DHW measurements. What temperature of hot water should be in the apartment

SanPiN regulations strictly establish what the temperature should be hot water in an apartment - the standard of 2019 remained unchanged compared to the previous year. This means that all citizens of Russia have the right to use hot water a certain temperature (for which, by the way, they pay) and complain when they encounter violations of SanPiN requirements. And the point is not at all that along with water, a citizen is deprived of basic amenities - if the water flowing from the tap is too cold or too hot, the health of the person who uses it is at risk.

What standards have been set?

What temperature should hot water be? It directly depends on the type of water supply system:

If the system is open minimum 60 degrees Celsius.

IN closed system – minimum 50 degrees Celsius.

According to the regulations of 2019, the temperature of hot water in the apartment should not exceed 75 degrees. This limit does not depend on the type of water supply system.

The temperature regime is extremely important to observe for a number of reasons.

If the temperature is too low, the fluid becomes contaminated with pathogens and bacteria. At the set minimum temperature threshold, harmful bacteria are doomed to death.

Too hot water can cause skin damage (burns). Strictly speaking, even at 55 degrees there is a risk of burns - therefore, citizens connected to open water supply systems are advised to “mix” cold water with hot water.

Exceeding the temperature threshold leads to damage plastic elements plumbing - and in fact in most modern apartments plumbing is mostly plastic. Who should pay for repairs in this case is a big question. All the time while the citizen will look for the guilty and prove the right to compensation, he will have to sit unwashed.

A drop in temperature to 59 degrees or an increase to 76 in open system water supply is already considered a violation of the Rules for the provision utilities(there are some). However, these Rules still allow minor deviations from the temperature limits.

It is allowed to lower the temperature during the day (from 5 am to midnight) by 3 ° Celsius - that is, up to 57 °.

At night (from midnight to 5 am), it is permissible to lower the minimum threshold by 5 ° - that is, up to 55 °.

The supply of hot water can be completely suspended in 2 cases: if on pumping station or the supply line has an accident, or if scheduled maintenance work is being carried out. In the case of prevention, citizens are not entitled to deprive water supply for more than 4 hours.

How to measure temperature?

Of course, it is useless to go to the management company with unfounded accusations that “a little lukewarm is coming out of the tap” - give her evidence. Therefore, a citizen who considers himself injured due to violations of SanPiNA regulations and wants to uphold justice, must first of all learn how to measure the temperature of hot water in an apartment. This procedure is simple, short-term and does not require ingenious improvised means.

A thermometer with a scale of 100 degrees is what measures the temperature of hot water in a tap. For measurement, a citizen needs to prepare this household appliance, then strictly adhere to the algorithm of actions, which, according to management companies, invariably leads to accurate results.

Open the faucet and let the water drain for about 3 minutes. So get rid of stagnant water, the temperature of which is traditionally lower.

Place a glass under the stream and hold it so that the liquid overflows over the edges. You can’t just take a glass from the tap - by the time you bring it to the table where you put the thermometer, the water will cool down, and the reliability of the measurement will be doubtful

Lower the thermometer into the container closer to the center.

Wait until the degrees on the device stop growing and record the result.

If the thermometer showed a temperature below the minimum level set by SanPiN, this means that it is time for the management company to set a uniform thrashing.

Where to apply?

What to do if the hot water is low temperature? A citizen needs to complain about this to the Housing and Communal Services (HCS).

Not enough heat is just one of the grounds for complaint. Housing and communal services should also be concerned if the water has an uncharacteristic color (smell, taste) or is completely absent.

There is no need to personally visit the Farm - you can call. The dispatcher will first of all check whether the decrease in the temperature of hot water in the tap is caused by a breakdown on the main line or preventive maintenance. If repairs at the station are to blame, the dispatcher will inform the citizen of the approximate time when normal water supply will be restored. If good reasons there is no violation of the SanPiN requirements, the dispatcher will record the citizen’s appeal and promise that the reaction will not have to wait long.

