We design and create an air heating fireplace: step -by -step instructions

Do you want to improve the atmosphere and coziness of your house? Think about the efficiency and charm of an air-heated fireplace. Air heating fireplaces are a desirable alternative for people looking for both comfort and style, in contrast to traditional fireplaces, which mainly offer visual appeal. Air heating fireplaces are made to distribute warmth throughout the room. We’ll walk you through the steps of designing and building your own air heating fireplace in this guide, and we’ll provide you with step-by-step instructions to help you realize this quaint addition.

The ability of an air heating fireplace to effectively heat a space while consuming the least amount of energy is one of its main advantages. These fireplaces can assist in lessening the need for central heating systems, which could lead to cost savings and a smaller environmental impact. They do this by collecting the heat generated by the fire and distributing it throughout the space. In addition, the radiant heat produced by the fireplace can produce a warm ambiance that is ideal for unwinding on chilly evenings with loved ones.

It’s crucial to think through the layout and design of your air heating fireplace before starting construction. The size, arrangement, and state of the infrastructure in the room will all affect your choices. The fireplace should be placed in the center of the room where heat distribution will be most efficient for best results. Furthermore, you should make sure there is sufficient ventilation to facilitate combustion and avoid the accumulation of smoke and gases.

After deciding on a good spot, it’s time to assemble the project’s supplies and equipment. You might require components like metal ductwork, heat exchangers, firebricks, and mortar, depending on how your fireplace is designed. Selecting premium materials is crucial to maintaining the longevity and safety of your fireplace while withstanding the intense heat produced by the fire. Making wise decisions can be aided by professional advice and investments in trustworthy brands.

Principle of operation

The air duct system throughout the house and the casing of the air heating fireplace are its key components.

In addition to storing heat, the fireplace’s heat cover lets you direct that heat in the proper direction. This small detail occasionally raises and enhances the efficiency of heating the space with a fireplace.

The simplest laws of physics govern how the convection method of heating the space operates. The room heats up as warm air rises from the lower pipes.

Air fireplace

The air is heated by a unique liner that is housed in the firebox. The liner is encircled by pipes that are linked to pipe divorce simultaneously. The warm air heats the room as it swiftly circulates around it as a result of the fans running.

The fireplace’s air heating system

Additionally, air movement can happen as a result of the force of gravity’s attraction rather than forced ventilation. Air circulation in the space is facilitated by the temperature differential between the hot and cold gases.

However, there shouldn’t be as many pipes in this situation because otherwise the gravitational system won’t be able to provide natural air circulation.

Circulation of warm air within the home

Consequently, there are two ways to accomplish the convection fireplace’s work:

• The ascending stream from the fireplace of the fireplace raises warm air up the room.
• A descending stream, on the contrary, directs colder air to the furnace.

The owner will need to create a more intricate duct circuit where hot air will be supplied to the premises via the fans if they are trying to heat a large house with a single standard fireplace.

The home’s air conditioning system

Even a two-story house can be heated with just one fireplace and an air casing if the system is properly set up and all the laws of physics are applied.

Advantages of air heating fireplaces

What is the benefit of using convection heat transfer as opposed to the conventional fireplace device? Let’s examine this matter in greater depth:

• A conventional fireplace, without any additional devices, works according to the standard scheme: heat in it is maintained exactly to the stage while firewood is burning.

Cut

Fireplace heated by both water and air

The air fireplace casing contributes to the home’s temperature rise in a number of ways.

1. Radiation – direct air heating from an open firebox in the fireplace.
2. Heat transfer – heating the walls of the fireplace and direct transmission of hot air to the room.
3. Convection – the process of mixing cold and hot air flows in the house.

Fireplace heated by both water and air

The planning of an air heating fireplace during the home-building stage is the only consideration that needs to be made when setting one up. This has a direct bearing on the house’s wall thickness and construction characteristics.

Fireplace with air heating

Operates a closed firebox air fireplace. Numerous producers provide ready-made, monoblock sets that come with a casing right away. There are openings inside that allow for several air passageways.

