"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 1-2 bathrooms, you should consider a Rheem RTG-64 series water heater. For up to 3 bathroom homes, the larger RTG-84 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.
