1) Cut out a vertical section of drain pipe below the shower. Any type of drain pipe works with the ThermoDrain.
2) Install the ThermoDrain with the drain connectors that come with the unit.
3) Feed the bottom of the ThermoDrain coil with a cold water line.
4) Send the top of the ThermoDrain coil outlet to one of these 3 places:
NOTE: 3 is the most efficient method.
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 given length unit that is X” long unit, you have to cut out X” + 2.5″ from the drain pipe, to fit the drain couplings you will need 1.25″ of drain pipe at bottom and 1.25″ at the top.
EXAMPLE: So for a 42″ long unit you will need a minimum of 42″ + 2.5″ (1.25″ at top and 1.25″ at bottom) = 42″ + 2.5″ = 44.5″ of straight ABS pipe to work with as a minimum – this is considered a tight fit and requires straight cuts.
The ThermoDrain is the latest technology in Drain Water Heat Recovery. It has been designed for outstanding savings, home comfort and lasting performance. With its exclusive features, the ThermoDrain is simply the best drain water heat recovery technology available today!
The ThermoDrain is Intertek safety certified to CSA B55.2 & Intertek performance verified to CSA B55.1. These standards have been developed by the Canadian Standards Association specifically for drain water heat recovery technology.
Drain Water Heat Recovery – Drain pipe reduction. Also applicable to gray water recovery systems that incorporates 2″ DWHR units.
Does the Ontario Building Code 220.127.116.11 allow you to install a larger diameter ThermoDrain on a smaller diameter drain pipe and then return to a smaller diameter?
Yes! Some new home construction plumbing projects in Ontario are now incorporating gray water recovery systems. These systems usually include the incorporation of a fixed smaller diameter drain water heat recovery unit. The code allows you to use a larger diameter drain water heat recovery unit. For example, a 2″ drain system can incorporate a 3″ ThermoDrain and then go back to a 2″ drain as long as no solid waste is going through the system.

It is compatible with all hot water heating systems including Solar. ThermoDrain is compatible with all types of plumbing systems (Iron, ABS, Copper, Pex).
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.