An air fireplace costs a lot less than a comparable unit that has a water circuit. Furthermore, it transfers heat and is equally efficient—that is, assuming, of course, that ventilation wiring is done correctly.

An example of how the fireplace and heating system are connected

Double heat transfer occurs in fireplaces with a water circuit: the air is heated by the radiator after the water is heated by the firebox. Convection flows cause instantaneous heat transfer as well.

You can increase the heating radius from three meters to ten meters by using forced organized convection. Convection can also be used to alter the humidity level within the house, changing its climate.

This approach will, of course, cost more money, but it will guarantee the highest possible standard of comfort in the country home.

The home’s microclimate

Air heating fireplace design

The components of an air fireplace typically include the following:

1. Fireplace fireplace.
2. Portal.
3. Air pipes that increase the thermal efficiency of the unit.
4. A fireplace casing that distributes heat.
5. Fan.
6. Filter.
7. Ventilation grates.
8. Top stand.
9. Distributor and air tees.

Such heating has the benefit of being attainable in places far from the comforts of civilization. where there is no access to electricity. Additionally, a single fireplace can heat multiple rooms in a sizable house.

Hearth

The standard configuration of the air fireplace will require the addition of a special pump to facilitate the forced circulation of warm air due to the presence of two floors.

Heat exchange through the air occurs within the closed cycle.

We’ll walk you through every step with detailed instructions in our guide to designing and building an air heating fireplace. You’ll discover how to build a fireplace that not only makes your house feel cozier and warmer, but also effectively heats the surrounding air by following this guide. Everything you need to know will be covered, from choosing the appropriate materials to comprehending the fundamentals of airflow. Our comprehensive guidelines will assist you in creating a fashionable and useful air heating fireplace for your home, regardless of your level of experience with do-it-yourself projects or if this is your first time trying to improve your home.

Features of designing a fireplace fireplace

The installation of fans is a requirement for convection heat transfer, so tell us about the configuration, power, and size of the fireplace you plan to use. The only reason air circulates in a home with a fireplace and standard heating is because of temperature differences (air density).

The case’s air movement algorithm

Naturally, such convection has very little effectiveness. The direction of air flows will determine the intensity of the fireplace when artificial convection is created.

Installing fans is a crucial component. The primary characteristic of this design is its placement, which allows cold air to be supplied from below rather than from the interior. If not, the opposite procedure can be achieved.

Remember that the room has a noise threshold. A fireplace should only be placed as minimally as possible because, even with the heat that the heater produces, the space will be very uncomfortable.

I want to caution you right away that setting up an air heating fireplace in the nation is not an easy task. It is preferable to order a fan and pipes location with a fan and pipes from a specialist if you have no prior experience with this.

The idea behind this design is as follows: using fans, cold air is drawn up from below and directed into the firebox, where it is heated to the proper temperature. Subsequently, it permeates the fragments and enters the chimney’s facing casing via designated channels.

Airflow within the container

Additionally, the metal chimney releases heat, enhancing the fireplace’s efficiency. Here, hot air is circulated to its maximum capacity and is sent throughout the room by the fan.

Video. How to properly conduct an air heating calculation

This heating system’s design, which maximizes heat accumulation and retention, is appropriate for a closed firebox. With an analogous heating system, you can reach 80–85% maximum efficiency.

You must reduce the number of bends in the network of pipes, channels, and other design elements in order to maximize design efficiency. Natural circulation might be sufficient if the pipe is no longer than three meters and does not have many bends. Without more fans, you are unable to function with other parameters.

Aluminum or steel make the best air channels.

Crucial! The house’s layout is a crucial factor to consider when designing the air fireplace heating system. In the event that the house has two floors, multiple fans will probably be required. One fan will be sufficient for a one-story home with a horizontal pipe lifting.

The fireplace’s air heating system

Basic rules for installing air heating fireplaces

The utility room is the ideal place to install the fireplace fan. First of all, this won’t detract from the interior’s aesthetics, and it will also lower the noise threshold that the functional device creates.

Crucial! Such a fireplace requires a very detailed approach to operate. The fan runs continuously, which causes soot to build up on the filter and require frequent cleaning. If not, there may be a considerable decrease in the efficiency of such a fireplace’s operation.

