As the inventor of the technology, Rabtherm builds the most energy efficient and cost effective heat recovery system that can be used for heating and cooling alike. The first plant was commissioned in 1999.
Rabtherm's sustainable energy solution provides heat for heating, domestic hot water and cooling for buildings or entire city blocks. It comes as a complete system for heat recovery from sewers with guaranteed heating power adapted to the customer's need. The system consists of a heat exchanger, a heat pump and a peak boiler. The heat exchanger as the core piece can be retrofitted into existing sewer pipes, or be an integrated part in a new pipe.
