A series of successful installations has made construction manager Cliff Holden a big believer in tankless water heating systems for the school-building projects he oversees. Since 2007, the 15-unit Burlson (Texas) Independent School District (BISD) has erected six new educational facilities under Holden's direction. and the latest three have all featured multiple-unit, tankless solutions - in no small part because he wholeheartedly championed the idea.

The newest of these projects is also the largest and most complex: the 550,000-square-foot Centennial High School in Burleson, about 12 miles due south of Fort Worth. Centennial's hot-water delivery strategy features three multi-unit systems, encompassing a total of 25 tankless water heaters from Noritz America; These units feed food-service and culinary kitchens as well as locker=room sinks and showers in the main building; plus locker room facilities in the adjacent, standalone, indoor-practice field house.
