Aqua-Motion’s Aqua-Flash 2018 AHR Expo award-winning hot-water recirculation system offers instant comfortable 90° water at the sink and does not require power/batteries at sink, the company explains. The pump installs directly on the hot-water tank and a built-in timer runs the system only when hot water is needed. Other features include: rugged valve construction, stainless/bronze features, a large water passage to prevent calcium buildup, no screens to plug up and the system saves up to 12,000 gal. per year, AquaMotion adds. Models are available for tank, tankless and combi heaters.
