Find the Right Model For You

"Easy as 1-2-3" Tankless Selection

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 water heater should be selected. For homes with more than 3 bathrooms, large volume demands for hot water, or hot water circulating systems, two or more like models can be linked together with the EZ-Link cable or in a manifold configuration. For commercial applications, the GT-199 heavy-duty tankless water heater should be selected. The GT-199 can also be linked together in a manifold configuration to meet the higher volume demands for continuous hot water. In fact, up to 20 heavy-duty models can be linked together to work as one water heating system where only one remote control and manifold controller are required a Rheem exclusive.

Typical shower - up to 2.5 gallons of water flow per minute; typical faucets - up to 2 gallons of water flow per minute.

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.
