Hot water supply temperature. The norm of the temperature of hot water in the apartment: optimal indicators and features of the recalculation

According to sanitary standards, hot water from the tap should be from 60 to 75 * C. If the water temperature is less than 60 * C, then you need to require recalculation.

17.03.2011 I call the control room with the requirement to measure the temperature of the water. According to the government decree of 05/06/2011 N354 "On the provision of communications services to owners and users", the procedure should be as follows:

106. A report on a violation of the quality of a public service can be made by the consumer in writing or orally (including by telephone) and is subject to mandatory registration by the emergency dispatch service. In this case, the consumer is obliged to report his last name, first name and patronymic, the exact address of the premises where a violation of the quality of the utility service was found and the type of such utility service. An employee of the emergency dispatch service is obliged to inform the consumer of information about the person who received the consumer's message (last name, first name and patronymic), the number for which the consumer's message is registered, and the time of its registration.

107. In the event that an employee of the emergency dispatch service of the contractor knows the reasons for the violation of the quality of the utility service, he is obliged to immediately inform the consumer who has applied and make an appropriate note in the message log.

108. If the employee of the emergency dispatch service of the contractor does not know the reasons for the violation of the quality of the utility service, he is obliged to agree with the consumer on the date and time of checking the fact of violation of the quality of the utility service.

109. At the end of the audit, an audit report is drawn up. [...] The verification act is drawn up in the number of copies according to the number of interested persons participating in the verification, signed by such persons (their representatives), 1 copy of the act is transferred to the consumer (or his representative), the second copy remains with the contractor, the remaining copies are transferred to the interested parties participating in the test.

In fact, it turns out that ZhEU-54 does not have such a practice. For example, there is no suitable form:

Complaint about the refusal to recalculate the payment for hot water.

On March 17, 2011, at my request, due to the low temperature of the hot water supply, the chief engineer of ZhEU-54 LLC Khairetdinova Kh.Kh. the temperature of hot water in the bathroom and in the kitchen was measured.

After a 5-minute drain of hot water, the temperature of the pipes was measured. Since in the bathroom the hot water in the faucet comes from the pipe of the heated towel rail, the temperature in the act is indicated as "return temperature (p \ dry): 40.5 * C". Measurements of hot water in the kitchen in the act are indicated as "DHW temperature at the supply: 50 * C".

Provided for by paragraph 74 of Decree of the Government of the Russian Federation of 23.05.2006 N 307 "On the procedure for providing public services to citizens", a repeated temperature measurement was made only on April 12. The hot water temperature in the bathroom was 44*C.

To my request to recalculate the payment for hot water supply, I received a response dated April 11, 2011 No. 766 with the following content: "according to the act, the temperature of the hot water supply is 50 * C, the temperature in the bathroom was not measured. The temperature of the hot water supply corresponds to the standard values, the recalculation is not performed." Thus, among other things, there is a discrepancy in the answer with the fact that the temperature of the hot water in the bathroom was measured and was equal to 40.5 * C

I did not agree with this decision and on April 19 sent a second request, in which I demanded a recalculation in accordance with paragraph 6 of Appendix No. 1 of Rules 307. In the answer of 04.25.2011 No. 864, all my arguments were ignored and again there was only a reference to paragraph 5 of Appendix No. 1 of Rule 307.

I insist that the recalculation should be made in accordance with paragraph 6 of Appendix No. 1 of Rules 307, since there is a violation of sanitary standards and the presence of paragraph 5 of Appendix No. 1 of Rules 307 does not mean that the management company has the right to violate sanitary standards.

So, according to SanPiN 2.1.4.2496-09:
1.2 Real sanitary regulations are binding on all legal entities, individual entrepreneurs whose activities are related to the organization and (or) provision of centralized hot water supply systems.
2.4. The temperature of hot water at the draw-off points, regardless of the heat supply system used, must not be lower than 60 °C and not higher than 75 °C.

According to paragraph 6 of Appendix No. 1 of the Rules "On the procedure for providing public services to citizens", approved by Decree of the Government of the Russian Federation of 05.23.2006 N 307, one of the requirements for the quality of public services in terms of hot water supply is the constant compliance of the composition and properties of hot water sanitary standards and rules.

