Rinnai is the best-known name in gas tankless water heaters, and its lineup (indoor and outdoor models, natural gas or propane) is the benchmark most rivals are measured against. These units heat water on demand instead of storing it, so you get endless hot water and a small wall-mounted footprint. Energy Star models are efficient, but output varies a lot by model, so match the unit's flow rate to your household. Reviewers rate them well overall, praising hot water supply and build quality while noting install cost and maintenance.
