Temperature hot water depends both on the type of water supply systems and on the time of day. At night, a temperature drop of 2 degrees lower than during the day is permissible.
Temperature standards
The standards for all indicators in the apartment must comply with SanPiN (sanitary rules and norms) and GOST. SanPiN prescriptions for hot water in 2017 have not changed. These norms were adopted for reasons of expediency, since too cold or hot water can harm human health. Citizens pay not only for the delivery of water, but also for the conveniences associated with a certain temperature.
The water temperature directly depends on the type of water supply. Simply - cold and hot water should be of their own, a certain temperature. The hot water temperature should be 60-75 degrees (not higher than 60 ° C and not lower than 75 degrees). This temperature is required for all draw-off points.
V closed system the water temperature should be 50 degrees (this is the minimum), in the open - 60 o C.
The following deviations are allowed by the rules for the provision of utilities:
- a decrease of 5 degrees at night (from 0 to 5.00 in the morning);
- lowering the temperature during the day by 3 о С (from 5.00 to 0.00).
Such rules are established for the sake of human safety. More hot water than according to the standard, you can get burned with varying degrees of severity. Elevated temperatures are especially dangerous for young children, who can turn on the tap, but do not immediately figure out how to dodge or block the flow of water.
But this is not the only reason why the temperature of hot water should not exceed 75 degrees. The fact is that the overwhelming majority of the water supply modern apartments consists of plastic. And, of course, the increased temperature negatively affects all plastic parts.
A temperature rise of up to 76% is considered a violation. Just as it goes down to 56 degrees during the day or up to 54% at night.
How to measure the temperature yourself
If it seemed to a citizen that the temperature of the hot water in the tap is much hotter than usual, then it should be measured according to all the rules. It is possible to present the requirements of the service organization only when measuring according to all the rules with a minimum permissible error. The thermometer must be in good working order and contain a 100 degree scale.
The algorithm of actions should be as follows:
- Open the hot water tap, while cold water should be closed. The water should be drained within 3 minutes. Stagnant water is usually slightly lower, so it should drain.
- Place a container under the stream of water, preferably with a volume of at least a liter.
- Without moving the container, take a measurement directly under the stream of water. It is desirable that the sensing element is located in the center of the water tank. In order for the experiment to be clean, you do not need to rearrange the container, let the water overflow.
- When the numbers on the thermometer are fixed, remember the result.
If the temperature does not correspond to SanPiN, then you need to complain to the housing and communal services. It is best to first call the control room to find out what caused the promotion. It may not be necessary to write a statement, since the temperature change can be explained by preventive work or repairs on the highway. In this case, the dispatcher must inform at what time the temperature is normalized.
If there is no good reason, then you should write a statement asking you to fix the problem. The application must be written in 2 copies, on one of which ask the secretary to put a mark. The second copy of the application is a guarantee that the secretary will refer your complaint for consideration.
In the video about checking the temperature of hot water
In the event of a routine inspection, the water supply can be suspended for no more than 4 hours. It is during this time that the temperature of the water in the tap may change. After a while, she will recover.
The 2019 standards that determine the temperature of hot water supplied to the room are established by a special document - the SanPin order. Just like last year, this indicator remained unchanged, which means that all Russians living in multi-storey buildings have the right to demand from the service organization full provision comfortable living in apartments, including hot water supply.
It should be noted that the problem is not even that the water has temperature regime not quite suitable for use. The problem is related to the danger posed by water supplies undergoing treatment contrary to accepted technology. Today we will tell you about what rules are in effect in Russia and what rights residents of an apartment building are endowed with.
Not every owner knows that the water temperature is determined by the water supply system. For each type of water supply device, the indicator is set its own, such as:
- for an open system - from 60 degrees Celsius;
- in a closed system - from 50 degrees Celsius.
According to the 2019 standards, the DHW temperature should not be higher than 75 degrees. The top level is no longer dependent on the type and configuration of the system.
