Once considered an obscure technology, hot-water recirculation systems are becoming a default spec in some drought-prone regions, John Vastyan reports in Plumbing & Mechanical magazine. As consumers, construction pros, and code officials look at water efficiency with a new sense of urgency, there’s a growing awareness of these systems that promise to save an estimated 12,000 to 15,000 gallons of water a year for a family of four.
Vastyan speaks with Keefer Rader, owner of Outlaw Mechanical in Albuquerque, New Mexico, who says that one the most common requests he receives is installation of domestic hot-water recirculation. “Recirc systems are code in our state for new construction, but people also realize that — because we’re in the desert — any form of water conservation is a good thing,” Rader tells Vastyan, adding that his company installs about 100 recirc systems each year. “Home and business owners don’t want to wait for the arrival of hot water because they know it’s not only scarce, but it’s also expensive to buy and to send down the drain,” he adds.
While homeowners say they want hot water at the tap in five seconds or less, many homeowners are stuck waiting a minute or two, and sometimes much longer, for their shower to heat up. Recirculation systems are one way to address that challenge and help your projects protect one of the planet’s most precious resources.
