VF2500 Hot Air Furnace

Select Warranty

Our Coal Stoker Hot Air Furnaces are a turn-key solution for lowering heating costs.

These units connect directly to your forced air ductwork like a standard furnace. But instead of costly oil, propane, or electricity, our Coal Stoker units burn rice coal with incredible efficiency. Fuel oil backup is an optional add-on.

Intuitive user controls, a temperature-controlled feed rate, a 250-lb large coal hopper, and extended burn time technology make for a relatively automated heating solution.

Oil Backup

The VF2500 can be fitted with a backup fuel option. The F5 Riello burner mounts on the access door and fires into the firebox making a very efficient back up fuel source.

Note: adding the oil backup option voids the standard UL certification.
