Deciding on installing a wood burning stove

When having a wood burning stove installed, there may be one or two considerations to take into account.

Do I have a suitable chimney stack built into the house, can I have a stove without one and is the fireplace large enough to take the stove I want.

 Existing internal chimney stack

Where a house already has a traditional built in chimney stack, the procedure for installing a stove, is generally straight forward. After an inspection of the chimney flue to check for it’s internal condition, the flue will be swept in preparation for the liner.

House without a built in chimney stack

If there is no chimney stack already in the building, a twin walled exterior flue is a  alternative option, with the stack running on the outside of the building. Firstly a hole is bored through the outer wall to gain access to the room.


The water cooled diamond core drill will cut a hole at 45 degrees through the cavity wall,
into the room where the stove is to be sited.

The new opening is then lined with a stainless steel sleeve, ready to take the twin wall pipe.


Next comes the installation of the twin walled pipe system, which attaches to the side of the house with various supports and brackets. This pipework is available in either a Stainless steel finish or powder coated black and will finish above the roof ridge.

This following example is again an exterior twin walled system, but this time having the hearth built on the outside of the house, so the stove does not intrude into the room, taking up vitally required space.

Fireplace place opening and Hearth

If an existing fire place is not large enough, the chimney breast will need to be opened up to accommodate the chosen height of the stove.
