Rinnai Tankless Water Heater Accessories

Your Rinnai is great on it's own. It's only perfect with the right accessories for your needs. The new WiFi controller makes it easier to control your Rinnai. A re-circulation pump adds instant hot water and combined with both, you can use a push button to have instant hot water without your phone!
