What is Gcal? Gcal is a gigacalorie, that is, a measurement unit in which thermal energy is calculated. You can calculate Gcal yourself, but first study some information about thermal energy. Let us consider in the article general information about calculations, as well as the formula for calculating Gcal.

What is Gcal?

A calorie is a certain amount of energy that is required to heat 1 gram of water to 1 degree. This condition complied with in the conditions atmospheric pressure. For thermal energy calculations, a larger value is used - Gcal. A gigacalorie corresponds to 1 billion calories. This value began to be used in 1995 in accordance with the document of the Ministry of Fuel and Energy.

In Russia, the average consumption per 1 sq.m. is 0.9342 Gcal per month. In each region, this value may change up or down depending on weather conditions.

What is a gigacalorie if it is converted into ordinary values?

1. 1 Gigacalorie equals 1162.2 kilowatt-hours.
2. In order to heat 1 thousand tons of water to a temperature of +1 degree, 1 gigacalorie will be required.

Gcal in apartment buildings

In apartment buildings, gigacalories are used in thermal calculations. If you know the exact amount of heat energy that remains in the house, you can calculate the bill for heating. For example, if the house does not have a common house or individual device heat, then for central heating you will have to pay based on the area of ​​the heated room. If a heat meter is installed, then wiring is implied horizontal type either serial or collector. In this option, two risers are made in the apartment for the supply and return pipes, and the system inside the apartment is determined by the residents. Such schemes are used in new houses. That is why residents can independently regulate the consumption of thermal energy, making a choice between comfort and savings.

The adjustment is made as follows:

1. Due to the throttling of heating batteries, the passage of the heating device is limited, therefore, the temperature in it decreases and the consumption of thermal energy decreases.
2. Installation of a general thermostat on the return pipe. In this option, the flow rate of the working fluid is determined by the temperature in the apartment, and if it increases, then the flow rate decreases, and if it decreases, then the flow rate increases.

Gcal in private homes

If we talk about Gcal in a private house, then residents are primarily interested in the cost of heat energy for each type of fuel. Therefore, let’s look at some prices for 1 Gcal for different kinds fuel:

• - 3300 rubles;
• Liquefied gas - 520 rubles;
• Coal - 550 rubles;
• Pellets - 1800 rubles;
• Diesel fuel - 3270 rubles;
• Electricity - 4300 rubles.

The price may vary depending on the region, and it is also worth considering that the cost of fuel increases periodically.

General information about Gcal calculations

To calculate Gcal, it is necessary to make special calculations, the order of which is established by special regulations. The calculation is made utility services, who can explain to you the procedure for calculating Gcal, as well as decipher any unclear points.

If you have an individual device installed, you will be able to avoid any problems and overpayments. All you need to do is take the readings from the meter every month and multiply the resulting number by the tariff. The amount received must be paid for the use of heating.

Heat meters

1. The temperature of the liquid at the inlet and outlet of a certain section of the pipeline.
2. The flow rate of liquid that moves through heating devices.

Consumption can be determined using heat meters. Heat meters can be of two types:

1. Vane counters. Such devices are used to measure thermal energy, as well as hot water consumption. The difference between such meters and devices for metering cold water is the material from which the impeller is made. In such devices it is most resistant to influence high temperatures. The operating principle is similar for the two devices:

• The rotation of the impeller is transmitted to the metering device;
• The impeller begins to rotate due to the movement of the working fluid;
• The transfer is carried out without direct interaction, but with the help of a permanent magnet.

Such devices have simple design, but their response threshold is low. And also they have reliable protection from distortion of readings. Using an antimagnetic screen, the impeller is prevented from braking by the external magnetic field.

1. Devices with a difference recorder. Such meters operate according to Bernoulli's law, which states that the speed of a liquid or gas flow is inversely proportional to its static movement. If the pressure is recorded by two sensors, the flow can be easily determined in real time. The counter involves electronics in the design. Almost all models provide information on the flow and temperature of the working fluid, and also determine the consumption of thermal energy. You can configure the work manually using a PC. You can connect the device to a PC via a port.

Many residents are wondering how to calculate the amount of Gcal for heating in an open heating system in which hot water can be selected. Pressure sensors are installed on the return and supply pipes at the same time. The difference in the flow rate of the working fluid will indicate the amount warm water, which was spent for household needs.

