Tips on How to Choose the Best AO Smith Water Heater
Majority of the best AO Smith water heaters are exclusively designed with these features:
DynaClean system – This self-cleaning system reduces the sediment build-up while increasing the performance of the heater. DynaClean system is also the standard feature for Promax models.
Green-Choice gas burners are environment-friendly burners that are designed to reduce nitrogen dioxide emission.
CoreGuard anode rod is the aluminum and magnesium rod with a stainless steel core for protecting the tank from any aggressive water action. This feature is used on both Promax and Conservationist series.
Blue-Diamond glass coating – Used to protect the inner surface of the water tank from corrosion.
Flame arrestor – Made from the fireproof material, Cordierite, which distributes air evenly to gas burner keeping the flame inside the combustion chamber.
Permaglas coating – This is a long-lasting and efficient corrosion protection in the water heating industry.
AO Smith water heater machines are specifically designed to heat potable water in various residential applications using all 3 popular fuel sources: solar, electric and gas while utilizing advanced and conventional tankless, tank and hybrid technology.
Hybrid Models
Hybrid technology is the latest technology usually used in AO Smith water heater machines. The technology utilizes both gas and electric heating. NEXT-hybrid gas water heater uses both tank-type and tankless technologies, to ensure maximum transfer of heat for superior performance and high efficient hot water heating. Condensing design allows the NEXT-hybrid heater high 189 gallons cheaper PVC venting and first-hour delivery.
Voltex, the electric heat pump of AO Smith water heater machines is the only electrical unit which is Energy Star approved. Advertised as the green heater, it comes with the heat pump technology and environment-friendly refrigerant that reduces operating costs.
The 60 and 80-gallon models are the two AO Smith water heater machines utilizing this technology. Additionally, they are both high efficient and eligible for tax credits.
Condensing Models
Power direct vent and VERTEX power vent are the top AO Smith gas water heaters. Both models have 50-gallon capacity; however, they have different delivery and thermal efficiency. AO Smith Vertex models have a maximum gas input of approximately 76,000 and 100,000 Btu, to deliver a lot of hot water (127 and 164 gallons) for high demanding homes.
Vertex heaters are also equipped with more advanced features like heavy-duty anode rods for low nitrogen dioxide, better rust protection, high efficient gas burner and sophisticated diagnostic tool.
High Efficient Models
EFFEX is a high efficient AO Smith gas water heater that uses the patented and exclusive pressurized heating chamber for effective heating. Effex water heaters are available in 2 sizes, 40 and 50 gallons that offer high energy factor.
EFFEX models are very sophisticated compared to conventional tank-type heaters because they use the powered anode rod and electronic ignition for better tank protection.
