What is the hot water component in the receipt? Formula for calculating water heating in a housing and communal services receipt. How is the charge for hot water supply calculated? What is DHW heating? What does the abbreviation HVS DPU mean?

When paying for utilities, consumers see in receipts various abbreviations. It is important to know what stands behind these letters and where the money goes. DHW is a hot water supply service. But let’s take a closer look at what it includes and what it consists of.

Regulatory framework and definitions

Hot water, centrally supplied to consumers, in accordance with the provisions of the Government of the Russian Federation No. 354 of May 6, 2011, is one of the communal resources. A utility service is the provision of a resource to the consumer by the service provider (provider).

That is, in the case of hot water supply, the utility service is the supply of hot water of the required parameters to apartments apartment buildings, dorm rooms, enterprises and public buildings (hospitals, laundries, kindergartens, etc.).

The heating network provides services for the supply of hot water to residents, and it is also its responsibility to carry out central heating residential and public buildings.

Features of the service

The preparation of hot water for the needs of hot water supply occurs in centralized heating boiler houses, in the same place where the coolant of the heating system is heated.

Boiler rooms can be connected to a looped DHW system or be a dead-end type - designed for a group of houses or one house (for example, rooftop boiler rooms). The closer the consumer is to the source of hot water (boiler room), the better the quality of the service provided and the higher the water temperature. However, connecting to loop networks is preferable from the point of view of reliability and uninterrupted hot water supply.

The service includes:

1. Boiler room maintenance. Unlike heating, domestic hot water is provided all year round, while the boiler houses switch to summer (minimum) operating mode.
2. Trail maintenance.
3. Carrying out scheduled repair work on networks.

Water heated in the boiler room for an open (unclosed) DHW system enters consumer apartments through supply water pipes, distributed among intra-house networks DHW.

It should be remembered that hot water cannot be used for cooking due to the presence of additives in it - special additives that reduce the level of scale formation on internal walls pipelines.

The temperature of hot water for consumers is regulated by sanitary and legal standards and is +50…+65 °C. In reality, it often does not exceed +40 °C.

This is due to heat losses during the supply of coolant along routes (poor pipe insulation, gusts) or due to low temperature at the outlet of the boiler room. Boiler room operators adjust output parameters based on outside air temperature.

The service provider’s task is to provide apartments with a utility resource of appropriate quality. Sometimes the heating network justifies the poor quality of the service by the deplorable state of the networks - routes built in the last century, requiring major repairs, will not withstand temperature changes in winter time, if you maintain the parameters of the coolant at the outlet of the boiler room at the standard level.

It turns out vicious circle– many residents often do not pay for hot water due to its low temperature or refuse this service altogether, switching to water heating electric boilers. And heating network enterprises cannot produce renovation work, because the population's debt to pay does not give them an influx Money.

Bottom line

To pay or not for DHW service, if it turns out to be of insufficient quality, it is a purely personal matter. It is important to understand that if you decide to take the path of non-payment, you do not need to simply create debts. It is necessary to collect the evidence base according to the following scheme: carry out commission measurements of water temperature, send the results to the company providing the services. Be sure to receive an official response explaining the reasons Low quality services. Having collected a package of evidence, you can go to court to assert your rights.

The Moscow Housing and Public Utilities Department has published a brochure “How to understand the ENP.”

Every month Muscovites take out mailbox Single payment document (UPD) – a receipt for payment for housing and communal services. The document contains all the information about housing and communal services: tariffs, consumption volumes, charges, etc. It can be difficult to understand, and Muscovites often ask questions about what this or that column means.

What information does the EPD contain?:

