Heat Pump Calculator
Heat pumps are one of the most efficient ways to heat your home in Denmark, offering significant savings compared to oil, natural gas, or electric heating. This calculator estimates your annual savings and payback time. The rule of thumb is 0.05 kW × m² with moderate insulation.
Types of Heat Pumps
The most common types in Denmark are air-to-water and ground-source (geothermal) heat pumps. Air-to-water pumps cost 60,000–120,000 kr to install but are slightly less efficient in very cold weather. Ground-source pumps cost 100,000–180,000 kr upfront but deliver consistent performance and typically offer 50–70% savings. For newer houses, 100 m² requires about 2.0–4.5 kW, while older houses require 5.0–5.5 kW. A standard 150 m² house typically requires 6–8 kW.
Government Subsidies
The Danish government offers subsidies for replacing oil and gas boilers with heat pumps. Check the latest grants through the Danish Energy Agency.
Placement and Sizing
The indoor unit is best placed in the basement or utility room, preferably somewhere you can close the door and not too close to bedrooms.
