The battery is due to high utility bills, the main part of which is for heating. High tariffs and at the same time cold batteries are caused by the lack of proper thermal insulation, installation defects and heating networks that have expired. Devices that record the consumption of relevant services allow you to pay only for what was actually received. Since the bills indicate the data of the common house meter, calculations are carried out on the basis square meters housing.
What you need to know
When deciding whether such a device is necessary, it is worth remembering that it is not a means of saving, but makes it possible to pay only for current consumption, and not for the total, divided among all residents. The heat meter for the battery in the apartment notes any fluctuations in temperature conditions and allows you to keep track of consumption only if proper operation thermostat and proper execution of the unit. If before leaving home, for example for work, you reduce the temperature by at least 1 °C, then by the end of the month you can notice an economic bonus of 6%.
Required documents
It is also worth remembering that installing such a device entails many difficulties, and, in addition to collecting a certain list of documents, problems may arise. self-training The documentation will take several weeks, you will have to visit the relevant institutions and collect the following:
- design data of the heat consumption device;
- technical conditions set by the authority providing the building with heat;
- permission from the balance holder of the building.
Additional coordination of all calculated data with the established values is required. The installation is carried out in accordance with all project information, after which an agreement is concluded with the energy supplier on the main documents for payment based on data from the apartment meter. Next, a representative of the relevant authority draws up a certificate of delivery of the installation and registers the device.
As it may seem at first glance, this does not cause any particular difficulties, but each of the points may imply an additional list of documentation, and receiving each of them may take up to two weeks.
Peculiarities
Prices for individual metering devices on average start at 4,000 rubles. Ultraviolet will cost more, more modern mechanisms, but their installation is not always rational in communal conditions.
A vertical heating circuit is characterized by the connection of several sections to one riser. IN in this case one riser pipe goes down, and the other comes out from above. Pipes in a horizontal pattern come out from the bottom and return back. This type of wiring has become most widespread in modern houses, although its arrangement is more expensive vertical version. Both types of breeding, one way or another, relate to water supply.
Battery heat meter: operating principle
Such an individual device is provided for premises with a horizontal pipeline diagram. Its operating principle is based on temperature measurements at the entrance and exit to the system and subsequent calculation of the energy spent by the coolant. Consumption data is recorded over several approaches, after which the resulting indicators are processed. New devices have a function for connecting to a PC and saving values for 10 years.
The heat meter for the battery has a flow meter in its design, 2 temperature sensor and a computer. The latter can have autonomous or external power supply. For the first option, you need to connect to a 24 V power supply and, accordingly, install an energy transformer; the second model is different short period service of power supply elements and sometimes insufficient length of wires.
Varieties
The device type is determined installed sensor flow rate, which has three variations.
The operation of ultrasonic flow meters is based on the use of a signal receiver and emitters with opposite positions. Externally, heat meters for a heating battery are presented in the form of a hollow section of pipeline equipped with an LCD display, sensors, a thermal calculator and thermometers. To count the data you just need to press a button. Such a device allows you to take readings while away from home, while it does not generate hydraulic pressure and is informative. Among the disadvantages, buyers note the need for a UPS connection in case of an unstable flow of electricity and the possibility of incorrect data in case of cloudy or airy coolant.
The heat to the battery is a hydrodynamic generator small sizes. It is distinguished by accurate indicators, provided correct installation. The main disadvantage is the formation of salts on the electrodes, which reduces the accuracy of measurements, which is also affected by electrical appliances.
The meaning of the operation of mechanical meters is as follows: a small turbine is introduced into the liquid, where it rotates depending on the flow rate. Such devices have the function of receiving remote signals to determine the current flow rate. Also, the heat meter for the battery is easy to use, budget-friendly and powered from its own source - batteries. It is possible to obtain greater savings by installing the regulator with a board and valves. The disadvantages include the inability to read data at a distance and store information received per day, and they also create pressure in the system and are subject to wear, like any other mechanisms.
