Waste Water Heat Recovery Energy Systems

At ETS we are driven by the need to do things differently and help build a sustainable future for generations to come. Our quest to use alternative, sustainable solutions led us to developing solutions using waste heat recovery technology by harnessing the ultimate energy source – waste water.

ETS’ Waste Water Heat Recovery solutions allow for environmentally friendly, energy efficient, trouble-free transfer of energy to and from the wastewater leaving or passing almost any building in the world. By capturing heat in waste water, our Waste Water Heat Recovery systems can offset the cost of gas by 30 – 85%.

Our systems all carry an Australian Certified watermark.

The process is simple. Sewer water, which consists of everything we flush down the drain contains heat which is captured and reused.

Trouble Free

Waste Water Heat Recovery Systems have been operating in many installations around the worlds for many years. With hours of operational data in hand to refine the equipment for reliable operation, ETS can propose solutions to best suit your business and opportunity.

Harnessing Waste

Studies have found that we flush 1/3rd of the world’s energy requirements down the drain on a daily basis. With ETS’ Waste Heat Recovery Energy Systems, that energy can be captured and harnessed.

Ultimate Renewable Energy

Waste water is always being produced. There is no intermittency in its availability. And the embodied energy it contains can be captured and reused infinitely.

Innovative and Award Winning Technology

Large waste water volumes provide a great opportunity to re-use the heat energy which would otherwise literally go down the drain. ETS manufacture Waste Water Heat Recovery systems for supply to the Australia/NZ market to recycle Waste Heat energy to pre-heat incoming water at a minimal cost.
