10 Year Warranty. The Rinnai INFINITY A26 LPG is a high-capacity continuous-flow gas water heater designed for external residential installation. It delivers up to 26 litres of hot water per minute at a 25°C rise, giving busy New Zealand households dependable hot water for simultaneous showers, kitchen use and everyday cleaning without storing a full cylinder of heated water.
Its on-demand operation heats water only when required, while direct electronic ignition, fan-forced exhaust and automatic frost protection support reliable year-round performance. The compact outdoor-mounted design also helps preserve useful indoor storage space.