This standard must be observed very strictly, and there are several well-founded reasons for this. In particular, we are talking about such important points:
- too low temperature indicator can cause the fluid in the pipes to become viscous, and pathogens begin to appear in it. When the temperature threshold is met, harmful bacteria die and do not reach the human body;
- Excessively hot water can cause severe burns to the user. Even at a temperature of 55 degrees, the risk of getting a burn is very high, therefore, to exclude such a situation in open system water supply is usually "mixed" with cold water;
- an excessive increase in the temperature of the hot water supply can lead to deformation of parts of the plumbing system made of plastic. This kind of danger began to increase, especially in last years, when people more and more often install plastic pipes in the apartment.
It will be very difficult to find the culprit here, since the hot water temperature was not initially measured. This means that compensation will not work either.
What deviations from the norms are allowed?
Sharp drop and rise DHW temperature can lead to serious disruptions and failures in the water supply system and even to possible injury to citizens. At the same time, there are a number of permitted deviations from established standards... These are the following points:
- in the daytime (from 5 am to midnight), the water temperature can be lowered by no more than 3 degrees, that is, up to 57 degrees Celsius;
- at night (from midnight to 5 am) the maximum possible reduction threshold is 5 degrees, that is, up to 55 degrees Celsius.
Suspension of DHW can occur in two situations. In the first case, we are talking about an accident. The second option is to carry out planned preventive measures... In any case, residents should not suffer and the maximum allowable hot water cut-off period is 4 hours.
Ways to find out the temperature regime of water
To defend your point of view and receive compensation for violation of rights, it is not enough to go or write to the Criminal Code. It is necessary to present them with irrefutable circumstances that not too warm water flows from the tap, preferably obtained empirically and not subject to doubt.
When an injured tenant wants to restore justice and receive compensation, you first need to find out what the indicators are in living quarters at this moment. The procedure is quite simple and short-lived. Moreover, no complicated and obscure devices are required for this.
To get the information you need, you need to arm yourself with a simple thermometer with a scale of 100 degrees. It is this device that is suitable for measuring the desired indicator. When using the device, you will need to strictly follow the given algorithm. This will provide the most accurate results possible. The procedure should be as follows:
- Open a hot water tap and wait at least 3 minutes. This makes it possible to remove the accumulated liquid, the indicators of which are slightly lower.
- Place a glass under the stream and hold it in such a way that the water overflows it. You can't just put water in a glass and take it to the table, because during this time it can cool down by a couple of degrees.
- It is important to lower the thermometer carefully into the glass closer to the center.
- After the readings stop increasing, you can write data.
If the obtained temperature is lower than the permitted one, then it will be necessary to file a complaint with the Criminal Code or the housing and communal services department. If there is no reaction, then the next instance for the complaint is the prosecutor's office and the court.
Conclusion
In conclusion, it should be noted that if the temperature regime of hot water dropped below 40 degrees Celsius, the tenant will pay for it as for cold water supply. During the violation of the current standards, the citizen also has the right to demand the implementation of the recalculation.
Conveniences such as heat, gas, electricity and water are perceived by us as components of the usual comfort of a city dweller. It is especially difficult for us without hot water, which is sometimes turned off on a planned basis.
But what if hot water can only be called that because it comes from the appropriate tap. In fact, it is a little warm, but not hot at all. Let's look at the standards and find out what temperature it should be.
Hot water temperature standard according to SNiP
Temperature range of hot water supplied to water supply systems apartment building, are established by the Sanitary and Epidemiological Service, SNIPs and GOSTs.
SanPiN decree 2.1.4.2496-09 lists the following hot water standards:
- at least 60 degrees in the open heating system;
- at least 50 degrees in a closed heating system;
- no higher than 75 degrees, regardless of the system.
The lower threshold is set in a range that allows you to protect the water from pathogenic bacteria. If the upper limit (75 degrees) is exceeded for any reason, it could damage the plastic water supply system. Such systems are now in every modern home.
The temperature of hot water from the tap must be at least 60 0 С and not higher than 75 0 С
It is worth noting that in the legislation you can find tolerances hot water temperature. They should not be more than:
- three degrees in the daytime;
- five degrees at night.
