Rinnai RE and REP Series Non-Condensing Tankless Water Heaters
Rinnai’s RE and REP Series tankless water heaters deliver continuous hot water, premium efficiency, and trusted performance for homes that want endless comfort without wasted energy. Designed to heat water only when you need it, these non-condensing tankless units free up space, reduce standby heat loss, and provide consistent temperature control for showers, appliances, and whole-home use.
The RE Series offers high-efficiency Non-condensing technology with ultra-low NOx performance and built-in Wi-Fi monitoring on select models. These units are ideal for households that want strong flow rates, quiet operation, and long-term reliability in a space-saving design.
The REP Series includes the same Non-condensing technology but adds an integrated pump for faster hot-water delivery in recirculation systems—perfect for homes with long pipe runs or areas where hot water takes too long to reach the tap. The built-in pump supports multiple recirculation modes, including dedicated return lines and thermal bypass options.
Both series feature smart diagnostics, scale detection, easy front-panel maintenance access, and durable stainless-steel heat exchangers engineered to last. Whether upgrading an older tank system or building a high-efficiency plumbing layout, Rinnai tankless models offer energy savings, lower operating costs, and a continuous supply of hot water sized to your home’s needs.
