Energy efficient, using readily available resources, this series of Indoor Coal Boilers is an economical way to heat, making it the number one choice for many consumers who need a non pressurized indoor boiler. Our indoor models burn 30% - 50% less than the competition.
The Indoor Shaker Grate Series is available in three models, all equipped with shaker grates. The shaker grates make it easy to burn coal evenly. With capabilities to heat multiple buildings, these three models range from 2,000 square feet to 10,000 square feet.
They are designed to be located inside garages, shops and barns, not for primary residences. The indoor coal boiler design is a great way to heat the area in which it s installed and has the capability to heat multiple buildings.
For the best corrosion resistance and heat transfer possible, our Crown Royal firebox and outer drum is a round design constructed out of 409 Titanium Enhanced Stainless Steel. The shaker grate and ash pan design was purposefully developed for quick and easy cleaning. The introduction of combustion air under the grates gives a hotter and cleaner burn, while additional air is injected from above the fire, inside the firebox, reducing gases and heat loss up the chimney, producing a cleaner burn that uses less fuel.