Installing heat meters on a battery
Installation of the device depends on its functionality and does not cause any particular difficulties. On the system it is fixed to the supply and fits to the supply outlet. Next, two shut-off valves are installed, one on each side of the device. As the water moves, a filtration mesh is placed.
The connection of the device can only be carried out by a company that has special permission to provide such services. Experts conduct step-by-step installation, inspect the properties, register the unit and put it into operation. It is worth noting that many organizations involved in installation of devices carry out subsequent maintenance. They also undertake verification.
Saving
If the apartment has high-quality thermal insulation and constant temperature in the region of 25 degrees Celsius, using the regulator you can change the heating mode to a more comfortable one, while significantly fewer gigacalories will be spent. Shut-off valves are used to regulate and control the supply of thermal energy to radiators. A noticeable difference in bills occurs even with one turn of the tap.
The battery is installed mainly horizontally heating scheme, which has a separate floor section. The location of the living space is of particular importance. People living in corner apartments ah on the top and first floors, provided a comfortable temperature range is from 15 to 22 degrees Celsius, they will not notice any special budget savings.
Choice
Of particular importance are the degree of error, the amount of incoming data and their archiving. When choosing, the main criteria are the energy input circuit and the type of coolant. In this case, it is worth paying attention to the maximum data that is known to specialists of the relevant authority. The selection of a specific option is determined by the pipe connection of the device and the dimensions of the system pipeline. Heat meter for battery, reviews various models which differ greatly, usually has a smaller outlet size in relation to the pipes, which leads to an increase in hydraulic pressure at the installation site. This may affect the degree of error.
In the device model important parameters are the type of DHW device, thermal inputs and possible pressure changes. This indicator generally has a small value.

At one time, tariffs for public utilities were low and none of the consumers thought about installing water and heat meters. Now the prices have risen so much that a significant part of it is spent on paying for them. family budget. Especially a large amount The receipt includes the heating fee. Therefore, property owners, trying to save money, decide to install heat, gas and water meters. The fact is that payments for supplied services are charged by utilities in accordance with approved standards, and not based on consumption.
Why do you need a heat meter?
Of course, installing a heat consumption meter is beneficial, since the monthly amount for heating will be calculated according to current tariffs and based on the evidence taken from individual device accounting. Thus, the consumer who has installed a heat meter pays only for the services received without any attributions from the utility companies supplying the heat (read also: " "). In addition, owners have the opportunity to regulate the heating temperature of the rooms or utility rooms manually or automatically (subject to installation electronic system control).Consumers should know that a heat meter does not save energy; it allows you to pay for the energy actually consumed, and not according to approximate calculations obtained as a result of the theoretical development of state standards. Individual heat meters, such as in the photo, allow you to save a significant amount of money on paying for heating services, it can be up to 60%.
Types of modern heat meters
Commercially available heat meters for heating in an apartment are not one device, but a set of devices.The set may include:
- sensors;
- calculators for the amount of consumed thermal energy;
- flow, pressure and resistance transducers.
- brownie (industrial);
- apartment (individual).
Water is usually used as a coolant, heated to the desired temperature.
- heat calculator;
- consumption meter hot water.
Household (industrial) heat meters
Household or industrial heat meters for heating are used for installation at production facilities and in apartment buildings. To account for heat, one of three methods is used: electromagnetic, turbine or vortex. The main difference between industrial and residential appliances is their size. The diameter of house meters ranges from 25 to 300 millimeters. The range for measuring the amount of coolant is about 0.6-2.5 m³/h.Mechanical heat meters
Mechanical (or tachometer) heat energy meters shown in the photo are simple units. They usually include a heat meter and a rotary water meter. The principle of how this type of heating meter works is as follows: for convenience and accuracy of measurement, the translational movement of the coolant liquid turns into a rotational one.
A mechanical (tachometer) meter is a very economical purchase, but the cost of filters should be added to its price. As a result, the kit will cost the consumer about 15% less than other types of heat meters, but provided that the pipeline diameter does not exceed 32 millimeters.
