Standard indicators of hot water temperature in the apartment

Temperature standards for hot water

According to the current law, the temperature of hot water must be at least 50 0C. However, there are some restrictions on this:

1. The standard applies only to residential buildings connected to a central water supply system (DHW).
2. Also, the minimum temperature depends on the type of system used. In an open system it is at least 60 0, and in a closed system – from 50 0. This is due to the fact that in the first case there is a pronounced heat loss.
3. Permitted deviations from the norm depend on the time of day. It is allowed that in the period between 00:00 and 05:00 the temperature values ​​of the water in the pipeline are 5 degrees less, and the rest of the time - by 3 0. Based on this, the normal temperature during the day is 57 0, and at night - 55 0.

Due to the reduced temperature, the flow rate of the supplied liquid increases. And as a result, the cost of utilities increases. If the water temperature in all water intake areas is low, pathogenic bacteria will begin to multiply. Under their influence, pathological processes develop in the human body.

For example, legionella can settle in warm fresh water. This is a dangerous microorganism that multiplies quickly and causes pneumonia and other serious pathologies.

The maximum temperature value is 75 0. This allows you to set suitable water temperatures during washing. Washing with too hot water is prohibited - it can negatively affect human health, causing instant burns. In addition, it causes deformations in the water supply system, especially often damaging plastic pipes.

SanPin standard

SanPin 2.1.2496-09 is an important legislative act that defines the minimum (60 0) and maximum (75 0) temperature values ​​for hot water. The permitted differences from the standards are also indicated here.

It notes that at the entrance to the house the temperature may be slightly higher. This is due to the fact that when passing through pipeline networks, the liquid may cool down slightly.

SNIP and GOST standards

Also, the standard temperature of cold and hot water in an apartment building is determined by SNIPA and GOST standards. In all legislative acts, the meaning of the standards is the same, but issues on the topic of hot water are considered from different angles.

According to GOST, the normal temperature of hot water starts from 60 0 for an open type system, and from 50 0 for a closed one. In this case, the maximum temperature in both cases is 75 0. If it is below 40 0, the cost of hot water is calculated as for cold water.

On the topic of hot water supply, one of the most important documents is the SNiP act 2.04.01-85. In 2013, adjustments were added to it under the name SP 30.13330.2012. This act is expanded, since it additionally addresses issues related to water supply, sewerage systems, and poor quality water supply.

9. Recommendations .

• Defects in the completed facade work, as well as the quality of the work performed on the construction of external walls and the installation of stained glass, can be determined provided that the facade street walls are completely opened and the cost of dismantling work is determined in agreement with the owner of the apartment. The specified work, due to its labor intensity and duration, taking into account the restoration of the normal heat resistance of the structure, is not included in the scope of this conclusion.
• Request an energy passport for the house from the management company in order to assess the proposed measures of the management company (MC) to eliminate freezing of wall and window structures.

How to measure water temperature correctly?

To check the quality of the supplied water, the user can measure its temperature. If the received data differs from normal values, he can complain to the service provider.

When taking measurements, certain rules must be followed. The work is carried out in the following sequence:

1. Run water from the tap and leave for 3 minutes. During this time, the water will drain, so the resulting calculations will be as accurate as possible. If you measure the temperature immediately, the liquid may be colder or hotter.
2. Fill a container with a large neck with water. After this, there is no need to close the mixer; water should constantly flow through the edges of the vessel.
3. Measure the temperature with a household water thermometer. It must be in good working order, otherwise the obtained values ​​may not correspond to reality.
4. Record the obtained indicators and compare them with normal values.
5. To ensure that the data is correct, it is recommended to repeat the manipulations several times.

Measurements taken independently will not have legal force. But it is necessary to carry out such measurements. After this, it will be possible to decide whether it is necessary to call independent experts.

If the temperature of the liquid from the tap differs noticeably from normal values, you must contact the housing and communal services department. Its representatives will take measurements and draw up a document that has legal force.

Attention! Assessment by independent experts is not a free procedure. But if deviations are found, you can ensure that the management company (MC) makes the payment.

Sample temperature measurement report

When drawing up the act, the date and city are indicated at the top.

Then the act itself is drawn up. It looks something like this:

“We, the undersigned, the owner of the apartment ______________ (indicate address, apartment number) and the representative of Management Company RSU-7 LLC _______________ (full name of the representative) drew up a report on measuring the water temperature in the kitchen and bathroom. The measurements were carried out at ____ (indicate the exact time) with a water thermometer, taking into account the Methodological Instructions MUK 4.3.2900-11 (these instructions must be written down).

The hot water temperature after draining for three minutes is ______ degrees. The thermometer ball was located in the center of the container. The measurements were carried out with a continuous flow of water into the vessel.

The measurement result was determined _____ minutes after inserting the thermometer into the container with the liquid being tested. The air temperature in the room at the time of measurements was _____ degrees.

The act is drawn up in ____copies.

Signed:

Management Company LLC "RSU-7" ___________________________

Owner ______________________________.”

Permitted deviations

The DHW temperature can deviate downward by 3 0 during the day and by 5 0 between 00:00 and 05:00. Moreover, its indicators should not exceed 75 0 at any time of the day. If the deviations are more significant, consumers can file a complaint.

Attention! For every 3 degrees difference from the norm, a person can demand a reduction in the cost of services by 0.1% for each hour of using hot water. If its values ​​are less than 40 degrees, a person may demand that payment be made as for cold water.

