Standards for water temperature in batteries, air parameters

As a rule, increasing tariffs for residential heating leads to people's dissatisfaction with the quality of heat. This can be called simply a negative reaction to increased bill amounts, but it may well be that the temperature of the water in the heating radiators is very far from normal. In this situation, consumers should be aware of their rights and responsibilities, and that they can request a refund from the service provider.

You should always check the water temperature level in the radiators

Fight for warmth

It is better to think about possible heat loss in your home in the summer. But if this has not been done, then it is possible to insulate the house with the onset of winter. The first thing to do is to identify weak points where heat loss is possible.

Windows according to standards

The main source of cold is windows. Nowadays there are double-glazed windows above heating radiators and radiators almost everywhere. But even plastic window frames age. The sealing rubber becomes unusable.

Central heating in the apartment

The windows begin to let in the cold. The easiest way is to stretch plastic film over the frames. It is sold in stores in rolls. This material does not have any effect on the transparency of the glass. Heat loss in radiators or radiators will be reduced.

The film is fixed to the glass. Before this, the frames are thoroughly washed. Double-sided tape is applied around the perimeter. A film is attached to it. It's easier to do this together.

Battery on the wall

If wrinkles have formed on the coating, heat the film with a hairdryer until they straighten out. Then all that remains is to seal the frames. They do this with single-sided tape. Such a simple method helps to retain up to 20% of heat.

Every morning you should open the curtains and raise the blinds. The apartment is perfectly warmed by sunlight penetrating into the room through the glass. Double glass frames create a magnifying effect, enhancing the warmth of sunlight. When it gets dark, the windows should be closed. At night, glass draws heat out of the room.

Radiator under the central window

Batteries according to standards

The batteries are located along the walls. Dank damp partitions take away heat. A simple reflector will help avoid this. A reflector is not a technical device. This is simply a sheet of foil attached to a radiator or radiator.

The reflector sheet is made slightly larger than the area occupied by the radiator or radiator. A homemade reflector will raise the room temperature by at least 2 degrees.

Porilex and penofol have lower thermal conductivity than foil. This is facilitated by the insulation layer they have.

Heating batteries

It is necessary to require compliance with water standards in heating devices from utility services. But the comfort in the house cannot be left only to the mercy of the management company. It is always safer to take care of the microclimate in your home yourself.

Temperature of heating radiators in the apartment standards

Apartment heating standards determine the specific value of a sufficient indicator for residential and non-residential premises, with permissible deviations from their indicators.

They are developed more simply than for work premises, since those living in the housing exhibit low and, at the same time, stable activity:

• For residential premises, the air temperature is from 20 to 22 degrees Celsius, while acceptable limits are considered to be from 18 to 24 degrees;
• If we take corner rooms, then the indicator should not be less than twenty degrees, since such rooms are more susceptible than others to low external temperatures and winds;

Interruptions in the heating system

There are cases when the movement of water through the system stops and cools down, without creating a heat flow and without heating the apartment. According to regulatory documents, the management organization has the right to make a temporary suspension. However, she must adhere to the following rules:

1. Within one month, the total break time should not exceed 24 hours.
2. The duration of the break cannot be more than 16 hours when the temperature in the apartment is 12-22 °C.
3. The duration of the break should be less than 8 hours if the air in the apartment is heated to 10-12 degrees.
4. A break of 4 hours if the air temperature is 8-10 degrees.

Air ratio parameters

The room must have a certain air exchange rate, for example, if the room is residential and has an area of ​​18 or 20 m2, then the rate should be 3 m3/h per square meter. m., the same parameters are also necessary in regions where the temperature reaches −31°C and drops below. In dormitory kitchens and apartments equipped with electric and gas two-burner stoves and having an area of ​​up to 18 m2, aeration is 60 m3/h. If there is a three-burner appliance in the room, then this value will be 75 m3/h, if there is a gas stove with four burners - 90 m3/h. For a bathroom with an area of ​​25 m2, the air exchange rate should be 25 m3/h, and for an individual restroom with an area of ​​18 m2 - 25 m3/h. If the bathtub and toilet are combined and their area is 25 m2, then the aeration is 50 m3/h. If the common restroom has an area of ​​16 m2, then an air exchange rate of up to 50 m3/h is required for one toilet, and 25 m3/h for a urinal. If the room is corner, then the room should be 2°C higher than usual. During warm periods, the temperature in the elevator room should not exceed 40°C.

