What should the temperature of the hot water in the tap be?

How to find out how many degrees the temperature of the water in the tap is

If you do not have a special device attached to the source, you can get by with simpler methods. To do this you will need an ordinary household thermometer.

Important! Open the tap and set it to cold. Let the liquid drain for 2-3 minutes. Stagnant water in the water supply is usually located somewhat further than the one that flows out first, so for accurate measurements you should wait time.

Place any container under the faucet that will fit the thermometer. Place it at the bottom of the container. Leave everything in this position until the numbers on the thermometer stop. To ensure the most accurate temperature, it is not advisable to move the bowl.

Normal hot water temperature in an apartment building in 2020-2020 - how many degrees

Often, residents are faced with the fact that the management company does not want to recalculate and generally solve the problem with hot water. In this case, you will need the help of companies that have been accredited to carry out water temperature measurement activities.

Open the hot water tap and let the water drain to achieve a constant temperature.
Pour hot water into a container (from 1 liter).
Using a thermometer, measure the liquid in the container.
The numbers on the thermometer will indicate the temperature of the hot water.

What should be the water temperature for bathing newborns?

Hello, dear mothers, fathers, grandparents! After the baby is born, your main task will be to care for him. One of the daily hygiene procedures will be bathing the baby. And in order for your baby to like this procedure, you need to try, first of all, to make the water temperature optimal.

The temperature of the water for bathing a newborn should be warm, but it may even seem cool to us. Of course, this is difficult to understand, since we have long been accustomed to taking a long hot bath. We enjoy soaking in hot water, and we are so confident in the benefits of this procedure that it becomes very difficult to convince us of this. A newborn has completely different sensations and this must be taken into account.

Emergency situations associated with changes in tap water temperature

There are a number of basic and common problems that are directly related to exceeding the temperature of cold water in water supply systems.

Such problems arise regardless of the time of year and typical features of the water pipeline.

A slight warming of water is characterized by an increase in temperature indicators of only 6-10°C, but more pronounced fluctuations occur quite often not only in conditions of autonomous water supply to the private residential sector.

If warming of cold water coming from the tap occurs in a multi-apartment residential building with a centralized hot water supply, then we can assume the problem of mixing hot and cold water media under conditions of unequal pressure inside the pipelines. As a rule, the main reason for such mixing is a malfunction of the standard mixer installed on the distribution riser.

Somewhat less often, the mixing of aqueous media is the result of gross errors made in the process of performing basic sanitary and technical work in the technical underground, which causes hot water to be thrown into the cold main.

It is important to remember that any problems accompanied by even short-term injection of hot water into the cold water supply system must be eliminated as soon as possible. Otherwise, expensive automatic washing machines and dishwashing equipment, as well as many other household appliances operating using a cold water supply system, will fail.

To prevent warming of cold water in the tap when operating any electric water heating devices, it is necessary to promptly cut off the hot water supply circuit while using the heating element, as well as cut off boiler devices in conditions of water intake from the common riser.

The presence of two open circuits most often causes mixing of hot and cold environments, and also provokes the occurrence of powerful water hammer, and, as a result, breakdown of plumbing.

The use of flow-type gas water heating devices for hot water supply is based on the operation of the unit without adding cold water, and the temperature indicators of the water supplied to the tap should be set only by changing the heating level on the equipment itself. Otherwise, overheating and subsequent shutdown of the burners in emergency mode occurs.

GOST and SanPin set the standard temperature in the apartment. But there are certain factors that influence its change. Let's talk about them in more detail.

Is it worth installing an individual heat meter in an apartment? We’ll figure it out further.

Maximum and minimum indicators

Now let's figure out why, according to sanitary rules and regulations, hot water in the tap should be within the range of 60-75 degrees?

Because, precisely, these temperature limits guarantee the death of all harmful cocci (how to choose a built-in dishwasher).

But what about the fact that at a water temperature of +55 degrees, the likelihood of getting skin burns increases significantly?

At high levels, the plastic part of the water supply may be damaged . Pipes made of this material are found in most apartments.

To prevent this from happening, you need to open both taps (warm and cold water) at the same time.

59 or 76 degrees of hot water in the tap is already considered a deviation (I saw how to choose an automatic washing machine, see here).

The contract, which must be drawn up between the user and the service provider, must indicate that the latter guarantees the minimum temperature of the hot liquid in the apartment, regardless of the condition of communication networks and heating equipment.

