We were advised that we were pipped at the post for this award for selection as finalists. The judges however commented on the interesting and well-written entry and the story behind the evolution of Heatback.

Energy down the drain is not a myth. We noticed on social media that sceptics are saying that the hot water temperature from the shower rose drops by as much as 15°C by the time it enters the waste plug. We believe they should get their thermometer checked over. We measured the drop to be only 3.5 to 4.7°C and these readings were from the rose through the trap to the entry pipe of the HeatBack unit. Unless you’re taking cold showers, there’s still plenty of heat to recover.

The latest monitoring from field tests show that periodic cleaning of the unit is a must if you want to maintain best efficiency. Our test showed a 10.8% increase of thermal output after cleaning. The unit had been in place for 15 months and was used daily by two people. Contrary to other designs, Heatback is the only domestic heat exchanger that has incorporated an easy cleaning facility. The frequency of cleaning will depend on the degree of use and the detergents or personal care products used. We can send before and after pictures at your request. Ask us via heatback@gmail.com
