What should be the temperature hot water in the tap? Standards, the largest and smallest value as well as the permissible deviations are spelled out in SanPiN 2.1.4.2496-09. In this article, we will tell you where to file a complaint if the water temperature is below normal.
Resource supplying organizations are obliged to comply with the rules for providing the population with utilities. In case of hot water they relate to its pressure, composition and temperature. Responsible organizations are familiar with these criteria. Citizens are not always aware of them, although they also need it to assert their rights.
What should be the temperature norm?
The norm of hot water temperature in MKD is determined in clause 2.4 of SanPiN 2.1.4.2496-09. This range is + 60… + 75 ° C and remains unchanged for many years. It does not require changes, since it is based on the characteristics of human physiology and accompanying microflora.
The lower threshold of + 60 ° C is determined, first of all, by the survival rate of some pathogens of dangerous infectious diseases. For example, this includes bacteria that cause legionellosis. They multiply well in a warm environment, and die when the temperature rises. To completely disinfect hot water from the tap, you need to heat it up to + 70 ... + 80 ° C.
If the temperature drops to + 40 ° C, then the most favorable conditions for the reproduction of microorganisms dangerous to humans. This is easily explained. The temperature of + 40 ° C is very close to the natural temperature of the human body and all fluids circulating in it.
Heating above + 60 ° C is set for water in open systems. This is where the water pipes laid in multi-storey buildings... However, there are also closed water supply systems, for example, which do not go beyond individual buildings. They have a significantly reduced risk of microorganism ingress, therefore, the minimum water temperature threshold is + 50 ° C.
The upper value of the hot water temperature in the tap according to the standard (+ 75 ° C) was selected for safety reasons. With its further increase, the risk of burns increases significantly. Children, senior citizens and people with disabilities are thus insured against dangerous injuries at home.
The norms prescribed in SanPiN are supplemented by government decree No. 354. It indicates the deviations that are allowed for the hot water temperature:
- from midnight to 5 am they are 5 ° C;
- the rest of the time (it is considered daytime) - no more than 3 ° C.
If the temperature of hot water in an apartment building is not observed, then the tenants have the right to recalculate the payment for this service. Every three degrees of deviation will reduce pay by 0.1 percent for one hour of non-compliance.
When the temperature of hot water drops to + 40 ° C or less, it is paid at the prices of cold water supply. Such a recalculation is done on the basis of an act confirming the officially carried out measurements.
Existing standards and amendments to them allow you to calculate the minimum permissible temperature hot water. In the daytime it is + 57 ° C, at night - + 55 ° C.
Temperature measurement methods
If there is a suspicion of a mismatch in the temperature of the hot water in the tap existing regulations, then you need to make its measurements. Residents are better off doing this on their own first. So they can be convinced of the validity of the accusations to the side resource supplying organization... After that, you can safely send a request for measurement by specialists with the preparation of an official act.
For self-measurement you will need a medium-sized container and a household thermometer that can measure the temperature, at least up to + 100 ° C. Further actions will be described in steps. The procedure takes only a few minutes, so for persuasiveness, you can make a photo or video recording.
1. The tap opens and water flows freely into the drain for 2-3 minutes. This is enough for the descent of water stagnant in the pipes inside the house, which has already cooled down a little.
2. The container is placed under the stream and is positioned so that water can flow freely over its edges. Pour water into a saucepan, take it to the table and you cannot immerse the thermometer there. While all these manipulations are being performed, the liquid in the container gradually cools down, and the measurements turn out to be unreliable.
3. The thermometer is lowered into the water in the central part of the tank. At the edges, the water, again, has time to cool down a little.
4. When the column on the thermometer stops rising, you can record the results. If they differ from the values established in the standards, then you should contact the managing organization.
Reasons for lowering the temperature of hot water
Despite the existence of norms for the temperature of hot water, in some cases it can decrease, and this is not considered a violation, although the residents apartment building and are uncomfortable. This usually happens when:
- accidents occur on equipment that heats water and on the networks through which it is transported;
- the resource supplying organization carries out the planned preventive maintenance or repair.
