How Does An Outdoor Wood Furnace Work?

To understand how an outdoor wood furnace works, I have found a solution that explains the three important aspects: heat generation, heat distribution, control, and efficiency. 

By reading this, you will know how the furnace generates and distributes heat, and how control and efficiency play a key role in optimizing your investment. 

The subsections will provide a brief glimpse into each of these key aspects.

Heat Generation.

  • Wood furnaces generate heat through combustion
  • Wood is burned, creating hot gases that circulate to keep indoor temperatures up. 
  • Burning wood uses energy from photosynthesis stored in trees.
  • Outdoor wood furnaces burn more efficiently and consistently due to the oxygen supply. 
  • The closed-loop system ensures no fossil fuels are used. 
  • Plus, modern furnaces can fit large volumes of fuel without frequent refueling. 
  • Automation features like thermostats also make manual intervention minimal.

Pro Tip: Always ensure ventilation when installing an outdoor wood furnace. This reduces fire hazards and optimizes heat output. 

Get ready to get burned with your outdoor wood furnace’s firebox; the heart of this heating system!


  • The firebox is the chamber where wood is burned to create heat
  • It’s surrounded by thick insulation, so it can stay hot for a while. As the wood burns, smoke, and gases escape through a chimney.
  • The hot gases heat tubes or plates that transfer the heat to radiators and pipes. Some outdoor wood furnaces have secondary combustion systems to make them burn more efficiently and cleanly.
  • For optimal energy savings and eco-friendliness, make sure to get the right size and install your furnace properly. Make sure to use seasoned firewood with moisture content below 20%.

Wood is the perfect fossil fuel for outdoor wood furnaces.

Fuel Sources.

Outdoor wood furnaces need certain fuel types. The most common ones are listed in a table with columns about Fuel Type, Moisture Content, Heating Value (BTU/Lb), Estimated Cost Per Cord, and Advantages/Disadvantages.

Besides these, some may use corn cobs, sawdust, and other materials. These need modifications to the furnace and burner.

Surprise! You can also use waste oil in your outdoor wood furnace. This is a cleaner way of heating than normal fuels.

Goodbye, traditional fireplace! Hello, an outdoor wood furnace that turns your yard into a cozy fire!


Gasification is a special process for outdoor wood furnaces. It changes organic materials into flammable gases when heated without oxygen. This makes the furnace more efficient and lowers emissions. 

See the table below for an explanation of the gasification process:

Heating upFresh air comes into the stove and warms the firebox.
PyrolysisThe wood breaks down and sends out volatile gases.
GasificationThe gases mix with air and burn at a high temp. This produces heat.
Ash RemovalThe ash falls into a separate chamber for removal.

Gasification is remarkable as it can reduce emissions much more than regular wood stoves. Plus, it barely produces visible smoke.

Pro Tip: Keep your outdoor wood furnace clean and replace any broken parts to get the best results. 

Wood furnaces make for a great outdoor experience; not quite the same as a bonfire, but still fun!

Heat Distribution.

For a cozy outdoor setting, it’s key to know how heat is spread by an outdoor wood furnace. 

Take a look at the table below. It shows the heat production for different distances from the furnace and near buildings.

Beyond 100 feetLow

Heat distribution can change due to several factors, such as:

  1.  Insulation.
  2. Wind.
  3. Individual weather. 

To make sure the heat reaches where it needs to, avoid any kind of obstruction between the furnace and the area. 

Enjoy the feeling of warmth with a furnace that runs on nature and a spark of fire!

Water Heating.

Water heating is an essential part of an outdoor wood furnace. 

  • This process warms the water and then moves it through tubes to the building.
  •  The combustion chamber is where the wood burns and heats the water. 
  • The water jacket surrounds the chamber and contains the heated water
  • A heat exchanger moves the heat from the water in the jacket to a different closed-loop water system. It then delivers hot water to the building.