For various reasons beyond anyone's control , the temperature of the hot liquid may be slightly lower than the established limits in such cases.

If an emergency occurs at the pumping station or on the main line, or if communications fail in the house in which you live.
When the relevant services carry out scheduled or preventive repair work.

It is important to know! Has the hot water supply stopped in your home?

Residents should monitor this situation. To prevent a major accident from occurring, it is necessary to immediately notify the dispatcher about the incident.

For how long can the supply of hot water in a multi-storey residential building be suspended ?

In one month – in total, no more than eight hours.
Continuously - no more than four hours.
In case of an accident – no more than one day.

The legislation of our country provides that if the above deadlines are exceeded, the service provider must reduce the tariff by 0.15% for the time the deviation from the norm occurs.

For example, if you have five days out of thirty, the indicators did not correspond to reality, then for this period the payment for services will be reduced; for the remaining period, the tariff will be charged according to established standards.

Cold water temperature in the tap

Since the generator of cold water that enters the taps of residents of apartment buildings is a centralized water supply, its temperature may vary slightly depending on various factors. Such factors include the time of year, how the pipelines are placed, what condition they are in, and many other details. However, there is a general state standard that dictates the temperature of water, which must be observed regardless of the circumstances.

It should be noted that the executive authorities have adopted a number of regulations relating to building codes and regulations. This source notes the standards for relative cold water supply to residential premises that must be observed.

Building regulations

The current Housing Code of the Russian Federation stipulates that residents who systematically pay a certain price for the supply of water resources to their homes must receive them in the amount that they require for a comfortable stay. In addition, the composition of the water must be safe for human health and not contain any dangerous impurities. However, such a source as building codes and regulations states that residents will be provided with water suitable for drinking only if it is supplied through pipelines that meet all sanitary standards.

In different regions of the Russian Federation, water quality varies significantly. In this regard, the current legislation stipulates that temperature indicators, depending on certain quality characteristics, may vary slightly in different cities and even regions. Also, the building codes and regulations indicate that during one month there may be no water in the taps of individuals for a total of eight hours. In addition, if residents are denied water supply for more than four consecutive hours on the same day, it is considered an offense.

The heat of water resources generated by the cold main does not in any way affect the level of living comfort of individuals. The same fact applies to sanitary conditions. Regarding the pressure that should be in the cold water supply circuit, the building codes and regulations state that the minimum value of this indicator is 0.03 MP, and the maximum is 0.6 MP.

What GOST says

As for the temperature indicators of cold water supplied to the homes of citizens of the Russian Federation, the state standard says practically nothing on this topic. However, what the quality and composition of water resources should be is described in some detail in this source. The following rules apply regarding the temperature characteristics of cold water:

The water temperature depends on the season. In the warm season, the water supplied to residents' taps will be slightly warmer than in cold seasons. This fact is directly related to weather conditions. The water entering a special structure, which is designed to collect water from a source, will be much warmer in summer than in winter. In addition, a hydraulic structure designed to supply and drain water resources in a certain direction, called a water pipeline, is located close to the soil, the temperature of which also affects the temperature of the water.
Temperature standards are set by the supplier. Since the current legislation did not regulate temperature indicators that are directly related to cold tap water, each individual organization that provides services of this nature independently determines these values. In most cases, the minimum limit is set at four degrees Celsius, and the maximum at twenty degrees.

What temperature is the best water to drink?

In the summer, you want cool water to refresh yourself from the hot weather and scorching sun, so that you can feel the coolness spreading throughout your body with every sip. In winter, you want to drink scalding hot tea or coffee, which you have to blow on before taking a sip so that the steam warms your face and hands holding the cup. But in fact, the optimal water temperature lies in the golden mean and the influence of ambient temperature is not even that significant.

The best water to drink is water that is close to body temperature or slightly warmer. Warm water has many beneficial properties and is extremely beneficial for the body, here are some interesting facts:

Warm water is absorbed faster by the body and causes a feeling of quenching thirst.
Drinking water that is similar in temperature to body temperature has a better effect on digestion and improves blood circulation in organs involved in the digestive process, helping the body better absorb fatty and high-calorie foods.
Warm water also reduces the feeling of hunger, which is difficult to overestimate for those who are trying to lose weight and get rid of extra pounds.
Studies have shown that slightly warmed water reduces muscle spasms and pain, which is sure to be useful for athletes and people leading an active lifestyle.
A glass of warm water in the morning before meals helps speed up the process of awakening the body from sleep and replenishes fluid losses at night.

