Estimate of the air heating system of the industrial premises. We consider air heating of industrial premises - calculation and scheme. Features of water heating

Heating a production facility is no easy task. The thing is that, unlike residential buildings, such objects are usually built under some kind of technological process, and their dimensions are impressive. So, quite often there are even such industrial premises, the dimensions of which are several thousand square meters. And the height of the ceilings is 20-25 meters. However work zone, which really needs heating is often only 2 square meters. So how to heat such an industrial room?

Should traditional methods be used here - air or water heating? Coefficient useful action for such systems, when used in huge workshops, will be minimal, and is unlikely to give desired effect. But the cost of their maintenance will be simply unbearable for the enterprise, and hundreds of meters metal pipes quickly covered with rust. But which option then to choose, or leave the production workshops without heating at all?

Which autonomous heating of the industrial premises to choose

But first you need to decide on the types industrial premises, their characteristics and functions. So, most often there are warehouses, workshops and actually industrial buildings. When choosing efficient heating The features of such systems should be taken into account, which include:

maximum efficiency;
the possibility of heating rooms with large areas;
heaters should, if possible, heat the air both inside and outside.

In addition, the choice desired system, as a rule, such factors as the specifics of the production process and the cost of equipment, as well as much, much more, also influence. Next, we will consider in more detail the pros and cons of each possible option.

This type of heating is quite often used in industrial buildings. It has both its advantages and disadvantages. The first ones include:

constantly high air temperature - from 100 degrees and above;
how to heat and cool the room after work as quickly as possible;
the number of storeys of the object does not matter, since steam heating can be equipped in a building with any number of floors;
Not big sizes main pipeline and heating equipment.

This perfect option in order to heat production periodically. Moreover, such systems are better suited for industrial facilities than heating using water as a heat carrier.

The disadvantages of this type of heating include:

strong noise during operation;
it is extremely difficult to control the steam flow, and, consequently, the heat transfer.

Depending on the choice of fuel, such an installation can now cost from 32,000 to 86,000 rubles for a medium-sized industrial enterprise with a total area of up to five hundred square meters and a ceiling height of up to three meters. However, steam heating should not be used in facilities where combustible gases, dust and aerosol are released into the air.

Water heating systems for industrial premises

In this case, the local boiler house of the enterprise or even district heating. At the same time, the main element of such a system is a special boiler that runs on gas, electricity or solid fuel. Of course, it is best to choose gas or coal as the latter, but the latter option will be somewhat more expensive. Other types of fuel will cost the organization much more, and therefore it is hardly advisable to use them.

Features of water thermal installations

When using water as a heat carrier for heating a building, the following features of such systems should be taken into account:

constant high pressure;
high temperatures;
are used mainly for moderate heating of objects (the average temperature should be kept at plus ten degrees), if this, of course, does not harm the production process.

Such heating can be made both local and centralized; and it is distinguished by the following features:

air masses are constantly in motion;
the air is regularly changed and cleaned;
more evenly distributed throughout the rooms and temperature;
harmless to humans.

Heated air enters the workshop through air ducts, where it is moved with the existing one. And most of it then passes through special filters, is heated again and used. Thus, energy losses are minimized. In addition, such a system provides an air supply from the outside, which already meets sanitary standards. However, if during the production process itself some harmful substances, then such a recycling system is unlikely to be effective and safe. In this case, you will have to completely remove all the air that comes out.

Note that when using local air heating, the heat source is located in the center of the building. BOA is usually taken as the latter, heat guns etc. However, only the air inside can be treated this way, and fresh air masses will not come in.

Air solar collector

Heating systems using electricity

If the size of the production room is small, then maximum comfort for workers can be achieved using electric infrared emitters, which, by the way, are often installed in warehouses. However, the main devices for such systems are still the so-called thermal curtains. We add that the cost of heating with electricity costs the company about 500,000 rubles per season.

Ceiling systems

Ceiling heating systems are very popular now. Moreover, special radiant heating is widely used not only in production facilities, but also in greenhouses, conservatories, and even in residential buildings. Such heating differs, first of all, in that not only the air in the room is heated, but also the floor, walls, and even all objects located in the building. Note, and other advantages of ceiling systems:

long service life;
little space is required to accommodate them;
the equipment weighs little, and its installation is simple;
suitable for any space.

