The new RTG-66DV direct-vent, gas-fired tankless water heater from Rheem meets the hot water needs of a two- or three-bathroom residence, yet takes up no more space than a medicine cabinet. It saves space and reduces installation time through its use of concentric venting. Instead of separate Category III stainless-steel vent runs for the fresh-air intake and exhaust lines, RTG-66DV expels combustion by-products through a 3-inch exhaust pipe that sits inside the 5-inch intake run, thus eliminating the second line.
