How to determine air humidity in an apartment

What device measures humidity and where to buy such a meter? If the air in your apartment is too humid or, on the contrary, dry, then you need to take some measures to establish its optimal level. But first, you should familiarize yourself with how to determine and how to measure air humidity at home. There are several ways to measure air humidity.

Hygrometer

Using this device is the simplest and most reliable option.

When choosing a hygrometer, you should pay attention to its accuracy. The measurement deviation should be no more than 1%

Glass tumbler

This method is not accurate, but if necessary it will help you understand the humidity values. The necessary items to carry out such a task are probably in the arsenal of every housewife.

Procedure:

Fill a glass vessel with cold water.
Cool the contents of the glass to 3-5 degrees.
Place the vessel in the room away from heating devices and analyze the result.

Result evaluation:

The walls of the vessel fogged up, but after about 10 minutes they became dry. This result indicates an extremely low level of humidity.
The foggy walls of the glass have not dried even after 5-10 minutes and drops flow into the glass. Such indicators indicate increased air humidity.
The condensation formed on the walls of the glass container has not evaporated, but does not flow down in large drops. This effect indicates that the moisture in the air is within normal limits.

Procedure:

First, you need to measure the air temperature using a standard mercury thermometer. Record your readings.
Wrap the head of the device with damp, wet cotton wool or gauze and after 10 minutes, evaluate the thermometer readings.
Subtract the number of the “wet” thermometer from the temperature of the “dry” thermometer.
Find the resulting difference using the values of Assmann’s special psychometric table, determining the level of air humidity in the room you need.

Features of microclimate measurements

The microclimate parameters in the room are measured taking into account the actual temperature outside. Regulatory requirements depend on it. In winter, the relative humidity can be reduced to 30%, while in summer it should not fall below 35%.

In production, educational institutions, and public organizations, microclimate indicators are monitored at least 3 times a day. The peculiarities of the labor process, the presence of heating and ventilation systems are taken into account. Only by analyzing all the factors can you identify the main problems and take the right measures to eliminate them.

Carrying out measurements of microclimate parameters is necessary when assessing working conditions at an enterprise or organization. There are also programs in production, according to which the values of external factors must be measured in order to know whether they meet the requirements of the technological process.

At home, you can also control microclimate parameters. For this purpose, universal devices or separate devices are used. Pressure is measured with a barometer, temperature with an alcohol or electronic thermometer, and humidity with a hygrometer.

Traditional ways to measure indoor humidity

The importance of humidity in the home has long been known. They learned to identify deviations from the norm even when measuring instruments did not exist.

People looked after indoor plants. If the flowers dry out despite frequent watering, this indicates dry air in the room. Increased water content led to rotting.

The condition of the soil in a flower pot will quickly indicate the level of humidity

Observation of nature suggested another way of determining. It has been noticed that the spruce cone shrinks its scales when the moisture in the air increases. And vice versa, it opens completely when there is not enough water. If you attach a cone to plywood and hang it in a room, it will warn of changes in water content in the atmosphere.

Attention to detail and using the experience of ancestors will help determine the level of humidity in the house even without household appliances. An ordinary glass glass of water should be kept in the refrigerator for at least five hours.

Then it is installed on the table and after 5 minutes its walls will show the humidity level in the room. If they just fog up, then everything is fine. Running trickles will indicate an increased state. Dry - about a serious shortage

An ordinary glass glass of water should be kept in the refrigerator for at least five hours. Then it is installed on the table and after 5 minutes its walls will show the humidity level in the room. If they just fog up, then everything is fine. Running trickles will indicate an increased state. Dry - about a serious shortage.

You don’t have to buy a psychrometer, but measure the readings with one room thermometer. To do this, you need to write down the readings on paper and wrap the thermometer with damp cotton wool. After 10 minutes, take readings. How to make calculations was discussed above. But you can use the Asman table.

Ventilation grille flow measurement

The most common instruments are anemometer and hot-wire anemometer.

To simplify the process, as well as to minimize errors, it is worth using additional devices. The simplest of them is a funnel. It has a simple design that allows you to determine the air flow in just one measurement. This feature significantly saves the specialist’s time. In some cases, it is necessary to measure the air temperature in the room to obtain more accurate measurements.