Formula for calculating Gcal for heating

If you do not have an individual device, then you need to use the following formula for calculating heat for heating: Q = V * (T1 - T2) / 1000, where:

1. Q is the total amount of heat energy.
2. V is the volume of hot water consumption. Measured in tons or cubic meters.
3. T1 is the hot water temperature, which is measured in degrees Celsius. In such a calculation, it is better to take into account the temperature that will be characteristic of a specific operating pressure. This indicator is called enthalpy. If there is no necessary sensor, then take the temperature that will be similar to the enthalpy. Typically, the average temperature is between 60-65 degrees Celsius.
4. T2 is the cold water temperature, measured in degrees Celsius. How do you know how to get to the pipeline from cold water not simple, therefore such values ​​are determined by constant values. They, in turn, depend on the climatic conditions outside the house. For example, in the cold season, this value can be 5 degrees, and in warm times, when there is no heating, it can reach 15 degrees.
5. 1000 is a factor that gives the answer in gigacalories. This value will be more accurate than regular calories.

In closed heating system gigacalories are calculated in a different form. In order to calculate Gcal in closed system heating, you must use the following formula: Q = ((V1 * (T1 - T)) - (V2 * (T2 - T))) / 1000, where:

1. Q is the previous volume of thermal energy;
2. V1 is the heat carrier flow rate parameter in the supply pipe. The heat source can be water vapor or ordinary water.
3. V2 - volume of water flow in the outlet pipe;
4. T1 - temperature in the coolant supply pipe;
5. T2 - temperature at the pipe outlet;
6. T - cold water temperature.

Calculation of thermal energy for heating using this formula depends on two parameters: the first shows the heat that enters the system, and the second shows the heat parameter when the coolant is removed through the return pipe.

Other methods for calculating Gcal for heating

1. Q = ((V1 * (T1 - T2)) + (V1 - V2) * (T2 - T)) / 1000.
2. Q = ((V2 * (T1 - T2)) + (V1 - V2) * (T1 - T)) / 1000.

All values ​​in these formulas are the same as in the previous formula. Based on the above calculations, we can conclude that you can calculate Gcal for heating yourself. But you should seek advice from special companies that are responsible for supplying heat to the house, since their work and calculation system may differ from these formulas and consist of a different set of measures.

If you decide to make a “Warm Floor” system in your private home, then the principle of heating calculation will be completely different. The calculation will be much more complicated, since it is necessary to take into account not only the features of the heating circuit, but also the values electrical network, from which the floor is heated. The companies that are responsible for monitoring the installation of heated floors will be different.

Many residents have difficulty converting kilocalories to kilowatts. This is due to many manuals of measuring units in the international system, which is called “C”. When converting kilocalories to kilowatts, the coefficient 850 should be used. That is, 1 kW equals 850 kcal. This calculation is much simpler than others, since it is not difficult to find out the required volume of gigacalories. 1 gigacalorie = 1 million calories.

During the calculation, it should be remembered that any modern devices have a small error. Mostly they are acceptable. But you need to calculate the error yourself. For example, this can be done using the following formula: R = (V1 - V2) / (V1+V2) * 100, where:

1. R is the error of a common house heating device.
2. V1 and V2 are the previously indicated water flow parameters in the system.
3. 100 is a coefficient that is responsible for converting the resulting value into a percentage.
   In accordance with operational standards, the maximum error that can be is 2%. Basically, this figure does not exceed 1%.

Results of calculations of Gcal for heating

If you have correctly calculated the consumption of Gcal of thermal energy, then you do not have to worry about overpayments for utilities. If we use the above formulas, we can conclude that when heating a residential building with an area of ​​up to 200 sq.m. you will need to spend about 3 Gcal in 1 month. Considering that heating season In many regions of the country it lasts approximately 6 months, then you can calculate the approximate consumption of thermal energy. To do this, multiply 3 Gcal by 6 months and get 18 Gcal.

Based on the information indicated above, we can conclude that all calculations on the consumption of thermal energy in a particular house can be done independently without the help of special organizations. But it is worth remembering that all data must be calculated accurately using special mathematical formulas. In addition, all procedures must be coordinated with special bodies that control such actions. If you are not sure that you will perform the calculation yourself, then you can use the services of professional specialists who are engaged in such work and have materials available that describe in detail the entire process and photos of heating system samples, as well as their connection diagrams.

All summer the red gossips in soft murovs sang and danced, and now, when the cold weather comes, we will have to pick up pencils. After all, “there is still no heating.” And it is necessary to present at least some arguments to the heating network, calculating the heat received from it, for which it was “Paid for”.

When you need to dot all the i's

But a completely reasonable question arises: “How to count something that is invisible and capable of disappearing instantly, literally out the window.” There is no need to despair of this struggle with the air; it turns out that there are quite clear mathematical calculations of the calories received for heating.

