The Rinnai RE199iP is a propane-fired, non-condensing tankless water heater rated at 199,000 BTU and up to 9.8 GPM, enough for a large household running several fixtures at once. It mounts on an interior wall, vents concentrically, and is rated for high altitude and mobile homes. Its 0.82 Uniform Energy Factor and ultra-low NOx rating put it in line with other high-efficiency non-condensing units, though condensing models squeeze out more efficiency. Owners like the endless hot water and small footprint; the main complaints are the cost of professional installation and the venting requirements.
