Securing the ThermoGeniusTM

  • Using weights attached to the lugs on the cover
  • Connect to the supports using the lugs
  • Please ask us also for the installation kit.

Recommended installation depths and clearance from the bottom and the surface

  • Water temperature remains above 4°C throughout the year (no freezing possible): heat exchanger can be installed in all layers. Installation depends on the required mean temperature.
  • Water temperature falls below 4°C during the year (freezing possible): heat exchanger is recommended only in the deep layer (constant 4°C during the year).
  • Minimum clearances: 1 m from the water surface, 1 m from the bottom, 1 m from the side.
  • Application in shallow water? Please ask us, we have the solution!


(technical data see Factsheet M1-M3)

  • Heat output: up to 22 kW at a water temperature of 5°C. (See the Service-Handbuch ThermoGeniusTM for sample performance curves)
  • Superior performance over traditional systems. In terms of the ratio of space to performance, ThermoGeniusTM is considerably more efficient than solutions involving long hoses ("thermal loops").
  • High level of efficiency thanks to convection openings with targeted guidance of the flow into the surrounding housing.
  • Better heat transfer thanks to optimised/reduced wall thicknesses.
  • Requires significantly less space than other brine heat exchanger systems, such as "lake loop" solutions featuring long hoses.
  • In contrast to previous systems, the ThermoGeniusTM heat exchanger system can run without supplementary electric heating (to prevent freezing).
  • Using a local renewable energy source cuts heating costs, fossil fuels, and CO2, protects the environment, and gives you independence.

Easy installation and maintenance

  • The ThermoGeniusTM water heat exchanger allows easy, fast, and user-friendly installation in the water - without the need for divers.
  • Various anchoring/fastening options: for example, fastened (with supports) to piling, jetties, or quays - or alternatively, anchored to the bottom of the lake or river with a balancing weight.
  • Small, compact construction, and low weight with convenient handles on the housing.
  • Low maintenance requirements. The ThermoGeniusTM does not become clogged with sediment and only the exterior needs to be cleaned from time to time.
  • Maintenance: test for leaks (annually); check for proper functioning (annually); replace the processing medium (see the instructions on the manufacturer’s data sheet); check the signage at the installation site (annually).
  • UV-resistant housing protects against mechanical effects.
  • No wear parts that need to be replaced; no spare parts necessary.

Proven quality, durability, and environmental protection

  • Durable, high-quality product made in Germany.
  • Secure, compact system with the processing medium contained in a closed system circuit.
  • All components are made from environmentally friendly, high-quality polyethylene, guaranteeing a long service life.
  • Environmentally friendly and compact solution requiring minimal space.

Connecting pipework

  • Above or below.
  • With flexible hoses.
  • At 90° angles.


  • Using a transportation cable.
  • Via suspension on a crane.

Transporting into the water, filling with processing medium, transporting in the water

  • Transporting into the water: vertically, with the connecting pipework pointing upwards. Then fill with processing medium.
  • Transport the heat exchanger to its intended location (e.g. by crane, boat, or using divers).
  • Installation can be carried out without the need for divers.
