The situation when the hot water in the tap cannot reach the required temperature level is not that uncommon. And in order to understand that a problem exists, it is not at all necessary to measure the temperature of the water; it is enough to try taking a bath. Such an event will be more like hardening than a hygienic procedure. What should you do if the temperature hot water is clearly far from the norm, and where should a complaint be made in this situation.

According to approved documents, the standard temperature of hot water supplied to residential premises in apartment buildings must be no lower than 60 degrees.

The exception is at night, between 0.00 a.m. and 5.00 a.m., when a decrease in the established standard is allowed, but not more than 5 degrees. During the daytime, a temperature of at least 57 °C is acceptable.

What temperature standards for hot water are established according to SanPin?

The temperature of hot water according to SanPiN, according to resolution 2.1.4.2496-09, must comply with the following standard - the minimum value is 60 °C, and the maximum level corresponds to 75 degrees.

Small deviations are allowed within limits not exceeding five degrees at night and three during the day. Before approving such standards, experts should have taken into account the temperature at which unfavorable conditions are created for the life of harmful bacteria. Also, hot water should not cause burns. skin. Monitor whether this resolution is being implemented , The State Housing Inspectorate is authorized.

Utilities do not have the right to set their own temperature standards for water in residential premises.

If the standards do not comply, what hot water calculation coefficient applies?

Knowing the answer to the question of how many degrees hot water should be, you need to understand what calculation coefficient should apply if this norm broken

If it is discovered that the hot water supply is supplied in violation of the established temperature standards, payment must be recalculated. If the temperature does not reach 40 degrees, payment must be made at cost cold water.

The algorithm for calculating the coefficient if the norm indicator is violated is as follows:

Every three degrees below normal results in an hourly reduction in tariff by 0.1%.

Hot water is not up to standard where to complain

The main question that worries residents of apartment buildings if the hot water does not meet the standard is - Where to complain?

According to established rule, initially you need to call the housing and communal services or the management service. You should explain your situation to the dispatcher or service worker. Also, a similar action should be carried out, if there is no hot and cold water, you need to call the dispatch service. In this case, you must write down the time of application, the application number and the name of the dispatcher who accepted it.

If this was an emergency, then it must be eliminated, but if the reason for the decrease in temperature in the tap (at the water intake point) was not an accident, and the problem has not been solved, then you need to contact the utility service in person and set out your situation on paper. The application must indicate the measurement indicators at night and daytime, your passport details, address.

Next, the utility service, by prior agreement on the time, should provide a free service of measuring the temperature of hot water. After which, an act is drawn up based on the data received, and a decision is made on the need for recalculation. One of the copies of the act must mandatory handed over to the owner of the premises.

Measurements are made according to installed system. For this purpose, the water is drained within 3-5 minutes.

How to file a complaint

You can make a complaint on a printed form or write it by hand. It must contain the following information:

• Details of the person filing the complaint – full name, address. Usually located in the corner of the sheet on the right side
• Name of the organization to which the complaint is being made
• Briefly describe the essence of the problem
• Make a link to regulatory documents
• Indicate the inaction of the organizations to which the applications were sent, if any.
• List the documents attached to the application
• Sign and date

The complaint is submitted to the housing and communal services or the Criminal Code, and if a written refusal is received from them, the application is submitted to the court, the prosecutor's office or Rospotrebnadzor.

How to request a recalculation

In order for a recalculation to be made, you must file a claim with the housing and communal services. A copy of the temperature measurement report must be attached to the application. You can draw up such an act yourself by inviting neighbors as witnesses.

Also attached to the application is information about contacting the emergency service or the housing and communal services control room - date of application, application number and reason for application. It is possible to draw up a collective appeal from the residents of the house.

If the recalculation is not made, you should contact district court or to the prosecutor's office.

When fighting for your rights, you should remember the main thing - non-compliance with hot water standards in the tap not only causes inconvenience, but is also a serious offense on the part of the housing and communal services. Hot water supply and heating must be constantly monitored.

What are the requirements for hot water? On what indicators does the quality of hot water supply depend? Regulatory documents regulating the characteristics of the hot water environment in our homes. Main standards for hot water supply. Requirements for hot water in public institutions. Basic indicators of hot water, their maximum permissible values. Requirements for hot water are specified by the current GOST 2874-82. The quality of hot water supply must meet hygienic standards for drinking water supply.

Basic hot water standards

Although it is not recommended to drink hot water, but only use it for household needs, the requirements for it are the same as for drinking water supply systems. After heating, the water must meet the sanitary and hygienic requirements of water consumption. At the same time, very strict requirements are imposed on the temperature of such water. Both the 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 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.