The fact that such an indicator as water temperature refers to the properties of water follows from the interpretation in the aggregate of the provisions of SanPiN 2.1.4.2496-09 (in particular, paragraph 2.1.) And Rules 307 (paragraph 6 of Appendix No. 1).

According to paragraph 6 of Appendix No. 1 of Rules 307, it is stipulated that deviation of the composition and properties of hot water from sanitary norms and rules is not allowed, if the composition and properties of water do not comply with sanitary norms and rules, payment is not made for each day the provision of communal services of inadequate quality (regardless of indications metering devices).

In addition, the requirement of SanPiN 2.1.4.2496-09 to maintain a hot water temperature of at least 60 * C does not contradict, but only tightens the requirement of paragraph 5 of Appendix No. 1 of Rule 307, according to which the temperature of hot water must be at least 50 * C for closed systems district heating.

ASK:
1) bring OAO "UZHKH Kalininsky district of the urban district of Ufa RB" to administrative responsibility under Part 2 of Art. 14.4 of the Code of Administrative Offenses and Art. 6.4 Administrative Code
2) issue an order to recalculate the payment for hot water supply for March in accordance with paragraph 6 of Appendix No. 1 of Rule 307, considering the period for the provision of utilities of inadequate quality from March 17, 10:00 to March 31, 24:00
3) due to the fact that the answer to my request dated April 19 was issued only on April 25, I ask you to warn OJSC UZHKh of the Kalininsky district of the urban district of Ufa of the Republic of Belarus about the inadmissibility of violating the requirements of paragraph 49, subparagraph "I" of rules 307, according to to whom a notice of acceptance of this requirement and subsequent satisfaction or refusal to satisfy it, indicating the reasons for the refusal, must be sent to the applicant within two working days, otherwise it is possible to initiate an administrative case under Part 1 of Article 14.8 of the Code of Administrative Offenses
4) due to the fact that SanPiN 2.1.4.2496-09 does not provide for standards according to which a deviation in the water temperature during the first minutes would be allowed, please explain to ZhEU-54 LLC that the water temperature should be measured without first draining the water. *

* Later it turned out that a three-minute water drain is still provided for measuring the water temperature

10.05.2011 a whole delegation arrives to measure the water temperature: a representative of Rospotrebnadzor, an employee of the Center for Hygiene and Epidemiology in the Republic of Belarus, Chief Engineer ZhEU-54, two important representatives of "Kalinin UZHKh".

23.05.2011 comes the answer from Rospotrebnadzor:


1.06.2011 UZHKh announces:

Receipt arrives:

16.06.2011 just in case, I am writing a statement with a request to explain exactly how the recalculation was calculated:

In accordance with paragraph 49 (subparagraph "p") of the Decree of the Government of the Russian Federation "on the procedure for the provision of public services to citizens" dated May 23, 2006 N 307, I PLEASE, no later than 3 working days, provide documents confirming the correctness of the recalculation of fees for hot water supply in receipts for payment for June 2011

21.06.2011 UZHH sends a letter to the ERCC:

21.06.2011 ERCC issues a certificate. The text is hard to read, but the bottom line is that the size of the return was calculated by the formula: (<Тариф горячей воды> - <Тариф cold water>) * <Объём горячей воды> * (<количество дней с температурой ниже 60 *С> / <количестве дней в месяце>)

The norm of the temperature of hot water in the apartment: optimal indicators and features of the recalculation

The norm of the temperature of hot water in the apartment: optimal indicators and features of the recalculation

no one already and for a minute can't imagine life without hot water. Her shutdown V summer season at the time of traditional repair work- practically catastrophe for residents who are so accustomed to it.

It is 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, as its temperature officially defined.

hot water regulations

Temperature hot water regulated norms SanPiN(Sanitary and epidemiological rules and norms) 2.1.4.2496−09 which were accepted in 2009 and have legal force in this 2015. Legislators paid great attention to the regulation of this issue and singled it out in separate document.

According to the rules prescribed in that document, the temperature hot water that flows from the tap must be within from + 60 to +75 °С. These restrictions associated not only with the direct observance of the temperature regime in order to ensure hot water tenants.

