Indoor Coal Boilers

The Coal Gun is almost 100% automated. You can be sure that your boiler is heating up at maximum effectiveness, without having to make alterations all season. Our trademark Thermo Ash-Regulating Control System instantly monitors the burn rate, making sure that each ounce of coal yields its maximum heat capacity. For more sizes…Click Here

Engineered to ignite Pea-sized Anthracite coal, every Coal Gun unit ensures the least work, nominal expense, optimum fuel efficiency, and maximun burn-time.

The operation involves three easy steps…

Add coal, dump ash, Redo 2–7 days (varying on demand)

The highest cash-efficient stoker boiler on the market, the Coal Gun cuts down on nearly 70% of our customer’s heating expenses with traditional oil, gas, or electric systems.

Though engineered mainly for utilization with hydronic boiler systems, the Coal Gun can operate with forced hot air systems or steam heating systems.

Coal Gun boilers are created to be the final boiler you’ll ever purchase and need only minimal seasonal upkeep. Constructed for lifetime durability, many of our units are into their fourth decade of heating.

In addition to the typical 20-year guarantee on the vessel, the burn grate in the S130 and s260 Coal Guns is protected by a lifetime guarantee.

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 cover.

Belt Drive Option for Induction Fan

A belt-driven induction fan is included as standard on every Coal Gun boiler, with the exception of the S130. The S130 comes standard with a direct-drive induction fan, where the fan is mounted directly to the motor shaft.

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

Automatic or Manual Oil Back-Up

The S130 and S260 are able of being fixed with an oil burner. The burner is engineered to burn into the Coal Gun’s heat exchanger.

This is a great option that eliminates a second appliance and all the plumbing that comes with it. The Oil Back-up for the S130 and S260 comes as a manual switch-over. With this option, if you ever run out of coal or plan a long holiday you will be prepared!

Domestic Coil

This Domestic Coil shows 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 fixture given on the boiler for this reason

Extended Base

The Extended Base enhancement for the S130 provides it with an extra-large ash pan that is 3x bigger than the typical ash pan, which significantly lengthens the time period between emptying. It also makes the ash pan attainable to front-end loaders making discarding the ash hands-free.

Warnock Hersey Certification

WH certification is accessible on every Coal Gun boiler for an extra fee. This certification guarantees that the boiler abides by UL 2523 Standards. Some insurance companies may need this certification and it is the liability of the homeowner to make certain the requirement for a WH certification on any boiler bought.

Auger Loading

The Coal Gun can be improved with an auger add-on that removes the need to fill the hopper manually. Auger add-ons have both manual and automatic settings for upkeeping coal reserves.

4″ or 6″ Diameter

Your selection of diameter will vary on load size and cleanliness of coal. If your coal generally has debris, like wood chunks, a 6″ auger would be suggested. Auger length can be modified to suit per demand.

Auger Inlet Guard

An auger inlet guard gives extra safety. The guard acts as a stand for the bottom end of the auger keeping the screw off the ground. It is 304 stainless steel which will never rust or rot out.

ASME Certification

The ASME Certification secures the steel quality and weld standard of the boiler water jacket. Every ASME Accredited water jacket has been pressure tested to 60 PSI and comes with a 30 PSI release valve.

Low Water Cutoff

A Low Water Cutoff senses the water level in the boiler’s vessel and will close the unit down if the water level falls to a dangerous level. It is available in both manual and automatic reset.

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.

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. With this option if you ever run out of coal or plan an extended vacation you will be ready!

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.

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.
