What Is The Most Efficient Pellet Stove For Heating In Winter

Many homeowners are nowadays interested in using pellet stoves because of many benefits. However, the main reason these units are growing in popularity over the last decade is efficiency.

The most efficient pellet stove can be up to 90% efficient than wood-burning stoves or an open fire. That means only 10% of the energy generated by the pellets is lost in the chimney.

Since many people have noticed how efficient these heating units are, manufacturers have continued to improve their pellet stoves every year. Today, you’ll find new models with higher heating efficiency than older models.

If you’re not sure how to choose a high-efficiency pellet stove, this guide is for you. I’ve reviewed a few models on the market to help you make an informed decision.

Pros and Cons of Pellet Stoves

Here are some of the most significant benefits of using a pellet stove for heating your home. The benefits are based on a comparison of pellet stoves with several other methods of heating a home, including conventional burners, electric or space heaters, and electric fireplaces.


  • High level of efficiency. The standard efficiency rate of pellet stoves is about 90%. Only 10% of the energy generated from the combustion process is lost in the chimney; the rest is successfully converted into heat energy. This efficiency rate is way higher than that of other alternative methods of heating homes. Traditional stoves have efficiency rates of about 50%.
  • Affordable fuel. Pellets are cheaper than other alternative fuels such as propane or even kerosene. A 40lb bag of pellets may cost about $5 which is lower than the price of alternatives.
  • Personalized heating. Pellet stoves have several settings for personalization, including built-in thermometers, and timers. You can program these features to make the time function according to your heating requirements. This helps to quickly create and maintain an excellent environment.


Here are a few important disadvantages of using pellet stoves

  • The built-in fan in many pellet stoves is quite noisy. The noise produced by pellet stoves may be loud enough to cause a distraction when two or more people are having a soft conversation in a room.
  • Pellet stoves require heavy maintenance for them to remain functional. This may include constant cleaning and removal of debris from compartments and other parts.

How Much Does It Cost to Run a Pellet Stove?

the most efficient wood stove installed in a cabinThere are two variable costs of running a pellet stove: electricity and fuel. For assumption purposes, let us calculate the cost of running a standard pellet stove for 24 hours.

The cost of electricity can be determined by multiplying the number of hours by the capacity of the stove in kW and the average price of electricity per kW.

If a pellet stove has an operating wattage of 75w, the cost of electricity required to run it will be 0.075kW by the price of electricity per kW by 24 hours.

The cost of fuel required to run a pellet stove can be determined by multiplying the amount of fuel by the number of hours. One 40lb bag of pellets can run a standard pellet stove for 24 hours. The average price of a 40lb bag of pellets is $5. Therefore, the cost of fuel for running a pellet stove is 24 hours by $5.

The total of these two variables is the cost of running a pellet stove. This can vary according to the total number of hours that the stove runs.

Is It Cheaper To Run a Pellet Stove or Natural Gas?

Running a pellet stove is cheaper than a natural gas heater or even the most efficient wood stove. Primarily, there is no much difference in the cost of buying and installing pellet stoves and natural gas heaters. However, the differences between these two modes of heating become clear when you consider other factors.

Although natural gas is sold in bulk, it costs much more than pellets. Pellets are made of recycled materials and are packaged in small bags that weigh 40lb. The extraction and preparation processes for natural gas are more advanced; therefore, the product costs more than pellets.

Furthermore, pellet stoves are more efficient than natural gas burners. Some pellet stoves have efficiency rates of 90%, while gas burners may have efficiency rates of 70%. Therefore, the high-efficiency rates of pellet stoves help to keep the costs of running them down.

Are Pellet Stoves More Efficient than Electric Heat?

It is important to look at the big picture to get the right answer to this question. Pellet stoves have efficiency rates indicated on their casing. This figure may be anywhere between 75% and 90%.

This means that the stoves can convert up to 90% of the energy from the combustion of the fuel into heat energy.

Electric heaters can have 100% conversion rates. This means that they convert all the electric energy that they take from the mains into heat energy.

However, it is important to consider other factors that affect the overall efficiency rates of these two heating systems. Electric heaters use electricity which is produced from other sources.

The average efficiency of the production of electric power is 30%. Stoves use pellets that are manufactured from waste products, including sawdust.

