Such amenities as heat, gas, electricity and water are perceived by us as components of the usual comfort of a city dweller. It’s especially difficult for us without hot water, which is sometimes planned to be turned off.
But what if hot water can only be called that because it comes from the corresponding tap. In fact, it is slightly 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 conditions 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 an 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 water from pathogenic bacteria. If the upper limit (75 degrees) is exceeded for any reason, it may cause damage plastic system water supply These are the systems now in every modern home.
The temperature of hot water from the tap should not be lower than 60 0 C and not higher than 75 0 C
It is worth noting that in legislation you can find permissible deviations in hot water temperature. They should not be more than:
- three degrees during the daytime;
- five degrees at night.
If the deviations turn out to be greater than the specified values, consumers have the right to demand a reduction in fees. When the water in a 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 a tap
Before filing a complaint and requesting measurements, you can independently monitor the temperature of the water from the hot tap. To do this, you first need to 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 regular water appliance.
After the temperature on the thermometer becomes constant, write it down and take a series of measurements at other times of the day. When, during all measurements taken, the instrument column shows a temperature below the standard, you should contact management company.
What to do if the DHW supply is not normal
It is necessary to report a discrepancy between the water temperature and the specified standards based on the results of measurements taken, 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 telephone.
All actions aimed at identifying the causes of violations must be recorded by the dispatcher. He, in turn, is obliged to notify the applicant about the work being carried out on the water supply line. If there are no problems on the water supply line, a representative of the management company (MC) is obliged to come to the address specified in the application and take measurements. The estimated exit time is set at two hours unless otherwise agreed with the applicant.
In the process of taking measurements in the presence of a representative of the management company, all thermometer readings are recorded in a report. This document must be completed. It is on this basis that you can demand a recalculation of the payment for hot water supply. Two copies are drawn up: 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 definitely be considered, but it is important to draw up the document correctly and argue the problem as clearly as possible.
Main points of complaint:
- In the header, in addition to the organization and the official to whom it is addressed, you must indicate your data: full name, full registration address, contact phone number.
- The text must contain all the information about the problem indicating the measurements taken. Data is taken from the act drawn up jointly with the representative of the management company. The date when the measurements were taken, the temperature as measured by the device and the data of the representative must be indicated. Here you can indicate the dates of requests and visits on this issue.
- Finally, the complaint states requirements to eliminate the causes of deviations from the standards.
- The complaint is sealed with the signature of the interested person and the date of its preparation.
The complaint can be submitted in printed form or by hand in two copies. 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 entry number on the second copy, which remains in the applicant’s hands.
Sample application for measuring hot water temperature —
The period for consideration of a complaint is set at 30 days, although management companies often respond to written requests much faster. A collective complaint may affect the speed of solving the problem 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.
SanPiN regulations strictly establish what the temperature of hot water in an apartment should be - the 2019 standard remained unchanged compared to the previous year. This means that all Russian citizens have the right to use hot water a certain temperature (for which, by the way, they pay) and complain when faced with violations of SanPiN regulations. And the point is not at all that along with water the citizen is deprived of basic amenities - if the water flowing from the tap is too cold or too hot, the health of the person who uses it is at risk.
What standards are established?
What temperature should the hot water be? This directly depends on the type of water supply system:
If the system is open - minimum 60 degrees Celsius.
IN closed system – minimum 50 degrees Celsius.
According to 2019 standards, the temperature of hot water in the apartment should not exceed 75 degrees. This limit does not depend on the type of water supply system.
Temperature control is extremely important for a number of reasons.
If the temperature is too low, the fluid becomes contaminated with pathogens infectious diseases and bacteria. At a set minimum temperature threshold, harmful bacteria are doomed to death.
Water that is too hot can cause skin damage (burns). Strictly speaking, even at 55 degrees there is a risk of burns - therefore, citizens connected to open water supply systems are advised to “mix” cold water with hot water.
Exceeding the temperature threshold leads to damage to the plastic elements of the water supply system - but in most cases modern apartments The water supply is mostly made of plastic. Who should pay for repairs in this case is a big question. The entire time the citizen is looking for the culprit and proving his right to compensation, he will have to sit unwashed.
Temperature drops to 59 degrees or rises to 76 degrees open system water supply is already considered a violation of the Rules for the provision of public utilities (there are some). However, these Rules still allow minor deviations from temperature limits.
It is allowed to lower the temperature during the day (from 5 am to midnight) by 3° Celsius - that is, to 57°.
At night (from midnight to 5 am) it is permissible to lower the minimum threshold by 5° - that is, to 55°.
The supply of hot water can be stopped completely in 2 cases: if pumping station or there is an accident in the supply line or if scheduled maintenance work is being carried out. In case of prevention, citizens have no right to be deprived of water supply for more than 4 hours.
How to measure temperature?
Of course, it is useless to go to the management company with unfounded accusations that “what comes out of the tap is a little lukewarm” - provide them with evidence. Therefore, a citizen who considers himself a victim due to violations of SanPiNA regulations and wants to defend justice must first of all learn how to measure the temperature of hot water in an apartment. This procedure is simple, short-term and does not require sophisticated improvised means.
