Coal Boilers


The S130 model is perfect for most residential homes. It comes standard with direct-drive (vs. belt-drive) fan. Auto-feed options are available.

Designed to burn Pea or Buckwheat-sized Anthracite coal, each Coal Gun unit ensures minimal labor, nominal expense, maximum fuel efficiency, and marathon burn-time.

The Coal Gun is nearly 100% automated. You can be confident that your boiler is burning at optimum efficiency, without having to make ongoing adjustments. Our signature Thermo Ash-Monitoring Control System automatically regulates burn rate and air intake, ensuring that every ounce of coal yields its fullest heat potential. This technology makes it possible for the fire to burn for days at a time, even during low-use periods.

Operation requires only three simple steps…

Add coal, Remove ash, Repeat every 2–7 days (depending on demand)

The most cost-effective stoker boiler on the market, the Coal Gun saves users up to 70% off their heating costs with conventional oil, gas, or electric systems.

Though designed primarily for use with hydronic boiler systems, the Coal Gun can be adapted to work with forced hot air systems or steam heating applications.

Coal Gun boiler units are made to be the last boiler you’ll ever buy, and require only minimal seasonal maintenance. Built for lifetime durability, many of our units are into their fourth decade of operation.

In addition to the standard 20 year warranty on the full unit, the burn grate in every Coal Gun is covered by an additional lifetime warranty.

Belt Drive Option for Induction Fan

A belt driven induction fan is included as standard on all Coal Gun boilers, except for the S130. The S130 comes standard with a direct-drive induction fan, where the fan motor is mounted directly to the fan cover plate. You can see this on the left-hand side of the image above. The motor shaft extends through this plate, the heat shield and abrasion shield, and the fan is mounted directly to the shaft.

For S130 Coal Guns operating in high demand, the belt drive option serves to isolate the fan motor from the boiler heat.

Auger Loading

The Coal Gun can be enhanced with an auger add-on that eliminates the need to manually fill the hopper. This is especially important on the large models (S500, S1000), as a higher demand for heat requires more regular filling. Auger add-ons have both automatic and manual settings for maintaining coal reserves.

4″ or 6″ Diameter

Your choice of diameter will depend on load size. Auger length can be customized per requirements.

Pulley-Drive or Belt-Drive

The drive method of your auger will be dictated by load size and application. Pulley-driven augers work in scenarios where there is little change in elevation between coal bin and hopper. Belt-driven augers are preferred in situations where elevation varies.

Auger Inlet Guard

An auger inlet guard provides added safety. The guard’s sturdy mesh screen prevents unwanted objects from contacting the auger screw.

ASME Certification

The ASME Certification guarantees the steel grade and weld quality of the boiler water jacket. Each ASME Certified water jacket has been pressure tested to 60 PSI, and includes a 30 PSI release valve.

UL Safety Certification

The UL Safety Certification guarantees all electrical components and electrical engineering used in the design and construction of each unit.