Requirements for heating networks

With centralized heat supply, the heat source is a boiler house or a thermal power plant, where high-temperature water-heating boilers are installed (in thermal power plants - steam boilers). The fuel is usually natural gas, with other energy sources being used to a lesser extent. The temperature of the coolant at the outlet of the hot water boiler is 115 °C, but the water does not boil when it is under pressure. The need to heat up to 115 °C is explained by the fact that boiler plants operate at maximum efficiency in this mode. The transition from 115 °C to the required temperature value is provided by plate or shell-and-tube heat exchangers. At a thermal power plant, waste steam from turbines enters heat exchangers to produce electricity. According to regulatory requirements, the water temperature in heating pipes should not exceed 105 ° C, the lower limit depends on street conditions. In this range, the heating of water in the heating network is regulated depending on the weather, for which each boiler room has a temperature graph of the heating system. For home networks, 2 calculation schedules are used: 105/70 °C; 95/70 °C.

These figures show the maximum temperature of the supply and return water during the most severe frosts in a particular area. But at the beginning and end of the heating season, when the weather is not yet too cold, there is no point in heating the coolant to 105 °C, so a real temperature heating schedule is drawn up, which describes to what extent the water should be heated at different outside temperatures. The dependence of heating on weather conditions is shown in the table, which presents excerpts from the graph for the city of Ufa: Average daily street air temperature, °C at the supply with a design schedule of 105/70 at the supply with a design schedule of 95/70 in the return +8 43 41 36 56 52 43 -5 64 59 48 -10 71 65 52 -15 78 72 56 -20 85 78 59 -25 92 84 63 -30 99 89 67 -35 105 95 70

The table is presented as an example and is correct only for this city; another locality has its own dependence, because the climatic conditions in the country are different. It is quite difficult to find out exactly what the coolant temperature is in a centralized heating network. To do this, you need to have a remote thermometer that determines the degree of surface heating. So, it is possible to determine to what extent the heating standards in the apartment are met only by the air temperature in the rooms.

Dependence of coolant temperature on weather

A schedule is drawn up in the heating network according to a simple principle - the lower the temperature outside, the higher it should be for the coolant.

This ratio is an important basis for the operation of enterprises that provide the city with heat.

For the calculation, an indicator was used, which is based on the average daily temperature of the five coldest days of the year.

ATTENTION! Maintaining the temperature regime is important not only for maintaining heat in an apartment building. It also allows you to make energy consumption in the heating system economical and rational.

A schedule that indicates the temperature of the coolant depending on the outside temperature allows you to distribute not only heat, but also hot water among the consumers of an apartment building in the most optimal way.

Temperature measurement techniques

An ordinary household thermometer on the surface of a heating device. A device designed to measure temperature in a non-contact manner. Such a meter is called -

. Alcohol thermometer. A special electrical device. If you take measurements with an ordinary thermometer, you will need to add a few more degrees to the indicators. The most accurate readings can be obtained using an infrared device - a pyrometer. Its error is no more than 0.5 degrees. To regularly monitor temperature, use only the safest device - an alcohol thermometer. For these purposes, it is attached to the radiator using tape and wrapped in thermal insulation material. How to use the electric version of the thermometer? You need to take a wire with a thermocouple and attach it to the heating device. This is how the indicators are taken. If a commission comes to your apartment to measure the temperature of the batteries, they must have a certified device. You have the right to demand from a representative of the inspecting organization documents confirming that the equipment has passed state verification. Very serious requirements are imposed on the heating system. The process of delivering hot coolant using circulation pumps (the installation rules for the heating system are written here) to a residential building and its uniform distribution throughout all apartments is not an easy task. This issue must be approached responsibly, and with an understanding of all the technological subtleties. In order for the heating system to work efficiently, all its elements must function harmoniously. This applies to all pipes and radiators in each of the apartments of a multi-story building. Therefore, when replacing radiators (read how to install heating radiators in a private house in this article), you need to take into account the features and subtleties of the heating main. If this is not done, some apartments will experience an excess of heat, while bad times will come for the residents of other apartments (they will have cold radiators). How can the heating of urban dwellings be optimized? Answer: by introducing the following standards: the safety regulations state that the temperature of the working liquid substance in the heating main must be 20 degrees less than the temperature of self-igniting materials. For residential multi-apartment buildings, the coolant limit has established standards - 65 - 115 degrees Celsius (this takes into account seasonality); if the water, for some reason, overheats and reaches a reading of 105 degrees, emergency measures must be taken to prevent it from boiling; the standard limit for water circulating through the batteries is 75 degrees. In case this indicator is exceeded by the battery needs to install a restrictive structure (about methods of heating in a private house is written here); in regions located in the middle latitudes of our country, the heating season, as a rule, begins on the fifteenth of October and ends on the fifteenth of April. In some cases, these standards may be changed. Service providers should rely on the average daily outdoor temperature.