A thermometer with a scale of 100 degrees is how you measure the temperature of hot water in a tap. For measurement, a citizen must prepare this household appliance, then strictly adhere to the algorithm of actions, which, according to management companies, invariably leads to accurate results.
Open the tap and let the water drain for about 3 minutes. This way they get rid of stagnant water, the temperature of which is traditionally lower.
Place a glass under the stream and hold it so that the liquid overflows over the edges. You can’t just take a glass from the tap - by the time you bring it to the table where you put the thermometer, the water will have cooled down, and the reliability of the measurement will be questionable
Lower the thermometer into the container closer to the center.
Wait until the degrees on the device stop increasing and record the result.
If the thermometer showed a temperature below the minimum level established by SanPiN, this means that it is time for the management company to give a formal thrashing.
Where to contact?
What to do if the hot water is at a low temperature? A citizen needs to complain about this to the Housing and Communal Services (HCS).
Insufficiently high temperature is only one of the grounds for complaint. Housing and communal services should also be concerned if the water has an uncharacteristic color (smell, taste) or is completely absent.
There is no need to personally visit the Farm - you can call. The dispatcher will first check whether the decrease in the temperature of the hot water in the tap is caused by a breakdown in the main line or preventive work. If repairs at the station are to blame, the dispatcher will inform the citizen of the approximate time frame for when normal water supply will be restored. If there are no valid reasons for violating SanPiN regulations, the dispatcher will record the citizen’s request and promise that you won’t have to wait long for a reaction.
In order to be sure that his appeal will not be ignored, the citizen needs to write down the application number, the time of the call to the housing and communal services and the name of the employee with whom he communicated. An employee faced with such meticulousness will definitely make sure that the application he accepts is considered - because he will feel responsible for fulfilling the promises made.
The citizen needs to wait for the visit of the expert - according to Government Resolution No. 354, the expert should appear on the doorstep no more than 2 hours after the citizen files a complaint. The expert will measure the temperature of the tap water himself (of course, no one will take the citizen’s word for it). Then the housing and communal services employee will draw up a report in which he will describe whether a violation actually took place, how and when the measurement was carried out. The consumer of utilities will receive one of the copies of the act in hand - the expert will take the second copy with him.
Having with you a certificate indicating a violation of hot water temperature standards in apartment building, a citizen has the right to demand from the management company a recalculation of the payment for hot water supply.
For hot water, the temperature of which drops below 40° Celsius, the service consumer pays as for cold water.
Resolution No. 354 states that the period during which a citizen has the right to recalculate ends when people from the management company come to the citizen’s home and carry out a final check, which confirms that the hot water temperature is high enough. If the recalculation is refused, the citizen should file a complaint against the actions of the management company with Rospotrebnadzor or the magistrate’s court.
We are accustomed to the amenities that are available in our homes. Electricity, heating, gas - all this an integral part of our comfort.
Hot water is one of the most popular services. You realize this especially acutely in the summer season. during a planned water outage, but this lasts a short period.

What is the legal service life of a gas meter, and what to do if it is expired? find out right now.
What should the quality be?
What do SNIPs, GOSTs and SanPins say? In accordance with the Resolution of the Sanitary and Epidemiological Service (SanPiN 2.1.4.2496-09 clause 2.4) certain standards have been introduced on the temperature regime of water delivery to residential premises.
This document specifies the temperature limits for water supplied to apartments. They range from 60°C to 75°C.
It was not in vain that this range was chosen. If the temperature at the entrance to a residential building is above 75°C, then the likelihood of getting burn injuries will increase several times. This is especially true for children's and medical institutions.
At a threshold below 60°C risk of growth of infectious pathogens, such as legionella, increases in warm environments. At 70°C-80°C complete disinfection occurs. An indicator of 40°C promotes best reproduction this bacterium.
The SanPiN Resolution, paragraph 2.2, states that the water supplied to residential buildings must be of high quality: without unpleasant odor, without any aftertaste.
Must be observed compliance with sanitary and epidemiological standards. In case of violations, organizations supplying utility services need to establish the reason for the supply and eliminate it.
Permissible deviation at the point of water collection
Government Resolution No. 354 adopted acceptable standards deviations temperature regime hot water supply:
- for night time from 00:00 to 05:00 they correspond to 5°C;
- for daytime from 05:00 to 00:00 – no more than 3°C.
Moreover, if the deviation from the standard is greater than these values, then for every 3°C it is possible demand a reduction in utility bills by 0.1% per hour deviation.
If the device shows a temperature of 40°C and below, then payment must be made according to the standards cold water. But for this it is necessary to have an official measurement report confirming the deviation from the norms.
How to write a complaint?
At repeated violation The temperature regime for hot water supply should be sent to utilities.
It is important that this document is drawn up competently and well-reasoned.
In the header of the document, you should correctly indicate which organization and, if the specific name of the responsible person is known, to whose name the complaint is sent.