To protect the rights of the population to high-quality provision of communal resources, deadlines have been set for shutting down hot water supply:
- up to 4 hours in a row;
- up to 8 hours in total within a month;
- up to 1 day in an emergency.
Where to file a complaint
If the temperature of hot water in the tap actually differs from that set by the standard, then you need to call the representatives of the managing or resource supplying organization and find out the reasons. It is possible that work is already underway and the problems will soon be fixed.
If the violation is not repeated for the first time and is persistent, then defending your rights should be approached with the utmost seriousness. First of all, a complaint is written. It must be a competent and well-reasoned document, from which responsible organization won't be able to brush it off.
At the top of the sheet, the name of the organization to which the complaint is sent is indicated. The addressee can also be a specific person in charge. After that, the applicant indicates information about himself: full name, address and apartment number in which the violation is recorded, telephone numbers for communication.
1. Title. It should be something like this: "Statement of violation of the provision of utilities to the population ". The title is required to be clear and written in a language that officials understand.
2. Description of the essence of the problem. Here, 1-2 sentences are enough, without sharp and emotional turns, as well as without unnecessary information. Without fail, it is said about the measurement carried out, and information from the drawn up act is provided:
- temperature readings;
- information about the specialist who carried out the measurements;
- date of measurement.
3. Requirements. Even if it seems logically clear what a citizen wants to receive in case of violation of the norms of hot water temperature in an apartment building, this information should be prescribed. Otherwise, the actions of the responsible persons and organizations may be protracted, minimal and incomplete. The following requirements are usually indicated:
- eliminate the causes of interruptions in hot water;
- recalculate;
- inform the applicant about the work performed.
Other items can be added. Each of them, the recipient will have to consider and implement, or, if it is impossible to fulfill, justify it.
4. Date of writing the complaint and signature of the person submitting it.
The complaint is made in two copies. First of all, it must be attributed to the Criminal Code or Homeowners' Association, even if they had previously ignored signals of poor-quality service. To go further, you need a refusal to solve the problem or accept the complaint. If a citizen is convinced that managing organization ignores him, then he can go:
- to the State Housing Inspection;
- to Rospotrebnadzor;
- to the local administration;
- to the prosecutor's office.
In most cases, the intervention of housing inspectors or prosecutors is sufficient. They actively defend consumer rights. Upon confirmation of violations, the organization is usually fined, and also undertakes to eliminate the problems and recalculate. The execution of this order is monitored by the representatives of the regulatory authorities who issued them.
In the most difficult cases, a citizen has to independently go to court and seek support in the local media. This happens when the same employees of the State Housing Inspection and the Prosecutor's Office do not perform their duties thoroughly enough.
The hot water temperature depends on both the type of water supply system and 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 regulations 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.
IN 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 during the night period (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. With hotter water than the standard, you can burn yourself with varying degrees 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 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 the cold water must 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 is possible that you do not have 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 good reason no, 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.
Permissible deviation at the point of water intake temperature regime hot water supply:
- for night time from 00:00 to 05:00 they correspond to 5 ° С;
- for daytime from 05:00 to 00:00 - no more than 3 ° С.
Moreover, if the deviation from the standard is greater than these values, then for every 3 ° C it is possible to require a decrease in utility bills by 0.1% per hour of 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 certificate confirming the deviation from the norms. Sample application in management company on the hot water temperature. to the content Minimum indicator The minimum temperature threshold for hot water supply is determined at 60 ° С.

When paying for utilities, any user wants to receive a quality product for their money. That is why you should not give up if lukewarm water flows out of the tap.
Important
Knowing the standards for the temperature of hot water, you can try to influence the services that supply utilities: make measurements, draw up an act, make a recalculation, file a complaint with a higher authority. A statement of claim for the provision of public services for hot water supply of inadequate quality and a reduction in the payment for hot water.

