How is air heating of a private house produced? Do-it-yourself air heating of a private house: nuances of organization and installation Hot air heating

The working scheme of air heating includes a minimum set of equipment:

1. heat source (heat generator);
2. air ducts delivering heat to heated areas.

Examples of homemade air heating are presented in detail on the Internet with photos and diagrams, but interest in such systems does not wane. The advantages of air heating include:

• high efficiency, reaching 93%;
• direct heat transfer to heated areas without pipes, heating radiators, etc.;
• the ability to create a room microclimate by combining heating with a climate system;
• power and low inertia of air heating, allowing you to quickly warm up your home to the required temperatures.

We will present several ways to install air heating in a private house on our own, and note the pros and cons of each method.

How to make air heating of a private house from the sun

The advantages of solar heating are obvious - the homeowner only invests in the purchase of equipment, and the heat source itself costs nothing. Solar power plants pay for themselves in about three years, and their service life is ten times longer (up to 30 years).

There are two types of solar heating: solar and .

Advantages of solar heating:

• absolute environmental safety;
• ease of operation;
• constant development of production technology and reduction in equipment costs.

Among the shortcomings we note:

• low station productivity on cloudy days;
• the still high cost of equipment and installation;
• the need for accurate calculation and correct placement of equipment for maximum productivity.

Solar powered installations

The operating principle of such installations is based on the formation of direct current by sunlight when it hits special semiconductors. The converter converts direct current into alternating current. The voltage that appears in the solar panels is transmitted to the heating system. The energy can also be stored by the battery and then used in cloudy weather.

Solar batteries are technically difficult; their production will require knowledge and skills. In addition, such equipment is usually used to. This type of heating is used where there is electric heating - or. If the installation power is sufficient, then you can provide the house with hot water.

The efficiency of batteries depends mainly on the amount of solar energy. In middle and northern latitudes, where there is not enough sun, it is recommended to use combined installations in which solar panels will play a supporting role.

Installations on solar collectors

The principle of operation of such installations is also based on the collection and conversion of solar energy, only the transformation occurs not into electrical, but into thermal energy. The coolant in the collector heats up under the influence of sunlight and releases its heat into the room. The performance of such an installation also depends on the amount of sunlight.

Heating installations are classified according to the type of coolant:

• water and antifreeze;
• air.

The procedure for installing a solar collector:

1. Insulate the wall of the southern side of the house with polystyrene foam and paint it with black paint.
2. Sew wooden slats on top.
3. Punch 2 convection holes for cold air from below through the wall of the house and the insulation from the edges, and 1 from above for hot air. The diameter of the holes is 20 cm.
4. Sew corrugated sheeting onto the slats and cover the top with black plastic film (preferably glass).

The principle of operation of the collector is very simple: cold air circulates from the house through the lower openings, heated air enters the house through the upper convection opening.

In November, at noon at a temperature of 9 degrees on a sunny day, the air supplied to the house is heated by the collector to 46 degrees.

How to make air heating with your own hands from a stove

When calculating air heating, it is assumed that 1 kW of heating device power can heat 10 sq.m of a well-insulated room. Fireplace inserts with a power of 10 kW are respectively capable of heating a house with an area of ​​100 sq.m.

Natural convection systems

An air heating system from a stove (fireplace) involves the distribution of heat to other rooms of the house by streams of heated air. For this purpose, flexible heat-insulating channels coming from the fireplace are usually used.

The movement of heated air flows can be natural or forced. If the air flow is directed vertically, then natural movement will be ensured; if hot air needs to be supplied over long distances horizontally, then forced supply is needed. A project for air heating a house from a fireplace should make maximum use of natural convection, which requires large-section air ducts.

Fireproof materials and minimal aerodynamic resistance are the main requirements for air ducts. The length of the air duct from the fireplace to the room should be no more than 3 m. There should be no narrowings or bends on it. The natural air movement heating system can heat no more than 4 rooms. During installation, special attention is paid to insulating sections of air ducts near flammable building materials.

Forced convection systems

The principle is to collect air in a convection chamber and pump it from there into different rooms of the house with one or more duct-type fans. The heat supply distance is no more than 10 m. Flexible ventilation ducts or air ducts of small diameters are used.

