The Rheem RTG is a mid-efficiency, indoor tankless gas water heater built for continuous hot water on demand. It is an ultra low NOx unit, which matters in areas with strict air-quality rules. It suits households replacing a tank heater who want endless hot water and a smaller footprint, and it costs less than Rheem's high-efficiency condensing models. The trade-off is that mid-efficiency units vent through a single metal pipe and lose more heat up the flue than condensing rivals.
