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.
When looking at the HOT2000 modelling baseline (reference house), unlike many technologies, there is no baseline for drain water heat recovery (DWHR). This means, when one is added, it offers pure energy savings towards your target.
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.

This product may help earn points under the following checklist item:
1.3.10 Install drain water heat recovery (DWHR) units on the main drain stack to recover heat from shower drain water. DWHR units must be CSA certified to B55.1 and B55.2: 1 point for units less than 42% efficient and 2 points for units greater than, or equal to, 42% efficient. Additional point if unit is fully insulated (1 point).
