Noritz America has enhanced its EZ Series Pro line of residential condensing tankless water heaters by expanding both the size and the functionality of the units’ built-in control panel.
Providing upgraded monitoring and diagnostic capabilities, the multifunction panel display allows professional installers to view system status, temperature settings, service reminders, maintenance data, error codes, and error history.
In addition, installers and users can monitor and program the unit remotely via Bluetooth, using the EZ Start Plus app on their smartphones. A separate external remote is optional.
“The intent of our upgrade efforts was to create a more satisfying user experience for both the professional and the consumer,” says Noritz executive vice president and general manager Jason Fleming. “We focused on simplified installation, advanced diagnostics, and giving professionals and their customers easier, more responsive control of the water heater.”
The upgraded EZ Series Pro continues to include three models, all with a Uniform Energy Factor of 0.98:
- EZ71: input range — 12,800 to 160,000 BTU/hour; flow rate — 0.4 to 9.0 gallons per minute; turndown ratio — 12.5:1
- EZ98: 12,800 to 180,000 BTUh; 0.4 to 9.8 gpm; 14:1;
- EZ111: 12,800 to 199,900 BTUh; 0.4 to 11.1 gpm; 16:1.
The water heaters use natural gas but are field-convertible to LP with a parts kit included with every unit. Two water heaters can be linked using Noritz’s optional Quick Connect linkage to double the hot-water flow rate.
Designed for wall-mounting indoors, the EZ Series Pro heaters can be direct-vented with 2-, 3-, or 4-inch Schedule 40 or Schedule 80 PVC or CPVC, or 2-inch or 3-inch polypropylene venting. They can also be installed outdoors in milder year-round climates using an optional vent cap.