1 . Full name – last name, first name, patronymic of the owner/responsible tenant.
2 . The address of the residential premises at which payments for housing and communal services were made.
3 . Barcode. Graphic image 28 digital characters. Required for paying for EPD via electronic terminals.
4 . The month for which the EPD was formed.
5 . Payer's personal code. It is this that must be indicated when paying for housing and communal services at terminals, ATMs and via the Internet.
6 . Information about the managing organization: name, address, contact details.
7 . Information about the residential premises: type of property (own or state (municipal), total and residential area, number of registered (indicated separately) preferential categories population), the date of creation of this EAP and the date of the last payment for housing and communal services.
8 . Types of services for which accruals are made.
Abbreviations used:
Cold water/hot water supply– cold/hot water supply
Drainage– Water disposal (sewerage)
CPU– apartment metering device
DPU- communal metering device
Cod. and repair.– maintenance and repair of residential premises within the social norm
Sod.and repair l.p.iz.pl.- maintenance and repair of residential premises (excess space)
Sod.and repair.re.lived.- maintenance and repair of residential premises (for those who have a second home or owners who are not registered in the apartment)
Heating main pl.- heating of the main area
Fear.– voluntary insurance
9 . Volumes of consumption of housing and communal services. Each service uses its own units of measurement: water supply and sewerage cubic meters ( cubic meter), maintenance and repair, social rent of housing - sq. m. (square meters), heating - Gcal (gigacalories), gas is charged based on the number of registered.
10 . Current tariffs per unit of service.
11 . The amount of charges for services (the product of column 9 by column 10).
12 . Information on the amount of benefits for certain types of housing and communal services.
13 . Information about recalculation. For example, recalculation for temporary absence and recalculation for services of inadequate quality.
14 . Accruals payable for the service, taking into account benefits and recalculation.

That is why the Department of Housing and Public Utilities of the city of Moscow published a brochure “How to understand the United payment document", Where accessible language tells about what information is contained in the payment document, about the procedure and method of calculation for each utility service, as well as much more useful information, necessary to “read” the payment document.

The brochure will help you understand how to correctly apply limit indices and who is entitled to measures social support on housing and communal services and what threatens malicious defaulters for debts on housing and communal services.

What is EPD

The single payment document is a kind of “calling card” of the city system of payments and charges for housing and communal services.

A single payment document is generated every month by specialists Multifunctional centers providing public services the city of Moscow (MFC) or state government institutions " Engineering Services» districts (GKU IS) and is delivered to residents before the 15th. On average, employees of the city settlement and accrual system generate about 4 million (!) payment documents per month.

When creating a payment document, a huge database is used: addresses and surnames of owners and tenants of residential and non-residential premises, a list of services and their suppliers, information about social support measures, etc. This entire array of information is being processed computer program ASU EIRTS. Several thousand specialists take part in the creation of the ENP. And all to ensure that the payment document ends up in your mailbox.

Control of EPD delivery together with residents

The city has a well-established system for monitoring the timing of delivery of payment documents. If the payment document is delivered later than the 15th day of the month, please report this to the EPD delivery quality control service.

To leave a message about late delivery of a payment document, you must fill out a form on the website of the State Public Institution “Coordination Center for GU IS” www.is.mos.ru.

ATTENTION

Some residents and management organizations have decided to make payments and charges for housing and communal services on their own. Their payment documents for housing and communal services may differ from the Unified Payment Document. The information contained in the brochure and further in the article relates exclusively to the ENP.

What do we pay for?

The services specified in the payment document can be divided into several parts. Housing services, these include the “Rent” service (payment for residential premises for the tenant), and the “Housing Maintenance and Repair” service. Utilities: hot and cold water supply, water disposal (sewage), heating, gas supply. In some areas of the capital, electricity is also included in the ENP. But in most cases, this utility service is paid for on a separate receipt. The payment document also includes other services: locking device, radio, antenna.

Rates, prices and tariffs for housing and utility services are established by the Moscow Government. Thus, tariffs for housing and communal services for 2014 were approved by Decree of the Moscow Government dated November 26, 2013 No. 748-PP.

The cost of services classified as “other” is determined by a civil contract and is not regulated by the Moscow Government. Let's look at all the services in order.

Housing services

If a family uses housing on a rental basis, it pays for the rent, as well as the maintenance and repair of the living space. The rental fee is calculated based on the area of ​​living space and the rate established by the Moscow Government for specific type rental - social, commercial or rental of residential premises in non-subsidized houses.

Homeowners pay for the “Maintenance and Repair of Residential Premises” service.

The cost of the service “Maintenance and repair of residential premises” includes fees for the management of an apartment building (MKD), maintenance and ongoing repairs common property, work provided for in the MKD management agreement.

The amount of payment for the maintenance and repair of residential premises in an apartment building is determined at a general meeting of owners of premises in the house. If the owners have not decided on the amount of payment for the maintenance and repair of residential premises, the calculation is made at prices approved by the Moscow Government.

