Maximum Performance
that Lasts Longer
Easy installation, superior performance and longer life mean there
has never been a better time to switch from traditional tanks to
the consistency and eciency of Demand Duo® H- and R-Series
solutions.
How Demand Duo
®
Works
Water heats in the tankless unit rather
than inside the tank, providing:
• Zero thermal stress on the tank
• More hot water capacity, since tank only
holds two magnesium anode rods
• Easy, cost-eective tankless maintenance
versus replacing an entire tank every few years
• Ideal for emergency replacement;
installs like a tank but up to 20% lighter
