ThermoDrain

Drain water heat recovery - Récupérateur de la chaleur des eaux de drainage

Drain water heat recovery (DWHR). ThermoDrain is a drain water heat recovery unit that recovers energy from waste water and transfers this energy to potable water before entering a water heater. It is different from other heat exchangers in that it has dual walls vented to the atmosphere so that cross contamination between wastewater and potable water is not possible. The heat transfer occurs only when wastewater is flowing down the drain while there is a demand on the hot water heater. This technology can save the homeowner up to 40% on their water heating bills. It can also triple the capacity of a hot water tank for showering. It is considered a comfortable green technology designed for shower lovers who also want to save energy. ThermoDrain is a superior drain water heat recovery technology that is manufactured in North America and comes with an industry leading 10 year warranty.

 

Manitoba Builder

The Manitoba building code amendment for 2016 requires a drain water heat recovery unit be installed on at least one shower in the home (apartment, house or condo).

The efficiency of the drain water heat recovery system must be 42% efficient.
The ThermoDrain model that meets code requirements for efficiency and safety is the ThermoDrain TD342B.

The drain water heat recovery unit can be installed in equal or unequal flow. 
Equal flow = preheated water from the ThermoDrain is sent to the cold outlet of the shower and to the cold inlet of the hot water heater
Unequal flow = preheated water from the ThermoDrain is sent to the cold outlet of the shower OR to the cold inlet of the hot water heater

The drain water heat recovery unit is not required if there is no story below the shower.
