Instant hot water recirculation pumps from Laing Thermotech Inc. do more than offer consumers the benefit of having instant hot water in their home. They also conserve considerable energy and wasted water—which translates into substantial cost savings, according to independent research by consulting mechanical engineers Edward Saltzberg and Associates.
"Although Laing's products are best known as a convenience item to the average consumer, our ultra-efficient, low-energy-consumption pumps actually pay for themselves by reducing the homeowners' energy consumption and wasted water," said Scott S. Shimer, Laing's CEO.
Laing's Instant Hot Water Autocirc® Recirculation System, for example, costs less than 10 cents a day to run and can conserve enough energy to pay for itself in less than two years, Shimer says. Homeowners can save thousands of gallons of water each year, plus use less energy by not having to heat wasted water. By sending less water down the drain, they can also reap sewer savings.
According to independent study, consumers can save nearly $300 a year using the Autocirc System with an electric water heater. This is based on the water heater being set at an average temperature of 140º F, an incoming water temperature of 40º F, and running the pump four minutes per hour for 16 hours a day and 350 days a year. It is also based on electricity at $0.125 per kilowatt hour, water cost at $2.02/100 Ft³, and a sewer surcharge at $1.35/100 Ft³.
In addition to offering the Autocirc System for retrofit applications, Laing also sells a instant hot water recirculation product for new construction: the UltraCirc®. Both of these user-friendly systems give homeowners the advantage of having hot water almost instantly at every faucet and shower in their home. They:
-
Install easily with the existing hot water supply line
-
Require less energy to operate than similar products
-
Contain a quiet pump that is almost inaudible when running
-
Feature a low-flow design that helps to avoid pipe erosion problems
-
Can be installed by a plumber or homeowner
-
Are available from local plumbers and most home improvement stores
Laing is an industry pioneer that created the first practical do-it-yourself instant hot water circulation system. The company offers a variety of low-energy-consumption, fractional-horsepower pumps for residential, solar and industrial use.