When operating a fireplace, select a pipe diameter with a rounded section to minimize noise. There needs to be a ventilation hole with a grate in every room for such a heating system to function properly. It will therefore require a great deal of work and time to equip an air fireplace in the house if the design is not done at the time of building.

Warming the room from all angles is facilitated by closed diffusers or thermostats. The diffuser’s shape—which can be square or round—has no bearing on how well the system works.

The entire house can be heated with an air fireplace, with the exception of the kitchen, bathroom, and toilet rooms, which have separate ventilation. Lowering this factor could cause disruptions to the home’s warm air circulation system.

The fireplace’s convection chamber is composed of drywall, while the frame is constructed from galvanized profile.

In order to keep heat from escaping through the ceiling, a cut must be made.

Under the ceiling, thermothec

This helps prevent fire by ensuring consistent pressure, system ventilation, and optimal fire safety. For this reason, when using an air fireplace for heating, certain security precautions should be taken both during unit construction and during operation.

Let’s focus on the arrangement’s main points:

1. The fireplace furnace should stand on a strong stand made of brick.
2. The foundation for the fireplace should be separated from the main foundation of the house.
3. The system should be closed with drywall sheets.
4. Air ducts must be divorced throughout the house.
5. The duct of the ducts must be placed in the technical room.

Let’s examine the primary benefits of an air fireplace casing:

• An increase in efficiency. When compared with a conventional fireplace, which gives an efficiency of 30-40 %, then air heating increases performance to 80-85 % depending on the system of arrangement of channels and pipes.
• Fuel consumption is reduced by 20 %. Even after the complete attenuation of solid fuel, warm air continues to move around the room.

The benefits of this type of heating system, when enumerated, speak volumes about why this project must be carried out.

Correctly select an air heating fireplace

After deciding to install air conditioning in the home, it’s critical to select the appropriate fireplace in addition to creating a skillful project plan.

In this instance, the home’s standard system selection method will not function. While it is customary to select the firebox’s power according to the room’s size, there are other guidelines that apply in this situation.

The truth is that an excessively powerful furnace will cause the room to become overheated, making the occupants uncomfortable. We’ll need to keep an eye on the quantity of firewood and ventilate the space, which will be more work and may cause colds, among other things.

Table of computations for fireplace power

In addition to the room’s area, the number of rooms and floors in the house, the number of windows, and the kind of ventilation system must all be considered for an accurate calculation of the fireplace power.

DIY air heating fireplace installation

Step 1. Preparatory work

1. Bulletproofing material and tool.

The following supplies must be ready before moving forward with the air heating fireplace arrangement.

Supplies required for installing the furnace.

• Red, full-bodied ceramic brick (M-150.)
• Shamotnaya (refractory) brick.
• Pantry (sand, red furnace clay).
• Material for the foundation (cement, gravel, sand).
• Ruberoid.
• Ceramic tiles for the base and wall cladding.
• Boards for creating formwork.
• Reinforcing mesh.
• Foil for thermal insulation of the casing.
• Cast iron firebox with glass.
• Thick -walled pipes.
• Ventilation nozzles – 4 pieces.
• Flexible pipes (metering depends on the area of the room).
• Fans (the number depends on the number of rooms in which they will be installed).
• Metal corners.
• Pipes like sandwich.
• Clinker tiles for cladding the portal of the fireplace and air cover.

Equipment required to install a fireplace.

• Building level.
• Sutual shovel.
• Construction marker.
• Drill and Bulgarian.
• A hammer and a chisel.
• Measuring tape (roulette).
• Building plumb.
• Augoter.

1. Determine with the place of fire arrangement and perform the drawing.

This is one of the main components of the heating system, affecting comfort levels within the home, operating simplicity, and heating efficacy. Naturally, this factor is heavily influenced by the owners’ individual preferences.

The primary decorative element of the room, the fireplace, is something that many people desire to see in the center. But you also need to consider where the doors and windows are located. Remember that every doorway produces a curtain of cold air that prevents the warm air from the heating device from normally circulating.

