The installation of a wood burning furnace is typically a pretty involved process. It can involve hiring a sheet metal fabricator, an HVAC professional, an electrician, and maybe even a mover to get the furnace to its desired location. And if you’re like most buyers, the thought of a self-installation won’t even cross your mind — many people simply defer to the professionals.

If you’re DIY-inclined, though, and you end up buying one of HY-C’s Fire Chief FC1000E furnaces, you’re in luck: we designed it to be about as self-install-friendly as a wood burning furnace can be. So if you’re interested in installing your FC1000E without professional help, you’re in the right place.

By the time you’re done with this guide, you’ll understand the 9 steps of the Fire Chief FC1000E’s installation process, and you’ll be ready to hook your new wood burning furnace up all on your own — no professional assistance required.

9 Steps of the Fire Chief FC1000E’s Installation Process

Step 1: Place the furnace as close to the chimney as possible

The first step sounds easy: put the furnace where it needs to go. It’s tougher than it sounds, though, as wood burning furnaces are heavy; the FC1000E weighs over 400 pounds, and most wood burning furnaces are installed in basements. Maneuvering the furnace into your house and into place is a delicate process, so do it carefully and thoughtfully (preferably with a dolly).

Installing the chimney flue is critical to ensuring efficient wood burning performance. Note that the connecting pipe from the furnace to the chimney may not have a horizontal run greater than five feet to function properly, so place your furnace accordingly.

It’s also crucial to abide by the FC1000E’s suggested clearance-to-combustibles ranges — the distances from which the furnace must be kept from any flammable materials (like drywall, wood, cardboard boxes, etc.). These distances are as follows:

• Front of the furnace: 48”
• Rear of the furnace: 12”
• Sides of the furnace: 6”

Before moving on to step 2, if you would like to set your furnace on a furnace stand, now’s the time to do it.

Step 2: Attach the distribution blower

The distribution blower is the big, motorized fan that pushes warm air created by the fire in the firebox throughout the rest of your home. Attaching the FC1000E’s distribution blower is fairly straightforward: the furnace comes with angle brackets, nuts, bolts, and mounting screws.

Just attach the angle brackets to either side of the distribution blower with the nuts and bolts, and then secure the distribution blower to the base of the furnace with the mounting screws.

Step 3: Assemble and attach the filter box

An air filter helps to protect the distribution blower and circulate clean air throughout your home. In order to add an air filter, you have to assemble the filter box. The box consists of four panels — a bottom panel, a top panel, and two side panels. Each panel comes with pre-drilled holes and sheet metal screws for easy assembly.

Put the filter box together and attach it to the furnace around the distribution blower. After you’re finished installing your furnace, slide an air filter into the filter box. Do note that the FC1000E does not come with an air filter.

Step 4: Install the draft blower

While the distribution blower is the fan that blows hot air from the furnace into the rest of the home, the draft blower is a smaller fan that blows air directly onto the fire to keep it burning longer and hotter. Installing the draft blower on an FC1000E furnace involves 3 steps.

1. Attach the draft blower

The first step is to use the included hardware to mount the draft blower itself onto the front of the furnace (near the ash pan door).

2. Mount the electrical control center

Next, attach the electrical control center to the filter box. Two important components will connect to the electrical control center: a wall thermostat (to help regulate how much heat your furnace puts out), and the distribution blower.

The wall thermostat must be connected with 28-gauge thermostat wire (more on that in a bit). The distribution blower, on the other hand, features “plug and play” electrical components that plug into the control center similarly to a wall outlet.

3. Attach the fan limit control

Finally, attach the fan limit control just to the left of the flue exit. The fan limit control is the mechanism that tells the distribution blower when to turn on and off. It does so by detecting the temperature in the plenum — the open area in the top of the furnace just beneath the two ductwork attachment points.

With these three components installed, the draft blower installation process is complete.

Step 5: Install a thermostat

Connecting your FC1000E furnace to a thermostat allows the distribution blower and draft blower to know when to turn on and off to deliver (or stop delivering) heat. We recommend installing a new, separate thermostat (included with your FC1000E furnace) next to your current household thermostat.

A lot of this step should already be done for you: if you have a gas or electric furnace in your home, it should be connected to your current thermostat. We recommend running 28-gauge thermostat wire along the same path as the wiring to your existing home thermostat.

From there, just mount your new, Fire-Chief-specific thermostat on the wall next to your existing thermostat, and connect the 28-gauge wire to the new thermostat and your furnace (the connecting points on the furnace are located on the electrical control center from step 4.2).

Step 6: Connect your furnace to a chimney

When connecting your furnace to a chimney, you have two options:

1. Connect the furnace to an already-existing chimney
2. Build a new chimney and connect your furnace to it

Connecting to an existing chimney is common in older houses that have (or previously had) a coal or wood burning stove. Whatever the case, if you’re connecting to an existing chimney, be sure to have it inspected to ensure it’s in proper working order. It’s also very important not to connect your Fire Chief furnace to a chimney that’s already servicing another appliance.

