The Pennco Series 15B series boilers are standard efficiency home hot water boilers. They are use with hot water radiators, baseboard (heaters) and all kind of radiant heating applications. The Pennco 15B series has been designed with features making it the ideal home heating solution. It feautres an advanced heat exchanger design for durablity and greater heat output the 15B series can achieve fuel efficiencies up to 82% AFUE. With its compact design and low profile draft hood and top supply piping connections allow for easier installation. The pilot is mounted to the front of the burner base for easy maintenance.