Determining that the device is not in a straight line with the door makes sense in this context.

There are multiple ways to install the device.

Halled. This type of installation is one of the most popular. The very name of this method suggests that part of the fireplace structure leans against the wall. In this case, usually the chimney is masked under the wall or is part of it.

A fireplace in the wall

Such installation necessitates a more comprehensive handling of the fire safety problem. When placing basalt fiber where the device comes into contact with the wall, it is important to consider the fireplace’s thermal insulation.

The fireplace arrangement allows for the unit to be positioned either frontally or angularly. It is entirely up to the customer and has no bearing on functionality.

Large living rooms are best suited for heating with the front option. Experts advise choosing corner fireplaces for tiny rooms. As a result, the gadget will heat the surrounding rooms as well as the room itself using the standard method of heat transfer.

1. Built -in fireplace.

This is the best choice for a tiny space. It fits into a unique niche and requires very little room, but since you have to exit the chimney, this option needs to be included when building a house.

1. A separate fireplace.

An independent fireplace

This choice would make a stunning and fashionable addition to any house. However, in this instance, all that needs to be done at the house-building stage is to perform the chimney only through the roof.

Step 2. Fill the foundation for a fireplace

This is a crucial step that will determine the strength, dependability, and future efficacy of the design. Naturally, it would be ideal to construct it before the house. Next, the space under the stove will be designated, and at the erection stage, the foundation will be posted.

In no circumstance should the foundation for an air-heating fireplace be connected to the home’s main foundation. The furnace base shouldn’t be distorted when shrinking a house or other phenomena.

Fill in the fireplace’s foundation.

• We measure the size of the foundation. He must go beyond the perimeter of the fireplace by 15-20 cm.
• We tear out a pit 70 cm to build a strong base for the fireplace. Use a bayonet shovel for this. Focus on the soil layer that will freeze in winter.

The fireplace’s foundation-laying plan

Step 3. The laying of the base of the fireplace and the thermal insulation of the wall

It is essential to measure the floor’s slope using the construction level before moving on to lay the base. He needs to be flawless. Therefore, there is no way to fix this step.

• Laying of floor tiles. She should go beyond the perimeter of the fireplace by 15-20 cm. In order to ensure the perfect adhesion of tiles on the floor, use special soil to lay the tile. Mix it thoroughly and apply to the floor surface in one layer. Leave the solution for 24 hours until it dries completely.
• On dried soil, apply tiles with an uniform layer.
• Start laying the tile from one of the corners. If you first lay out the tile, then make small seams 2-3 mm. This will visually hide the errors. To do this, use building crossings for laying tiles.

We arrange the ceramic tile foundation.

Wooden tile arrangements

Step 4. We perform the walls of the fireplace walls with thermo -insulating material

In a country home, fire safety must be considered when installing a fireplace. particularly if a corner fireplace is placed close to wooden walls.

• For thermal insulation, you can use the basalt fiber or the stoves of the superizol. Also, facing material can serve as the same tile with which you performed the base.
• To stick tiles, choose a heat -resistant mixture. Do not forget to check with plumbing the evenness of the laying of tiles or decorative tiles.

Step 5. The construction of the pedestal, brick apron and installation of the furnace

The heart of any fireplace is topka. You can use Chamotis bricks for its arrangement, or you can purchase a pre-made metal structure.

Pedestal made of bricks

It takes a lot of time, strength, and knowledge to properly mason a brick firebox. As a result, we will focus on installing a completed cast-iron furnace.

• Topies are being built for a prepared brick base. Air mass convection works in such a way that warm air from under the wood will go out, mixing with cold.
• We build a base of aerated concrete blocks or brick. Ass concrete blocks of the material have sufficient strength, but it is much easier than brick. After all the work is completed, the base will need to be decorated with facing artificial stone or plaster.
• We put aerated concrete blocks on construction glue.
• Install metal corners that will give the reliability of the structure.
• Using a file, we make grooves in bricks (blocks), which will include a cast -iron firebox.

Install the pedestal furnace.