Each homeowner’s chimney connection process will be unique. But whether you’re installing a new chimney or connecting to an existing chimney, here are a few tips to keep in mind:

• We encourage lining the chimney with a 6” stainless steel chimney liner (this may be required by law in some areas)
• The pipe connecting the furnace to the chimney should be a minimum of 24-gauge black stove pipe
• If you need to install any pipe horizontally, remember that there should be 2” of rise for every 12” of horizontal run

Finally, NEVER use galvanized pipe to connect your wood furnace to your chimney. Doing so will result in the generation of deadly, poisonous gas. Galvanized pipes should be used for air ducting only.

Step 7: Connect your furnace to your ductwork

Next, it’s time to connect your furnace to your HVAC system. Like the chimney connection, each ductwork connection project will be unique. It’s important to note, though, that the two starter collars at the top of the furnace are eight inches in diameter, which necessitates 8” ducts.

You should never use more than a 45-degree elbow when connecting ducts; this will cause the heat not to be distributed correctly. The distribution air should be connected to the ducts at an angle, and should be directed downstream to ensure proper airflow as well.

Step 8: Connect the cold air return

Your furnace’s main function is to distribute heat into your home. Perhaps equally important, though, is to allow air to flow through the filter and into the back of the furnace to keep it functioning properly.

To provide this return air, the simplest option is to promote proper circulation to the area which houses your furnace — usually a basement. There are three good ways to ensure proper air circulation:

1. Simply leaving the door to your basement open
2. Installing louvers in the basement door
3. Installing vent registers in the basement’s return air ducts

If you decide to install vent registers in the basement’s return air ducts, be sure to keep them closed in the summer to allow your air conditioning system to function properly.

If you still have your electric or gas furnace attached to your HVAC system, another option for supplying return air to your Fire Chief furnace is to connect it to the same, already-installed return air system of your existing furnace.

Should you decide to go this route, a word of caution: be sure your existing furnace does not pull your Fire Chief’s heated air into the return air ducts. To prevent this, simply install a damper to the distribution air duct of your existing furnace.

Step 9: Start your first fire

After the electrical components are installed, the chimney is connected, the distribution air ducts are set up, and you’ve ensured your Fire Chief is receiving adequate return air, the installation process is complete! All that’s left to do is plug the furnace into an electrical outlet and start your first fire.

A quick note — if you notice a moderate amount of smoke coming off of your furnace during your first few fires, don’t worry! This smoke is coming from the oils used during the manufacturing process in our factory. The issue should dissipate on its own relatively quickly.

Choosing the right wood burning furnace can seem like an overwhelming, logistically complex process. The purchase tends to involve dozens of variables and hundreds of questions, but the one we hear most often from our customers is, “How much will this cost?” After all, the cost of the furnace itself is half the battle; installing the furnace brings a whole slew of additional options (or hurdles) that affect its price.

At HY-C, our furnace-making operations take place in the same building as our office. From the price of raw materials to a furnace’s function and features, we know exactly what goes into building a wood burning furnace from the ground up. We do it every day.

This comprehensive guide will help you understand — from the price of the unit itself to its installation — how much a wood burning furnace may cost you. We’ll also outline the pertinent questions to ask your installer to help avoid cost-related surprises during a consultation.

How Materials Affect the Price of a Wood Burning Furnace

The price of a wood burning furnace essentially boils down to two distinct factors: the cost of the furnace itself, and the cost of the furnace’s installation. The cost of installation can vary widely, and we’ll touch on that in a bit. For starters, though, let’s talk about the attributes that determine the cost of the actual furnace.

At its core, a wood burning furnace is just a big steel box. The price of steel tends to be volatile; many factors — especially the COVID-19 pandemic — have caused wild fluctuations in the price of steel during the early 2020s. 

For example, at the beginning of 2016, a ton of rebar steel cost about $1,800. By October of 2021, the same amount of the same steel cost nearly $6,000. As you dive into the buying process, keep an eye on the price of steel, as its current rate could impact how much you pay for your furnace.

Some wood burning furnaces may use more steel in their construction than others. Furnaces with thicker steel fireboxes, solid cast iron doors and grates, and other high-quality components will demand higher prices. The upside of a higher price, though, is durability (especially if you operate and maintain the furnace according to the manufacturer’s recommendations).

How EPA Regulations Affect the Price of a Wood Burning Furnace

In 2020, the Environmental Protection Agency issued new performance standards for residential wood burning furnaces. In order to meet the new EPA requirements, furnaces became more complex than ever. The design of the furnaces, the location and size of their intake ports, the airflow throughout the furnaces, and the additional technology to control these (and other) factors can all potentially drive costs up.