Experts believe that such systems should be used at facilities with insufficient use of electricity. A noticeable plus is also considered the speed of heating the room. And if this factor plays a decisive role, radiant panels are ideal for a production room.

How to choose the right heating scheme

However, no matter how good ceiling systems radiant heating, it will be problematic to use them for Soviet-era buildings. The thing is that the buildings of that time already had large heat losses. Therefore, for such objects, they often choose more economical option, for example, using alternative fuel. However, when choosing a specific scheme, one should also take into account the fact that there are SNiP norms for heating industrial premises:

the project should be done taking into account the heat costs for heating air, equipment and objects, as well as other heat losses; moreover, the latter can be no more than 3 degrees of difference between the air temperature inside and outside the room;
permissible parameters of the coolant used - 1.0 MPa of pressure and plus 90 degrees of temperature;
it is preferable to use water as a heat carrier if it is not possible to justify the use of other liquids;
when heated by electricity, the entire facility must meet the relevant requirements;
as a rule, landings are not heated;
gas equipment is used only when the products of gas combustion are removed in a closed way.

Today, many commercial and industrial organizations face the issue of cost savings. In winter, heating a production facility with a constant increase in electricity prices can cost a pretty penny, so the demand for effective ways heating - first of all, direct heating of air using the cheapest fuel today - natural gas. Systems air heating industrial and commercial premises offered by our company are among the most efficient, profitable and advanced on Russian market. Let us consider the main characteristics of such systems.

Features of air heating systems

For industrial premises requiring heating and ventilation, systems are used in which air is supplied to the premises through air ducts. It is most expedient to use such systems if it is necessary not only to heat, but also to ventilate and / or air-condition the room - since in this system it is possible to combine all these functions. A similar system is mounted using large industrial units, usually located on the roof. This is how the heating, ventilation and air conditioning system is built in large shopping malls, office buildings, as well as production workshops. The system allows you to maintain the desired climatic parameters in the room - temperature, humidity, purify the air from microbes, dust and other harmful impurities, creating the most favorable environment for people in the room. If the task is only to heat the production premises with minimal cost, then the most optimal way is to install local gas air heaters. This is a compact and inexpensive equipment operating on the principle of a fan heater. Local air heaters are controlled by thermostats that regulate the temperature in the room and give a signal to turn on if it drops to a certain value. In both cases, the heating system of an industrial or warehouse space has several undoubted advantages:

use of a cheap energy source (gas)
the absence of an additional coolant, as well as the bulky system associated with it (pipes, boilers, pumps)
exceptionally low inertia - no time is required for heat transfer from the coolant to the battery, the heated air immediately enters the room
exceptionally high efficiency - up to 93%
creation of a more even distribution of heat due to the constant circulation of air in the room

Implementation of an air heating system in production

Design and installation of air heating systems is a task for professionals in this field, requiring to take into account a lot of nuances. This is the calculation of power and the selection of optimal equipment, taking into account heat losses in a particular room, aerodynamic calculation and many other parameters. Errors at the design stage can lead to unsatisfactory functioning of the system, the appearance of undesirable side effects - for example, excessive noise in the room, imbalance in the distribution of air flows, stagnation of air, or vice versa - the appearance of drafts. Only after all the features of the production premises and the wishes of the customer are taken into account and agreed upon in the form finished project, the company's engineers begin the supply and installation of equipment and air duct systems.

Operation of air space heating systems

Air heating system production shop or storage space must be equipped automatic devices protection and regulation. Before handing over the system to the customer, the contractor performs commissioning, checking all parameters of the system and its safe operation. Regular maintenance of the system is an important component of its long, efficient and trouble-free operation. As a rule, the specialists of our company are engaged in regular maintenance installed systems. Remember - even such "little things" as an untimely filter replacement can lead to a serious deterioration in performance. Before everyone heating season it is necessary to carry out a complex of preventive works, including checking the equipment and the air duct system.

