- Hot water heat recycling
Hot water heat recycling (also known as drain water heat recovery, greywater heat recovery, or sometimes shower water heat recovery) is the use of
heat exchangertechnology to recover and reuse hot water heat from various activities such as dishwashing, clothes washing and especially showers. The technology is used to reduce primary energyconsumption for domestic water heating. Standard units save up to 60% of the heat energy that is otherwise lost down the drain when using the shower.
The technology is fully recognized in
Canadawhere the federal ecoENERGYretrofit for homes program offers grants for installations and the EnerGuide for New Housesprogram has energy savings and energy credit calculations that it uses for new home construction.
