What Is A Pellet Stove And How Does It Work?
Pellet stoves work very differently to other heaters that are commonly used to warm up our homes. Below is a summary of how a pellet stove works, just past the text is an image that shows the main components of a pellet heater.
- Pellets of compressed biomass material (usually made of wood or corn) are loaded into the hopper. The amount of pellets that a hopper can hold varies, but it is generally from 40 lbs (18 kg’s) up to over 100 lbs (45 kg’s).
- An auger, which is driven by an electric motor, turns and carries pellets from the hopper to the burn pot. Sensors within the stove tell the system when to turn the augur to add more fuel depending on the heat setting.
- The pellets are added to the burn pot. The fire is kept very small, but very hot. This way the pellet stove burns at maximum efficiency with very little waste.
- An electric blower adds air to the fire to help the pellets burn as efficiently and as hot as possible. Used air is then vented, the type of venting depends on the model of pellet stove.
- Above the heating compartment is a heat exchanger, this is usually a series of pipes that catch almost all the heat from within the stove. Depending on the model, a fan may be used to disperse the heat.
Benefits of a Pellet Stove
Apart from the obvious benefits of keeping you warm, there are many other reasons that pellet stoves should be high on your list of possible heating options. We have listed just a few of the very best reasons below to really get you thinking!
Control Your Heating Costs
We all hate getting the heating bill at the end of winter, not knowing what it will be or how much to budget for can be stressful. Not to mention that energy prices for gas, electricity and oil goes up and down constantly – which makes it even harder to manage the heating budget.
One of the benefits of pellet stoves is that because you control when you buy the fuel, you can control your heating costs for the entire heating season. You can shop around for the best fuel pellet deals before it starts to get cold, and order a bulk amount that will get you through the colder months. This way, you pay for your heating costs up front and there won’t be any nasty surprises in the mail when the weather starts to warm up.
Fuel pellets are also much more economical than most other methods of heating, so you can keep your heating costs down and take total control of your heating costs.
Better For The Environment
Pellet heaters use fuel that are often created from waste materials, off cuts and sawdust – so you are utilizing recycled products that would have otherwise gone to waste. Pellet stoves also burn much more efficiently and produce much less wood smoke than any other solid fuel burning heater, thus they put out far less harmful emissions into the environment.
Automated Heating
Pellet stoves are basically a set and forget heater for the day. All you need to do is fill the hopper with fuel pellets, set the desired heat setting and that’s it. Your Pellet heater then automatically loads more pellets into the burn pot at the pre-set rate, keeping your home comfortably warm for the entire day.
Radiant Convection Heat
Everyone loves a good wood fire right? There is nothing like sitting near the fireplace and soaking up the warmth, the only problem is constantly having to fill it with wood fuel! Well with a pellet stove, you can have the same warming, radiant convection heat, without the need to be constantly loading it up with wood.Easy To Maintain
Maintaining a pellet heater is quick and easy. Go straight to our pellet heater maintenance section to learn more.
Safe to Use
When compared to a wood stove, pellet stoves are certainly the safer alternative. The following safety features are in most pellet stoves:
- Automatic shutdown – monitors burn rate and temperature for unusual conditions and shuts the stove down if necessary
- Pressure switch – automatically shuts the feed motor off if the front door or the ash door is open. Also detects when the venting system is not working correctly.
- Exhaust sensing probe – shuts down when abnormally high temperatures are detected
Important Installation Note
It should be noted here that you have your pellet stove installed by a professional installer to ensure you and your family are as safe as possible.The Best Pellet Stoves

Pellet Stove Buying Guide
So you have made the decision to invest in a pellet heater, now you just need to decide which pellet heater is best for you. Not all pellet stoves are created equal – each stove brand and type is designed for it different situations, so it is important that you carefully consider your options and make a decision that is right for your home.
The following sections are areas we recommend you pay special attention to when choosing a pellet stove to suit your requirements.
Heating Output and Efficiency
When shopping for a pellet stove, one of the first numbers you will have thrown at you be every salesman is the term BTU rating.
But what does that even mean?
What is a BTU Rating
BTU stands for British Thermal Units and it is used to measure heat output. 1 BTU is the amount of heat required to increase the temperature of one pound of water by one degree Fahrenheit.
Now I know this sounds complicated, but you don;t really need to get into the nitty gritty of how the BTU measurement works. What you do need to know is this:
The specifications or salesperson may quote one, or both of the possible BTU measurements:
- BTU input
- BTU output
Firstly, you need to understand that most premium wood fuel pellets contain about 8,500 BTU per pound.
The BTU input is the maximum amount of fuel that can be fed into the pellet stove per hour.
The BTU output is how much heat the stove can actually deliver to the home, the rest is lost to inefficiencies in burning, heat transfer, up the chimney/venting etc.
Heating Efficiency
So now that we understand what a BTU rating is, we can then understand the next number that is often quoted to us – the pellet stoves efficiency.
Efficiency% = (input BTU/output BTU) * 100
This gives us our efficiency as a percentage. This number tells us how much of the heat that is generated in the pellet heater is actually usable in the home.
The higher the efficiency, the more cost effective your heater will be to run.
Pellet Type
While pellets are reasonably easy to find, it is important that you know which pellet types are best for your heater. You can learn more about fuel pellets and the different types available here.
