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.
How an Indirect Water Heater Works
Indirect water heaters utilize the power and large heating capacity of a boiler to provide
year-round hot water at low operating costs.
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.