When you factor in these other issues, then the efficiency rate of pellet stoves is higher than that of electric heaters.

Can a Pellet Stove Heat a Whole House?

can the most efficient wood stove heat a whole house

To determine whether a pellet stove can be used to heat the whole house, it is necessary to consider how it works, the heating area, and other related factors. The heating requirements of a house are determined by many things, including the prevailing weather conditions, season, and space.

You will require a lot of heat during cold times of the day or night than the warm ones. Also, a lot of heating is needed during the wintry weather than the warm seasons. Additionally, the space of the house determines the amount of heating energy required for warmth.

Large houses need more energy than small ones. Also, houses with high ceilings require additional heating energy than those with normal ceiling heights because high-ceiling rooms have more space in the living zone than normal or low-ceiling rooms.

The mode of operation of a pellet stove is strong and effective enough to warm an entire house. A pellet stove draws in air through the pipes and chambers that are located in the firebox. The cool air is usually drawn from near the floor of the room in which the stove is installed.

Through the combustion of pellets, the cool air is effectively heated. Thereafter, it is forced out through a small fan into the living space in the room. Because of the effect of the fan, pellet stoves have high heating capacities. Some stoves can effectively warm spaces that are as big as 2,000 square space.

Also, some pellet stoves can be easily moved from one place to another. They can be used to heat one room after another because of their high level of portability and low running costs. Therefore, it is practical to use a pellet stove to heat the entire house.

How Long Will a 40 lb Bag of Pellets Burn?

A 40lb bag of pellets can burn for 24 hours. Some pellet stoves have large hopper spaces that can take as much as 50lb of pellets. Others have small hoppers that take only 20lb of pellets at a time.

When using pellet stoves that have small hoppers, you will have to refill them more frequently than when you are using stoves that have large hoppers.

Typically, you may need about a ton of pellets per year to keep your pellet stove burning for most of the time. You may need this amount of fuel if you use the pellet stove to heat the entire house.

The good news is that pellet prices are quite low. A 40lb bag of pellets costs only $5. Therefore, you will be spending only $5 per day on pellets to keep the stove burning round the clock.

Can I Leave My Pellet Stove On All Night?

can you leave pellets stoves on all nightYes, you can leave your pellet stove on all night. Pellet stoves have been designed to run on a 24/7 basis. This means that you only need to switch it off when you need to perform routine cleaning and maintenance procedures. Otherwise, the pellet stove serves you well when let to run nonstop.

It is strongly recommended that you switch off your conventional electric heaters during the night because of the high level of danger that the devices pose when left unattended.

Electric heaters can easily cause fire accidents if they get into contact with highly combustible materials, including plastics, fabric, and paper. Similarly, electric heaters can cause fires if they get accidentally knocked to the floor.

Pellet stoves are more secure than electric heaters. The level of risk of electrocution is drastically reduced in pellet stoves compared to electric heaters. This is because pellet stoves use very little current for secondary processes as opposed to electric space heaters that convert electric energy into heat energy.

Moreover, people switch off their space heaters at night as a way of keeping the costs of heating their homes low. It is quite expensive to operate a typical space heater that converts electric energy into heat energy.

Pellet stoves, on the other hand, are affordable because they use cheap-priced pellets. Therefore, leaving your pellet stove on for the entire night will not have a significant change in the total costs of heating the home.

Will a Pellet Stove Increase Homeowners’ Insurance?

A pellet stove can increase your homeowner’s insurance. The presence of a pellet stove in a house considerably increases the risk of fire outbreaks. Because homeowner’s insurance plans cover against risks such as fire outbreaks, having a pellet stove installed in a house is likely to increase the level of the risk covered.

As a result, the number of premiums paid under plans for covering houses that have pellet stoves is higher than those for houses that do not have pellet stoves.

When either buying a house that already has a pellet stove or installing a new device in your home, ensure that you notify your insurance company. The insurance company will conduct a few processes to ensure that all administrative hurdles associated with covering a house with an enhanced fire risk are ironed out.

The company will check that the installation is done by a certified technician. This step helps to prevent the occurrence of a dispute between you and the insurance cover if your house catches fire and the company realizes that the installation was not done by a certified person.

Also, the insurance company will check if the installation is done according to the relevant local fire codes. This still will help to prevent disputes in the event of a fire.
