The Fulton Difference

Fulton FB-A furnace’s unique “pipe within a pipe” structure sets us apart in the industry. The ingeniously top-mounted burner propels a spiraling, cyclonic flame through the central chamber, ensuring a thorough and even distribution of heat. As the hot gases ascend in the secondary flue passage, they interact with strategically placed heat convection fins. These fins expertly transfer residual heat to the water vessel’s exterior, achieving unparalleled uniform heating. This meticulous design not only enhances efficiency but also significantly extends the lifespan of the pressure vessel, embodying our commitment to excellence and durability.