U mechanical devices there is a significant drawback - they cannot be used when the coolant (water) has high degree hardness and, if it contains particles of rust, scale or scale, as they clog filters and flow meters.
Ultrasonic heat meters
Manufacturers offer consumers large selection models of ultrasonic heat meters. True, the principle of operation for all of them is almost the same: two devices are installed opposite each other on the pipe - an emitter and a device that receives ultrasonic signals. The emitter sends a special signal through the coolant flow and after a while the receiver receives it. The time interval between emission and reception of the signal depends on the speed of movement of water through the pipeline. When the time is known, the coolant flow is calculated.
In addition to its main functions, an ultrasonic heat meter can regulate the supply of thermal energy. These thermal energy metering devices are distinguished by greater accuracy of readings, they are more reliable and durable than tachometer devices.
Installation of heat energy meters
According to experts, the best solution The question of where it is better to install a meter is the installation of a common house heat meter. Then all consumers living in the house will not have to pay for thermal energy, which was not actually supplied to the building. But the cost is high. True, if you divide it by the number of apartments, it will be quite affordable.To install a common house heat meter, you will first need to carry out general meeting residents, document decision made(draw up and sign a protocol) and submit an application to the management company with a request to connect the unit. After the heat meter is installed, you will need a person from among the consumers responsible for timely taking readings from the device and issuing receipts for each apartment.
If not all residents of the house or entrance agree to install a heat meter, then the apartment owner should think about how to significantly reduce financial costs on individual heating own home.
Installation of an individual heat meter
Before installing a heating meter in a separate apartment multi-storey building You will need to perform a number of measures and actions, otherwise connecting the device will not be appropriate or legal.Step one . It is necessary to eliminate existing sources of heat loss, including cracks in windows that are not insufficiently insulated entrance doors, freezing corners. Only after this installation of a heat meter will result in significant savings cash.
Step two . The management company (housing office, homeowners' association) must provide the apartment owner with technical conditions (TU) - they contain the requirements that must be met in order to connect. Typically, the text of the conditions takes up an A4 sheet. It certainly contains information about the temperature and pressure of the coolant entering the pipeline of a particular house.
Step three . Knowing these parameters, you can start purchasing a heat meter from a company that operates legally. When purchasing a device, you must request a sales and cash receipt, certificate confirming quality, rules and operating instructions.
Step five . The measuring instrument is being installed thermal device by employees of a licensed organization specializing in this type of service.
When choosing a company, it is advisable to pay attention to a number of nuances:
- for the availability of information about the organization in the Unified State Register of Legal Entities;
- for package availability necessary documentation, including certificates, SRO approvals;
- availability of qualified specialists;
- for the availability of special equipment;
- for execution full list installation work;
- for availability free departure a specialist to the client’s apartment to inspect communications;
- for the presence of warranty obligations for the work performed.
To make life easier, the apartment owner has the right to order all of the above work in one place - from a company that provides this type of service for professional level, however, you will have to pay a considerable amount for this. If you have the desire and free time, you can prepare the installation documents yourself.
Checking heat meters
Typically, new devices are sold with an initial test, which is carried out at the factory that produces them. Proof that the verification of heat meters has been carried out is the presence of a special sticker corresponding to the entry, a special mark, both on the devices and in the documents attached to them.During operation, verification of heating meters is carried out at the expense of apartment owners once every 4 years; to carry it out, you must contact a number of organizations and institutions:
- to the Rostest department;
- to a company that has the appropriate authority to carry out the inspection;
- V service center manufacturing company.
They independently take readings from the heating meter in the same way as from the electric meter. The difference in readings is indicated on the payment receipt and multiplied by fixed tariff and make payments, for example, in one of the Sberbank branches. The recipient of the payment is the heat supply organization.

