Outdoor Air Intakes

Do I need to connect an outside air intake to my Stûv wood-burning appliance? Good question! Read on to better understand the purpose an outside air intake serves and if one is necessary for your project.

What exactly is an outside air intake and what does it do?

A fire needs oxygen to burn. An outside air intake is a flexible pipe, four to six inches in diameter, that supplies your stove or fireplace with air without taking it from inside your home.

How do I know if I need an outside air intake?

Here are a few situations in which connecting an outside air intake will help your appliance run optimally:

  • •Type of building

Some buildings, such as newly built passive homes, may require that a wood-burning stove or fireplace be directly connected to an outside air intake. This is so the air supply available inside the residence is not affected. It’s important to know your building’s construction parameters before installing such an appliance.

  • •Room’s surface area

When choosing a wood-burning stove or fireplace, it’s important to take into consideration the surface area of the room in which it will be installed. Even if you connect your Stûv appliance to an outside air intake, a stove or fireplace that is not the right size for the room will not have optimal combustion. Our network of certified experts can help you choose the ideal model for your needs.

  • •Different ventilation systems in the home

Different ventilation systems can also affect air supply to your appliance. One example is range hoods, which are increasingly powerful. When you are lighting a fire or adding wood to your stove or fireplace, a range hood can create negative air pressure in your home, causing smoke to backflow into the room.

  • •Municipal bylaws

Some municipalities require the installation of an outside air intake. Check with your local authorities.

What problems can be avoided by installing an outside air intake?

A Stûv wood-burning appliance that is not connected to an outside air intake may not burn efficiently and can cause unwanted effects during use:

    • •Backdraft smoke from the chimney;
    • •Low combustion and small flames;
    • •Blackened combustion chamber;
    • •Darkened glass

When should I install an outside air intake?

Although you can install an outside air intake after you’ve already begun using your Stûv stove or fireplace, we recommend installing it in the early stages of your project. It will be much simpler and cheaper.

In conclusion, connecting an outside air intake to your Stûv wood-burning stove or fireplace is strongly recommended. It will optimize your appliance’s combustion while preventing unpleasant effects, such as smoke backflow. Our extensive network of certified specialists can help you with your project and properly assess your outside air-supply needs to maximize your new Stûv’s efficiency.

How to Choose the Right Wood-Burning Appliance

Whether you’re building a new home, doing renovations, or are thinking of replacing your stove or fireplace, selecting a new heating unit can feel overwhelming. How to choose from the many options available? In this article, Stûv explains some key factors that will help narrow down your choice.

What is the difference between a wood stove and a fireplace?

First, it is important to determine the type of heating appliance that will best suit your home. There are two broad categories of wood-burning appliances: stoves and fireplaces. The difference lies in their installation.

Fireplaces and inserts

Fireplaces and inserts are installed in an existing wall or a chimney body. If you have a masonry hearth, you will need an insert that fits perfectly into your chimney. If you don’t have a masonry hearth, you can opt for a wall installation with a zero-clearance fireplace that meets your needs. Note that both fireplaces and inserts need a finish, which you can customize for an aesthetically pleasing result.

Wood stoves

Stoves are independent heating units that do not require finishing materials. Since they can be installed on the floor or on a podium, Stûv wood-burning stoves are easy to add to your home.

Where would you like to install your Stûv?

Now that you know the difference between a stove, a fireplace and an insert, you can decide which type of appliance will suit your home. If you plan to install your fireplace in a masonry hearth, you will need an insert.

Masonry hearths are mainly found in homes built before the 1970s. If you don’t have a hearth, you can have a zero-clearance Stûv fireplace built right into the wall.

Due to their insulated shell, zero-clearance wood-burning fireplaces let you safely place combustible materials next to the fireplace.
If your plans do not include a wall unit, opt for a wood-burning stove. Available in different shapes and sizes, Stûv wood-burning stoves will enhance any room.

Whether you plan to install it along a wall, in a corner or in the middle of the room, Stûv wood stoves are remarkably versatile.

Or get the best of both worlds! Stuv’s unique freestanding fireplace sets it apart from the competition.

Stûv 21-clad does not need any finishing and is the only certified fireplace in North America with an exposed insulated chimney.

Things to consider

So you’ve chosen the location of your new stove or fireplace but aren’t sure which model would be best? Here are some key aspects you’ll want to keep in mind.

Surface area you want to heat
To choose the most suitable unit, you will need to determine your heating needs. Every stove and fireplace has its own heat index, depending on the size of its combustion chamber and its glass pane, and its maximum heating capacity is indicated in BTUs. You will find the surface area that Stûv appliances cover on their respective web pages, in the Technical Documents section.

Understanding BTUs

Type of construction
Another aspect that is often overlooked is your current or future home’s construction. The performance of a wood stove or fireplace depends on its environment. Stûv units will perform differently according to several factors, including how long ago the home was built, its airtightness and shape.

Of course, you probably want your new Stûv stove or fireplace to suit your decor. Depending on the size, shape and layout of the room, the sleek design of Stûv’s heating appliances will add a unique and timeless touch.
