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.