At the same time, regulatory documents also regulate temperature requirements in places of water consumption. These requirements for hot water supply are specified in SanPiN 2.04.01-85. The following temperature values ​​are indicated:

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

Requirements for hot water in public institutions

1. As for the hot water that is supplied to the taps of washstands and showers in the buildings of organizations social purpose, as well as in kindergartens, schools and other institutions intended for children, the temperature of the hot water environment cannot exceed 37 degrees. The same applies to all medical institutions.
2. If all of the above organizations and institutions require the use of hot water at 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 feeding children and adults. This requires washing dirty dishes, and for this you need to use water with a temperature of 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. The production of drinking water in the place where water is heated or where this liquid is consumed is strictly prohibited.

Since heating the water increases the likelihood of scale deposits inner surface pipelines, as well as the rate of corrosion processes, water for hot centralized water supply must meet the following requirements:

• The oxygen content dissolved in the liquid must be within 0.1 mg/l.
• The concentration of suspended impurities is allowed to be no more than 5 mg/l of liquid.
• Temporary water hardness should be normal 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 oxidability of the aquatic environment is allowed to be 6 mg/l.
• Normally, free particles of carbon dioxide should not be found in such water.

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

If you would like to test the quality of your hot water supply, you can order this analysis from our independent licensed laboratory. We have passed state accreditation, so all test results will have legal force. The cost of the analysis depends on the number of monitored indicators and is specified when ordering a test by phone.

Standard hot water temperature in the apartment: optimal performance and features of recalculation

Standard hot water temperature in an apartment: optimal indicators and features of recalculation

No one else for a minute can't imagine life no hot water. Her shutdown V summer season for the time of traditional repair work- practically catastrophe for the residents who are so used to it.

Important to know that hot water is a concept clearly defined and established laws. It should not be a little hotter or a little colder, since its temperature officially defined.

Standards for hot water

Temperature hot water regulated standards SanPiN(Sanitary and epidemiological rules and regulations) 2.1.4.2496−09 , which were accepted into 2009 and have legal force in the present 2015. Legislators paid great attention to regulating this issue and highlighted it in separate document.

According to the rules, prescribed in that document, temperature hot water that flows from the tap must be within the limits from + 60 to +75 °С. These restrictions are related not only to compliance directly temperature regime in order to ensure hot water residents.

This temperature unfavorable For reproduction pathogens of infectious diseases. Maintaining this temperature Necessarily in all places of water intake.

Important to know: deviation from the standards at night by no more than 5°C, and during the day - by no more than 3°C, is considered acceptable. Night time is considered to be the time from 00.00 to 05.00. Daytime - from 05.00 to 00.00 hours.

How to measure water temperature?

To be sure approve that the temperature of the tap water does not correspond norms fixed in the law, it is necessary measure. Step by step instructions Self-measuring hot water temperature is as follows:

1. Open the tap hot water;
2. Let the water drain(about 5 minutes);
3. Take capacity, volume containing meter;
4. Send a stream of water from the tap into the container so that the water constantly flows out;
5. Lower the thermometer to the center of the container to the required depth;
6. Compare the readings obtained thermometer with standard.

If the recorded temperature reading is significantly below normal, need to:

• Contact the organization responsible for the water supply in the house with statement about unacceptably low temperatures;
• Take a water measurement in the presence of a representative of the organization;
• Commit detected violations in the form of an act.

This is important: The water measurement report must contain temperature readings obtained during the procedure, no later.

Based on the act is adopted solution about fee recalculation by hot water. Instances Both the resident and the company serving him must have the document.

If violations identified and recorded responsible organization obliged eliminate the cause of the discrepancy and make recalculation for hot water.

Fixed temperature value at 40°C provides grounds for recalculating fees for hot water according to tariffs cold

The danger of non-compliance with hot water supply standards

Regulation hot water supply - vital necessity. Non-compliance the temperature regime of hot water used in residential premises threatens serious consequences:

• • Bacteria reproduction. At low temperatures of hot water, the risk increases active reproduction of dangerous bacteria and their entry through water into the human body. Norms hot water temperatures selected not by chance- this is an indicator at which pathogenic bacteria that cause For example, pneumonia, die within 2 minutes. Moreover, this temperature doesn't allow bacteria can multiply, as the environment is unfavorable for them;

• Burn. Bacteria die instantly and do not reproduce at all in very hot water - from 80°C and above. However, water at this temperature - not suitable for use. Moreover, she can become reason serious burn. For human safety reasons, the standard level of hot water (from 60 to 70°C) must not be exceeded.

Do you need a water heater?