Restrictions on installing a heat meter in an apartment
Many consumers are interested in whether heating meters are installed individually in each apartment? The fact is that in most domestic apartment buildings When creating a heating system, vertical riser wiring is used, which prevents the installation of one apartment meter.In such a situation, there is only one solution - to install meters on heating radiators, but such a solution is difficult to implement for the following reasons:
- installing several heating appliances in one apartment will cost its owners a tidy sum, since each meter for a heating battery costs a lot of money;
- Taking readings from each device is made difficult by the fact that utility workers are not able to walk through all the rooms in the apartments of the house on a monthly basis to record the data. When doing this work yourself, you can get confused in the numbers and make mistakes in the calculations;
- presence of maintenance problems - several devices are much more difficult to control and verify their correct functioning;
- The meter for a heating radiator has poor accuracy, since the difference at its input and output is so small that the device is often unable to record it.
In buildings erected after 2000, horizontal wiring is used heating system, therefore, in such apartments it is enough to install one heat energy consumption meter, and distributors are not required.
As a result of the above measures, it is possible to significantly reduce monthly payments for services provided by utility companies through the installation of heat meters.
Today, everyone prefers to install heat meters for heating more apartment owners. The benefits of using these devices are obvious. After all, payment is made only for the heat actually received. This means you can save a lot of money. Manufacturers offer different models and types of battery meters. This article will discuss the following aspects: the principle of operation of the device, existing varieties, the cost of purchase and installation, as well as the question that worries many users about whether it is possible to deceive heating meters.
The cost of heating increases every year. Some people try to solve this problem by taking a more economical approach to heat: installing new windows and insulating their home. Modern double glazed windows They are energy efficient and allow you to save about 30% of heat.
Very often the owner of the house has to pay a lot of money during the heating season. At the same time, batteries do not always heat the room at the proper level. As a result, a person pays for what he does not receive. In this case, heating meters - great option saving money. By installing a meter in your apartment, you can save about 40% of the total payment for heating services. Installation pays off measuring instrument during 3 to 6 months of the heating season.
Sometimes poor heating is associated with the negligence of service workers and the reluctance of the operator to lose money on achieving the required coolant parameters. If the apartment has a heating meter, this can become a significant argument in the event of litigation with utility services.
The principle of operation of the battery meter
Let's take a closer look at how the heating meter works and what factors can affect its functioning.
A heat meter is installed to determine the volume of coolant in the radiator, as well as measure the water temperature level.
If the house has horizontal wiring, the unit is mounted on horizontal pipe. At the same time, one device per apartment is quite enough. But with vertical piping, you will have to install a separate meter for each battery.
It should be noted that the heating meter in the apartment is quite accurate. But there are a number of factors that can have a strong impact on the device and cause some error. For example:
What types of heating meters are there?
Depending on the installation method, the heating meter can be communal or individual. With the common building option, one metering device is purchased for the entire high-rise building. Despite the fact that the meter is expensive, it will be quite affordable for the owner of each apartment. After all, the total price will be divided among all residents. Despite the availability of a heat metering unit, savings may be low due to the fact that some apartments may be poorly insulated. As a result, everyone will have to overpay.
Therefore, many people prefer to install an individual meter in order to pay only for the heat actually received by the apartment. True, such a device is not suitable for every room. For example, installing a meter in an old house with a vertical type of wiring can be quite problematic. After all, the device is installed on a riser. And in such houses there are several of them. Installing a meter on each riser is very expensive. In this case, distributors are used.
Also, all heating meters for an apartment can be classified according to their operating principle into:
Features of installing a heating meter
It should be noted that self installation Heating meters in the apartment are unacceptable. This may result in refusal of registration, and the personal account will not be re-registered. It is also important to remember that the unit should be checked every four years.
To install the device, you need to perform a number of steps:
How much will it cost to install a heating meter?
For those who want to spend money wisely, a heat meter is best option investment. Of course, the price of the device is considerable. But if you consider that the purchase pays for itself fairly quickly, the meter is not that expensive. The price for a communal heating meter is more affordable than for a unit installed individually for one apartment.
The cost of devices depends on the type and manufacturer. We must remember that in addition to purchasing the device itself, you will also have to spend money on its installation. After all, installation should only be performed by a professional. It must be said that the price of heating meters includes, in addition to the equipment itself, some components: shut-off valves, control valve, filter. The average cost is from 9,000 rubles. If you add installation costs to this, the amount can rise to 20,000 rubles.
