What is a Pellet Stove Insert and Why Should You Buy It?

A pellet stove insert is a legless pellet stove that burns compressed wood to create heat for not only residential spaces but also industrial ones.

Unlike free-standing models that stand on legs, a pellet stove insert is made to fit inside a fireplace opening. If you are looking for a low-operational cost, eco-friendly fireplace that can efficiently heat up your room, then a pellet stove insert is the one to go for.

What Should You Know about Pellet Stoves?

Throughout history, wood has always been used as a source for creating heat. Professional wood-fired ovens were even used in the early 20th century but in 1930, the Presto-Log was invented. It reused scrap sawdust for domestic heat and got quite popular back in the day. As time passed by, the miniaturized pellet stove was invented in the 1980s in Washington.

The 1973 oil crisis made people realize the importance of renewable sources of energy, which finally led to the creation of the first pellet stoves. There are two main types of pellet stoves – the free-standing ones and the fireplace inserts which are vented into chimneys. Most pellet stoves are made using steel or cast iron pieces along with stainless steel for efficient heat production.

Today, there is a huge demand for biomass stoves and combustible renewable sources for producing both domestic and industrial heat. Over the years, the design of the pellet stove has changed from a basic boxy one to the pellet stove inserts we see today.

What are the Differences Between a Pellet Stove and a Pellet Stove Insert?

Here are some ways in which pellet stove inserts are different from normal pellet stoves.

Form – Pellet Stove inserts are designed to fit into fireplaces, which is different from a pellet stove which comes with a pedestal or legs.

Installation – As a pellet stove insert is completely different in form than a pellet stove, their installation is quite different and depends on different factors.

Venting – Pellet stove inserts utilize a more flexible liner system when getting installed into a fireplace. When they are installed into a framed opening, it needs to use rigid venting. These liners connect to the back of the stove and go up the chimney. The rigid venting has to be routed through the roof.

Fuel System – Pellet stoves can either use electricity or a gravity-fed fuel system, but pellet inserts can only utilize electricity due to its height limitations.

What are the Benefits of a Pellet Stove Insert?

Better Control – Depending on the model you buy, you will be able to adjust the temperature more conveniently with remote control. Some of them can even be programmed to operate at a set time through your mobile. When the preset time comes, the stove will start and turn off automatically without you doing anything.

Better Efficiency – Pellet stove inserts are known for their high efficiency when it comes to heat production. Only 10 percent of the energy generated is lost, which makes it better than a classic wood burning stove or an open fire.

Effective Ash Removal – It comes with an ashtray that effectively removes ash when compared to wood burning models.

Less Work – You only have to manually fill the stove once or twice a day. Once it is done, it will last up to 12 hours easily.

More Affordable in the Long Run – Pellets are more affordable than other fuels with no spike in prices over the last few years. They usually come in bags of 40 lbs and can be stored pretty easily. One pellet stove can hold up to 1.5 to 2.5 bags of pellet at a time. The amount of fuel it consumes depends on the size of the room you want to heat up and the insulation.

Things to Know Before Buying a Pellet Stove Insert

Weekly Maintenance – Apart from mandatory yearly inspections by a professional, it is very important that you clean it at least once a week. The ignition chamber, in particular, has to be vacuumed once a week to ensure the longevity of the stove and maintain its efficiency.

Only Vertical Venting – A pellet stove insert is limited to only vertical venting, which can be a disadvantage at times.

Cost of Running – You need a 120-volt power supply to run the pellet stove insert.

Unnatural Flame – The flames created by a pellet stove insert don’t have the same look as a natural flame, which may put off some people.

Dry Storage for Pellets – Unlike gas, you need sufficient space to store your pellet bags. You also need to make sure that the storage area remains dry at all times. Otherwise, the pellets may swell or split open, making them unusable.

Before you decide to go off and buy a pellet stove insert, make sure you do your due diligence and plan appropriately.

Installation Costs

The cost of a pellet stove insert installation can change depending on several factors like size and vent work required. On average, the cost ranges from $1000 to $2000, but it can go up to $4000 as well. If you require a new liner or if you need to have a power outlet fixed in your fireplace, the cost of installation may go up.

You might feel that installing it yourself is a more affordable option, but it would be wiser to let a professional handle it. Not only will it be safer, but it will also make sure that your stove will run for a longer time.

Commonly Asked Questions about Pellet Stove Inserts

How long will it last?

With good and regular maintenance, it can last up to 15 to 20 years.

What will be its running cost per month?

The cost will depend purely on your usage. A 40 lbs bag of pellets can last up to a full day, which may cost anywhere between $4 and $6. On top of that, you will also have to bear the electricity cost which will vary from one location to another.

What about Insurance?

These stoves can be seen as a major cause of fires, mostly during the winter. If you get one, make sure you talk to your homeowner and insurance agent to get an estimate on changes in policy rates.

How much energy will it save?

With a pellet stove insert, you will be able to reduce your heating costs by 10% to 40%. As it comes with an enclosed design, more heat is extracted at a lesser overall cost.