Getting a wood burning furnace EPA-approved can add to their cost, too. On average, companies pay about $100,000 to get their wood burning furnace through the process from start to finish. This cost includes permits, fees, research and development, and any other odds and ends associated with the stringent review process.

Companies have no choice but to pass these costs onto consumers since, as of 2017, all new wood burning furnaces need to be EPA-approved. If a company sells 1,000 furnaces a year on average and spends $100,000 to get their furnace approved, they’ll have to add $100 onto the retail price of their furnace to recuperate some of that cost.

How Labor and Location Affect the Price of a Wood Burning Furnace

Once the raw materials are gathered, they need to be assembled into a finished, fully functional wood burning furnace for your home. Like any other product, the nuances of this process have an effect on the final price tag. Today, the United States, Canada, and China are the three most common manufacturers of EPA-certified wood burning furnaces.

Manufacturers in the United States and Canada utilize expensive, skilled labor to assemble their wood burning furnaces. The “Made in USA” sticker is a well-recognized stamp of quality; just be aware that it tends to come at a higher cost. Parts manufactured overseas tend to utilize less expensive labor and lower-quality materials to help keep their prices low. Bear in mind, too, that overseas cost savings may be offset by tariffs and additional freight costs.

After taking tariffs, transportation, steel, and labor into consideration, a furnace made in the USA or Canada costs (on average) about 30% more than a furnace made in China.

Two Additional Features that Impact the Price of a Wood Burning Furnace

A wood burning furnace may just seem like a big, self-contained steel fireplace, but there’s much more to them than that. They come with a variety of bells and whistles that affect how much they cost, how conveniently they operate, and how cleanly they burn. Here are two common features of wood burning furnaces that have an effect on their pricing.

1. Firebox Material and Capacity

The firebox is the portion of the furnace that houses the burning wood. The material from which the firebox is made determines how well-insulated and durable it is, and most fireboxes are made either from firebrick or high-temperature insulation wrapped in stainless steel.

Firebrick absorbs heat, while insulated stainless steel keeps the heat contained in the firebox, ready to be transferred to the hot-air plenum. Both materials are durable and long-lasting, but not without their issues; firebrick can chip and crumble, while stainless steel might become dented over time.

The capacity of the furnace’s firebox is an important consideration, too. Measured in cubic feet, firebox capacity indicates how much wood a furnace can hold. Bigger fireboxes take more material, resulting in a higher price.

2. Blower System

As the fire burns in the furnace’s firebox, warm air needs to be pushed out in order to heat the house or building. The furnace does this by way of a distribution blower, a high-powered fan that forces warm air from the hot-air plenum above the firebox into the air ducts (and, subsequently, into each room of the home). The power of a distribution blower is measured in cubic feet per minute (CFM). The higher the blower’s CFM, the more warm air it can push out of the furnace.

Bigger distribution blowers tend to entail higher price points. A blower with 1,800 CFM has about 40% higher capacity than an 1,100 CFM blower and, as a result, effectively costs about 40% more.

How Much Does It Cost to Install a Wood Burning Furnace?

After you find the right furnace with the right features that meet your needs and budget, the final step is to install it in your home. We do not recommend attempting to install a wood furnace yourself. Instead, you should hire a professional to install your furnace. With that in mind, the question naturally follows: “How much does it cost to install a wood burning furnace?

Coming up with a definitive price is difficult; every home is unique, every furnace is different, and every installation professional charges different rates. As a helpful starting point, there are some good questions to ask, as their answers will determine the cost of your furnace’s installation. Keep these questions (and their answers) handy for your consultation with your installer of choice (and, if you don’t know the answers, be sure to ask your installation professional):

• Are you replacing an existing furnace or installing a new one?
• Do you have an existing HVAC system that your new furnace will be supplementing?
• Will you need to install additional ductwork for return air?
• Do you have an existing chimney or flue?
• Where will your thermostat be installed, and what additional obstacles does its installation entail?

Remember, installation prices may vary from region to region, installer to installer, or furnace to furnace. That said, we can offer an estimated range based on years of experience with furnace installations:

• The lowest-cost, best-case scenario is that of a home with existing ductwork and an existing chimney or flue. Installing a furnace in this situation may cost as little as $300 to $500.
• Furnaces without an integrated plenum require custom sheet metal work. These installations may cost between $300 and $800.
• If your furnace installation requires new ductwork or a new chimney, you could pay as much as $3,000 to $8,000.

Is a Wood Burning Furnace Right for You?

The purchase and installation of a wood burning furnace is clearly not an easy process. From the materials, the size of the firebox, the capacity of the distribution blower and more, there are a lot of complicated variables to consider.