The Moscow government approves two types of prices for the maintenance and repair of residential premises:
- per area within the established standards(shown below), given price is subsidized by the Moscow Government and now for most Muscovites it is 17.84 rubles. for 1 sq. m.,
- for an area exceeding the established standards. This is the actual cost of services and maintenance work and current repairs, now for most Muscovites it is 24, 53 rub. for 1 sq.m.

The price per area within the established norms applies to registered residents who have the only housing. In the ENP this service is designated “sod. repair zh.p.”

The difference between the total area of ​​the residential premises and the area within the established area norm (in the EPD it is designated “construction and repair of iz. zh.p.”) is paid at the price for the area established in excess of the norm. For owners who are not registered in the residential premises or who have a second home, accrual is made at the rates for the area established in excess of the norms for the entire residential premises (in the EPD it is designated “construction and renovation of second residential premises”).

To charge fees for the maintenance and repair of residential premises, the following rules apply. For a citizen living alone – 40 sq. m. total area living space, for a family of two people, 56 sq. m., for a family of three or more people, 25 sq.m. total living space for each family member.

For example, in an apartment with an area of ​​60.3 sq. m. 2 people are registered. The established norm for a family of two is 56 square meters. m. This means that the area within the established norms will be calculated at a price within the established norm, and the excess area will be 4.3 sq. m. m – at a price per area above the norm.

Utilities: water supply

Payments for water supply can be calculated according to the readings of apartment metering devices, according to the readings of a house metering device or according to standards.

If you pay for water supply services using an apartment metering device (KPU), then the following abbreviations are used in the EPD: “HVS KPU”, “GVS KPU”, “Water drain. KPU" - cold and hot water supply according to the readings of the apartment water meter, water disposal (sewage) according to the readings of the KPU (the sum of the readings of cold and hot water supply).

The cost of water is calculated based on the volume according to the readings of the apartment metering device (KPU), multiplied by the tariff.

The payment document indicates the water consumption in the billing month according to the readings of the apartment meter. But if the KPU readings were not transmitted on time, they will be calculated based on the average monthly consumption volume for the previous 6 months.

If you pay using a home metering device (DPU), the payment document indicates the abbreviations: “HVS DPU”, “DHW DPU” and “Water drain. DPU" - cold and hot water supply, water disposal according to the readings of the house water meter.

Calculation of charges for cold and hot water for apartments where no control units are installed is carried out in accordance with the resolution of the Moscow Government dated February 10, 2004 No. 77-PP.

From the volume of water consumption according to the readings of the house meter, the volumes of consumption for all apartment appliances, the volume of consumption for non-residential premises (if the house has, for example, shops, a hairdresser, etc.), and also general household expenses are deducted, which are determined according to the readings of the meter installed at the place where water is collected for general household needs. If there is no such device, then common household expenses are accepted to be no more than 5 percent of the volume of consumption for a common household device. The resulting balance is distributed among apartments without communal housing in proportion to the number of citizens living in them. At the same time, the resulting volume of consumption per person should not exceed two standards for the consumption of utilities.

If there are neither apartment nor house meters, charges are made according to consumption standards: 6.935 cubic meters. m. cold water per person per month, 4,745 cubic meters. m of hot water per person per month, drainage 11.68 cubic meters per person per month.

Heating and gas supply

Payment for heating residential premises in Moscow, in accordance with Moscow Government Decree No. 468-PP dated September 10, 2014, is calculated based on the average monthly heat energy consumption. To calculate it, the volume of heat consumed over the previous year is taken and divided by 12 months. Then the average monthly volume consumed by the entire house is divided by the total area of ​​the house - this is how the amount of heat required to heat 1 is determined. square meter area of ​​the house. The result obtained is multiplied by the total area of ​​the apartment and the tariff.

At the beginning of each year, the management organization conducts a reconciliation of the volumes billed to the population for payment and the volumes of thermal energy actually spent for the current year. Based on the results of the reconciliation, a payment adjustment is made, which is usually indicated in the payment document in the “recalculation” column. It can be done both in the direction of increasing and in the direction of decreasing it.

In the absence of metering devices, charges are made according to consumption standards: 0.016 Gcal per 1 sq. m of total housing area.

Payment for gas supply is calculated according to the tariff for each consumer living in the apartment.