How to make air heating based on buleryan

The Buleryan stove was developed for Canadian lumberjacks. Due to its unique characteristics, it spread very quickly, and today buleryan is used for heating homes, factories, garages, greenhouses and other facilities.

The operation of the furnace is based on the principle of gas generation, i.e. “smoldering” combustion mode with oxygen deficiency. Cold air enters the furnace openings from below, and air heated to 60 - 80 degrees comes out of the pipes of the upper part of the furnace. The combustion mode in such a furnace is full, i.e. with afterburning of combustible gases in a furnace with air supply. The stove is very economical - one load of firewood is enough for 6 - 8 hours.

Do-it-yourself air heating of a private house from Buleryan is achieved by connecting air ducts to the stove pipes and distributing heat through air ducts throughout the house. Ducts can be made of corrugated aluminum or tin. Air ducts transport hot air only from the furnace; there is no return flow, which reduces heating efficiency.

How to make air heating from cans

Do-it-yourself air heating of a private house from cans is an example of self-manufacturing of an effective heating system from scrap materials.

1. Making air flows

1. You will need 196 soda cans, which need to be washed and holes made at the bottom and top.
2. Fasten the cans together with silicone, making a pipe of 14 cans. There are 14 columns of 14 cans in total. These are the channels through which warm air will enter the house.

2. Making a box for the collector

• For the box you will need plywood and boards, PVA glue, high-temperature silicone, and mineral wool for insulation.
• The board needs to be cut to size, the joints must be nailed and glued.
• The finished dry box must be insulated with mineral wool.
• In the top wall you need to make 14 holes to fit the size of the can. These are places where warm air collects.

3. Manifold assembly

It is better to see the assembly of the collector and its preparation for operation - the whole process is shown in detail in the video at the end.

The collector is capable of heating the air to 70 - 80° C. The use of such a collector can significantly save the consumption of natural gas and electricity for heating.

This is what a collector made of aluminum cans looks like

conclusions

The variety of air heating systems allows you to choose a convenient and most efficient scheme for each specific case. The popularity of air heating in the USA and the EU is not accidental - the efficiency of such heating installations is about 90%, while that of water heating, which is popular in Russia, is no more than 60%. The future lies in inexpensive and efficient air heating methods, so now you need to select installations and use them to heat your homes.

Heating a room with warm air is very popular. It is safe to use in industrial and warehouse premises. For the heating system, 2 types of equipment are used - duct, local. Using electricity, gas or other alternative fuel, the air in the building is heated and a comfortable microclimate is created.

Air heating system

The heat generator warms up the air in the cottage. Ventilation of the house plays a primary role for the normal circulation of warm flows. She doesn't let them stagnate. An unusual coolant - heated streams - completely heats the room. The air heating system consists of the following elements:

• boiler, oven, curtain;
• fan;
• heat exchanger;
• air filter;
• pipes of the appropriate diameter.

Often water is used as an intermediate coolant in a heating system. The thermal energy generator will be a heat pump or boiler room. You can do without an intermediate coolant: heat will come from fuel combustion or from electricity. Heaters are divided into direct or indirect heating equipment.

Gas

This type of heating is the most common. Initially, it is worth drawing up a calculation plan with a specialist. This will allow you to achieve high efficiency of the gas device. Air heating using gas heats the air evenly and efficiently. Gas or diesel furnaces are used to install the system. They have a fan that circulates hot air. The disadvantage of gasified heating is the dryness of the microclimate. The solution may be to purchase humidifiers.

Air heating with wood

Before buying a solid fuel boiler, you should seek advice from specialists. They will tell you which model is suitable for heating the required cubic capacity. Air heating with wood requires additional costs for the regular purchase of fuel. An important point is the construction of an air vent. The combustion chamber is fueled by firewood, which lasts for about half a day.

The operation of the boiler can be adjusted by setting the desired temperature, which is economical. If the combustion chamber is large, then fuel will have to be loaded several times a day. The advantage is that this coolant has zero emissions. To avoid heat loss, it is important to protect the house from drafts; the best option for air circulation may be to install forced ventilation. Different models of solid fuel boilers operate on fuel in the form of:

• pellets;
• hardwood;
• shavings.

Air solar heating

Leading Canadian companies have released dark facades with micro-holes for air circulation. Their installation requires a gap of 20 cm between the wall and the facade. The hot flow will be captured through a fan at the top of the wall. Air can enter the building through the ventilation system. Solar air heating is a practical heating method. It prevents overheating and excessive dryness inside country houses and industrial buildings.