It is very profitable to buy meters in bulk: at the same time, the price for a heating meter will be slightly lower. This is possible, for example, if other residents plan to install this unit at the entrance for their apartments.
Features of calculating the cost of heating payments
The heating standard is calculated based on the amount of thermal energy that was consumed apartment building for one heating period. In this case, the volume of heat consumed is divided by 12 months and by the total area residential apartments. Thus, heating services are paid evenly throughout the year. You can find out how you can regulate the temperature of the heating battery.
By installing a meter on the battery, the heating fee is summer period will not be charged.
The owner of the apartment will pay based on the heat received. If there is a device that measures heating, its data must be taken monthly and submitted to the appropriate services.
Is it possible to cheat the heating meter?
Despite the fact that heating payments using an individual meter are much lower than without of this device, many are trying to deceive measuring equipment for even greater savings.
Known today different ways stopping the heating meter. For example, you can tamper with the internal mechanism of the device. To correct the heat meter readings, a special powerful neodymium magnet is also used. This allows you to underestimate the readings of the device. Some also use a method such as installing thermal converters on the return and supply pipelines.
There are other options for cheating the heating meter, but it is better not to use such saving methods. Modern models metering units have a volatile memory in which all readings are recorded. And using a computer, it is very easy to calculate these indicators. Drastic changes will be immediately visible. Therefore, it is better not to try to deceive the meter, but to think about how you can insulate the apartment and save heat.
Heat distributors are still not very common in our country, although in Europe they are used in industrial scale, since the 70s, and the number installed devices heat distributors number in the tens of millions. We do not yet produce these devices, although we already have experience in using them.
Operating principle of distributors.
The photo shows a thermostatic regulator and a radiator installed in the apartment. The distributor measures the temperature of the radiator surface at one specific point every 3-4 minutes and records the temperature difference between the radiator surface and the air in the room into a non-volatile memory. The resulting heat corresponds to the amount of heat given off by the radiator over the past period, measured in conventional units. Precisely conditional, the readings of the heat distributor are multiplied by radiator coefficient, corresponding this type and the size of the heating device.
At the same temperature on the surface of large and small radiator and at the same temperature in the room, the readings of the distributors will be the same, but a large heating device will give off more heat? To take this situation into account, the radiator coefficient is used. Each manufacturer has tables of radiator coefficients for its devices for all types of radiators produced. Radiator coefficient tables include computer programs to recalculate payments, and the coefficients are automatically taken into account when calculating.
But what about our homemade radiators or battery assemblies, when residents independently add sections to an existing radiator, while some of them practically do not heat. There is only one conclusion: you will have to get rid of homemade products.
Cost of heat distributor and calculation for heat.
The cost of a heat distributor is approximately 10 times less than the cost of a residential heat meter. The distributors can be easily installed on any type of heating device. This is the main advantage. Thanks to this, the cost of a set of devices for an apartment is acceptable even if there are several risers in the apartment.
Heat distributors are suitable for all heating systems.
Calculation of payment for heating based on the readings of heat distributors is the distribution of the total amount paid to the heat supplier between separate apartments proportional to the readings of the radiator distributors. At the same time, apartment residents make monthly payments throughout the year at fixed, pre-calculated and approved rates, and settlements with the heat energy supplier are made at
Once or twice a year, readings are taken in apartments, and the total amount is distributed according to the readings received. For each tenant, a balance is displayed between the amount of his payments at preliminary rates and his estimated payment. The amount received goes towards heating payments for the next year.
Thus, if there is any type of individual heat metering devices, heating payments depend on actual heat consumption in apartments.
Finally, let’s compare the costs of installing radiator thermostats and heat distributors.
