Indoor Wood Boilers for Heat Production
A wood boiler is an indoor heating device that burns firewood to produce heat for your building. Firewood burns in a precisely controlled chamber, which produces heat. This heat is transferred to your domestic hot water or into your building to create a warm and comfortable environment.
Tarm Biomass customers choose wood boilers for their heating needs because they:
Save money on heating costs compared to other heating systems.
Can potentially earn you a federal or state rebate.
Are an environmentally friendly substitute for fossil fuels.
Can benefit your local economy.
Have a near-neutral impact on atmospheric carbon and manage your carbon footprint.
Help you achieve energy independence.
With our wood boilers, maintenance is simple and infrequent. Regular cleaning and repairs when necessary will keep your boiler in great shape for many different seasons. We will happily point you in the right direction of a local maintenance and quality service provider for your boiler.
High-Efficiency Wood Boilers
Fröling boilers are manufactured by the leading name in the industry and are safety tested and listed. One of our most efficient and popular indoor wood boilers is the Fröling S3 Turbo. The S3 Turbo sets the standard for wood boilers by using state of the art combustion controls and other advanced features to capture heat energy from firewood. S3 Turbo wood boilers are simple to operate and maintain in both hot water and hot air heating applications.
This indoor wood boiler model offers features like:
- Smoke extraction: The boiler has a smoke hood built into it, eliminating smoke during reloading.
- Easy-start ignition door: The lighting door makes it easy to ignite a flame. It uses the induced draft system to ignite the fire quickly, requiring no switches or levers.
- External heat exchange cleaning: The S3 Turbo has a built-in heat exchange system that reduces or eliminates hand brushing, promoting efficiency. Ash can be removed through a rear access door.
- Lambda-controlled combustion: The lambda-controlled downdraft technology monitors excess oxygen and adjusts the secondary and primary combustion air. This process optimizes combustion and gives the boiler a variable output matching your heating needs.
- Variable speed-induced draft: The S3 Turbo fan speeds ignition and captures the smoke from the ignition process. This feature reduces leaking smoke around the doors while promoting output control.
We offer two models of the Fröling S3 Turbo Wood Gasification Boiler. The 30 model generates 96,000 British thermal units per hour (Btu/hr), and the 50 model emits 164,000 Btu/hr.
Fuel for the Indoor Wood Boiler
Wood is the most widely available and least expensive biomass fuel available. Burning firewood produced on one’s own land has the lowest carbon impact of all forms of wood-burning and therefore can be considered the most sustainable form of wood burning. Boiler owners who produce their own firewood as a byproduct of managing their woodlots will also realize the greatest savings and cost benefits.
Firewood is normally sold in units called cords. A cord of wood is a neat stack measuring 4 feet wide by 4 feet high and 8 feet long. The heat content of a cord will vary depending on the species of wood. A cord of mixed softwood will have a heat value of 17 or 18 million BTU, and a cord of mixed hardwood will have a heat value of 20 to 29 million BTU.
By way of comparison, a gallon of No. 2 fuel oil has a heat value of 140,000 BTU per gallon, and propane has 93,000 BTU per gallon. Please use our fuel cost comparison tool to calculate the relative fuel costs in your area.
You should thoroughly dry firewood before using it in wood boilers. Firewood moisture content impacts the efficiency of your wood boiler, meaning the lower the water content, the better. At a minimum, we recommend drying firewood every six months to a year to ensure the moisture is low enough to burn efficiently.
Questions Many People Ask About Wood-Fired Boilers
The basic questions many people ask about wood-fired boilers include:
A basic wood boiler consists of a primary and secondary chamber, an ash box, water supply, and return connections, and a control system. The operator loads firewood into the primary chamber, where they then ignite the wood and allow it to start burning. As the wood begins to burn, the gases released from combustion pull into the secondary chamber, where they continue to burn to maximize heat output. Heat transfer tubes exchange heat to the water pipes to create hot water.
Since almost all gases and tars burn in the chamber, harmful smoke is significantly diminished. Wood boilers can combine with your existing furnace as a backup system or serve as your primary heat source year-round.
Wood boilers can connect to or replace existing heating furnaces and boilers with automatic controls.