The title of the complaint is written:
- Statement of violation of regulations providing the population with utilities in accordance with Federal Law No. 195, Article 7.23
- The text of the statement states essence of the problem. It is necessary to mention the measurement carried out and enter information from the drawn up report: date of conduct, full name of the employee who carried out the measurement, water temperature.
- At the end of the text of the complaint, a requirement is written to eliminate the reasons causing failures in the supply of hot water. It is worth pointing out the need to inform the applicant about the work performed.
- The document ends with the date of its preparation and the signature of the applicant.
It is important to set the period, for which recalculation must be made.
The beginning of the period is considered to be the date specified in the official act, and the end should be the date when final check completed after eliminating the reasons for supplying water that does not meet temperature standards.
If recalculation is refused, you should go to court.
In cases of violations in accordance with Federal Law No. 195, Article 7.23, persons those found guilty may be subject to fines: for officials the amount of the fine will be from 500 to 1000 rubles, for an organization - from 5000 rubles to 10000 rubles.
When paying for utilities, any user wants to get a quality product for their money. That is why you should not give up if lukewarm water flows out of the tap.
Knowing the hot water temperature standards, you can try to influence the services supplying utilities: take measurements, draw up a report, make a recalculation, file a complaint with a higher authority.
About providing public services on hot water supply of inadequate quality and reduction of fees for hot water.

1. General provisions and scope
1.1. The sanitary and epidemiological requirements for ensuring the safety of water in centralized hot water supply systems include the prevention of contamination of hot water by highly contagious infectious pathogens of viral and bacterial origin that can multiply at temperatures below 60 ° C (including Legionella Pneumophila), as well as the prevention of skin diseases and subcutaneous tissue, determined by the quality of hot water.
1.2. In accordance with the hygienic requirements for ensuring the safety of hot water supply systems, the temperature of hot water at water points, regardless of the heat supply system used, must be no lower than 60 °C and no higher than 75 °C.
1.3. These guidelines establish a method for measuring the temperature of hot water in centralized hot water supply systems, used in monitoring (supervision) compliance with the requirements of SanPiN 2.1.4.2496-09* " Hygienic requirements to ensure the safety of hot water supply systems. Amendment to SanPiN 2.1.4.1074-01 "(hereinafter referred to as SanPiN 2.1.4.2496-09).
* Approved by resolution of the Chief State sanitary doctor Russian Federation dated April 7, 2009 No. 20, registered by the Ministry of Justice of Russia on May 5, 2009, registration number 13891.
3.3. When carrying out measurements, the flask (sampling container) is placed on a stand with a tray. The flow of sampled water is directed to the collection tank. Measurements can be taken using a washbasin, bathtub, etc. as a tray.
4. Safety requirements for measurements
When collecting hot water samples and making measurements, you should use personal protection, preventing hot water from entering exposed parts of the body.
5. Operator qualification requirements
Trained specialists with experience in this field of activity are allowed to perform measurements and process results.
6. Measurement conditions
Sampling and measurement of hot water temperature should be carried out indoors at an air temperature of 20 - 35 ° C, humidity 30 - 80% and atmospheric pressure 84 - 106.7 kPa.
7. Sampling and measurements
7.1. Sampling for the purpose of conducting research for the purposes of state sanitary and epidemiological supervision and production control is carried out in accordance with the requirements of SanPiN 2.1.4.2496-09 at water collection points.
7.2. At least 4 points are selected for water selection: 2 closest to the hot water network entry into the facility (building) and 2 most distant from it. The selection of points is carried out according to the technical documentation for the facility where control measurements are made.
7.3. Hot water temperature measurements are carried out in the warm and cold periods of the year at an outside air temperature that differs by no more than 5 °C from average temperature the warmest summer month and the average temperature of the coldest month winter month of the year. Measurements for complaint resolution purposes can be carried out in all weather conditions.
7.4. For the purpose of production control, it is possible to carry out additional measurements at various stages of water preparation in the hot water supply system.
7.5. Before taking hot water samples, drain the water until the constant temperature. The water draining time can be up to 10 minutes, depending on the state of the distribution network and the hot water consumption mode of the consumer. When taking samples at the point where hot water is supplied to the distribution network, the water is not drained. The sample is taken into a container that meets the requirements of paragraph of these guidelines, with a continuous flow of water. The water flow rate must be at least 2 liters per minute (determined by the time it takes to fill the measuring container). When taking a sample and carrying out measurements, excess water is poured over the edge of the sample container into a tray, and from it is removed into the sewer.
7.6. To measure the temperature of the sampled hot water, the thermometer is immersed in the water being tested so that the thermometer ball (or SI sensor) is approximately in the center of the sampling container. Measurements are carried out with a continuous flow of water into the container. The measurement result is recorded after establishing stable SI readings, but no more than 10 minutes after the start of sampling.
8. Processing and presentation of analysis results
The measurements taken are direct measurements with a single observation. The measurement results are presented in the form:
X±U(P= 0.95), where
X -measured temperature value;
U- expanded uncertainty of the measurement result, calculated in accordance with metrology recommendations