Such a temperature unfavorable For breeding pathogens infectious diseases. Maintaining this temperature Necessarily in all places of water intake.

It is 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 from 00.00 to 05.00. Daytime - from 05.00 to 00.00 hours.

How to measure water temperature?

To accurately approve that the temperature of the water at the tap does not match the norms fixed in the law, it is necessary to measure. step by step instruction self-measuring hot water temperature is as follows:

1. open faucet hot water;
2. Let the water drain(approximately 5 minutes);
3. Take capacity, the volume containing the measuring device;
4. Send a stream of water from a tap into a container so that water constantly flows out;
5. Lower the thermometer in the center of the tank to the required depth;
6. Compare received readings thermometer with normative.

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

• Contact the organization responsible for the supply of water in the house with statement about unacceptably low indicators of its temperature;
• Perform a water test in the presence of a representative of the organization;
• Fix identified violations in the form of an act.

It is important: the act of measuring water must contain temperature readings obtained precisely during the procedure, no later.

Based act is adopted solution about recalculation of fees By hot water. Instances Both the tenant and the company serving him must have the document.

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

fixed temperature value at 40°С gives grounds for recalculation of payment for hot water according to tariffs cold

Danger of non-compliance with hot water standards

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

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

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

Is a water heater necessary?

In apartment buildings straight the need to install a water heater No. Hot water is no longer a luxury, but a familiar condition for a normal life. However, for especially heat-loving residents there are indirect reasons to install it. Namely:

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

• reluctance stay without hot water on short term . Due to accidents in the apartments of other residents and for the duration of their elimination, hot water is usually turn off. If an hour or a day without hot water - a big problem, buying a water heater is the perfect solution to eliminate it.

Qualitative water heater is required private houses, where hot water supply was originally absent. This device is very will simplify life of the inhabitants of the house, save them from the need to constantly heat the water.

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

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

It is 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 warm water.

This temperature is measured directly at an open tap by immersing a water thermometer in a glass under a jet to a special mark. In accordance with Appendix No. 1 to the Rules, hot water supply must be uninterrupted and around the clock throughout the year. Permissible duration of a break in the supply of hot water: 8 hours (in total) within 1 month, 4 hours at a time, in case of an accident on a dead end line - 24 hours in a row; the duration of a break in hot water supply in connection with the production of annual repair and maintenance work in centralized networks of engineering and technical support for hot water supply is carried out in accordance with the requirements of the legislation of the Russian Federation on technical regulation (SanPiN 2.1.4.2496-09).

The temperature of hot water in an apartment building

But if the indicator is set above 55 degrees, then there is a risk of getting burned. Because of this, hot water is used along with cold water. The temperature standard for hot water in an apartment in winter does not differ from the established indicator.

Residents should be in control. If this does not meet the standards, then it is important to contact the competent authorities in a timely manner to resolve the issue. A temperature above 75 degrees leads to breakdown plastic section plumbing, which is in many modern apartments. Deviation includes even a slight increase or decrease in performance.

Attention

There must be a minimum, even if communications and heating equipment old. The standard for the temperature of hot water in the apartment is indicated in the contract concluded between the client and the service provider. Why is it important to follow temperature regime? Temperature control is an important necessity.

What is the hot water temperature in the apartment?

We analyze this situation - we take the entrance floor and check this situation in the apartments on this floor. For example, we have four apartments - in three everything is fine, and in the fourth apartment this situation occurs. To confirm our assumptions, we check the apartments on the floor above or below in the same way, no difference.

The situation is 100% repeated - you can not check further. You are dealing with unauthorized re-equipment of engineering communications related to common house property. From practice, there are cases when in a 17-storey building, residents arranged such a re-equipment in 16 vertically adjacent apartments, which led to a complete absence of hot water circulation in the system and, as a result, the residents of this building bombarded the supervising authorities with complaints about poor-quality public services .
This situation originated from ignorance by a resident of the boundaries of the division of property, i.e.

