Below are my top picks for the smallest pellet stoves available on the market. Each one is under 24 inches in width, perfect for keeping cozy spaces warm.
1. ComfortBilt Pellet Stove HP22 – Editor’s Pick
The first product on this list is the ComfortBilt Pellet Stove HP22.
This best-selling pellet stove boasts a robust heating capacity while maintaining a compact build. It is rated at 50000 British Thermal Units (BTU), which can easily heat up to 2,800 square feet of area. Meanwhile, the dimensions of the stove are 25 inches deep, 24 inches wide, and 32.5 inches tall. It can fit most rooms without taking up too much space. There is also a relatively large bay view window to help you see the ongoing fire.
Another benefit of this small pellet stove is the 55-pound hopper capacity. It can accept a bag of pellets, unlike other compact stoves.
And speaking of pellets, the ComfortBilt HP22 stove can burn them completely. The ashes fall automatically on a removable ash pan, which is easy to clean.
This compact pellet stove can also run up to 20 hours on the lowest setting. Feel free to choose from five different power settings. You can also program the 7-day internal thermostat to maintain a comfortable temperature automatically. You can even ensure economical pellet use with this feature.
Finally, this pellet heater meets EPA and CSA Certifications. It complies with all federal emissions mandates to prevent polluting the environment.
Despite these benefits, the ComfortBilt HP22 has a few downsides worth considering. Some users noticed a plastic-burning smell when they used the stove for the first time. A few reviews also mentioned the hopper lid was small.
The pros far outweigh the cons, so I highly recommend checking the ComfortBilt Pellet Stove HP22. It may be the ultimate heating solution for smaller spaces.

How to Choose the Best Smallest Pellet Stove?
If you’re still undecided about which small pellet stove to buy, don’t fret. Below, I’ll share the five important factors to consider before finalizing your purchasing decision.
Dimensions
First things first, you must check the exact dimensions of the pellet stove. You need to ensure it would fit your room.
If you have very limited space, consider the width and depth of the appliance. Slimmer models that are less than 20 inches wide are ideal for small rooms.
The last thing to check is the height since it doesn’t take up the floor area. That said, it’s an important factor to check if you’re planning on buying a pellet stove insert.
However, you must know that more compact stoves mean smaller control panels and hoppers. You may find it difficult to operate the appliance and put pellets inside.
Heat Output
A small pellet stove doesn’t necessarily mean a weak device. You can find many compact models with a powerful heat output.
Look for the British Thermal Unit (BTU) when shopping for the smallest pellet stoves. The higher the BTU, the more powerful the unit is. For example, the ComfortBilt HP22, which is rated at 50000 BTU, has a higher heat output than the HP50S (42000). As such, it can heat a larger area quicker. It also offers a more efficient heating.
Hopper Capacity
The hopper fuel capacity is another important consideration before buying a small pellet stove.
Some models have a limited hopper capacity. That means you may need to pour pellets multiple times a day, especially during the winter when the temperatures are freezing.
Meanwhile, other compact pellet heaters offer a relatively large hopper capacity. This can typically accept one full bag of pellets, letting the unit run for longer periods.
Maintenance
The ease of maintenance is often overlooked when shopping for a pellet stove. Most homeowners end up buying a model with complicated parts that are hard to reach and clean. They eventually regret their purchase.
So before investing in a pellet stove, make sure to learn how to clean it. Determine whether the ash pan and fire pot are removable to maximize convenience. You must also inspect the stove design carefully. Does it have inner tubes or hidden chambers? If so, avoid that specific model if you can because they are likely a hassle to clean.
Cost
Finally, set a budget when buying a small pellet stove. It comes in different price points, depending on the power output, build quality, and brand, among other factors. Expensive models tend to use higher-quality materials and offer advanced features, such as built-in WiFi and non-electric functionality. If you’re on a budget, don’t expect a stove below $500 to work properly. Decent units start at around $1,000.
Besides the price tag, you must also consider the cost of pellet fuel, repairs, and maintenance in the future. High-end stoves tend to burn pellets more efficiently, so you can use fewer bags. They are also built to withstand many years of usage, preventing costly repairs in the future.
Conclusion
All of my recommended small pellet stoves above have great product reviews and quality features. I’m confident you can find the perfect model for your needs.
My absolute favorite is the ComfortBilt Pellet Stove HP22. It’s small yet powerful, capable of heating up to 2,800 square feet of area. I also appreciate its 55-pound hopper capacity. It can run up to 20 hours in a low-heat setting. And if I need to crank up the temperature, it’s easy to do so with the programmable settings.
