Fireplace dimensions


Few things contribute to creating an atmosphere of comfort in a private house, like a real fireplace. With seeming simplicity, it can be quite difficult to build it with your own hands, as the fireplace is a complex heating device and there are many nuances in its installation, ranging from the installation of the foundation, the choice of the firebox, the material of the box and the choice of design and shape of the chimney.

The main thing in this case is to correctly determine the need for heating the room, and on the basis of these data, select the appropriate size of the fireplace.

So, for rooms of 20 and 40 square meters, a fireplace with a base of 150 * 90 cm is suitable, for a larger area a large fireplace is needed. It is worth remembering that a modern fireplace based on a cast-iron firebox with a convection duct is much more efficient for heating than old brick fireplaces with an open firebox.

Let's look at the main types of fireplaces available for selection:


Decorative or false fireplace is an excellent find for the interior. You can easily do it yourself and install it even in a small room. You can create such an imitation from a variety of, even “junk” materials.

However, it must be remembered that the installation of such a fireplace has significant limitations, primarily related to the material and the thickness of the wall and the design of the chimney. Typically, such fireplaces should be provided at the design stage of the house, thus avoiding installation problems.

This design allows you to keep warm up to 18 hours after the extinction of the flame.

Dimensions of the furnace

When choosing the size of the furnace must proceed from two characteristics - the size of the heated room and financial opportunities. The standard dimensions of the furnaces in the table increase with a step of 10 centimeters, and depend on the shape of the furnace, while their price also increases nonlinearly.We should not think that the largest fireplace - the best, heated space and a fireplace should be proportionate.

The size of the box should be chosen according to the size of the firebox. An important factor is whether the fireplace was provided for in the project of the house and whether there is a place for it on the floor plan. If space was provided, the choice of firebox and installation are not particularly difficult. If not, it is recommended to consult with qualified installers, who will advise you on installing and choosing a place under the fireplace, at the first stage before choosing a fireplace.

When the fireplace was not originally provided, problems often arise during installation - with the bearing capacity of the floors, the orientation of the fireplace, the withdrawal of the chimney with a complex bypass of the supporting building structures.

You should also not forget that you can not arrange stretch ceilings directly above the fireplace. When designing a fireplace and selecting a firebox, you need to remember that a fireplace is not only a firebox, but also a firebox (usually for a standard log size), a place for a scoop, and a shelf.

It is worth noting that a modern fireplace based on the firebox and convection duct takes up much less space.than a classic fireplace from an open-hearth masonry, as many structural elements, such as hilo and a tooth, are already made inside the firebox. In addition, due to the convection duct with heat holes, a modern fireplace heats the room much faster and more efficiently, as well as much easier and faster to manufacture.

Dimensions and material

The overall dimensions of the entire fireplace depend on the selected firebox, the size of the convection duct and the material of its manufacture. So, a brick box is more monumental, reliable, but takes up more space. Also, the box can be made of gas blocks, pews, or plasterboard, you should only remember that it is undesirable to make them from combustible materials, such as wood, chipboard, plywood.

It should also be remembered that the fireplace is a heating device and in its design it is necessary to adhere to state building standards and manufacturer's recommendations.

Recommended dimensions of the convection duct can be found in the instructions for the selected firebox. The most important thing is to keep the minimum dimensions so that the air inside the box does not overheat, but when it heats up evenly, it leaves through the ventilation duct grilles.It is also necessary to leave a ventilation gap above the fireplace door. Determining the size of the fireplace in each case individually, and depends on the diameter of the pipe, the number of air channels and aesthetic feasibility.
