How To Vent A Wood Stove Without A Chimney? 4 Important Factors To Consider

If your house has no chimney, you might be wondering how to vent a wood stove without a chimney? Is it possible? Yes, definitely. It’s just that some appropriate measures are needed to be taken to ensure safe installation. This can be done through a flue system called twin walls.

Although there are electric and gas stoves available, you might prefer burning solid fuel since an actual wood stove is cheaper, reliable, easy to find, and of course, real.

Imagine yourself, sitting near a stove just like in the movies. Isn’t it a pleasing scene? So read the entire guide to figure out a way to venting out a wood stove if you are living in a house with no chimney. We will include everything that you need to know through the entire installation process, so stay tuned!


Twin Wall Flue System

As mentioned earlier, the key to having a wood stove even without a chimney is the twin wall system. Essentially, this involves connectable piped that are made of stainless steel which will be carrying out the fumes of the stove. Those pipes are wrapped with thick insulation. Then, they are further encased with an outer tube that helps in keeping the temperature warm enough inside the flue to draw the fume from the steel pipes and then deposit it outside.


Factors That Affects How You Vent A Wood Stove Without A Chimney

How to vent a wood stove without a chimney? A lot of factors are to be considered to determine whether or not it is suitable in your space to accommodate the stove installation. Below is the list of the factors that play important roles to achieve this system.


#1. Flue

First of all, you have to consider if where will the flue exit in your place. You can either have it running internally that will simply look like the extension of your stove or you want it to run outside your place. This will greatly depend on the architectural structure of the house.

You can choose among the different parts such as the flashings, supports, bends, and lengths in connecting the wood stove into a safe point where the flue can exit the building. The recommended chimney height for a wood stove is at least 4.5 meters from the stovetop towards the chimney. Check the material of the termination point and figure out whether or not it is suitable for the flashing and flue kit fitting.

Brick, metal, and wood materials are the most ideal options. On the other hand, plastic and glass wouldn’t be ideal. For sure, you know why!

You might also wonder whether it is possible to install a wood stove in your conservatory. Yes, you can but this means that you will have to replace the glass section with a panel that is more appropriate so that the flue that will be exiting from there will be accommodated.


#2. Fireplace

When it comes to guarding the heat of the stove against the structure surrounding it, the main consideration should be safety. Particularly, if the material is flammable such as fabric or wood.

In such a case, you have to position the wood stove on a hearth that is not combustible. This can on a toughened glass or stone that is at least 12 mm thick. Ideally, this should also extend about 225 up to 300 mm towards the front of the door of your stove.


#3. Twin-wall flue

Now for the flue itself, it should include an insulated system with twin walls and not just a single flue pipe. The stainless steel construction of the two pipes is divided by an insulation layer. This will ensure that the outer wall will not get too hot to damage the structure surrounding or to hurt people touching it.

Since this is built into structures without a masonry chimney, the exposed flue can be run externally or internally, depending on what you prefer. When it comes to choosing a stove, you can select from the top and rear flue outlet to achieve the final look that you are after. And that is also applicable with air conditioners, especially when is the best time you should buy an air conditioner.


#3. Heatshield

You do not only need to protect the hearth, but you need to do the same with the vertical surfaces surrounding the unit against heat. With respect to installing a wood stove into an existing hearth opening, no minimum distance between the unit and its surrounding material is legally required.

This may be the case since masonry or brickwork are not combustible and they of not posed fire risks, unlike combustible materials. On the other hand, if you are to install a freestanding wood stove without a chimney, the distance of the unit from the surrounding combustible surface is needed to be considered.

The distance will depend on your stove model as well as its heat output. It is recommended that there is a distance of about 150 mm at any side and 75 mm at the back for the unit to effectively work.

You can buy non-combustible shields that you may position either at the sides or back of your stove for additional protection. Aside from reducing fire hazards, providing more space around the unit will allow the heat to be dispersed in the room better. Learn how to to build heat shields for your wood stove!


It’s A Wrap!

By considering the four factors above on how to vent a wood stove without a chimney, you will be able to enjoy the warmth provided by your wood-burning stove safely. During winter, your priority is to keep yourself warm, and when it’s time to sleep, it could be a challenge to stay warm with regular blankets, so does a heated blanket work? If so, you’d want to find out more about that!