Fuel in the form of solar energy is stored in the façade of the building. The advantage of such a heating system is the savings in heating costs. There is no need to spend money on a complex system or a heating vent. This heating method is environmentally friendly, and therefore has gained popularity in many countries around the world. Although there is a minus - the high price of solar facades.

Electrical

A comfortable indoor microclimate is also created by electrical equipment. You can create electric air heating for a private home using electric curtains. Heating the room with air using such devices can be combined with a fireplace. This type of equipment has a simple design and is easy to install. Another plus is the ease of control. Electric models are mounted at doorways and windows. Heating with hot air dilutes cold wind currents in the lower tier.

The price of such a technical solution starts from 3,000 rubles. The curtain is attached to the wall in a horizontal position. The advantage of this heating system is that you do not need to spend money on purchasing and installing pipes and radiators. Electric curtains are also used for heating industrial buildings. Devices are divided into: interior, household and industrial. The advantage is that air heating occurs quickly and efficiently.

Air heating circuit

It is important to highlight the main points of the operation of such a system. The influent wind masses heated by the stove or boiler enter the main line from the pipelines. Then, through branched flexible ventilation ducts, the flow warms up adjacent rooms. To cool the wind masses in the summer, it is worth installing an air conditioning system. The air heating scheme requires mandatory approval and installation of the chimney.

With your own hands

Before proceeding with installation, it is necessary to draw up a diagram that includes the following elements:

• air heater (furnace, gas boiler, air curtains);
• main rigid air duct;
• adjacent flexible air ducts for distribution with adjustable dampers;
• feed grids at the end of the pipes;
• insulation 25 mm thick;
• Silencers are built into the air ducts.

The main pipe line is installed under the ceiling, and on the second floor the installation is carried out in the walls. Grilles supplying hot air are installed above windows, doors or passages, but not in places where a bed or sofa is located. It is easy to install air heating of a private house with your own hands, the main thing is that the construction of the walls of the future house is carried out taking into account the laying of air ducts.

Air heating calculation

The joint work of engineers at the design stage will help create an efficient and aesthetically pleasing heating system for a country house. To do this, you need to make the correct calculation of air heating, the principle of which is as follows:

1. Calculation and identification of heat loss in the house.
2. Selection of a boiler or other heating device with appropriate power.
3. Based on the selected equipment, the volume of heated air is calculated.
4. To correctly select the cross-sectional diameter of the pipes, an aerodynamic calculation of the heating system is performed.

The calculation methodology is based on the basic requirements of SNiP. When choosing a furnace or electric air curtain, it is important to pay attention to the appropriate power of the equipment. When purchasing, you should also take into account such disadvantages as noise during operation and energy consumption. Heating of rooms with warm air can be done using recuperators; they will heat the room using a small amount of electricity.

Most heating systems that are used to heat homes have a large number of disadvantages. For this reason, many building owners prefer to look for alternative options. In particular, install air heating in a private house with your own hands. With the help of such systems, you can effectively heat both large rooms and small country houses.

Operating principle and varieties

The air heating system provides special thermoregulation. First, the air must be heated to the desired temperature, and then this heat is transferred into the room. Heating a house with warm air is good because there is no need to install special devices.

This technique first appeared in Canada, where frame-type houses are widespread, and is mainly used for heating them. Unlike brick buildings, such structures are not able to retain heat from radiators. And thanks to air heating, a good microclimate is created, and the costs for it will not be high. The system is divided into two varieties - natural and forced. In the first case, the air circulates in this way:

The house is heated as long as the boiler is running. And for a forced system, an external energy source is needed that will provide the required intensity of air circulation. The key heating unit is the fan placed under the heater. It will receive water, then it will be cleaned of germs and blockages. Through the fan grilles, air will enter the air ducts, and it will be warm inside. If an air conditioner is installed, the air ducts will need to be insulated to prevent condensation from accumulating.

Advantages and disadvantages

Now they are just gaining popularity. Before you try one or another option, you need to familiarize yourself with its features, advantages and disadvantages. Both professionally installed and homemade air heating has the following advantages:

Air heating is reliable and durable. With a properly designed design and correct installation, as well as regular maintenance, the system will last without problems for 20 years or longer. The heating rate is also high.

