What to do if lukewarm water comes out of a hot tap? Why does water flow poorly from the faucet? Hot water takes a long time to heat up, so why complain?

Current legislature

Legal standards set out very clearly the requirements for hot water supply in multi-apartment residential buildings. They are set out in two main regulations.

approved by Government Decree Russian Federation No. 354 of 05/06/11 “Rules for the provision utilities owners and users of premises in apartment buildings and residential buildings." Appendix No. 1 – “Requirements for the quality of public services”;
Sanitary and epidemiological rules and norms approved by the Resolution of the Chief State Sanitary Doctor. Abbreviated as SanPiN 2.1.4.2496-09 “Hygienic requirements for ensuring the safety of hot water supply systems.”

Important! According to the specified regulations, hot water supplied to housing must meet the following requirements:

be no lower than + 60 and no higher than + 75 degrees, regardless of the heating system installed in the residential building;
To measure the temperature of the supplied water, you must leave the tap open for three minutes and only then take measurements.

Depending on the time of day, the following permissible temperature deviations are possible:

from 0.00 a.m. to 5.00 a.m. - no more than 5 degrees in one direction or another;
from 5.00 am to 00.00 am - such a deviation is permissible by no more than 3 degrees.

If water is supplied at the appropriate temperature, then consumers pay its cost at the full rate.

If the water temperature does not meet the stated requirements, then you should pay based on the following:

at temperatures below 40 degrees, payment is made as for cold water. However, for this it is necessary to record this fact. Draws up a corresponding act with a call from a representative of the heat supply organization;
for water supply whose temperature is above 40 degrees, but below 60, the payment tariff is reduced by 0.1 percent for each hour of water supply at this temperature. Again, this fact must be recorded with the drawing up of an act.

For what reasons can hot water be lukewarm?

The supply of hot water to multi-storey residential buildings, which does not correspond to the established temperature regime, can occur for various reasons.

Please note!

The first is the fault of the heating supply organization, which does not heat the water to the established temperature conditions.

The second is the design flaws in the installation of the hot water supply system. As a result, there is no sufficient circulation of hot water, and residents have to drain the water that has cooled overnight until hot water flows.

Thirdly, perhaps the reason is in the pipe itself through which hot water flows. For example, she hid herself on the floor below. Everyone who lives below has hot water, and those on the upper floors have warm water. To rectify the situation, you must contact the management company, which is obliged to carry out the necessary checks and eliminate the blockage of the pipe.

Fourthly, incorrectly installed devices in the path of water movement. The same principle as for clogging. Someone reinstalled the faucet and boiler and cut off sufficient water flow through the riser. As a result, everything is fine with him, but his neighbors suffer.

Fifthly, the residential building was the last one on the hot water supply line. That is, in a dead-end zone. It is further aggravated by the fact that the hot pipeline is not looped, but simply ends in the house. Then the problem of hot water will be constant.

Since the previous houses will take away all the hot water, and it will reach the dead-end volume already cooled. That is, not heated to the required temperature. The only way out of this situation is to loop back the hot water supply line. This is almost impossible, as it costs big money

. These are design costs. There can be only one way out - installing an electric boiler and refusing hot water supply.

Also, one of the reasons for the lack of hot water supply may be an accident in the supply system outside the house. In this case, all you have to do is wait until the breakdown is fixed.

How to measure water temperature yourself

Before calling representatives of the heat supply organization, housing office, or management company regarding the temperature of the hot water, you should make sure for yourself what indicators the water has.

Attention! To do this, you need to do the following manipulations:
fully open the hot water supply tap and drain it within three to five minutes;
fill a container with tap water;

Based on the results of independent measurements, make a decision whether or not to call representatives of the relevant services to draw up a report.

Attention! Our qualified lawyers will assist you free of charge and around the clock on any issues.

What to do if the hot water is not up to standard

Having established by independently measuring the temperature that the water supplied to the apartment does not meet the standards, it is necessary to take steps in accordance with Government Decree No. 354, which establishes the rules for the provision of utility services.

