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.
Standard equipment includes an insulated boiler jacket, totally enclosed motor and drive systems, primary and backup aquastat thermostats, thermo ash-monitoring control, pressure relief valve, ash pan and square hopper with lid.

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.
Automatic or Manual Oil Back-up
The S130 is capable of being fitted with an oil burner. The burner is designed to fire into the Coal Gun’s efficient heat exchanger. This eliminates the need of a second appliance and all the plumbing that comes with it. The Oil Back-up for the S130 comes standard as a manual switch-over but an automatic switch-over is available. With this option if you ever run out of coal or plan an extended vacation you will be ready!
This Domestic Coil features a 100° F rise at 5 gallons per minute, 50° water inlet temperature and 65 PSI water pressure. It is threaded into a 4 IN NPT threaded fitting provided on the boiler for this purpose
The Extended Base upgrade for the S130 gives it an extra-large ash pan that is 3x bigger than the standard ash pan, which greatly extends the time period between emptying. It also makes the ash pan accessible to front-end loaders making dumping the ash hands-free.
Warnock Hersey Certification
WH certification is available on all Coal Gun boilers for an additional charge. This certification assures that the boiler complies to UL 2523 Standards. Some insurance companies may require this certification and it is the responsibility of the homeowner to determine the need for a WH certification on any boiler purchased.
The Coal Gun can be enhanced with an auger add-on that eliminates the need to manually fill the hopper. 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 and cleanliness of coal. If your coal typically has debris, like wood chunks, a 6″ auger would be recommended. Auger length can be customized per requirements.
Auger Inlet Guard
An auger inlet guard provides added safety. The guard’s sturdy mesh screen prevents unwanted objects from contacting the auger screw.
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.
Low Water Cutoff
A Low Water Cutoff senses the water level in the boiler’s vessel and will shut the unit down if the water level drops to an unsafe level. Available with automatic reset or manual reset.