The apartment is cold, why complain?

Before you go looking for heat, you should remember that heat in the room will be supplied through the heating system only when the outside temperature reaches a certain level.

Standards require heating to start when the outside temperature is no more than 8 degrees. This temperature indicator must last for five days in a row, and only after this the rooms will begin to be heated.

When the heating in the house is adjusted, and temperature deviations are observed only in your room, it is necessary to check the indoor heating system for airing.

It is enough to feel the individual batteries in the apartment from top to bottom, and back. If some of the batteries are noticeably warm and the rest are cold, you can be sure that airing is the cause of the thermal imbalance. The air is released using a separate tap, which is located on each radiator battery.

Before opening the tap, you should place some container under it. When you open the tap, water should come out of it with a characteristic hissing sound. If the water begins to flow smoothly and without hissing, it means that the air has been released from the system, and the job is done.

After this, you should fix the tap in the closed position. After a while, check the cold spots on the battery, they should warm up.

If the problem is not with the batteries and they are completely cold, you should contact the management company. The technician will arrive within 24 hours. He will be able to draw a conclusion about the temperature conditions in the home and, if necessary, call a team that will fix all the problems.

When the management company did not respond to your appeal or the appearance of a technician did not change the situation, you should take temperature measurements in your home yourself, calling your neighbors.

When you have a device such as a pyrometer at your disposal, you should use it to take the necessary temperature measurements. Record all data in a report on measuring the air temperature in your home. It is compiled in the usual form. Let the neighbors sign the act.

You should pay attention to the fact that the temperature regime is determined by the “Sanitary and Epidemiological Requirements for Residential Buildings and Premises” SanPiN 2.1.2.1002-00. Recorded measurements should be compared with the limit values ​​specified in SanPiN

Then you need to go back to the management company and the organization that supplies the house with heat to write a written complaint

Recorded measurements should be compared with the limit values ​​specified in SanPiN. Then you need to go back to the management company and the organization that supplies the house with heat to write a written complaint.

The document is drawn up in two copies. One of the copies must be in your hands with a stamp, signed indicating the details of the person who accepted the document and the date of receipt of the document. The second one must be submitted for consideration.

If you were not satisfied with the answer, then there is no need to leave everything halfway, move on. You should contact the district Prosecutor's Office and the Housing Inspectorate, since it is she who is authorized to monitor the work of the management company and other communal structures.

Also write a letter to Rospotrebnadzor (based on the violation of your consumer rights). You can use the Rospotrebnadzor hotline (8-80-010-000-04).

Strict recording of temperature standards for heating radiators in an apartment is important

Knowing the room temperature standards will help you detect a malfunction and contact the appropriate authority for a solution.

Temperature indicators are regulated by GOST and SNiP standards.

ontakte

Odnoklassniki

The main indicator is indicated in document number 51617-2000. In accordance with it, the temperature should be:

• on a flight of stairs - 14-20 degrees;
• in the lobby and corridors - 16-22;
• in hallways, living rooms and other rooms of the apartment - 18-25;
• in the bathroom - about 24.

The temperature is more precisely regulated by GOST 30494-2011:

Minimum indicators

Heating rooms is important at any time of the year, but especially in winter.

The heating system has typical temperature values ​​that must be observed.

For each room there is a small interval presented in the table above. There is no minimum threshold as such.

But there are several indicators, a drop below which indicates a malfunction. This applies to heating premises: the law allows the temperature to drop to 12, 8 and even 4 degrees, but only for a short period of time - 16, 8 and 4 hours, respectively.

Maximum water temperature in radiators

SNiP 41-01-2003 establishes temperature limits from above: for piping from one pipe, heating of the coolant is allowed to 115 degrees, from two - up to 95°C. Despite the permitted values, they rarely exceed 80-85°C.

Attention! These rules apply to indoor parts of the heating system

Parameters by which central heating in the house is turned on

The Decree of the Government of the Russian Federation characterizes the need to turn on the heating at an average street temperature of +8°C or less. When heating, the temperature is measured at +5°C or more. Both values ​​must last for at least 5 days in a row.