The consumer's action algorithm should be as follows:

call or send a written message to the dispatch service of the heating supply organization that the temperature of the supplied water does not meet the standards. All types of citizen appeals, regardless of their form, are registered. In this case, the consumer is obliged to indicate his last name, first name, patronymic, address of residence, day and time of measuring the hot water temperature;
if the appeal was oral, then the dispatcher is obliged to inform who exactly received the citizen’s message, and under what number it is registered in the book. If a written document was submitted, then on the second copy the dispatcher puts a mark on the date of acceptance of the request and the number in the incoming correspondence book;
if there are any problems with the hot water supply due to the fault of the company, the applicant must be notified about this, and the cause of the breakdown and the estimated time of elimination must be given;
if the reason for the supply of hot water with a low temperature regime to the heating supply organization is not known, the time for representatives to travel to take measurements and draw up a report must be agreed upon. Paragraph 108 of Resolution No. 354 sets a deadline for this - no later than two hours after the message, the check must be carried out. However, the parties may agree on a different time;
After representatives of the heat supply organization visit the applicant’s place of residence, appropriate measurements are taken and a report is drawn up. This document confirms or refutes the facts stated in the consumer’s application. It may happen that the temperature will improve before the representatives arrive;
the inspection report is drawn up in several copies. One for the consumer and thermal workers, and one copy for other departments if they took part in the departure based on a citizen’s report.

ATTENTION! Look at the completed sample complaint to the management company regarding the non-compliance of hot water with standards:

If the consumer is not satisfied with the data reflected in the act, he can insist on an examination. In this case, a second check is carried out, but with the participation of a specialist.

Such studies are paid for, and all costs will be borne by the consumer. If the fact of supplying hot water below the established temperature conditions is confirmed, then the heat supply organization will be obliged to compensate for the costs incurred.

How to request a recalculation

After the consumer has received a report confirming violations in the hot water supply, he applies for a recalculation. He submits such a document to the management company if it collects payments or to the heat supply organization if the payment goes directly to them.

Remember!

The period for which recalculation must be made is determined from the date of documentary confirmation of the fact of the violation and ends on the day when such violation was eliminated.

Paragraph 112 of Government Resolution No. 354 determines the day for eliminating the identified violation as follows:
the date when the consumer reported to the dispatch service that there were no more problems with the hot water supply;

the date of the final inspection, based on the results of which a report was drawn up with the signature of the consumer stating that hot water is supplied at the required temperature.

Until the consumer reports that the problem has been corrected, or a re-inspection is performed and a report is drawn up, the period for providing poor-quality service cannot be completed. Therefore, the consumer has the right to demand further recalculation.

The management company, housing office or heat supply organization do not have the right to refuse the consumer to measure the temperature of the supplied water. Moreover, they do not have the right to refuse recalculation if cold water was supplied instead of hot water.

If they do this, the consumer has the right to file a complaint with the prosecutor's office, the housing inspectorate, or file a lawsuit in court.

Where can I complain? Hot water supply that does not match established standards

, can be caused by both actions and inaction on the part of the management company, housing office, or heat supply organization.

As practice shows, service consumers prefer to first report the problem and insist on its elimination. When positive result

The initial authority they choose is the head of the heat supply organization, and then they involve such bodies as:

state administration or local government;
district prosecutor's office;
state housing inspection;
territorial division of Rospotrebnadzor.

As a last resort, a claim is filed with the court at the place of residence.

ATTENTION! Look at the completed sample complaint to the Prosecutor's Office against the Criminal Code regarding low hot water temperature:

Watch the video. The hot water temperature does not meet the standards:

How to write a complaint addressed to the head of the company

Complaints filed by consumers to various authorities do not have a uniform form. And the current legislation does not impose any requirements for the preparation of such a document.

The law determines that in order to protect his violated rights, the consumer has the right to file a complaint with the appropriate response authority.

As practice shows, a written complaint is presented in free form.

However, for the sake of completeness, it contains the following data:

name of the organization or institution to which the document is submitted;
position, surname and initials of the manager to whose name the complaint is addressed;
Name settlement, name of the street, number of the building where the specified addressee is located;
last name, first name, patronymic and place of residence of the citizen who is applying;
name of the document “Complaint”;
date of conclusion of the contract for hot water supply;
the obligations of the parties are to supply water at the appropriate temperature for the supplier and timely payment for the consumer;
the essence of the violation, when, by whom and how the fact of a violation in the hot water supply was recorded;
legal grounds for filing a complaint;
stated requirements;
Attached documents;
date, signature, surname and initials of the consumer.

Attention! The complaint is drawn up in several copies, one for each addressee, if there are several of them, and one remains with the applicant. The document is submitted to the office of the hot water supplier for signature and registration, which is noted on the consumer’s copy.

If they refuse to accept the complaint or do not want to register it, it is better to send the document by mail. To do this, use a registered letter with a list of attachments and a notification of delivery.

