Castle 12327 – Best overall
- Can manually set the thermostat to one of the five burn levels given as well as set your local thermostat
- Minimal construction to deliver easier usage or maintenance process
- Allow for a wide range of control systems
- No ash pan
- Run loudly
- Small hopper
While keeping a modest footprint to take less space in your house, the stove gives an impressive heating capacity of up to 1,500 square feet and takes 7-10 minutes to get the heat pumping.
It’s clearly superior when compared to other stoves that I’ve tried which usually took not less than 15 minutes to start pumping out their full heat. For that highlight, this is really a useful stove to use during cold days when you forget to program your stove to automatically switch on.
I appreciate the Smart Controller that gives me lots of control systems, from using the manual settings and thermostat to choosing the weekly operation mode. This function also has a calendar and a time-based heating option.
Besides, there’s no tube, corrugations, nor hidden chambers, which is another big bonus since you can easily use or clean it.
|Dimension(W*H*D)||18.25″ x 34″ x 23.75″|
|Heat Area||1500 square feet|
|Automatic Burning Time||12 Hours (High Setting) – 24 Hours (Low Setting)|
|Consumption for Pellet||0.7 – 1.5 kg/hr.|
|Hopper Capacity||40 lbs.|
|Highlight Feature||Smart Controller, easy to clean, includes calendar and time-based heating options|
If you’re only finding a small pellet stove to heat up a small area, the adjustable thermostat and smart controller of Castle 12327 could meet your demands on different days.
US Stove 5660 – User friendliest
- Give a more expanded view through the large bay design
- Allow you to adjust the amount of heat
- Powerful and effective blower for more heating efficiency
- Small hopper -> pellets stop feeding too fast
- Loud fans
The biggest bonus lies in the ventilation system since it only allows directly venting hot air from the stove, hence, you can add some vertical ventilation prior to diverting the duct out of your house. It accordingly minimizes the risks of any problem in case of a power outage.
I myself love that fact that US Stove 5660 is designed with 6 different heat settings that you can adjust the amount of heat distributed due to the warmth preference, kinds of weather, or areas.
Particularly, the electricity blower of this pellet stove is smartly designed with automatic circulation for more efficient air pumping into the burn pot.
|Dimension(W*H*D)||26.2 x 24.2 x 30.5 inches|
|Heat Area||2,200 square feet|
|Automatic Burning Time||60 hours|
|Consumption for Pellet||0.42 kg/hr|
|Hopper Capacity||55 lbs.|
|Blower Power||120 CFM|
|Highlight Feature||6 heat settings, 120 CFM blower with automatic circulation, digital control board, LED display, large bay window style door with air wash glass|
If you’re not good at using big home furnaces, I believe that the minimal LED display, user-friendly heat settings and visual bay window design of US Stove 5660 will gain your highest score.
Napoleon TPI35 – Best pellet stove insert
- Durable build to last for years
- Powerful, effective, and reliable heating
- Super clean burning (get EPA compliant) to be eco-friendlier and more economic
- Relatively thin metal case -> cause metallic popping sounds sometimes during usage
- Too loud blower

By using a fully-renewable fuel source including a mix of 50% corn and pellets, the stove features an impressive 76.3-percent heating efficiency.
It’s also an incredibly clean burner that generates really little creosote (not to say ash). Hence, while discharging a lot less gunk and ash to be eco-friendlier and even get EPA compliant, Napoleon TPI35 also helps you save more money.
Fans of this stove also love it for the super-high output BTU, up to 38250 with reliable heating even when it just consumes subpar fuel, such as semi-dry wood. I think its powerful 120 CFM blower is the best workhorse in this spectrum.
For ease of use, it comes with auto ignition, thermostatic control, Flashing with Black Trim, digital control panel, and heat exchange.
|Dimension(W*H*D)||21.25W x 30.3125H x 25.875D|

To match such enormous emitted power, the hopper is expanded significantly to hold 55 pounds of pellets on each feeding time. That amount is really big to keep the stove last several days before needed replenishing the supply.
While being the best workhorse in heating your entire house, I’m quite amazed that Comfortbilt HP22 is rather easy to use.
With it, you’ll get more control over your heating experience thanks to the programmable thermostat, large viewing area, removable ash pan, and digital control panel.
The stove is also quite to operate that when sleeping, reading, or socializing at home, I’m not disturbed by any annoying sound coming from this furnace.