The easiest way to drink warm water is to use a cooler, which is easy to find in our catalog, and we will deliver it along with water completely free of charge to your home or office.

Fatal mistakes in drinking cool drinks The most incorrect example of drinking cool water and other drinks is drinking during meals, especially if it is fatty, high-calorie or carbohydrate-rich food, especially if the water is very cold, and worst of all, if there is still ice floating in it. From such proximity in your meal there is one harm, not even just one, but a whole list:

Cold water prevents the body from experiencing a feeling of satiety, which is why the feeling of satisfaction of hunger comes with a strong delay, that is, it inevitably leads to overeating.
Cold water worsens digestive processes, because they are very dependent on temperature, or rather on its lower level, which means food will not be absorbed properly.
Fatty foods with cold water are generally a time bomb for the human body, because fat hardens and becomes unsuitable for absorption by the body, in this form it is several tens of times more dangerous for the body.
It is believed that cold water quenches thirst better, but this is not true at all. In multiple tests, people who were given warm water drank much less of it than people who were given cold water.

And it’s the same in your house, right? Do you know what you water and grow?

It is also believed that cold water cools the body, but this is only partly true, because when cold water enters, the body urgently tries to warm up and, instead of simply cooling down, begins to produce additional heat, which is unnecessary during the heat. This behavior of the body leads to increased water consumption, and if you drink cold water every time, then thirst will practically not leave the person, and if the body is oversaturated with water, increased sweating will appear.

Therefore, we advise you to always drink water at room temperature, slightly cooled or heated depending on the time of year. If you really want to drink cold water or drinks with ice, then try to do this half an hour before meals or half an hour after, so as not to interfere with the digestive processes. In order for you to always have warm or chilled water at hand, in our catalog you can choose a tabletop or floor-mounted water cooler with water heating and cooling functions that suits you. With our express free delivery, your wait is minimal and your water is guaranteed to be clean and good for your health.

At what temperature does water freeze

When pressure changes, often associated with being at different altitudes, the freezing point of water begins to differ radically from the standard one characteristic of normal conditions. Crystallization of water at altitude occurs at the following temperature values:

In Russia and Europe, temperature is measured on the Celsius scale, the highest value of which is 100 degrees.
The American scientist Fahrenheit developed his own scale with 180 divisions.
There is another unit of temperature measurement - the kelvin, named after the English physicist Thomson, who received the title of Lord Kelvin.

Possible accidents due to changes in water temperature

Emergency situations with cold water are associated with its warming. It usually warms slightly (less than 10 degrees Celsius). The problem is that the hot and cold water environment at the station coincided. This happens quite often, and a faulty mixer in waterworks is to blame. This device is expensive, so organizations often minimize its importance by not changing it on time. However, even such a slight excess of the average can have dire consequences. The bottom line is that due to mixing cold and hot, the composition of cold water changes for the worse. Hot water contains slightly more hazardous substances than cold water.

Washing machines using cold water may be damaged due to this excess.

If you notice such violations, you must contact the management organization to resolve the problem. The water temperature must be restored as soon as possible.

What temperature should hot water in the tap be according to GOST 2020

It is necessary to preserve the drawn up acts and documents. Due to deviations, the price must be changed for the period during which the consumer’s rights were violated. There are principles for paying for utility services, which are enshrined in the Decree of the Government of the Russian Federation. There you can also find information about the provision of low-quality services and the rules for their payment. Hot water must flow uninterruptedly, and with the proper temperature and quality.

Recalculation is made when the deviation from the norm is 3 degrees. Moreover, this applies to increasing and decreasing temperature. The answer will be the amount that is considered a discount for the supply of low-quality water. These simple tips will help you sort out all the issues.

Pouring cold water

Tell your work colleagues and family about your grandiose plans. Give a specific date. For example, tomorrow's date. Why wait longer? You know that at work they will definitely ask about your successes, but admitting your weakness will be simply awkward. This is a very effective method. It turns out that you are making a promise not only to yourself, which could easily be forgotten, but also to the outside world.
Buy a bucket for hardening. And let it be only yours. Go to the store, choose a fun, bright, cheerful bucket. Warn all your relatives that this is your hardening container and throwing a floor rag into it will be regarded as a crime. It will be just wonderful if your family gets into this idea with you.

