When you need a quick simple replacement for a standard tank-style unit, Rinnai’s Demand Duo™ 80-Gallon Hybrid Water Heating System is the smart choice. With connections similar to most tanks, this direct-replacement solution combines the best of tank and tankless technologies, delivering cost savings and consistent hot water.

WATER HEATING THAT PERFORMS AND PROTECTS YOUR INVESTMENT

As the heat source, the RL94 tankless unit eliminates thermal stress on the tank, lengthening the life and maximizing performance of the system while efficient tank recovery methods save energy and deliver consistent hot water, even during reheat cycles. Best-in-class performance coupled with Demand Duo’s innovative sustainable design allows for easy service of the tankless unit versus replacing the entire tank, greatly reducing life-cycle costs.
