"Easy as 1-2-3" Tankless Selection for Homeowners
Our “easy as 1-2-3” tankless selection concept is a good starting point for homeowners. The chart below shows which tankless models are typically selected based on the number of bathrooms in a home. For example, if your home has 1 bathroom, a Rheem tankless RTG2-42 series water heater should provide an ample supply of continuous hot water.  If your home has 1-2 bathrooms, you should consider a Rheem RTG-53 series water heater. For up to 3 bathroom homes, the larger RTG-74 series tankless water heater should be selected. 
For homes with more than 3 bathrooms, large volume demands for hot water, or hot water circulating systems, you should contact a Rheem tankless professional for help in determining a tankless water heating system that’s right for you.

Best Fit Selection by a Tankless Professional
A tankless professional generally uses a combination of tankless technical data and other factors to determine the best fit for their customers. These factors include incoming cold-water temperature, size of gas supply line, and the amount of hot water required during "peak" demand times which vary from home to home. A combination of all these factors is necessary to determine an accurate tankless selection. With this in mind, Rheem highly recommends professional assistance in the selection and installation whenever possible. Need professional assistance?