Even ancient healers treated ailments using this procedure. Healers knew about the wonderful properties of water and skillfully applied them in practice. To this day, dousing is considered one of the most accessible, safe and effective ways to combat many diseases.

If the water is not hot, ask for recalculation

People know that there are standards. By Decree of the Ministry of Housing and Communal Services of the Republic of Belarus dated December 3, 2010 No. 25 “On the requirements for the quality of basic housing and communal services”, the temperature of hot water supplied to apartments must be at least 50 °C. If the standard is not met, then you can request a recalculation for the service provided. To do this, you need to submit an application to the Gantsevichi RZHKH, which is obliged to consider it, study the situation and, upon confirmation of the fact, carry out a recalculation, reducing the amount of the fee.

Residents of about ten communal houses from which complaints were received received a recalculation for May. They were charged for heating the water to 30-48 degrees instead of 50. According to another housing and communal services specialist, residents of cooperative houses always pay only for the actual heating of water, because each house has meters, according to the readings of which the payment for heating water for each month is calculated exactly in this house. “Based on applications, we take statistics on meter readings in heating stations and calculate payments,” the specialist explained.

Standards according to GOST

SNIP does not establish exact standards for the temperature of cold tap water, as it may depend on several factors.

Season. In spring and summer, the temperature of the liquid may be slightly higher than at other times of the year. Since it is at this time that the sun’s rays heat the soil in which the water supply and water intake structures are laid.
Water supply company. The fact that temperature standards are not specified in legislative and administrative acts allows suppliers to set them themselves. Typically, the minimum temperature threshold for cold tap water is 4 degrees, and the maximum is 20.

The minimum and maximum thresholds will be specified in the contract with the organization supplying the resource. Therefore, you can easily check the company for compliance with the established framework.

What temperature should hot water in the tap be according to GOST 2020?

Temperature norm in accordance with the law: what should it be according to GOST? According to the building codes and regulations applied to the internal water supply and sewerage systems of buildings (SNiP 2.04.01-85), the minimum temperature of hot water in a residential area should be up to 60-75 degrees Celsius. The same standards are established in the Sanitary and Epidemiological Rules and Norms SanPiN 2.1.4.2496-09.

Hot water temperature standard

If the temperature of the supplied hot water is reduced for unknown reasons, it is necessary to agree on the day and hour of measurements. Next, after taking measurements, a report is drawn up. The number of copies of this document must be equal to the number of participants in the procedure. Based on the measurements taken, the payment for hot water is recalculated or not according to the tariff for cold water.

70−80°C: at this temperature the disinfection process occurs;
66°C: Legionella dies within 2 minutes;
60°C: the bacterium dies in 22 minutes;
55°C: bacteria are destroyed in 5-6 hours;
20−45°C: temperature of active reproduction of bacteria;
Below 20C the bacterium does not multiply.

Hot water does not meet standards

After temperature measurements have been taken and the temperature standard for hot water supplied to the living space is not met, you should complain to the relevant 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 lukewarm, and sometimes cold, which is unacceptable;
It also happens that the water from the tap comes out of 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, for which the culprits must answer. When real estate owners are affected by such problems, they need to call the employees of the management organization or the HOA to find out and eliminate the causes of the violations.

It should be borne in mind that all apartment owners have the right to demand not only the elimination of the preconditions, and in the shortest possible time, but also to recalculate utility costs for hot water, and when there is no water in the water supply, not even pay for this service.

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

Accepted standards

Cold water supply is a set of measures that are aimed at providing consumers with water in the required volume. Today, a person’s country stay in a private household can be just as comfortable as in a city apartment.

One of the main components of comfortable living is the availability of high-quality engineering communications, including a water supply system. Currently, such systems must comply with all established regulations and sanitary standards.

A standard urban plumbing system is represented by:

a pipeline consisting of risers and supply pipes;
the entrance of supply pipes into the building;
valves of shut-off, mixing, regulating and water-folding types;
water metering units;
filtration devices;
pumping equipment.

In private households, it is also possible to provide yourself with water by installing your own autonomous water supply system, presented by:

installation of pumping equipment for a water intake source in the form of a well or borehole;
installation of a water tank designed to ensure uninterrupted water supply and reduce the load on pumping equipment;
arrangement of a water treatment system, including filter components and softeners;
installation of piping inside the house.

