High Quality longer-life residential water heaters. Made by the pioneer water heater manufacturer having the best quality glass-lined tanks.
Commercial grade Incoloy sheathed elements with Ni-Chrome resistance wire embedded in magnesium oxide. Range 1.5 to 4.5 kW, rated 230 Volt, suitable for 220-240 Volt power supply.
Surface-mounted control thermostats with a temperature range from 43°C/110°F to maximum 71°C/160°F and hi-limit factory fixed setting at 83°C/180°F.
Magnesium anode rods have a stainless-steel core that extends the life of the anode rod allowing superior tank protection far longer than standard anode rods.
Heavy-duty carbon steel fused with A.O Smith glass lining avoiding corrosion & increased life.
Maximum working pressure is rated at 150psi/10bar. Test pressure per UL 174 std is 300psi/20bar.
Factory-installed, side-mounted, CSA/ASME certified T&P safety relief valve is standard on all models.
Code compliance meets the Federal Energy Efficiency Standards according to the 2004 edition of the National Appliance Energy Conservation Act (NAECA) of 1992 and the standby loss requirements of the U.S. Department of Energy and Current Edition of ASHRAE/IES 90.1.
Residential export water heaters comply with UL 174, GSO, PAI, and IEC 60335-2-21.
Proven U. S. designed strong steel tank with the A. O. Smith manufactured special cobalt enhanced glass coating fused to the steel ensuring long lifetime and resistance to scaling build-up.
Factory-installed brackets for wall-mounted installation.
Thick injected CFC free foam insulation 22mm thick along the sides, 40mm on top of the heater, minimizing heat losses.
The tanks are tested at 16 bar hydrostatic pressure to meet strict CE standards. This results in a rated working pressure of 8 bar.
An electric commercial-grade Incoloy heating element with a low watt density, making it very suitable for usage in hard water areas.
A manual high-temperature safety thermostat cuts of power supply to the heating element in case of overheating.
A large magnesium replaceable anode.
Stainless steel hot water outlet pipe and cold-water inlet with the diffuser.
Dial type thermometer & Pilot light indicating operation of the heating element are provided on the heater body.
The water heater is suitable for operation on a 220 to 240 Volt single-phase power supply.
Code compliance: CE, IEC 60335, SASO, 930.
A. O. Smith’s new propriety advanced electronic water heater control provides precise + or – 1ºF temperature control, which is ideal for industrial and food service applications where accurate hot water temperatures are needed.
Animated icons display detailed operational and diagnostic information. Fault or alert messages appear if an operational issue occurs.
Low water cut-off uses a remote electronic immersion type probe to prevent energizing of the elements in the event of low water condition and eliminates accidental dry firing.
Progressive modulating matches the number of elements to current load conditions. Rotates and lead-lag element loads to provide long life and equal wear.
The seven-day clock may be programmed for the night set back and or weekend shutdown to reduce operating cost and save money.
Modbus/BACnet is compatible with the optional Gateway interface.
Standard Permaglas glass lining.
All models are constructed to the requirements of ASME and are available in 125, 150, and 160 psi working pressures (125 psi working pressure – standard).
Heavy-duty elements have Incoloy sheathing: provide excellent protection against oxidation and scaling. The input ranges from 15kW to 900kW.
Control and power circuit fusing to meet N.E.C.
Meets the standby loss requirements of the U.S. Department of Energy, NRCan, and the current edition of ASHRAE/IES 90.1.
