Fireplace with air heating

Fireplace is a sign of noble taste in the interior, it is a symbol of comfort and warmth. Today, the man who decided to install a fireplace has plenty to choose from. The range is quite wide. In order for this element of the decor not only to please the eye, but also to heat the room well, it’s better to stop your choice on the fireplace with the firebox closed. There are two types of such models: with air heating and water.

Advantages and disadvantages

The device of a fireplace with air heating will help to keep warm. The function of such a device is double: interior decoration, decor element and space heating. Fuel consumption in fireplaces with a closed firebox is quite economical. Fireplace with air heating will warm the house and save money.

The complexity of this design lies in the fact that its design must be made when building a house. So it will work as efficiently as possible.A humidifier in a house with air heating is not required. After all, with the help of convection, you can optionally increase or decrease the humidity of the air. This will create a comfortable climate in the house.

Among the shortcomings can be identified the need to constantly monitor the presence of firewood in the furnace. It is necessary to periodically clean the chimney, clean the ash. It will require a place to store fuel for the fireplace.

Device and design

A fireplace with an air heating system is much cheaper than its counterpart with a contour on water. The adaptation of such a device to the particular features of a particular house will require a lot of effort, but as a result, it will save on fuel consumption and room heating. Heat exchangers, special extra pipes in the design, will help reduce fuel consumption.

The design of this fireplace allows you to heat the air from the flame. This is facilitated by the presence of channels that are located between the outer walls and the firebox. The pipe that goes through the air is isolated. Warm air enters the room through a special hole. Smoke goes through another channel that has access to the chimney.

A project of this design should be included in the drawings of the house and the fireplace. Cold air through a separate hole enters the pipe, it heats up, rises and exits through the grate under the ceiling. To warm more space, it is necessary to additionally install a fan. It will help the air circulate and heat faster. A fireplace with an external air intake is inconvenient because the air flow can be stale and carry dust.

Tray for collecting soot should be equipped at the top of the furnace, since that is where it accumulates the most. Remove the dirt will allow a special door. The filter will help clean the intake air directly from contamination. It is mounted in the valves in front of the fireplace. Installing an ionizer is another way to get rid of dust.

Principle of operation

Dual heat transfer is the main feature of the fireplace with a water circuit; this is how it differs from air heating. The scheme of the heating process with the circulation of warm and cold air looks quite simple. The supply of cold air provides the flow of fluids into the fireplace through the pipes. The flow should be constant for high-quality heating; air intake occurs from the street or from the rooms. For this purpose, a fence system leaves the subfield.

Additional air supply can provide a fan. It is installed in the vent of the fireplace. This device allows you to increase the rate of air circulation in the system. The streams pass through the pipes, get to the hearth, heat up, flow into the walls, the insulation box and the chimney. When enough warm air is collected, it enters the rooms through the ventilation grilles.

It assembles and distributes the warm air of the fireplace with air heating. This is one of the most important parts of the structure together with the duct system. Air humidification in the house will be of high quality when the system is working properly. External air supply from the street is due to the fact that dust and small particles get inside, therefore regular cleaning of the gratings is mandatory.

Smoke evacuation channels are involved in the removal of combustion products. They are equipped with any fireplaces. Ventilation routing is the main design in the air heating system. Quality of heating of the room depends on it.

How to choose

When choosing a conventional fireplace, we focus on the ratio of the area of ​​the room and the power of the firebox.In the case of an air heating system, a too powerful firebox will lead to constant overheating of the air. It will be necessary to monitor the level of fire, the amount of firewood, and regularly ventilate the room.

In order not to be mistaken with the choice of the firebox, it is necessary to take into account the area, and also the number of rooms in the house, floors, windows, features of the ventilation system.

Installation rules

When installing and operating a fireplace with air heating, you should remember certain rules for the components of this design. Insulating air ducts reduces heat loss and noise levels. The material used is brick, metal; flexible pipes are suitable for small spaces. A channel filter will reduce dust and dirt. It is important to clean the system regularly.

When installing the duct should be well fixed. You should not make it narrow, it will affect noise insulation. Poor sealing of the structure airs the system when melting, air plugs are formed. At the same time, the quality of heating is sharply reduced. To cope with traffic will help a special automatic air valve for heating.


Drawings of the hearth need to be developed with specialists, as there are many nuances in designing a fireplace with air heating. Care must be taken to ensure that air flows in the right direction, there is no loss of air during the heating process. For this, the design of the box, pipes and chimney must be completely sealed. All this should be taken care of at the stage of building a house. The location of the ventilation holes will have to be thought out, in the walls to lay the pipes connecting the rooms.

In order for the fireplace to more efficiently heat the rooms, it is necessary to make the whole system centralized, to reduce the number of air ducts. For them it is better to use pipes made of aluminum, steel. In this case, additional ventilation is not required.

The natural gravity will help to lower hot air down in a one-story house. In a two-story building should install multiple fans. When mounting the structure, it is necessary to pay special attention to the tightness of all parts. To exclude cold air leaks from the walls, windows.

Interesting solutions in the interior

The fireplace is not only a means of heating, but also an original solution for the interior.

  • For the fireplace, you can select a separate wall, lay it out with a stone and build in the hearth. This design will become the center of the living room. Tall windows will add light and space. Above the fireplace you can hang a picture, a family portrait or a TV.
  • The corner fireplace will gather a warm friendly company from its fire. On the contrary, you can put a chair or sofa. A small coffee table fits in perfectly. To create a more romantic atmosphere in front of the hearth, you can lay a soft carpet.
