What makes this product green?
- Energy-conserving equipment
The Power-Pipe installs in a vertical plumbing drain stack, recovering heat energy from draining water to warm an incoming cold water supply. As liquid drains, it clings to the inner surface of the copper pipe due to surface tension; part of the draining water's thermal energy is transferred to incoming water line (squared copper for maximum contact area) coiled around the stack. The heat transfer is most effective with equal drain and incoming flow volumes. Multiple units may be used in parallel for large flows. The energy savings potential can be significant, particularly in commercial or institutional applications with showers, laundry, dishwashing, boiler blowdown, etc. The Power-Pipe can also be effective in residential applications, and is approved for potable water.