In order to be sure that his appeal will not be ignored, the citizen needs to write down the application number, the time of the call to the housing and communal services and the name of the employee with whom he communicated. An employee who is faced with such meticulousness will accurately ensure that the application he has accepted is considered - because he will feel responsible for fulfilling these promises.

A citizen needs to wait for the visit of an expert - according to Government Decree No. 354, an expert should appear on the doorstep no more than 2 hours after the citizen has filed a complaint. The expert will measure the temperature of the water from the tap on his own (of course, no one will believe the citizen himself). Then the housing and communal services employee will draw up an act in which he will describe whether the violation really took place, how and when the measurement was carried out. The consumer of utilities will receive one of the copies of the act in his hands - the expert will take the second copy with him.

Having with him an act indicating a violation of the norms for the temperature of hot water in an apartment building, a citizen has the right to demand from the management company a recalculation of the payment for hot water supply.

For hot water, the temperature of which drops below 40° Celsius, the consumer of services pays as for cold water.

Decree No. 354 states that the period during which a citizen has the right to recalculate ends when people from the management company come to the citizen’s home and perform a final check that confirms that the temperature of the hot water is high enough. In case of refusal to recalculate, a citizen should file a complaint against the actions of the management company with Rospotrebnadzor or the world court.

Literally the next day, the hot water “evaporated” and everything returned to normal - the temperature of the hot water dropped, it became warm ..
I realized that somewhere I made a mistake. So I decided to use the "scientific" method. So:

Target:
1. Restore normal temperature hot water.
2. Oblige the management company to recalculate utilities for hot water.

Now you need to find laws, regulations, etc. etc. which will enable this goal and ideally put these laws on monitoring to keep track of changes. To begin with, let's find out what temperature the hot water should have, otherwise, suddenly, lukewarm water is supposed to me by law;) One of the main documents on utility services:
Decree of the Government of the Russian Federation of May 6, 2011 N 354 "On the provision of public services to owners and users of premises in apartment buildings and residential buildings" (hereinafter referred to as the decree)
Appendix 1 of the resolution contains clause 5. Ensuring that the temperature of hot water at the draw-off point complies with the requirements of the legislation of the Russian Federation on technical regulation (SanPin 2.1.4.2496-09)
We look at SanPin 2.1.4.2496-09 p 2.4: "The temperature of hot water in the places of water intake, regardless of the heat supply system used, must not be lower than 60 ° C and not higher than 75 ° C. Therefore, it is necessary to officially measure the temperature of hot water, and in case of deviation from the norm, demand a solution to the problem.How to do it? Several options are possible:
Method 1
There is a whole section in the decree on this topic. clause 106 of the resolution:
"A report on a violation of the quality of a utility 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 provide his last name, first name and patronymic, the exact address 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.
07/2/2013 I called the control room, told about the problem - "in my apartment low temperature hot water flowing from the faucet warm water"- the service employee told me the data on the appeal: application No. 19 at 15.00 Moscow time and gave his last name. This is important. What does it give? Firstly, the time from which the recalculation will be made (paragraph 111 of the resolution). And secondly, the official registration of the problem, which can be referred to in further complaints and the preparation of other documents.I also talked with the residents of my entrance, found out that almost one person had such a problem. And what they wrote, called - to no avail. It's a sin not to make a collective complaint;) However, I decided to wait and see how the service company reacts.
The management company needs to check. According to paragraphs 108 and 109, in our case, the employee of the dispatch service is obliged to agree with the consumer on the date and time of the verification of the fact of the low temperature of hot water. After that, within 2 hours from the moment of receiving a message from the consumer about the violation of the quality of the utility service, set the time for the inspection, unless a different time is agreed with the consumer. There is a nuance here - it is necessary to indicate your reliable data (full name, contacts) so that they contact you and there is no misunderstanding on the part of the management company. Then, when they came to you and recorded everything, at the end of the check, an act is drawn up. And here three options are possible (I quote paragraph 109):

