MEET THE WORKHORSE: THE HOSS FL400.

The FL400 Front Loading Furnace is our oldest and most trusted model for residential and smaller commercial applications; and a closer look shows you what goes into this HOSS.

▪ ½-INCH-THICK STEEL FIREBOX
Heavy steel at the heart of the furnace, with a firebox measuring 48” deep × 30” wide × 40” tall.

▪30"x40" MASSIVE DOOR
Ease of loading and maintenance.

▪ 450,000 BTU
Serious heating capability for property owners looking to put biomass heat to work.

▪ 340-GALLON WATER CAPACITY
The FL400 heats water that circulates through a meticulously designed heating system. The flue is fully encapsulated by water. It begins at the front of the furnace and exits at the back, allowing for substantial heat transfer. Inside the firebox is a half-inch-thick heat-transfer shelf that concentrates all the gases before they reach the flue, creating a rich environment to burn off the gases and transfer that heat into the water jacket before the exhaust leaves the water-surrounded flue.

▪ MULTIPLE-LOOP CAPABILITY
One standard set of 2” ports can serve five 1” loops, giving you options for distributing heat to different spaces. (Thicker pipe walls)

▪ FORCED DRAFT & INDUSTRIAL GRATES
Forced draft supplies combustion air to the fire, while industrial grates support the fuel bed.

▪ PRACTICAL DETAILS
Wi-Fi aquastat along with an additional front-mounted mechanical thermometer puts water-temperature readings in plain sight.

▪ OVERALL DIMENSIONS
60” wide × 77” tall × 89” long.

Heavy steel. Straightforward design. A furnace built to earn its place on your property.