Hot water temperature standard - what to do if it does not meet the standards

The complaint should be written in almost the same way as for temperature. It is necessary to write an application for the head of the housing inspectorate, indicating the regulatory legal acts and the time for consideration of the document. Only as the reason it is necessary to designate "poor-quality water".

Important

After that, a response from the inspector should come, and you can wait for the solution to the problem. A collective application significantly speeds up the review procedure, so the water quality will soon be restored. Drawing up a complaint In case of violation of consumer rights, a claim is drawn up.

It is necessary to write it in a generally accepted way, in a neat and legible handwriting. It is important to indicate to whom the application is intended. Usually the document is drawn up for the head management company which is a water supplier. Be sure to indicate all the facts: calls, appeals to employees with applications, visits to the management company.

The exception is at night, in the interval between 0.00 and 5.00, when a decrease in the established standard is allowed, but not more than 5 degrees. In the daytime, an indicator of at least 57 ° C is permissible. What temperature standards for hot water are established according to SanPin Do you need help? Consult with our lawyer for free!

The temperature of hot water according to SanPiN, according to Decree 2.1.4.2496-09, must comply with the following standard - the minimum indicator is at around 60 ° C, and the maximum level corresponds to 75 degrees. Small deviations are allowed within the limits not exceeding five degrees at night and three during the day.

The norm of the temperature of hot water in the tap in the apartment, sanpin

If the deadlines have been extended, then a recalculation of the payment for services is required. A reduction of 0.15% is required. Checking the norm Utilities must necessarily comply with the standard for the temperature of hot water in the apartment. General position document includes rules for checking compliance.

Residents need to be able to check the water temperature. If there are deviations, then you need to file a claim. The water test procedure includes the following steps:

• you need to open the tap, and let the water drain for about 2-3 minutes, during which time the cooled liquid will be eliminated;
• then you need to pour water into a special glass;
• a sensitive thermometer with a scale of 100 degrees must be immersed in the container;
• you should wait for the thermometer to heat up, after which the readings are recorded.

Although the temperature standard is in a wide range, there may be some deviations.

Hot water temperature: what should it be?

This indicator is characterized by a minimum (not lower than 60 °C) and a maximum limit (not higher than 75 °C) and does not allow deviations from the specified temperature regime, under which the quality of public services is ensured.” The temperature of hot water at the points of water intake, regardless of the heat supply system used, should not be lower than 60 C and not higher than 75 C. GROUNDS: clause 5.1.2 of SP 30.13330.2012 "Internal water supply and sewerage of buildings" Updated version of SNiP 2.04.01-85 * ; clause 2.4 SANPiN 2.1.4.2496-09 "Hygienic requirements for ensuring the safety of hot water supply systems"; 5.3.1 "Rules and regulations technical operation housing stock” (approved by the Decree of the Gosstroy of the Russian Federation of September 27, 2003 No. 170); clause 5 of Appendix 1 "Rules for the provision of public services to owners and users of premises in apartment buildings and residential buildings" (approved by Post.

About standards for air and hot water temperatures in apartments

From the same schedule depends on how much the risers and radiators of the heating system will heat up. For example, at -5 °C atmospheric air the temperature of the coolant in the riser must be at least 78 degrees. However, what to do if hot water supply in apartment building does not correspond to the norm? You need to file a claim (application) with the Housing and Communal Services or the Management Company that services the house.
Temperature measurements: a sample act The Management Company, most likely, will not pay attention to an unfounded complaint. Therefore, you need to arm yourself with facts and measure the temperature of hot water in your MKD yourself using a special sensor with a built-in regulator.

Info

Before approving such norms, experts had to take into account at what temperature unfavorable conditions are created for the vital activity of harmful bacteria. Also, hot water should not cause burns. skin. The State Housing Inspectorate is authorized to control whether this resolution is being implemented.

Public utilities are not entitled to establish their own temperature norms water in residential areas. If the norms do not comply, what coefficient for calculating hot water is valid Knowing the answer to the question of how many degrees hot water should be, it is necessary to understand what coefficient for calculating should act if this norm is violated. If it is found that hot water supply is supplied in violation of the established temperature standards, a recalculation of the payment must be made.

