About Tankless & hybrid water heaters

Most of this shelf is tankless: units that fire only when a tap opens, so there is no stored water losing heat between uses. The condensing models recover heat from their own exhaust and can vent in plastic pipe; non-condensing models cost less up front and need a metal or concentric vent. Check three things against your site before ordering: the gas type (N is natural gas, P is propane), indoor versus outdoor placement (i or e in most Rinnai model numbers), and the flow you need at your incoming water temperature.