If the room temperature reaches zero or below, then when you start the equipment in full warm-up mode, the space will be heated for about half an hour.

But the solution also has its drawbacks. These include:

• the heating system must be installed at the stage of building the house;
• the need for regular maintenance;
• modernization in the process of using equipment is problematic;
• The equipment depends on electricity; if it goes out, the system will not work. For this reason, it is necessary to provide a backup power source;
• the need for additional air humidification and filtration.

However, most problems can be solved. But we must not forget that additional equipment and maintenance are also a significant expense item.

Economical air heating of a private house

Required equipment and heat sources

To install the system in your home yourself, you should purchase special equipment. Without it, it will not function. You will need to buy the following:

Three types of heat sources can be used to operate an air heating system. The first is “soil-to-air”, which uses soil below the freezing level, which maintains a high temperature throughout the year. Moreover, the deeper the burial, the higher the temperature will be. When a horizontal collector and deep probes are immersed, such heat can be used for heating regardless of the season.

The next type is “air-to-air”, represented by duct air conditioners. The heat pump releases hot air and then moves it through interconnected ducts throughout the home. And the third source is “water-air”. It is used for shallow groundwater. You will need to dig a well into which a heat exchanger in the form of a probe is lowered. But an important condition is the presence of a non-freezing reservoir in the neighborhood.

For the system to function properly, all calculations must be performed correctly. The accuracy of the data is influenced by factors such as:

When making calculations, it must be taken into account that heat loss should be calculated for each room separately. And an aerodynamic calculation should be performed for the entire system. Depending on the calculated heat losses, one or another type of air heater and its power are selected. The amount of air received depends on the power of the heating device.

After receiving the calculations, you can begin arranging air heating at home with your own hands. First of all, a diagram is drawn up of how the air ducts will be located and how they will be connected to each other.

Even if a person has experience in installing such systems, it is best to invite a specialist for advice on choosing a heat generator model. If the installation is very large, then it is better to install it not in the house, but in a nearby room, if available.

Systems can be of two types - mobile and stationary. Stationary systems primarily operate on gas fuel and are installed in separate rooms. They are mainly designed for heating large buildings. And mobile installations are suitable for small houses and cottages. They have an isolated combustion chamber and must be located in places where there is a built-in chimney system.

DIY air heating system you can do this:

Recently, owners of private households prefer to install air heating systems.

The equipment cannot be called cheap, but it pays for itself quickly, and in addition, compared to simple batteries, heating occurs much faster. By installing it yourself, you can save large sums of money.

If the owner of a private house or cottage wants to install a heating system using hot air for the first time, then he must weigh all its pros and cons. And if you can install everything yourself, then it is better to perform the calculations with the help of experienced consultants. Experts recommend the following to beginners:

• Distributing air vents are best connected using reinforced adhesive tape based on aluminum;
• pipes should be attached to the ceiling with clamps;
• supply air vents should be installed as close to the floor as possible;
• even if there is an air conditioner, all pipes must be insulated so that moisture vapor does not settle;
• if air intake hoses with numerous elbows or different lengths are used, then additional dampers will be required;
• An additional cleaning filter may be required;
• For additional cooling, you can use the evaporative unit of the air conditioner.

For the system to work fully, it is better to plan it at the stage of building a house. In this way, you can determine exactly where its elements will be located, and make special niches in the walls for the purpose of air vents. It is more difficult to provide for everything in a finished house. In this case, the air vents can be hidden using false walls or suspended ceilings.

Now there are a large number of alternative heating sources, in addition to the classic one. Moreover, in some cases they are more environmentally friendly and more economically profitable. Air heating of buildings is an option that can be called one of the most promising.

In order to equip a reliable, high-quality and, very importantly, economical heating system in a private house, you can use air-type heating. Air heating in a private house will significantly simplify the operation of the entire system and will create a favorable microclimate in the room.

How to choose such heating largely depends on a number of criteria. However, this heating option has already proven its performance and high performance in practice, which is why it has gained comparative popularity among consumers.

The most common is the air heating system for a home, since this option is not only quite affordable in terms of cost, but also has good performance and efficiency. The design of such a system includes the following set of functional elements:

• a heat generator, which is a heater running on water. This device is the main one in the process of heating indoor air;
• special branched channels called air ducts. They are designed to direct heated air to the desired room;
• equipment like a standard fan, which is directly responsible for transferring heat to the desired area of ​​the room.

