Your Guide to Choosing the Best Outdoor Wood Burning Furnace
An outdoor wood-burning furnace is a powerful way to heat your home, shop, or even a greenhouse. These large furnaces sit outside your building. They burn wood to create heat. This heat then moves to your building through underground pipes. Choosing the right one takes careful thought. This guide helps you pick the best furnace for your needs.
Key Features to Look For
When shopping, certain features make a big difference in how well your furnace works. Look closely at these points.
1. Heat Output Capacity (BTUs)
Furnaces are rated by British Thermal Units (BTUs). This number shows how much heat the furnace can produce. You must match the BTU rating to the size of the area you need to heat. A small cabin needs less power than a large workshop. Check sizing charts to find the right fit. Too small, and you will always be cold. Too big, and you waste wood.
2. Water Jacket Thickness and Design
The water jacket surrounds the firebox and holds the water that gets heated. Thicker steel means the furnace lasts longer. Look for jackets that are at least 1/4 inch thick, or even thicker for heavy use. Good design helps move heat into the water quickly and evenly.
3. Secondary Combustion System
Modern furnaces include a secondary burn. This feature burns the smoke and gases that would usually escape up the chimney. This makes the furnace much more efficient. It uses less wood and creates less pollution. It is a must-have feature for clean burning.
4. Ease of Loading and Ash Removal
You will load wood often. A large, easy-to-open loading door saves your back. Similarly, the ash pan should slide out easily. Cleaning the furnace should not feel like a huge chore.
Important Materials Matter
The quality of the materials directly impacts the furnace’s lifespan and safety.
- Steel Quality: Most good furnaces use heavy-gauge, high-quality steel. Stainless steel components resist rust better than standard steel.
- Insulation: Look for thick insulation around the firebox. Good insulation keeps the heat inside the unit, sending more heat to your home instead of letting it escape into the cold air.
- Piping and Connections: Check the quality of the plumbing connections. Strong fittings prevent leaks and ensure safe heat transfer to your home.
Factors That Improve or Reduce Quality
What makes one furnace better than another? Small details often separate the best from the rest.
Quality Boosters:
- Turbo Fans/Blower Systems: These help push more air into the fire, making the burn hotter and more complete.
- Digital Controls: Modern thermostats let you set the exact temperature you want your circulating water to reach. This prevents overheating and saves wood.
- Warranty: A long warranty, especially on the firebox and water jacket, shows the manufacturer trusts their product.
Quality Reducers:
- Thin Walls: Thin metal burns through faster due to constant high heat and exposure to water.
- Poor Welding: If welds look sloppy or uneven, they are weak points where cracks can start.
- Lack of Certification: Always choose a furnace that meets safety standards (like EPA or local codes). Uncertified units can be unsafe.
User Experience and Use Cases
Think about how you will actually use the furnace.
Daily Use:
If you plan to use it daily during winter, you need a large firebox that holds big logs. This means fewer trips outside to refuel. If you only need heat occasionally, a smaller model might work better.
Installation and Maintenance:
Outdoor furnaces require professional installation to connect the underground pipes to your home’s heating system (usually your existing furnace or water heater). Check if the manufacturer provides clear instructions or good dealer support for setup. Routine maintenance involves cleaning the ash and checking the water level.
Outdoor wood furnaces are great for heating large properties, workshops, or homes far from natural gas lines. They offer energy independence, but they require commitment to loading wood and performing maintenance.
Frequently Asked Questions (FAQ)
Q: How far away from my house can I place the furnace?
A: Most manufacturers allow distances up to 100 to 200 feet. This depends on the type of piping used. Longer runs require better insulation to prevent heat loss.
Q: Do I need a special type of wood to burn?
A: You should always burn dry, seasoned hardwood. Wet wood creates excessive smoke, lowers efficiency, and can cause creosote buildup in your pipes and chimney.
Q: Is an outdoor wood furnace cheaper than propane or electric heat?
A: If you have a free or cheap source of wood, yes, it is usually much cheaper to operate. The initial purchase and installation costs are high, though.
Q: What is the typical lifespan of a quality outdoor furnace?
A: Well-maintained, heavy-duty furnaces often last 20 to 30 years. The lifespan depends heavily on the thickness of the steel water jacket.
Q: Does an outdoor furnace work with my existing central air system?
A: It usually connects to your existing ductwork via a heat exchanger, which transfers heat from the furnace water to your home’s air. It typically replaces your existing furnace as the primary heat source.
Q: Is the smoke from an outdoor furnace a problem?
A: Modern furnaces with secondary combustion produce very little visible smoke, especially when running hot. Older or poorly maintained units produce more smoke.
Q: What permits do I need before installing one?
A: You almost always need local building and sometimes air quality permits. Always check with your town or county office first.
Q: Can I heat my domestic hot water with this furnace too?
A: Yes, many models offer an optional “water-to-water” heat exchanger that can preheat your household hot water, saving you money on your water heater.
Q: What is the biggest maintenance chore?
A: Removing the ash from the firebox and checking the water levels and pressure in the system are the most frequent tasks.
Q: Are there environmental concerns with these furnaces?
A: Yes, burning wood creates emissions. This is why choosing an EPA-certified unit with secondary combustion is important to reduce pollution.
