Gas heating and heat exchangers are the most popular heating systems in new buildings. With gas heating, you are relying on a reliable technology that has been established for decades. Heat pumps are the modern, environmentally friendly alternative. But which heating is better suited to your building and your needs – gas heating or heat pump? Does a combination of the systems to create a hybrid system also make sense? To answer these questions, let’s look at the advantages and disadvantages of heating systems, their possible combinations and subsidies.
While only 1% of new buildings were equipped with heat pumps in 2000, this share increased to more than 43% in 2018. In new buildings, the heat pump has definitely won over builders, closely followed by gas heating.
Heat pumps and gas heating systems both heat the building, but they operate according to different principles. Gas heating generates heat by burning fossil fuels.
A heat pump, on the other hand, uses environmental heat and raises its temperature level with the help of electrical power.
A heat pump is particularly suitable for houses that are very well insulated. Since this is often not the case with existing buildings, there are two sensible options in these buildings:
With hybrid heating, the heat pump takes over the basic supply of heat. The gas heating switches on at peak times when the heating power of the heat pump is insufficient.
Nowadays, a new building is very well insulated. A heat pump is therefore recommended here, especially in combination with surface or underfloor heating. What if you don’t want a geothermal heat pump because it requires drilling or you can’t get a permit?
Then you can always switch to an air heat pump. A hybrid system is also an option in new buildings.
Gas heating is still justified in existing buildings. In order to plan for the future, however, you should also consider purchasing a heat pump.
The environmentally friendly heat pump is recommended for new buildings. The higher purchase costs are quickly amortised thanks to state subsidies and lower heating costs.