The operating features, as well as the technical characteristics of such a procedure as air heating of a house, will be discussed further.

Pros and cons of air heating in a private house

Among the undeniable advantages that air heating systems have for a private home, the following must be highlighted:

• very high work productivity (about 90%);
• the entire design excludes the presence of any additional heating elements such as radiators, pipes, etc.;
• air heating systems can be connected to climate control systems, this is especially important for residential premises, as this makes it possible to maintain the desired comfortable temperature in the room;
• Thanks to the low inertia, you can efficiently heat the room very quickly.

But there are also some disadvantages in such systems, the most obvious of which are:

• the air heating scheme involves the installation of this communication exclusively at the construction stage of a private structure;
• for high-quality operation, such a system requires constant attention from the owners and proper maintenance;
• the principle of operation of air heating is designed in such a way that in order to function it requires constant electrical power, which, in turn, explains the need for a mandatory backup power supply point;
• During operation, it will not be possible to improve such a system in any way.

In addition, it should be noted that any drafts occurring in the room can disrupt the normal circulation of warm air in the room, which inevitably leads to overheating of the space under the ceiling and cooling of the area of ​​the room near the floor.

In a forced circulation system, it is necessary to have a fan, which, by means of pressure, directs the heated air flows entering through the air ducts. Installation of such a fan is carried out under the combustion chamber, which is equipped with air heating boilers (read: “How to use an air heating boiler - options for heating with warm air”). This device is designed to clean the air entering it from dust particles and other harmful substances and transfer the already purified flow to the heat exchanger.

Directly after the heat exchanger, air heated to the required temperature enters the room, after which it is returned back to the system through the ventilation system through the return air ducts.

How to correctly calculate an air heating system

Correct calculation of the air heating system must be carried out taking into account the following parameters:

• air heater power indicators. This parameter should be such that the room is heated normally even taking into account all heat losses;
• the speed at which heated air is transferred;
• the volume of heat loss through window and door openings, as well as through walls and ceilings;
• diameter that the air ducts have. It is important to perform an aerodynamic calculation to determine how much warm air is lost. Read also: "".

If the heating system is calculated incorrectly, this can cause the following problems:

• significant overheating of the coolant;
• unpleasant noise and knocking during operation;
• draft appearing in the rooms.

Installation principle of an air heating system

The heat generator in such a system can be either a standard electric heater or a heating boiler that runs on both gas and solid fuel.

If the heat generator is a solid fuel boiler, it is very important that it be equipped with a function for regulating the speed at which the heat source will burn. If a gas boiler is used, it must be equipped with an automatic on and off system, as well as a fuel temperature control function so that this indicator does not exceed the limits of the designated parameter.

All necessary installation materials, such as an air valve for heating, dampers, air ducts and other elements, must be purchased in advance and ready for installation.

The video shows one of the options for an air heating system in a private house:

It is safe to say that such an air heating system can be installed in any room; it is only important to strictly follow all the standards for its installation and take the installation process seriously. If any difficulties arise, you can always seek the help of professional specialists who will tell you how to properly equip air heating radiators, as well as provide various photos of these products and help you understand the features of their connection to the system.

Air heating (AH) is a common practice in private households. Such systems allow you to heat a room autonomously, cool it if necessary, control the microclimate and provide high efficiency indicators. To decide whether you should decide to install such a system or opt for steam heating, let’s look at the principle of operation, types, scope, positive and negative aspects of operation, features of design and installation.

Principle of operation

The simplest example of an air heating system for a private house is an ordinary Russian wood-burning stove. To cook dinner and heat the room, you have to stock up on firewood and light the stove. The air around the stove gradually heats up and spreads throughout the room, thereby warming up the entire home.

Natural gravitational circulation is based on simple laws of physics: warm air is lighter, so it tends to rise, cold air sinks.

The principle of operation of an air heating system is quite simple: a fan blows cold air, it is heated by a burner and then distributed throughout the house.

However, this heating principle implies natural air circulation. Modern systems operate with forced supply of hot air. The flow is supplied using pumps and fan elements. Ducts carry warm air to all rooms of the house and heat them. As it cools, the cold air drops to the floor where it enters the duct opening and the cycle begins again.