"1. If during the inspection the fact of a violation of the quality of the utility service is established, then the date and time of the inspection, the identified violations of the quality parameters of the utility service, the methods (tools) used during the inspection to identify such violations, conclusions about the date and time the beginning of violations of the quality of public services.
2. If during the inspection the fact of violation of the quality of the communal service is not confirmed, then the inspection report indicates the absence of the fact of violation of the quality of the communal service.
3. If during the inspection a dispute arose regarding the fact of a violation of the quality of the utility service and (or) the amount of deviation from the quality parameters of the utility service established in Appendix N1 to these Rules, then the inspection report is drawn up in accordance with these Rules.

I had the first option: because. during a call to the dispatch service, I indicated the data of my grandmother, then they came to her during my absence. So be sure to include your details when contacting us. I was lucky at the time of the test, the temperature of the water from the hot water tap was 52 degrees, which is below normal. 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 persons participating in the verification.However, for unknown reasons, the second copy was never sent to me, although by phone Chief Engineer stated that within 3 days from the date of the check they would send an act. Hence the question why they didn’t issue it on the spot, because the act can be signed by representatives of the Criminal Code. On the one hand, this is a plus - an extra flaw on the part of the Criminal Code, which will help in the proceedings, but there should be paper - as this is a document confirming the provision of public services inadequate quality. I'll have to write again.
Method 2

Similar to method 1, only after contacting the control room, you also write a complaint to the state housing inspectorate. You should also contact the inspectorate if you have a dispute regarding the verification of the fact that the service was rendered of inadequate quality (paragraph 110 of the resolution). All the same, I probably have to write there.Recently, I called the dispatcher again, 10 minutes after the call, a DEZ employee came (he was in our house at that moment) touched the water with his finger, agreed that it was cold. He said that there are not enough people, engineers, etc., etc. to fix the problem and so on. I did not understand everything from his words, but one thing is clear - the mess is still the same. So along the way, you should find out - this mess is manageable and planned in advance, or is a coincidence. From communication with neighbors and with my grandmother, I found out that employees of the service company tell each tenant - “everything is in order, only you have one (one) such a situation, and so on.” Grandma was generally told “let’s go through the neighbors and collect signatures from all that everything is fine". The version of a coincidence becomes less likely, but facts are needed. This separate work, which goes beyond the goals and requires a set of measures - in general, I will not stay idle.

I wrote this letter:

Scattered across mailboxes your entrance. On Mon 08/11/13 I will prepare a collective complaint against the management company about the low temperature of hot water in the apartments and send it to the housing inspection of the city of Moscow. I wonder how the inspectorate will react to this, in theory, they should have bonuses by identifying jambs in the work of the management company. Let's see what's what)

Such amenities as heat, gas, electricity and water are perceived by us as part of the usual comfort of a city dweller. It is especially difficult for us without hot water, which is sometimes planned to be turned off.

But what if hot water can only be called that because it comes from the corresponding tap. In fact, it is slightly warm, but not hot at all. Let's look at the standards and find out what temperature it should be.

Hot water temperature standard according to SNiP

Temperature regime of hot water supplied to water supply systems apartment building, are established by the Sanitary and Epidemiological Service, SNIPs and GOSTs.

SanPiN Resolution 2.1.4.2496-09 lists the following hot water standards:

• at least 60 degrees in the open heating system;
• at least 50 degrees in a closed heating system;
• not higher than 75 degrees, regardless of the system.

The lower threshold is set in a range that allows you to protect water from pathogenic bacteria. If the upper limit (75 degrees) is exceeded for any reason, it may cause damage plastic system water supply. Such systems are now in every modern house.

The temperature of hot water from the tap should not be lower than 60 0 С and not higher than 75 0 С

It should be noted that in the legislation one can find tolerances hot water temperature. They should not be more than:

• three degrees in the daytime;
• five degrees at night.

If the deviations are greater than the specified values, consumers have the right to demand a reduction in fees. When the water in the hot tap does not reach 40 degrees in temperature, its cost should be calculated according to the standard, as for cold water supply.