No more than 8 hours at a time at a room temperature of 10 to 12 degrees, no more than 4 hours at a room temperature of 8 to 10 degrees. For each hour that exceeds the specified standards, the monthly heating fee is reduced by 0.15%. Hot water temperature In accordance with clause 5.1.1, the quality of cold and hot water (sanitary and epidemiological indicators) supplied for household and drinking needs must comply with SanPiN 2.1.4.1074 and SanPiN 2.1.4.2496.

The temperature of hot water in the places of water intake must comply with the requirements of SanPiN 2.1.4.1074 and SanPiN 2.1.4.2496 and, regardless of the heat supply system used, must not be lower than 60 ° C and not higher than 75 ° C.

What should be the temperature of hot water at the entrance to an apartment building

There is an interesting document: “DESOLUTION OF THE SUPREME COURT OF THE RUSSIAN FEDERATION FROM MAY 31, 2013 N AKPI13-394”, which, among other things, establishes: “SanPiN 2.1.4.2496-09, as follows from the content of its paragraphs 1.1 and 1.2, establishes hygienic requirements for quality water and organization of centralized hot water supply systems (hereinafter referred to as STsGV), as well as the rules for monitoring the quality of water supplied by STsGV, regardless of departmental affiliation and ownership, and is mandatory for all legal entities, individual entrepreneurs whose activities are related to the organization and ( or) provision of centralized hot water supply systems. According to the specified SanPiN, the temperature of hot water at the points of draw-off, regardless of the heat supply system used, must not be lower than 60 ° C and not higher than 75 ° C.

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 requested services. This is especially acute in the summer season. planned water shutdown, but it lasts a short period.

Dear readers! Our articles talk about typical ways legal issues, but each case is unique.

If you want to know how to solve exactly your problem - contact the online consultant form on the right or call free consultation:

What if during the year from the tap instead of hot water arrives slightly warm? And what temperature should the tap water be? apartment building? We will talk about the standards for the temperature of hot water in the apartment below.

What is the service life of a gas meter according to the law, and what to do if it is overdue? find out right now.

What should be the quality?

What do SNIPs, GOSTs and SanPins say? In accordance with the Decree of the Sanitary and Epidemiological Service (SanPiN 2.1.4.2496-09 paragraph 2.4) certain rules have been introduced on the temperature mode of delivery of water to residential premises.

This document indicates the temperature limits for water supplied to apartments. They range from 60°С to 75°С.

It is this range that was not chosen in vain. 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°С the risk of growth of infectious agents, such as legionella, increases in a warm environment. At 70°C-80°C, complete disinfection occurs. An indicator of 40 ° C contributes the best breeding this bacterium.

In the SanPiN Resolution, paragraph 2.2, it is written that the water supplied to residential buildings must be of high quality: without bad smell without any aftertaste.

Must comply compliance with sanitary and epidemiological standards. In case of violations, organizations supplying utilities need to establish the cause of the supply and eliminate it.

Permissible deviation at the draw-off point

Government Decree No. 354 adopted allowable norms deviations in the temperature regime of 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 norm 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 of cold water. But for this it is necessary to have an official measurement certificate confirming the deviation from the norms.

How to write a complaint?

At repeated violation the temperature regime for the supply of hot water should be supplied to utilities.

It is important that this document is written correctly and 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 whom the complaint is directed.

The heading of the complaint is written:

1. Statement of Violation of Regulations providing the population utilities in accordance with Federal Law No. 195 article 7.23
2. The text of the statement states crux of the problem. It is obligatory to mention the measurement carried out and information from the drawn up act is entered: the date of the measurement, the name of the employee who carried out the measurement, the water temperature.
3. At the end of the text of the complaint, a requirement is written to eliminate the causes that cause failures in the supply of hot water. It is worth pointing out the need to inform the applicant about the work carried out.
4. The document ends with the indication of the date of its compilation and the signature of the applicant.

It is important to set a period for which recalculation is to be made.

The beginning of the period is considered the date specified in the official act, and the end should be the date when final check done after eliminating the reasons for the supply of water that does not meet temperature standards.

In case of refusal to recalculate, you should either apply to the court.

