Grand Hall USA, Inc. 3838 West Miller Road Garland, Texas 75041 866.946.1096

Company History: In 1985, Grand Hall, the Eternal manufacturer, opened the U.S. office in Dallas. Today, the 200,000-sq.-ft. distribution facility built in 2003 utilizes state-of-the-art technology to enhance operations. The facility also houses customer support, administration and marketing. In 2006, Grand Hall launched the first Eternal hybrid water heater in the U.S. and won many industry accolades. The third generation of the Eternal hybrid series was released in 2010. Company News: Grand Hall now has Building Information
Modeling (BIM) files available for the Eternal hybrid water heater. By working with SMARTBIM, Grand Hall can provide 3D digital representations of the hybrid water heater. The BIM renderings will help architects and builders understand the spatial dimensions of our product and assist them with important architectural decisions. The Eternal floor and wall mounted BIM versions are available at
http://www.smartbim.com on the manufacturer objects webpage. Tankless Forecast: Grand Hall believes that the tankless
market overall will remain stagnant in 2011 since the category generally is geared toward new installations due to gas and venting replacements. However, Eternal’s unique design excludes the company from this short-term challenge. In fact, Grand Hall has seen a steady increase in sales and reached 49% of 2010 sales in the first three months of 2011. Long term, Grand Hall expects the category to continue to grow due to the Department of Energy’s renewed focus on energy efficiency in water heating. Also, as the economy improves, people will address more latent issues in their home or business and upgrade their water heaters.

indoor models of the new Prestige Series Condensing tankless water heater are shown here. Using condensing technology, these units offer a .94 EF.
Company History: Founded in 1925 by brothers Richard and Donald Rheem in Emeryville, Calif., Rheem began manufacturing water heaters, boilers and tanks in 1930, and later added gas furnaces and winter air conditioners to its portfolio in 1947. Today, Rheem is the only manufacturer in North America producing both HVAC and water heating solutions. This uniquely enables the company to leverage efficiencies from its water heating and HVAC divisions to create energy efficient, integrated home comfort systems. Company News: In the fall, Rheem will introduce the
second-generation Hybrid Electric Water Heater. This product will feature the hybrid industry’s first color touchscreen LCD display, which will give homeowners greater insight into the home’s water heating energy usage. The product also includes three user-friendly modes of operation: Energy Saver, High Demand (Normal) and Electric Heat Only. Tankless Forecast: Although the short-term outlook for the
market is slow, the long-term viability of the market is strong. Over time, Rheem expects the tankless market to continue to grow, due to an increase in gas water heater efficiency requirements. Tankless FAQ: Do dielectric unions need to be used during the
installation of a tankless gas water heater? No. Unions are designed to prevent electrolysis between
two dissimilar metals, such as a steel water tank and copper plumbing. This is not an issue with tankless water heaters and copper plumbing due to the copper heat exchanger.

Rinnai’s unique condensing design incorporates two innovative heat exchangers to achieve optimum heating value from every cubic foot of natural gas or propane. The stainless steel system recaptures residual heat from flue gases to pre- heat incoming ground water, which then circulates to the primary copper heat exchanger.
Company History: Rinnai Corporation is the world’s largest manufacturer of gas appliances. Established in 1920 as a manufacturer of pressurized oil cooking stoves, Rinnai has expanded its product portfolio to include a wide range of residential and commercial gas appliances for efficiently heating water, air and food. Specifically, this includes continuous flow tankless water heaters, highly sophisticated ductless direct vent furnaces, vent-free heaters, kitchen appliances such as tabletop stoves, ranges and ovens, and dish washers and dryers. Rinnai products are known throughout the world for their superior quality and safety, modulating gas valve technology and sophisticated thermostatic control systems. The company built its reputation upon its achievements in technological innovation and manufacturing efficiency and is now one of the largest companies in Japan. Company News: Rinnai’s new branded valve kit is automatically packaged with all Rinnai tankless units (except the R98HPi/e large
Btu units), simplifying the installation and maintenance of Rinnai products for installers. Rinnai customers and installers now have the option to extend the labor warranty of their tankless water heater by registering the unit
with Rinnai within 30 days of installation. Tankless FAQ: Can you use Rinnai tankless water heaters with a recirculation system? Yes. If you use an on-demand type of system, the warranty for Rinnai’s condensing and non-condensing units remains unaffected.
However, if you use a continuous recirculation system that runs directly through the Rinnai tankless unit, the heat exchanger warranty could drop to three years depending on the model. Please consult the manual for additional requirements and guidelines regarding recirculation to ensure the best fit for your application, and be sure to check with the pump manufacturer to see if they have models specifically designed to work with tankless water heaters.