How to adjust and increase heat transfer

To change the temperature of heating radiators, it is necessary to install special regulators on them. There are 4 types of such devices: regulators with a locking mechanism, manually controlled valves, thermostats with automatic settings, radiator thermostats.

Photo 2. Manual thermostat for a radiator. By turning the knob you can set the desired temperature.

In order to increase the temperature of the radiator, it is necessary to open the regulator and let more coolant into the heating device. And, conversely, to lower the temperature, it is necessary to drain excess coolant.

What to do if there is no heating and a radiator malfunction

After detecting a problem, it is necessary to draw up a report indicating the unacceptably low temperature in the room. They contact the organization that supplies heat. The statement indicates the period during which the problem has been observed and the actual thermometer values. Based on the information, an inspection is carried out, compensation is calculated and a decision is made.

By law, during the heating season there can be a break of no more than 24 hours per month. The following conditions correspond to this: the temperature cannot fall below 12 degrees, and the shutdown should not last 16 hours in a row.

Important! There are two exceptions: the room can be 8-12 degrees for up to 8 hours in a row, or from 4 to 8, but no more than 4. Watch the video, which talks about what heating standards should be in an apartment

The impact of temperature on the characteristics of the coolant

In addition to the factors listed above, the temperature of the water in the heating pipes affects its characteristics. The method of functioning of gravity heating systems is based on this. As the water heating value increases, it expands and circulation appears.

Coolants for heating systems

But when using antifreeze, exceeding normal temperatures in radiators can lead to different results. Therefore, for heating with a coolant other than water, it is necessary to first determine the permissible heating values. This does not apply to the temperature of the central heating radiators in the apartment, since such devices do not use antifreeze-based liquids.

Antifreeze is used if there is a risk of exposure to low temperatures on radiators. Unlike water, it does not change from liquid to crystalline at 0 degrees. But if the heat supply operation exceeds the norms of the temperature table for heating to a greater extent, the following phenomena may be observed:

1. foaming This contributes to an increase in coolant volume and pressure level. There will be no reverse process when the antifreeze cools;
2. the appearance of limescale. Antifreeze contains mineral components. If the heating temperature in the apartment is violated, they precipitate. Over time, this leads to clogged pipes and radiators;
3. increase in density. Malfunctions of the circulation pump may occur if its rated power was not designed to handle such situations.

We recommend: What types of regulators are there for central heating radiators?

Therefore, it is much easier to monitor the water temperature in the heating system of a private home than to control the heating level of antifreeze. Moreover, substances based on ethylene glycol emit gases that are harmful to humans when evaporated.

Today they are almost never used as a coolant in autonomous heating systems. Before using antifreeze in heating, it is necessary to replace all rubber seals with paranitic ones. This is due to the high level of permeability of this type of coolant.

Options for normalizing heating temperature

Minimum water temperatures in the heating system are not considered the main threat to its operation. This affects the microclimate in living rooms, but does not affect the operation of the heating supply. If the water heating norm is exceeded, emergency situations may occur.

Safety group for autonomous heating

When creating a heating scheme, you need to provide a list of measures aimed at preventing a critical increase in water temperature. First of all, this will lead to increased pressure and stress on the inside of pipes and radiators. If this happened once and lasted a short time, then the heating parts will not be damaged.

But such cases appear under the constant influence of specific factors. Most often this is the incorrect operation of a solid fuel boiler. To avoid breakdowns, it is necessary to upgrade the heating in the following way:

• installation of a security group. It consists of an air vent, a bleed valve and a pressure gauge. If the water temperature reaches a critical level, these parts will eliminate excess coolant, thereby ensuring normal circulation of the liquid for its natural cooling;
• mixing unit. It connects the return and supply pipes. Additionally, a two-way valve with a servo drive is mounted. The latter is connected to the temperature sensor. If the heating level exceeds the norm, the valve will open and a mixing of hot and cooled water flows will occur;
• electronic heating control unit. It distributes the water temperature in different parts of the system. If the thermal regime is violated, it sends a corresponding signal to the boiler processor to reduce power.

These measures will prevent improper heating operation at the initial stage of the problem. It is most difficult to control the water temperature in systems with a solid fuel boiler. Therefore, for them, special attention must be paid to the selection of indicators of the safety group and the mixing unit.

