American Polaris Water Heaters Review and What to Look for

Find out how American Polaris water heaters innovative design brings the highest energy efficiency and fantastic performance to in-home water heating. See the detailed review of Polaris advanced features and benefits you can expect.

Polaris hot water heaters are high-efficient and condensing tank-type heaters designed in two sizes of 34 and 50 gallons that offer superior recovery rate and first-hour rating. Both sizes are used for residential and commercial water heating and provide sufficient amount of hot water to high demanding applications.

Also, Polaris can be used for space heating, small and large homes, and it works perfectly with radiant hydronic heating systems and forced-air systems.

Ultra-high efficiency

One of the most significant advantages of the American Polaris water heaters is the high thermal efficiency of over 96%, ensuring excellent performance and lots of hot water. It is design-certified by CSA as a Category IV and direct-vented water heater, so it takes the fresh combustion air from the outside and transfers the flue gases out, keeping the inside air untouched.

Advanced design

An innovative design and collection of advanced features are what make Polaris unique. The tank is made of high-grade stainless steel, making the unit resistant to corrosion and rotten egg odor, as the anode rod is not used.

The flue tube inside the tank and surrounded by water is made of stainless steel also, but its unique spiral design brings much better results. It takes longer for the flue gases to escape the heater, so the heat transfer and efficiency increase.

The woven fiber premix burner uses either propane or natural gas. While it produces clean combustion with the bright blue flame, there is less NOx gases than many conventional-type heaters.

Thanks to its excellent performance and evenly distributed flame, a gas burner provides a fantastic heat transfer. The maximum power of 199,000 BTU is found on a 50-gallon model, and even with the high temperature it produces, Polaris water heaters have excellent resistance to thermal stress.

Power and flow rate

Both 34-gal and 50-gal models have capacities to heat not only potable water but provide enough heat for space heating. With two sizes and seven models available, you can choose a Polaris water heater with power ranging from 100,000 BTU to 199,000 BTU, first hour delivery from 170 gallons, and recovery rate from 129 to 253 GPH.


Sealed combustion makes these heaters safe for users as all the exhaust air is moved out through the power/direct venting while the fresh air for combustion is always provided. Polaris models use flexible venting systems. They can directly vent up to 120 feet using affordable PVC, ABS, and CPC pipes, horizontally through the wall or vertically through the roof, and using the concentric or two-pipe system.

Self-diagnostic system

These gas water heaters utilize three external LED indicators as part of the self-diagnostic control system for easier troubleshooting. All the information about the heater's operation/status and possible problems are stored in the microprocessor, which monitors nine critical functions.

Other important features to mention are the hot surface ignitor, which, when energized, glows red hot and automatically lights the gas.

Another great feature is a brushless radial blower that ensures quiet operation.

According to the American water heaters company, Polaris models are recommended for average and large-sized homes and are operating with an annual cost of around $220 and providing a UEF rating of 96%.

Due to its condensing design and high performance, they offer an endless shower time, supplying plenty of hot water to up to 3 showers operating simultaneously.

The company offers a 10-year warranty on the tank and one year on other parts.
