These units connect directly to your ductwork and interface with your thermostat like a standard furnace. But instead of costly oil, propane, or electricity, our Stoker units burn rice coal with incredible efficiency. Fuel oil backup is an optional add-on…
Intuitive user controls, temperature-controlled feed rate, large coal hopper, and extended burn time technology make for a relatively automated heating solution.

The Multi-Fuel boiler can be fitted with a backup fuel option. This option requires a dedicated firing chamber for the boiler that must be built in to the vessel during manufacturing. This chamber is water jacketed for its entire length for excellent heat exchange and efficiency.
Note: adding the oil backup option voids the standard UL certification.
For #2 fuel oil, the backup system can function in an automatic switch-over scenario, with fuel oil taking over when the boiler has exhausted its coal fuel. For other fuels, such as natural gas or propane, switch-over is manual only.