Moreover, all these calculations are hidden in official documents of state utility organizations. As usual in these institutions, there are several such documents, but the main one is the so-called “Rules for accounting of thermal energy and coolant”. It is he who will help solve the question - how to calculate Gcal for heating.

The actual problem can be solved quite simply and no calculations will be needed if you have a meter not just for water, but for hot water. The readings of such a meter are already “filled” with data on the heat received. When taking readings, you multiply it by the cost tariff and get the result.

Basic formula

The situation becomes more complicated if you do not have such a counter. Then you will have to be guided by the following formula:

Q = V * (T1 – T2) / 1000

In the formula:

• Q is the amount of thermal energy;
• V – volume of hot water consumption in cubic meters or tons;
• T1 - hot water temperature in degrees Celsius. More precisely, use temperature in the formula, but reduced to the corresponding pressure, the so-called “enthalgy”. But in the absence of a better, appropriate sensor, we simply use the temperature, which is close to enthalgy. Professional heat metering units are capable of calculating enthalgy. Often this temperature is not available for measurement, so they are guided by the constant “from the Housing Office”, which can be different, but is usually 60-65 degrees;
• T2 is the cold water temperature in degrees Celsius. This temperature is taken from the cold water pipe of the heating system. Consumers, as a rule, do not have access to this pipeline, so it is customary to take constant recommended values ​​depending on the heating season: during the season - 5 degrees; off-season – 15;
• The “1000” coefficient allows you to get rid of 10-digit numbers and get data in gigacalories (not just calories).

As follows from the formula, it is more convenient to use a closed heating system, into which once poured required volume there will be no water supply in the future. But in this case you are prohibited from using hot water from the system.

The use of a closed system forces us to slightly improve the given formula, which already takes the form:

Q = ((V1 * (T1 – T)) – (V2 * (T2 – T))) / 1000

• V1 is the coolant flow rate in the supply pipeline, regardless of whether the coolant is water or steam;
• V2 - coolant flow in the return pipeline;
• T1 is the temperature of the coolant at the inlet, in the supply pipeline;
• T2 is the temperature of the coolant at the outlet, in the return pipeline;
• T - cold water temperature.

Thus, the formula consists of the difference of two factors - the first gives the value of the heat received in calories, the second - the value of the heat output.

Helpful advice! As you can see, there is not a lot of mathematics, but you still have to carry out calculations. Of course, you can immediately rush to your calculator on your mobile phone. But he advises you to create simple formulas in one of the most famous computer office programs - the so-called spreadsheet processor Microsoft Excel, included in the Microsoft Office package. In Excel, you can not only quickly calculate everything, but also “play” with the source data and simulate various situations. Moreover, Excel will help you build graphs of heat receipt and consumption, and this is an “unkillable” map for a future possible conversation with government agencies.

Alternative options

How do they exist? various ways providing housing with heat by choosing a coolant - water or steam, there are also alternative methods for calculating the heat received. Here are two more formulas:

• Q = ((V1 * (T1 - T2)) + (V1 - V2) * (T2 - T)) / 1000

• Q = ((V2 * (T1 - T2)) + (V1 - V2) * (T1 - T)) / 1000

Thus, you can do the calculations yourself, but it is important to coordinate your actions with the calculations of the heat supply organizations. Their calculation instructions may be completely different from yours.

Helpful advice! Often reference books provide information not in the national system of units of measurement, to which calories belong, but in the international system “C”. Therefore, we advise you to remember the coefficient for converting kilocalories to kilowatts. It is equal to 850. In other words, 1 kilowatt is equal to 850 kilocalories. From here it is not difficult to convert gigacalories, given that 1 gigacalorie is a million calories.

All meters, and not only the simplest brownie meters, unfortunately suffer from some measurement error. This is a normal situation, unless, of course, the error exceeds all conceivable limits. To calculate the error (relative, in percent), a special formula is also used:

R = (V1 - V2) / (V1+V2) * 100,

• V1 and V2 are the previously discussed coolant flow rates, and
• 100 – conversion factor to percentage.

The percentage of error when calculating heat is considered acceptable - no more than 2 percent, given that the error measuring instruments is no more than 1 percent. You can, of course, make do with the old proven method; here you don’t need to do any special calculations.

Presentation of received data

The price of all calculations is your confidence in the adequacy of your financial costs to the heat received from the state. Although, in the end, you still won’t understand what gcal is in heating. Hand on heart, let’s say that in many ways this is the magnitude of our sense of self and attitude towards life. Of course, you need to have some base “in numbers” in your head. And it is expressed in what is considered a good norm, when for an apartment of 200 square meters Your formulas give 3 gcal per month. Thus, if the heating season lasts 7 months – 21 gcal.

