The insert

The insert fits into an already existing fireplace: it transforms an open hearth fireplace into a closed hearth fireplace. The heat output is strongly affected, going from an average of 15% to 75%. The advantage of the insert is that it considerably minimizes the work to be carried out. To install it, it is necessary that the flue is in good condition. Be sure to have it checked by a professional. For safety reasons, the casing of the conduit is necessary. On the heating side, low front entrances are installed to capture the ambient air. The latter is returned to the room in the upper part, generally through grids. The glass also captures heat by reverberation.

The closed hearth

Unlike the insert, the closed hearth is installed during the complete assembly of a chimney. The air in the room is drawn in from the bottom of the fireplace and exits through the hood. Like the insert, the closed hearth has a window which acts by reverberation to restore the heat. To increase the performance of the closed hearth, it is even possible to install ducts. These will spread the heat to the other rooms of the house. The closed fireplace is therefore an ideal solution if you want to make it your main heating mode. In short, if you already have an open fireplace, the best solution obviously remains to opt for an insert.

Advantages and disadvantages of the insert and the closed hearth

Both economical and ecological, wood combustion is reduced compared to an open fireplace. The heat output is optimized and the autonomy is 5 times greater than with an open hearth. On average, it is 10 hours. The glass placed in front of the fireplace provides security in the event of flying embers. On the design side, it is possible to customize the fireplace frame as desired to give character to your living room. The disadvantages are less, but they must be taken into account when purchasing. The insert and the closed hearth are less visually pleasing than an open hearth fireplace. However, they have undeniable charm and in view of the advantages, it is rather easy to make this small compromise. Second drawback: the glass tends to clog easily. This requires regular and rigorous maintenance.
