Temperature regime of hot water supply. Temperature norm for hot water

What are the requirements for hot water? On what indicators does the quality of hot water supply depend? Regulatory documents that regulate the characteristics of the hot water environment in our homes. The main norms of hot water supply. Requirements for hot water in public institutions. Basic indicators of hot water, their maximum permissible values. Requirements for hot water are stipulated by the current GOST 2874-82. The quality of hot water supply must comply with hygiene standards for drinking water supply.

Basic norms of hot water

Although hot water is not recommended to be drunk, but only used for domestic needs, the requirements for it are the same as for drinking water supply systems. After heating, the water must comply with the sanitary and hygienic requirements for water consumption. At the same time, very strict requirements are imposed on the temperature of such water. Both upper and lower temperature limits are limited:

Hot water in our pipes must be heated to at least 60 degrees. This temperature indicator is not accidental, because at this value most of the dangerous bacteria and microorganisms die.
The upper temperature limit for water in our homes is set at 75 degrees. If this value is exceeded, there is a high risk of burns.

Wherein normative documents also regulates the requirements for temperature in places of water consumption. These requirements for hot water supply are specified in SanPiN 2.04.01-85. In this case, the following temperature values \u200b\u200bare indicated:

In networks of centralized hot liquid supply adjacent to closed heating plants, the temperature values \u200b\u200bshould be at least 50 degrees.
In hot water networks of centralized water supply connected to open heating plants, as well as for non-centralized networks of hot water, the normalized temperature indicator is 60 degrees.
The upper limit in any situation is set no higher than 75 degrees.

Requirements for hot water in public institutions

As for the hot water that is supplied to the taps of washstands, showers in the facilities of organizations social purpose, as well as in kindergartens, schools and other institutions intended for the stay of children, then the temperature indicators of the hot water environment cannot exceed 37 degrees. The same applies to all medical institutions.
If in all the above organizations and institutions it is required to use hot water of a higher temperature, then it is obtained through the use of local water heating devices (boilers and furnaces). These heaters can be gas or electric. For example, such a situation may arise in the part of institutions intended for the nutrition of children and adults. Here you need to wash dirty dishes, and for this it is necessary to use water with temperature values \u200b\u200bof at least 75 degrees.

hot water quality requirements

Since the hot water environment must meet the requirements of drinking water supply, water is also supplied from the drinking water supply system. It is strictly forbidden to produce an aqueous medium of drinking properties in the place where water is heated or where this liquid is consumed.

Since when the water is heated, the likelihood of scale buildup increases. inner surface pipelines, as well as the speed corrosion processes, water for hot centralized water supply must meet the following requirements:

The content of oxygen dissolved in the liquid must be within 0.1 mg/l.
The concentration of suspended impurities is allowed no more than 5 mg/l of liquid.
The temporary hardness of the water should be within the normal range of 1.5 mg/l.
The total hydrogen number is allowed within the range of 8.3-8.5 pH.
The concentration of ferrous compounds can be no more than 0.3 mg/l.
The oxidizability of the aquatic environment is allowed equal to 6 mg/l.
Normally, free particles of carbon dioxide should not be detected in such water.

As you know, when water is heated above 40 ° C, the carbonate hardness of the aquatic environment increases very much. All this can lead to scale on the pipes, which can clog the patency of the pipe. That is why the indicator of the hydrocarbonate hardness of the aquatic environment is very carefully controlled.

If you want to test the quality of hot water supply, you can order such an analysis from our independent licensed laboratory. We have passed state accreditation, so all test results will be legally binding. The cost of the analysis depends on the number of monitored indicators and is specified when ordering a check by phone.

The temperature of hot water in the tap according to the standard in 2019 is regulated by SNiP (building codes and regulations) N II-34-76 and SanPiN 2.1.4.2496-09. These documents determine the quality of water supplied to residential buildings for household and drinking needs.

Poor quality of tap water

In addition to temperature, hot water must comply parameters such as purity and pressure. What is the use of hot water if it runs in a thin stream or is dirty? High blood pressure is also not a reason for joy: this entails a breakdown of couplings, valves and other elements of the water supply system.

For hot water, pressure limits are set from 0.3 to 4.5 atmospheres. Going beyond these boundaries is a direct reason for applying to the Criminal Code for recalculation.

