Heating of a private house with your own hands with hot air

A private home must be heated in order to provide a comfortable living space, particularly in the winter. Although there are many different ways to heat a space, using hot air can be a practical and economical solution. It is totally feasible to install a hot air heating system in your home yourself if you have the necessary skills and equipment.

Via ducts and vents, heated air is dispersed throughout the house to provide hot air heating. A furnace, also known as a heater, generates heated air through the use of fuels such as electricity, gas, or oil. This technique allows you to quickly reach a comfortable temperature throughout your house and is very controllable.

When thinking about installing hot air heating in your home, adequate insulation is essential to guaranteeing effectiveness. Retaining heat through effective insulation lowers energy waste and your heating costs. You can save money on energy bills and create a comfortable and cozy home environment by combining efficient insulation with hot air heating.

Fields of use

There is a growing trend in the use of heating design and installation for heating residential spaces. They are efficiently heated by large hangars, contemporary supermarkets, shopping malls, and warehouses. Forced circulation is more frequently utilized in these types of spaces, allowing for automated temperature control and uniform heat distribution.

Equipment

Redirecting air heating for the purpose of heating the premises is the foundation of the air heating system’s operation. The following hardware is included in the system for this purpose:

• gas air heater (or other model depending on the fuel) is the main heat source;
• heat exchanger – warms the passing air, and does not allow mixing flows with outgoing gases;
• air ducts – redirect the flows of warm air to the interior;
• filter, humidifier and freshener – maintain the quality of the air, cleansing it of dust and bacteria;
• central air conditioner – used to maintain comfort inside the building through the existing air duct system in the summer;
• Automation system – monitors the temperature regime of the room, controls the temperature, the operating mode of the heat generator.

Principle of operation

A private home’s air conditioning system operates on specific principles. Take a closer look at the algorithm:

Air heating to the required temperature

A heat generator using electricity, steam, hot water, or any fuel does this. Automation regulates the device’s operation; once the target temperature is reached, it switches off and operates in duty mode.

Air redirection inside the premises

The round and rectangular air ducts explain why this occurs. Rectangular shapes fit better inside a private home due to their more precise design, while rounds have less aerodynamic resistance.

Warming up the room

The air flow enters the room at the exit through a special distributor, evenly warming it. Via the pipes of an independent air duct system, the cooled air is then returned to the heat generator for further heating. Flows circulate, and how well they do so depends on the equipment chosen, precise engineering calculations made, the fuel chosen, and the temperature regime.

The air heating system circulates either naturally or artificially. Warm air rises to the top and naturally makes way for the room that cooled after heating. The fan facilitates forced circulation by creating pressure that forces air to flow through the air ducts.

Advantages

There are several beneficial advantages to the air heating system. Think about the principal ones:

High efficiency

Such a device has a high efficiency and heats up a large area of the building as quickly and efficiently as possible. All of the rooms have equal distribution of heated air, making it easier to keep the entire house at a particular temperature.

Additional functions

For instance, a country home’s air heating system works well in the summer because it allows for ventilation and air conditioning when the air conditioner is connected.

When additional filters, humidifiers, air fresheners, and heating are used, the heating system carries out its general duties and maintains home comfort. Thus, the house establishes a center of comprehensive air processing that does more than just heat the air—it also cleans and processes it.

Economy

Completing the calculation of the heated area and air heating at a cost of one cubic meter is simple. The operational expenses that follow are negligible. Fuel savings are markedly increased when rooms are kept at a normal temperature without being overheated, above 24 °C. In this instance, the energy consumption is 1.5 times less than that of water heating.

Independent installation

You can conduct air heating yourself and save a great deal of money. This should ideally be done during the building phase. The following steps are involved in installing the air heating system:

Conducting calculations

This is one of the hardest and longest phases, requiring careful work, knowledge, and abilities. You must consider a number of crucial factors:

• calculate heat loss separately for each room;
• select the type of air heater and its power depending on the indicators of heat loss;
• Based on indicators of the heater power, calculate the amount of warm air;
• make an aerodynamic calculation of the entire system;
• calculate the required diameter of air channels.

Buying equipment

The most crucial component, the heat generator, should be purchased first. Fuel consumption indicators and heated area size should be taken into consideration when making this decision.

The best place to buy air ducts, tips, and throttle shutters is from a specialized company that manufactures ventilation equipment.

The remainder, however, which includes insulation, mounting tape, screws, aluminum adhesive tape, etc., can be found at any stoop market.

