EcoInnovation Technologies Inc: ThermoDrain™
ThermoDrain™ is a Canadian manufactured drain water heat recovery unit (DWHR). These units passively extract heat from waste water to preheat incoming cold water, offering a cost effective, comfortable solution for builders to improve energy efficiency requirements.
The ThermoDrain™ DWHR unit is an internationally recognized technology used to reduce the overall energy consumption of a home by using waste energy to preheat incoming cold water. Its a cost-effective way to achieve 2 points in the BUILT GREEN® Checklist (section 1.3.10). ThermoDrain™ is 100% copper, requires no maintenance, and has no moving parts. Intertek Certified to CSA B55.2 and Verified to CSA B55.1
An actual energy model done in 2022 for a BC-based home compared the energy results using a DWHR unit as compared to not using a one:
With the DWHR, the proposed house was 30 GJ/year; Reference 58 GJ/year 47.5% lower than EnerGuide Rating System Reference House (LTRH).
Without the DWHR, the proposed house 32 GJ/year; Reference 58 GJ/year 44% lower than EnerGuide Rating System Reference House.
The difference was 2 GJ/year and 3.5% LTRH.
ThermoDrain™ is currently the most compact unit available on the market with a 42.1% efficiency at 39.5 inches. Other lengths are available. ThermoDrain was finalist for Best Green Building Product at the 2018 and 2019 NHBA - International Home Builders Show.
