What Is a Pellet Stove? Your Ultimate Guide to Efficient Home Heating

If you’re exploring alternate home heating methods, you’ve probably come across pellet stoves. But what is a pellet stove, and how does it work? These modern heating appliances are great for residential spaces, and they’ve gained popularity for their efficiency, eco-friendliness, and cost-effectiveness compared to traditional heating methods. If that all sounds amazing, keep reading to learn more. 

What Is a Pellet Stove?

A pellet stove is a type of stove that burns small, compressed pellets made from biomass materials like sawdust, wood chips, agricultural waste, or even paper. These pellets are automatically fed into the combustion chamber so that the stove can operate through a controlled burn. You can regulate a pellet stove with a thermostat or a control board, which ensures consistent and efficient heat output for your home.

How Do Pellet Stoves Work?

Pellet stoves operate using a few key components. Some of the most vital parts of a pellet stove and their jobs include the following: 

• A hopper to store pellets

• An auger system to feed pellets into the burn pot

• A combustion fan to supply air for combustion

• A heat exchanger or flue to transfer heat into the living space

The pellets ignite via an electric igniter, and the combustion process is controlled electronically for optimal efficiency. Then, the ash from the burnt pellets collects in the handy ash pan for easy removal. Proper ventilation for a pellet stove is important so that the smoke (though minimal) escapes safely.

Pellet Stove vs. Wood-Burning Stove: What's the Difference?

Unlike traditional wood-burning stoves, which require you to manually add wood, pellet stoves offer automated fuel delivery and combustion control. This makes them easier to use and more efficient. Pellet stoves also produce fewer emissions than wood stoves and require less manual labor for operation and maintenance.

Pellet Stove Pros

Pellet stoves offer several advantages over both traditional home heating systems and wood-burning stoves. The biggest benefit is that they are highly efficient, with some models boasting efficiency ratings of over 90%. This means more heat produced for less fuel consumed, translating to lower heating costs.

Here are some of the top benefits of pellet stoves:

• Efficient heating: Pellet stoves can heat large areas effectively due to their high heat output and efficient combustion process.

• Eco-friendly: They burn cleanly and produce low emissions, contributing to better air quality compared to wood stoves.

• Reduced heating costs: When you compare traditional heating systems like propane to pellet stoves, operating costs for pellet stoves are lower. This is especially true if you use pellets sourced locally or from sustainable materials.

• Easy operation: Compared to wood-burning stoves, pellet stoves are easier and cleaner to operate. They require less frequent refueling and produce minimal ash.

Pellet Stove Cons

Despite their benefits, pellet stoves do have some drawbacks to consider.

Angi Tip

If you're regularly using your pellet stove, you should empty the ash pan, clean out the burn pot, and wipe down the window every week. You should also clean the vent pipes at least once per year, depending on how often you burn.

• High-maintenance: Regular cleaning of ash and maintenance of mechanical parts like the auger and fans are necessary to keep the stove running efficiently.

• They take up space: Pellet stoves require space for the unit itself, as well as clearances around it for safety and ventilation.

• Electricity required: Pellet stoves rely on electricity to power the auger, fans, and sometimes the ignition system, which means they won't operate during power outages unless they’re connected to a backup power source.

• Higher cost than wood-burning stoves: Initial purchase and installation costs for pellet stoves tend to be higher than those of wood-burning stoves.

Types of Pellet Stove Fuel

Fuel is an important factor to think about when you’re considering installing a pellet stove. These stoves can burn various types of pellets, each with its own benefits and characteristics.

Wood Pellets

Wood pellets are made from compressed sawdust and wood shavings. They are widely available and offer consistent heat output, making them a top choice for pellet stove owners.

Corn Pellets

These pellets are made from dried corn kernels and can be a budget-friendly alternative to wood pellets, though they may require adjustments to the stove's settings.

Miscellaneous Biomass Pellets

Pellets made from agricultural by-products like cherry pits or olive pits offer unique heating options. However, they may be less readily available, making them a higher-cost option.

Will a Pellet Stove Heat an Entire House?

The heating capacity of a pellet stove varies based on its size and efficiency rating. Larger models can heat entire homes, especially when strategically placed in central locations or where airflow is optimized. However, for larger homes or in very cold climates, supplementary heating may be necessary.

Can You Install a Pellet Stove Yourself?

While installation is possible for exceptionally advanced DIYers, it’s best left to professional installers or those with carpentry skills and knowledge of venting requirements. Local stove companies can ensure proper venting, compliance with building codes, and safe operation of your new pellet stove.

How Much Does a Pellet Stove Cost?

The cost of a pellet stove varies widely based on the stove’s size, features, and brand. On average, prices range from $1,000 to $3,600 for the stove itself, with installation costs adding several hundred to over a thousand dollars, depending on complexity. In comparison, a wood-burning stove costs between $325 and $4,000.
