The heat generation process
How heat pumps work – from source to storage
Natural heat as base
Our heat pumps draw energy from natural sources: rivers, seawater, ambient air, or industrial waste heat. Even at low temperatures, these sources contain enormous amounts of thermal energy waiting to be used.
Compress heat
Using our compressor technology, we raise the extracted heat to the high temperatures required for district heating networks or industrial processes. Depending on the application, we deploy turbo compressors (TCC, based on our HOFIM technology) or reciprocating compressors (VCC, based on our RG technology). Efficiently and at large scale.
Store heat energy
The generated heat can be stored in a hot water storage and distributed through existing district heating infrastructure, enabling flexible, round-the-clock heat supply even when renewable electricity generation fluctuates.

Any refrigerant, any heat source
With references across synthetic and natural refrigerants and CO₂, and across air, seawater, and river water as heat sources, we can meet any client requirement.
Connect electricity, heating, and cooling
Large-scale heat pumps are the link between the electrical grid and the thermal grid. They enable sector coupling, using clean electricity to produce both heating and cooling for entire cities and industrial parks.
Generate carbon neutral heat
Replace fossil fuel boilers and cogeneration assets with heat pumps powered by renewable electricity, eliminating direct CO₂ emissions from heat generation.
Generate cost efficient heat
With a coefficient of performance (COP) of up to 4.0, our heat pumps deliver up to four units of heat for every unit of electricity consumed. Far more efficient than any combustion-based alternative.
Recover wasted heat
Turn low-grade waste heat from rivers, seawater, data centers, or industrial processes into usable thermal energy, energy that would otherwise be lost.
Stabilize power grids
Our heat pumps can operate flexibly, ramping from 20 percent to full load, making them ideal for grid balancing as renewable energy production fluctuates.
Store energy
Large-scale heat pumps can absorb excess cheap renewable electricity during peak production and store it as thermal energy, balancing supply and demand over the day.
Superior footprint
Our customized solutions and powerful compressors deliver best-in-class footprints and power densities, enabling even challenging brownfield integrations.
Unmatched project experience
With the largest large-scale heat pump capacity coming online, we are the market leader. We bring proven experience from delivered projects into every new conception and build.
Heat pumps for energy
Decarbonize district heating at city scale. Our large-scale heat pumps turn seawater, river water, and ambient heat into carbon-neutral warmth for entire urban networks, replacing fossil boilers with renewable electricity.
Heat pumps for industries
Cut emissions and energy costs in your process heat. Our high-temperature heat pumps recover industrial waste heat and deliver hot water and steam above 200 degrees Celsius, powering sustainable production without combustion.
FAQ
Frequently asked questions
Our systems start at 10 MWth and scale up from there. We combine flexible compressor modules from our portfolio to match each customer's requirements as closely as possible. In Esbjerg we combine two modules, in Cologne three, and in Aalborg four. This modular approach saves engineering effort and lowers cost through economies of scale.
River water, seawater, ambient air, geothermal energy, industrial waste heat, flue gases, and reclaimed drainage water. The choice depends on local availability, temperature levels, and the specific application.
Our large-scale heat pumps can deliver hot water and steam at more than 200 degrees Celsius for district heating networks and selected industrial processes.
Yes. Our heat pumps are designed to integrate with existing district heating infrastructure. In many cases, they can replace gas or coal boilers directly, delivering the same temperatures with zero direct emissions.
To maintain the optimal performance of an industrial heat pump, regular maintenance is essential. This includes scheduling routine inspections, cleaning filters and heat exchangers, checking for refrigerant leaks, and ensuring that all components are in good working condition. Additionally, monitoring the system's energy consumption and performance can help identify issues early and optimize its operation.
The COP measures efficiency. A COP of 4.0 means the heat pump produces four units of thermal energy for every unit of electricity consumed. The higher the COP, the more efficient the system, and ours achieve up to 4.0 even in winter conditions.
Yes. We act as engineering, procurement, and construction (EPC) contractor for large-scale heat pump projects, delivering everything from the compressor and heat exchangers to the building, piping, and control systems.
