The Keystoker Koker Lite is a hot air automatic coal furnace that outputs a lot of heat to keep your home warm throughout the winter (up to 105,000 BTUs). The Koker Lite utilizes a few patented designs from Keystoker to achieve a super efficient and clean burning combustion that keeps your home warm while minimizing your carbon footprint.
One of the patented Keystoker designs this coal furnace features is the deep firebox, which allows the fire to burn hotter. The hotter fire burns the anthracite coal more efficiently and cleanly, while emitting more heat to be used throughout your home. The other patented design this coal burning furnace also features is a built in heat exchanger that cools the exhaust air system, forcing the heated gases to the bottom of the furnace, and then back up through two 4" pipes that allow the convection blower to garner even more heat. This automatic coal furnace uses an included Honeywell wall thermostat which has the furnace running just right to keep your home at the temperature you set. With a choice in direct venting, as well as using top or rear venting, you have greater flexibility in how the Koker Lite is installed in your home.
To keep this coal furnace burning as clean as possible, clean burning anthracite coal should be used for fuel, which allows you to keep your impact on the environment minimal as well as saving you some money compared to furnaces that use other fuels (like oil, or gas). And with this great clean coal furnace backed by a 5-year warranty from Keystoker, you can enjoy your American made product for years to come.
