EcoInnovation Technologies and how it all began.
In 2006, Daniel Beauchemin came across something a little strange going on in his backyard that prompted action. You see, it is not every day that you will see healthy green grass growing over a septic tank in the middle of a cold Canadian winter. What this grass represented was a significant waste of heat energy and money that was going down the drain. At this time, energy efficiency was starting to make its way into new home construction vocabulary. Knowing very well that this wasted energy must somehow be recoverable, Daniel met up with his friend Marc Fontaine to discuss a solution.

How easy is it to install?
A ThermoDrain can be installed by a single person in less than 45 minutes.
What is included with the ThermoDrain?
What length of ThermoDrain do I select?
Does the ThermoDrain work on Instantaneous water heaters?
ThermoDrain units work with all hot water heaters. ThermoDrain is compatible with all types of plumbing systems (Iron, ABS, Copper, Pex).
Does the ThermoDrain need to be insulated?
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.
Does the ThermoDrain recover waste water?
No, it simply transfers the heat from waste water by heating the drain wall. The drain wall in turn, heats up the wall of the potable water tubing and this heats up the incoming cold water. Waste water from the toilet and shower will pass through the ThermoDrain copper drain pipe in the same way your previous drain pipe would have allowed. The difference is that the copper drain pipe will transfer the heat energy through conduction heat transfer into the cold water that circulates on the outside of the drain pipe.
Where does the preheated water from the ThermoDrain go?
Three options, send it to the cold intake of the hot water heater or to the cold inlet of the shower or both. The most efficient way is to do both. Visit our Installation guide page.
Do I need to install the ThermoDrain close to the shower or hot water heater?
No, If you take a look at the NETZERO ThermoDrain unit, it will preheat cold water from 50F (10C) to 78.6 F (26C) @ 2.5 GPM (9.5 L/min). The preheated water is roughly at room temperature. Therefore the unit does not need to be close to the shower or the hot water heater.
Does the ThermoDrain drop in efficiency or cool off the preheated water if someone flushes the toilet while showering?
No, the ThermoDrain contains enough copper mass that it would not allow a fluctuation in outgoing preheated water temperature if someone was to flush a toilet while someone else was showering.
Where do I install the ThermoDrain ?
Typically, you would want to place it on the main vertical drain stack right before the waste exits the home. . The ThermoDrain does not clog any differently than a regular drain pipe. Semi solids can flow through the unit. It has been designed to replace a part of your drain pipe where both toilet water and/ or gray water flows.
Does the ThermoDrain fill up?
No, the waste water (as it flows down the pipe) forms a film on the inside of the copper drain pipe located in the center of the ThermoDrain.
What maintenance is required?
No maintenance is required, simply avoid using harsh or corrosive chemicals in the drain system that could result in copper corrosion and premature failure of the ThermoDrain unit. The ThermoDrain is built using ASTM 306 drain pipe and is designed to last for decades if used properly.
