With energy costs on the rise, many homeowners are looking for affordable and efficient ways to heat their homes. Two popular options are wood stoves and pellet stoves. But which is the better choice – wood heat or pellet heat? This comprehensive guide examines the key differences between wood stoves and pellet stoves to help you decide which heating system is right for your needs.
How Wood Stoves and Pellet Stoves Work
To understand the differences between wood stoves and pellet stoves, it helps to first look at how each system works.
Wood Stoves
Wood stoves burn split firewood as fuel. Pieces of firewood are loaded into the stove through a front or top opening. Inside the stove, the wood fuel burns and releases heat. Wood stoves have basic controls to regulate the air flow and rate of burn. Most wood stoves use natural draft without a fan to pull air through the combustion chamber.
Some key features of wood stoves:
- Burn split, stacked firewood
- Release radiant and convection heat
- Manually loaded and controlled
- Natural draft design without a fan
- Basic controls for air flow regulation
Pellet Stoves
Pellet stoves burn compressed wood pellets made from recycled sawdust and wood waste. The pellets are fed into a burn pot using an electric auger system. Forced air fans circulate heated air from the burning pellets into the room. Pellet stoves are controlled via digital controls and thermostats.
Some key features of pellet stoves:
- Burn compressed wood pellets
- Auger automatically feeds pellets to the burn pot
- Forced hot air circulation with fans
- Digital controls and thermostats
- Can be vented or direct vent
Now that we’ve looked at the basic operation of each type of stove, let’s dig into the details of how they compare.
Fuel Source Comparison
The main difference between wood stoves and pellet stoves is the type of fuel they require.
