The H. B. Smith Company, a true pioneer in the heating industry as we know it today, was founded in the mid-1850's by two brothers, Henry B. and Edwin Smith. Originally manufacturing fences and other ornate iron work, the Smith brothers' manufacturing expertise turned to cast-iron heating products in 1859 when they formed an association with inventor, Samuel Gold and commenced manufacturing his patented "Gold" boiler/radiator products.
As the central heating industry grew, so did The H. B. Smith Company; and by 1879 the company was also manufacturing the "Mills" boiler patented by inventor John Mills. A century and a half later, The H. B. Smith Company continues to manufacture a broad line of quality cast-iron boilers for both residential and commercial, industrial applications, including several models of "Mills" design.
