The Power Pipe                                 

Save money, save energy & reduce greenhouse gas emissions

Technically known as a falling film heat exchanger, the Power-Pipe is based on a fundamental physical principal called the falling film effect.  Water falling down a vertical drain stack does not run down the middle of the stack, but instead clings to its inside wall. This creates a thin "falling film" from which the all-copper nergy.

The Power-Pipe System is superior to other falling film heat exchangers as well as to other types of heat exchangers because of its patent-pending design consists of multiple coils of copper tube, wrapped together around a central copper drainpipe.


Copper is used because of its efficiency as a heat conductor. As a result, the Power-Pipe has a high heat transfer rate on a surface area basis.

A typical 60-inch Power-Pipe can raise the tempeature of incoming cold water from 10°C (50°F) to as much as 24°C (75°F), under equal flow conditions. When this water is then directed to the water heating system for further heating, that system is not required to use as much energy as it would without a Power-Pipe installed.

By installing a Power-Pipe, homeowners can expect to save up to 40% on their overall water heating costs. Industrial customers and commercial enterprises can save up to 70%.

The Power-Pipe's performance has been verified by Natural Resources Canada, the University of Waterloo, as well as other American and Canadian agencies and power companies, in independent third-party testing. In diverse applications, the Power-Pipe is a proven way to save energy and money and to reduce greenhouse gas emissions throughout the long service life of the system.

Power-Pipe DWHR Systems are manufactured using quality materials, yet, the initial investment in a Power-Pipe System is modest. Because of this advantage and because of the important savings on energy costs the system generates, institutions can expect an excellent return on investment.

Power-Pipe Systems are simple to specify and easy to install. In addition, they are backed by full technical support. This free support includes energy savings studies, feasibility analyses, system design consultations, CAD drawing elements, and installation support.