The cold water supply standards specified in CHiP stipulate the supply of drinking cold water through pipelines that are made of materials that fully comply with sanitary standards. Most often, a pipeline made of modern and durable polypropylene or metal-plastic is used.

The temperature of the water in the system may also vary slightly depending on pressure indicators and quality composition.

According to the technical regulations specified in CHiP, a total interruption in the supply of cold water supply is allowed for no more than eight hours over the course of one month, as well as four hours at a time.

The amount of heat in the water supplied by the cold main is not decisive in assessing the comfort of living and in creating sanitary conditions.

For apartment buildings, CHiP specifies pressure indicators inside the cold water supply circuit - over 0.03 MPa or 0.3 kgf/sq., but not higher than 0.6 MPa or 6 kgf/sq. The same parameters for a water column should not be less than 0.1 MPa or 1 kgf/sq.

Building codes

In the Housing Code of the Russian Federation, in the decrees on pipelines and sewerage, it is stated that those who periodically pay rent for water resources should receive an amount of the resource that will be sufficient for a person’s comfortable living. SNIP states that the composition of the liquid must be safe. And for the liquid to be suitable for drinking, the water supply must meet all sanitary standards. And if its supply in the house is turned off for more than 4 hours in a row, this is a violation. You can make such an application to the court by attaching the necessary documents. This decree can also be found in the water supply rules of SNIP.

A little about the water supply system

The physical parameters of water are also influenced by the technical characteristics of the entire system, which vary depending on the installation method and location.

The city water supply system consists of:

Pipeline, it consists of risers and conductive pipes.
Entrance of conductive pipes into the house.
Certain types of fittings (water intake, mixing, shut-off, control).
Water meter units.
Pumps.
Filters of various types (reverse osmosis, cartridge, flow, jug).

In private households, the water supply system is presented differently:

Well, well, water tower.
Pump.
A container for permanent storage of liquid, this will ensure uninterrupted supply and allow the pump to last longer.
Various filters for cleaning.
Piping.

The temperature parameter of cold water in the tap depends primarily on the time of year and region of residence. So in cities that take water from the Volga, the temperature is 25-27 degrees Celsius, and in places where rivers, lakes or reservoirs have a different temperature, the water will be colder or warmer. It varies from 15 to 27 degrees. In winter it is lower, reaching 3-5. It is worth noting that in the pipes through which water reaches the house, the heat may be less (minus 3-4), this is due to the fact that the pressure in the pipes reaches 10 atmospheres, and the crystallization temperature of the liquid decreases with each atmosphere.

According to the standards, the physical parameters of cold water in the tap are acceptable within 4-20⁰C. These standards should be established by housing and communal services or other local authorities; all standards are only recommendations. Exact indicators for 2020 have not been established, since they may change according to SanPin and SNiP standards depending on the time of year and place of residence. Thus, the degree of warmth of water in autumn can be 10⁰ C in September, and 5-6⁰ in October. In fact, the approximate temperature is 9 degrees. If water is supplied by a private company, then the heat is set according to their regulations within the recommended values.

You can independently find out the temperature of the water in your apartment, it should be 9⁰ C. For an accurate measurement, take 2 containers, one larger and the other smaller, but higher. Pour cold water into a large container and place it on the bottom of the sink, then collect the liquid in a small container and place it in a larger one so that the stream flows into the larger container and does not fall into the smaller container. Then place the thermometer in a smaller container and wait 5 minutes.

Residents of Khakassia often complain about the temperature of hot water from the tap in their apartment. Sometimes it’s cold, sometimes it’s almost boiling water. But the water must have a certain temperature, which is enshrined in Russian legislation. And if the requirements are not met, then residents can demand a recalculation for a poorly rendered service. First things first.

What temperature standards are set?

If we refer to the Rules for the Provision of Utilities (SanPiN 2.1.4.2496-09 “Hygienic Requirements for Ensuring the Safety of Hot Water Supply Systems”), then the permissible limits for the temperature of hot water in an apartment are from +60 °C to +75 °C.

In this case, according to the rules (Government Decree No. 354), deviations are allowed:

— at night (from 0:00 to 5:00) the permissible deviation should be no more than 5 °C;

— during the day (from 5:00 to 0:00) the deviation should not exceed 3 °C.

The water that comes from the tap is brought to the required temperature by equipment installed in the basement of the house. The management organization is responsible for this. From a thermal power plant, water flows through large main pipes, usually much hotter than through the pipes in the house. In winter, its temperature can reach +130 °C. The water temperature that the thermal power plant must produce is also regulated by the rules, and the temperature schedule is approved by the city administration.

