On-demand hot water pumps save water and energy at the touch of a button

Many homes have a faucet or bathroom where it takes a long time for hot water to reach. That may be a kitchen sink or a bathroom. Many people turn the water on and wait for a several seconds for the water to get hot enough to use. Although it may take only 30 seconds or less each time, day in and day out that water adds up to a lot of waste.

That could add up to 8,000 to 12,000 gallons of water per year, per house. That could cost each homeowner $200 to $400 or more a year in water and energy costs, as well as sewage treatment costs.

That's why Larry Acker, CEO of ACT, Inc., developed the ACT, Inc. D'MAND Kontrols' instant hot water distribution system. It's an electronic pump that's installed into the home's plumbing system, usually near the farthest fixture or at the end of the dedicated return line.

The pump simply moves the hot water you already have through the plumbing system faster, without wasting hot water. The pump can turn on when you need it and turn off when the hot water reaches the fixture.

In Sierra Vista, Arizona, building codes encourage the use of hot water pump to reduce water use and energy loss. There is some discussion whether a full-time or timer-operated pump is better than an on-demand pump. However, local residents who have experienced the on-demand pump understand the benefits.

In a letter to the editor of the Sierra Vista Herald, one resident wrote regarding timer vs. on-demand pumps:

" ... [W]hen it comes to the huge heat (aka energy = dollars) losses due to constant recirculation of water, from a home owner's behavioral perspective, there are literally 1000s of surveys where homeowners say: "instant hot water" is hot water at my faucet within 2-4 seconds after turning on the faucet.

 
When it comes to hot water, one should ask themselves "When do I want hot water?" The answer is: just before I need it. That's what makes the on-demand pump so attractive - make a hot water demand just before you need it. The homeowner controls the event - the pump does the rest, automatically.

One final comment: the Cochise Water Project conducted a survey of homeowners who installed on-demand pumps with grant assistance from the project. 100 percent of respondents said they would do it again and 98 plus percent said they "almost never" forget to push the button to activate the pump when they want hot water."

Watch Larry Acker explain how an on-demand pump can help you stop wasting hot water.
