Precisely engineered accessories can add even more reliability, convenience and flexibility to Rinnai Tankless Water Heaters. With Rinnai Common Venting, up to 8 tankless water heater units share the same vent system. This allows for significantly fewer wall or roof cuts, less labor, and longer vent lengths than ever possible with single-unit tankless water heater venting.
