Factors to Consider When Choosing from Commercial Gas Water Heaters The most obvious difference between commercial gas water heaters and those for single family residences is their size and capacity. There are also other considerations to look for that affect the performance and durability of a gas water heater that don’t apply to electric water heaters. There are also a number of differences among the various brands and individual features available on the market. While some water heater sales companies carry only one or two brands of water heaters, others offer a variety so that you have more options to meet your specific needs. Before considering the size water heater that will be needed to heat the volume of water required, the first thing to consider is the brand. Some people believe that an American Standard water heater is the best choice while others think that A.O. Smith heaters outperform American water heaters. Although it often comes down to personal choice, there are a few brands that outrank the others in terms of selection and performance. These include: •

American Water

American Standar

Polaris

A.O. Smith

Shopping online for commercial water heaters offers a number of advantages over shopping in a physical store. In particular, information on each type is readily available and it is easier to compare the most important features to determine which type of heater is the right one for the job.


The amount of gas that is used each hour to operate the gas water heater is measured in BTUs. The higher the BTUs, the larger the volume of water that can be quickly heated. While a facility that has only minimal requirements for hot water to serve for personal and janitorial needs of employees, large living complexes that require hot water for multiple functions will require much larger volumes of water. This is also true of food preparation or handling facilities. In order to determine the right capacity and BTUs, each sink, shower, and any other area that requires hot water must be considered to determine what the hourly hot water use will be. For example, the sink in your restroom might require no more than 5 gallons per hour while the janitorial sink requires 15 gallons per hour. Once you have determined the hourly capacity that your facility requires, you can calculate the needed BTUs. Based on the fact that water has a weight of 8.34pounds/gallon and the 120° F standard temperature setting, with an assumed water efficiency of 75%, BTUs for a requirement of 75 gallons of hot water per hour can be calculated as follows: BTU Input = Water Volume (lb.) x Temperature rise (° F) x 1 BTU/lb.° F = required gallons of water per hour x Temperature Rise ° F x 8.34 lb./gal Thermal Efficiency

Or

75 GPH x 70° F x 8.34 lb.

= 58,380 BTU Input

.75 Choosing a water heater that will provide the needed water but does not heat well over the amount used will be the most energy-efficient choice. Those with a self-cleaning system will also add to lower energy use and lower costs. Additional factors to take into consideration when shopping for a commercial gas water heater is to consider the available space and the ease of installation offered by each.
