THIS CONDENSING TANKLESS WATER HEATER incorporates two heat exchangers to deliver up to 95% thermal efficiency. The Energy Star qualified appliance is offered in four models to meet the needs of almost any residential application, and can be banked in manifolds for even greater capacity. Features include a concentric venting system with a polypropylene inner pipe designed to withstand varying flue temperatures. The system uses just one pipe that is fit and locked into place without glues or solvents. Expandable gasket seals at the pipe joints virtually eliminate the risk of gaps.
