ORLANDO, Fla. - Lochinvar has announced the expansion of its Power-Fin boiler line. These new boilers offer an input capacity from 500,000 to 1,300,000 Btuh, but require just 4.6 square feet of floor space. They also require zero clearance on each side to ensure a truly minimal footprint, says the company.

The Power-Fin is available in two firing configurations: on/off or full modulation. The on/off model is designed for replacement or retrofit applications where an existing Category I vent is already installed. The full modulation model provides maximum energy efficiency. It reduces heat output in 1 percent increments as demand drops, which optimizes fuel use, the company says. These units have a 4:1 turndown, meaning their peak output is four times as high as the minimum stable firing rate.
