As cold days approach, more and more people think of heating the house. If you plan to install a fireplace insert, this article is for you!
What is the difference between a closed fireplace and a fireplace insert
The difference between the two types of chimney consists mainly of the way of installation. The fireplace insert is intended to fit into an already existing fireplace without modifying the frame. However, a closed fireplace must be built. If you already have a traditional fireplace, it is recommended to opt for an insert. Moreover, its exploitation is much cheaper than the construction of a closed fireplace. And again, the insert requires a conduit and in some cases it will even provide additional casing.
The fireplace insert is an economic and ecological solution
What is a fireplace insert
A fireplace insert is a system that allows you to close your current home. It works from logs or pellets. It is a heating appliance designed to recover and diffuse a maximum of the heat resulting from the combustion of wood.
In this way it exceeds anyway the performance of the open fireplace. You may not have realized it, but with the traditional fireplace, you lose a lot of energy. This is because a large part of the heat produced escapes through the flue.
Important note : some models chimneys can not accommodate an insert, especially for size or configuration reasons.
The efficiency of an insert is 5 times higher than that of an open fireplace
A fireplace insert is designed with a double wall. The cold air comes from the bottom of the unit and heats up inside. Then he goes out into the room by the upper part. Between the outer wall and the inner wall also circulates a stream of air. It never comes into contact with ashes and fumes from burning wood. There are two sources of heat. The first is the circulation of hot air by convection and the second is the diffusion of the heat contained in the walls of the chimney by conduction. Mostly made of cast iron or steel, the insert also has a window that emits heat by thermal radiation.
In addition to the fireplace insert, you can install a distributor that distributes heat throughout the home through a ventilation system. However, be aware that this method requires more work and a large investment.
Warning : If you decide to install an insert, it is mandatory to call a professional. It will allow you to obtain a ten-year guarantee (with the guarantee of compatibility with the existing chimney), a reduced VAT, but also in some cases, the Eco PTZ and the tax credit.
In order to bring to an open fireplace the performance of a closed fireplace and keep the warm atmosphere of the flames, choose the wood insert
Advantages and disadvantages
- yield : While an open fireplace offers only 15% efficiency, an insert is able to restore between 70 and 80% of the heat generated by combustion
- Rather easy installation : we do not touch the structure of the already existing chimney
- security : fire hazards are limited as sparks and logs may fall in a fully enclosed fire
- Cleanliness : Ashes and dust remain inside the insert
- Autonomy : the fact that the combustion chamber is closed has a great impact on the autonomy of the installation (the approximate duration during which it is not necessary to add wood to maintain the production of heat)
- Cost : for the installation, you can benefit from a tax credit
- Atmosphere : An insert is less pleasant than an open hearth because the fire is no longer accessible
- Interview : you have to clean the window daily and collect the ashes
The insert is an economical solution thanks to the use of the cheapest fuels on the market
The criteria of choice
The efficiency of a chimney insert represents the amount of energy that is valued as heat in relation to the amount of energy contained in the fuel. If you want to use the insert as the primary heating mode, you must choose a model with the highest possible efficiency. The dimensions (the space available in the fireplace of your current chimney), the autonomy and the power (from 8 to 18 kW approximately) are the other criteria to take into account when choosing a fireplace insert.
Fireplace more efficient and more respectful of the environment
Logs or pellets
In general, there are two fuels that are most often used for inserts: logs and pellets (wood pellets). Logs are currently less expensive and produce beautiful flames, so the aesthetic effect is greater. On the other hand, they require you to refill the insert more often. Pellets are delivered in bulk or in bags, produce fewer flames and require much less concern because the tank of the device can store up to 15 kilos of fuel.
