Heating law: Four misunderstandings about gas and oil heating systems

There are a total of eleven widespread misconceptions in connection with the Building Energy Act (GEG), often referred to as the Heating Act, as reported in the 12/2023 issue of "Finanztest". Here we shed light on four key misconceptions and clear them up:

1. Misconception: Old oil and gas heating systems may no longer be operated

The correct answer is: A blanket ban will not come into force until 2045. Until then, there are numerous exceptions and transitional regulations, depending on the heat planning of the municipalities. The installation of gas and oil heating systems will continue to be permitted. From 2024, however, it must be ensured that such heating systems use increasing proportions of renewable energy from 2029. For the transitional period of five years, any type of fossil fuel heating system can be installed.

2. Misconception: Heat pumps must always be installed in new buildings.

This is not true: All options that meet the so-called 65 percent rule, i.e. are powered by 65 percent renewable energy, are possible in new-build areas. For non-new builds, it is theoretically also possible to install a fossil fuel heating system, but this could increase the construction costs due to the chimney required, according to "Finanztest".

3. Misconception: An old house, regardless of whether you buy it or inherit it, must be comprehensively renovated.

No one is generally obliged to do this. In a few cases, such as a lack of insulation on the top floor or a heating system that is over 30 years old, new owners must take action within two years. However, a change of ownership is a good time to carry out the necessary renovation measures.
