A ScaleCutter system can serve a tankless unit or whole home. As water passes through, a small amount of scale control product is dissolved into the water stream. It helps to soften and remove existing scale over time.

 

    Multiple Venting Options

    Venting available in vertical and horizontal configurations. Concentric structure allows hot exhaust to exit through interior tube, while fresh air enters through the outer layer.

     

    Concentric Venting for HE and HE+ Series

    Rinnai Tankless Water Heaters were the first to use a unique concentric venting system, a single vent assembly option featuring an inner tube for exhaust and an outer tube for fresh air from outdoors. The result is a direct-vent, sealed combustion system that offers optimum safety and performance.

    Venting For SE and SE+ Series

    The SE and SE+ models offer concentric polypropylene or dual-pipe PVC/CPVC/PP venting options on the same model. The dual venting configuration on the top allows for maximum flexibility for installers and dealers — one concentric vent or two PVC/CPVC/PP pipes can be used for venting.

    The Condensate Neutralizer Kit can be used with Rinnai Condensing Boilers and Tankless Water Heaters. By raising the pH level of the condensate before the water discharges to the drain, the kit can prevent damage to the pipes and enhance the performance of the unit.
