THERMOWATT - State-of-the-art Technological Innovation Recovers Thermal Energy Technology

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.

• quick installation ( 5+ months)
• integration into existing heating facility is possible
• suitable for large energy demands
• easy access and maintenance
• scalable size allows for easy deployment both in urban areas and city centers, underground or in existing buildings
• system elements can be linked underground as heat-exchanged water can be conducted for longer distances

The THERMOWATT International Innovation Award winner technology is quick to install – the implementation can be as short as 6 months -, easy to access and maintain. Due to its compact size it can either be deployed next to the sewage line or at a larger distance, underground or in an existing building, and in urban areas and city centers as well. The technology can be integrated into an existing heating facility or can be established as part of a greenfield project. The system components (screening, heat exchangers and heat pumps) can be located near, or at a larger distance from each other.

As the system is scalable (MW+ systems), it can meet even large energy demands, the only limitation being the amount of available raw sewage water.

• Net Zero local CO₂ emission
• single solution for heating and cooling
• suitable for practically any cooling system
• highly efficient energy source for a heat pump-based heating/cooling system
• saving 70% on fossil energy
• the closed system does not produce any odour or hazardous waste
• wastewater composition remains unmodified ensuring stable conditions for cleaning or bioenergy production
• suitable for water heating systems up to 63 °C

The THERMOWATT technology is Net Zero, while saving 70% on fossil energy. It is a closed system, therefore, it does not produce any smell in the environment or any hazardous waste on the site. The water-water heat pump system implemented works more efficiently than air-air or air-water heat pump systems. The method does not alter the composition – neither add, nor remove anything – of the wastewater, it only changes its temperature, ensuring that conditions for cleaning or bioenergy production do not change.

Due to its virtually constant temperature, wastewater heat is one of the most efficient energy sources for a heat pump-based heating/cooling system. The technology is suitable for water heating systems up to 63 °C and for practically any cooling system. The efficiency (COP) is directly proportional to the temperature difference between the heat source and the destination.

THERMOWATT is the Ideal Solution for You

THERMOWATT’s technology is highly suitable for large property developers and operators, facilities management companies, municipalities, hospital-, hotel- and datacenter infrastructure developers and production plants. It is an ideal solution in cities with a population starting from cca. 100,000 residents.

It is efficient for operators, investors and industries with high energy consumption, such as public institutions, hospitals, large medical centers, thermal spas, sports facilities, data centers, shopping malls, wastewater plants, schools and office buildings. As sewage is renewable, the technology can use output heat otherwise lost, such as heat generated in metropolitan underground railways and production plants.
