ThermoDrain drain water heat recovery for contractors plumbers

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 Installation

It has never been so easy to install a ThermoDrain.  Designed with 3/4’’ copper water supply connections, the ThermoDrain package includes quality mechanical drain couplings for convenience.  Light and compact, the ThermoDrain is suited for a one man installation on plastic drain stacks where space is at a premium.  ThermoDrain features ultra low pressure drop and high efficiency.

What Length ThermoDrain can I install? How do I determine if it is going to fit?: For a xx" long unit, you have to cut out xx" + 0.5" from the ABS drain pipe, to fit the drain couplings you will need 1.25" of ABS at bottom and 1.25" at the top. So for a xx" long unit you will need a minimum of xx" + 2.5 + 0.5 = xx" + 3.0" of straight ABS pipe to work with as a minimum - this is considered a tight fit and requires straight cuts. example: TD342B requires a minimum of 45 inches. A length of 47 inches is preferred.

ThermoDrain is performance and safety certified to CSA 55.1 and CSA 55.2. These new standards have been developed by the Canadian Standards Association specifically for drain water heat recovery technology. 

CSA certified performance TD3xx-B
CSA certified performance TD4xx-B


Drain Water Heat Recovery - Drain pipe reduction
Also applicable to gray water recovery systems that incorporate 2" DWHR units.

The Ontario Building Code 7.4.9.1  Allows you to install a larger diameter ThermoDrain on a smaller diameter drain pipe and then return to a smaller diameter? 

Some new home construction plumbing projects in Ontario are now incorporating gray water recovery systems. These systems usually include the incorporation of a diameter drain water heat recovery unit. You are allowed to substitute a 2 or 4 system based on the Ontario plumbing code.

Ontario Building Code Reference:

7.4.9.1 No Reduction in Size
1) Except as permitted in sentence (3), no drainage pipe that is of a minimum size required by this Part for the purpose for which it is installed shall be so connected as to drain to other drainage pipe of lesser size.
2) Where a building drain connects to a stack through a wall or floor, the drain shall retain its full size through the wall or floor.
3) A Sanitary drainage pipe may be connected to a pre-engineered waste water heat recovery system that incorporates piping of a lesser size that required by Sentence (1) provided it does not convey sewage,
(a) From a sanitary unit, or (b) That contains solids.

 


ThermoDrain™ Q & A

Q - How easy is it to install?
A - A ThermoDrain can be installed by a single person in less than 45 minutes.

Q - What is included with the ThermoDrain
A - 2 rigid drain couplings, potable water ends are male 3/4" copper and each unit comes with a set of detailed installation instructions with toll free 1-888 support

Q - What length of ThermoDrain do I select?
A - Click here to view PDF on how to measure for restricted heights.

Q - Does the ThermoDrain work on Instantaneous water heaters?
A - It is compatible with all hot water heating systems including Solar. ThermoDrain is compatible with all types of plumbing systems (Iron, ABS, Copper, Pex).

Q - Does the ThermoDrain need to be insulated?
A - If the ThermoDrain is located in a humid area, condensation may form on the outside coil as is the case with all cold water lines in the home. and therefore insulating the ThermoDrain is recommended. Insulating the ThermoDrain will not significantly increase the efficiency of the unit.
