Precision Engineering Leads to High Performance

At Ecodrain, we’re on a mission to build the best possible drain water heat recovery systems. We’ve built hundreds of prototypes and conducted thousands of experiments. We've fine-tuned every aspect of the design, all with the aim of maximizing the performance, minimizing the pressure loss, and meeting the highest safety and quality standards. The key to saving you money is a second generation, all copper, insert into the cold water heat transfer tubes called a turbulator which boosts the rate at which the cold water absorbs heat. The heat transfer tubes are precision formed using specialized aerospace tooling to maximize contact with the inner drain line. The tubes are connected at each end with a custom designed manifold made from an advanced grade of lead free brass that is 96% copper, and brazes and solders as readily as standard copper tubing and fittings. The one-piece manifold ensures high quality brazing and leak free joints with a long life.

Installation Scenarios:

Depending on the layout of the home or building, and the number of drain stacks in the home, there are different ways in which the ecodrain VT1000 can be connected to the piping system. For more information about the different installation scenarios, please download our installation guide here

Ecodrain V1000 equal flow installation

The above scenario shows the ecodrain VT1000 connected such that the preheated outlet leads to the water heater and the cold side of the shower mixing valve. This scenario is called equal flow since the flow rate of drain water is equal to the flow rate of cold water being preheated during the shower. This scenario will result in the maximum energy savings and is the scenario under which the CSA B55.1 tests are conducted. When this scenario is not possible or not desirable due to installation issues, other scenarios are available such as preheating to the water heater only or the shower mixing valve only. More information is available in our installation guide. 

Easy To Install:

Ecodrain VT1000 heat exchangers are easy to install. Each unit is shipped with two flexible couplings designed to connect the heat exchanger copper drain line to plastic drain piping. The cold water connections are 3/4" female solder fittings and can be soldered directly to 3/4" copper tubing without any additional connectors. When connecting to PEX, PEX fittings can be soldered to the cold water connections on the ecodrain. For more information, watch our installation video below or download our installation guide here
