Domestic Hot Water Recirculation for Residential Applications

February 27: Residential Focus
Presented by John Barba, Dave Holdorf and Rick Mayo

The Department of Energy says the average family of four can waste up to 12,000 gallons of water every year just waiting for hot water to arrive at a plumbing fixture. A well-conceived domestic hot water recirculation system not only reduces that waste, but it also significantly speeds up delivery time.
But making sure you have the right DHW recirculation solution for your customers can be the difference between success and a system that doesn’t meet expectations. In this fast-paced, fact-filled presentation you’ll learn about the best possible solutions for new construction, retrofit applications, tank-type water heaters as well as tankless units.

Heat Pump water heater manufacturers are split on the topic, but saving water is just as important as saving electricity.

In this fast-paced, fact-filled hour, we’ll discuss the various DHW recirculation options and review which ones work best with Heat Pump water heaters and which ones should be avoided at all costs.