Maintenance Required
While pellet stoves are considered to be reasonably low maintenance, they do require you a few periodic maintenance tasks to be carried out . You will need to shut your stove down regularly (weekly is preferable) and clean out all the soot from the burn pot, this won’t take you long as there won’t be a lot of soot to clean because they burn so cleanly; but just a little bit of built up soot in your pellet stove can lead to quite a large drop in efficiency.
Each model of pellet stove will have its own maintenance guidelines in the manual, so be sure to check these out before deciding if a particular heater is right for you.

Style and Placement of Stove
There are two basic types of pellet stoves:
- Free standing pellet stove
- Pellet insert
If you have an existing fireplace, then you can most likely use a pellet insert that fits into the existing fireplace and chimney. The U.S Department of Energy (DOE) strongly recommends that before you fit a pellet insert, you should have a professional installer carry out an inspection on your fireplace and chimney to check for suitability and safety requirements.
Choosing where to locate your pellet stove is vert important. Before deciding on which stove you are going to buy, get a hold of the manual and make sure that you can meet the space requirements.
The manual usually lists the minimum space allowed between the stove and certain combustible materials.
Electricity Requirements
Pellet stoves do require a constant electricity source to operate, so be sure to consider where your nearest power outlet is in relation to where the stove is likely to be fitted.
Hot Tip!
If you lose power to the pellet stove, then it will stop operating – which obviously results in losing all your heating. To get around this, it is possible to use a computer uninterruptible power supply to provide backup power the stove for up to 1 hour to get you through those black outs!Ask a Professional
One of the biggest traps consumers fall into when buying a pellet heater, is not getting a a professional to take a look at the area to be heated before making a decision. A consumer may under or over shoot the heating needs and buy a stove that is too small or too large for their needs. Home size, layout (open vs many rooms), and home insulation all play an important part of choosing the right pellet stove.
Pellet Fuel Guide
When it comes to choosing a pellet brand and type to choose, it is certainly not a case of apples for apples. It is important that you weigh up each brand of pellet fuel and carefully consider your options.
Fuel Pellet Grades
Pellet fuel generally comes in two grades:
- Premium grade pellets
- Standard grade pellets
Premium pellets contain a lower percentage of inorganic ash content (<1%), this results in less soot being produced by the burning of fuel, which in turn leads to less maintenance.
Standard grade fuel pellets burn slightly less efficiently due to the higher ash content (generally between 1-5%).
Premium Pellets Are Best!
We highly recommend spending the bit extra and getting premium grade wood pellets. They will burn more efficiently and result in less soot build up in your stove.What Are Fuel Pellets Made From?
Beyond the grades of fuel pellets, the next consideration should be what the pellets are made from. The main materials that pellets are made from are:
- Hardwood
- Softwood
- Corn
Most modern pellet stoves will burn both hardwood and softwood pellets with very similar efficiency. It should be noted though that while softwood pellets are usually more expensive, you do get a higher heat from them. More heat = less pellets required to heat your home and less ash and soot build up in your pellet stove.
Fuel pellets made from corn are far less common, can can be a viable alternative to pellets made from wood and have the added benefit of being a renewable resource. Corn pellets produce about the same amount of heat as wood pellets, but they have a higher ash content which means more maintenance. Corn pellets are generally cheaper than wood pellets, but it does depends on where you live.
Burning corn pellets is usually best done in a pellet stove designed for that purpose, however you can usually use corn pellets mixed in with standard wood pellets without any problem in a standard pellet stove.
Storing Fuel Pellets
It is also worth mentioning that you may need considerable storage space to keep your fuel pellets.
Fuel pellets generally come in 40-50lb bags, so keep in mind that you will need somewhere dry to store pellet bags, especially if you live in a remote area. On a cold winter you may go through as much as two pellet bags per day!Making Your Own Fuel Pellets
Making your own is possible but can lead to problems if the pellets are not made correctly. The home made pellets may crumble and get stuck in the chute, causing efficiency problems or possibly causing the heater to stop working all together. In our opinion, making your own fuel pellets is generally not worth it and going for the store bought option is a much better choice.
Pellet Stove Maintenance
As with any device that involves heat and electricity, it is important to keep your pellet stove properly maintained. This not only ensures that your pellet heater runs as efficiently as possible, following the maintenance guidelines for your stove means your heater will be as safe as any heater can be.
Maintenance tasks required vary for each model, but we have written up a summary of general maintenance tasks that are required with most pellet stoves below.
Daily maintenance tasks:
- Pellet hopper: Check it is clear of any accumulated saw dust and top up it up to ensure you don’t run out of fuel just when you need it the most.
- Burn Pot: Check the burn pot daily to ensure the air inlets look clear and open.
Weekly maintenance tasks:
- Ash pan: empty all the ash that the ash pan has caught. This usually has to to done 1-2 times a week although some newer designs can go as long as a month without requiring emptying.
Periodic maintenance tasks:
- Burn pot: Clean the burn pot as you notice soot build up.
- Ash trap: Ash traps help to stop flying ash exiting the stove via the vent, these require cleaning to ensure your pellet stove can burn efficiently.
- Glass: Clean the glass to prevent a build up of soot, the longer you leave it between cleans the harder it will be to remove the soot.
- Heat exchanger: This needs to be cleaned, some models include a device to let you clean this yourself, other models may require a professional.
Annual tasks:
- As with any heating appliance, we recommend getting your pellet stove checked by a professional every 12 months to ensure it is operating safely and within efficiency parameters