Impurities in the aquatic environment can be both organic and inorganic origin: rust, getting into the earth system, rotting wood, etc. If such cases are frequent and prolonged, it is necessary to file a complaint with the water utility with a request to inspect the treatment systems, which should be carried out jointly with the housing office.

How to file a complaint?

Individuals living in different cities of Russia have slightly different temperatures cold water in the tap. In this regard, the question automatically arises of how many degrees the water should be according to the current state standard, and also why some residents have it colder than others. It will also talk about what measures need to be taken by individuals who are dissatisfied with the temperature, as well as the quality of the water entering their homes.

Since the cold water generator that enters the residents' taps apartment buildings, is an centralized water supply, then its temperature, depending on various factors, may vary slightly. These factors include the time of year, how the pipelines are placed, what condition they are in, and many other details. However, there is a general state standard that dictates the temperature norm of water, which must be observed despite the circumstances.

It should be noted that executive authorities A number of normative acts concerning building norms and rules were adopted. This source indicates the norms of relative cold water supply of residential premises, which must be observed.

Building regulations

In the current housing code Russian Federation it is fixed that tenants who systematically pay a certain price for supply to their homes water resources should receive them in the amount that they need for a comfortable stay. In addition, the composition of the water must be safe for human health and not contain any hazardous impurities. However, in such a source as building codes and regulations, it is prescribed that residents will be provided with drinking water only if it is supplied through pipelines that meet all sanitary standards.

IN different regions Russian Federation, water quality varies considerably. In this regard, the current legislation states that temperature indicators, depending on certain quality characteristics, may vary slightly in different cities and even districts. Also, the building codes and regulations show that for one month there may not be water in the taps of individuals for a total of no more than eight hours. In addition, if on the same day residents are denied water supply for more than four hours in a row, then this is considered an offense.

The warmth of water resources generated by a cold main does not affect the level of comfort of living for individuals. The same fact applies to sanitary conditions. Regarding the pressure that should be in the cold water supply circuit, the building codes and regulations state that the minimum value of this indicator is 0.03 MP, and the maximum is 0.6 MP.

What does GOST say

As for the temperature indicators of cold water supplied to the dwellings of citizens of the Russian Federation, on this topic in state standard practically nothing is said. However, the quality and composition of water resources should be described in this source in some detail. Regarding the temperature characteristics of cold water, the following rules apply:

The water temperature depends on the season. In the warm season, the water that is supplied to the residents' taps will be slightly warmer than in the cold seasons. This fact is directly related to weather conditions. Water entering a special facility, which was created to take water from a source, will be much warmer in summer than in winter. In addition, a hydraulic structure designed to supply and divert water resources in a certain direction, called a conduit, is located close to the soil, the temperature of which also affects the temperature of the water.
Temperature standards are set by the supplier. Since the current legislation did not regulate temperature indicators that are directly related to cold tap water, then each individual organization that is a provider of services of this nature independently determines these values. In most cases, the minimum limit is set at four degrees Celsius, and the maximum at twenty degrees.

How to achieve an acceptable water temperature

Since the cost of using utilities is quite high in 2019, the demand from their suppliers is also growing. Thus, if an individual is categorically dissatisfied with the temperature of cold water and / or its quality, then he needs to file his claim in writing. This is done in the form of a special act. After that, this document must be noted in the registration log, and the provider of a certain utility service must review it within three days.

Attention! If the supplier did not react in any way to the drawn up act, which was signed by more than two tenants, and at the same time the quality of the service provided was not checked, then the document expressing a certain claim is automatically recognized as valid.

How to draw up an act

In order not to completely write the entire document by hand, we strongly recommend that you print out its form, which is freely available and is called the “Claim Act”, and enter the relevant information in the empty lines. First of all, in the empty form of the act, you must enter the name locality, and then the day, month and year of the conclusion of the document. This is followed by the following information:

About the consumer and the performer. If the consumer of cold water observes that the supplier violates the norms of the agreement concluded between them, then he has full right Complain in order to restore justice. First of all, the number of the agreement is prescribed, and then the last name, first name and patronymic of the user, as well as the type of a certain utility service, the quality of which is dissatisfied with the individual. After that, it is specifically listed what the essence of the claims is.
About indicators. Simply expressing your dissatisfaction with the quality of housing or communal services will not be enough. An individual must enter specific quantitative or qualitative characteristics into the act. For example, in this case, if the temperature of cold water is below the standards prescribed in the contract with the supplier, then you need to indicate how many degrees it is. In addition, the day, month and year from which the consumer noticed this deterioration is displayed, as well as the date when the supply of the utility service returned to normal.
About the compilers of the act. At the bottom of the document, there must be information containing information about the positions of the performer and consumer, as well as their addresses with contact numbers. Under the relevant data, each of the parties must put their signature. The surnames, names and patronymics of all other consumers who signed this act are also indicated, thereby confirming the inadequate quality of this utility service.

