Permissible hot water temperature. Standard and permissible deviation of hot water temperature in the apartment

Hot water should provide residents with comfort and safety plumbing use water resources according to all sanitary standards temperature hot water 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 determined temperature regime supply of hot water, then 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 sometimes 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 Management Company does nothing or only unsubscribes come in response, then to the question of what to do in case of deviations, the answer 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 utilities. The DHW temperature at a rate of 60 to 75 degrees must 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.

AT 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. AT 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 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, often hot and cold water mixed, which leads to a large pressure, and then the breakdown of plumbing equipment.

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 regulations 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.

AT closed system the water temperature should be 50 degrees (this is the minimum), in the open - 60 o C.

The following deviations are allowed by the rules for the provision of 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. More hot water than according to 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 vast majority of plumbing modern apartments is made 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 the hot water faucet, while the cold water must 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 a good reasons No, 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.

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 in summer season for the period 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 connected not only with the direct observance of the temperature regime in order to provide residents with hot water.

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 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:

• 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 decision 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 need. 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°C) must not be exceeded.

Is a water heater necessary?

AT 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 tenants are forced to heat water, say, on gas stove, water heater owners release yourself from such a duty;

• reluctance stay without hot water on the 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 is 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 daily a 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 carry out 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.

The 2019 standards that determine the temperature of hot water supplied to the room are established by a special document - the SanPin order. Just like last year, this indicator remained unchanged, which means that all Russians living in multi-storey buildings have the right to demand full provision from the service organization comfortable living in apartments, including hot water supply.

It should be noted that the problem is not even that the water has a temperature regime that is not quite suitable for use. The problem is related to the danger posed by a water supply that is treated contrary to accepted technology. Today we will talk about what norms are in force in Russia and what rights the residents of MKD are endowed with.

Not every owner knows that the water temperature is determined by the water supply system. For each type of plumbing device, the indicator is set to its own, such as:

• for an open system - from 60 degrees Celsius;
• in a closed system - from 50 degrees Celsius.

According to the standards of 2019, the DHW temperature should not be higher than 75 degrees. The top level is no longer dependent on the type and configuration of the system.

This standard must be observed very strictly, and there are several well-founded reasons for this. In particular, we are talking about such important points:

• too low a temperature indicator can cause the liquid in the pipes to become viscous, and infectious agents will begin to appear in it. When the temperature threshold is observed, harmful bacteria die and do not reach the human body;
• Excessively hot water can cause severe burns to the user. Even at a temperature of 55 degrees, the risk of getting burned is very high, so to avoid such a situation in open system water supplies usually “mix in” cold water as well;
• excessive rise in temperature DHW mode may cause deformation of parts of the plumbing system made of plastic. The danger of this kind began to rise, especially in last years when people more and more often install plastic pipes in the apartment.

It will be very difficult to find the guilty person here, since there were no measurements of the temperature of hot water initially. This means that compensation will also not work.

What deviations from the norms are allowed?

Sharp drop and rise DHW temperature can lead to serious violations and failures in the water supply system and even to possible injuries to citizens. However, there are a number of permitted deviations from the established standards. It is about the following points:

• in the daytime (from 5 am to 24 pm), the water temperature can be lowered by no more than 3 degrees, that is, up to 57 degrees Celsius;
• at night (from midnight to 5 am) maximum possible threshold reduction is 5 degrees, that is, up to 55 degrees Celsius.

Suspension of DHW can occur in two situations. In the first case, we are talking about an accident. The second option is to conduct planned preventive measures. In any case, the occupants should not suffer, and the maximum allowable hot water shutdown period is 4 hours.

Ways to find out the temperature regime of water

To defend your point of view and receive compensation for violation of rights, it is not enough to go to the Criminal Code or write. It is necessary to present them with irrefutable facts that not too much flows from the tap. warm water, preferably obtained empirically and not subject to doubt.

When an injured tenant wants justice and compensation, the first step is to find out what the current performance of the property is. The procedure is quite simple and short. Moreover, no complicated and obscure devices are required for this.

To get the information you need, you will need to arm yourself with a simple thermometer with a scale of 100 degrees. It is this device that is suitable for measuring the desired indicator. When using the device, you will need to strictly follow the specified algorithm. This will give you the most accurate results. The procedure should be as follows:

1. Open the hot water faucet and wait at least 3 minutes. This makes it possible to remove the accumulated liquid, the performance of which is somewhat lower.
2. Substitute a glass under the jet and hold it so that the water overflows it. You can’t just take water into a glass and take it to the table, because during this time it can cool down by a couple of degrees.
3. It is important to lower the thermometer carefully into the glass closer to the center.
4. After the reading stops rising, you can record the data.

If the temperature obtained is below the permitted one, then it will be necessary to file a complaint with the Criminal Code or the housing and communal services department. If there is no reaction, then the next instance for a complaint is the prosecutor's office and the court.

Conclusion

In conclusion, it is worth noting that if the temperature of hot water drops below 40 degrees Celsius, the tenant will pay for it as for cold water supply. During the time of violation of existing standards, a citizen also has the right to demand a recalculation.