Most outdoor wood furnaces share a similar design and goal; efficient heating powered by renewable resources. 

They were invented in Switzerland for industrial use during WWII, and are still gaining popularity due to their efficiency and eco-friendly nature. 

Nothing can top the feeling of warm air coming from the furnace, plus knowing you’re not adding to your electricity bill.

Forced Air.

  • A popular method of distributing hot air from an outdoor wood furnace is to use forced air. 
  • A blower sends the hot air through ducts that are installed in the living area.
  •  This causes pressure differences, resulting in the hot air being circulated in the house.

To help understand how the system works, we made a table. It shows info about the blower size and type, electrical specs, duct size and material, air filters, and any additional equipment needed.

Blower 3 HP
TypeCentrifugal Blower
Electrical Specs115/230VAC 20Amp Draw
Duct Size & Material8″ Round Spiral Duct
Air Filters16x20x1 Pleated Filter
Additional EquipmentThermostat Control
  • Gravity ventilation is used to allow cool air to enter the furnace. This is to stop any dangerous flue gases from entering the living space.
  • The forced-air distribution method offers lots of advantages compared to other heating options. It can function at lower temperatures than other methods, yet still provide an even supply of warm air.

My uncle installed an outdoor wood furnace in his farm home and chose the forced-air distribution method. His energy bills dropped dramatically as he didn’t have to frequently refill fuel oil tanks; this removed running costs. The system also gave more comfortable ambient temperatures on cold days compared to his older oil-based central heating system.

Forced-air distribution packs a punch when it comes to hot air from an outdoor wood furnace!

Blower Fan.

The blower fan of the outdoor wood furnace is essential for circulating hot air

This boosts the heating process and keeps a consistent temperature. It is a centrifugal fan, with variable speed, up to 2300 CFM, and 1/5 HP power consumption.

Maintenance is key for its longevity and proper functioning. That includes cleaning or changing air filters and checking for wear or damage.

My friend had an issue with his blower fan. He tried to fix it himself but ended up causing more damage. He had to call a professional technician to repair it. 

Moral of the story: Don’t mess with complex equipment.

Make sure your outdoor wood furnace is functioning well. It’s no fun having a cold stack of firewood on a chilly night!

Control and Efficiency.

Heating with an outdoor wood furnace has lots of variables.

 Increase efficiency by using a blower or fan system to get the right amount of air inside the furnace. The heat exchange system also helps, transferring the heat to water or air. Quality fuel, maintenance, and insulation make it even better.

Positioning the furnace near the house reduces heat loss. Keep the furnace and fuel storage close together too. 

Don’t overfill the furnace with wood;  it can decrease combustion efficiency and increase pollution.

Remember to clean the ashes regularly for the best performance. 

 Who needs a thermostat when you can just adjust your mood by adding another log to the fire?


A Key Element of Heating.

The thermostat plays a vital role in the outdoor wood furnace process. It helps to control the home temperature.

 Let’s take a look at what it does:

Adjusts OutputAdjusts output temperatures for ideal room temperatures.

This small component is essential for optimal heating.

It’s worth noting that different thermostats work differently, based on their mechanism. Another important factor when using an outdoor wood furnace is the type of firewood. A resident once told us about his experience with dried-out firewood left outside too long. It caused a bad burn and pricey chimney repairs. This serves as a reminder to choose the right firewood for efficiency.

Who needs privacy when you can have custom heated zones?

Heating Zones.

A Key Feature: Multi-Zone Heating.

An outdoor wood furnace often has multiple zones for heating a whole house or building. These zones can be managed separately, cutting down energy waste and improving efficiency.

To understand multi-zone heating better, look at this table:

ZoneTemperature Setting

Here we have three zones with different temperatures. Zone 1 could be the living room, Zone 2 a guest bedroom, and Zone 3 a closed-off storage room.

Multi-zone heating only warms up the areas that are needed. This saves energy and lowers utility bills.

  • Additional Considerations.

