Which manufacturer builds the best gas water heater - AO Smith, Bradford White, Rheem or American? Explore the details and unique features of the best rated gas powered tank-type models.
The best gas water heaters utilize the condensing technology boosting the energy efficiency above 90%, much more than the conventional type, which is around 60%. Gas condensing water heaters will have higher initial cost but will reduce the energy consumption up to 30% providing substantial savings. Furthermore, condensing units heat water faster so the recovery time and first hour rating for the same tank size are better, when compares to the conventional type.
This is what you should be looking for when searching online for the best gas water heater - condensing technology. Condensing or near-condensing heaters are the ultra efficiency models, Energy Star qualified that are incentivised by the government through the tax breaks of up to 30%.

Vertex is a condensing tank type heater, recommended in many user reviews, plumbing forums and by the online expert reviewers such as consumersearch.com.
AO Smith Vertex is a high efficiency unit that has the energy factor of 0.96 EF, almost the same EF as the top tankless models, but it has lower installation costs than tankless while still providing lots of hot water.
Vertex GDHE-50 is the power direct vent unit that is offered with the capacity of 50 gallons for high demand homes. With the First Hour Rating of amazing 164 gallons per hour and water flow delivery of over 4 gallons per minute, Vertex provides more hot water than models with the larger tanks.
Superb features such as the powerful burner and durable heat exchanger that provides 100,000 BTUs, the advanced digital control panel and ability for remote monitoring, makes
AO Smith Vertex the best buy. Components such as the glass lining and two anode rods are commercial grade, heat exchanger with the helical design provides greater heat transfer while the burner is eco-friendly as it produces less NOx gases.
Polaris PG10 50-199-3NV from the American water heating company is the high efficiency gas water heater that offers over 95% thermal efficiency and incredible First Hour Recovery of 257 gallons per hour, much more than the above Vertex.
Polaris is not the best gas water heater due to its high efficiency only, but the quality elements. These are the high grade 444 stainless steel tank and metal fiber burner that produces very clean and low NOx flame. The flue is also made of the stainless steel and has a specific spiral design that, with the submerged combustion chamber, significantly reduces the energy loss and ensures dependable and very effective heating. Stainless steel construction and its high resistance to corrosion, eliminates the need for anode rod also.
Polaris PG10 50-199-3NV comes with the 50-gallon tank size and due to its powerful 199,000 BTU burner is recommended not only for domestic water heating, but home heating (radiant hydronic heating and forced air hydronic heat).
Such high quality materials allow Polaris to provide 10-year warranty. Other superb elements include Self-Diagnostic Control System that indicates the operating status and makes the troubleshooting easy, hot surface ignitor and ultra quiet radial blower.
Westinghouse WGR050NG076 is the 50 gallons water heater that comes with the 97% energy efficiency - another great unit but cheaper than the above Polaris; it costs around $2500, which is almost as Vertex. It also has a 10-year warranty, but lower First Hour Rating than both models - 133 GPH.
The main features include the stainless steel tank, ultra-low NOx gas burner and LCD display with the Eco mode for savings and environment friendly usage.
High efficiency, as found on the above products, is achieved through the specific water heater design; insulation is thicker, unique flue system, heat traps are added, pilot light used for the ignition is replaced with the electronic ignition system and burners are more efficient.
The best gas water heater has all the above features plus premium quality of the material used and workmanship. The best rated gas models are either Power Vent (PV) or Direct Vent (DV) which maximizes the combustion, increases the efficiency and safety.
Warranty is longer, 10 - 12 years. Some gas water heaters have the stainless steel tank which does not require anodes, while others have bigger anode rods or powered non-sacrificial anodes, and quality porcelain tank lining... for durability. The stainless steel tank are corrosion free, do not leak, so the warranty can be found as the limited lifetime.
Sediments and lime buildup are reduced to a minimum by adding the self-cleaning systems and dip tubes with the turbulent water flow.
