Most contemporary structures in Germany are warmed primarily through the utilization of heat pumps.

Get ready for the switch, folks! A whopping 69.4% of new residential buildings erected in Germany in 2024 are gearing up to be heated with heat pumps according to the Federal Statistical Office. That's a substantial jump of over 5 percentage points from 2023! Since 2014, the use of heat pumps for residential heating has more than doubled.

These heat pumps are mostly finding a comfy spot in single and two-family houses, where they've become the primary energy source for an astonishing 74.1% of all such houses built in 2024. In multi-family houses, the number stands at 45.9%. It's no shock that the majority of new residential buildings are now warmly welcoming renewable energy sources such as ground and air heat pumps, wood from pellet heating and fireplaces, and solar thermal energy.

Interestingly, a staggering 73.9% of the residential buildings constructed in 2024 are relying on these renewable energies as their primary energy source. If we consider supplementary energy sources like wood-burning stoves, renewable energies were the heating choice for an impressive 82.3% of the new residential buildings in 2024. But natural gas still holds onto the second spot, accounting for 15.0% of the new buildings' heating energy. Unexpectedly, gas heating took up a dominant 50.7% of new buildings in 2014.

However, it's a different ball game for existing buildings. As it stands, more than half (53.9%) of existing residential buildings are still heated conventionally using gas. Renewable energies, on the other hand, play a minuscule role in the heating of existing buildings (10.2%). But the trend towards heating with renewable energies is clear in the planning of new residential buildings - a staggering 84.8% of the around 54,800 residential buildings approved in 2024 are expected to be heated predominantly using renewable methods, more specifically, heat pumps.

Despite the positive trajectory of heat pump adoption, production numbers have nosedived recently, reaching the lowest levels in the past six years. In 2024, just 162,400 devices were produced in Germany, a harsh 59.4% decrease from the previous year.

Bonus Insights!

  • Making Waves: Germany's embracing of heat pumps is part of a larger strategy to reduce carbon emissions by moving towards more eco-friendly heating technologies.
  • Showdown: The shift away from gas heating in new homes could be a foreshadowing of sweeping changes across the residential heating sector in Germany.
  • Hurdles and Advantages: The higher cost associated with heat pumps due to the electricity-to-gas price ratio is a concern, but opportunities lie in Europe's Social Climate Fund, which could potentially support the installation of heat pumps in millions of homes.
  • Perks: Heat pumps are not only a sustainable option but also offer the potential for smaller heating bills and a lifespan of 15 to 20 years.
  1. To aid this transition towards renewable-energy based heating, the German government might consider implementing a community policy that promotes vocational training in the renewable-energy industry, particularly focusing on heat pump installation and maintenance, to help address the skilled labor shortage and ensure the reliable adoption of heat pumps in new homes.
  2. As the reliance on renewable energies for heating new homes increases, it would be advantageous for financial institutions to invest in the renewable-energy sector, providing attractive financing options for homeowners looking to install heat pumps, thereby promoting energy efficiency and reducing Germany's carbon footprint.
