The Coal Gun uses Pennsylvania’s domestically mined anthracite coal and produces heat not only for a whole residence but for your domestic hot water as well. The best part is that is does all that for about 70% less cost than electric and nearly 50% less cost than traditional oil or gas systems.
The outdoor housing can be customized to complement the color of the user’s residence’s exterior wall or outbuilding. Call today for more information!

The bottom line is that our high-quality standards will save you both time and money in your heating application.
How It Functions…
From the giant hopper, pea-sized anthracite coal is gravity fed into the coal pot. A draft fan pulls the air through the fire enhancing the combustion of the coal. The hot exhaust enters the heat exchanger, the Swirl Chamber. In the Swirl Chamber, the hot exhaust and fly ash are spun around in the chamber. This allows more heat released into the water and the swirling fly ash scrubs the walls allowing maximum efficiency all season. The cooled exhaust and the fly ash now enter the cyclone ash separator where the rest of the ash is deposited in the ash pan. Anthracite coal does not cause creosote or release any smoke!
The Consumption of Coal…
Several factors can affect the quantity of coal used such as your climate, and building construction. Because of its high efficiency, however, Coal Guns utilizes less coal than other units on the market and will greatly lessen your yearly heating costs.
Thermo Ash-Monitoring Control…
Every Coal Gun boiler uses our Thermo Ash-Monitoring Control which gives optimum utilization of your fuel. The Thermo Ash-Monitoring Control instantly regulates the temperature of the ash. From the temperature of the ashes, we know when to shake the ashes into the pan. This allows the Coal Gun to thoroughly burn every pound of coal.
The Thermo Ash-Monitoring Control very rarely needs adjusting to get more or less BTU/hr when moving from the mild season to dead of winter. The boiler automatically adjusts to the needed output throughout the entire burn season (a minimal on-site alteration may be required when the boiler is first installed). With the Thermo Ash-Monitoring controlled grate, it is likely for the fire to remain burning for days during periods of little to no use.
