What does the FireStar Combustion Controller do?

The FireStar Combustion Controller optimizes the gasification process which results in burning up to 60% less wood than with traditional methods. The controller also has E-Link technology which allows you to connect your outdoor furnace to the internet where you can monitor it from anywhere in the world.

You can have the controller send you a reminder on your smartphone when the load gets down to 50% or 25% of the wood left. If you don’t fill the furnace before the wood is gone, it will activate the Reserve Mode to keep enough wood so you will not have to start a new fire when you reload.

The FireStar Combustion Controller monitors all functions of the furnace and optimizes the gasification process automatically.

Working much like a car's engine control unit (ECU), the FireStar optimizes furnace performance by using sensors to decide how to control and independently adjust the primary and/or secondary air. By adding the right amount of air in the right place at the right time, the controller is able to optimize the gasification process to achieve the cleanest and most efficient burn possible.

The FireStar Combustion Controller is loaded with features designed to make operating your Central Boiler outdoor furnace easier and more convenient than ever before. If you want to learn how FireStar works on a Classic Edge Titanium HDX outdoor wood furnace, be sure to check out the video.
