Recirculation pumps deliver hot water on demand

One of the most common residential plumbing system problems is the wait for hot water.

Regardless of whether a home has a tank or tankless water heater, the water in the lines between the water heater and the fixture loses heat. Depending on how long those lines are, it may take many seconds for hot water to run through the pipes to reach the fixtures.

All that water goes down the drain, including the energy used to move it, treat it and heat it, as well as the energy used to process it as sewage.

Hot water recirculation pumps reduce the wait for hot water to next to nothing. That's why home builders in drought-stricken states are turning to recirculation pumps to help meet strict new standards.

At the 2015 Greenbuild Expo, Larry Acker, CEO of Advanced Conservation Technology (ACT), Inc. D'MAND®,  talked about his company's product that save water and energy, and deliver hot water right when you want it.

Acker said people use the ACT, Inc. D'MAND Kontrols® instant hot water distribution system in their homes because:

  • Saves 8,000 - 12,000 gallons of water per year
  • Eliminates 8,000 - 12,000 gallons of sewage usage per year
  • Saves $200 - $400 (or more) in water and energy costs per year
  • Eliminates 3,000 pounds of carbon dioxide emissions per year
  • Costs less than $1 in electricity per year