Features of installation

The main air duct is mounted initially when this heating system is installed. Typically, it is constructed of galvanized steel and then adhered with 3-5 mm thick foil insulation.

Subsequently, the smaller air duct system that branches off of the main is installed. A throttle must be installed in each supplying duct for the system to be easily regulated.

It is preferable to leave a 50 cm long space at the end of the trunk air duct where thin air ducts should not be inserted. As a result, the device’s whole length will experience constant pressure, and the side branches will receive the same volume of air.

All of this comes after the air heater is installed. It has all the landing holes needed for fastener systems and extra equipment, such as filters, air conditioners, and air sterilizers. The complex can be assembled in no more than an hour. It will take some time to connect all of this equipment, though.

Based on all of this, we can say that air heating is a contemporary and efficient solution that is gradually making its way into Russian homes after being utilized for a long time abroad.

How do air heating with your own hands is made

The house’s air conditioning system

A comparable heating technique has long been recognized. Hot air from melting furnaces traveled through channels designed specifically for this purpose to heat homes even in the prehistoric past. And because air heating has so many benefits over other heating methods, many people these days are considering how to create air heating in a private home on their own.

What types of air heating exist

Knowing the different types of air heating systems is necessary to select the best one for a private home. Several criteria can be used to categorize similar systems:

• Method of circulation of air masses.
• Place of location.
• Scale.
• The method of heat exchange.

The method of circulation

Fans or natural air movement are two ways that air circulation can occur. In a natural way, the air masses rise up because they are lighter, and they enter the room that needs heating through air ducts that are, in this case, under the ceiling. The premises are heating slowly and the air speed is low at the same time.

Forced circulation proves to be more profitable because it moves through the channels much more quickly when hot air powers the fans and does not have time to cool down. Because less cool air is needed for heating, fuel is saved.

Location

The air heating location in a private residence is shown as:

• floor system;
• Suspended scheme.

In the first design, the ducts are under the ceiling in the upper portion of the space and can be concealed from view by using ornamental accents. In the second scenario, the hot air channels are either skirting structures or under the floor.

The floor plan with the air ducts located in the preferred location is ideal for a private home because the air warms the room more evenly in the lower half, making it more comfortable for occupants.

Since warm air cannot travel from suspended structures to the floor, coolness is always felt at the level of the legs.

Scale

This parameter distinguishes between local and central air heating. A small private home is heated as part of the local scheme.

Many commercial and public buildings, including production workshops, supermarkets, stations, waiting rooms, sports complexes, hangars, and warehouses, rely on the central system for heating.

Heat exchange

For both interior and exterior air heating within the building. This type of system is referred to as a supply if the air is only drawn from the street. The supply type fans are used for this, pushing air masses straight into the heating unit.

A partially recirculated air system includes an air fence that has already cooled to the lowest possible level inside the building and from the street.

The entire recirculation scheme involves the internal air being constantly moved, first from a heated to a cold state, then to a heating device where it is heated once more before returning to the premises to provide cooling and heating.

Air heating device

Gas air heater usage

If you plan to handle everything yourself, regardless of the plan used to heat a private home’s interior, you will need to gather the following three essentials:

• Heat generator. To do this, as a rule, a heating boiler is used or, as a last resort, a stove. The boiler can work on any type of fuel or eat from the mains.
• A network of ducts, usually made of galvanized sheet steel. They have an unsightly appearance, but are often decorated with various finishing materials in accordance with the general design of the room.
• A supply fan.

When installed with your hands, this air heating design can efficiently and rapidly heat the space. Climate control devices that operate in a similar manner during the summer months will also be doing air conditioning and mass air cleaning. Depending on the chosen air heating scheme, the air conditioning units are positioned both below and above the room.

Heater air is forced into the channels by the supply fan. It is installed directly beneath the boiler’s combustion chamber, and in order to serve the heat exchanger—the heating site—it is fitted with a filter that removes dust and other impurities. The cooled air returns to the heat exchanger after traveling through the ducts.

Heating your private house with hot air can be a cost-effective and efficient way to stay warm during colder months. By harnessing the power of a simple wood-burning stove or a dedicated hot air furnace, you can distribute warmth throughout your home without relying on complex heating systems. Proper insulation is key to maximizing the effectiveness of this method, ensuring that the heat stays inside where you need it. With a bit of planning and the right tools, you can create a cozy and comfortable living environment while also saving on energy costs. Whether you"re retrofitting an existing home or planning a new build, hot air heating offers a DIY-friendly option that can suit a variety of needs and budgets.