Iron furnace made of cast iron

Step 6. Installation of the chimney system

To properly operate a system for extracting combustion products, start at the fireplace chimney opening. It is the eighth in the combustion opening’s total area.

We install a sandwich-style chimney consisting of two pipes that are removed either through the wall or the roof. The procedure is dependent on how the house is built.

Attachment of the chimney to the furnace chamber

• Connecting the chimney starts from the device, and not vice versa.
• Through the gate, connect the outlet hole of the furnace chamber to the first element of the chimney pipe. The joints are well sealing and tighten with a clamp.
• Observe the smooth line of the chimney and try to do as little branches as possible. If the layout of the house and the connection diagram requires that, use the branch. Avoid making a chimney, otherwise it can adversely affect traction.
• When the design of the chimney reaches the wall through which you need to perform a hole or roof, use a metal passage pipe with mineral insulation.
• Gradually increase the entire chimney and remove it above the roof, reliably fixing with clamps.
• Cover the upper part with a cap and a grille that prevents the ingress of precipitation and garbage into the chimney.

Step 7. Performing an air cover

We start building the air casing after the firebox is attached to the chimney. This stage is related to both decorative and functional tasks.

An additional heat source will come from a sort of air pocket that forms inside the cardboard structure.

We construct a drywall frame.

• We build a frame from a metal profile around the fireplace.
• We measure drywall according to the drawing and cut out using a grinder or saw. The shape of the casing can be any – it all depends on your personal preferences.

Cardboard case made of hypsum

The fireplace’s exterior

We create gaps.

Making the holes square is preferable if you do not intend to separate from the house of air pipes in the near future. It is preferable to drill circular holes for pipe connections if you wish to install an air duct system and improve the efficiency of heat transfer. Put the pipes in place.

Putting in thermal insulation within the shell

The perspective from within the container

We manufacture flexible pipe wiring for air ducts.

Carrying out a horizontal channel

Install the fan in each room to provide forced traction. Since hot air tends to rise, it is preferable to extend flexible pipes beneath the ceiling.

Installing air piping beneath the rafters

Assembling air ducts

Step 8. Fireplace cladding and finishing work

Facing, the last step, serves more purposes than just aesthetics. Tiles make it easier to maintain the fireplace, eliminate the need to constantly color the plaster, etc. Furthermore, well-built cladding will strengthen the entire structure and prevent it from cracking by acting as a protective layer.

Using tiles as a facet

Depending on your interior design and personal preferences, you can use red brick, ceramic tiles, or facing decorative stone as an outer layer.

It is best to use adhesive mixtures specifically made for high temperatures when laying decorative tiles. The clay mixture pantry is also an excellent option if money is tight.

Keep in mind that adding more material to the stove’s exterior will cause the return heat to decrease. Applying a thin layer of decorative plaster to drywall would be a great solution.

• Make marking clearly in size of your tile. Consider the gap. First, count “for dry” how many whole tiles you need. Sprinking on ½ and ¼ part of the tile is better after the row is laid out “on wet”.
• If the design of the fireplace provides for the skirting board, then retreat in its height a row and begin to lay out the tile.
• Gently, starting from the corner, begin to lay the tile, applying the solution with a thin layer on the tile. Remove the remaining solution immediately.

Clinker tile installation

The gun-sealed seam filling procedure

Since the fireplace’s primary purpose is decorative, both the lining and the casing itself can be made in any style.

We suggest taking into account the initial concepts for air casing decoration:

Step 9. Kamina printing and traction check in all rooms

The fireplace must be lit for the first time after all finishing work is finished and the air supply system is fully installed. It is advisable to allow all adhesive and cement solutions to thoroughly dry for a few days.

• Take away easily flammable objects away from the fireplace and lay a small number of firewood. Use only well -dried firewood.
• Close the furnace door tightly before the flame flares up.
• Do not give a strong heat of the furnace right away, warm up gradually.
• Check traction in each room, whether fans work correctly.

You will have an extremely efficient heating system if everything is done correctly. One fireplace can heat an entire large house because of air channels and forced circulation of warm air.