How to measure the temperature of hot water in the faucet

Before making a complaint and demanding measurements, you can independently check the temperature of the water from the hot tap. To do this, you must first open the tap and let the water flow for two to three minutes. This is necessary so that the water in the water supply system takes a constant temperature. Then it is collected in a container where the thermometer is immersed. You can use common appliance for water.

After the temperature on the thermometer becomes constant, write it down and take a series of measurements at other times of the day. When, during all the measurements made, the instrument column shows the temperature below the standard, you should contact the management company.

What to do if the DHW supply is not up to standard

Reporting a discrepancy between the water temperature and the specified standards based on the results of the measurements made is mandatory, since you pay for the resource and have the right to demand compliance with the standards. Applications Management Company should be accepted both in writing and by telephone.

All actions aimed at finding out the causes of violations must be recorded by the dispatcher. He, in turn, is obliged to notify the applicant about the work being done on the water supply line. In the absence of problems on the water supply line, a representative of the management company (UK) is obliged to come to the address indicated in the application and take measurements. The estimated exit time is set within two hours, unless otherwise agreed with the applicant.

In the process of taking measurements in the presence of a representative of the Criminal Code, all thermometer readings are recorded in an act. This document must be completed. It is on its basis that you can demand the recalculation of fees for hot water supply. Two copies are made: one for the applicant, the second - in the Criminal Code.

If temperature regime is violated regularly and repeatedly, the consumer has the right to contact the utility service with a complaint. It will certainly be considered, but it is important to draw up the document correctly and argue the problem as clearly as possible.

Main points of complaint:

1. In the header, in addition to the organization and official to whom it is addressed, it is necessary to indicate your data: full name, full address of registration, phone number for contact.
2. The text should contain all the information about the problem, indicating the measurements made. Data is taken from the act drawn up jointly with the representative of the Criminal Code. Be sure to indicate the date when the measurements were taken, the temperature according to the readings of the device and the data of the representative. Here you can also specify the dates of appeals and visits on this issue.
3. At the end, the complaint contains requirements to eliminate the causes of deviations from the standards.
4. The complaint is sealed with the signature of the person concerned and the date of its preparation.

The complaint can be made in printed form or by hand in two copies. One of them is transferred to the management company. At the same time, during a personal visit, you can be required to register it in the presence of the applicant and put the incoming number on the second copy, which remains in the hands of the applicant.

Sample application for measuring the temperature of hot water —

The term for considering a complaint is set at 30 days, although management companies often respond to written requests much faster. The speed of solving the problem can be affected by a collective complaint if there are several dissatisfied with the quality of the water.

In case of inaction of the Criminal Code, one should contact the state supervision structures - Rospotrebnadzor and the prosecutor's office.

The temperature of hot water depends both on the type of water supply systems and on the time of day. At night, the temperature can drop by 2 degrees lower than during the day.

Temperature standards

The standards for all indicators in the apartment must comply with SanPiN ( sanitary rules and norms) and GOSTs. SanPiN regulations for hot water in 2017 have not changed. These standards are adopted for reasons of expediency, since too cold or hot water can be harmful to human health. Citizens pay not only for the delivery of water, but also for the convenience associated with a certain temperature.

The water temperature directly depends on the type of water supply. Simply - cold and hot water must be of their own, a certain temperature. The temperature of hot water should be 60-75 degrees (not higher than 60 ° C and not lower than 75 degrees). This temperature is required for all places of water intake.

In a closed system, the water temperature should be 50 degrees (this is the minimum), in an open system - 60 ° C.

The following deviations are allowed by the rules for the provision of public services:

• decrease by 5 degrees during the night (from 0 to 5.00 in the morning);
• daytime temperature drop by 3 o C (from 5.00 to 0.00).

These rules are in place for human safety. With hotter water than the standard, you can get burned with varying degrees of severity. Especially dangerous fever for small children who can turn on the faucet, but do not immediately figure out how to dodge or turn off the flow of water.

