Never run out of hot water again with the Rinnai RE199iN natural gas non-condensing tankless water heater, the perfect blend of high efficiency, reliable comfort, and great value for your home. Ideal for small to medium-sized residences or remodeling projects, this unit is engineered to provide an endless supply of hot water, giving you up to double the lifespan of traditional tanks. Despite its powerful output of up to 199,000 BTU, the RE199iN is about the size of a small suitcase (only 27.28" H x 14.05" W), making it incredibly easy to install indoors, even in tight spaces. It's also Wi-Fi capable and can be recirculated, adding a layer of modern convenience and allowing you to save even more energy. Enjoy peace of mind and the luxury of constant hot water with Rinnai's reliable design.

Optimized Concentric Venting for Non-Condensing Models
Rinnai Tankless Water Heaters were the first to use a unique concentric venting system – featuring an inner pipe for exhaust and an outer pipe for fresh air from outdoors. The result is a direct-vent, sealed combustion system that requires only one penetration through the wall or roof.