What I appreciate the most is despite the low price tag, this stove is still built with fully functional features, from a smart controller, auto ignition to electronic controls.

It’s easy to use and also features a comfort control system with 5 different settings to avoid your living space from overheated. Take note that the stove works its best when fueled with premium pellets.

How to choose the most efficient pellet stove (buying guide)?
To determine whether a pellet stove is efficient or not, one of the first indicators you need to concern is BTU rating (stand for British Thermal Units).
1 BTU equals the heat amount needed to raise the temperature of 1 pound of water by 1ºF.
This is the measuring unit of heat output and when shopping for a pellet stove, the salesman might also quote two other relating measurements:
- BTU input: The max fuel amount that your stove needs each hour
- BTU output: The total heat amount that the stove can give.
Don’t misunderstand them as it will help you calculate the next indicator.
Percent (or %) is the measuring unit of a stove’s heating efficiency, following the formula:
Heating Efficiency Perfect = (BTU input/BTU output) * 100
When reading any pellet stove’s product description, chances are that you will see this number, usually within 75% to 90%. It tells you how much of the heat that’s created from the pellet burnt is truly usable in your house.
The higher the number, the more the stove can do with its heat generated.
There are three pellet types (based on the material made of them) at the current:
- Corn (the latest type)
These material kinds are actually bio-mass wastes that had been grounded up, compressed, and extruded. It means you are turning wastes into energy to lessen your dependence on oil or other kinds of fuel.
In terms of the heating efficiency percent (= (input BTU/output BTU) * 100), softwood is the best, and also the most expensive.
Hardwood and corn, on the other hand, give almost same-same heating efficiency but corn will deliver higher ash content to require more maintenance.
Hence, corn is the cheapest.
An electric blower takes the role of feeding air to the fire to help pellets burn as efficiently and hotly as possible. Hence, the smarter the blower’s build, the more effective the generated heat.
Who makes the most efficient pellet stove?

Are pellet stoves dangerous?
No stoves can give you 100% safety when they are running.
With pellet stoves, considerable dangers still exit BUT they are not lethal, mostly coming more from human and environmental factors rather than health risks.
As this kind of stove still requires little electricity to feed the pellets into its hopper, it turns outrun the risks of electrocuting the homeowner. Luckily enough that it’s easy to prevent and compared to other organic fuel burners, like the wood, it’s far safer.
Is a pellet stove cheaper than propane?
Yes, it is. Not only cheaper in terms of fuel cost, pellet stoves also take less operating and maintenance cost as well.
How much electricity does a pellet stove use?
It depends on the average price of a kilowatt in your living area and the stove capacity. To calculate the electrical cost to operate your pellet stove for 24 hours, follow this formula:
24 (hours) * The average price of a kilowatt in your living area (currency unit) * Stove capacity (kW)
My pellet stove is a Castle 12327 with the operating wattage of 77W or 0.077kW
The average price of a kilowatt in my living area is $0.08
ð The amount of electricity my pellet stove uses for 24 hours is 24 * 0.08 * 0.077 = $0.15 or 15 cents.
Can a pellet stove work without electricity?
Yes, it can.
Some pellet stoves are designed with gravity feeding system that uses no electricity to add pellets to the hopper. The operating process is like on a wood stove but way eco-friendlier and safer.
They are also usually EPA compliant as well.
How long will a 40 lb bag of wood pellets burn?
Usually within 24 hours (according to the Pellet Fuels Institute). But this number isn’t exactly all the time because it depends on the type of wood pellets you use for your stove. Pellets made from softwood will last longer a little bit than the hardwood.
Can a wood-burning stove be converted to a pellet stove?
Yes, it can.
Nowadays, there are many add-on versions of wood-burning stoves that you can easily convert to pellets. It just acquires you to buy a wood pellet basket insert for wood stoves.
However, the expensive extra cost has stopped many people from living an eco-friendlier life. So, if you’re looking for a cheaper alternative, consult this video:
Actually, considering a good position to place your pellet stove also optimizes its efficiency, if that’s what you are looking for. This depends on your home heating need – whether for an entire house or just some certain rooms.
Besides, be sure to check your own budget before picking one. Though this isn’t an extensive list of the options, I hope it’s a good start to help you choose the most efficient pellet stove for your own. Thanks for reading!