Industrial premises, workshops, warehouses, due to their spacious size and taking into account the climatic conditions of Russia, often need to solve such topical issue, How optimal heating. The word "optimal" means the price/reliability/comfort ratio that is appropriate for an industrial building.

That's what we'll talk about in our article.

In general, creating a heating scheme for industrial premises is a rather difficult task. This is due to the fact that each individual production facility is built for specific technological processes, and has a very large size and height.

Plus, the equipment that is used in production sometimes complicates the laying of pipes for ventilation or heating. But despite this, heating industrial buildings- an important function, without which it is impossible.

And that's why:

thoughtful heating system provides comfortable conditions labor for employees and directly affects their performance;
it protects equipment from hypothermia, which can cause damage, which in turn will lead to monetary costs for repairs;
warehouses must also have an appropriate microclimate so that the goods produced retain their original appearance.

Note!
By choosing a simple, but at the same time reliable heating system, you will reduce the cost of its repair and maintenance.
Plus, to control it, it will take much fewer employees.

Choosing a heating system for industrial premises

For heating industrial buildings, central heating systems (water or air) are most often used, but in some cases it is more rational to use local heaters.

But in any case, when choosing a production heating system, you need to rely on the following criteria:

The area and height of the room;
The amount of heat energy needed to maintain optimal temperature;
The ease of maintenance of heating equipment, as well as its suitability for repair.

And now let's try to deal with the positive and negative sides that the types of heating of industrial premises mentioned above have.

Central water heating

The source of the heat resource is the central heating system, or a local boiler house. Consists of water heating from the boiler, (radiators or convectors) and pipelines. The liquid heated in the boiler is transferred to the pipes, while giving off heat to the heaters.

Water heating of industrial buildings can be:

Single-pipe - here it is impossible to regulate the water temperature.
Two-pipe - here temperature control is possible and is carried out thanks to thermostats and radiators installed in parallel.

As for the central element of the water system (that is, the boiler), it can be:

gas;
liquid fuel;
solid fuel;
electric;
combined.

You need to choose based on the possibilities. For example, if it is possible to connect to a gas main, a gas boiler would be a good option. But keep in mind that the price of this type of fuel increases every year. Plus, there may be interruptions in the central gas supply system, which will not benefit the manufacturing enterprise in any way.

Requires separate safe room and fuel storage tanks. In addition, you will have to regularly replenish fuel reserves, which means taking care of transportation, unloading - additional costs. Money, labor force and time.

Solid fuel boilers are hardly suitable for heating industrial premises, except perhaps small ones. The operation and maintenance of a solid fuel unit is a rather laborious process (fuel loading, regular cleaning of the furnace and chimney from ash).

True, at present there are automated solid fuel models that do not need to be loaded with fuel with your own hands; a special one has been developed for this. automatic system fence. Also, automated models allow you to set the desired temperature.

However, you still have to take care of the firebox. Pellets, sawdust, wood chips are used here as fuel, and when manually laying, also firewood. Although this type of boiler involves labor-intensive operation, it is the most inexpensive.

Electric boilers are also not the best option for big industrial enterprises, since the spent electricity costs a decent "penny". But the heating of industrial premises of 70 square meters in this way is quite acceptable. However, do not forget that in our country, periodic power outages for several hours are a common occurrence.

As for combined boilers, they can be called truly universal units. If you have chosen a water heating system and want to get efficient and uninterrupted heating of production as a result, then take a closer look at this option.

Although the combined boiler costs several times more than the previous units, it gives a unique opportunity - to practically not depend on external problems (interruptions in the centralized heating system, gas supply and electricity supply). Such units are equipped with two or more burners, for various kinds fuel.

Built-in types of burners are the main parameter for dividing combined boilers into subgroups:

Gas-fired heating boiler- you can not be afraid of interruptions in gas supply and rising fuel prices;
Gas-diesel- provide high heating power and comfort in a large area;
Gas-diesel-wood- has extended functionality, but it has to be paid for with lower efficiency and low power;
Gas-diesel-electricity- a very effective option;
Gas-diesel-wood-electricity- improved unit. It can be said that it provides complete independence from possible external problems.