Time limits for consideration of a complaint

To consider a complaint filed by a consumer, the supplier is given certain period. It may be specified in an agreement concluded between the parties or indicated in a consumer complaint.

If such a period is not provided for in the contract and is not specified in the complaint, then a 30-day period for response is usually accepted.

Instead of a complaint, the consumer can file a claim of similar content with a requirement to change the terms of the contract or terminate it.

In this case, two weeks are allotted for consideration of the claim. If the document was sent by mail, the time required for postal document circulation should be taken into account.

Application to the State Property Committee

An effective way to resolve the issue of hot water supply would be a complaint addressed to the state housing inspectorate. At the same time, what is stated in the document must be supported by references to the requirements of SNiP and SanPin, measurement reports drawn up by specialists or invited experts.

The redneck should be concise and as informative as possible. Do not contain insults or obscene statements.

Please note!

As required details, the document must contain:
surname and initials of the head of the state housing inspection;
address of the location of the institution;
last name, first name, patronymic and address of residence of the consumer of hot water supply services;
if the complaint is collective, then the details of all residents who initiated and signed the document are indicated;
title of the document “Complaint” or “Collective Complaint”;
the essence of the violation, when, by whom it was recorded, what standards were violated;
what measures were taken to resolve the conflict peacefully;
reaction of the heat supply organization;
legal grounds for filing a complaint with the housing inspectorate;
requirements;
copies of the attached documents;

date, signature and transcript of the names of those who applied. Using ordinary tap water, the consumer may be in for a surprise: instead cold water

, he gets hot.

Why is this happening The most common reason for having hot water instead of cold is the effect pressing hot water with cold due to the fact that the pressure of hot water (6 atm.) in the water supply system of the house is greater than the pressure of cold water (4 atm.), and there is no check valve.

Therefore, it is advisable to take care of it yourself, because this may contribute to the fact that the sucker will one day scald his hands. There should be a valve on every floor. Check valve - a device that prevents the flow of water into via pipeline. That is, water cannot go on its own or under pressure into the pipeline from which it came. Instead of installing 2 valves, you can install new type water meters on the hot and cold water pipes, which are equipped with these devices.

Where to complain and against whom

If the installation of water pipes in your apartment is carried out correctly with the installation of check valves, then the appearance of hot water from an empty tap is unlikely, and if this is observed, then there is a problem one of the neighbors next door.

The owner of the apartment must establish in which apartment the problem is located, since it is the owner of the property who is responsible for repressing in the event of a lack of check valve because the area of responsibility of the HOA or management company ends after the shut-off valve (riser and shut-off valve).

The maximum you can do is complain to the control room of your management company or HOA.

Which devices are to blame for oversqueezing?

Any plumbing fixture can cause squeezing if a non-return valve is not used, because almost every home uses a dishwasher, boiler, washing machine.

Most often, consumers use a one-handed mixer. Belongs to the cartridge type. The main working part has 3 holes for supplying cold and hot water and draining mixed water. Mixing of water is carried out by blocking the holes for cold and hot water to the required amount with the mutual movement of two ceramic plates, adjustable with a handle. The tightness of the system is ensured by careful fitting and tight connection of these plates. As the mixer wears, the plates may rise in relation to each other, forming a gap, and in this case, a squeezing effect may occur.
The same situation is possible when using a standard mixer, which has 2 taps and a shower, if the tap-shower switch is set to the intermediate neutral position when the taps are open. In this case, if a check valve is not used, water will circulate in the system due to the pressure difference in the hot and cold water supply pipes supplying the mixer. Hot water will be mixed with cold. This phenomenon is accompanied by the noise of flowing water, which is an additional diagnosis of overflow.
Another device that may cause the phenomenon of squeezing is a bidet (hygienic shower) with a mixer and an additional button on the shower head that turns off the water without turning off both taps. If, after hygienic procedures, you do not close the faucet valves, but only release the button, then water will not flow into the bidet, but there will be an admixture of hot water in the cold water system, which can flow out when the cold water valve is open, including in a neighbor’s apartment. By constantly closing the bidet faucet valve, you can avoid a situation where there is either cold or hot water in the cold water tap.
The source of the problem may be the boiler. In the absence of a check valve, hot water from the boiler will flow into the cold water riser due to a decrease in pressure when one of the neighbors uses cold water, or if they forget to close the taps at the inlet or outlet of the boiler when the tap on the hot water supply riser is open. If the boiler is constantly connected to the network, then in the event of an overflow, hot water from the boiler will be in the cold water supply pipes, and, as a result, electricity costs may increase significantly.