Where to go if there are deviations from the norm?

For all problems in the house and apartment, residents contact their management company (MC) or HOA. The quality of hot water is no exception. High or low temperature is just one of the reasons for the complaint. The management company should also be concerned if the water has an uncharacteristic color (smell, taste) or is completely absent.

A specialist from the management organization must come, measure the water temperature and draw up a report, which the resident signs. By the way, you can leave your comments in the act if, for example, you do not agree with what the representative of the Criminal Code wrote.

If the resident’s complaints are confirmed, utility workers are obliged to find the reason and fix everything within an average of one to seven days, depending on the complexity of the work. During non-compliance with water standards, recalculation is made at the request of the resident. In case of refusal to recalculate, you should file a complaint against the actions of the management company with Rospotrebnadzor, the housing inspectorate or the magistrate's court.

Can you measure the water temperature yourself instead of waiting for a management company employee?

There is no need to measure the water temperature yourself. This should be done by a specialist who, based on the results of measurements, will draw up an act, which will be the legal basis for recalculation. Measurements are made with a thermometer with a scale of 100°C according to certain rules. Residents can control this process.

— Open the tap and let the water drain for about 3 minutes. This way they get rid of stagnant water, the temperature of which is traditionally lower. The stream flow should not be strong, but not weak either - you need to find a middle ground.

— Place a glass under the stream and hold it so that the liquid overflows over the edges. You cannot simply take a glass from the tap, because by the time it is brought to the table where the thermometer is placed, the water will have cooled, and the reliability of the measurement will be questionable.

— The thermometer is lowered into the container closer to the center.

— They wait until the degrees on the device stop increasing and record the result.

Why does the water temperature have to be exactly this?

Temperature control is extremely important for a number of reasons. Fresh and warm water is an excellent place for bacteria to grow and live. It would seem that the conclusion is obvious: it is worth supplying hot water at a high temperature. But too hot water can cause burns.

That’s why SanPiN sets a temperature threshold. The water should not be below a temperature of +60...+75°C, at which bacteria die. But it should not be higher, so that residents do not receive serious burns.

A water temperature of more than +65°C burns the skin in 2 seconds, a temperature of +65°C burns the epidermis in 5 seconds, a water temperature of +55°C burns the skin in 90 seconds. During this time, a person will have time to react and not get burned. That is why you should not use hot water in its pure form, but rather turn it on together with cold water, reports sibgenco.online.

Calculation of water heating costs

I usually fill the kettle with water at room temperature 20°C to the 1 liter mark and always bring it to a boil (up to 100 degrees). Kettle power 2 kW. The simplest calculation shows that boiling will cost approximately 0.1 kWh (kilowatt hours) of electricity, 3 minutes of time, and, according to Moscow tariffs, fifty kopecks of money.

To calculate the consumed electricity, you must indicate the temperature of cold and hot water, as well as its volume (mass). You can indicate the efficiency of the heating device if you know it. If you set the efficiency to 100%, the calculation will show only the useful power spent on heating water. When indicating the real efficiency, the calculation will give the total power consumed from the network.

Recalculation if the temperature does not meet the standards

If the temperature of hot water at the time of collection was only 40 degrees, then payment for its consumption must be made at the rate for cold water. In order for recalculation to be made, it is necessary to measure the water temperature .

First, you should contact the dispatch service of the management company or housing and communal services. It is mandatory to record an application for water temperature below the required level in writing, indicating the application number, the time of its acceptance and the name of the dispatcher. Perhaps the drop in water temperature occurred due to a technical malfunction of the pipeline or for some other known reason. In this case, the dispatcher is obliged to notify about the emergency mode and the timing of troubleshooting.

Features of measurements

Draining the water should take at least two to three minutes.
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 discrepancy with SanPiN, for this there is an article in the Code of Administrative Offenses, it reads “Violation of standards for the provision of utility services” and implies a fine .

Checking temperature and quality

If, to control water pressure, people install pressure gauges and pressure reducers in apartments themselves, then no one bothers to control the temperature of hot water.

Read: Plumbing in an apartment building

To improve the quality of water, coarse filters (required) and fine filters (optional) are installed in the water supply system.

Water quality control can be done in any independent laboratory that has the necessary certificates.