Everything is clear with boilers, now let's see if water heating in production fits the selection criteria that we initially outlined. It should immediately be said that the heat capacity of water, compared to the heat capacity of the same air, is several thousand times greater (at normal air (70°C) and water (80°C) temperatures in the heating system).

In this case, the water consumption for the same room will be thousands of races less than the air consumption. And this means that less connecting communications will be required, which, of course, is a big plus, given the design of industrial premises.

Note!
The water heating system allows you to control the temperature: for example, you can set the on-duty heating of production (+10 ° C) during non-working hours, and set a more comfortable temperature during working hours.

air heating

This type is the very first artificial space heating. So air heating systems have been proving their effectiveness for quite a long time and, it should be noted, are in constant demand.

All this thanks to the following positive aspects:

Air heating assumes the absence of radiators and pipes, instead of which air ducts are installed.
Air heating shows more high level Efficiency compared to the same water heating system.
The air in this case is heated evenly, throughout the volume and height of the room.
The air heating system can be combined with the system supply ventilation and conditioning, which allows you to receive fresh air instead of warm.
It is impossible not to mention the regular change and cleaning of the air, which has a beneficial effect on the well-being and performance of employees.

In order to save money, it is better to choose combined industrial air heating, which consists of natural and mechanical air induction. What does it mean?

The word "natural" means the intake of already warm air from environment (warm air everywhere, even when it's -20°C outside). Mechanical impulse is when the air duct takes from the environment cold air, heats it up and delivers it to the room.

For heating a large area, air heating systems for industrial premises are perhaps the most rational option. And in some cases, for example, in chemical plants, air heating is the only permitted type of heating.

infrared heating

How to heat a production room without resorting to traditional methods? With the help of modern infrared heaters. They work according to the following principle: emitters generate radiant energy over the heated area and transfer heat to objects, from which the air is heated in turn.

Information! The functionality of infrared heaters can be compared with the Sun, which also heats the earth's surface with the help of infrared waves, and as a result of heat transfer from the surface, air is heated.

This principle of operation eliminates the accumulation of heated air under the ceiling and, as a result, large temperature drops, which is very attractive for heating industrial enterprises, since most of them have high ceilings.

IR heaters are divided into the following types according to the installation site:

ceiling;
floor;
wall;
portable floor.

By type of emitted waves:

shortwave;
medium wave or light (their operating temperature is 800 ° C, so during operation they emit soft light);
longwave or dark (they do not emit light even at their operating temperature 300-400°C).

By type of energy consumed:

electrical;
gas;
diesel.

Gas and diesel infrared systems are more profitable and their efficiency is 85-92%. However, they burn oxygen and change the humidity in the air.

By type of heating element:

Halogen- the only drawback is that if dropped or hit hard, the vacuum tube can break;
Carbon– the main heating element is made of carbon fiber and placed in a glass tube. The biggest plus compared to other IR devices is lower power consumption (about 2.5 times). When falling or strong blow possible breakage of the quartz tube.
Shadow;
Ceramic– the heating element is made of ceramic tiles assembled into one reflector.
The principle of operation is the flameless combustion of the gas-air mixture inside ceramic tiles, as a result of which it heats up and transfers heat to surrounding surfaces, objects, people.

IR heaters are most often used for heating:

industrial premises;
commercial and sports facilities;
warehouses;
workshops;
factories;
greenhouses, greenhouses;
livestock farms;
private and apartment buildings.

Advantages of infrared heating:

First of all, it should be noted that IR heaters are the only type of devices that allow zone or spot heating. Thus, in different parts production facility can support various temperature regime. Zone heating can be used to heat workplaces, parts on a conveyor, engines in a car, young animals on livestock farms, etc.
As mentioned above, IR heaters heat surfaces, objects and people, but do not affect the air itself. It turns out that there is no circulation of air masses, which means that there is no loss of heat and drafts and, as a result, there are fewer colds and allergic reactions.
The low inertia of infrared heaters allows you to feel the effect of their action immediately after starting, without preheating the room.
Infrared heating is very economical due to its high efficiency and low power consumption (up to 45% less energy than traditional methods). Probably, it is not necessary to explain that this significantly reduces the financial costs of the enterprise and quickly pays off all the funds invested in infrared heating.
Infrared heaters are durable, lightweight, take up little space, they are easy to install (each product comes with detailed instructions for installation) and they practically do not require Maintenance during operation.
Infrared heaters are the only type of heating devices that can provide effective local heating (that is, without resorting to centralized systems heating).

