Designed to respond to mid-range hot water demands, such as those of an average-sized bathroom, American Hometec’s Model AHQ-T16 tankless water heater is stylish in black with a brushed chrome frame and a blue LED smooth-touch temperature control panel. Compact at 17 3/4 in. x 12 5/8 in. x 21 1/16 in., it incorporates the company’s patented Coilless Technology, which heats water indirectly and eliminates limescale buildup on electrical components, thus preserving the unit’s energy efficiency.