What are the advantages and disadvantages of air heating of a private house

The benefit of air heating is that you can heat your home quickly, effectively, and economically in general. Furthermore, the benefits comprise:

• Air heating efficiency reaches 90%.
• The need to install radiators, pipes and the cost of acquiring them disappears.
• The ability to combine heating and air conditioning.
• Maximum safety due to the use of heated air as a coolant.
• Low cost of such systems.
• Low inertia of air masses allows you to quickly warm up the premises.
• Air heating can be used to heat any rooms, regardless of their area and number of storeys.

Additionally, there are drawbacks. And that’s what they are:

• The air heating system should be installed during the construction of the building.
• Requires constant observation and frequent maintenance.
• Forced circulation is energy -dependent, therefore, in case of turning off the electricity, it is necessary to have a spare power source.

Drawing up a project

Similar to any other air conditioning system, a private home’s primary project can be completed by hand. The following needs to be considered in the project and calculation:

The gas heater’s apparatus

• The heating boiler of the corresponding power, which, taking into account heat losses, is able to heat all rooms.
• The speed of the warm air masses.
• The amount of heat that the building loses through the walls, roof, floor, windows and doors.
• Aerodynamic characteristic, which depends on the section of the ducts, is calculated to determine the reduction of the pressure of the air flow.

Make sure you have sufficient knowledge before beginning the heat engineering calculation. A poorly executed project can result in phenomena like the perpetual draft in residential buildings, which is contagious and causes colds, as well as the constant sound of a running fan and vibration, which is inevitably produced in the air ducts. Furthermore, the heating unit itself may fail as a result of the heat exchanger overheating.

A ventilation device is used in a private home’s air conditioning system to remove old air from the interior and replace it with fresh air.

It is important to consider that a ventilation system supplies approximately 25% of the room’s chilled air from the outside when performing thermal engineering calculations.

Following the computations, you must decide where the air ducts will be installed. They can be found under the ceiling or made of skirting board, as was previously mentioned. Here, guidelines and directives are absent. Everyone is allowed to select what best suits them. In any case, the ducts’ sleeves ought to be positioned at both the top and bottom. Since the entire room should be filled with moving air masses. It is advised to place the warm air supply channels’ outputs where people are most likely to be found and where they stay the longest.

How the air heating system is mounted

The heating unit needs to control the fuel combustion process and have all the required security controls. Temperature sensors are also required.

As previously mentioned, designs made of flexible metal sleeves and galvanized metal can be made with your hands and used as air ducts. Using reinforced tape or specialized clamps, the duct’s flexible and rigid components are combined. The home owner requests that the air ducts be shaped a certain way.

In order to prevent condensation from appearing on the outside surfaces of the air channels, if the installation of air conditioners is scheduled, a layer of thermal insulation needs to be placed over the ducts. Any material from the heat insulator line can be used to warm air ducts. Utilizing self-adhesive materials is advised by experts.

Conclusion

As you can see, you can easily install air conditioning in your home yourself, but you should hire professionals to do the heat engineering calculations.

Air heating of a private country house: the principles of the device, the selection of equipment and the calculation

While air conditioning is a safe and common method of heating homes in developed America and Europe, water heating systems are typically designed in Russia. On the other hand, a country house’s air heating system can achieve up to 90% efficiency, while the water system can only provide up to 60%. What makes heating with air so appealing? Let’s solve it together.

How such a system works?

Air heating is incredibly useful. Content owners who use this method to heat their homes recognize the obvious benefits:

• Absolute security. Highly sensitive automation clearly controls all processes. With the slightest threat of leakage or other danger, it instantly blocks the equipment. In addition, the system does not have a pipe filled with the coolant, therefore, in principle, their tears, leakage, etc. are impossible.P. troubles.
• High heating speed. The full heating of the room takes from 20 to 40 minutes, even if the initial temperature in the house was negative.
• Economy. Low power consumption, high efficiency and the absence of intermediate coolants make air heating of a private house extremely profitable.
• Reliability and durability. Subject to competent design, installation, regular maintenance and necessary repair, the system will last at least 20 years.
• Simplicity in operation. Automatic management of launching processes, stopping and changing modes allows you to easily adjust the temperature in the house and at the same time insures from possible errors.
• Available installation cost and a fairly quick payback period of investment.
• Aesthetics. The absence of familiar batteries in the room makes it possible to install windows of almost any size, frees space and opens up opportunities for design experiments.