But not only therefore, the temperature of hot water should not exceed 75 degrees. The fact is that the plumbing in the vast majority of modern apartments consists of plastic. And, of course, increased temperature negatively affects all plastic parts.

An increase in temperature up to 76% is considered a violation. Just like its decrease to 56 degrees during the day or up to 54% at night.

How to take your own temperature

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 in accordance with all the rules. It is possible to present requirements to a service organization only when measuring according to all the rules with the minimum allowable error. The thermometer must be in good working order and contain a 100 degree scale.

The algorithm of actions should be as follows:

1. Open a hot water faucet while cold water should be closed. Water should drain within 3 minutes. Stagnant water is usually a little lower, so it should come off.
2. Substitute a container under the stream of water, preferably with a volume of at least a liter.
3. Without rearranging the container, measure directly under running 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, it is not necessary to rearrange the container, let the water overflow.
4. When the numbers on the thermometer are fixed, remember the result.

If the temperature does not comply with SanPiN, then you need to complain to the housing and communal services. It is best to call the control room first to find out what caused the increase. It is possible that you do not have to write a statement, since the change in temperature can be explained by preventive work or repairs on the highway. In this case, the dispatcher must report at what time the temperature returns to normal.

If there are no good reasons, then you should write a statement with a request 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 transfer your complaint for consideration.

On the video about checking the temperature of hot water

Suspend the water supply in the event of a scheduled inspection can be no more than 4 hours. It is at this time that the temperature of the water in the tap may change. After a while, she will recover.

Hot water should provide residents with comfort and safety plumbing use water resources according to all sanitary standards hot water temperature in an apartment building. Equipment for the supply and distribution of resources to consumption points throughout the building system is installed in accordance with standards. Such services should be safe, reliable and inexpensive.

DHW temperature

A little about what temperature the water should be. The temperature range of hot water is from 60 to 75 degrees Celsius. Such values ​​are chosen for a reason. When the temperature of the water in the tap is above the recommended limits, then burns are possible, especially on the sensitive skin of the child. Therefore, the standard must be strictly observed in children's institutions and health care organizations.

Many tenants are interested in why such a temperature value. When determining the temperature regime for the supply of hot water, we proceeded from such a phenomenon as the reproduction of pathological microorganisms. The risk of burn injuries was also taken into account.

The temperature difference of hot water should be such that harmful bacteria cease to exist, and burns do not occur. Warm fresh liquid is an excellent habitat for legionella, which is extremely dangerous and multiplies in central water supply(sewerage, heating). For example, not so long ago in the city of Verkhnyaya Pyshma, due to this bacterium, which entered apartments through the water supply, there were epidemiological forms of pneumonia in 160 residents of the city, and five people died in the hospital.

As a result, it is not necessary to provide employees of the managing organization with pretexts to blame all these issues on the residents of the house, because the sanitary standards for the temperature of hot water in apartments are enshrined in laws, and the causal relationships of owners and tenants of apartments do not apply. The main thing that is needed from residents is to be aware of who to write an application for recalculation of payments for housing and communal services, which were provided poorly.

IMPORTANT! Research that determines the temperature of hot water in an apartment should be entrusted to an accredited company that has license certificates that allow such activities to be carried out.

Hot water not up to standard

After the temperature measurements have been taken, and the standard for the temperature of hot water that is supplied to the dwelling is not met, you should complain to the appropriate organization. In addition to deviations in temperature readings, there may be the following anomalies:

• it happens that after turning on the tap, the water flows out warm, and sometimes cold, which is unacceptable;
• it also happens that tap water comes in a non-standard color and does not smell very pleasant;
• no hot water at all.

Unfortunately, the quality of services provided by companies is of inadequate quality, for which the perpetrators must be held accountable. When real estate owners are concerned with such problems, then you need to call the employees of the managing organization or to find out and eliminate the causes of the violations.

