Energy Generation with Large Heat Pump Systems

Solutions for large heat pump systems

More than 57 % of Germany’s end energy demand is used for generating heat: Large heat pump systems are the solution for tomorrow’s sustainable energy supply. By harnessing ambient heat and waste heat they supply buildings and industrial processes sustainably with heat – with thermal outputs of up to 150 MW and temperature lifts as high as 200 °C, far exceeding common domestic heat pumps. This is how climate-friendly, efficient heat becomes reality.

Sustainable heat generation: How to benefit from large heat pump systems

30 % of district heat is to be generated from renewable sources or waste heat by 2030. By 2045 heat supply is to be fully climate-neutral – as per the Wärmeplanungsgesetz, Germany’s Heat Planning Act.

Already today, large heat pump systems meet the preconditions for reaching these targets reliably.

They enable a heat supply that is sustainable, efficient and future-proof – and that offers distinct economical and environmental benefits:

Sustainable heat and reduction of CO₂

Large-scale heat pump systems use ambient and waste heat rather than fossil fuels. Depending on the power mix and system design, CO₂ emissions can be lowered significantly in this way. This advances your decarbonisation strategy and helps you meet legal requirements.

Profitability through efficiency

From 1 kWh of electricity consumed, large heat pumps produce several times the useful heat. The multiplication factor depends on the specific system. High efficiency and attractive subsidies durably lower your total costs and future-proof your heat supply for a long time to come.

Scalability and operating reliability

Every heating network is unique – and requires solutions that can be adjusted with precision. Modular in design, large heat pump systems can be upscaled flexibly to your needs – from building complexes to district heating networks and through to industry. They are easy to integrate in existing networks and offer a proven, reliable technology for a dependable supply.