But all these quantities are quite difficult to imagine “in the shower”, when warmth is really needed. All these formulas and even the results they produce correctly will not warm you up. They won't explain to you why, even with 4 gcal per month, you are still warm. And the neighbor only has 2 gcal, but he doesn’t boast enough and constantly keeps the window open.

There can only be one answer here - his atmosphere is also warmed by the warmth of those around him, and you have no one to snuggle up to, although “the room is full of people.” He gets up in the morning at 6 and runs in any weather to exercise, and you lie under the blanket until the last minute. Warm yourself from the inside, hang a photo of your family on the wall - everyone in swimsuits on the beach in Foros in summer, watch more often the video of the last climb to Ai-Petri - everyone is undressed, it’s hot, then you won’t even feel the lack of a couple of hundred calories outside.

Having received the final printout of the heat meter readings, an inquisitive person naturally begins to analyze it. After all, the desire to save is natural under today's living conditions. The first question that concerns residents is how many Gcal are in 1 cubic meter of hot water. If we are talking about this, the question is legitimate - you got to pay. Everything is quite simple here. 1 Gcal is just that the amount of heat required to heat 1000 m3 (correctly 1000 tons) of water by 1 degree. Therefore, 1/1000=0.001 or 1 cubic meter of hot water is 0.001 Gcal. To this value when calculating for hot water General house losses are also added.

You can read what heat losses are, in short - general house losses are caused by the fact that while the water reaches your apartment, it will inevitably cool down a little along the way, but since heating network– the pipes through which the water flows belong to everyone, and everyone must pay for these losses together. It is especially strong in those houses where it circulates in order to keep it cool on bathroom heated towel rails. Heat losses here reach 35%, but in fact they are spent on heating bathrooms and it would be more correct to attribute them to heating. But this is unknown, he only counts what has passed through him.

Why heat bathrooms in the summer, we can only discuss with you; we will not change SNiPs, much less the existing pipe layout. Towel dryers cannot be thrown away, otherwise the circulation of water will stop in all apartments above and below you, and at the same time, in order for hot water to come out of the tap, it will have to drain for a long time, you will lose even more on the cost of water, while gaining practically nothing on heat - it will go away with warm water until you get to the hot one.
Now let's move on to the cost of 1 cubic meter of hot water for heating. With the amount of heat that hot water carries naturally, nothing changes here. But the method of comparison or calculation that many people use is not correct. What is the mistake when calculating the cost of 1 cubic meter of hot water Let's look at the amount spent on heating using an example.

Analysis of the printout and answer to the question - how many Gcal are in 1 cubic meter of hot water?

Let's try to analyze through the eyes of the consumer. As an ordinary consumer thinks: the data from the Qо column is divided by the data from the V1 column, i.e. Gcal per cubic meter, the result is a certain value, for example, for us 0.00209. These data are compared with neighbors - who has it cheaper?? Those who make such calculations are especially negative. Their data is off the charts. Although the result is less heat, does that mean they are being deceived? They started paying more per cubic meter of water! Why did you spend money, part of the savings was stolen!

And the answer to their question is very simple. Let's go back a little. exactly the amount of heat that is needed to heat 1000 m3 (correctly 1000 tons) of water by 1 degree. It was not for nothing that I marked “tons”, water at different temperatures (enthalpy) and pressure has different densities, when heated it expands and there is more of it, after it has gone around your apartments and cooled down, the volume of water decreased due to cooling, but in tons it will be the same. On the printout, if you look at columns M1 and M2, this is clearly visible. Some of the difference here is caused by the error of the instruments; in accordance with the heat metering rules, the error can reach 2% on one flow meter. Also, a small error is caused by the fact that the pressure at metering units in houses consuming less than 0.5 Gcal per hour of heat may not be measured, but programmed according to the actual pressure in the ITP, since pressure affects the overall metering only slightly, by approximately 0.1% of the overall accuracy of thermal energy measurement. And the main mistake is degrees or in these calculations the temperature difference between the supply and return pipelines, the dt column (circled in blue) which was completely forgotten about.

By definition, a calorie is the amount of heat required to heat one cubic centimeter of water by 1 degree Celsius. A gigacalorie, used to measure thermal energy in thermal power engineering and utilities, is a billion calories. There are 100 centimeters in 1 meter, therefore, in one cubic meter there are 100 x 100 x 100 = 1000000 centimeters. Thus, to heat a cube of water by 1 degree, it will take a million calories or 0.001 Gcal.

length, included in the system of English measures. It is used not only in the UK, but also in the USA and other English-speaking countries. In particular,

Distances when using weapons.

