Noritz Launches EZ Tankless Series to Simplify Replacement of Larger Residential Tank Units in North American Market
Noritz’s new EZ Series of ultra high-efficiency tankless water heaters offer top-mount water connections and multiple venting and location options for faster, easier, less costly replacement of larger tank water heaters.
FOUNTAIN VALLEY, CALIF. (APRIL 11, 2017) — Engineered expressly for the North American residential market, the EZ Series of high-efficiency, condensing tankless water heaters from Noritz America are designed to cut installation time and cost when replacing larger, storage tank-type units. The Energy Star-rated EZ98-DV and EZ111-DV (Energy Factor: 0.97) join the previously released EZTR40 to provide professional installers and their homeowner-customers with a wider range of tankless options, covering the majority of residential, tank-replacement opportunities.
The EZ98-DV has a maximum input of 180,000 BTUs per hour (BTU/hr) and a maximum flow rate of 9.8 gallons per minute (gpm), making it generally suitable for homes with up to three baths.
The EZ111-DV, with inputs up to 199,900 BTU/hr and flow rates to 11.1 gpm, is intended for homes with up to four baths.
Like the EZTR40, unveiled in 2014, the two larger models offer features not found on other residential tankless units in North America – all intended to ease the installer’s job and lessen the homeowner’s up-front investment. These include:
top-mount, hot- and cold-water connections that sharply reduce the amount of new plumbing work required by a tankless-for-tank replacement;
maximum venting flexibility with four different options, including outdoor (OD), direct vent (DV), single vent (SV) and 2-inch flex vent, which utilizes the existing B-Vent formerly used by the tank water heater being replaced;
the possibility of reusing the tank unit’s half-inch gas line, thus avoiding the substantial expense of running a new gas line.
In addition to being offered separately for indoor or outdoor installation, both new units are available in their own “EZTR Bundle” packages (EZTR50 and EZTR75, respectively) that include materials and accessories for direct indoor replacement of 50- and 75-gallon, tank-type water heaters.
“The EZ Series of condensing tankless water heaters is redefining the entire residential water heating industry in the United States and Canada with its streamlined approach to direct tank replacement,” says Jason Fleming, VP of Sales and Marketing for Noritz. “No other tankless water heater offers the same ease of installation and versatility.”
A detailed look at the versatile EZ Series and its installer-friendly options:
Top-mounted water connections: Both new EZ models have their hot- and cold- water connections located on top of the unit – not the bottom, like most tankless heaters. This positioning allows the flexible water lines used by the previous tank heater to be quickly and easily reconnected to the new unit. Not only does this save time and money traditionally spent purchasing and running new plumbing around the tankless unit, but it also gives the final application a cleaner look.
Multiple venting options: The EZ models can each vent using dual- or single-pipe (made of PVC or CPVC), as well as 2-inch Flex, which can be fed through the existing B-Vent – again saving time and material. (Note: The choice of a single-pipe versus a dual-pipe configuration will depend on the air quality of the particular application.) Furthermore, multiple-unit installations for very large applications can use common venting if vent space limitations are an issue.
Half-inch gas line capability: Both new units can potentially use the same half-inch gas line as the tank units they are replacing, depending on incoming gas pressure and the distance of the water heater from the gas meter. The installer should make the final determination.
Outdoor installation: The new EZ Series also includes outdoor models for warmer climates.
Dual, stainless steel heat exchangers: Inside each EZ model are two stainless steel heat exchangers that have a greater resistance to corrosion and scale buildup than copper, thereby boosting system life.
Ultra low-NOx Eco-Burner: The fully modulating burner has a nitrogen-oxide emissions level of only 14 parts per million (ppm), far exceeding the South Coast Air Quality Management District requirement of 20 ppm.
Premix Burner: The premix burner optimizes the air/fuel ratio based on demand for better efficiency with fewer moving parts.
High altitude performance: The EZ Series can perform at an altitude of up to 10,000 feet.
WiFi-enabled: The Noritz Connect app is compatible with both of the new units, allowing for wireless remote control of heater functions, as well as diagnostic and maintenance reminders.
Accessories: Available accessories for the EZ Series include a wireless adaptor, outdoor vent cap, flex vent 2-inch conversion kit, 2-inch SV conversion kit, and PVC concentric termination.
Approved in Canada: The EZ Series has been approved for use in Canada.
The EZTR Bundle Option
A major benefit for contractors looking to further streamline the tankless-for-tank replacement job is the availability of each EZ model in a “Bundle” package for indoor installation. Each combo package includes the heater itself, a flex vent conversion kit (comes with 25 feet of 2-inch flex), an isolation valve kit, and a startup guide.
Three bundles are available:
The EZTR40 package is designed for quick and direct indoor replacement of 40-gallon tank water heaters.
The EZTR50 package contains the new EZ98-DV, plus all the aforementioned components, for replacement of a 50-gallon tank water heater.
The EZTR75 package contains the new EZ111-DV, plus all the aforementioned components, for replacement of a 75-gallon tank water heater.
“The professional installer wins no matter how he or she purchases the new EZ models,” explains Fleming. “By itself, each unit offers contractors total flexibility in venting and indoor/outdoor installation. Buying an EZTR Bundle allows for direct indoor replacement without having to even think about sizing – just buy and replace.”
The EZ models and their corresponding EZTR Bundles will be available for shipment to Noritz distributors in May 2017 and will include a 12-year warranty on heat exchangers, five-year warranty on parts and one year on labor.
