 On-demand hot water pump cuts water and energy waste in high performance home

Hot water pump in the Proud Green Home of St. Louis

With record droughts in some parts of the country, water conservation now receives as much focus as energy savings.

That's why the Proud Green Home of Cincinnati will incorporate some proven water-saving technology to reduce its environmental impact.

Architect and homeowner Ben Jacks has designed the water heating system to include an on-demand recirculation pump from Advanced Conservation Technology (ACT), Inc. D'MAND®.

The ACT, Inc. D’MAND Kontrol® hot water distribution system works by circulating ambient temperature water that normally goes down the drain back to the water heater through the cold water line. At the same time, it fills the hot water line with hot water from the water heater. Simply hit the button next to the D’MAND Kontrol® hot water distribution system, activate the motion sensor, or use the remote transmitter to activate it from anywhere in your home, to provide users with instant hot water.

Since no water runs down the drain while you wait for hot water, users save significant amounts of water every time they do the dishes, wash their hands, take a shower, or run a bath. Due to the energy and water conservation methods of the D’MAND Kontrol® System, a customer can realize a payback on the system in just a few years, not to mention the beneficial impact it will have in conserving the earth’s most precious commodities.

At the 2014 Energy & Environmental Building Alliance Conference and Expo, Larry Acker, CEO of Advanced Conservation Technology (ACT), Inc. D'MAND ®, explains the benefits of demand control pumps for homeowners and our environment.

According to Acker, 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

Since no water runs down the drain while you wait for hot water, you will now save significant amounts of water every time you do the dishes, wash your hands, take a shower, or run a bath. Due to the energy and water conservation methods of the D’MAND Kontrol® System, a customer can realize a payback on the system in just a few years, not to mention the beneficial impact it will have in conserving the earth’s most precious commodities.

The Proud Green Home of Cincinnati is a high performance demonstration home with a goal of achieving some of the toughest green building certifications available.

The home on the east side of Cincinnati was designed by its owner, Ben Jacks, an architect and an associate professor at Miami University, Oxford, Ohio, to be a near net-zero energy home and achieve LEED for Homes Platinum and Passive House certification.

Jacks, a licensed architect, holds a Masters of Architecture from the University of Pennsylvania and holds additional degrees from the University of Chicago and the University of Southern Maine. He has worked on more than 35 commercial, residential, public sector and historic preservation projects.

Green Building Consulting, a Cincinnati-based green building consulting and rating firm, will conduct the testing and certification for the various programs.

The house is an aspiring LEED Platinum Passive House, consisting of 4,992 gross square feet on four floors. The home is being built in the hilly Mount Lookout neighborhood overlooking the Little Miami River valley. It's designed to be a flexibly family structure with an eye toward aging in place.

Jacks plans to build the home using insulated concrete form construction, heat pump water heater, ductless mini split HVAC and an energy recovery ventilator, and an on-demand hot water recirculation pump.

Construction will start in the summer of 2015 and ProudGreenHome.com will provide ongoing media coverage of the project in the Proud Green Home of Cincinnati Research Center
