What is Wastewater Heat Recovery or Wastewater Energy Transfer?

Right below the ground, running through the sewers, is a hidden and seldom used source of energy: domestic or municipal wastewater with a temperature of 60°F–70°F or 15°C – 20°C all year round. Depending on the sewer characteristics, the constant supply of wastewater can be an ideal energy source for both heating and cooling buildings or industrial processes.

Using Noventa’s patented HUBER ThermWin® wastewater energy transfer system, energy is either extracted from the sewer to supply heating to buildings in the winter or heat is rejected to the sewer to provide cooling to buildings in the summer. High coefficients of performance, or COPs, are achieved using Trane heat pumps in combination with our patented HUBER ThermWin® technology. Gas and electricity consumption are significantly reduced, providing meaningful environmental as well as financial benefits for the end users and the community as a whole.

The HUBER RoWin® Heat Exchanger – the key component of the HUBER ThermWin® System – has been specifically developed to extract the enormous energy potential hidden in wastewater and other difficult media. It is the product of over 100 years of HUBER ingenuity and experience dealing with the corrosive elements of sewage – and it is exclusively licensed to Noventa.
