(PEACHTREE CITY, Ga. – Jan. 23, 2012) - Rinnai Corporation, manufacturer of the No.1 selling tankless water heater brand in North America, is launching two accessories to enhance its condensing product lines at this year’s Air-Conditioning, Heating, Refrigeration Exposition (AHR Expo). The company’s new condensate neutralizer accessory removes acidity from the condensation that is produced by a condensing tankless water heater or boiler, ensuring that it has a neutral pH level in accordance with select state requirements. Rinnai is also introducing a dual pipe venting system for its condensing tankless water heaters that utilizes a 3-inch polypropylene pipe to provide installers and homeowners with increased placement flexibility and installation options.

“At Rinnai, we’re constantly working to identify new products and programs that simplify the sale and installation of our water heating and home heating units,” said Rinnai Vice President of Marketing Brad Sweet. “We brought the condensate neutralizer and dual venting option to market specifically to address the needs of installers that work with Rinnai’s condensing technology. The addition of these accessories helps to round out our portfolio of solutions for installers while ensuring the smoothest installation possible.”


Rinnai’s new condensate neutralizer accessory provides installers with an effective way to eliminate acidity from the condensation that is drained from a condensing boiler or condensing tankless unit. The company introduced the easy-to-install feature because select states require condensate from condensing appliances to be treated before passing into a public sewer system. Rinnai’s condensate neutralizer works by running the condensation through a container filled with limestone media, which raises its pH level to make the liquid less acidic, resulting in neutral water that can be drained directly from the unit. Designed for both vertical and horizontal mounting, the condensate neutralizer’s user-friendly clear capsule design allows homeowners to see when the limestone media needs to be replaced. Additional limestone can be purchased from a Rinnai installer.

“The condensate neutralizer is quickly becoming an essential component of condensing product installations in many markets,” said Rinnai Product Management Specialist Tracy Young. “Because we expect the number of states requiring the neutralization of condensate to grow, Rinnai proactively introduced this solution to make acidity a non-issue for our condensing units.”


Rinnai is also introducing a dual pipe venting option for its condensing tankless water heaters. The new system, which connects to Rinnai’s standard concentric vent via a concentric twin pipe adaptor, enables a greater variety of installation options by accommodating venting in tight spaces, such as between a ceiling and subfloor, and making raised terminations easier and less expensive. Each pipe is 3 inches in diameter, so the system is ideal for long vent runs, and because it allows for greater distance between the intake and exhaust terminations, the potential for condensation from the unit to freeze over the intake in very cold climates is virtually eliminated.

The new system’s exhaust pipe venting is a product called InnoFlue®, which is produced by Centrotherm EcoSystem and is made of the same polypropylene material that is found in Rinnai’s condensing concentric venting. With a maximum temperature rating of 230° F, polypropylene is specifically engineered and certified for use with condensing tankless water heaters. The new InnoFlue® venting offers the zero clearance to combustibles benefit of Rinnai’s standard concentric venting, a 10-year warranty, and positive fit and lock for secure joints without cementing or curing. In addition, InnoFlue® venting is 100% recyclable and earns points toward Leadership in Energy and Environmental Design® (LEED) certification because it does not use solvent-based primers and adhesives.

“Rinnai’s dual pipe venting system addresses many common installation complications and enables more homeowners to enjoy the benefits of our condensing tankless water heaters,” said Rinnai Global Product Manager Trey Hoffman. “By making condensing tankless technology available to a wider array of homes, we believe the dual pipe venting system will help expand our installers’ customer base.”