After the document is completed, do not forget to make a second copy of it. Moreover, each copy must be signed by both users of this utility service and individual acting as a supplier representative. After the submission of the act, the supplier is given exactly three days, during which he has the right to refuse to satisfy the requests set out in the document. If actions of this kind were not taken, then by default it is considered that the supplier agrees with all claims and undertakes to improve.

Often rendered poorly public Utilities and reluctantly eliminate various accidents in house communications. But this is their direct duty, prescribed in the rules approved by the government.

And if you are faced with violations of the norms and rules of service by the "communal services" - this must be dealt with. And we'll show you how. In this article, we will consider how to achieve the supply of high-quality and well-heated hot water to an apartment. After all, it has long been included in the list of necessary amenities for living.

The temperature of hot water in the apartment

Hot water is one of the most expensive items on your utility bill.

Its cost is formed from the price per unit volume of water spent, multiplied by the number of cubes spent. But this is the case when a hot water meter is installed in the dwelling.
And when it is not there, then the fee is calculated taking into account the consumption standard, the number of registered residents and the established tariff.

According to the standards enshrined in SanPin, the temperature supplied from the tap to residential buildings hot water at the point of reception should be kept in the range from 60 degrees Celsius to 75. The utilities do not have the right to exceed or lower this threshold. After all, we pay monthly for the provision of this service.

There are fixed rules tolerances from the given values. At night, which lasts from 00 to 05 hours, should not exceed five degrees. In the daytime - no more than three degrees up or down.

The State Housing Inspectorate and similar state organizations. They are obliged to respond to citizens' appeals and send inspection inspectors to the "communal workers" against whom the complaint was filed.

The following video will tell you in more detail about the temperature norms of hot water in the apartment and what to do if it does not meet such a norm:

And now is the time to find out what to do if the temperature of the hot water is below normal.

What if they are not followed?

So, what do you do if the hot water is low temperature?

Well, firstly, you need to use your right, prescribed in the Constitution of the Russian Federation, to appeal to government agencies. We write a statement about the commission administrative offense to the State Housing Inspectorate.

How to make a complaint

Let's figure out how to properly file a complaint:

in the right upper corner write where and from whom, indicating the address of registration and contact details;
in the header we write the word “statement”, and then the following text “on the commission of an administrative offense under Article 7.22 of the Code of Administrative Offenses “Violation of the rules for the maintenance and repair of residential buildings”;
then we turn to the text of the complaint itself in the form that at the address of such and such a housing department such and such does not comply with the norms of the Housing Code of the Russian Federation, indicating the main essence of the problem;
at the end, we write an appeal to the official of the GZhI with a request to organize a check of this fact, issue an order to eliminate and punish the perpetrators;
put your signature and date.

A good example of a statement indicating all legal regulations and acts, as well as its electronic submission form can be found on the RosZhKH website. In addition, you can download such an application.

Procedure

Now we will describe step by step how to act in case of a decrease in the temperature of hot water in your home:

we write an application to the State Housing Inspectorate (if the application is not only from you, but also from the neighbors, then the utilities will start working much faster);
we send it there, both in person and by registered mail;
We are waiting for a response from the official. By law, he must give it no later than thirty days from the date of receipt, plus the time for forwarding;
usually the time allocated for elimination is different, but on average it is one and a half months;
If the problem is not fixed within the agreed time, feel free to sue.

Poor quality water: what to do?

As well as in the case of the temperature of the hot water supplied to your home, the question of its quality is spelled out in SanPiN. It clearly states that hot water should be clean, without excess taste and bad smell. For this service, our hard-earned money is also held monthly. And, if the water still does not have the characteristics established by sanitary doctors, it is necessary to complain.

So, what to do and where to go if poor-quality water comes out of the tap?

