Patented in 37 countries
THERMOWATT Kft., a subsidiary of Veolia Energia Magyarország Zrt., is a market-leading technology company with more than 17 years of experience. The company has an innovative, patented heat pump-based technology that helps energy independence and energy security by using the thermal energy of waste water, in addition to the fact that the electricity required for operation can be produced from renewable sources, even locally.
State-of-the-art solution
The THERMOWATT state-of-the-art technological innovation recovers thermal energy from communal and industrial sewage, and industrial waste heat to heat and cool buildings. The heat recovered is passed onto industrial heat pumps, while the used wastewater is led back to the sewer lines in a closed system that prevents the leakage of any hazardous material and odour.
The THERMOWATT innovative technology system’s main components are the wastewater filter, the heat exchanger and the heat pump. First, our system channels the wastewater from the main collector through a filter station removing solid particles, then to a reinforced concrete chamber located either in- or outside the building, below ground.
The solid particles are flushed back to the main collector line, so they do not need to be deposited or transported. The filtered raw wastewater enters the high-performance heat exchangers, and the heat energy recovered from the wastewater is transferred to the water-water heat pump with a compressor unit.
After implementing our proprietary and cost-effective heat utilization technology, we also undertake the operation and management of the system.
Fast and Easy Implementation
