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.
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.
There is only one model from XR90 series and it has a capacity of 29 gallons, but with the First Hour Rating of 90 gallons and Recovery Rate of 61 GPH, it outperforms the standard 50-gal unit. The XR90 is the small and lightweight unit and when compared to the 50-gal unit, it provides more flexibility during the installation as it has a smaller footprint.
Gas water heaters from the Professional series are designed in a range from 29 to 50 gallons and are available as short and tall in height. All the models with the Powered Damper have a high EF, which is from 0.67-0.69 while all other models have the energy factor of 0.62. They all come with the Low NOx gas burner, self-diagnostic system, and Guardian system, 8- or 12-year warranty and sizes from the lowest 38 to high 98 gallons:
Professional Ultra Low NOx Powered Damper Series - two models in the offer and both Energy Star approved. They come with the environment-friendly and Ultra Low NOx burner.
