Does It Work?
At its core, district heating is a centralized heating system that serves multiple homes, businesses, and buildings in a particular area. Instead of each building having its individual boiler or heat source, district heating uses a large, centralized facility to produce heat. This heat, typically in the form of hot water or steam, is then distributed through a network of insulated pipes to connected buildings.
The central heat source can vary: it might be a dedicated heating plant, a waste-to-energy plant, or even a combined heat and power plant (CHP) that simultaneously produces electricity. This versatility ensures optimal use of resources and minimizes waste.
Benefits: Efficiency, Sustainability, and Cost
One of the main advantages of district heating is its efficiency. By centralizing heat production, the system can achieve economies of scale, resulting in a more effective generation and distribution of heat.
District heating often employs renewable energy sources, such as geothermal energy, wind, or biomass. Additionally, many of the modern systems in Denmark harness waste heat — for instance, excess heat produced by industrial processes or electricity generation. This approach aligns perfectly with the country's dedication to sustainable practices.
While the initial connection to a district heating system might come with a cost, the overall expenses in the long run are often competitive, if not cheaper, than other heating methods. The system's efficiency translates to reduced energy consumption, which, in turn, leads to savings on heating bills.
How to Connect to District Heating Systems
For foreigners living in Denmark, the process of connecting to a district heating system largely depends on the location of their residence. Most urban areas, especially in larger cities, are already well-serviced by district heating networks.

Natural Gas Boilers
Natural gas boilers, though not as predominant as district heating, are still a prevalent heating choice in various parts of Denmark. These systems harness the energy from burning natural gas to heat water, which is then circulated through radiators or underfloor systems, effectively warming the interior spaces of homes and buildings.
Overview and Functionality
Natural gas boilers operate on a straightforward principle. They burn natural gas, which produces heat. This heat is used to warm up water in a closed system.
The hot water or steam generated is then circulated throughout the home or building through a series of pipes, radiators, or underfloor heating mechanisms. Once the heat dissipates from the water, it returns to the boiler to be reheated, thus completing the cycle.
Advantages and Disadvantages
- Consistent Heat Supply: Natural gas boilers provide a continuous and consistent heat supply, ensuring comfort even during the coldest months.
- Efficiency: Modern natural gas boilers are designed to maximize efficiency. High-efficiency models can convert nearly all the fuel they burn into usable heat, minimizing waste and reducing heating costs.
- Compact Design: These boilers are generally compact, allowing them to fit even in homes with limited space.
- Reliance on Fossil Fuels: Natural gas is a fossil fuel, and burning it releases carbon dioxide into the atmosphere. While it's cleaner than some other fossil fuels, it's not as sustainable as renewable energy sources.
- Fluctuating Prices: The cost of natural gas can be volatile, depending on global market conditions. This fluctuation can impact heating expenses.
- Installation Costs: Setting up a natural gas boiler system, especially in residences not previously equipped for it, can involve a considerable initial investment.

Clean the System
Over time, sediments and other impurities can accumulate in the boiler and the pipes. Flushing the system periodically can help prevent blockages and maintain efficiency.
Monitor the Flame
A healthy boiler flame should be blue. If it turns yellow or orange, it could indicate incomplete combustion and potential issues. In such cases, consult a technician.
While Denmark's primary focus revolves around centralized and renewable heating solutions, electric heaters serve as a versatile alternative, especially in situations where primary heating might be insufficient or unavailable. These heaters offer a simple and direct approach to heating, converting electric energy into warmth.
Types of Electric Heaters Available in Denmark
In the diverse market of electric heaters, various models cater to different needs. Some of the most common types include:
These heaters warm the air directly around them. As the hot air rises, it displaces the cold air, which then gets heated in turn. This circulation process results in an evenly heated room.
Radiant or Infrared Heaters
Instead of heating the air, radiant heaters emit infrared radiation that directly warms objects and people in its path. They offer quick heat and are ideal for warming specific areas or people rather than an entire room.
These are electric heaters that use oil as a heat reservoir. They heat the oil, which then circulates through the radiator coils, emitting warmth. While they might take longer to heat up, they retain heat for an extended period, even after being turned off.
These heaters combine elements of convection and radiant heating. They use a fan to blow air over a heated element, distributing the warmed air throughout the room.
Benefits: Portability, Ease of Use
One of the standout advantages of electric heaters is their portability. They can easily be moved from one room to another, making them perfect for targeted heating or spaces that lack a fixed heating system.

Electric heaters convert almost all the electric energy they consume into heat. However, it's worth noting that producing electricity, especially if it's from non-renewable sources, might not be as efficient or sustainable as direct heating methods.
Electricity prices in Denmark can be relatively high compared to other energy sources. Using electric heaters as a primary heating source throughout the winter might result in increased utility bills. However, for occasional use or supplemental heating, the cost might be justifiable.
Heat pumps, a symbol of modern and sustainable technology, are steadily gaining traction in Denmark's heating scene. They operate on the principle of extracting heat from one source and transferring it to another.
Given Denmark's commitment to sustainability, it's no surprise that heat pumps, with their energy efficiency and eco-friendly attributes, are becoming a preferred choice for many.
How Heat Pumps Work
Heat pumps function by moving heat rather than generating it. Using a refrigeration cycle similar to that of a refrigerator but in reverse, they extract heat from the outside environment and bring it inside. Surprisingly, even during cold weather, there's still ambient heat present in the air, which these devices can harness.
The two main types of heat pumps commonly used in Denmark are:
- Air-to-Air Heat Pumps: These systems extract heat from outdoor air and transfer it to indoor air. The process can be reversed in the summer, offering a cooling solution as well.
- Air-to-Water Heat Pumps: These are designed to heat water, which can then be used in radiators, underfloor heating systems, or even domestic hot water supplies.
Advantages of Heat Pumps
Heat pumps are remarkably efficient, as they only require electricity to run the compressor and circulate the refrigerant. The heat they transfer is essentially "free" energy sourced from the environment.
By relying on ambient heat and reducing the need for fossil fuels, heat pumps contribute to a reduction in greenhouse gas emissions.
While the initial investment can be substantial, the operational costs are often lower than conventional heating systems, especially if replacing older, less efficient systems.
Heat pumps can serve both heating and cooling needs, making them suitable for year-round use.