You can fix the fact that such a liquid has been supplied to your home by calling the emergency service. The dispatcher without fail records your complaint in the call log, indicating the time, address and reason for the appeal. After that, ask him to tell you the registration number. If the reasons associated with the deterioration of water quality in your home are known to the specialist, he should inform you about them.
Within a couple of working days, an inspector from a resource-saving company and a representative of the housing department must come to you. They make a deed poor quality water according to the standard pattern.
If the engineer did not arrive within the specified time, call an employee of the house management company and any two neighbors, draw up this document in their presence, after which all those present sign it with a note that the inspector is absent. Such paper is considered valid. Based on the act, a statement is written.

The complaint scheme is identical to that discussed above for a complaint about improper hot water temperature. You also make an application to officials from the State Housing Inspectorate, guided by the same legal acts and terms of consideration. The only thing that will differ in your complaint is the reason for the complaint. You indicate it as "poor quality water" or "water of inadequate quality."

After following the entire procedure, we receive a response from the inspector and wait for the problem to be fixed. Remember, a collective complaint or accelerates the resolution of the resulting decline in water quality in a positive direction.

Competently and correctly drafted statement in electronic form search at the same email address, at RosZhKH. Or you can view and download it directly.

How did tenants make a complaint about non-compliance with hot water quality standards apartment building see the following video:

We require recalculation

There are rules for payment and provision of utilities, which are regulated by the Decree of the Government of the Russian Federation. They very competently and in detail cover all recalculations for utilities provided poorly.

So about hot water it says that it must be delivered uninterruptedly and be of the proper temperature and quality. with a shortage or excess (which happens much less often) of temperature is: a decrease of 0.1 percent of the base tariff per unit of volume for every 3 degrees. In the case when the heating of hot water is less than 40 degrees, it is paid at the rate of cold.

You can reduce the fee for the number of days or hours when low-quality hot water was supplied as follows:

we divide the number of days in which hot water was poured in inadequate quality by the number of days in a month;
The amount received is multiplied by the tariff rate.

The number that turned out and will be a discount for poor-quality utility services.

We hope that our advice will help you protect your rights against the “lawlessness of public utilities”. Never be afraid to do this - and you will always have all the necessary benefits of civilization in your house! After all, as it shows arbitrage practice regarding consumer claims for poor quality drinking water, make it all really possible!

The presence of a hot water supply system is a prerequisite for any modern comfortable housing. For this reason, it is important for every owner of residential real estate to know what temperature of hot water in the tap, according to the 2016 SNP standard, should be in the tap.

It should be noted that hot water supply plays the most important function for consumers. With its help, the likelihood of the formation of viruses and infections, the development of pandemics and epidemiological diseases is reduced. Also, hot water is a convenience that allows you to maintain cleanliness in the apartment and not experience discomfort while living in it.

Each person can measure the temperature of incoming water using a conventional thermometer. Therefore it is important to know normative indicators for hot water, approved by government regulations:

closed systems - from 50 degrees;
open systems - from 60 degrees;
joint systems - from 75 degrees.

Having figured out what temperature of hot water should be in the apartment according to the law, you can safely defend your rights before utilities. At the same time, it is important that there are no deviations in both directions: insufficient temperature will not kill harmful bacteria, and excessively heated water can cause a burn.

It should be noted that the temperature of hot water in apartment building in some cases may differ from the actual situation. Utilities have the right to reduce the temperature of the water supplied to the water supply for the following reasons:

emergencies that occur on the highway or pumping station;
failure of housing communications;
carrying out planned and preventive work.

These reasons can lead to a suspension in the supply of hot water. However, the current regulations also describe the length of the period for stopping the supply of water to apartment buildings:

up to 4 hours in a row;
up to 8 hours per month;
up to 24 hours in case of accidents.

In practice, utilities quite often allow violations of the established time. Homeowners themselves are not able to influence this situation, but they may require a recalculation of the tariff used for water heating. Economists have calculated that when hot water is turned off, the price should be reduced by 0.15%.

It will not be possible to immediately attract specialists to measure the temperature of water in a hot tap, since there is a clear verification algorithm. Only its observance will make it possible to draw up an act that will be recognized by public utilities and other authorities.

If the temperature of hot water in the apartment is not observed in 2016, then prove given fact can be done by following the steps below:

open the faucet with hot water for 2-3 minutes to drain the liquid that has stagnated in the pipes;
place a special glass under the jet to fill to a certain level;
immerse a thermometer in a glass to measure temperature regime up to 100 degrees;
record the results.

It must be borne in mind that a certain deviation is allowed in both directions from the standard temperature indicators:
