ENERGY STAR® CANADA FOR NEW HOMES 2017 BUILD STANDARD 12.8 AND 17.0 ONTARIO FOR THERMODRAIN

ThermoDrain can contribute significant credits in many energy rating systems for a very low cost making it the best next step in improving building performance further. Raters should use this information to include DWHR in their building models and to calculate actual applicable credits.

The TD342B is the ThermoDrain model used for Energy Star for New Homes across Canada. It exceeds the minimum performance requirements set by Natural Resources Canada.

Core Builder Option Packages (BOP) now include ThermoDrain as an option. If your province is not listed below, you can still received significant and cost effective points through Performance Path.