Equipment and costs, Price per piece (at the rate of 1 $ - 60 rubles)
- Sensor-distributor for individual metering INDIV-3 with visual reading from the LCD display
- Sensor-distributor for individual metering INDIV-3R with remote wireless data transmission (radio)
- Installation of thermostat and sensor-meter
- Annual door-to-door payment services
The table shows the costs for installing radiator thermostats and heat distributors
The calibration interval for heat distributors is 10 years. Residential heat meters – 5 years.
Payback period for installing heat distributors and radiator thermostats for two-room apartment 1 year, with a service life of the thermostat 30 years, and a heat distributor 10 years. For budget-conscious residents, this period will be even shorter.
Remember the basic rules for organizing apartment metering using heat distributors:
- on heating devices V mandatory Thermostatic regulators must be installed.
- At least 75% of heated rooms in the building must be equipped with thermostats and heat distributors.
- the actual consumption of thermal energy for heating a residential building should be produced by a common house heat meter.
- The housing organization must organize recalculation of payments for residents based on readings from common house and apartment metering devices.

Receiving utility bills sometimes makes me feel hot. The reason for this is not the hot radiators in the apartment, but the unfair amount presented for payment. Perhaps you were lucky, and during the heating season the rooms had a pleasant temperature, or you, suffocating from the heat, shared the warmth with environment. But it may also be that the degrees of heat were clearly not enough and it was necessary to additionally insulate, but, nevertheless, the discomfort in no way affected the amount on the receipt.
Indeed, if the receipt reflects the figures based on the readings of the house heat meter, without taking into account individual heat consumption, the calculations are general character, and the amount is calculated based on the availability of square meters.
Benefits of a home meter
If you are ready to decide to install a personal heat meter in your apartment, remember that it will not give you economic effect, But will save money on heating within reason, reflecting current consumption. You will notice that the slightest vibration temperature regime in the direction of decrease will be reflected in the contents of the wallet towards the vector of increase.
The counter allows control consumption if the unit is installed correctly and the thermostat controls the temperature. By lowering the temperature before leaving for work, at the end of the month your rationality will turn out to be economic bonus. Only reducing the parameters in 1C to 6% saves thermal energy.
If you are thinking about installing the device in an apartment, you should know that the procedure is unreasonably complicated; you will need to assemble the required list of documents, and prepare for unexpected expenses.
Required documents
The installation process, meter registration and document collection varies within 6 -8,000 rub. If you want to prepare the documents yourself, be patient for a couple of months, visit the relevant authorities, and you will receive:
- Permission from the institution on whose balance sheet the house is located.
- Technical requirements from the balance holder of the building supplying heat.
- Calculated design of the heat consumption unit based on the selected device. Ready calculations are additionally coordinated with standard values.
- At this stage, installation should be done in accordance with each figure of the project.
- Conclude an agreement to the main contract with the heat supplier, providing for payment based on individual meter readings.
- Draw up a certificate of completion of installation of the unit with a representative of the organization supplying heat and register the device.
At first glance, the list does not imply any particular difficulties, if not for the obstacles in the form additional documents for each item, and waiting for permits for up to 15 days.
We are studying the heating system in the apartment. If there is a one- or two-pipe heating scheme, the installation issue automatically disappears in the same way as with autonomous heating.
A horizontal heating scheme with a separate ceiling unit is what you should start from.
The location of the apartment has great value. To the owners corner apartments on the first and top floors you don't have to worry. If for you comfort is indicated by an interval of degrees from 8 to 22C, you will not feel a noticeable difference in budget savings.
Price individual meters hesitates from 5000 -8000 rub. Modern ultraviolet devices are more expensive, but are not always relevant for municipal conditions. The vertical contour is due to the connection of each section to separate riser(two pipes): one comes out from above, the other is directed downwards.
With a horizontal heating scheme, the pipes come out of the floor and return there.
In modern buildings, such wiring is usually used, although it costs 20% more expensive previous type. Vertical and horizontal separation also applies to the water pipeline.
Technical characteristics of the heat meter
Apartment heat meter is intended for apartments with horizontal wiring
pipes The operating principle is based on measuring the temperature at the exit and entrance of the system and calculating the heat used through the coolant.