In cases of violations in accordance with Federal Law No. 195, article 7.23, persons those responsible may be subject to penalties.: for officials, the amount of the fine will be from 500 to 1,000 rubles, for an organization - from 5,000 rubles to 10,000 rubles.

When paying for utilities, any user wants to receive for their money quality product. That is why you should not give up if a little warm water.

Knowing the hot water temperature standards, you can try to affect the services providing utilities: take measurements, draw up an act, recalculate, file a complaint with a higher authority.

On the provision of utility services for hot water supply of inadequate quality and a reduction in fees for hot water.

You can learn about how management companies cash in on the supply of hot water at insufficiently high temperatures from the video:

Hot water is the same integral part of our comfort as electricity, gas, heating. According to the level of needs, it can be put on a par with satisfying hunger and thirst.

If we turn to the Rules for the provision of public services, then in accordance with sanitary regulations and norms under the legislation of Russia (SanPiN 2.1.4.249 6-09), the permissible limits for the temperature of hot water should be from 60 to 75 degrees.

So, 65 to 75 degrees. These are the values ​​you need to focus on.

The same document reports the permissible deviation rates at the water intake point:

• if we are talking about night time (from 0:00 to 5:00), then tolerance no more than 5 degrees;
• if it is a day (from 5:00 am to 0:00 am), then the deviation should not exceed 3 degrees.

Recalculation in case of temperature non-compliance with standards

If the hot water temperature at the time of sampling was only 40 degrees, then payment for its consumption must be made according to the tariff for cold water. In order for the recalculation to be carried out, it is necessary to make temperature measurements water.

For starters, you should contact the dispatch service of the management company or housing and communal services. Mandatory application fixation about the water temperature below the prescribed one in writing, indicating the number of the application, the time of its acceptance and the name of the dispatcher. It is possible that the drop in water temperature was due to technical failure pipeline or for any other known reason. In this case, the dispatcher is obliged to notify about the emergency mode and the timing of troubleshooting.

If the temperature of the supplied hot water is reduced for unknown reasons, it is necessary to agree on the day and hour taking measurements. Further, after the measurements, an act is drawn up. Number of copies this document should be equal to the number of participants in the procedure. Based on the measurements taken, whether or not payment recalculation hot water at the rate of cold.

Features of measurements

1. Drainage of water should be carried out for at least two to three minutes.
2. It is worth paying attention to where the hot water comes from (for example, from a heated towel rail pipe or from an “independent” pipe).

It is also necessary to eliminate the inconsistency with SanPiN, for this there is an article 7.23 in the Code of Administrative Offenses, it sounds “Violation of standards for the provision of public services” and involves a fine.

Why is this temperature

I would like to understand why the norms of hot water for a residential building 60 - 75 degrees? When developing standards temperature supply hot water, the main points are the reproduction of bacteria and the likelihood of burns. That is temperature run must be such that harmful bacteria are killed, but at the same time, that the water consumed does not lead to burn injuries. The latter is very important for children's or medical institutions.

Fresh and warm water is a great place for breeding and habitat such a dangerous bacterium as "legionella". This bacterium is very dangerous and can multiply in heating, air conditioning and humidification systems.

For example, in 2007 in Verkhnyaya Pyshma, more than 160 citizens, 5 deaths were recorded.

If we consider the temperature regime of water, then the effect on deadly bacteria following:

• 70−80°С: at this temperature, the disinfection process takes place;
• 66°C: legionella dies within 2 minutes;
• 60°C: bacteria die in 22 minutes;
• 55°C: the bacterium is destroyed in 5-6 hours;
• 20−45°С: temperature of active reproduction of bacteria;
• below 20C, the bacterium does not multiply.

It would seem that the conclusion is obvious: it is worth supplying hot water with high temperature heating. But there exists back side. If the temperature of the tap water over 50 degrees there is a chance of getting burned. Water temperature over 65 °C - skin burn in 2 seconds, temperature 65 °C - epidermis burn in 5 seconds, water temperature 55 °C - skin burn in 90 seconds.

Thus, the temperature in the reserve storages for heating and supplying hot water must be very high. But its use is possible only together with the simultaneous supply of cold water.
