Noritz America, an international leader in tankless and electric heat pump water heaters and high-efficiency combination boilers, has further enhanced its EZ Series Pro line of residential condensing tankless water heaters.
The company has expanded the size and the functionality of the units' built-in control panel, which is mounted on the front exterior.
Providing upgraded monitoring and diagnostic capabilities, the multi-function panel display allows professional installers to view system status, temperature settings, service reminders, maintenance data, error codes, error history, and (if applicable) recirculation timing settings.
All of this vital information is built in and readily accessible on the water heater. Besides eliminating the need for a separate, external remote controller, the panel enables guided setup during installation and faster, more effective troubleshooting.
In addition, installers and users can monitor and program the unit remotely via Bluetooth connectivity that works alongside the panel, using the EZ Start Plus app on their smartphones. A separate external remote is optional.
Noritz executive vice president and general manager Jason Fleming said the goal of the upgrade was to create a more satisfying user experience for both the professional and the consumer.
“We focused on simplified installation, advanced diagnostics, and giving professionals and their customers easier, more responsive control of the water heater,” Fleming said.
Professional installers and service technicians will find it easier to use the enlarged panel to set the output water temperature to 100° - 140° Fahrenheit. Temperature settings are available in increments as small as 5°F.
This means more precise temperature control. Moreover, the EZ Start Plus app enables installers and service techs to perform system setup, adjust the temperature, run diagnostics and share this information electronically with Noritz Technical Support. Installers can even register the water heater to qualify for the accompanying warranty.
The upgraded EZ Series Pro continues to include three models, all with a Uniform Energy Factor of 0.98, the highest efficiency rating in the tankless water heater industry.
All three units carry a 25-year limited warranty on their stainless steel heat exchangers, the longest such protection in the industry. Further protection includes a five-year limited parts warranty and one year for reasonable labour.
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 two-, three-, or four-inch Schedule 40 or Schedule 80 PVC or CPVC, or two-inch or three-inch polypropylene venting.
They can also be installed outdoors in milder year-round climates using an optional vent cap.
