### Boiler Efficiency - Clayton Industries Boiler and Steam Basics

The efficiency of a process steam boiler/industrial steam boiler is important to a purchase evaluation because the annual cost of fuel can be 2-3 times the installed cost of the equipment. Hence, a difference in efficiency and the resultant difference in fuel cost can offset the difference of installing the product.
