Noritz EZ Series Key Specs
Flow Rate: 11.1 GPM
This value indicates the volume of hot water the unit delivers each minute. An 11.1 GPM rating supports multiple simultaneous uses, such as two showers and a kitchen sink. You benefit from consistent pressure during peak hours. When shopping, compare this figure against your household’s total demand to ensure the heater keeps up with your usage patterns without temperature drops.
BTU: 199,900 BTU
BTU measures the heating power of the gas burner. A 199,900 BTU input provides the energy needed to raise water temperature quickly. Higher BTU units handle colder incoming water more effectively. You should compare this heating capacity with your local groundwater temperature to verify it can maintain desired output heat during winter months for reliable performance.
Voltage: 120 V
This specifies the electrical requirement for the unit’s control board and ignition system. A 120 V connection allows you to plug the heater into a standard household outlet. It simplifies installation by avoiding complex high-voltage wiring. When comparing models, check if your home has accessible 120 V circuits near the installation site to avoid additional electrical upgrades.
Dimensions: 11.8 x 18.1 x 26.1 in
These measurements describe the physical footprint of the heater. The compact design fits into tight utility spaces or exterior walls. You benefit from flexible placement options in small homes or apartments. Compare these dimensions with your available mounting area to ensure the unit fits without obstructing access or requiring structural modifications to your home.
Fuel Type: Natural Gas
This indicates the heater runs on natural gas rather than propane or electricity. You benefit from lower fuel costs if your home is already connected to a natural gas line. It also ensures consistent supply without tank refills. When shopping, confirm your property has natural gas infrastructure, as this fuel type dictates the necessary piping and venting requirements for safe operation.
Design and Build Overview
According to the listing, the Noritz EZ Series Pro features a silver finish on its exterior. This color choice helps the unit blend into various residential settings, whether mounted indoors or outdoors. The casing is designed to be compact, measuring 11.8 inches in length, 18.1 inches in width, and 26.1 inches in height. These dimensions allow for flexible placement in tighter utility spaces where larger traditional tanks would not fit.
The unit weighs 77.2 pounds. This weight suggests a sturdy internal construction capable of withstanding standard residential plumbing pressures. The compact footprint ensures it does not dominate a garage or utility closet. You can mount it on exterior walls as well, thanks to its indoor/outdoor rating. This dual capability provides installation flexibility for different home layouts.
The design prioritizes reliability and performance. The natural gas fuel type means it connects directly to your home’s gas line. The 120-volt electrical requirement powers the control electronics and ignition system. This low voltage draw simplifies the electrical setup compared to higher-voltage models. The overall build focuses on efficient space usage and durable materials suitable for year-round operation in various weather conditions.