Accounting is due to several approaches to recording expenditure indicators with subsequent processing of the received data.
Modern models have access to computer and the counter values are stored in the device memory up to 10 years.
The heat meter consists of:
- computer;
- 3 sensors: 2 temperature and 1 flow meter.
Calculators come with external and self-powered:
- the first type is characterized by a short length of wires and short-lived batteries (from 6 years);
- the second model requires a 24 V power supply, which requires the installation of an energy transformer.
Flow sensors are available in 3 types, and determine the heat meter model.
Electromagnetic flow meters
The devices are presented in the form of a compact hydrodynamic generator. Characterized by accuracy of numbers, but they react to the proximity of electrical appliances and require proper installation. The main disadvantage is the formation of salts on the electrodes, which affect measurement accuracy.
Ultrasonic models
The work is based on the principle of oppositely installed signal emitters and receivers. Appearance indicated by a hollow section of pipe with attached sensors, two thermometers and a heat calculator, equipped with an LCD display. All you need to do is press a button to read the information.
- the device is informative;
- does not create hydraulic pressure;
- possibility of remote reading of indicators.
- ultrasonic models may display incorrect readings when the water is airy (bubbles) or in a turbid environment;
- If the power supply is unstable, it requires connection via UPS.
Vane (mechanical) meters
The essence of the work is reduced to the following: into liquid the turbine is inserted, rotating relative to the flow speed. The device is equipped with a remote signal device that reads the current flow rate.
- reasonable price;
- powered by internal source- batteries;
- ease of operation.
- sensitive to water hammer;
- the turbine, like any mechanism, wears out;
- creates pressure in the system;
- the model is not capable of storing daily information;
- impossibility of remote reading of indicators.
Installing a regulator complete with valves and a circuit board will contribute to even greater savings. If the apartment has high-quality thermal insulation and the temperature is kept within 26 °C, the regulator is able to adjust the thermal regime to comfortable values of 22 °C, while the meter will count significantly less hecto calories.
The presence of a device in an apartment implies control and regulated heat supply to radiators using shut-off valves. Even with one screwing of the tap (turning off everything is prohibited!) there is a noticeable difference in payment.
For example, for 35 sq. m. owner pays up 2000 rubles. By installing a meter, you will save at least a thousand. Savings depend on sq.m. m. room and if there is a large footage, the advantage will be obvious.
Choosing a residential meter
Installation of the device is permitted to companies licensed to carry out such work, otherwise the acceptance certificate will not be signed. Do the right purchase a specialist from heat supply organization, competently instructing about the characteristics of the design. Typically the requirements are:
- to sensors responsible for transmitting indicators at a distance;
- the volume of incoming information, as well as its archiving;
- error values.
The main criterion in the selection is the coolant and the heat input scheme, in which an important role is played maximum performance, known to specialists of the heat supply company.
There are certain points regarding the choice of heat meters, due to pipe size system and pipe connections in the device. Typically, the outlets of the meter are smaller than those of the pipes, which provokes an increase in hydraulic pressure along the installation section. This also affects errors in numbers, and in the direction of increasing consumption.
Important determining parameters in the device model are thermal inputs, presence and type of system DHW.
We also mean pressure drops in the system. Quite often the indicator is characterized by a small value.
Installation options
The installation scheme of the structure does not involve any difficulties and depends solely on its functionality.
- The sensors are installed in the system on the supply or return side, and are attached to the supply outlet.
- One shut-off valve is installed on each side of the meter.
- It is required to place the filter mesh in the direction of water flow.
After graduation heating season, the owner is obliged to take readings and submit them for approval of the tariff. The values are taken as from an electric meter: the difference in numbers is multiplied by the tariff.
Inspection is considered a mandatory procedure once every 4 years. In case of malfunction, the metrologist has permission to dismantle and seal after troubleshooting.
The result of all your efforts will be material savings and heating resources. In about a couple of seasons, the investment will pay off, and the low amounts on receipts will no longer be shocking.
