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 IT 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.
LOWER ENERGY CONSUMPTION = SAVINGS!
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. On average, 20% of a homeowner’s energy bill is from heating water.
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.
Some Technical Stuff
How much of an temperature increase will I see using the ThermoDrain?
TD342B 42.8% efficient
Drain water temperature 100 F
Cold water temperature 50 F
DELTA T = 50 F
Temperature increase = 50F x 42.8% = 21.4F
50 F cold + 21.4 F ThermoDrain increase = 71.4 F ThermoDrain exit
TD360B 51.5% efficient
Drain water temperature 100 F
Cold water temperature 50 8
DELTA T = 50 F
Temperature increase = 50F x 51.5% = 25.75F
50 F cold + 25.75 F ThermoDrain increase = 75.75 F ThermoDrain exit
COMFORT - LONGER SHOWERS
The comfort of almost endless hot water is here! 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.
Heat energy recovered by the ThermoDrain will increase threefold the capacity of a water heater rendering cold showers a thing of the past! Imagine turning your 40 or 60 gallon hot water tank into a 120 or 180 gallon tank for endless showers and pay up to 40%* less than your original hot water bill.
Instantaneous water heaters coupled up with ThermoDrain technology will result in both a higher flow rate. The result is an upgraded water heater with a lower operating cost.

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.
99.9% of energy efficient homes use the TD342B. The TD342B gives the optimum performance and savings versus investment. Most energy efficiency building standards recommend that a drain water heat recovery be at least 42% efficient. 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™ METRIC MODELS (new August 2015)
Note: We do offer the ThermoDrain in metric sizes. 75mm drain diameter x 22mm coil for countries that are currently using metric standard pipe sizes. The drain couplings supplied are also metric compatible.
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.
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.