Rules for measuring the temperature of hot water. which document to believe?
That is, a water temperature of 59 or 76 degrees for an open water supply system will be a violation. There are several exceptions to this rule:
- Downgrade is allowed from 5 am to midnight minimum temperature by 3 degrees Celsius, that is, up to 57 degrees with an open system;
- From midnight to 5 in the morning, it is permissible to lower the standard by 5 degrees - to 55.
Interruption of hot water supply is also allowed in some exceptional cases:
- Accident on the water supply line;
- Preventive maintenance (shutdown is possible for no longer than 4 hours).
Where to contact in case of non-compliance with the standards If during the measurement it turned out that the water does not correspond to the temperature, established by the standards, any citizen can demand the elimination of violations from the management company.
Standard and permissible deviation of hot water temperature in the apartment
Attention
Water sampling from the consumer's tap Water sampling is carried out at the outlet from the taps of the internal water supply networks of houses. When sampling from a consumer tap, the time to drain the water before sampling depends on the purpose of sampling.
If the purpose of sampling is to assess the effect of materials in contact with water on water quality, then samples should be taken without first draining the water. For other purposes, 2-3 minutes of draining the water is sufficient to establish equilibrium conditions before sampling.

You can also complain to the organization of housing and communal services when the water from the tap has an unnatural smell or color. To begin with, the consumer needs to call the management company and tell about the problem that has arisen.
Info
The company's specialist will check whether the change in water temperature is associated with a breakdown or preventive work on the mains and will inform the preliminary time of completion of the work, if the reason is in them. If the non-compliance with the hot water temperature in the apartment is caused by another reason, the dispatcher must record the citizen's appeal and hand it over to the authorized employees of the company for consideration.
You may need the following examples of complaints: Complaint in housing and communal services for non-compliance with hot water standards Complaint to the prosecutor's office for non-compliance with hot water standards A citizen has the right to demand from the dispatcher to name his full name and application number assigned to her in the journal.
Rules for measuring the temperature of hot water in an apartment
Of the Rules for the Provision of Utilities to Owners and Users of Premises in apartment buildings and residential buildings "(approved by the Decree of the Government of the Russian Federation No. 354 of May 6, 2011):" ... BEFORE DETERMINING THE TEMPERATURE OF HOT WATER AT THE TAKING POINT, THE WATER IS DRAINED WITHIN NO MORE THAN 3 MINUTES. " Methodical instructions MUK 4.3.2900-11 ″ Measurement of hot water temperature of centralized hot water supply systems ”(approved by
Fed. service Rospotrebnadzor July 12, 2011) found that when draining "... Water consumption must be at least 2 liters per minute (determined by the time the measuring container is filled)." every degree of hot water is a lot of money in his pocket!) to the chief engineer.
Do not let the meter open the tap at full power, so that the spray will fly right up to the ceiling and it will not be the temperature of the water in your tap that is measured, but the temperature of the water in the supply line at the entrance to the house, or in the boiler room. alternately - I subtracted, she added. As a result, I wanted to record in the act the real water consumption measured by the meter and by the "measuring capacity", but the commission snatched the act from my hands and took it away without my signature. But when the lawyer of housing and communal services tried to attach this act to the case the statement that "... THE ACT WITHOUT MY SIGNATURE IN ACCORDANCE WITH" RULES No. 354 "CANNOT HAVE LEGAL EFFECT ..", the judge refused this lawyer.
Be prepared for the fact that Chief Engineer will show his knowledge and in response will “poke under your nose” the text “… Before taking samples of hot water, drain the water until a constant temperature is established.
RosZhKH “all project ideas Yesterday Rospotrebnadzor measured the hot water supply temperature in the apartment (as they explained to me, according to METHODOLOGICAL INSTRUCTIONS MUK 4.3.2900-11). After a ten-minute drain (no one measured the speed of the water), the temperature was 68 degrees.