It happens that they need to be produced in difficult places. In such cases, a telescopic probe is used. Thanks to its long base, you can reach difficult places and take measurements both of atmospheric air and directly in the air duct.

To simplify the procedure, it is necessary to purchase those devices that determine the flow rate through automation. The final result is displayed on an electronic display. There is no need to make additional calculations here. The device will show the average number of three measurements. In the absence of these functions, the calculation is carried out independently.

Dry air danger

The problem of dry air is especially relevant in the hot season, when the ambient temperature rises significantly. This means that dust, pollen, animal hair and other allergens easily move around the rooms and do not settle on furniture. Thus, it is easier for them to enter the human body through the respiratory tract and cause a serious reaction. This is especially dangerous for young children.

In addition, dry air causes the mucous membranes of the respiratory tract to dry out, which makes the organs vulnerable to the action of microbes. Working in a room with dry air is difficult, even for a very efficient person, as the body quickly gets tired. A person constantly experiences a feeling of drowsiness. Increased static electricity is also a characteristic phenomenon in such rooms.

How does air humidity affect the condition of apartment residents?

Accumulation of moisture on windows is the first sign of high humidity

Condensation on windows and mold indicate excessive moisture levels in the room. Fungal mold can cause many diseases, including:

bronchitis;
development of cancer;
asthma;
otitis (ear inflammation);
allergic reactions;
diseases of the cardiovascular system.

If family members begin to develop the listed diseases, you need to immediately figure out how to check the humidity in the apartment. All residents of the house may suffer from immunodeficiency and constant headaches.

Important: mold in the house can cause diathesis in infants, triggered by low immunity

Dry air is no less dangerous than excessively humid air. Water particles contribute to the settling of various allergens such as dust, pet hair and others. In dry air, allergens float freely around the room, thereby entering the body. Residents of such premises are accompanied by chronic fatigue, and infectious diseases develop faster. Children may develop kidney failure and dysbiosis.

Increased moisture

The air humidity in the apartment is measured so as not to encounter the difficulties of dry air and increased moisture levels. Some people believe that this is not a particularly serious problem, so installing a hygrometer is pointless. But this attitude needs to be changed, since there will be negative consequences if the level of humidity in the apartment is not controlled.

A relatively high level of air moisture at home is a source of microscopic fungi on surfaces. Also, such conditions are a favorable environment for the development of fungus, which can adversely affect human health. Mold can cause a person to develop allergies.

But do not forget that allergies are just one of the diseases that mold can cause in humans. The fungus can become a source of a variety of infectious diseases.

Mold spores may end up in your food. A person and his entire body may begin to suffer from foodborne illnesses. This is dangerous for all the people who live in this house.

To avoid all these problems, it is necessary to regularly ventilate the room. Ventilation should take place regardless of the temperature outside the window and at any time of the year.

You will be able to enjoy favorable home conditions due to the fact that the moisture will always be normal.

By controlling the level of humidity in the room, you will help eliminate the likelihood of mold or mildew developing on various surfaces. It will also keep your body healthy. That's why a hygrometer was created that will make your task easier. There is a fairly wide range of these devices in stores, which allows you to choose the right hygrometer for yourself.

When choosing, look at the accuracy of the device's values. Not everyone needs instruments (meters) that display ultra-precise readings of relative air humidity levels. Most buyers are satisfied with approximate values when determining. The air humidity in the room and the accuracy of the readings depend on the technical component of the meter.

First, compare the technical characteristics of a particular type of moisture detector. A device that is chosen at random will cause a lot of frustration during use and will not meet all the requirements. You will only ruin your nerves and mood and waste your money.

Therefore, after purchasing a determinant, keep the receipt for it so as not to encounter future troubles. Thanks to the receipt, the hygrometer can be returned to the store if it does not meet your requirements. Buy a quality determinant to protect your room! You will be able to maintain home coziness and comfort.

The climate of our country requires the almost constant use of heating devices, which significantly contribute to increased dryness of the air, and optimal humidity in the apartment becomes an unattainable dream.

Nevertheless, the microclimate of a home plays a vital role in ensuring the health of the people living in it. When the level of moisture content does not reach the required values, every person, be it an adult or a child, will certainly encounter a number of unpleasant phenomena.