Methods for measuring water in radiators

When considering the question of how to measure the temperature of a battery in an apartment, the following methods can be distinguished:

• an ordinary thermometer (on the surface of the radiator);
• infrared thermometer;
• alcohol thermometer;
• special electrical device.

When measuring with a regular thermometer, you need to add 1-2 degrees to the result. A more accurate result will be given by an infrared device, the error of which is 0.5 degrees.

In order to regularly monitor the temperature of the water in the batteries, you can use an alcohol thermometer. To do this, the device is attached with tape to the radiator and wrapped in heat-insulating material.

The battery may not heat up evenly.

You can also use an electric version of the thermometer for measurements. To do this, a wire with a thermocouple is wound to the battery, and it takes readings of the degree of heating. If a consumer calls a special commission to measure the temperature of heating radiators in an apartment, then their device must have a quality certificate and first pass state inspection. The actions of specialists must comply with GOST 30494-96 (clause 4 in the “Control methods” section).

If the temperature of the heating pipes in the apartment is higher than normal, then it can be adjusted in several ways:

• using special devices;
• ventilation;
• using thick curtains.

There are special taps with which you can regulate the temperature. They are installed on each radiator. A simpler method is to ventilate the room. You can also simply use curtains made of dense material, which will let less sunlight into the room. It is much easier to deal with high room temperatures than low ones. What to do if the minimum temperature of the batteries in the apartment is lower than indicated in the temperature chart? To do this you should:

• call utility services;
• insulate windows, doors and walls;
• install new radiators.

If you don’t know how to check the temperature of the batteries in the apartment, you can call specialists. Also read: “Blowing and cleaning batteries.”

Utility services measure plumbing and heating systems. After this, an act is drawn up. Then, if the tenant's claims are confirmed, utility companies must increase or decrease water heating. Another way would be to install new heating radiators. Details about the installation can be found in the video:

You should pay attention to the material from which the batteries are made. Aluminum radiators have high thermal conductivity, so they will transfer heat well

But cast iron, although they are able to retain heat longer, will release it more slowly. Because of this, the room will take a long time to warm up.

Aluminum radiators have high thermal conductivity, so they will transfer heat well. But cast iron, although they are able to retain heat longer, will release it more slowly. Because of this, the room will take a long time to warm up.

The speed of water movement also affects the temperature in the heating pipes in apartments. Don’t forget that corner apartments are always cooler, because they have more walls in contact with the street. To reduce heat loss, it is necessary to insulate the walls. Insulating windows and doors through which cold air enters will also not be superfluous.

You can read more about infrared heating and energy consumption in this article.

Adjusting heating at home

If, after you have measured the heating of radiators at home with your own hands, the heating of the pipes exceeds the norm, then it should be adjusted. This can be done using special devices by hanging curtains with increased density on the windows.

But what to do if the heat is not enough? In this case, you should call the utility workers. Specialists must take measurements of data in the water supply and heating systems. Then they must draw up a final act. If non-compliance with the standard is confirmed, utility employees will resolve the problem.

If this option of calling utility services seems absurd or impossible to you, then the solution will be to insulate your home, and possibly replace the batteries with new heating devices.

When purchasing a radiator, first of all, you should pay attention to the material used to make the product. Aluminum models have the characteristics of increased thermal conductivity; therefore, they should heat the air in the room well. As for cast iron batteries, they retain heat much longer, but release it rather slowly. That is, the room will heat up for a longer time.

Heat loss can be reduced by insulating walls, window and door openings. Additionally, infrared heating can be installed. However, such systems consume the same amount of energy as other electric heaters with identical power ratings.

If you are unable or do not know how to determine the temperature of a heating device by hand or using other devices, you should immediately file a complaint with the housing maintenance office. In a situation where heating units are filled with air, a statement must be written to the Directorate for Building Operations. These services should send a specialist to you to solve the problem within 7 days.

Norm for an apartment

What temperature should the heating radiators of an apartment building be? It is useful to know that each room has its own heating standard in an apartment building (2017). Heating standards in apartment buildings 2021: for a living room it is +18; Heating standards in corner apartments due to the presence of external cold walls are higher - +20 degrees; for the kitchen +18; bathroom - +25. This applies to apartments, while for common areas the indicators are as follows: in the entrance - +16; for an elevator it is +5 degrees; in the basement and attic - +4. All measurements in the apartment must be carried out along the internal wall of the room at least 1 m from the nearest external wall and 1.5 m from the floor. If the obtained parameters do not comply with the standards, then they should be presented to the heating network management. In this case, payment may be reduced by 0.15% for each hour of deviation.

