ANSI Approved: November 2021

ASSE 1082-2021 is for water heaters with defined setpoint controls under various steady state flow conditions. These water heaters control the outlet temperature to specific limits and are installed within a hot water distribution system, but not at point-of-use. The water heater shall consist of a heat exchanger, a cold water inlet connection, a hot water outlet connection, and a means for precisely governing the outlet temperature. The device controller shall be listed to the appropriate electrical safety standard in accordance with the device category.

A hard copy version of this standard is also available.
