State-of-the-art innovation

THERMOWATT Technology

Our state-of-the-art heat pump-based technological innovation generates green energy from communal wastewater by directing it from the sewer lines to heat exchangers. The energy recovered by the exchangers is used for the heating and cooling of buildings with the use of heat pumps. The used wastewater is directed back to the sewer lines in a closed system that prevents the leakage of any hazardous material.

After the implementation of our proprietary and cost-effective heat utilization technology, we also undertake the operation and management of the system.

What Our Clients Say

“THERMOWATT has started the development of its unique, state-of-the-art method to utilize sewage heat long before decarbonization, and going net zero has become such a central part of our daily efforts. By now, their innovation has been turned into a solid product. They have successfully helped a growing number of companies in implementing their renewable energy-based heating/cooling system.
We at Veolia are proud to have had the opportunity to support THERMOWATT on this journey, and we wish them many more satisfied customers.”

Mr. György Palkó, CEO, Veolia Energy Hungary
“At the Budapest Sewage Works, we have been actively looking for solutions to exploit the otherwise wasted energy in sewage water and sludge. When we learned that THERMOWATT has a solution for using wastewater energy to heat and cool buildings, it was clear that we needed to assess its possibility. Besides switching to a renewable heat source, we have reached significant savings on our energy costs with the THERMOWATT system. Being able to become natural gas independent is also a huge benefit. After more than six years of experience at multiple locations, in 2022, we have decided to expand the system further.
On top of the system’s benefits, THERMOWATT has also proved itself a very reliable and trustworthy partner.”
