The heat pump for more output and a better future
Say goodbye to conventional fossil fuel boilers! Our HeatBooster is a next-generation high-temperature heat pump designed for heavy-duty industrial processes. What sets it apart? It's all about smarter energy and powerful performance:
Harnesses waste heat: Our powerful heat pump takes energy from waste water or steam (from 10 to 150 °C) and gives it a serious boost.
Upgrades to usable process heat: It delivers hot water from 90 to 200 °C and heat pump steam up to 200 °C and 10 bar(a).
Built on proven tech: It's powered by our proprietary piston compressor technology, ensuring maximum dependability and high efficiency—even at partial load down to 20% capacity.
Completely scalable: Start with a single unit (1–10 MWth) and scale up to 50+ MWth by combining multiple modules. This means you can invest in phases and get full system redundancy.
Why it matters: Our HeatBooster reuses energy you already have and cuts emissions.

You asked, we answered
-
How does a heat pump work?
A heat pump transfers thermal energy from a lower temperature source (like industrial waste heat) to a higher temperature sink (like process steam or hot water), using mechanical compression. HEATEN’s HeatBooster uses a piston-based compressor to efficiently generate high-temperature steam up to 180 °C or water—up to 200 °C—making it ideal for industrial decarbonization.
-
What’s the COP, and how does temperature lift affect it?
The Coefficient of Performance (COP) measures how efficiently a heat pump converts electricity into useful heat. Higher COP = more heat per unit of electricity.
A lower temperature lift (smaller gap between source and sink temperatures) generally results in a higher COP. HEATEN’s piston-based technology performs exceptionally well even at large temperature lifts, maintaining relatively high COPs where other technologies often drop off.
-
How many references do you have? Where can I see the heat pump?
You can see the HeatBooster HBL4 in operation at our Remscheid testbed in Germany.
Full commercial reference sites are expected to be online soon.
-
What is the maximum steam or water temperature on the heat sink side?
The HeatBooster delivers:
- Steam up to 180 °C.
- Water up to 200 °C.
This allows it to replace fossil-fuel-based systems in a wide variety of high-temperature industrial applications.
-
What is the maximum and minimum power output?
Current configurations cover a broad power range:
- Minimum thermal output: ~1 MWth (starting with the HBL4 model)
- Maximum system output: 50+ MWth, achievable via modular system integration (parallel, cascade, 2-stage setups)
This enables customers to start small and scale as needed, while also allowing for redundancy and efficiency optimization.
