70+ Gallon Tank Water Heaters

Extra-large heaters of this size begin to edge into the commercial market. The prices also look more suitable for businesses than for individuals.

Rheem makes a 70- and 75-gallon natural gas model, while American Water Heaters weighs in with a 70-gallon model that has spark-ignition and looks like it belongs in a sci-fi movie. It is billed as a heater for commercial applications.

Rheem also has an 85-gallon electric monster, appropriate called the “Marathon” model. The polybutene tank cannot rust or corrode.

There are several entries in the 80-gallon market, with Stiebel Eltron, Whirlpool, G.E., Reliance, A.O. Smith, Rheem and Bradford White offering choices, many of them electric.

There is a wide variance in price for these options, from under $800 to $2,000+. The Stiebel Eltron brand is ranked the most energy-efficient of the electric bunch, while Rheem has a high-ranking gas model.
Both can save you thousands of dollars over several years time.
