Welcome to the ThermoDrain installation guide. In this section, you will find the information that will make your drain water heat recovery unit installation straightforward. It includes downloadable installation instructions, images to assist in understanding the best possible configuration. The ThermoDrain is easy and simple to install due to its exclusive patent pending features such as the factory installed crimp PEX fitting that will make your installation effortless. Each unit comes with drain couplings designed for an easy and fast installation.
A THERMODRAIN INSTALLATION IS STRAIGHT FORWARD
Factory installed crimp PEX fittings
ThermoDrain comes with preinstalled crimp style PEX fittings. This patent pending option makes the installation of your new unit easy and fast. No soldering required. Simply line up the PEX lines and crimp them.
Watch this video to learn more about PEX.
If you are not using crimp style PEX fittings, then the non-PEX ThermoDrain option is for you.
High Quality drain couplings
ThermoDrain comes with a high quality drain coupling that ensures a fast and easy installation.
CONNECTING THE THERMODRAIN
A ThermoDrain installation takes on average, 20 to 45 minutes and $30 to $50 of additional part.
ThermoDrain comes with optional factory-installed PEX fittings. All units come with quality mechanical drain couplings explicitly designed for the ThermoDrain. Light and compact, the ThermoDrain is suited for a one-person installation on plastic drain stacks where space is at a premium. ThermoDrain features ultra low-pressure drop and high efficiency.
SIMPLE INSTALLATION STEPS FOR THE THERMODRAIN
The drain connection
1. Cut out a vertical section of the drainpipe below the shower. Any drain pipe works with the ThermoDrain Refer to ThermoDrain installation instructions for measurements.
2. Fasten the drain connectors to the ThermoDrain and to the drain pipe. These will seal the top and bottom of the drain connection.
The coil connection
1. Connect the bottom of the ThermoDrain coil to a cold water supply line (this is the inlet).
2. Connect the top of the ThermoDrain coil (this is the exit) in any of the following three configuration options;
(Refer to diagrams below)
Option 1. The cold water line of the shower
Option 2. The inlet of the hot water tank
Option 3. Alternatively, both 1 and 2
NOTE: option 3 is the most efficient method

PERFORMANCE VERIFIED AND SAFETY CERTIFIED
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.
ThermoDrain Q & A
A ThermoDrain can be installed by a single person in less than 45 minutes.
Two easy to install drain couplings and instructions. If you ordered the PEX option, these will be crimp PEX type fittings that will be factory installed onto the unit.

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.
