AO Smith 40 Gallon Water Heater Pro Max

For most homeowners the type of 40 gallon water heater they have installed is very important as it can contribute greatly to the energy bill. Some of the most widely available and popular units are the AO Smith 40 Gallon Water Heater Pro Max series.

To choose the right one for your requirements you have to consider a number of different factors such as the number of gallons required, the size of your family, the efficiency, type of power, and standard or direct vent.

All AO Smith 40 gallon water heaters in the Pro Max line come with various unique features. For example they have a technology known as Flammable Vapor Ignition Resistance which keeps all the vapors within the combustion chamber and also uses a special flame arrestor that prevents any flames from escaping the unit.

They also incorporate a system known as DynaClean. This protects the full water heating system from sediment and lime-scale build up; in turn this produces a more energy efficient unit which can maximize the output of hot water. The Pro Max series also has two in built systems that are called CoreGuard and PermaGlass that protect the inside of the tank from rust and corrosion using a special coating made from glass and stainless steel.

There are many different Pro Max models to choose from. There are units such as the ProMax Ultra Low NOx that causes little damage to the environment. If you have a big family requiring a lot of hot water in a short amount of time then there is the ProMax Plus High Recovery that offers up to 150 gallons of hot water in the first hour. Another option is the ProMax plus High Efficiency unit that is one of the most economical on the market; it includes an eco-friendly Green Choice gas burner.

Other AO Smith 40 gallon Pro Max water heaters include the Power Vent, Direct Vent, and SL models.
