Drain Water Heat Recovery

---

Drain Water Heat Recovery (DWHR) is a simple concept. Consider the heat energy that's going down the drain when you shower. Using a Power-Pipe®, the heat from this outgoing warm drain water can be harnessed and used to preheat incoming cold fresh water, reducing your hot water heating costs.

Nearly 1/4 of the energy consumed in a typical home is used to heat water for everyday household tasks. Nearly 90% of that energy runs down the drain, mostly in your shower. Now you can recover and re-use much of that energy before it is lost, with a Power-Pipe^® Drain Water Heat Recovery (DWHR) System. With the Power-Pipe^® installed on your home shower, you can:

• Reduce your overall household water heating costs by up to 35%
• Increase your hot water capacity
• Protect the environment by reducing greenhouse gas emissions

The Power-Pipe^® DWHR System is simple, effective, and maintenance-free, because it is based on a fundamental physical principle called the "falling film" effect. Water falling down a vertical pipe does not run down the center of that pipe as it would seem, but instead clings to its inside wall (think what happens when pouring from a teapot). This creates a thin "falling film" from which the Power-Pipe^® can readily recover heat energy.

Power-Pipe^® Details:

• Consists of multiple coils of copper tube wrapped together around a copper central drain pipe
• Hot water going down the drain transfers its heat to incoming cold water moving up the coils
• The exclusive, patent-pending design provides greater and more efficient heat exchange than other DWHR devices, with no discernible water pressure loss
