The Next Generation in Hybrid Technology
Replace your standard efficiency atmospheric tank with the latest water heating technology—Demand Duo® R-Series.

Now with More than 2X the warranty of most traditional tanks and NEW Features that Simplify Installation and Optimize Performance.

Unsurpassed Warranty

Demand Duo R-Series delivers reliable performance because water is heated inside the
tankless, NOT the tank. This eliminates thermal stress which leads to a longer service life and
a lower total cost of ownership than other traditional forms of commercial water heating.

solution when replacing traditional atmospheric tank-type water heaters.
