The Pennco 15B-K series boilers offers phenomenal value for those looking for a price-conscious, reliable, cast iron hot water boiler.  Newly designed, the 15B-K series has an increased efficiency rating (84%) and allows for left or right piping installation.  The boiler includes an internal Low Water Cut-Off to protect from dangerous low water conditions and the burner tray is completely removable allowing for easy service.  A low profile draft diverter hood reduces installation height by up to 30″.