Limit indices

The maximum index of changes in the amount of payment of citizens for utility services is universal tool control over charges for hot and cold water supply, sewerage, heating, gas. Changing the fee above the limit index is unacceptable and should entail an immediate response from the authorities executive power to eliminate such a situation.

In the capital, the limit index was approved by Order of the Mayor of Moscow dated June 30, 2014 No. 542-RM and from November 1 to December 31, 2014 it is 6.5 percent. At the same time, it is extremely tolerance the value of the marginal index for a specific residential premises is 3.2 percent.

Also, in the form of formulas, the Moscow Government approved the maximum indices for changing the amount of payments made by citizens for utility services for 2015 - 2018.

Marginal Index = Consumer Price Index x Ratio + 3.5%.

In this formula, the Consumer Price Index is calculated based on the forecast of socio-economic development of the Russian Federation for the year preceding the year for which the change indices are calculated (based on the results of 9 months). The coefficient is a decreasing or increasing coefficient for the corresponding year of the long-term period, determined taking into account the forecast of socio-economic development of Russia for this year.

How to apply marginal indices?

To determine whether the increase in utility charges exceeds the marginal index, it is necessary to compare the charges for the two periods. Fee amount for any month current year must be divided by the amount of payment for December last year. The resulting value must not exceed the limit index. However, for the first long-term period (from July 1 to December 2014), the selected month must be compared with June 2014.

If the change in the amount of the fee exceeds the size of the established limit index, it is necessary to seek clarification from the MFC/GKU IS of the district, the managing organization. And if you have not been able to find out the objective reasons for exceeding the maximum payment index for utility services, you should contact the State Housing Inspectorate of the city of Moscow and the city executive authorities.

Limit indices cannot be used in the following cases.

1. In relation to one utility service.

Limit indices apply to the total payment for all utility services provided to a citizen. Those. It is incorrect to say that the increase in tariffs for any particular utility service has exceeded the marginal index.

2. To the total amount in the EPD.

Limit indices apply only to public services (hot and cold water supply, sewerage, heating, gas). And the ENP, in addition to them, includes charges for housing and other services.

3. To utilities, if the volume of their consumption changes.

In Moscow, the majority of the population pays for utilities based on readings from apartment or communal metering devices. Accordingly, the volume of consumption, as a rule, is not the same every month, so the payment amount varies from month to month.

In addition, the volume of utility services provided is affected by the increase in the number of citizens living or registered in residential premises. Some services are charged for each resident or registered person: gas, and in the absence of individual water meters, cold and hot water supply, sewerage.

4. If your eligibility for benefits has changed.

The amount of the payment depends on whether the citizen has benefits for paying for housing and communal services. When calculating payments, the amount of payment for a specific service is reduced by the amount of benefits provided to it for its payment. In case of loss of the right to a benefit or a change in its size, the citizen’s payment may also change in big side and its growth will exceed the approved index.

For convenience and ease of checking whether the increase in utility fees corresponds limit indexes The Government of the Russian Federation has developed an information tool that allows you to make the necessary calculations online.

Currently, this information tool is posted on the websites of executive authorities of the city of Moscow.

Who is eligible for benefits?

The Moscow government provides citizens with effective system social support in the housing and communal services sector. Currently, in the capital, more than 50 categories of citizens are entitled to benefits, which is significantly more than provided for by federal legislation.

Benefits are provided in the form of discounts for no more than one apartment (residential premises) based on rates, prices and tariffs established by the Moscow Government. If a consumer has the right to social support measures for paying for housing and communal services on two or more grounds, benefits are accrued on one of them.

Introduction:

Fee calculation topic utility resources one of the most difficult. For those who have not encountered the problem before, it is difficult to figure it out right away, and there seems to be no time for it.

However, let's try.

For calculations, RF PP No. 354 is used (procedure and methods for all occasions), RF PP No. 307 (only for heating and only until July 1, 2016, then RF PP No. 354 is in effect), RF PP No. 306 (standards).

The text of the documents is complex and practically inaccessible to mass payers. There is no clear system in the designation of physical quantities, which can confuse the reader; there are no names of physical quantities used in calculation formulas and explanations. It was as if they were writing for themselves. Like we know it ourselves, but others don’t need to know.

And one more initial note. Gentlemen from the management company and from the developer often show great joy regarding the “energy efficiency” of new buildings, in particular our area.

The essence of energy efficiency is strict accounting of all utility resources and measures to save them. Let's see in the course of the discussion how justified such “joy” is.