Heat supply requirements

According to the above-mentioned Resolution, central heating is launched after 5 days, during which the average outside air temperature does not exceed +8 °C. If after 4 cold days it becomes warm again on the fifth, the start of the heating period is delayed until the specified conditions are met. Heating standards stipulate that stopping heating occurs according to the same principle: 5 days must pass with an average daily temperature of +8 °C.

The Decree contains changes that provide for an individual approach to the supply of heat to buildings that fully comply with the requirements for thermal insulation. Heating supply organizations are required to turn on the heating of such houses as soon as the outside temperature drops to the value specified in the design documentation. It is not difficult to guess that in reality these changes are not being carried out very well, and the start of heat supply occurs simultaneously in all residential buildings - insulated and ordinary. During the heating season, the centralized heating system must provide multi-apartment residential buildings with a sufficient amount of thermal energy. In order for the heat supply service to be considered fully provided, the following requirements for permissible air temperature in premises for various purposes must be met: living rooms - from 18 to 24 °C, corner rooms - from 20 °C; bathroom (or separate toilet and bathroom) - from 18 to 26 °C; kitchen (taking into account the heat source in the form of a stove) - from 18 to 26 ° C; pantry - from 12 to 22 °C; corridor - from 16 to 20 °C.

For apartment buildings located in cold northern regions, the lower limit of permissible temperature in living rooms is increased to +20 °C (in corner rooms up to +22 °C). The increase comes into force provided that the frost outside reaches -31 °C (on average per day) and lasts for at least 5 days. It is also allowed to decrease the temperature in the apartment by 3 °C from midnight to 5.00 am. The heat supply to a number of apartments or the building as a whole may be interrupted as a result of an emergency and unforeseen repairs. But regulatory documents allot a certain time for carrying out repair work, depending on weather conditions. The colder the outside air, the sooner the relevant service must repair the fault. The total duration of interruptions in heating operation is no more than 24 hours per month.

What temperature of heating water should be at the entrance to an apartment building

But if the examination concludes that the standards have not been violated, its cost will be included in the payment for thermal energy. Practice shows that employees of a heating network company may not come with an inspection or their visit does not bring results. In such a situation, the act is drawn up independently and endorsed by at least 2 service users, and then by the chairman chosen by the council of owners of the apartment building. A copy of the act is officially transferred to the heat supply organization and is registered there.

The pipes enter the basement of the building. The supply of coolant is regulated by inlet valves, after which the water enters the mud traps, and from there it is distributed through the risers, and from them it is supplied to the radiators and radiators that heat the home. The number of valves correlates with the number of risers. When performing repair work in a single apartment, it is possible to turn off one vertical line, rather than the entire house.

What you should know about the temperature in heating radiators in an apartment

You can screw a thermal head into the end of the battery.

To live comfortably in an apartment, you need to monitor the temperature of the batteries. To do this you need:

• independently measure the temperature of the pipes (use regular, infrared, alcohol thermometers or a special electrical device with a thermocouple);
• call utility workers if the temperature does not meet the standards (as a rule, it is lower than required);
• if the temperature of the battery during the heating period in the apartment is higher than normal, then special taps can be used to regulate it.

A pleasant microclimate in an apartment is the key to health, so do not neglect it. In addition, the degree of air humidity plays a crucial role. If it is too dry, respiratory problems may result. The amount of fresh air is also standardized for each room separately. According to many experts, the standards are somewhat too high, so even if the air exchange is only half, this is quite acceptable.

When the housing office carries out work on connecting batteries

In Russia, the heating season begins when the average daily outside air temperature becomes below +8°C, and ends when it begins to exceed +8°C, and it must be maintained for up to five days.

Standards

Let's consider the minimum temperature in the rooms: In the living room +18°C; In the corner room +20°C; In the kitchen +18°C; In the bathroom +25°C; In the lobby and on the landing +16°C; In the elevator room +5°C; In the basement +4°C; In the attic +4°C. This value is measured on the inner wall of each room, and the distance from the outer wall should be 1 m, and from the floor 1.5 m. If hourly deviations from the standard parameters are noticed, then the heating fee should be reduced by 0.15%. Please note that this temperature standard is valid after the opening of the heating season, and there are no indicators for the off-season. You also need to know that hot water must have a temperature from +50°C to +70°C (SNiP 2.08.01.89 “Residential buildings”). It is measured by opening the tap and lowering the thermometer into the container to a special mark.