Poor water quality

Temperature is not the only indicator of water quality. The liquid must also have a certain pressure and purity.

If the pressure is low, the water will flow in a thin stream. And if the pressure is high, it can cause deformation of the components of the plumbing system. The pressure in the pipes should be 0.3-4.5 AT. If it does not meet these parameters, you need to contact the Criminal Code for recalculation.

There may be various impurities in the water - rust, clay, etc. If water is regularly supplied with such impurities, you need to write a complaint to the water utility. Cleaning systems will be inspected together with the housing office service.

How to file a complaint

First you need to contact the housing and communal services department. Perhaps the reasons for the deviations are related to breakdowns on the highway and repair work.

Attention! In accordance with the law, housing and communal services must respond no later than 120 minutes after the request.

If the problems are persistent and a person is not satisfied with the quality of the hot water service, he can file a complaint with the Criminal Code. But during this he must take into account the following points:

1. The application does not have to be printed; it can be written manually.
2. In the upper right corner, indicate the applicant’s personal information – full name, place of residence, contact information.
3. It is mandatory to write the name of the organization against which the complaint is being made. You can also send a claim to a specific person who is involved in solving hot water supply problems.
4. The main part of the complaint indicates the reasons why the person had to write it (for example, temperature readings do not correspond to the norm, incorrect pressure in the system, presence of impurities in the water). You also need to describe the essence of the current problem and identify attempts to solve it (where the consumer applied, what was the response to his request). It is recommended to make references to the standards that are in force in the Russian Federation.
5. After this, you must indicate the attached documents.
6. At the end, the date of drawing up the claim is noted, and the applicant signs.
7. The completed application receives its own code, which can be used to track it in the future.

If the Criminal Code refuses to solve the current problem, you must contact the police station. To confirm your claims, you must agree to an independent examination. If the expert does not identify any violations, the claim will be denied.

The presence of a certificate is mandatory; it should be checked with workers who come to the site.

To draw it up, you should assemble a commission, which includes a representative of the management company, the apartment’s tenant, and other persons.

1. Outside, if it happens in winter, it should not be less than five degrees below zero.
2. The commission arrives at the applicant at the time agreed upon with him.
3. The temperature in each room should be measured separately.

The commission must have a form of the act.

If it is compiled without it, the following points must be observed:

• Then there is a list of housing characteristics. The number of rooms, the floor of the room, and how insulated the housing is.
• The document indicates the full and exact address of the apartment. It is also necessary to record information about the owner.
• The technical characteristics of the heating system are also given.

One remains at the institution, the other is marked with an incoming number and date of receipt. The applicant keeps this copy as a guarantee that his complaint will be considered. Attention

Recalculation of payment for hot water supply

If water is supplied of poor quality, the cost of the service is recalculated. The receipt has a “Recalculation” column, which adjusts the payment amount if there are certain grounds for this. The difference between the amount paid and the actual amount is credited to the future payment account.

Recalculation is made after the consumer submits an application. It must be accompanied by a protocol confirming the violations identified.

If payment is calculated without meters, according to the standards, recalculation is possible if the user is absent for more than 5 days. But he must present evidence for this - tickets, discharge from the hospital and others.

Attention! Recalculation must be completed within 5 working days. If the management company does not agree with the complaint, the tenant must be sent a written reasoned refusal within 30 days.

Sample application

When drawing up an application for recalculation of hot water, the following aspects are taken into account:

1. In the upper right corner it is indicated to whom the application is being submitted (to the director of the HOA, his full name) and from whom.
2. Then, “Application” is written in the center of the sheet, and below it is necessary to write “about the recalculation of fees for hot water.”
3. The text of the statement should look something like this:

“According to my application, the hot water temperature was measured in the apartment I own at ___________ (indicate the exact address). Violations were detected as the temperature was ______ degrees. After this, an inspection report was drawn up. Based on this, it was determined that I was receiving a low-quality service that did not meet regulatory requirements.

In this regard, I ask:

– Recalculate the payment for hot water from the period –_________ (indicate the date when the check was carried out).

– Carry out the necessary work to ensure the supply of water at a temperature that meets sanitary standards.

1. Below, indicate your full name and date of writing the application, and sign.

Attach a copy of the inspection report to the application. If there are grounds, the complaint must be satisfied within 5 working days after filing.

Why is the act needed?

When the apartment is still cold during the heating season, the air temperature is clearly different from the standard, residents begin to complain first to the Management Company, then to Rospotrebnadzor or the Housing Inspectorate. They want to achieve warmth in their home, as well as a repayment for low-quality services.

The application for recalculation must be accompanied by a document that will prove that the actual temperature does not correspond to the standard one. Such a document will be a measurement report, which should be drawn up and signed correctly.

To draw it up, you should assemble a commission, which includes a representative of the management company, the apartment’s tenant, and other persons.

If the management company does not want to send its employee to measure the temperature in the residential premises, apartment residents can draw up an act on their own, fulfilling the necessary requirements:

• The document will be needed to recalculate heating payments. Provided that the measurement actually shows a low temperature that does not meet the standards (even taking into account the deviation).
• The act will be attached to applications to various authorities - to the Criminal Code, to ZHI, to Rospotrebnadzor, the prosecutor's office, the court. Sometimes consumers of utility services sometimes have to go all the way with claims before the result is achieved - heat will appear in the house.
