The primary rationale for installing a wood stove insert rather than a stand-alone stove is to make use of an existing fireplace, but there are other advantages. A stove insert built into an existing brick or stone fireplace will undoubtedly be more efficient than a stand-alone device installed within the room. This is because the fireplace materials are insulating, provided the fireplace is an original element of the building. Keep in mind that better heat efficiency means cheaper heating expenditures.
There are several prerequisites for installing a wood stove insert, the most significant of which is a chimney. Without one, it is simply impossible. There are various types of chimneys, such as sound masonry chimneys or Stainless Steel Class "A" insulated chimneys, which are commonly used in new construction. We can presume that if a fireplace insert is being placed, the property already has a brick chimney, but this does not guarantee a safe and effective stove insert installation. There might be numerous issues with putting into an old chimney, such as the chimney needing to be lined, being too large or too tiny, or not being insulated. This emphasizes the importance of thorough preparation and planning before investing in a new wood stove insert, and the best suggestion would be to call a professional and have your chimney thoroughly inspected before spending any money.
Finally, even if you have an useable chimney, you will need proper floor protection behind your wood stove insert. This may not be the case if the fireplace has been empty, remodeled, or used for exhibition purposes. There are a few permitted materials for this purpose, such as concrete slabs, prefabricated Approved Stove Boards, ceramic tiles, or stone, but consult a specialist to ensure your fireplace meets the appropriate standards.