Mold control

If the humidity in the house does not meet the norm (indicators are too high) for a long time, then mold may appear on the walls. The best way to combat mold is to regulate the microclimate. You need to ventilate the room twice a day for at least 5-15 minutes, do not dry things on the radiator, do not cover damp walls with carpets, do not put damp things in the closet, and do not close bathroom doors. An antiseptic primer, bleach, ammonia, hydrogen peroxide, vinegar and baking soda will help get rid of fungus on the walls.

A special antiseptic primer is sold in building materials stores. Bleach is not as effective, but is less toxic. Sodium hypochlorite (the active ingredient in most bleaches) helps get rid of most types of mold and spores, but can ruin some surfaces. In addition, the product emits toxic fumes and corrodes the skin of your hands, so you should only work with it wearing rubber gloves and with the windows open. A weak acid that will kill many common types of mold is table vinegar. For prevention, you can spray vinegar from a spray bottle onto problem areas every week.

Hydrogen peroxide is an antifungal and antibacterial agent, does not emit a pungent odor or harmful fumes

Peroxide bleaches, so this product must be used with extreme caution on some surfaces. Ammonia works well to remove mold on hard, non-porous surfaces, such as tiles or glass.

Baking soda is a natural and safe household cleaner that does not contain harsh chemicals. To prevent fungus, you can periodically wash surfaces and things with a sponge soaked in a soda solution.

How to measure air humidity in an apartment

The well-known humidity norm of 55–60% must be confirmed with special instruments.

In stores there is a device called a hygrometer, which allows you to accurately determine humidity levels. There are several types of these devices:

hair;
weight;
electrolytic;
condensation;
ceramic;
weight;
film

Among the rich variety, everyone can choose the equipment that will not hurt their pockets and will accurately determine the required indicators

When choosing humidity measuring instruments, you should pay attention to their technical characteristics. As a rule, the standard range of values is from twenty to ninety units

Before you begin observations, measure the apparatus error, which can vary from one to five scale values.

It is worth noting that if you intend to measure indicators in rooms with a high level of moisture in the air, it would be best to prefer a device that has a high degree of protection against its penetration and condensation.

Recommendations for choosing a hygrometer

Modern hygrometers differ not only in functionality, but also in size, price and measurement accuracy.

Standard humidity is considered to be between 40 and 60%. Humidifiers or dehumidifiers can be used to create optimal indoor conditions.

The most optimal type of devices are considered to be digital devices, for the use of which you do not need to make any calculations or have any professional skills.

Such a hygrometer should be selected based on the following criteria:

manufacturer's permissible measurement error;
width of the range of operating values;
heating threshold if the device is planned to be used in saunas or baths;
speed of calculation of results;
compactness and mobility;
the presence of additional options - clock, calendar, alarm clock, barometer, built-in Wi-fi module and others;
price category and manufacturer.

Before purchasing a hygrometer, you should carefully study not only the characteristics of devices offered on the market, but also reviews from customers who have already tested the device in action.

By purchasing a high-quality hygrometer, you can be confident in the accuracy of relative humidity measurements. However, a number of related questions arise about how to normalize the microclimate and what methods and devices to use to normalize indicators.

Device for determining air humidity

Thermohygrometer

is a very complex device that measures not only air humidity, but also room temperature. Among other things, the thermohygrometer records readings about the state of temperature and humidity recorded from different points. That is, directly from the place where the thermohygrometer itself is installed and from the point where the sensor was previously installed.

The device synchronizes readings received from different points in the room, and based on this, it already provides results for checking humidity levels and measuring temperature.

A few words can be said about the technical characteristics of the thermohygrometer. The cable of this device is one and a half meters long, and the indicators are displayed in the range from 0 to 90%. Wireless models also available

thermohygrometers. These devices are equipped with another useful function, which is that when the humidity in the room is critical, an alarm is triggered, notifying about an unfavorable change in the air condition.

Measuring device

Today there are several types of household devices for measuring air humidity in rooms or apartments. How is air humidity in rooms measured and determined? Let's take a closer look at all types of hygrometers.

Thermohygrometer

Air humidity can be measured using a thermohygrometer. Let's look at his work. It has a complex system, so it determines not only the moisture level, but also the temperature inside the room. Also, in addition, this device records the values of the moisture state and temperature values at various points. That is, he compares the state of two indicators in the place where he is at this moment and in the previous room.

