Indoor Coal Boilers

The Coal Guns are coal stoker boilers. Our coal boilers are made in southern Pennsylvania. We use thick high-quality steel that gives you a lifetime of service. The Coal Gun uses our trademark Thermo Ash-Regulating Control System. This system constantly monitors the burn rate, to make sure each ounce of coal yields its maximum heat capacity. Because we monitor the ash temperature your coal boiler will efficiently burn coal all year. This eliminates the need to make alterations to the auger/grate feed rate or the combustion fan speed.

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

The operation involves three easy steps…

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

The Coal Gun cuts down on nearly 70% of our customer’s heating expenses with traditional oil, gas, or electric systems.

Though mainly used with hydronic heating systems. The Coal Gun can also be used with forced hot air systems or steam heating systems.

Coal Gun boilers are created to be the last coal boiler you ever need to purchase. All in all, they are also easy to maintain, as they only need yearly cleaning. Our coal boilers are made by expert craftsmen and are over-engineered for lifetime durability. This is why many of our units are into their fourth decade of heating.

Coal Guns come with an incredible 20-year guarantee on the vessel. The grate is guaranteed in the S130 and s260 Coal Guns by a full lifetime guarantee.

Standard equipment includes an insulated boiler jacket, 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 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!

100-002-domestic-coil-2

Domestic Coil

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

Extended Base

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.

intertek-warnock-hersey-us

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.

Auger Loading

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.

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.
