Acorn Engineering has introduced the Meridian Hand Washing System, designed to use its Chronomite Instant Temp Tankless Water Heater. Working simultaneously with Acorn's Meridian Systems, Chronomite's water heater may be used with Meridian single- or multiple-station configurations. Due its compact dimensions, Instant Temp can be concealed under or behind the trap cover of the Meridian units. And, the Meridian/Chronomite washbasin is designed to conserve water. Acorn Engineering.
