From Rheem Water Heaters
Single-source Heating and Hot Water
Product From Rheem Water Heaters
Rheem Manufacturing Co. has introduced its Integrated Heating & Water Heating System powered by tankless technology. The product offers home heating and hot water from a single source that circulates hot water through a hydronic air handler to provide warm air at comfortable humidity levels. The hot water then is recirculated back to the tankless water heater to avoid waste.

A.O. Smith includes a digital interface for easy programming within their entire line of conventional and condensing tankless water heaters. The condensing tankless line feature Energy Factors up to 0.91, are Energy Star qualified and are eligible for a federal tax credit. The line also includes a 12 year limited warranty.
Ultra Series Condensing Water-Heating Technology
Product From Rinnai America CorporationRinnai incorporates two heat exchangers with their Ultra Series Condensing Water-Heating Technology to achieve maximum heating value while earning an Energy Factor rating of up to 0.96. The down-fired ceramic burner allows condensation to drain from the bottom of the heat exchanger, protecting the primary heat exchanger and burner. Each unit comes standard with circ-logic technology and timer controller, which allows for recirculation patterns to be set to coincide with household usage patterns.
Electric Tankless Water Heater
Product From EcoSmart USEcoSmart features flow-activated control and durable, threaded, copper heating elements in their Electric Tankless Water Heater. Emerson Electric heating elements come standard in all models and are made of either copper or stainless steel. All models include a lifetime warranty, and many models include digital temperature control and flow sensor technology, which activates the unit by switching the power either on or off to the heating elements instead of modulating.
Tempra Plus Tankless Electric Water Heater
Product From Stiebel EltronStiebel Eltron provides ideal backups for solar thermal systems in their Tempra Plus Tankless Electric Water Heaters. Featuring advanced flow control, the tankless electric water heaters automatically keep output temperature constant and supply a continuous hot water flow. The units are space saving at 17-by 15- by 5-in. Also, all tankless, on-demand, electric water heaters include a three year warranty.
NRC661 Condensing Tankless Water Heater
Product From NoritzThe Noritz NRC661 Condensing Tankless Water Heater delivers 6.6 gallons per minute, with a maximum input of 120,000 BTU per hour. Using a half-inch gas line up to 120-ft. in length, the tankless water heater is designed for two-bath residences in warm weather climates. It has an Energy Factor of 0.91 for natural gas and 0.93 for LP and is equipped with a fully modulating, low NOx Eco-Burner that eliminates the need for a buffer tank to stabilize the temperature. A built-in digital display allows basic servicing without needing a remote and troubleshooting by indicating flow rates, temperature and common error codes.
Rheem’s new High-Efficiency Condensing Power Direct Vent (PDV) Water Heater is Energy Star-qualified and uses condensing technology in a residential, tank design. It delivers more heat to the water, so less heat exhausts from the vent. The cooler flue gases permit venting through 2" or 3" PVC piping. The heater is available in 48- and 38-gallon capacities.
The StarMax V solar water heating collector for pumped glycol and drainback systems from Caleffi is shaped similarly to a standard four-outlet collector but has a fifth outlet at the bottom center and has sloped internal upper and lower headers. This combinations allows fluid to drain without the need to pitch the collectors. The array can be mounted plumb and level on a roof. The temperature well is directly connected to the absorber for accurate sensing.
Gas-condensing Tankless Water Heater
Product From Navien AmericaNavien America Inc.’s NPE Series of premium gas-condensing tankless water heaters use existing 1/2-inch gas lines and flue chases to ease the installation process. It has dual stainless steel heat exchanges, ultra-low NOx emissions and field convertibility from natural gas to liquid propane gas. The heaters have a 98 percent heating efficiency and can operate at altitudes up to 10,000 feet.
Extreme Recovery Gas Water Heater
Product From Rheem Water HeatersThe Rheem XR90 Extreme Recovery Gas Water Heater has a 29-gallon capacity yet at 40,000 BTU per hour can deliver more hot water than a 50-gallon gas water heater. The unit has a first-hour rating of 90 gallons, which means homeowners get three times the amount of hot water in an hour than what the tank holds. It costs 17 percent less to operate annually compared to a 50-gallon gas water heater.
Rinnai America Corp. has released its Scale Control System, an accessory that helps tankless water heaters perform optimally with hard water, in which mineral deposits can affect a unit’s efficiency and shorten its lifespan. The Scale Control System may be installed on a home’s cold-water line in front or upstream of a tankless unit. The system dissolves a blend of compounds into the water stream, delivering scale control without electricity. The cartridge, which should be replaced every 10 to 12 months, is translucent so owners can see when replacement is necessary.
