Heat pumps more cost-effective than gas heating systems

Introduction: The switch to heat pumps

According to a study conducted by the Fraunhofer Institute for Solar Energy Systems (ISE) as part of the Ariadne project, heat pumps are a more economical alternative to new gas heating systems in detached houses and apartment blocks in the long term.

Economic efficiency and environmental friendliness

Energy efficiency and CO2 emissions

The cost-effectiveness of the various heating technologies is largely dependent on the price of CO2. The researchers anticipate a CO2 price of between 95 and 141 euros per tonne in 2030 and 220 to 309 euros in 2040, making heat pumps particularly attractive.

Cost analysis: acquisition and operation

The study analyses the current costs for purchase and installation as well as the future operating costs for various heating systems. Heat pumps, particularly in combination with photovoltaic systems, prove to be a cost-effective solution.

Case studies: Single-family and multi-family houses

Single-family homes: cost savings through photovoltaics

In detached houses, the overall costs can be further reduced by using photovoltaics for self-consumption, making heat pumps even more attractive.

Apartment blocks: efficiency even without refurbishment

Heat pumps are also a cost-effective alternative to new gas heating systems in apartment blocks, including unrenovated buildings.

Conclusion: Heat pumps as a sustainable solution

The results of the study emphasise the importance of heat pumps as a sustainable and economically advantageous heating solution. They are an important component of the energy transition and contribute to a more environmentally friendly future.