By now, though, you should have a clear idea of which features to look out for, what affects the price of a furnace, and how much its installation will cost. To get an idea of how two furnaces compare and contrast with each other, it’s good to compare two popular models, like the HY-C Fire Chief FC1000E furnace and US Stove’s HB1520 furnace.

And even if you don’t buy either of those furnaces, you’ll still come away with a good understanding of the process of shopping for a wood burning furnace. That will put you well on your way to finding a whole-home wood burning heating solution.

In a world where natural gas home furnaces have become the norm, wood burning furnaces are a commonly overlooked option. They shouldn’t be, though, as they offer an environmentally friendly, cost-effective, and energy-independent way of heating your home (or supplementing your existing furnace).

If you’ve decided to declare your independence from your propane, heating oil, or gas company, the question remains: what is the right wood burning furnace for me?

In order to help answer that question, in this post we’re going to compare two highly regarded, tried-and-true furnaces: HY-C’s Fire Chief FC1000E and US Stove’s Hot Blast HB1520. We’ll consider each furnace’s heat dispersion capabilities, the build quality of each furnace, how easy each furnace is to install, and some important safety considerations to keep in mind. By the end of this guide, you should have a much stronger sense of what to look for in a wood burning furnace, and you’ll be ready to start considering pricing options.

Heat Dispersion Capabilities of Each Furnace

Above anything else, a furnace’s primary function is to deliver heat throughout your home. In wood burning furnaces, that heat is measured through British thermal units (BTUs) — the higher the BTUs, the more heat the furnace can provide. US Stove’s HB1520 is rated for 180,000 BTUs while Fire Chief’s FC1000E tops out at 143,5000 BTUs.

If you live in a frigid area that demands continuous performance from your furnace, the HB1520 might be the better choice for you. However, if the climate in which you live is a little more forgiving, the FC1000E is up to the task.

As wood burns in the furnace, the heat in the firebox needs to be pushed out into the home’s air ducts. Wood furnaces accomplish this by way of a distribution blower. The amount of air a distribution blower is able to push out is measured in cubic feet per minute (CFM). The HB1520 features two distribution blowers which put out 550 CFM each. The Fire Chief FC1000E has one distribution blower, and it’s capable of 1,800 CFM.

Wood Furnace Build Quality

The quality of your wood furnace is what will help determine its longevity. High build quality means less repairs and better overall, long-term performance. Wood burning furnaces are made primarily of steel, a strong, sturdy metal that holds up well long-term.

The Fire Chief FC1000E is made in the USA with domestically sourced steel. Its firebox (the part of the furnace where wood fuel is placed and burned) is designed both with steel and an additional layer of insulation, which means heat won’t escape and will be channeled through your ductwork to heat your home efficiently.

US Stove’s Hot Blast HB1520 is not manufactured in the USA, and it’s made with non-domestic steel. That means it comes with a cheaper price tag than the Fire Chief FC1000E, which might make it a better option for more budget-conscious shoppers.

Ease of Furnace Installation

Regarding the installation process itself, the Fire Chef furnace comes with both pre-wired, “plug and play” electrical components and two duct attachment points to help make self-installation simpler. The Hot Blast may require assistance from a metal fabricator to fashion the ductwork connection. US Stove recommends using a qualified electrician to install the Hot Blast’s electrical components.

It may not be top-of-mind for most customers when making their purchase, but the size of the furnace itself is also an important determining factor when installing it in your home. Maneuvering a furnace to its installation location often includes fitting it through the basement door and down the steps.

The Hot Blast HB1520 measures about 45” x 25” x 54” and weighs around 580 pounds while the Fire Chief FC1000E is a narrower 42” x 26” x 45” and weighs around 435 pounds.

Furnace Door and Clearance to Combustibles

One of the primary safety concerns of a wood furnace is its clearance to combustibles range, or how far combustible materials (like extra firewood or a wall) need to be kept from the furnace to avoid them catching fire. The Fire Chief FC1000E’s clearance to combustible range is six inches, while the Hot Blast HB1520’s is 18 inches.

So think about the area where you want to install your furnace. What’s there? Walls? A work bench? Other combustible materials that can’t be easily moved? If you have more open space, either furnace will work well for you. The Fire Chief FC1000E’s shorter clearance to combustible range makes it a more versatile choice in tighter spaces.

The HB1520 also comes with a glass pane on the front of its loading door. The glass is useful for seeing into the furnace in order to know when to add more wood. The Fire Chief FC1000E features a solid steel door (without a glass viewing pane) that can be locked into place when it’s closed.

Which Wood Burning Furnace is Best for Me?

There’s no simple answer to this question. Everyone’s home, heating needs, and available space are different. Even still, at this point you should have a better idea of the differences between the Fire Chief FC1000E and the Hot Blast HB1520 so you can decide on the best one for you — or even a different wood burning furnace altogether.
