The S1000 coal stoker boiler offers the highest BTU output of all the Coal Guns. It is perfect for medium to large commercial buildings and is nearly 100% automated. You can be confident that your boiler is burning at optimum efficiency without having to make ongoing adjustments.
Every Coal Gun is manufactured from the highest-quality materials by highly trained, dedicated technicians. Every unit is tested extensively before it leaves our factory to ensure its adherence to our high-quality standards.
Each Coal Gun comes complete with all controls necessary for operation and safety. Standard equipment includes an insulated boiler jacket, a totally enclosed motor and drive systems, primary and backup aquastat thermostats, thermo ash-monitoring control, pressure relief valve, ash pan (x2), and square hopper with lid. The S1000 also comes with hopper-level controls and is ASME-certified.
Pea or Nut sized anthracite coal is transferred to the coal pot from the hopper.
Fuel Consumption…
The S1000 can use pea or nut sized anthracite coal. The amount of fuel used depends on many factors, including the weather, type of installation, and building construction. Due to its high efficiency, the Coal Gun uses less fuel than other units on the market and will substantially reduce your annual heating costs.

Extended Base
The Extended Base upgrade for the S1000 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
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.
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. 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 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.
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.
