Commercial Water Heating

1. High Efficiency2. Reliability via Quality, Redundancy3. Flexible Application Locations4. Simple Installation…by Design5. Reduced Cost of Ownership



It all starts with one Rinnai tankless water heater…



Commercial Water HeatingApproach - Provide innovative water heating solutions using

multiple tankless water heaters working together.

• Modulates from 15.2K BTU to 199K BTU (0.4 gpm – 9.8 gpm)

• High Temperature up to 185°F• Available with built in recirculation pump

96% High Efficiency Condensing Technology



Modulation = Turndown RatioWhat is turndown ratio?

The description of a gas products ability to modulate its flame and BTU delivery

Modulation is defined by Turndown Ratio

Turndown Ratio: A products maximum fuel input divided by its minimum fuel input.

C199 Example: One 199,000 btu tankless water heater a minimum fuel input of 15,200 btu’s would have turndown ratio of 13:1

199,000 divided by 15,200 = 13:1 Turn Down Ratio (TDR)



Modulation = Turndown Ratio = Load Tracking

Reliability via Product Quality



Reliability via Redundancy

Individual Tankless Can Be Taken Off Line With No Interruption of Hot Water Service



Example: 1,000,000 btu System

One unit disabled: 50% loss of DHWTank disabled: 100% loss of DHW

One unit disabled: loss of 16% DHW