Finally

Finally, I would like to suggest that you familiarize yourself with the photo table, which indicates the specific heating characteristic industrial buildings.

We examined the main types of heating industrial premises. Which will be the most optimal in your case - it's up to you. And we hope that this article has become useful for you. You will find additional information on this topic in a specially selected video material.

For comfortable work employees of production and storage facilities need to equip an efficient heating system. In addition, the normal temperature regime has a positive effect on equipment, machines and the building itself. Consider what are the ways of heating production and storage facilities. After all, someone chooses heating boilers, and someone prefers heaters for space heating. In our article we will talk about the features and effectiveness of work different systems heating.

How to heat non-residential premises

For rooms with large areas, 3 types of heating systems are usually used: air, water and radiant. When using water heating, it is necessary to arrange heating radiators. Such a system is beneficial, as it has a large selection of heating equipment. But with such a heating system, there is a large thermal inertia and high costs are required. Not all commercial premises can be equipped with heating radiators, as they must be installed on the wall. And usually in retail outlets in these places they arrange racks.

Radiant and air heating have a higher demand. Consider in detail each heating system.

air heating

Air heating appeared one of the first types of heating systems. And until now, such a system is popular due to its effectiveness. Air heating has the following advantages:

In such a system, the efficiency is greater than that of water heating.
There is no need for piping and heating radiators. In the air system, it is necessary to install only air ducts.
An air heating system is often used in conjunction with an air conditioning system. Therefore, you can get clean air instead of heated.
The heated air is distributed evenly throughout the room.
The air is cleaned and changed regularly. Therefore, there will always be a comfortable atmosphere in the room, which positively affects the performance of employees.

In order to save money, it is better to use combined air heating for industrial premises. Such a heating system consists of mechanical and natural air induction.

With natural intake, warm air will be taken from the environment. It will be warm even when it is very cold outside. Mechanical impulsion - cold air intake by an air duct for heating and supply to the room.

Air heating is the most optimal for heating large industrial premises. And in chemical enterprises, only air is allowed to be used as a heating system.

Water heating

Not all production and storage facilities are suitable for a water heating system. Since for its device it is necessary to equip a boiler room, arrange a piping system, install heating radiators in the premises. In addition to these elements, you still need to purchase pressure gauges, stop valves and other control devices. In order to maintain the operation of the heating system, the presence of specialists is necessary.

Water heating is of two types according to the principle of the device: one-pipe and two-pipe.

In the first type, it will not be possible to regulate the water temperature. Since all heating radiators are installed in series. And there is no way to turn off only one device.

In a two-pipe system, the temperature can be controlled. This can be done using thermostats that are installed on radiators in parallel.

The heating boiler serves as a source of heat in the water system. Boilers are divided according to the type of fuel: solid fuel, gas, electric, liquid fuel and combined. If the production facility has small area, then you can use a furnace with a water circuit.

The type of boiler should be chosen from the desires and possibilities. Not everyone has the ability to connect gas, so a gas boiler cannot be used. Many people choose solid fuel or diesel heating boilers.

Electric boilers are often used, but in small rooms. Since heating with electricity is not cheap.

Unforeseen situations often happen. And there may be any accidents in the electricity or gas supply. Therefore, it is desirable to have a backup version of the heating system.
Combined heating boilers are more expensive. Such devices can have several types of burners: gas-diesel, gas-wood and gas-electricity-diesel.

infrared heating

Infrared heating can be divided into two types: light and dark heaters.

In the first form, the gas is burned with a burner. And its surface temperature can be 900oC. The required radiation comes from a hot burner.