What to do

Check the cold water meter. It should not turn in the opposite direction. If it is still spinning, then you need to close the tap on the riser; if the movement has stopped, then you definitely have a problem and you need to find a mixer or device that presses hot water.

If there are no water meters, turn off the tap on the hot water riser, open the cold water in the mixer and wait until the hot water stops flowing. Then close the mixer, open the hot water tap on the riser and determine with your hand whether the cold water outlet is heating up. If the problem is in your apartment, then the outlet will heat up, but if it’s at your neighbors’, it will remain cold.
To determine which neighboring apartments are causing the leak, turn off the hot water at the riser. Then open the cold water tap on the mixer; when the hot water stops flowing, go to the riser and determine with your hand whether the riser is heated in the upper or lower part of the tap, which will show you the source of the malfunction on the upper or lower floors.

If the problem is in your apartment, and you do not leave the faucet valves in an intermediate position for a long time and constantly close the valves on the bidet, and hot water continues to flow from the cold tap, then the cause is a faulty faucet. Most often this is an old, corroded gasket whose service life (7 years) has expired or a bad valve seal. The mixer itself may be faulty. Replacing faulty parts yourself or with the help of a plumber will eliminate the problem..

> What to do if lukewarm water flows from a hot tap?

Hot water supply is one of the most common problems in the field of housing and communal services. It is not uncommon for utility payers to receive lukewarm water instead of hot water. Thus, the rights of the payer are violated. What to do in such a situation?

Legislation clearly regulates minimum and maximum water temperatures. Deviations within 3-5 degrees are allowed, but no more. Hot water should be between 60 - 75 degrees. According to standards, a water temperature of less than 60 degrees is already considered warm. It is not for nothing that these figures were taken. The fact is that at temperatures below 60 degrees, infectious pathogens multiply and pose a danger to humans. Water temperatures above 75 degrees are also not normal; very hot water can cause burns. Cold water also has its own standards. The cold water temperature should be between +4 - + 20 degrees. Temperature + 20 and below destroys various infections. The above standards of hot and cold water are taken not only for convenience, but also for protection against infectious pathogens.

If the water temperature standards are violated, first of all, you need to contact. You can file a complaint over the phone or directly at the company's office. The company will send its specialist (plumber) to measure the water temperature. The help of a specialist is needed to document the fact that the water temperature does not match. It should also be noted that you do not need to measure the water yourself. The received data will not have legal force.

After checking the water, the plumber will draw up two reports. One will take it to the company, the other will leave it for you. If your fears are confirmed, and instead of hot you get lukewarm water, then in this case, you have the right to a recalculation. To do this, you need to take a water measurement certificate, documents for home ownership and contact the service provider again. The discount on water payment will depend on the discrepancy in water temperature. If the water temperature is below 40 degrees, then you can pay for hot water at cold rates.

Next, specialists from the management company will determine the reasons for the violation of water temperature standards. In fact, there can be many reasons:
- cracks, growths, depressurization of pipes;
- poor quality plumbing;
- violation of operating rules by neighbors. For example, installing a heated water floor;
- mistakes of the construction company.

Once the causes are identified, the company must eliminate them. In most cases, the cause is wear and untimely repair of the water supply system. The company that provides the utilities is responsible for it. The company will do the repairs. Also, a decrease in the temperature of hot water may be due to a builder who installed the water supply incorrectly. In this case, Management Company must sue the builder. Or maybe you yourself are to blame. Partitions in plumbing may break, and instead of hot water, you will get lukewarm water. Then you will have to change the plumbing yourself.

There are times when the utility company does not respond to complaints and does not want to recalculate water prices. Then you need to register an appeal to the company. All complaints must be in writing. Documents will be needed if the case goes to court. If the company does not provide a representative for measuring water temperature, you need to contact an independent specialist. The drafted act will have a very important role in the legal process. It is imperative to file a complaint with the State Housing Inspectorate for the inaction of the service provider. If all attempts to resolve the issue peacefully have failed, then you need to go to court. There is a high chance of winning the case. There are precedents. You just need to prove in court the inaction of the utility company.

Water / Cold and hot water meters

The situation is familiar to almost everyone: in the morning a barely warm liquid runs from the hot water tap, which you have to use to wash your face. If you have time, you can open the tap and drain cool “hot” water for 15-20 minutes until it reaches the desired temperature.

However, if the apartment has a hot water meter, cubic meters of lukewarm water poured down the drain will cost the owner of the living space the full cost of heated water, which is 4-6 times more expensive than cold water.