A device for determining air humidity synchronizes the values it received at different points in the building. According to these readings, the thermo-hygrometer gives an overall result of the humidity and temperature values. What technical characteristics does it have?

Let's look at the technical characteristics of the thermohygrometer. The length of the wire is 150 centimeters. Indicators are displayed as percentages, the range of which is from 0 to 90. You can also purchase thermohygrometer models in stores that are wireless.

These models have an additional function: when the moisture level in the room is critical, the measuring device gives a signal that notifies the owner about the poor air condition. It is convenient to use this device(s) or meter when measuring humidity in an apartment.

With this hygrometer you can measure temperature and humidity. You will literally be involved in changing the “weather” at home.

Psychrometer

This room apparatus is called in full - a psychrometric hygrometer. How to determine the air humidity in an apartment using a psychrometer? They have two thermometers. One thermometer is called “dry”, which does the standard job of measuring room temperature.

The other thermometer is a wet thermometer because it is inside a water vessel and is wrapped with a cloth wick. It gives an indication of the temperature of the wick, which is wet. The value of this temperature is obtained due to the evaporation of moisture. If the humidity level is low, then evaporation occurs much faster. And vice versa.

Thanks to a psychrometer, you can get the necessary information about the state of your room, that is, determine the air humidity. Today, a psychrometer is often used to control moisture content.

Devices: hair and film

A hair device for measuring indoor air humidity is quite easy to construct. Why is it called that? This type of hygrometer works on the basis of synthetic hair, which is fat-free. How to find out the air humidity on it? How to measure air humidity in an apartment using a hair device?

Due to changes in the air condition, this synthetic low-fat hair also changes its length. It is stretched between the spring and the pointer end. Due to the oscillation of synthetic hair, the arrow moves along the plate with divisions (dial), which gives the general values of the moisture level in the room. Let's discuss the “insides” of the device.

This device for measuring air humidity has a wide range of values - from 0 to 100. Therefore, information about the state of the air flow will be the most accurate. Its main feature is the simplicity of its operation. They are easy to handle so you won't struggle with it while using it. This meter can be placed on the wall in the room - it is quite convenient. Measure and find out information about the condition of the apartment, which will always be before your eyes.

There is another type of hygrometer - a film one. How to check the air humidity in an apartment using it? The film hygrometer is constructed differently, and therefore the operating principle is different from the hair hygrometer. The main distinguishing feature of a film hygrometer is the presence of an element that is sensitive. This component in the device is an organic film. The principle of operation is that the organic film can stretch, or vice versa, shrink - this depends on the state of air humidity in the house. The humidity value is also displayed on the dial.

If there are relatively low temperatures in a certain humid room, then it is recommended to use hair or film hygrometers. Other devices are simply not suitable for determining the level of humidity in a room; they are practically not used.

Scope of application

Despite the fact that this material appeared on the market relatively recently, it is already widely used for interior and exterior work. Transparent and semi-matte water-based varnish are often used to cover parquet boards. There are specially developed compositions that make it possible to obtain a particularly durable and elastic coating that can withstand regular friction.

It should be taken into account that a special varnish, acrylic parquet, is suitable for covering only the specified flooring material. If it is used on solid plank floors, it will quickly lose its appearance.

Floor varnish of this type must include special additives to ensure its durability. In this case, the material must be applied in 2 and sometimes 3 layers to create a high-quality coating. Special acrylic urethane varnish has a fast drying speed. How long water-based acrylic varnish takes to dry depends on the temperature in the room, but in most cases 1-2 hours are enough for it to harden. This allows you to speed up the coating creation process.

A special composition has also been developed for indoor walls. It can even be used effectively to decorate walls in bathrooms and kitchens, because... It is distinguished by its ability to withstand high humidity and temperature changes. It is often used to treat the surfaces of railings, steps and windows located in the house.

Acrylic clear varnish can be used to process products made from wicker, figurines and homemade furniture. A special varnish for paintings has also been developed. It is suitable for paper of any thickness and coating of canvases. It can be used to process frames. There is a composition on sale that is suitable for decoupage. Water-based glossy acrylic varnish is often used in the restoration of antique wooden furniture.

Polyurethane varnish, which is resistant to various weather conditions and ultraviolet radiation, is often used to cover open wooden verandas, gazebos, and external walls. In addition, it is well suited for treating interior walls and floors in baths and saunas, because... has high water-repellent properties and the ability to withstand temperature changes. It is often used for exterior treatment of house walls. It can be applied to decorative plaster, increasing the service life of this finish.

