Heizomat GMBH from Germany
Heizomat has been building high quality boilers in Bavaria since 1983. Heizomat boilers come in a wide range of sizes and burn a variety of biomass fuels, from pellets to wood chips, to other difficult fuels such as chopped straw, miscanthus, and switchgrass. Heizomat’s modular and pre-engineered feed systems do not require on-site fabrication thus reducing installation costs. They include automatic feed from a custom fuel bin, automatic lighting, burning, modulation, and cleaning of heating surfaces, and de-ashing to an ash can or dumpster. Service and maintenance is typically performed two or three times per year.
Feed systems are available up to a16 foot diameter chip bin, as well as extended augers for fuel transfer from remote fuel storage. Boiler sizes are available in the US from 680,000 btu to 3.8 Million BTU for hot water distribution (not steam).
Typically, wood chip and biomass heating systems become economical at heat loads of 500,000 BTU, serving 4,000 square feet of greenhouses or 10,000 square feet of manufacturing, shop space, or warehousing, and beyond.
heatmaster SS B-500 and B-1000 from canada
Heatmaster B-Series boilers are a relatively new entry to the US biomass market and offer an economical option for the 500,000 and 1 Million BTU size class. Their 8 foot and 15 foot diameter fuel bin options allow great flexibility in fuel handling. Fuel options include wood chips, agricultural screenings, and coal.
A B-500 will heat up to 25,000 square feet of normal heated space, or 6,000 square feet of greenhouse*. A B-1000 will heat up to 50,000 square feet of warehouse or manufacturing, and 12,000 square feet of greenhouse*.
*More if a backup fuel is available to take peak heat loads.