It often happens that “hot” water is not too different in temperature from “cold”. And instead of mixing hot and cold, you leave only the hot tap open. Lukewarm water flows from the faucet. And it stands like hot water.

What to do in such a situation? Resign yourself and overpay? And if we fight, then how exactly? Let's figure it out together.

Cold water from a hot tap: legislation

First, let's find out what the current legislation says about the requirements for the temperature of hot water supplied to an apartment building.

Requirements for the quality of hot water supply are specified in two documents:

“Rules for the provision of utility services to owners and users of premises in apartment buildings and residential buildings”, approved by Decree of the Government of the Russian Federation of May 6, 2011 N 354 Or rather, in its Appendix No. 1, which is called “Requirements for the quality of utility services”
Sanitary and epidemiological rules and regulations SanPiN 2.1.4.2496-09 “Hygienic requirements for ensuring the safety of hot water supply systems”, approved by Resolution of the Chief State Sanitary Doctor of the Russian Federation dated April 7, 2009 N 20 “On approval of SanPiN 2.1.4.2496-09”

The following follows from these documents:

The temperature of hot water in water supply points, regardless of the heating system used in an apartment building, must be no lower than 60°C and no higher than 75°C
Before determining the hot water temperature, the water is drained for no more than 3 minutes.

Permissible deviation of hot water temperature:

at night (from 0.00 to 5.00 hours) - no more than 5°C;
in the daytime (from 5.00 to 00.00 hours) - no more than 3°C

The requirements for the quality of hot water supply also imply the terms of payment for this utility resource if the water is not at the right temperature.

Firstly, the hours in which the supply of hot water with a temperature of less than 40°C is recorded are summed up. And during this period of time, payment for consumed water is made at the cold water supply tariff.

Secondly, if the temperature is below the legally established 60°C, but above 40°C, then the charge for hot water is reduced.

The mechanism is as follows: for every 3°C deviation from the permissible deviations in hot water temperature, the amount of payment for water in the month in which the specified deviation occurred is reduced by 0.1% for each hour when such a decrease was recorded.

Why (physically) hot water turns out to be lukewarm?

Having understood the legal requirements for permissible hot water temperatures, we will consider the reasons why these requirements may not be met in your home.

First of all, these may be problems directly in your home. For example, design flaws in the hot water supply system (there is no circulation of hot water and in order for residents of the upper floors to get hot water in the morning, they need to drain the water that was in the risers all night and had time to cool down).

Or incorrect adjustments of the hot water supply system. Simply put, for some reason the building management organization does not sufficiently heat the water that goes to the apartments.

Alternatively, the circulation of hot water may deteriorate due to a clogged pipe on the floor below (for example, they cut in a “goose” to hide the hot water pipe in the wall of the bathroom and thus free up space for the bathroom).

Or - due to improper installation of an electric boiler (bidet, mixers, etc.) in one of the apartments along your riser.
In all these cases, solving the problem at one cost or another, but it is possible with the help of pressure on the management organization of your home.

More serious in its consequences is the option when hot water does not have the required temperature for external reasons not related to your home. For example, when your house is the end of the hot water supply line. Those. First, several high-rise buildings up to you take hot water. And only then the water pipeline goes to your house. And if this line is not looped, then it turns out that in your dead-end branch the hot water cools down by the morning (and sometimes it does not warm up to the required temperature at all).

And in in this case The organization responsible for managing your home, no matter how willing it is, will not be able to ensure that problems with hot water are eliminated. Work on relaying hot water supply lines (a) is too expensive, (b) is carried out in an area where your management company cannot manage.

Exactly the same can be said if hot water is not supplied to the house due to an accident (destruction of the water supply) outside the home networks. The management organization cannot eliminate violations. This is a matter for the heat supply organization and municipal authorities. As practice shows, it is much more difficult to “put pressure” on them.

What to do if the hot water is lukewarm?

So, what should you do if lukewarm water flows from your hot tap? First of all, you need to inform your management organization about this, call its representative to the apartment so that he can take water measurements and draw up a corresponding report in your presence.

If measurements show a temperature below the established standard, then starting from the day the act is drawn up, the requirements of the law to reduce water charges come into force (which we discussed in the chapter on legislation). If, for example, it is determined that your water temperature is below 40°C, then you will pay for the cubic meters calculated by the hot water meter at the same rate as for cold water. This will continue until the next report is drawn up - on eliminating violations of the requirements for hot water temperature.

What to do if you called the control room by phone and didn’t even write a statement, but there was no response, you ask? Or was the act drawn up, but the water remained cold?