If the deviations turn out to be greater than the indicated values, consumers have the right to demand a reduction in fees. When the water in the hot tap does not reach 40 degrees in temperature, its cost should be calculated according to the standard, as for cold water supply.
How to measure the temperature of hot water in the tap
Before making a complaint and making measurements, you can independently control the temperature of the water from the hot tap. To do this, you must first open the tap and let the water flow for two to three minutes. This is necessary so that the water in the water supply system takes on a constant temperature. Then it is collected in a container where the thermometer is immersed. You can use a conventional water appliance.
After the temperature on the thermometer becomes constant, record it and take a series of measurements at another time of the day. When, during all the measurements made, the bar of the device shows a temperature below the standard, you should contact management company.
What to do if the DHW supply is not correct
It is imperative to report the inconsistency of the water temperature with the specified standards based on the results of the measurements, since you pay for the resource and have the right to demand compliance with the standards. The management company must accept applications both in writing and by phone.
All actions aimed at clarifying the causes of violations must be recorded by the dispatcher. He, in turn, is obliged to notify the applicant about the work performed on the water supply line. In the absence of problems on the water supply line, a representative of the management company (MC) must come to the address indicated in the application and take measurements. Estimated exit time is set within two hours, unless otherwise agreed with the applicant.
In the process of carrying out measurements in the presence of a representative of the UK, all thermometer readings are recorded in the report. This document must be compiled without fail. It is on its basis that one can demand recalculation of payments for hot water supply. Two copies are made: one for the applicant, the second for the Criminal Code.
If the temperature regime is violated regularly and repeatedly, the consumer has the right to contact the utility service with a complaint. It will certainly be considered, but it is important to draw up the document correctly and argue the problem as clearly as possible.
The main points of the complaint:
- In the header, in addition to the organization and the official to whom it is addressed, it is imperative to indicate your data: full name, full registration address, phone number for contact.
- The text should contain all information about the problem with an indication of the measurements made. Data is taken from an act drawn up jointly with a representative of the Criminal Code. The date when the measurements were taken, the temperature according to the readings of the device and the data of the representative must be indicated. Here you can also indicate the dates of calls and visits on this issue.
- At the end of the complaint, the requirements are prescribed to eliminate the causes of deviations from the standards.
- The complaint is sealed with the signature of the person concerned and the date of its preparation.
The complaint can be executed in printed form or by hand in duplicate. One of them is transferred to the management company. In this case, during a personal visit, you can demand to register it in the presence of the applicant and put the incoming number on the second copy, which remains in the hands of the applicant.
Sample application for measuring the temperature of hot water —
The deadline for consideration of a complaint is set at 30 days, although management companies often respond to written requests much faster. The speed of solving the problem can be affected by a collective complaint if there are several dissatisfied with the quality of the water.
In case of inaction of the Criminal Code, you should contact the state supervision structures - Rospotrebnadzor and the prosecutor's office.
According to the rules of SanPiN (2.1.4.2496-09) for an apartment, the temperature of hot water in apartment building from the tap fits within the range of 60 ° C-75 ° C regardless of the heating system. Decree (No. 354-PP RF) allows deviation:
- at night - within 5 ° C (0.00-5.00),
- during the day - within 3 ° C (5.00-00.00).
The temperature of the water in the batteries determines the temperature standard for the premises, which is –18 ° С for the living room, kitchen and separate toilet, corner room- 20 ° С, bathroom - 25 ° С. In the daytime, a deviation towards a decrease in a residential building is not allowed, at night - within 3 ° C, and in the direction of an increase - it is limited to 4 ° C. At the same time, if the temperature regime is not observed, the consumer has the right to count on a reduction in the amount of payment. However, for this it is necessary to correctly measure and take into account a number of legally stipulated requirements.
Legislative requirements
The lower temperature limit for hot water supply, according to SanPiN, is due to:
- prevention of infection by viruses and bacteria (in particular Legionella Pneumophila), which in an environment with
- minimizing chloroform content,
- prevention of skin diseases and pathological changes in the subcutaneous tissue.
