Burnham Alliance SL™ Indirect-fired Water Heater There can be extensive demands for domestic (potable) hot water in both residential and commercial applications. Hydrastone-lined Alliance SL indirect-fired water heaters meet the needs for domestic hot water with a unique design and uncompromised reliability. HowanIndirectWaterHeaterWorksIndirect water heaters utilize the power and large heating capacity of a boiler to provide year-round hot water at low operating costs. 5 Sizes Available The hydrastone-lining provides a protective barrier between the domestic hot water and the steel tank. This rugged tank desing works well in a wide range of water conditions and operating temperatures. Alliance SL water heaters have a higher recovery rate than typical direct fired or electrically operated water heaters because they utilize the large output from the boiler as the heat source. A Diverse Offering To meet the needs of virtually any residential or commercial application Alliance SL water heaters are available in five sizes: 27, 35, 50, 70 and 119. Whether it is a three-story house or a 30-story apartment building, Burnham has the right size Alliance SL for the job. Benefits of Installing an Alliance SL Easy Installation The coil comes installed and can be easily turned to line up with the boiler and domestic water piping on replacement installations. (The AL119SL coil is shipped separately). Easy Service All connections are located on the top of the tank and all of the controls are located on the front of the tank for easy service and installation. The heat exchanger can be removed without having to drain the tank. (The AL119SL utilizes a side mounted coil). Unique10/2/1 Warranty A 10-year full tank replacement, two-year labor and one year on parts, which include the coil, come with every Alliance SL. An optional lifetime warranty is also available. Hydrastone-lining The concept of stone-lined water tanks is not a new one, and has been proving successful against corrosion for ages. Many of the stone-lined tanks are installed are 25-30 years old. In fact, the New England area has been using stone-lined tanks for years due to their water supply being very acidic and has been devastating to glass lined tanks. What makes the Alliance SL unique is the Hydrastone-lining. This one half inch lining protects the steel tank from the corrosive action of water. When the water first enters the tank, it is absorbed into the Hydrastone-lining permanently. This water loses its oxygen and becomes inert, non-corrosive water which then acts as a protective wall between the hot water and steel tank. This unique process and design makes Alliance SL water heaters a great choice for domestic hot water applications. Unique cold water diffuser to increase output by 20 percent. Hydrastone-lining protects effectively against corrosion. Larger coil diameter and spacing designed and positioned for maximum heating output and minimizes build-up. Top mount removable heat exchanger with double o-ring design for easy installation and service and eliminates the need for welds between the piping and the tank. Two to three inches of polyurethane foam insulation combined with the stone lining resulting in extremely low standby heat loss. Proprietary TPI control accurately controls the output water temperature and helps eliminate tank “overload.” Note: No anode rod required Heavy gauge steel helps increase integrity of the tanks Alliance SL™ The Alliance model AL119SL utilizes a side mounted coil that is supplied separately. 27, 35, 50 & 70 Ratings Maximum Continuous Draw Standby Minimum Boiler Water Pressure Drop Model First Hour Rating at Rating at 135°F Loss Boiler Output Flow Rate through Coil Number 135°F (gal./hr.)
