A.O. Smith 540P series tankless water heaters
The 540P series integrates a recirculation pump to provide instant hot water in residential applications with dedicated recirculation lines. The pump is easily controlled with a simple user interface, and multiple pump settings allow you to customize pump operation to meet your needs while maximizing heater efficiency. The onboard computer modulates combustion to yield an EF of 0.95 while meeting the strictest gas emissions standards. As part of the high efficiency tankless family, the 540P series provides instant hot water while being environmentally friendly.

AERCO Innovation tankless water heater
The Innovation tankless water heater provides consulting-specifying engineers, plumbers, building owners and facilities management with technologies, products, and service and support to simplify installation, improve water heating system performance, and lower operating costs. It features up to 99 percent efficiency and a tankless design, which allows outlet temperatures to be set to 120 F without the risk of Legionella. Innovation also has tight temperature control of +/-4 degrees. The inherent high uptime reliability of Innovation is supported by the AERCO OnAER Remote Monitoring Service, a proactive tool that prevents unexpected downtime and lost revenue while optimizing system performance.
Other features include a dual-fuel gas train for natural gas and propane so the water heater can operate under extreme conditions, a turn down ratio as high as 30:1, the AERCO Smart Size Water Heater Selection Program, and integration with C-More controls that feature the WHM II water heater management program, which allow for easy sequencing of up to eight units. Innovation is available in four sizes — 600, 800, 1060 or 1350 MBH.
Bosch Greentherm 9000 tankless water heater
The Bosch Greentherm 9000 Series offers nine models for high-efficiency domestic hot water in residential or commercial applications, adding new features for easy installation, operation and maintenance. The series features an EF of 0.99 with thermal efficiency of 100 percent, which is the highest in the industry for condensing gas water heaters. It also achieves temperature stability of +/-2 degrees through the active bypass, which provides unparalleled temperature stability and eliminates the need for a buffer tank, even with varying flow rates and supply water temperatures. The premium Greentherm 9900i SE model has a unique, stylish glass front and integrated Wi-Fi control enabling the homeowner to control the water heater remotely with a free mobile app.
Bradford White Infiniti tankless water heaters with SRT
The Infiniti tankless water heaters combine the energy- and space-saving features characteristic of tankless water heaters with new technologies and designs that significantly reduce scale build-up, reduce maintenance, improve performance and provide greater installation flexibility. Each unit is equipped with the SRT Scale Reduction Technology system, which uses multiple components to reduce scale by disturbing water flow and greatly reducing hotspots that allow scale to accumulate.
To minimize water temperature fluctuation during hot water usage, the Infiniti condensing model is equipped with an automatic and fully modulating bypass. Together with temperature sensors located throughout the unit, temperature stability throughout the draw remains consistent resulting in a better user experience.
Giving design engineers and installing contractors a wider array of venting options and configurations, the Infiniti condensing model is approved for use with PVC, CPVC, ABS and polypropylene, and is available with an optional “up and out” concentric vent kit requiring only one penetration through the wall or roof.
The water heaters are ENERGY STAR qualified and include both condensing and non-condensing residential models with 199,000 BTU inputs. Additional features include an easy-to-use, built-in digital control, built-in freeze protection, low NOx emissions, an optional outdoor installation kit, and a limited 12-year warranty on the heat exchanger and a limited five-year warranty on all parts.

Eemax skidded combo systems
Eemax now offers skidded systems, pairing electric tankless water heaters with storage tanks to reap the best benefits of both products. These skidded combo systems can handle low-flow and high-flow dump applications equally well. A temperature control switch activates a pump, which circulates water through the tankless heater, eliminating issues with low flow turn-on and decreasing the peak power-sizing requirement. Eemax can size and fabricate the entire skidded system, floor-mounted or wall-hung, based on the customer’s demand and electrical capacity.
Intellihot Gen II
The Gen II, part of the iQ series and iSeries commercial tankless water heaters, comes equipped with an intuitive touch screen, is IoT and Wi-Fi enabled, and can be monitored remotely with a new state-of-the-art mobile app. Intellihot has also launched the telliZero service which provides prognostics and ships parts ahead of time when any replacements are needed.
The water heaters are built for the most challenging commercial and industrial, large-scale applications. The energy-efficient and space-saving systems can lower your capital costs by 50 percent and operational costs by up to 60 percent.
Navien NPE Series tankless water heaters
The NPE-A series condensing tankless water heaters are ideal for both commercial and residential applications. The water heaters feature a ½-inch gas pipe capability, 2-inch PVC venting, dual stainless steel heat exchangers, ComfortFlow recirculation including pump and buffer tank, field gas convertibility and an elegant compact design. Up to 16 units can be cascaded together without an external control and 8 units may be common vented. Highly efficient at 0.97 EF or 0.96 UEF, NPE-180A, NPE-210A and NPE-240A are also available with on demand activation and NaviLink Wi-Fi control. For installations where the internal pump and buffer tank are not required, Navien offers the DOE’s highest rated condensing tankless water heater, NPE-S standard in four sizes, with up to 0.99 EF or 0.97 UEF.
Noritz EZ Tankless Water Heater Series
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 (0.97 EF) 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. Both models include top-mount water connections, maximum venting flexibility and the possibility of reusing the existing tank unit’s half-inch gas line.
The EZ98-DV and EZ111-DV are also available in bundle packages (EZTR50 and EZTR75, respectively) that include materials and accessories for direct indoor replacement of 50- and 75-gallon, tank-type water heaters.
Rheem Prestige series condensing tankless gas water heaters
The Prestige series condensing tankless gas water heaters save water, energy and installation time. The line is equipped with the Water Savings setting, which can save homeowners up to 1,100 gallons of water per year. The Rheem exclusive Hot Start Programming feature provides continuous hot water without cold-water bursts. While the units in this line quickly pair with the company’s demand-based recirculation pump kit to provide instantaneous hot water at the tap. These models also have a flow rate of .26 GPM and minimum activation flow rate of .40 GPM. Built from the ground up with contractors in mind, the Prestige tankless water heaters ensure ease of installation and integrated diagnostics, such as the Maintenance Notice and Recirculation Timer settings. Plus, the units are compatible with 1⁄2-inch gas lines and have a built-in condensate neutralizer and low-cost PVC venting compatibility.
Stiebel Eltron Mini E thermostatic tankless water heaters
The Mini E thermostatic tankless water heaters are an electronically controlled version of the mechanical Mini water heaters. The electronic control board and automatic flow control allow Mini E models to deliver water at factory preset temperature of 100 F. Custom preset output temps are also available. They’ll maintain temperature, even with pressure fluctuations in the water supply, which is perfect for installations where output temperatures are limited by code.
Unlike the mechanical units, which will only service a single sink, the Mini E 6-2 can be plumbed to supply warm water to multiple sinks in warm climates. The unit offers a seven-year warranty against leakage and three years on all components.