How to increase air humidity

Knowing how to check the air humidity in an apartment, you will see, albeit not an exact, but an approximate picture of the real situation. Thanks to this, you can take the following measures to saturate it with moisture.

Humidifier

As a rule, such devices are designed to operate in rooms up to 150 square meters. The principle of its operation is as follows: water is poured into a special tank to a certain level. When a humidifier operates, water evaporates and saturates the air with its molecules.

There are three types of humidifiers.

Traditional type

The mechanical humidifier accomplishes its mission with the help of a built-in fan. It forces air through a special container with water, as a result of which the air is cleaned of dust and saturated with moisture.

Steam type

Such a device works in the same way as a kettle. The water boils and comes out as steam. Some models have special attachments for inhalation. Thus, the device can be used not only to increase air humidity, but also to treat the respiratory tract.

Flaws:

Hot steam, the temperature of which reaches 60 degrees, can cause, if safety rules are not followed, damage to human skin and the surface of nearby objects.
High noise level during operation.
Quite a lot of electricity consumption.

Ultrasonic type

Such a device, thanks to a built-in special membrane, turns water into steam. It is less noisy than mechanical and steam humidifiers. The presence of a water heating function contributes to the effective fight against microbes in the air.

Works only with distilled water or with special cleaning cartridges to clean and soften the liquid. The latter should be changed regularly.

Traditional methods of increasing humidity

If you don’t have a humidifier, you can use simple folk methods not only to determine the air humidity in the room at home, but also to correct the situation.

In this case, the following measures are suitable:

The easiest way is to place a wet towel or sheet on the radiator. When the fabric is heated, the water from it will begin to evaporate. After the towel has dried, it should be wetted again.
An analogue of the first method is to place containers of water on heating devices. You will need to add water inside the container every few days.
You can place containers of water on pieces of furniture, such as a cabinet. With this method, the water does not evaporate as quickly as with a battery, but still, the humidity increases.

For the next method you will need a bowl of water and a bandage. Having placed a cup of water near the radiator, one end of the bandage should be placed in the water, and the other should be secured to the heating element. The water will constantly rise up the threads of the bandage and, with the help of the heat emanating from the battery, evaporate into the air.
If the air is too dry, drying washed clothes indoors can moisten them.
The presence of a large number of indoor plants has a beneficial effect on normalizing air humidity levels.
After showering, leave the bathroom door open. This way you will get rid of excess moisture in the bathroom and saturate the air in other rooms with it.

What signs in an apartment indicate high or low humidity?

Various little things will help determine the humidity in an apartment.

You just need to pay attention

p, blockquote 25,0,0,0,0 —>

Condensation on the windows will be the first to indicate increased water content in the air. Everything in the house will become damp, and the furniture will begin to smell like wood. Then the sense of smell will begin to distinguish notes of rotting and decomposition, and a specific musty smell will appear.

Under such conditions, mold and mildew will quickly begin to develop, infecting household members with various diseases.

If children have diathesis, this may be the reason for the high moisture content in the air. Attacks of asthma, cough and headache can confirm this. If you don't take action, you can get more serious illnesses. Such as otitis media, bronchitis and decreased immune defense.

Cancer cells multiply faster in high humidity.

The state of the human body changes even with a lack of moisture. People get tired faster, become drowsy, and sweat excessively. This leads to drying out of all the mucous membranes of the body, which can have serious consequences.

p, blockquote 28,0,0,0,0 —>

If dust hanging in the air is clearly visible in the room, then the humidity level has dropped significantly. The air is dry and particles (under the weight of water) do not settle on objects, but are easily drawn into the lungs. Exacerbation of allergic reactions confirms this.

The importance of humidity in human life has been undeniably proven. Therefore, it would be wise to constantly monitor its norm

To do this, you can use both purchased measuring instruments and use the experience of your ancestors. Paying attention to everyday details will help you understand that deviations have occurred. This will allow you to quickly correct the situation and bring everything back to normal.

The well-being and health of its owners depends on the state of the microclimate in the apartment. The level of humidity is one of the main indicators characterizing the parameters of the air that people in the room breathe. Therefore, it must be periodically monitored. This indicator must remain at the level established by sanitary and hygienic standards.