Think about zone size, insulation, and unit maintenance when setting up multi-zone heating

  1. Too much space in a zone leads to more energy usage.

Frequently Asked Questions. 

Q: What is an outdoor wood furnace?

A: An outdoor wood furnace, also known as an outdoor wood boiler or a wood-fired hydronic heater, is a heating system that uses wood as its fuel source to provide heat for residential or commercial spaces. It is typically located outside the building it heats and operates independently of the indoor heating system.

Q: How does an outdoor wood furnace work?

A: An outdoor wood furnace works by burning wood in a firebox or combustion chamber to generate heat. The heat is then transferred to water or a heat transfer fluid, which circulates through pipes to deliver heat to the desired location. The heated water can be used for various applications, such as heating the building, providing hot water, or even heating swimming pools or hot tubs.

Q: What are the main components of an outdoor wood furnace?

A: The main components of an outdoor wood furnace include a firebox or combustion chamber, a heat exchanger, a water jacket, a circulation pump, piping, and controls. The firebox is where the wood is burned, producing heat. The heat exchanger transfers the heat from the firebox to the water or heat transfer fluid. The water jacket surrounds the firebox, containing the water or fluid. The circulation pump helps circulate the heated water throughout the system, and the piping connects the different components. The controls manage the operation of the furnace, including temperature regulation and safety features.

Q: How is the heat from the outdoor wood furnace distributed inside the building?

A: The heat from the outdoor wood furnace is typically distributed inside the building through a hydronic heating system. In this system, hot water from the furnace is circulated through pipes that are connected to radiators, baseboard heaters, or radiant floor heating systems. The hot water releases its heat to the surrounding air or surfaces, thereby heating the indoor space.

Q: Are outdoor wood furnaces efficient?

A: Outdoor wood furnaces can be efficient heating systems when properly installed and maintained. The efficiency depends on factors such as the design of the furnace, the quality of insulation, the type of wood used as fuel, and how well the system is operated. High-quality outdoor wood furnaces can have efficiencies of around 80% or more, meaning that a significant portion of the wood’s energy is converted into heat.

Q: What are the advantages of using an outdoor wood furnace?

A: Some advantages of using an outdoor wood furnace include:

  • Cost savings: Wood is often a more affordable fuel source compared to electricity, oil, or gas. By using wood as fuel, you can potentially save on heating costs.
  • Independence from traditional energy sources: With an outdoor wood furnace, you are not reliant on electricity, oil, or gas to heat your space. This can be beneficial in areas with unreliable or expensive energy supplies.
  • Renewable and sustainable: Wood is a renewable energy source, especially when sourced responsibly. Using wood as fuel can help reduce your carbon footprint and contribute to sustainable energy practices.
  • Versatile applications: Outdoor wood furnaces can provide heat for multiple purposes, including space heating, hot water production, and heating for other structures like pools or hot tubs.
  • Reduced indoor air pollution: By locating the combustion process outside the building, an outdoor wood furnace helps minimize indoor air pollution that can occur with traditional indoor wood stoves or fireplaces.
  • Long lifespan: Outdoor wood furnaces are typically built to be durable and long-lasting, with some models having a lifespan of 20 years or more when properly maintained. 


Outdoor wood furnaces offer great practicality for heating indoor and outdoor spaces. Burning seasoned wood in a firebox heats the water jacket surrounding it. This heated water is circulated either underground or into an indoor boiler, distributing warm air or hot water via blower fans. Some extra tools and accessories can help manage performance, such as a thermostat or control panel. Gasification features may also reduce creosote build-up. When buying an outdoor wood furnace, capacity is important. They come in a range of sizes, from 750 square feet to over 10,000. Firewood access is key. Stacking and seasoning firewood annually can save money and make using the furnace simpler. An outdoor wood furnace is a great cost-saver. It provides comfortable heat during winter and keeps cold air out. Proper care and good fuel practices make it even easier to enjoy!