Since we have DHW system closed, that is, non-centralized, then the corresponding section of the RF PP No. 354 (Appendix 2 section IV) is used for calculations, when the production of public services, in in this case DHW is carried out by the contractor (MC) on our ITP equipment from the common property.

Regarding this very concept of “production” of hot water supply by the contractor, we will not go into details for now. This is a separate rather “murky” and controversial topic, who actually produces what and how.

Let us only note that according to RF PP No. 354, clause 54 of the Rules, it is clearly stated that fees for the maintenance of common property (ITP equipment, where the service provider heats water for hot water supply) are charged separately. That is, “production” - operating costs for this common property are included in the payment for the maintenance and repair of common property and are not included in the calculation of payment for hot water supply.

So, what needs to be taken into account to calculate the DHW fee?

Total cold consumption drinking water(via the cold water line) supplied to heating for DHW.

The total consumption of thermal energy taken in boilers from the coolant from the centralized supply of thermal energy (heating).

Everything seemed simple. I divided the total heat consumption (heating) by the total volume of cold water that was used for hot water supply and the order. Received specific consumption heat per cubic meter of hot water.

However, our receipts do not account for the total volume of cold water and hot water separately.

But individual consumption data for DHW and cold water cannot be used due to systematic error measurements apartment meters. Therefore, the concept of ODN was introduced to eliminate this systematic error and accurately total water consumption for the entire house using a common house meter.

In this sense, RF PP No. 354 is not set out quite correctly and has long since become outdated in some places, when it is proposed to base calculations on the total readings of the IPU if there is no common house meter, but at the same time the authors of the regulatory text completely forgot about the systematic error of apartment IPU (dead zone IPU at low water flows).

According to the law “On Energy Saving...”, the first thing that must be done is to install common house metering devices, and where there is no technical possibility due to the design of the house, the technical possibility must be created by reconstructing (extension) the premises for installing utility metering units.

General household metering of utility resources is not beneficial to utility workers, which is why they sabotage the process. IN " muddy water“It’s easier to cheat.

Also, in our ITP, we do not have a separate accounting of the consumption of thermal energy, which is spent on heating the hot water supply. At least this is not clear from the content of the information given in the receipt.

But what about the super duper energy efficient ITP? Isn’t this too simple for a super duper energy-efficient ITP with “space technologies”?

Installed one total counter Cold water supply and one common heat energy meter for the entire block and are you as happy as elephants?

And according to the Law, every single house must be equipped with metering devices.

How then does our ITP differ from the usual heating unit of an old Soviet house?

Why are we being told over and over again about energy efficiency?

I want some rogue - a “money pump” under an energy service agreement to “authoritatively” declare that we need to install metering devices to increase energy efficiency.

It is already clear to us that we need a comprehensive accounting of utility resources.

Who stopped you from installing a two-channel heat energy meter? Was it difficult to install a meter to account for the flow of make-up water for the hot water system?

And if they do exist, then why are their readings not used in calculations and not indicated on receipts?

A new column has appeared in receipts for utility services - hot water supply. It caused confusion among users, since not everyone understands what it is and why it is necessary to make payments on this line. There are also apartment owners who cross out the box. This entails the accumulation of debt, penalties, fines and even litigation. In order not to take matters to extreme measures, you need to know what DHW is, DHW heat energy and why you need to pay for these indicators.

What is DHW on the receipt?

DHW - this designation stands for hot water supply. Its purpose is to provide apartments in apartment buildings and other residential premises hot water with an acceptable temperature, but hot water supply is not the hot water itself, but the thermal energy that is spent on heating the water to an acceptable temperature.

Experts divide hot water supply systems into two types:

• Central system. Here the water is heated at a heating station. After this, it is distributed to apartments in multi-apartment buildings.
• Autonomous system. It is usually used in private homes. The principle of operation is the same as in the central system, but here the water is heated in a boiler or boiler and is used only for the needs of one specific room.

Both systems have the same goal - to provide home owners with hot water. In apartment buildings, a central system is usually used, but many users install a boiler in case the hot water is turned off, as has happened more than once in practice. An autonomous system is installed where there is no way to connect to central water supply. Only those consumers who use the central heating system pay for hot water supply. Users of an autonomous circuit pay for utility resources that are spent to heat the coolant - gas or electricity.

