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 for your home today!
How the ThermoDrain™ Works
The ThermoDrain™ consists of a single copper potable water tube wound around a central copper drain tube. Waste water flowing down the drain transfers heat to the cold water moving upwards through the coil. The preheated water from the ThermoDrain™ then feeds the water heater and/or the cold side of the shower thus requiring less energy. The single coil 3/4" design offers very low pressure drop and high efficiency.
Comfort for the Entire Family
On average, 20% of a homeowner’s energy bill is from heating water. Growing energy costs requires that we stop wasting precious heat down the drain. The ThermoDrain™ will save on utility bills year after year, while adding value to your home.
The comfort of almost endless hot water is here! Heat energy recovered by the ThermoDrain™ will increase threefold the capacity of a water heater rendering cold showers a thing of the past!
With no moving parts or seals, no required maintenance, and a ten year limited warranty, the ThermoDrain™ ensures piece of mind, efficiency and savings.
Eco-Friendly and Durable
As we take conscience of our environment and the effects we have on it, we all want to play a role in sustainable development. Innovative solutions such as the ThermoDrain™ will reduce a home’s carbon footprint by one ton of CO2 per year, the equivalent of what one acre of pristine forest can remove.
The ThermoDrain is also the perfect complement to your home’s water heating system. Combined, they offer very high energy efficiency and significantly reduce your home’s environmental impact. The ThermoDrain™ is 100% recyclable and is an environmentally responsible product.
The ThermoDrain™ is the best DWHR unit on the market today! You may select your model from the following table. Your selection should take into account the available length of the 3” drain pipe where the unit will be installed as well as the efficiency you wish to obtain. The models proposed are all suited for residential installation and should be located on the vertical drain stack that services at least one shower and most of the appliances using hot water.
ThermoDrain™ - 3 simple installation options
In a new construction, the preferred installation configuration is to send preheated water from the ThermoDrain™ to the water heater's cold supply and to the cold water supply of the shower because it provides the most energy savings. In renovation projects, often limited access to the bathroom plumbing or the water heater makes it more practical to use the other two configurations as shown below.
ThermoDrain gives you a high rate of return on your investment....
The ThermoDrain is estimated to last over 50+ years. The copper alone will most likely be worth more at the end of its life cycle than what you paid for it at the beginning. It can be also be recycled into another ThermoDrain for another 50+ years of service.

As a homeowner, you may be interested to know that hot water is the 2nd highest energy user after home heating. Growing energy costs requires that we stop wasting precious heat down the drain. The ThermoDrain™ is the most cost effective way to save on utility bills year after year, while adding value to your home.
The ThermoDrain™ is perfectly suited for high flow multiple shower heads, rain showers or wall mounted body spray's as it offsets the high running costs of these devices.
If replacing you standard shower head with an ultra low flow model is what you had in mind but fear the lack of flow from these, consider that a ThermoDrain™ will provide the same energy savings without having to compromise.
The following provides savings scenarios with the use of a ThermoDrain™ for different energy sources and costs.
Natural gas water heater + ThermoDrain™ -
Annual cost savings: $85 to $139
Oil water heater + ThermoDrain™ -
Annual cost savings: $133 to $217
Electric water heater + ThermoDrain™ -
Annual cost savings: $87 to $278
Savings depend on ThermoDrain™ model and configuration and water usage.
The ThermoDrain™ is installed vertically on the main drain stack in order to capture most of the hot waste water used. The preheated potable water from the ThermoDrain™ may be fed in a variety of configurations to either or both the water heater and cold side of the plumbing fixtures using hot water. No maintenance is required, it has a very low pressure drop and has been designed with outstanding efficiency. The ThermoDrain is easy to install and takes no more than 45 minutes with some plumbing experience.
Safety First - ThermoDrain is CSA certified
EcoInnovation has been working with the CSA (Canadian Standards Association) standards committee to develop a the only 3rd party verification standards for performance and safety for drain water heat recovery systems. The ThermoDrain is CSA certified to these standards.
