Students Get Into Hot Water At School

Electric tankless water heaters pass the test in Indiana school restrooms.

An electric tankless water heater in a school's boys' restroom also accommodates the hot water needs of the girls' restroom on the other side of the wall.

When Indiana Math and Science Academy, Indianapolis, was renovating a school building, its goals were to save costs on maintenance, operations, and installation. Facility management sought a water-heating system that could conserve water and be maintenance free. A problem, though, was that the new restrooms were located far from the mechanical room. The solution was to use one electric tankless water heater to handle all of the hot water needed for two restrooms.

The water heater, set at 8.5 W, was placed under the sink in the boys' restroom. The unit also serves the girls' restroom on the other side of the wall. This placement, with a short piping run, conserves water. Only one cold-water-system pipe is needed to run the unit. The coilless water-heating technology eliminates the need for periodic maintenance calls, regardless of water quality, according to the manufacturer. John Ayetekin, the schoolmaster and general manager of the academy, said the unit should reduce or eliminate maintenance costs.

The school used a point-of-use electric tankless hot water heater with coilless technology made by American Hometec, Wilmington, DE. Another AHM-C10 heater, set at 4.3 W, was installed under a sink in a health room.