The second type of heater is radiators with reflectors. They are designed to direct radiant energy to the required areas. Dark infrared devices cannot heat up like light ones. Maximum temperature heating is 500°C. Such heaters differ in radiation, it is not so hard. Therefore, tubular heaters have a large scope.

The most convenient and economical heating is a suspended radiant panel. Such panels work with the help of an intermediate coolant. It is made up of steam and water. Water can be heated in the device up to 60-120 ° C, and steam is heated up to 100-200.

Consider the benefits of radiant heating:

Warm zones can be created in unheated rooms;
Rapid space heating. Depending on the area, the approximate heating time is from 15 to 20 minutes;
Since there is no need to check or repair pumps, replace filters and other elements that are in other heating systems, this factor allows you to save a lot;
No loss of thermal energy;
The floor is also heated, so it is an additional source of heating;
Comfortable microclimate. The air does not dry out

Such heaters cannot be installed indoors: with a ceiling height of less than 4 m, in production, where radiation can affect the quality of products, as well as in rooms that have fire categories A and B.

The infrared heating system is easy to use and more economical than an air system. Infrared heaters do not spread dust, do not dry the air and create thermal zones in the room. But in those rooms where it is impossible to use radiant heating, the best option there will be an air system.

The organization of the production process is a multifaceted task in which all factors must be taken into account. In addition to equipment and skilled workers, attention should be paid to Special attention maintaining the optimum room temperature. To do this, you need to develop systems and schemes for heating workshops with your own hands: welding, carpentry, production.

The choice of heating according to the characteristics of the room

Before you do the heating of the workshop with your own hands, you need to find out several important characteristics. First of all - the optimal temperature regime in the room. The choice of heating system directly depends on this.

When drawing up a heating scheme for a carpentry shop or other production areas, the following parameters must be taken into account:

Ceiling area and height. If the distance from the floor to the roof is more than 3 meters, then convection (water, air) systems will be ineffective. This is due to the large volume of the room;
Thermal insulation of walls and roofs. Heat loss buildings are the first thing to consider when choosing. The heating system for the workshop should be not only efficient, but also economical. In this case, it is best to use zonal heat sources. They will maintain a comfortable temperature level in a certain area of \u200b\u200bthe room;
Technological requirements for optimal temperature in the workshop. For example, the heating of a woodworking shop must maintain the heating of the air at a constant level. Otherwise, it will affect the quality of the products. If the raw material is metal, then comfortable temperature needed only for workers.

To conduct this analysis, it will be necessary to study the advantages and disadvantages of each type of heating. Consider the most efficient heating of the production hall, which differs depending on the scheme and the components used.

Air heating of the workshop

For large rooms with high temperature requirements, it is recommended to use air heating of the workshop. This system is an extensive network of air channels through which hot air flows move. Its heating occurs with the help of a special climate control unit or a gas boiler.

Such do-it-yourself systems and schemes for heating workshops are applicable for welding, carpentry, and industrial premises. Main structural elements of this system are:

Outdoor air intake device. It includes fans and cleaning filters;
Further, the air masses through the channels enter the heating zone. It can be electrical appliances (spiral element) or gas installation with air heat exchanger;
Air masses with high temperature move along channels that distribute heat to individual production rooms. To control the heating temperature level, a throttle valve is installed in each outlet pipe.

Such a shop air heating system has a number of significant advantages over the standard one. The main one is the optimal heating of the room. Properly positioned air ducts can have directional elements that focus airflow to the desired area of the shop.

Also at additional installation air conditioner, the same system can be used as a cooling system. However, such a scheme for heating the workshop is rather complicated in terms of design. Before self-installation you need to calculate the power of the fans, the shape and cross section of the air channels. Therefore, for the installation of air heating of the production workshop, it is recommended to use the services of specialized companies.

Workshop water heating

The use of traditional water heating is relevant for small industries whose workshop area does not exceed 250 m². It is necessary to constantly maintain the air temperature at an optimal level throughout the volume of the room. Often, woodworking shops are heated with water.

