ThermoDrain drain water heat recovery facts

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.

ThermoDrain Superior design

The ThermoDrain has industry leading ultra low pressure drop. 

ThermoDrain™ B Series  has been manufactured using a single 3/4" coil - ultra low pressure drop. It is the preferred new home construction model. ThermoDrain™ = no leaks and superior 3rd party verified performance.

ThermoDrain™ "A" Series 
This unit is recommended for retrofit installations due to its high efficiency in a single direction hook up. It is recommended that the A series be hooked up to send preheated water to the cold of the shower or to the hot water tank*. The pressure drop on this unit has been measured at 9.5Lpm to be 6-7 PSI. The recommended hookup would drop the pressure loss to half of this and would be mixed with hot water that has no pressure drop. The result is a total of near 1 to 2 PSI pressure drop when hooked up in the recommended cold water to the shower preheat.

Longer is not Necessarily Better......

We have turned heads in the drain water heat recovery industry by designing a compact and powerful drain water heat recovery unit with a single 3/4" coil. The idea of having to purchase a longer unit to capture more energy is a thing of the past. 

Today, you can purchase a high efficiency 42 inch long ThermoDrain unit and get all the energy savings you need without the length.

ZERO BRAZE DESIGN - UNLIKE OTHER DRAIN WATER HEAT RECOVERY DESIGNS THAT HAVE 12 BRAZE POINTS - The ThermoDrain design has no braze points. The more braze points, the higher chance the unit will leak and cause property damage.

Robust, High Quality Construction.

ThermoDrain B series is manufactured using the thickest copper walls on the market. Our coil walls are 0.045" thick and are 3/4" in diameter. 

Note: Thicker walls means a higher quality construction, a more robust unit and longer life expectancy. The larger the diameter without the splitting of flows into smaller diameters will result in an absolute silent unit with no annoying banging or hissing noises. Larger flow diameters also means no possibility of build up and blockage. ThermoDrain is the only manufacturer to have achieved a single large 3/4" design.
