Save time, energy and money with Rinnai's hybrid solutions. The tank/tankless systems offer reliability, built-in redundancy and performance, ensuring "no hot water" events that adversely affect profit are a thing of the past.
No matter your industry, Demand Duo® can meet the demand, with first-hour delivery of 546 gallons and 463 GPH recovery (at 100°ΔT). Plus, with two tankless units delivering 398 BTUs as the heat source, the system greatly reduces thermal stress on the tank, prolonging its life.
The latest technology of Demand Duo® and a high-quality installation from a Rinnai PRO makes this a quick and easy upgrade from a standard tank or boiler system — for both emergency and planned installs.
Every Rinnai system is individually tested for quality before shipping. Unlike many competitors, Rinnai makes the majority of our key components, allowing for consistent control of quality. That’s why more consumers and businesses choose Rinnai over any other tankless brand.
The most venting options Rinnai has ever offered: Concentric 2” x 4” or 3” x 5”, twin pipe, common vent with polypropylene or PVC/CPVC and our new flex vent option.
There’s no need to purchase multiple tanks or boilers when the Demand Duo® 2 can do double the work while greatly reducing capital and equipment and operating costs.
Our team of application engineers is available to provide quotes, size your system and provide designs for your specific project — all at no charge and backed by our 100% system sizing guarantee.
