FHS has provided wood heating systems to  a range of businesses, including hardware stores, B&Bs, inns, senior living centers, schools, farms and co-housing communities. Our systems heat living and working spaces ranging from 1,200 to 40,000 square feet.   Historically these systems amortize their costs in between five and eight years .  In addition to their fuel cost savings, many businesses have have installed wood fired systems in order to keep their fuel dollars in the local community and to have a secure sustainable future source of heating fuel.

Hydronic Design

Heating with wood begins with thoughtful design and a whole-systems approach, starting with where the wood is sourced and how it is handled, to determining your business’s heat loads and firing frequency. We ask the right questions from the beginning to help design a heating system that works with your business or meets your industry needs. Good design saves money on installation and operating costs and ensures that your heating system is optimized and will run well for years to come.

GARN WHS

The GARN WHS is easily integrated into both existing buildings and new construction. The boiler can provide heat through a number of systems — radiant floors, hot water baseboards, panel radiators or forced air furnaces. It can also provide your domestic hot water.

The cutting-edge technology of a GARN WHS is simple, efficient and durable. With patented, two-stage wood gasification technology, the GARN system is virtually smokeless — which means clean air for everyone, and a comfortable experience for users. The steel fuel chamber is easy to load and the door is always cool to touch. The GARN WHS is simple and is easy to operate and maintain because it’s made of just three moving parts — the handle, door and blower. It is built to last indefinitely.

Wood Sources

GARN boilers can use any number of fuel sources: cordwood, slab wood, scrap wood, etc. A number of our businesses we work with have turned previous waste streams into a valuable resource that provides their business with heat, reducing operating expenses and increasing profits.  Over a winter, a GARN WHS uses about half the wood of a conventional wood boiler.

Thermal Storage

The key to the GARN system is thermal storage, meaning that the heat produced in the combustion chamber (where you add your wood) is stored in a tank of water. With a GARN boiler, a fire doesn’t have to be burning constantly. In between firings, the insulated thermal storage tank stores heat that is available whenever your system has a demand. GARN boiler tanks range in size from 980 gallons to 3,200 gallons, to suit a range of spaces. When you turn a thermostat up, a pump draws hot water out of the thermal storage tank and into the heating system in your home, business or greenhouse.

Clean Air

While wood stoves are a traditional and comforting source of heat, they are also polluting, as are many wood boilers. When you close the dampers on a wood stove to reduce the heat and slow down the burn rate, you also create smoke, soot, fly ash, and creosote.

The GARN WHS is virtually smokeless as it burns the wood quickly and cleanly with its two-stage wood gasification technology. The smoke that is produced in a GARN boiler not only doesn’t pollute the air, it is capitalized as a secondary fuel. A well-insulated combustion chamber needs steady airflow to achieve high-temperature combustion. A fan on the GARN system sucks air into the combustion chamber, where it is split into a top stream and a bottom stream. The bottom stream passes through the burning logs, engendering a very hot fire. The top stream skims the top of the combustion chamber, gathering with it the volatile gases given off by the burning logs. This top stream enters a small chamber in the back where it is lit and burned to produce a second fire and a second heat source.

If you would like to reduce your reliance on fossil fuels and/or lower your heating bills, FHS can help you design and install a wood-fired hydronic heating system that fits your business’ size and needs. Please contact us by phone or email and fill out our Hydronic Heating Design Form. We look forward to working from you.
