If you are a traditional type of person, then you’ll probably be a fan of wood burners, and you may even have thought about the possibility of fitting one in your summer house. The good news is that it is possible to install a wood burning stove in a shed or summer house, as long as you follow a few important guidelines to ensure your installation is safe, as well as aesthetically pleasing.

Wood burning stove in a shed

A shed log burner can create a beautiful focal point within a summerhouse, and it need not be a complicated process to install one.

The first thing to do before you get started is to work out what output of stove you need to heat your space. This should be a simple task, and your wood burner supplier will be able to assist in this respect. Once you have the right type of shed log burner, you can move on to the steps below.

Step 1: Choose the right position for your summerhouse wood burning stove

Ideally, you will need to site your wood burning stove so that the flue system goes straight upwards, without any bends. If you place the floor plate in position, you can then use a string line to work out the flue position and how it will pass through the roof.

You’ll need at least half a metre either side of the stove for safety, so bear this in mind when working out where to situate it.

Step 2: Fit your summerhouse log burner heat shield

All log burners need a heat shield to ensure the heat they produce does not damage the back wall of the summer house. You should find one supplied with your stove, and it will be made of heat resistant materials and clad in steel.

The heat shield lines up with the hearth plate, then screws to the wall. You can use your string line again to ensure the hole in the top of the stove aligns with where you’ve marked up for the flue outlet to go in the ceiling.

Step 3: Cut out your flue hole in the summerhouse roof

Whilst it can be slightly daunting cutting a hole in the roof of your summer house, it should fairly straightforward providing you follow the templates supplied with your shed log burner.

You already have your mark for the centre of the flue, so you can use the template to mark the hole. Pilot drill first with a spade bit, then use a jigsaw or reciprocating saw to cut all the way through the roof. The template should provide the appropriate clearances that are required around the flue system.

Step 4: Assemble your log burner and flue system

When fitting a wood burning stove in a shed or summer house, you will need to do a fair bit of measuring.

To assemble your log burner, place the first single wall flue in the stove. The junction of the two types of flue should be around 30cm below the roof. This is achieved by measuring and cutting the second single wall flue using a slitting disc and angle grinder.

Now remove the flue from the stove, and pack in some fire cement to create a seal within the hole. Push the flue back in. Now you can assemble what’s left of the flue, and push it up through the summer house roof.

Step 5: Install roof flashing

You will need to seal up the hole that was made in your summer house roof. There are various ways to do this, and it will depend upon what material your roof is made out of. Rubber flashing is one of the most popular choices as it is durable and lasts many years.

Once you have fitted your flashing, you are ready to cover it with the storm collar, and fit the cowl to the flue.

Step 6: Install a carbon monoxide detector

Whenever you have a shed log burner in a summer house, there is always a small risk related to the escape of carbon monoxide. So be sure to purchase a carbon monoxide detector and place it in the summerhouse in order to protect everyone.
