Choosing Your Indoor Wood Furnace: A Buyer’s Guide
An indoor wood furnace can be a smart way to heat your home. It uses wood, a renewable fuel, to keep you warm. This guide helps you pick the right one for your needs.
Key Features to Look For
When shopping for an indoor wood furnace, several features really matter. Think about these things before you buy.
Heating Capacity (BTUs)
- Check Your Home Size: Furnaces have a British Thermal Unit (BTU) rating. This number tells you how much heat it makes.
- Bigger Isn’t Always Better: A furnace too big for your space wastes wood and creates smoke. A furnace too small will never keep up on cold days.
- Get Advice: Ask an expert to help you calculate the right BTU size for your house square footage.
Efficiency Rating
- How Much Heat You Keep: Efficiency tells you how well the furnace turns wood into usable heat. Higher numbers mean you use less wood for the same warmth.
- EPA Certification: Look for furnaces certified by the Environmental Protection Agency (EPA). These models burn cleaner and hotter.
Burn Time and Load Size
- Longer Burns: Some furnaces let you load wood and let it burn for many hours without reloading. This is great for overnight heating.
- Firebox Size: A larger firebox lets you fit bigger logs. This means less time spent chopping and loading wood.
Important Materials and Construction
The materials used determine how long your furnace lasts and how safely it operates. Quality construction is crucial.
Steel vs. Cast Iron
- Steel Furnaces: These heat up fast and are often lighter. Good quality steel furnaces use thick plating to resist warping.
- Cast Iron Furnaces: Cast iron holds heat for a long time, even after the fire dies down. It is very durable, but it can sometimes crack under extreme temperature changes.
Baffles and Secondary Combustion
- Baffles: These are plates inside the furnace. They force smoke and gases to take a longer path before leaving. This lets more heat enter your home.
- Secondary Burn: High-quality furnaces have systems to burn smoke particles a second time. This boosts efficiency and reduces pollution.
Factors That Improve or Reduce Quality
A few design choices greatly affect how well your furnace works day-to-day.
Air Control Systems
- Manual Dampers: These require you to constantly adjust levers to control the fire’s speed.
- Automatic Thermostats: Better furnaces use thermostats that control the airflow automatically. This keeps the temperature steady without you constantly checking it.
Ash Removal and Cleaning
- Easy Access: Look for large, easy-to-remove ash pans. Cleaning the ash should not be a huge chore.
- Firebox Lining: Firebrick lines the inside of the firebox. Good quality firebricks protect the metal shell and keep the heat intense. Worn or thin bricks reduce quality quickly.
User Experience and Use Cases
Think about how you plan to use the furnace in your life.
Primary vs. Secondary Heat Source
- Primary Heat: If the furnace must heat your whole house all the time, you need a high-efficiency, large-capacity model.
- Secondary Heat: If you only use it to supplement your existing furnace or heat a basement area, a smaller, simpler model works fine.
Installation and Placement
- Clearances: All wood furnaces need safe space between the unit and walls (clearances). Check local building codes before you buy to ensure you have enough room.
- Ductwork Connection: Most indoor furnaces connect to your existing heating ducts. Ensure the connection process is straightforward for your home setup.
Frequently Asked Questions (FAQ)
Q: How much wood does an indoor furnace use?
A: This depends heavily on the size of your house, how cold it is outside, and the efficiency of the furnace. A very efficient furnace might use half a cord of wood to heat a small home for a season, while a leaky, older unit could use much more.
Q: Are indoor wood furnaces safe?
A: Yes, when installed correctly. Safety relies on following the manufacturer’s instructions exactly. Proper installation includes correct chimney height, safe wall clearances, and approved venting materials. Never use unapproved fuel.
Q: What is the difference between a wood stove and a wood furnace?
A: A wood stove heats the room it is in directly. A wood furnace is designed to connect to your home’s ductwork, blowing heated air throughout the entire house, much like a gas furnace.
Q: Can I use wet or green wood?
A: No, you should not. Wet wood (green wood) wastes energy boiling off the water inside it. This creates lots of smoke, creosote buildup in your chimney, and very little heat. Always use dry, seasoned wood.
Q: How often must I clean the chimney?
A: If you burn efficiently, most experts suggest cleaning your chimney at least once a year. If you notice heavy, black, sticky buildup (creosote), you must clean it immediately for fire safety.
Q: Do I need a special chimney?
A: Yes, you need a chimney rated for wood heat. Most modern furnaces require a Class A, insulated chimney pipe. Old masonry chimneys might need inspection or relining before they can safely vent a new furnace.
Q: What maintenance is required besides cleaning the ash?
A: You should regularly check the gaskets around the doors to ensure they seal tightly. Also, inspect the firebricks for cracks and look at the blower motor (if applicable) once a year.
Q: How loud are these units when running?
A: A modern, high-quality furnace will make noise primarily from its blower fan when it is actively circulating warm air. The fire itself is quiet. If you hear loud rattling or banging, something needs adjustment.
Q: What is creosote, and why is it bad?
A: Creosote is a flammable, tar-like substance that builds up when wood smokes instead of burning cleanly. It coats the inside of your chimney. If it gets hot enough, creosote can cause a dangerous chimney fire.
Q: Are there any ongoing costs besides wood?
A: Yes. You will have costs for chimney cleaning, replacement parts like gaskets or firebricks down the road, and perhaps electricity to run the circulation fan.