In this case, you need to contact the housing inspectorate of your region (locality). Inspections usually respond to such requests and they have effective leverage over the management organizations of apartment buildings. To begin with, an order may be issued, then a decision on a fine, transfer of the case to court, revocation of the license, etc.

In addition to the housing inspection, it is also possible to contact the prosecutor's office and directly to the court with a statement of claim. Courts consider such cases and make decisions in favor of citizens. In addition to the obligation to provide the apartment with hot water at the required temperature, utility workers are also forced to pay compensation for moral and material damage.

If you want to delve into the details of the process, you can look, for example, at this decision of the Kirovsky District Court of the city of Perm in a case involving cold water from a hot tap.

But here, of course, you need to understand that when the matter reaches the level of litigation in court, there will not be a quick solution to the problem. And the result is not guaranteed. Even if the court decides in your favor.

As mentioned above, the solution to the problem with hot water may often depend not on the management organization, but on the owner of the heating networks and hot water supply networks. Infrastructure reconstruction may also require participation and funding from municipal authorities. In general, the process will be long, nervous, and most importantly, you will be without hot water all this time.

Water heater as a way to solve the problem with cold hot water

So it turns out that perhaps the most effective way The “struggle” will be the transition to autonomous hot water supply. In other words - put electric water heater(boiler). Let's consider this issue from a practical point of view.
The heater can be flow-through or storage. It is better, as experience shows, to use a cumulative one. This is a container with a volume of up to 200 liters with a heating element (which provides heating of water) inside and a layer thermal insulation material(which keeps the water from cooling) outside.

The unit looks quite aesthetically pleasing. Thanks to the thermal insulation layer, which prevents the water from cooling, it does not consume much electricity.

As calculations show, if the consumption of hot water is not too active, heating water in a boiler turns out to be comparable in price to centralized hot water supply. But, of course, you won’t be able to pour hot water from the heart - the water heater’s capacity is limited, and if you have drained all the water (for example, the children took turns splashing to their hearts’ content in the bathroom), you have to wait until it warms up again.

An important reminder - if you do not have a hot water meter in your apartment, then when installing a boiler, put an official plug (seal the tap) at the entrance from the hot riser. Otherwise, you will continue to be charged for hot water based on current regulations.

If you have a hot water meter, then when installing a water heater, there is no need to plug the hot water riser. Simply close the inlet valve. Also make sure that hot water from your boiler is not mixed into house system water supply

Hot water meter with temperature sensor

Finally, it is worth mentioning another way to save money on the family budget - a hot water meter with a temperature sensor.

This device takes into account separately the flow of really hot water (whose temperature corresponds to the standard) and actually cold water (that which comes from the hot water supply riser, but in reality is slightly warm).

The principle of operation of such devices is based on the differentiation of consumed volumes of water: the volumes of hot water and the water that comes from a hot tap, but its temperature is below normal, are taken into account separately. You add the cubic meters that the meter counted in the second case to the volume of cold water consumption and pay at the appropriate rate.

An example is the Sayany T-RMD hot water meter; this is the most common device of this kind. Although there are others that are similar.

At first glance, everything looks nice - without contacting utility companies, you only pay for the “hot water” that meets the standards. However, as is usually the case, there are several “buts”.

Firstly, the recalculation of payments for hot water that does not meet the requirements of the law must occur in accordance with the requirements of this very legislation. That is, according to the procedure, with calls from a representative, “acts”, etc. The legislation does not mention automatic recalculation of readings based on the readings of the “thermal sensor”. This is the position of the utility companies and there are several court decisions that support it.

Secondly, it is worth remembering that it is not enough to install the meter; it must also be sealed and “put into operation.” This cannot be done without utility workers (employees of the management organization). Whether they will accept the meter or not is an open question. In some places they are loyal, in others they are not.

Thirdly, considering the consumption of water from a hot riser as cold, you thus shift the payment for this volume to general house needs. That is, for all residents of the house.

Fourthly, and this is the main thing! - a meter with a temperature sensor does not provide you with hot water. And this brings us back to the problem of installing a water heater.

Problem with cold water from a hot tap. Summary

So, a quick summary. Cold water from a hot tap can be a problem. And if we're talking about about problems within the house system, then it is quite possible to win. Especially if the problem is related to the system settings or its not very complex reconstruction.

If the quality of the hot water supply is low due to problems outside the home system, then you may not be able to resolve the issue. In this case, you will have to install a water heater; there seems to be no other way out.