If the temperature deviates by more than the permissible limit, for every 3 ° C the amount of payment during the violation period is reduced every hour by 0.1%. This time is calculated by the sum of time during the billing period. If the temperature measurements show a value below 40 ° C, payment for DHW is made according to cold water tariffs.
A possible break in the hot water supply, after which the amount of payment for each hour will be reduced by 0.15%, is:
- per month - 8 hours in total,
- at a time - 4 hours,
- on a dead-end highway in case of an accident - 24 hours.
For heating, for each hour of deviation from the norm and exceeding the permissible break, the payment is reduced by 0.15%, and the permissible break itself is:
- per month - 24 hours in total,
- at a time - depending on the temperature of the living quarters: 4 hours (8-10 ° C), 8 hours (10-12 ° C) and 16 hours (from + 12 ° C).
Detection of violation of the established temperature regime
To correctly determine compliance with the standard parameters at the point of draw-off (for example, from a tap), cooled water is drained from the pipeline within 3 minutes (no more). It is assumed that the control measurement is made in a glass, where a thermometer with a scale of at least 100 ° C is then lowered. The presence of water-saving devices, similar to the modernized aerators (http://water-save.com/), does not affect the measurement quality.
Heating quality control is carried out:
- in the largest living room,
- at a height of a meter and at a distance of half a meter from the battery,
- in the center of the planes half a meter away from the outer wall, and in the center of the room.
Owner's rights in case of deviation from the temperature range
For apartment buildings and residential buildings, the Rules governing the provision of utilities in clause 31 determine that the service company must carry out maintenance of engineering systems and recalculate for improper or untimely provision of services. That is, in the event of a violation of the temperature regime, the owners do not have to pay to eliminate the causes of this violation.
If the state of heating or hot water supply differs from that in apartments in residential buildings in excess of the agreed tolerances and presents a systemic problem, the consumer can:
- Inform the service organization about the problem and find out about its causes. In this case, it is advisable to record the appeal and data of the executor receiving the information.
- In the absence of measures taken, apply to government agencies in order to initiate an audit (in accordance with Article 33 of the Constitution of the Russian Federation). For violations of utility standards, a fine is provided (Art. 7.23 of the Code of Administrative Offenses).
- Fix the deadlines for receiving a response and eliminating the violation. Within 30 days, the official must send a response to citizens' appeals. (In the case of sending an appeal by mail, you must add the postage time). The absence of an answer threatens the official with a fine (Article 5.59 of the Code of Administrative Offenses). The deadlines for eliminating violations are not the same for different houses, however, on average, it is 45 days.
- Increase the flow of similar calls to increase the likelihood of execution. Relatives or friends can write, even if they do not live in the house.
- Contact the prosecutor's office in the absence of actions aimed at rectifying the situation on the part of authorized persons.
If the correction process is launched, then a commission (an employee of the REU and a representative of the heating network) must come to the consumer after the appeal to confirm the fact-reason for the appeal and draw up the corresponding act. After the problems are eliminated, another act is drawn up confirming this.
Utilities provided to consumers must be of high quality. Their proper implementation ensures the normal life and safety of consumers. This also applies to supplying the population with hot water (DHW). Water entering apartments and houses must meet the requirements of standards for its composition, color, smell, temperature.
What should be the DHW temperature according to the SanPiN standards, we will tell you in this article.
What are the standards set in SanPiN? Photo # 1
This mysterious abbreviation is deciphered quite simply. We are talking about sanitary and standards. These regulations are binding on everyone, and are designed to ensure the safety (harmlessness) of the resources coming to the end user.
The requirements relate to various spheres of human activity and must create a favorable environment for his life.
The legislation establishes standards for the quality of water, air, various goods, the work of enterprises, educational institutions, medical institutions. The specified rules are adopted by acts of the Chief Sanitary Doctor of the country. For violation of the established regulations, the application of certain measures of responsibility is envisaged.
Where are they used?
Where do sanitary norms for hot water supply apply? Photo # 2
Hygienic and sanitary standards have a fairly wide range of uses. They operate in trade, education, medicine, and the provision of public services. Its own rules have also been adopted in the field of hot water supply to consumers (SanPiN 2.1.4.2496-09). They relate to the quality of the supplied water, its temperature regime, and the operation of centralized hot water systems.