In apartment buildings direct need to install a water heater No. Hot water is no longer a luxury, but a common condition of normal life. However, for particularly heat-loving residents there is indirect reasons to its installation. Namely:

• • Reluctance stay no hot water in summer. During the planned annual shutdown of hot water or during repairs of the water supply system, it will solve the problem. If other residents are forced to heat water, say, gas stove, water heater owners release yourself from such a duty;

• Reluctance remain without hot water even on short term . Due to accidents in the apartments of other residents and while they are being eliminated, hot water is usually turn off. If an hour or a day without hot water is a big problem, buying a water heater is great solution its elimination.

Qualitative a water heater is necessary in private houses where the hot water supply is originally absent. This device is significantly will simplify life of the inhabitants of the house, will deliver them from the need to constantly heat the water.

So if interruptions with hot water or its constant absence in the house - your everyday life, . Impressive volume storage tank modern models heaters ( up to 150 liters) will allow you not to save on hot water.

In addition, water from taps and wells, which often used residents of private houses can represent danger for human health - it may contain harmful viruses and bacteria. Before use well water, it is recommended to carry it out cleaning or just boil it.

It's possible that without a water heater the water temperature suitable for disinfection will not be reached. When heating “manually” it is difficult to control the temperature, and the water heater guarantees sufficient heating of the water.

Water supply is certain measures and activities aimed at providing the population, enterprises, various types farms with water for industrial, domestic and drinking needs. Supplying people with hot water is one of the main components of a comfortable everyday life. The choice of liquid supply depends on why hot water is needed: central, or through local water heaters.

IN centralized system The water is heated using columns or hydraulic devices. For individual supply of hot water, coils, tanks and other welded containers are used.

Requirements for hot water supply according to SNiP

Building codes that deal with hot water temperatures in buildings are taken from regulatory documents regulating the order of various buildings and structures. This document specifies the supply mode, the temperature of hot water according to SNiP, the operation of boiler rooms, the water supply system and other standards.

According to these standards, the pressure in hot water supply should not exceed 0.6 MPa. The temperature of hot water according to SNiP at water intake points must comply with the following standards:

• More than 60 degrees – for central water supply systems connected to open views heat supply systems;
• More than 50 degrees – for central water supply systems connected to closed systems heat supply;
• But less than 75 degrees – for absolutely all hot water supply systems.

Water, the temperature of which ranges from 50 to 75 degrees Celsius, can easily wash off fats and disinfect detergents, but supplying water at such a temperature does not make it possible to get burned when the liquid comes into contact with human skin.

Hot water is supplied to the home from the boiler room, where it is pumped by a water pump. Heated in the boiler, the water is released through central pipes to the consumer. The hot water temperature according to SNiP is from 50 to 75 degrees, the same is supplied for use daily hygiene. And a person can regulate the temperature himself by diluting it with cold water.

Types of water heaters

There are differences in heaters in power, power supply and structure. Of course, if you need hot water supply, in accordance with SNiP standards, then it is better to take a responsible approach to purchasing a water heater. When choosing water heaters, you need to know their two categories:

• Flow-through;
• Cumulative.

Flow-through devices heat the liquid, but do not have a reserve. To quickly heat the liquid every time, you need large number energy. And this heater must work instantly; when turned on, the temperature of the hot water according to SNiP will correspond to the established rules.

Hot water supply according to SNiP using a gas water heater is the most understandable example of these heaters.

Storage water heaters slowly heat up the required volume, but they consume only 2 kW per hour. A person can consume liquid when he needs. When the valve turns, hot water flows out instantly. But there is also a disadvantage to this type of heater - it is large sizes. The volume of liquid held depends on the size of the water heater. Most often, the diameter does not exceed 50 cm, and increasing the volume, the height of the tank increases. The boiler, which holds 50 liters, is 60 cm in height.

In any heater, you can determine the temperature using a thermometer; it is located on the visible side of the device. The hot water temperature according to SNiP strictly corresponds to the degrees on the water heater display.

How much water supply is needed

The hot water supply of SNiP depends on many nuances, including the richness of life and the number of people living in the building. It doesn’t matter what kind of building, be it a house or an apartment, hot water supply starts in a short time.

According to existing rules and the standards are given 11 minutes for a full launch. To put it simply, after 11 minutes, hot water must be available to people in a certain quantity and can be used at several points at the same time.

Water supply calculations must be made taking into account such features of the lives of living people as:

• Number of people;
• Number of bathrooms using hot water;
• Capacity of plumbing elements (volume of the bathroom, etc.);
• Hot water at what temperature is expected by residents.

Just 20 years ago, people could not dream of hot water supply to private homes, especially outside the city. And in present moment this is quite realistic and even economical.
