Easy as 1-2-3" for Rheem Tankless Selection
Rheem Tankless Water Heater Contrators' Brochure
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 Rheem Tankless 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, you should choose our GT-199 heavy-duty water heater. In some applications, our heavy-duty tankless water heaters are 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 Tankless Water Heater exclusive.