The water supplied to consumers should be distinguished by a harmless composition, the absence of infections, harmful bacteria. In addition, during its supply, the level of contamination, chlorination must be ensured.
The requirements established by this standard must be complied with by all organizations, entrepreneurs, institutions and bodies related to hot water supply without exception. They apply to various types of DHW systems.
About the requirements for STsGV
What are the requirements for STSGV? Photo # 3
The requirements stipulated by SaiPiNs relate not only to the quality of the water itself, but also to their supply systems as a whole. Purification, water supply should be carried out by specialized organizations using safe proven materials, equipment, chemical active substances.
When designing the SCHW, the type of system is selected based on the indicators of the initially incoming water.
In total, there are three types of systems:
- connected to closed heat supply systems;
- to open heat supply systems;
- STsGV with separate networks.
With SCHV, the standards established for the safety and normal functioning of the system must also be taken into account. During their operation, the required water temperature must be observed. In places for water intake, it should not fall below + 60 ° Celsius.
It is necessary to constantly monitor the quality of the supplied water, including taking preventive measures. DHW systems must undergo flushing and disinfection procedures. Interruptions in the water supply in such cases should not exceed fourteen days.
Requirements for the quality and temperature of DHW
What quality and temperature should hot water be supplied to residential apartments? Photo No. 4
The provisions of SanPiN 2.1.4.2496-09 entitled "Hygienic Requirements for Ensuring the Safety of Hot Water Supply Systems" indicate the following. The consumer must receive water from the tap that has passed all degrees of purification and meets all the requirements and rules of safety and hygiene. These standards are designed to ensure its harmless composition, normal color and odor.
Hot should come with a certain temperature to avoid the development of various infections and bacteria. According to SanPiN, the incoming water cannot be colder than sixty degrees and hotter than seventy-five degrees. Hazardous untested substances cannot be used in water purification. Its quality should allow avoiding infection, as well as skin problems.
Recalculation when the temperature does not comply with the standards
Despite the existence of standards that establish the required water temperature, their violation is sometimes omitted. If the water does not correspond to the norm for its temperature, do not leave it unattended. All utility services must be of high quality and meet the established requirements. Their violation entails certain consequences.
It should be borne in mind that the legislator provides for the possibility of minimal deviations from the norm that do not entail negative consequences. Permissible deviations, depending on the day, can range from three to five degrees. If a greater difference is revealed, the consumer has the right to demand the elimination of violations.
In addition, it is possible to recalculate the payment for the entire time when the water does not correspond to the provided temperature regime. if the temperature was below the standard, then it is worth paying for hot water supply at the rates for cold water. According to the existing recalculation formula, the amount of payment is reduced by 0.1 percent for every three degrees of deviation from the norm.
Features of the measurements
How to measure hot water for quality and temperature? Photo No. 5
It makes no sense to say that the DHW temperature does not correspond to the norm. This fact must be established using special measurements. They must be produced by specialists using certain techniques and equipment. These measurements are taken at several points of the water intake.
In this case, after opening the tap, several minutes should pass. taking measurements immediately is not recommended.
Calling a specialist is carried out at the request of the tenants (owners) of apartments (houses). Based on the results of the check, an act of violation of the temperature norm should be drawn up. On its basis, it will be possible to demand elimination and recalculation.
Why do you need a water temperature norm?
The standard for the permissible limits of the DHW temperature is set for a reason. Its lower limit allows you to rid the water supplied to consumers from various infections and harmful bacteria. At lower temperatures, they can develop and multiply, causing harm to humans.
If the water temperature is too high, there is a risk of burns. Therefore, experts have set the optimum temperature that meets all of the listed requirements.
conclusions
Hot water supplied to consumers must comply with established standards. This is not only comfort, but also safety for human health and life. In the event of violations of its temperature regime, housing and communal services workers should be notified of this. Deviations determined by measurements will serve as the basis for eliminating violations and recalculating payments for hot water supply.
