International Wastewater Heat Exchange Systems (IWHES) announced the successful installation of a Sewage Wastewater Heat Exchange System in the 60 unit Seven35 Condominiums complex, in North Vancouver, Canada.

At 500% efficiency and an annual Greenhouse Gas Emission reduction of 150 tonnes, the system heats the domestic hot water for the development’s 60 homes and contributed to earning the condominium complex the first dual ‘green’ certification in Canada – LEED Platinum and Built Green Gold.

IWHES president – Lynn Mueller commented "We are very pleased with the performance of our 120,000 Btus per hour Sewage Wastewater Heat Recovery System and proud to have been involved with the first multi-family residential project in North America to have installed such an environmentally-friendly solution for heating and cooling."