Temperature according to GOST

The qualitative composition of all water used for household and drinking needs must fully comply with the current State Standard, and for production purposes it is regulated by technological requirements.

The temperature regime of cold water in the GOCT tap is not regulated, but you need to remember that these indicators directly depend on the time of year.

This feature is associated with the temperature of the water at the source of water intake, as well as the temperature indicators of the soil at the level of the water pipeline.

In the main water supply, the water temperature can even be negative, since under conditions of high pressure inside the system, the process of freezing the liquid is noticeably slowed down.

It should be noted that in residential buildings and industrial facilities, where it is not possible to fully meet the needs of all consumers through sources of drinking water supply, the presence of technical and economic feasibility, as well as approvals from the SES, makes it possible to supply non-drinking water to premises with some basic plumbing fixtures.

Despite the fact that temperature standards for cold tap water are not provided for by regulations, local recommendations of service organizations often set parameters within 4-20 ° C.

In winter, some apartments can be extremely hot, while others, on the contrary, are very fresh. The temperature standard in the apartment during the heating season must be regulated by the management company.

Hot water in an apartment or house is no longer a luxury, but a common necessity. In our new apartment building, the hot water is sometimes not hot at all, but warm, which causes fair indignation among the residents and complaints to the Management Company. Hot water is more expensive, so it is more profitable for us to dilute it with cheaper cold water to obtain the same final temperature. But is it only worth fighting for economic gain? Let's figure out what the tap water temperature standards are based on.

The laws of many countries, including ours, establish safety standards for various services, including hot tap water.

Two main factors influencing the choice of water temperature are bacterial growth and possible burns . These two factors act in opposite directions. On the one hand, the water temperature should be such that harmful bacteria are killed, on the other hand, the temperature of hot water should not lead to burns (especially in children's institutions and hospitals).

One of the most dangerous bacteria is Legionella. Legionella bacteria is a gram-negative rod up to 3 microns in size. The natural habitat of the bacterium is fresh, warm water.

Very often, these bacteria are bred in air conditioning, heating, and humidification systems. Legionellosis is a disease of large cities in industrialized countries. The disease is very serious, leading to complications. An outbreak of Legionella pneumonia was recorded in the Middle Urals in July 2007 in Verkhnyaya Pyshma. The infection entered the apartments through the hot water supply system due to violation of the requirements for flushing pipes and draining water. More than 160 townspeople ended up in hospitals, 5 people died. Also, an outbreak of Legionella pneumonia was recorded between November 22, 2011 and May 22, 2012 among tourists vacationing at the Calp Hotel in Spain; 23 cases of Legionnaires' disease were recorded, 4 of which were fatal.

Effect of temperature on legionella bacteria

70°C – 80°C Disinfection area

66°C Legionella kills in 2 minutes

60°C Legionella kills in 32 minutes

55°C Legionella dies in 5-6 hours

20°C – 45°C Legionella multiplies intensively

20°C and below Legionella does not reproduce

Based on the data presented, to neutralize water, it should be heated to a high temperature. However, if the water temperature in the tap exceeds 50 °C, you can get burns to the skin surface . At temperatures above 70 °C, a deep burn occurs.

Effect of water temperature on skin

65°C partial skin burn in 2 seconds

60°C partial skin burn in 5 seconds.

55°C partial skin burn in 15 seconds.

50°C partial skin burn in 90 seconds.

Thus, in tanks for heating and storing hot water, the temperature must be high in order to neutralize the water. At the same time, water should not be supplied to the consumer very hot, in order to prevent skin burns in case of accidental shutdown of cold water. The standards that are established for places of mass consumption of water (hotels, schools, hospitals, etc.) are approximately the following: shower 41°C, washbasin 41°C, bath 44°C. To ensure this, special thermostatic mixers are used. It should be noted, however, that most cases of legionellosis infection were observed in people who stayed in hotels.

Another option is not to use faucets, but to mix the water flowing from two taps (cold and hot) in the sink or bathtub. In this case, you can supply very hot water to the tap. Such systems can often be seen in English houses.

As a rule, in Russia, very high temperature water is supplied to residential buildings with a centralized water supply. But it is not uncommon, especially in new homes, for water pressure and temperature to decrease, which can certainly lead to the development of harmful bacteria in the pipes. Therefore, the problem with the temperature of hot water in our (and in other) houses is a serious problem that is associated not only with overpayments for housing and communal services, but also with the health of the residents of the house.
