Savings
Payback depends upon many factors. For example, if the Drainwater Heat Recovery System does the job of a new, or secondary water heater or permits the installation of a smaller water heater, the payback could be between a day and one year! The simplest way to determine the monetary-payback is to estimate your family's shower-usage and accept additional savings as a bonus. Since this also varies wildly, depending upon climate, geographical location, type and number of showerheads, the following guide was prepared based upon a single, low-flow showerhead: |
