HY-C Commercial Wood Heating Appliances

From left to right: the Ignite Tech HD90X Outdoor Wood Furnace, the GARN wood boiler, and the Ignite Tech HD80 Indoor Wood Furnace.

The wood heating appliances covered in this article are approved for commercial use only and may not be used to heat residential buildings in the United States. Common commercial applications include greenhouses, agricultural businesses, construction companies, fabricators, landscaping businesses, tree service companies, etc.

If you operate a business in a relatively remote, rural area, heating your building can be costly. Lack of access to natural gas, oil, or propane makes these resources very expensive, significantly driving up the price of keeping you and your employees warm.

There is another option, though: burning wood. Heating your business with cordwood fuel is especially viable if you have access to free or low-cost firewood. The savings mean the unit can pay for itself over time, allowing you to invest that money back into your company.

At HY-C, we manufacture three commercial wood heating units

  1. The GARN GN2000 Wood Boiler
  2. The Ignite Tech HD80 Indoor Wood Furnace
  3. The Ignite Tech HD90 Outdoor Wood Furnace

In this guide, we’re going to take a closer look at each one of them. We’ll cover the specifications of each unit, how much each one costs, the heating area each unit covers, and much more.

By the time you’re finished here, you’ll know the ins and outs of each of these units, and you’ll be able to decide whether or not a commercial wood heating appliance is right for you and your business.

The GARN GN2000 Wood Boiler

  • Unit Type: Wood boiler
  • Heating Area: 10,000 square feet
  • Price: Up to $30,000

The GARN GN2000 is a boiler powered by wood fuel. It has a 17.4-cubic-feet firebox capacity and a tank capacity of 1,830 gallons of water.

The unit works by combining two principles: gasification and thermal storage. Its water tank is filled to capacity, and a full load of firewood is placed in the firebox. That firewood is then batch-burned at high temperatures, warming the water in the tank.

That hot water acts as the unit’s thermal storage, keeping a steady supply of heat available throughout the day. The heat can be delivered to your business by three different methods:

  1. Baseboard heating
  2. Radiant floor heating
  3. Forced air heating

The heat delivery system you use depends on the construction of your building, how it’s insulated, the climate in your area, and several other factors. A hydronic heating contractor can help you decide which system is best for you.

Made in the USA, the GARN GN2000 wood boiler is capable of heating up to 10,000 square feet. Depending on the size of your business, it’s not uncommon to use two or more units in conjunction with one another. A single unit can deliver 200,000 BTUs of heat per hour.

The GARN boiler burns incredibly cleanly, emitting just 1.69 grams of particulates per hour. It runs efficiently, too, with an ASTM-tested efficiency of 82%. A GN2000 costs around $30,000 (excluding the cost of installation which varies widely based on your building and location).

The GARN GN2000 wood boiler is approved for commercial use only in the United States. It may not be installed in a residential setting (though we do manufacture EPA-approved residential wood furnaces). It is approved for residential use in Canada.

The Ignite Tech HD80 Indoor Wood Furnace

  • Unit Type: Wood burning furnace
  • Heating Area: 3,000 square feet
  • Price: Up to $4,399

The Ignite Tech HD80 is one of two commercial forced-air furnaces in the HY-C catalog. An indoor model, this furnace connects to your building’s ductwork. As the fire burns in the firebox, a distribution blower on the back of the unit pushes warm air through the ducts and into the rest of the building.

The back blower has three settings: 1,200 cubic feet per minute (CFM), 1,500 CFM, and 1,800 CFM to deliver the right amount of heat exactly when you need it. Its 8.2-cubic-feet firebox capacity holds plenty of wood to optimize burn times and minimize reloading throughout the day.

The HD80 is thermostatically controlled. The building’s thermostat connects to a draft blower that blows air directly into the firebox. When the thermostat calls for more heat, the draft blower stokes the fire, causing it to burn hotter and deliver more heat to your workspace.

One of the most convenient features of the unit is its cast iron roller grate. The grate’s bars rotate 360 degrees via a handle on the outside of the unit, allowing you to stoke the fire and filter out ash and soot without having to open the furnace’s door.

The Ignite Tech HD80 is capable of heating 3,000 square feet. It has an MSRP of $4,399, which doesn’t include the cost of installation (i.e., ductwork connection, chimney construction, etc.). It is approved for commercial use only in the United States.

The Ignite Tech HD90X Outdoor Wood Furnace

An Ignite Tech HD90X Outdoor Wood Furnace installed on a concrete slab outside a business. It sits next to a firewood rack full of wood.

  • Unit Type: Wood burning furnace
  • Heating Area: 3,000 square feet
  • Price: Up to $4,999

While the Ignite Tech HD80 is an indoor unit, the HD90X is designed for outdoor installation. It works similarly, utilizing an 1,800 CFM blower motor to blow heat generated within the unit into the building onto which it’s installed.

Like the HD80, the HD90X is thermostatically controlled to increase the efficiency of the heat production and distribution processes. It also comes with pre-wired electrical components that install easily without the need to hire an electrician.

While it doesn’t come with an internal roller grate, it does feature a heat dump system on the top of the unit. In the event of a power outage, a spring-loaded door on the top of the furnace pops open, dissipating the heat in the firebox and preventing damage to the furnace.

The HD90X is capable of heating areas up to 3,000 square feet. Its MSRP is $4,999 for the unit itself (again, excluding the cost of installation and related materials). Like the other units in this guide, the Ignite Tech HD90X is approved for commercial use only.