Circulation methods

Air circulation can be carried out in several ways:

• with the inclusion of fresh air in the cycle (recommended);
• without external air supply (closed cycle);
• direct flow circulation - in this case, cold air is removed outside, and a new portion is also received from the street.

Where is VO used?

Diagram of air movement in the air heating system of a frame house, where the air duct is installed in hollow walls.

Air heating is recommended to be installed in frame-type private houses. Since the design of such a house provides for the presence of voids between the outer cladding and the inner covering, the air duct system can be installed in the hollow spaces of the wall without affecting the decoration of the house.

Another option for installing an air system is to include it in the project of a future construction. So, when erecting walls, technical niches are left between them for further installation of the system. If you plan to install air heating in a finished building without such preparations, you will have to launch large-scale construction and rebuild the walls.

Design and types of air heating in private homes

Most often, an air heating system for a private home has the following components:

• heat generator - usually its role is played by a water heater, which is responsible for heating the air;
• air ducts to ensure the supply of warm air to the room;
• fan to set the direction of air flow indoors.

VO systems are formed according to gravitational or forced schemes.

Gravity diagrams

The natural or gravitational scheme implies that warm air circulates due to its density changing as its temperature changes. The main advantage of this type is that the system operates almost autonomously from the electrical network. However, due to disadvantages, the range of use of this approach is limited.

Work can be disrupted by a draft or an influx of cool air from the street, which will result in excessive heating of the air near the ceiling and strong cooling of the main part of the room.

Forced schemes

The main difference between a forced system is the presence of a fan that regulates the direction of air flow. The heat generator heats the air, the fan creates pressure and directs the mass through the pipes. Such ventilation systems are installed under a heater, into which air purified from dust and foreign odors is supplied. After the heat exchanger, the air is directed into the air ducts, and its return is provided by return air ducts or ventilation grilles.

Advantages and disadvantages of air heating

To make a choice, consider the features of using such systems in private homes:

Heating of a private house, the fireplace acts as a heating element.

1. Estimated service life is 30 years. Usually, after a couple of years, the costs of VO are fully repaid to the owners.
2. No leaks or risk of pipe freezing, high efficiency, no intermediate transmission elements and low energy consumption.
3. Fans can “cooperate” with a conventional stove and supply warm air to all rooms. A well-known example is fireplace air heating of a private house.
4. Filters and ionizers can purify the air of odors and eliminate harmful particles.
5. The system creates an optimal microclimate, producing additional air humidification or drying, depending on the characteristics of the climate and the room.
6. In the summer, you can cool the room using air ducts with additional draft that supply cool air.
7. If you are not at home, the system operates at a minimum and quickly increases the temperature when necessary.
8. The main disadvantage is the need for power supply to the forced circulation system and the need for backup power if power outages are expected.
9. Support for installing the system is laid only during the construction of a building or complex repairs are carried out with subsequent installation.
10. VO is quite demanding in terms of repair and maintenance; with regular use, it is difficult to carry out a full modernization.

How to draw up a heating project

If you decide to install a VO system, it’s worth understanding and developing a detailed project. Key points to consider when planning:

• heating speed (warm air supply) and room area;
• heat generator power, which is calculated based on the characteristics of the house and possible heat losses (condition of doors, windows, walls);
• dimensions of air ducts and the subsequent value of air pressure losses.

Please note that for optimal operation of the system, all calculations are carried out by competent specialists. Due to miscalculations and attempts to independently “figure out” the operation of the system, intense heat loss, strong noise and vibration during operation are possible.

The principle of installation of air heating

Air heating of a private house is installed in voids in the walls and floor, and this improves the appearance of the house, eliminating the need for various pipes and radiators.

The elements of the system are installed mainly in free cavities in walls and floors, which significantly improves the room. However, their installation must be planned before the construction stage of the house or significant redevelopment must be carried out. To heat the room, special grilles are installed on the walls to supply warm air and take in cold air. If the project provides for functional additions, then the VO can fit into the air conditioning system and be combined with ventilation. The equipment itself can operate from different power sources: gas, coal, electricity. For the rest of the installation, VO determines an individual work plan.

One of the features of the system is that it is almost impossible to build air heating for a private house with your own hands, unless, of course, you have a sufficient technical base.
