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 Rheem TanklessGT-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
