3 PUMBING-HEATING-COOING CONTRACTORS ASSOCIATION Tankless Advantage With a properly sized Noritz, you won t have to worry about running out of hot water. You will also be heating that water efficiently, saving energy and money. Endless Hot Water Since a Noritz tankless heats water on demand, the incoming water is heated as it passes through the heat exchanger, which delivers endless hot water. Safety Comfort and safety is one of the highest priorities when it comes to Noritz. Our units are equipped with safety features to prevent scalding water from exiting your fixtures. Higher Volume Two identical units* can be linked together to double the output or for even higher demands. Up to units* can be linked together to maximize output. (*Select models only.) Clean Water With a tankless, you won t be using hot water that is stored in a tank that can accumulate scale and rust over time, or even worse possible egionella bacteria. ENERGY STAR Qualified Noritz residential models meet or exceed the criteria set forth for ENERGY STAR qualification. With ENERGY STAR certification, you can rest with confidence a Noritz tankless will save energy and money. How Much Can Your Family Save By Going Tankless? Annual Savings ($/Year) $00 $0 $00 $0 $00 $0 $ $0 Family Size $7 $0 $0. On emand. Tankless water heaters heat water only when needed, eliminating the wasteful energy use of reheating stored hot water, which is standard with tank-type water heaters. NR-O NR98- NR98-C NR98-O.

6 Noritz Commercial The Noritz Commercial Advantage Modular The Noritz modular system is based on a single self-contained, interchangeable unit that can combine and communicate with like units to meet any hot water demand. Modulation Noritz fully modulating technology can track any hot water demand with pin point accuracy, only using the energy necessary to heat the water that is used. Fully Modulating Burner Noritz's fully modulating burner technology is the most precise and efficient method of heating high fluctuating demands of water. Single Unit : Turndown Ratio,000-0,000 BTU Range Units (Modular) : Turndown Ratio,000- Million BTU Range Intelligent System In a multi-system setup, the Noritz (Specs based on NC0 model) commercial units will communicate with one another and work in unison to even out the load on each individual unit, maximizing output and system life. With the ability to modulate between multiple units with the use of a system controller makes Noritz commercial water heaters the most efficient water heating system on the market today. 80% 0% 0% 0% The heater will turn on when the flow is sensed. 0% 0% heater will work solely until the demand grows greater than 80%. The load will equalize among or more heaters to meet high volume demand. NC80--ASME NC0--ASME NC0--ASME imensions 9.7 (H) x 9. (W) x.8 (epth). (H) x 8. (W) x 9. (epth). (H) x 8. (W) x 9.

7 PUMBING-HEATING-COOING CONTRACTORS ASSOCIATION Advantages Redundancy Any one of the Noritz commercial units on a multi-system can be taken offline and serviced without compromising your business. Hot water will still be provided by the other units. Efficiency Because of the modulating technology, a Noritz commercial system heats water using only the energy necessary to meet the demand, reducing energy consumption significantly and saving on water heating costs. Versatile Installation Noritz commercial units can be installed indoors or outdoors and because of its size and weight, they can be wall hung or racked, making spaces once thought impossible, possible. Noritz Commercial Installation Noritz tankless water heaters were installed at the headquarters of a sunglass manufacturer in ake Forest, CA. This job has a total of NC80--ASME with 0 multi-system units, and multi-system units. These units supply hot water to lens cleaning machines. Electric tank water heaters were previously used on this installation but were not able to supply the demand of the lens cleaning machines, which are operated twenty-four hours a day. The Noritz units are able to supply an endless stream of hot water and save much needed room within the building as well. Condensing NCC99- Condensing NCC99- NC99-C NC99-O. (H) x 8. (W) x 9. (epth).
