AMP Water Heaters are condensing, high-efficiency, gas-fired appliances designed for use in direct domestic hot water
heating systems where supply water temperature does not exceed 190°F. These water heaters have special coil type
stainless steel heat exchangers, constructed, tested and stamped per Section IV of the ASME Boiler and Pressure Vessel
Code, which provide maximum heat transfer and simultaneous protection against flue gas product corrosion. These
water heaters are
not
designed for use in space heating systems or swimming pool heating systems.