Therefore, the residents of the house are faced with the question of how to determine the air humidity in the apartment. Various methods are used for this. Even without special instruments, anyone can measure the humidity level in a room. Existing methods will be discussed in detail below.

How to maintain relative humidity in your home

We have already decided how to measure the humidity level in the room; now we just need to figure out how to restore the optimal humidity level.

If the humidity is low

Ventilate the room.

However, this method cannot always significantly improve the state of the home microclimate, since in the summer the street air can be dry.

Also, when ventilating in the traditional way, dangerous microbes, allergens, dust, harmful gases and unpleasant odors can enter the apartment. But if you keep the windows constantly closed, then there is a high probability of encountering another problem in maintaining the microclimate - stuffiness (high levels of carbon dioxide).

High-quality ventilation is also important when ventilating rooms. A valve can provide fresh air into the room, but it will not be enough to ventilate a room inhabited by more than one person. The air passing through the supply and exhaust valve is not heated and not cleaned.

A breather will help you easily deal with the stuffiness and not let dangerous “guests” from the street into your house. This is a supply ventilation device that takes air from the street, heats it, cleans it and supplies it to the room.

Do wet cleaning regularly

rooms.

Install an aquarium at home.

Keeping fish in an aquarium at home can also affect air humidity.
But remember that you need to take care of the fish and keep the aquarium clean. water containers
on window sills or near heating radiators .

Humidifier

- a good option for home. This device will cope with dry home air, improve the microclimate and prevent the development of respiratory diseases.

Climate control equipment (air conditioner, breather, air purifier, Danfoss Eco thermostat)

Complete with the MagicAir base station, it will help not only track the data on the microclimate in the house, but also maintain optimal indicators.

The base station collects information from room air about temperature, humidity and carbon dioxide concentration. All indicators are displayed on the smartphone screen in the MagicAir application.

If the humidity is high

The other side of the coin is that there is too much moisture in the air.

Do not dry clothes in the apartment.
It is best to do this on the balcony.
After taking water procedures, when the air humidity in the bathroom can reach 100%, you need to ventilate
. With good ventilation, it will be enough to open the door to the bathroom and the window closest to the bathroom or turn on the breather.
You can purchase a special device for absorbing moisture
. The operating principle of this device is the opposite of the air humidification process: a built-in fan drives moist air through the device. There is also an evaporator inside, which turns moisture into condensate, which flows into a special container.

If you get into the habit of constantly maintaining optimal air humidity at the required level, this will help reduce the risk of developing respiratory diseases and cases of allergic reactions. Normalized humidity has a beneficial effect on the skin, protecting it from drying out and premature aging.

Optimal air humidity in an apartment for a child

The level of humidity in the apartment in which the child lives is a very significant indicator. The health of the baby and the peace of his relatives depend on it.

The fact is that the child’s body undergoes a thermoregulation procedure in a special way, so dry air can negatively affect it. The air that a baby exhales has one hundred percent humidity and body temperature. If the humidity of the surrounding space is low, the child will have to spend a lot of internal fluid to humidify the air. Loss of water from a child’s body can lead to unpleasant consequences that are best avoided. The more humidified the air, the less money we will spend on medicines. This is a rule that should be taken as a basis.

To maintain this level, you can use any of the following methods:

regular wet cleaning;
presence of an aquarium;
wet towels on radiators or bowls of water in the room;
modern humidifiers.

Maintaining the necessary humidity in a children's room is not at all a difficult task, and the presence of undeniable advantages makes every parent strive to achieve it.

Principle of operation

To solve the question of how to make single-pipe heating in a private house, it is necessary to study the principle of its operation. The main element of a single-pipe scheme is a gas or solid fuel boiler. With its help, water is heated, which subsequently goes into the pipes and radiators of the heating system. During the movement, the coolant gradually cools down and returns to the boiler through the return pipe.

The peculiarity of such a system is that the first and second radiators will heat up more, and in the last radiators the water temperature decreases significantly, therefore, it will be colder in this room

In this case, it is important to understand how to properly make a one-pipe heating system.

You can solve the problem as follows:

Increase the heat capacity of radiators located far from the boiler, which helps to increase heat transfer.
Increase the temperature of the water leaving the boiler.

However, both options require significant material costs, which makes the entire heating system expensive.