Important! Another column in the receipt related to DHW is DHW at one unit. Decoding ODN - general house needs. This means that the DHW column on one unit is the expenditure of energy on heating water used for the general needs of all residents of an apartment building.

These include:

• technical work that is performed before the heating season;
• pressure testing of the heating system carried out after repair;
• repair work;
• heating of common areas.

Hot water law

The law on hot water supply was adopted in 2013. Government Resolution No. 406 states that users central system heating companies are required to pay according to a two-part tariff. This suggests that the tariff was divided into two elements:

• thermal energy;
• cold water.

This is how DHW appeared on the receipt, that is, the thermal energy spent on heating cold water. Housing and communal services specialists came to the conclusion that risers and heated towel rails, which are connected to the hot water supply circuit, consume thermal energy for heating non-residential premises. Until 2013, this energy was not taken into account in receipts, and consumers used it free of charge for decades, since outside heating season The heating of the air in the bathroom continued. Based on this, officials divided the tariff into two components, and now citizens have to pay for hot water.

Water heating equipment

The equipment that heats the liquid is a water heater. Its breakdown does not affect the hot water tariff, but users are required to pay the cost of repairing the equipment, since water heaters are part of the property of homeowners in apartment building. The corresponding amount will appear in the receipt for the maintenance and repair of the property.

Important! This payment should be carefully considered by the owners of those apartments who do not use hot water, since their housing has a autonomous system heating. Housing and communal services specialists do not always pay attention to this, simply distributing the amount for water heater repairs among all citizens.

As a result, these apartment owners have to pay for equipment they did not use. If you discover an increase in the tariff for repairs and maintenance of property, you need to find out what this is connected with and contact management company for recalculation if the payment is calculated incorrectly.

Thermal energy component

What is this - a coolant component? This is heating cold water. The thermal energy component does not have a meter installed, unlike hot water. For this reason, it is impossible to calculate this indicator using a counter. How, in this case, is the thermal energy for hot water calculated? When calculating the payment, the following points are taken into account:

• tariff set for hot water supply;
• expenses spent on maintaining the system;
• cost of heat loss in the circuit;
• costs spent on coolant transfer.

Important! The cost of hot water is calculated taking into account the volume of water consumed, which is measured in 1 cubic meter.

The amount of energy payment is usually calculated based on the readings of the common hot water meter and the amount of energy in the hot water. Energy is calculated for each separate apartment. To do this, water consumption data is taken, which is learned from the meter readings, and multiplied by the specific heat energy consumption. The received data is multiplied by the tariff. This figure is the required contribution, which is indicated on the receipt.

How to make your own calculation

Not all users trust the payment center, which is why the question arises of how to calculate the cost of hot water supply yourself. The resulting figure is compared with the amount on the receipt and on the basis of this a conclusion is made about the correctness of the charges.

To calculate the cost of hot water supply, you need to know the tariff for thermal energy. The amount is also affected by the presence or absence of a meter. If there is one, then readings are taken from the meter. In the absence of a meter, the standard for the consumption of thermal energy used to heat water is taken. This standard indicator is established by an energy saving organization.

If in multi-storey building an energy consumption meter is installed and the housing has a hot water meter, then the amount for hot water supply is calculated based on data from general house accounting and the subsequent proportional distribution of the coolant among apartments. If there is no meter, the rate of energy consumption per 1 cubic meter of water is taken and the readings individual meters.

Complaint due to incorrect calculation of receipt

If, after independently calculating the amount of contributions for hot water supply, a difference is identified, you must contact the management company for clarification. If the organization's employees refuse to provide explanations on this matter, a written complaint must be submitted. Company employees have no right to ignore it. The response must be received within 13 working days.

Important! If no response is received or it is not clear from it why such a situation arose, then the citizen has the right to file a claim with the prosecutor’s office or statement of claim to court. The authority will consider the case and make an appropriate objective decision. You can also contact organizations that control the activities of the management company. Here the subscriber's complaint will be considered and an appropriate decision will be made.

Electricity used to heat water is not free service. Payment for it is charged on the basis of the Housing Code Russian Federation. Each citizen can independently calculate the amount of this payment and compare the data obtained with the amount on the receipt. If any inaccuracy occurs, you should contact the management company. In this case, the difference will be compensated if the error is recognized.
