The Rinnai High Efficiency is a non-condensing indoor tankless water heater rated at 180,000 BTU and up to 8.5 GPM, enough for a large household running several fixtures at once. It is a workhorse gas unit with a 15-year limited heat exchanger warranty, Wi-Fi compatibility and an ultra-low NOx burner. It is not a condensing model, so its 0.82 Uniform Energy Factor trails condensing rivals that recover heat from exhaust. Reviewers of this Rinnai line generally praise the steady hot water and long service life, while noting the cost of professional venting and installation.