What should be the temperature of hot water at the entrance to an apartment building

In accordance with clause 5 of the “Rules for the provision of utility services to owners and users of premises in apartment buildings and residential buildings”, approved by Decree of the Government of the Russian Federation of May 6, 2011 No. 354, the beginning of the heating period should be set at an average daily outdoor temperature below 8 degrees Celsius. Celsius, and the end of the heating period - when the average daily outside air temperature is above 8 degrees Celsius for 5 days in a row. The specified period must begin or end on the day following the last day of such period. The heating season, in accordance with the Government Decree, begins by decision of local authorities. In Ryazan, the heating season started at the end of September, but many residents complain that it is cold in the apartment.

The document also specifies other standards that ensure a person’s quality of life. The water should be clear, without taste or smell. There is a fee for services, so if something is not up to standard, you need to complain. Where should you go if there is poor quality water? Consumers need to do the following:

What is the temperature in the batteries

There are certain parameters on this issue: Hot water should be supplied to the taps all year round, the temperature of which should be from +50°C to +70°C; During the heating season, heating devices are completely filled with this liquid. Let's look at how to measure the temperature of a radiator; to do this, open the tap and place a container with a thermometer. In this case, deviations are only possible upward by +4°C. If a problem arises in this matter, then you need to file a complaint with the Housing Office, but if the batteries are airy, then the application must be written to the DEZ. A specialist will come within a week and fix everything. Several more methods for measuring the temperature of heating radiators: Using a thermometer, measure the temperature of the heating pipes or the surface of the radiator. Add 1 - 2°C to the resulting value; In order to make these measurements extremely accurately, purchase an infrared thermometer-pyrometer, which determines the temperature with an accuracy of 0.5 ° C; Take an alcohol thermometer and apply it to the selected place on the radiator, glue it with tape and wrap it with any heat-insulating material (foam rubber, flywheel)

This is a permanent device for measuring the temperature of the heating system; If you have an electrical measuring device at home with the “measure temperature” function, then a wire with a thermocouple is wound to the battery and the temperature of the coolant is measured. This is important! If the temperature of the heating radiators does not satisfy you, then a commission will come to you based on a complaint, which must measure the temperature of the circulating fluid in the heating system. Their actions must comply with paragraph 4, which is specified in the “Control Methods” of GOST 30494−96, and the measuring device must be registered, state tested and have a quality certificate

Its range should vary from +5 to +40°C, and an error of 0.1°C is also acceptable.

Battery temperature

There are minimum and maximum standards. Sometimes, even when heating is started, there is not enough heat in the room due to the fact that the temperature of the radiators is far from the standards. The reason for this is the banal airiness of the system. You can fix the problems with the help of a specialist or yourself using a Mayevsky crane.

If the problem arises due to worn-out riser pipes or batteries, then you simply cannot do without the help of specialists. If the heating system did not work and the air in the apartment was colder than specified in GOST standards, then this entire period is not subject to payment.

To find out the temperature norm, you need to study SNiP

There are no minimum temperature standards for heating radiators, so it is customary to rely on the air parameters in the apartment. Normal air parameters during the heating period are +16…+25°C.

To document that the temperature of the heating system does not meet the norm, it is necessary to invite an authorized representative of the heating service provider. What the water temperature in the batteries should be is described in SNiP 41−01 of 2003:

1. If a two-pipe design is used in the room, then 95°C is the maximum.
2. The norm for a single-pipe design is +115°C.
3. The winter temperature norm for heating radiators in an apartment is +80…+90°C. If it approaches +100°C, then urgent measures must be taken to prevent water from boiling in the system.

Although many battery manufacturers often specify a maximum temperature threshold that is high, you should not reach it frequently as this will damage the battery.

To ensure that the heating complies with GOST standards, you need to take your own measurements and understand what the temperature of the water in the heating radiators is:

1. An ordinary mercury thermometer can be used, but then 2°C will need to be added to the result obtained.
2. An infrared thermometer will also work.
3. The alcohol thermometer must be tightly tied to the battery, wrapped in thermal insulation.

If the results obtained are far from normal, then you need to submit an application to the heating network office with a request to carry out control measurements . A commission will visit the apartment and make all the necessary calculations.
