The Reliance manufacturer offers many types and models for gas potable water heating in residential applications including standard, ultra-efficient, ultra-low NOx, high efficiency, mobile home and tankless.
Some of the Reliance gas water heaters are designed as economy models (priced several hundred dollars), and some are built for high-demanding homes and customers who are looking for the most advanced technology followed by greater savings.
This review will present the best water heaters from this manufacturer, with the main features and benefits.
The best water heaters from Reliance usually have a high energy factor, which is 0.67 for energy-efficient conventional type and higher for condensing. High-efficiency models are found among power vented, power direct vented, and atmospheric vented models, allowing buyers great selection.
Reliance gas water heaters with ultra-high efficiency are found as the power and power direct vented models, both models Energy Star compliant.
These water heaters are equipped with advanced electronics that regulate the water temperature inside the tank and the heating operation in general. Another great benefit is the environment-friendly and powerful gas burner that efficiently burns the natural or propane gas with ultra-low NOx emission.
The Reliance Power direct vent group has two models from the EnviroSense series, both with the 50-gallon tank; 6-50-YTPDT run by natural gas, and 6-50-HTPDT powered by propane. The group has the highest energy efficiency of all Reliance gas water heaters, 96%, and a high recovery of 164 gallons, resulting in very low energy loss and great comfort.
The power vented model, 6-50-YTVIT, has similar features, but the slightly lower efficiency of 90%, still extremely high when compared to most models on the market. It is not equipped with the LCD display as the power direct vent model.
Except for the higher price, the main disadvantage is the short 6-year warranty, for both types.
The next group of recommended water heaters comes from the conventional type that uses the power vented system and an environmentally-friendly gas burner for low NOx emissions.
Reliance power vented water heaters are recommended for homes that do not have a chimney built and where greater flexibility in vent pipe routing and length is needed.
Several models are found in power vented groups, and these come with the most popular tank sizes of 40-gal (6-40-YRVIT), 50-gal (6-50-YRVIT), and 75-gal (6-75-YRVHTL).
Power vent water heaters are built as high-recovery models delivering more hot water for the period of the peak demand and supplying a sufficient amount of hot water for family sizes from 3 to more than 5 family members.
The main disadvantages are the short warranty and the absence of the self-cleaning system, making the unit prone to sediment buildup.
From the Reliance atmospheric vent water heaters, one group of high-efficiency units utilizes the patented air intake system. This feature allows the pressurized environment within the combustion chamber to make the air/gas mixture ideal.
With the great air and gas mix, the efficiency increases while boosting the performance for more energy savings. These are the most advanced atmospheric type water heaters from Reliance and units with the longest warranty, 12 years, mainly thanks to the powered anode and self-cleaning system.
There are two sizes, 40-gal (12-40-GPCT) and 50-gallon (12-50-GPCT), both equipped with advanced electronics and LCD display, which provides user-friendly and easy-to-use controls for easy temperature adjustment and service diagnostics.
Unlike other conventional heaters, this type comes with a powered anode rod that protects the metal storage tank without sacrificing itself.
Most of the Reliance gas water heaters use the old fashion pilot light, while the best gas models utilize the electronic ignition, known as hot surface ignition, which is more reliable and does not waste energy.
The water heater burns propane and natural gas with the low NOx emission thanks to the Green Choice gas burner that significantly reduces environmental pollution (some estimations show a reduction of 33%).
The factory built-in powered anode rod provides a longer heater’s life, and since it does not deplete over time, it eliminates the need for services.
The Reliance Sta-Kleen system utilizes the specially designed dip tube that reduces the lime and sediment buildup inside the tank.
Another popular group of gas water heaters comes from the tankless series, a series with on-demand water heating and a continuous supply of hot water.