At the same time, it should be borne in mind that all apartment owners have the right to demand not only the elimination of prerequisites, and in as much as possible a short time, but also to perform for hot water, and when it is not in the water supply, then do not even pay for this service.

But it is often difficult for company employees to independently prove the violations that occur among residents, they are in no hurry to lay responsibility on themselves. In such situations, it is necessary to contact other licensed organizations that conduct an independent examination.

Where to go

If hot water deviates from the current standards, and the quality of the services provided is low, then the apartment owners write. An application must be added to it in the form of a copy of the examination conducted by an independent organization. After that, it remains only to wait for the Criminal Code to solve this problem, which will take time.

When the management company does nothing or only replies come in response, then the answer to the question of what to do in case of deviations is to go further. To the housing inspectorate or the prosecutor's office. In reality, many tenants often encounter similar situations when the management company does not want to eliminate its flaws, but only nods at supposedly objective circumstances.

They often say that they are not authorized to resolve such issues, they are not in their competence, and UK is not responsible for the operation of pipelines. You can also find out that they are not at all aware of what temperature the DHW should be at the outlet of the draw-off point, so the management company is not going to do anything to resolve this issue.

It is necessary to firmly defend your own rights, because only the management companies are entrusted with the mission of public services. DHW temperature at a rate of 60 to 75 degrees should be provided by management companies. Responding to all complaints and fixing problems is their direct duty. If this is not done, then the owners have the right to file a complaint with the prosecutor's office and Rospotrebnadzor.

Supervisory authorities

When deviations from hot water standards are detected, the management company negotiates with, and in some situations repairs the engineering and communication system on its own. It often happens that in order to save on users, some negligent contractors shy away from conducting repair work pipelines, which they are simply obliged to fulfill. In this case, you need to boldly complain to the prosecutor's office or Rospotrebnadzor.

Moreover, it is possible not to redirect the complaint to the supervisory authorities, as tenants often do. Know that you can always negotiate with the management company and recalculate hot water in a good way. In practice, many managing organizations themselves are hostages of such situations, when literally nothing depends on them.

Before you write an application for the recalculation of payment for utility bills due to services rendered of poor quality, you should find out all the subtleties of this issue, explore the pitfalls. This must be done in order not to get into various unpleasant situations. Everything can be solved in a civilized manner and according to the law.

But when all the attempts made have not led to any result, then the owners of residential premises should contact the supervisory structures. Then things will go much faster, and when problem situation actually, it will be solved in a fairly short time.

Cold water temperature

The quality of water supplied to apartments for drinking and household purposes must meet GOST and SanPin. The temperature spread of cold water is not regulated by any standards, but you should be aware that the indicators depend on the season. This corresponds to the values ​​in the sources of water intake and the temperature of the ground where the pipeline is laid.

IN main pipes the temperature reaches almost minus readings due to the fact that at high pressure the liquid freezes more slowly. Although the temperature of cold water in the tap is not regulated by regulations, regional regulatory authorities recommend a range of 4 to 20 degrees Celsius. IN winter period in some rooms it is very hot, while in others, on the contrary, it is cold. This is uncomfortable, even if the standards are observed, so they are regulated by the management company during the heating season.

Accidents affecting performance

Warming of cold water often occurs due to mixing at draw-off points for central hot water supply. This is due to uneven pressure in the pipes and a poorly adjusted mixer, which stands on the distributing riser. Sometimes mixing occurs during sanitary and technological work in the technical underground.

You need to know that all problems, when the temperature of cold water in the tap rises, the management company is obliged to eliminate as much as possible as soon as possible. Otherwise, damage to the expensive household appliances, washing and dishwashers that operate on cold water from water pipes.

To prevent this from happening, during the operation of any water heating devices, it is necessary to cut off the hot water supply circuits in time during the operation of the heating element, as well as to cut off the boilers when taking water from the common riser. With open double-circuit technology, hot and cold water often mix, which leads to high pressure, and then to breakdown of plumbing equipment.
