The Series X-2 boiler from U.S. Boiler Co. is a full-featured, gas-fired, cast iron boiler that offers reliability at a value price, the company says. At 84% AFUE, the X-2 is available in seven sizes from 70 to 280 MBH. Design of the American-made, cast iron heat exchanger promotes turbulent water flow for efficient heat transfer. Integrated boiler controls are concealed inside the jacket, and a free additional pump relay is included. The integral LWCO option requires no piping. Industry standard tapping locations and a low-profile flueway provide easy, direct replacement in retrofit applications. A limited lifetime warranty is included.
