Recovery ratings based upon the supply of 200°F boiler water to a single heating coil to heat domestic potable water from 50-140°F. For 180°F boiler water reduce recovery ratings by 25%.

Recovery ratings based upon one heating coil installed in tank. For additional coils, use the continuous demand rating.
