Outdoor Wood Furnaces

Central Boiler outdoor furnaces burn wood to heat water that is circulated through insulated pipes. Water can transfer its heat by direct circulation or by moving through one or more heat exchangers, or both. Of course, your situation is unique, so it’s important you talk to a Central Boiler dealer to make sure you select the right model for your application.

Cruise Control for the Furnace

STAY CONNECTED! More than just a controller, the FireStar Combustion Controller features built-in wireless connectivity, giving you the ability to communicate with the furnace without additional equipment or cumbersome ethernet cables.

 

The FireStar® combustion "cruise" controller takes all the worry and guesswork out of wood heating. It constantly throttles the air to find the optimal burn for any kind of firewood, meaning you can “load it and forget it.” FireStar constantly monitors how the wood is burning and adds air where and when it’s needed for the cleanest, most efficient combustion. You can even see how it’s operating in real time on your smartphone or set up notifications so you’ll know when it’s time to add wood.

Durability

The titanium-enhanced stainless steel firebox ensures zero corrosion inside the firebox and can last a lifetime. With features like Reserve Mode and the Burning Time Monitor, burn any kind of firewood.
