Search, review and select a model from ProLine, Effex, Voltex, Polaris, Voltex, and Vertex, powered by electricity, natural or propane gas, and built with the water tank or tankless.
The list of AO Smith hot water heaters for residential applications is very long, so homeowners have more flexibility and options to choose from; from the economy gas and electric models to the advanced models with superior features and quality, some equally good as found in the commercial line.
AO Smith manufacturer, as a leader in innovation and manufacturing energy-saving models, designs, builds, distributes and field supports an entire line of residential and commercial water heaters and boilers, offering many great features:
There are two main types of AO Smith water heaters for home use; tank-type with the capacities of up to 98 gallons and tankless for single or multiple fixture uses, both powered either by gas or electricity. All the models are grouped into three categories where the ProLine XE is, according to the manufacturer, the best to buy.
Residential gas water heaters from AO Smith come in much greater number than the electric, where the variety of models are available. Based on the venting options, gas models are found as the atmospheric, power vent, direct vent, and power direct vent.
Gas models are coming from the ProLine series, and are recommended to every homeowner, either looking for the economy models, models with the reduced gas emission, condensing with the ultra high efficiency or high recovery - for larger families.
AO Smith water heaters are also designed with the latest technology, state-of-the-art design, and long-lasting elements.
Vertex and Polaris, with the helical heat exchanger, condensing design, advanced gas and electronic control, heavy duty anodes and stainless steel tank, are two of the most innovative and efficient tank-type models from AO Smith - definitely recommended to those who are looking for more.
When it comes to savings, Vertex Power-Direct Vent model, as the high performing and Energy Star unit that also provides an endless supply of hot water, has the annual cost of operation around $200 (year - 2017).
More affordable while still coming from the best ProLine XE series is the power-direct vent model GPDX 50L. This 50-gal model has the highest First Hour Rating (118 gallons) and energy factor (0.73) of all non-condensing models with the 50-gal tank capacity. Or if you need a water heater that produces more hot water, buy GPDX 75L.
AO Smith water heaters are also designed with the tankless technology, which means water is heated on demand and distributed in endless supply, either for point-of-use or whole-house use. ProLine XE tankless are available as the condensing or non-condensing, where the high efficient models, with the recirculation pump and low gas emission, are the most advanced. The tankless heaters are smart, safe and small and can be installed either inside or outside (depends on the model).
A good example is the model ATO-540H-N, one of the top sellers and with the most positive user reviews. It comes with the commercial grade components and high energy factor and water flow making it ideal for homes with up to 4 baths.
This is a good buy.
Most of the AO Smith water heaters that use electricity are coming from the ProLine series, built for residential and mobile homes, as the standard or advanced models. One of the top water heaters is coming from the ProLine XE series, featuring the electronic display, diagnostic system, stainless steel heating elements, dry fire protection, multiple operating modes and
10-year warranty. This is what ensures maximum energy savings, great power output, faster recovery, and reliable operation.
Electric models can be found for special use also, as the Lowboy, Table Top or point-of-use for under sink installations and single use.
With an addition of the heat pump, AO Smith electric water heaters can now operate with ultra-high efficiency, two times more efficient than the conventional type.
This is what makes Voltex heat pumps Energy Star compliant that can save over 50%. These are also known as hybrids - the most advanced electric units that utilize the heat pump and long lasting heating elements with dry fire protection, electronic control panel for programming and troubleshooting. With several models available, Voltex, heat pumps from AO Smith, do a great job in supplying plenty of hot water - up to 5 showers operating at the same time.
Most of the tank-type water heaters from AO Smith come with the warranty of 6 years, either budget-friendly models or advanced such as Vertex, while some, such as Polaris or Voltex have a 10-year warranty.
Tankless have a longer warranty from all of the tank-type gas and electric models - 15 years.