Conventionally, heat generators are recommended for use with air heating systems. The room is heated by the air that has been heated to 45 to 60 degrees inside the heat exchanger and travels through the air ducts. The heat generator receives the cooled air that passes through floor grilles or reverse ducts.

The heat exchanger and the air guide fan are the two primary components of the heat generator.

There are various methods by which air heating can be done:

• heat pump;
• a gas burner using both cylinder and main gas;
• hot water from a centralized boiler room;
• diesel burner.

The system’s average air flow is between 1,000 and 3,800 cubic meters per hour, with a pressure of 150 PA. Long ducts may seem to be the source of heat loss in large rooms. In these situations, it makes sense to consider setting up multiple air ductless heat generators. Experts advise that the main duct’s length not exceed thirty meters, and the branches’ length not exceed fifteen meters.

Since it seems somewhat illogical to use the system only for heating the space, the air cooling unit is typically added to the apparatus and is then used to power the external air conditioning unit. As a result, the system combines air conditioning and heating, enabling the home to be kept comfortably cool throughout the year. Additionally, you can use air purifiers and humidifiers to create a special, healthful microclimate in the rooms.

The following can be used to outfit the cottage’s air conditioning system:

• Natural ventilation. The easiest option is when the air rises due to the initial heating. He enters the rooms in the air ducts, heats them and returns to the heat exchanger. The main disadvantages of natural ventilation are clearly manifested in case of additional receipt of cool air through the doors or windows. In this case, the cold air, which is larger, accumulates in the lower part of the room, creating a skew of the temperature regime and interfering with the normal functioning of the system.
• Forced ventilation. Air circulation is provided by a fan that creates pressure in the system. The room warms up much faster due to the larger speed of air movement. It is also easier to adjust the temperature in the rooms. A small drawback of the structure can be considered a noise coming from the air ducts.

Rules for the selection of basic equipment

Air heating systems’ thermal generators can run on a variety of fuels. Selecting the best option for your house based on all factors is crucial. Natural gas or fuel that has been liquefied can be used. Fuel type conversions are possible thanks to the provisions made by manufacturers. This can be accomplished by simply replacing the burner, as with gas and diesel fuel, or by installing a new nozzle with a different passage hole diameter when converting from liquefied gas to natural gas.

Many different parts make up an integral system, and each part must be carefully chosen to function with the others (click the image to enlarge).

A fuel tank, pipeline, and additional filter installation are necessary for a liquid fuel system. Additionally, additional equipment will be needed to work on liquefied gas during installation. Should cylinders be used, a room dedicated to their storage must be equipped. An alternative is to think about the so-called gas holder, which is a device that looks like a gas tank that is buried. The only systems that won’t need extra equipment are natural gas ones.

Additionally, the ducts may differ:

• Round. Have a slight aerodynamic resistance, which slightly increases the overall efficiency of the system. Fastened with each other with clamps and stilettos. The inner diameter of the pipes varies from 100 to 200 mm.
• Rectangular. Most often they are installed in air ducts with a large section. They fit more harmoniously into the interior, so they are preferred when arranging the heating systems of residential buildings.

Anchors hold both kinds of structures to the ceiling. To prevent heat loss, ducts that must pass through unheated areas must be insulated. A unique metal cover that is larger than the air duct is installed during the installation of structures between the ceilings. Thermal insulation of the system is a must. Within the air duct’s ducts are installed air distributors and air intake devices.

Installing air distributors and intakes at the room’s air duct output locations is a must.

An economical and effective way to keep your house warm during the winter is to heat it with hot air. You can create a cozy living space without going over budget by making the most of a basic heating system.

The ease of use of hot air heating systems is one of their main benefits. Even people with little DIY experience can install a hot air heating system with simple tools and supplies. For homeowners wishing to do their own home improvement projects, this makes it a popular option.

Furthermore, hot air heating systems have rapid heating capabilities, so you can almost immediately feel warm. This quick reaction is especially helpful when there are unexpected drops in temperature, making sure that your house stays warm when you need it most.

In conclusion, using hot air to heat your private residence offers a practical and effective way to keep your home cozy and welcoming. For homeowners looking for economical and comfortable heating options, a hot air system is a sensible option due to its easy installation process and rapid heating capabilities.
