Ruud Gas Water Heaters 
Review and Buying Tips

A review of Ruud gas water heaters using the tankless and storage tank-type design, including high efficiency, condensing, low NOx, direct, atmospheric and power vented models. Explore the main features, pros, and cons.

Features and benefits

All the Ruud gas water heaters reviewed here are designed for the whole-house hot water supply in residential and light commercial applications, either small or large in size.

Most of the gas water heaters are using the conventional technology for water heating which allows Ruud to provide energy efficiency of an average 0.82 on non-condensing tankless models and 0.67 for storage tank-type. There are also condensing water heaters found in both tank-type and tankless category, and this technology allows much higher energy factors of over 0.9.

Other advanced features found in some Ruud gas-powered models are:

  • EverKleen Self Cleaning System reduces the risk of the sediment and limescale buildup at the bottom of the tank and other elements. Cold water enters the tank through the specially designed dip tube, which creates a turbulent flow reducing the risk of deposits while increasing the efficiency.
  • Guardian System that uses the air-fuel shut off device and flame arrestor plate to protect the unit in the presence of flammable vapor accumulation also reduces the time for maintenance by eliminating the need for the filters.
  • The porcelain enamel tank lining against corrosion and for durability.
  • Low NOx gas burner with low nitrous oxide emission that meets 40ng/J NOx requirements making the gas burner eco-friendly.

Standard warranty length is 6 years, but there are models where the extended warranty is available for up to 10 years.