This is due to wood waste production. For their disposal, a solid fuel boiler is installed. long burning. This scheme of work allows not only quickly, but also effectively get rid of wood waste. Later they are used as fuel.

However, this scheme for organizing heating has a number of nuances:

In order to maximize the heating efficiency of the production workshop, it is necessary to significantly increase the area of heating devices. Pipes are used for this. large diameter, which are welded together into registers;
Inertia. It takes a sufficiently long time to heat the air in the workshop from the coolant;
The inability to quickly change the temperature of the water in the pipes.

However, along with this, when installing water heating in the welding shop, a floor heating system can be used. Such a scheme will help reduce the required area of \u200b\u200bheaters. At the same time, the inertia of the system will decrease - the air in the workshop will heat up faster.
During the design of heating, it is possible to provide for the organization of hot water supply, which is important for many production processes. To do this, you need to purchase (or make) a heat exchange tank for heating the workshop with your own hands.

In it, the energy of the coolant will be transferred through the coil to the water. This will make it possible to use hot water not only for household needs, but also for production processes.

In addition to solid fuel boilers, you can install other types of heating equipment:

gas boilers. Economically effective if there is no cheap solid fuel;
Electric heaters. It is preferable not to use them, as the cost of electricity will be high;
Boilers running on liquid fuel - diesel or used engine oil. Installed if there are no gas lines. They are economical, but inconvenient in that special containers are needed for storing fuel.

To use water circuits for heating a workshop, it is necessary to correctly calculate the power of the heating installation.

The standard ratio of 1 kW of released thermal energy per 10 m² of area is relevant only for a workshop whose ceiling height does not exceed 3 meters. If they are higher, then each extra meter this is + 10% to the power of the boiler.

Workshop infrared heating

The principle of operation of infrared heaters is to heat surfaces due to the effect of infrared radiation. If the heating system of the welding shop is designed for spot heating of certain areas, then it is best to use these devices. Efficient heating infrared heaters for workshops, start with the selection of heating elements. Currently, two methods for generating IR radiation are used.

Carbon heaters

Its design consists of a bulb, inside of which there is a carbon spiral, and a reflective element. When current passes through the heating element, it glows due to high electrical resistance. As a result, IR radiation is emitted.

To focus the thermal energy, a reflector made of stainless iron or aluminum is provided.

IR electric heaters can be used as additional heating of the carpentry shop. They are mounted above those working areas where a stable temperature regime is required. The advantages of electric infrared heaters include:

Easy installation;
The ability to control the heating temperature by changing the supplied current power;
Small overall dimensions.

However, due to the high energy consumption, heating with electric infrared heaters for workshops is rare. Instead, they mount gas models.

Gas infrared heaters

For production workshops with a large area, if zonal heating is required, it is recommended to use gas models of infrared heaters. Their principle of operation is based on the so-called flameless combustion of a mixture of gas and air on a ceramic surface. As a result, IR radiation is formed, which is focused by the reflector.

For efficient heating Infrared heaters for workshops often use ceiling models of heaters. It is important to correctly calculate the mounting height and the required power. The heating area and the temperature regime in this part of the workshop will depend on these parameters.

They are used as a heating system for a welding shop, where a comfortable temperature is needed only to ensure normal conditions for the working personnel. However, when planning this type of heating, a number of nuances must be taken into account:

An infrared heating system for a workshop cannot be used if air heating is needed throughout the room. Heaters are designed for local impact;
To minimize costs, only natural main gas should be used. Liquefied bottled, in addition to the additional purchase of exchange containers, is inconvenient due to the periodic connection procedure.

But despite these shortcomings, the use of infrared heating for woodworking shops and other industries remains the best option. However, for mounting gas heating workshops only with their own hands, it is necessary to carry out a series of coordination activities with the gas service in order to obtain all permits.

How to choose the right heating system for a particular workshop? It is necessary to take into account its operational parameters, the cost of acquiring equipment and the price of an energy carrier. Remember that the cost of production will depend on the efficiency of heating of any production workshop.

If you need an economical option for organizing heating for a carpentry shop, you can see it in the video non-standard ways air heating using sawdust and wood shavings.
