Easy to Operate

FireStar Combustion Controller


Furnace operation couldn’t be easier. The FireStar® combustion controller 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.

Top Performance

Use up to 60% less wood compared to other methods of wood heating and deliver more heat to your home. All Central Boiler furnaces are engineered to minimize heat loss, from the construction of the firebox door, panels and pump access area to the airtight, waterproof spray-on urethane foam insulation. The larger firebox allows for longer burn times, saving you even more time.

Classic Edge HDX models are EPA-certified clean-burning and are among the most efficient, best ways available to burn wood.

Easy to Maintain

Maintenance is minimal (usually only requiring a few minutes a week) thanks to the rear hinged door and patented vertical heat exchanger. You'll appreciate the smart features of the Classic Edge HDX when it comes to ash removal, where access to both the front and back of the furnace is quick and easy.