The yard has a certain relationship with other English measures of length. A yard is equal to 3 feet or 36 English inches.

History of the yard

The name of this unit of measurement comes from an ancient Anglo-Saxon word that denoted a straight branch or rod used to measure length.

The yard as a measure of length appeared in the 10th century. It was introduced by the English king Edgar (959-975), who determined its size very simply - based on the size of his own body. A yard was equal to the distance between the tip of the middle finger of the monarch's hand, extended to the side, and the tip of his nose. On the one hand, this was convenient, but as soon as a new king occupied the throne, the size of the yard had to be changed.

You, dear comrades, do not argue, because in any case you will see that I am right. The qualification of a meter as a commercial one cannot be determined by an agreement because an agreement is the will and consent of two parties, expressed in documentary form, but you must know the basics of law. And the qualification of the meter is given by the metrological service in accordance with the state system for ensuring the uniformity of measurements; the qualification of the meter is established in the state interests, in the interests of society for the rational use of energy. The interests of the state, which are initially superior to the two parties who entered into an agreement, cannot be trampled upon by the two parties even with their full consent. If the meter is not qualified as commercial, and the house management enters into an agreement with the supplier for the supply of thermal energy with payment according to the meter, then any resident of the house will be able, through the court, to declare this provision of the agreement invalid and obtain a recalculation of his payment according to the standards.

How to convert gigacalories to cubic meters

When receiving utility bills, it is quite difficult to understand many aspects of the calculations and understand: where did this or that figure come from? One of the striking examples of such “difficulties of translation” is payment for supplied heat. If your home has a single heat meter installed, then you will receive bills for the Gcal (gigacalories) used, but the tariff for hot water, as you know, is set for cubic meters. How to figure out how to calculate the cost of heat?

Instructions

Perhaps the greatest difficulty lies precisely in the technical impossibility of converting gigacalories into cubic meters or vice versa. These are completely different physical quantities: one serves to measure thermal energy, the other – volume, and, as suggests basic course physicists, they are incomparable. Consumer task utilities in the end it comes down to calculating the ratio of the amount of heat expended and...

The examples of calculations of the cost of hot water and thermal energy given by REC employees, although they are largely conditional, nevertheless show that the presence of a meter allows you to pay according to actual consumption. Calculation according to standards is almost always an overpayment.

It should be noted that hot water supply can be centralized or non-centralized.

Non-centralized water supply is the preparation of hot water in in-house autonomous systems engineering support. For example, when a boiler is installed in a private house or instantaneous water heater.

Only centralized hot water supply is subject to regulation (setting tariffs). In this regard, a distinction is made between open and closed hot water supply schemes.

Open circuit

With an open (centralized) heat supply scheme, hot water is selected for hot water supply needs directly from the heating network.

In accordance with current legislation, a two-component tariff is established for hot water in an open system, which consists of a component for the coolant and a component for thermal energy.

The thermal energy component is established by the regulatory body in the form of a one-rate or two-rate component, equal to the one-rate or two-rate tariff for heat energy, respectively.

The coolant component (and for utilities this is, as a rule, water that has undergone additional treatment at the boiler house) is installed as a single-rate component and is taken equal to the coolant tariff.

An example of calculating charges for hot water if there is an in-house meter

Data for calculation:

consumption volume 5 cubic meters.

The payment for hot water supply provided in the specified apartment will be: 5.0 * 89.38 = 446.90 rubles.

Calculation of the amount of payment for hot water supply in an open heating system provided in a residential area in the absence of an indoor metering device(in the presence of technical feasibility its establishment) is determined based on the consumption standard, the number of residents in the residential premises (registered) and the tariff for hot water.

An example of calculating charges for hot water in the absence of an in-house meter

Apartment house located in the city of Omsk, supplier of thermal energy to Omsk RTS JSC through the networks of the Omsk Municipal Heat Company.

Data for calculation:

consumption standard in the amount specified in Appendix No. 1 of the order of the Regional Energy Commission of the Omsk Region dated September 11, 2014 No. 118/46 for 5-story buildings, 3.4 cubic meters. m/sq. m (if it is not technically possible to install individual hot water metering).

two-component tariff for hot water, approved by order of the Regional Energy Commission of the Omsk Region dated December 19, 2016 No. 597/71, from January 1, 2017 in the following amount:

Conversion to one-component according to the following formula:

17.82 + 1422.60*0.0503 = 89.38 rubles/cubic meter. m;

where 0.0503 Gcal/cubic. m is the standard amount of thermal energy for preparing one cubic meter of hot water.

Number of residents – 3 people.

The payment for hot water supply provided in the apartment will be: 3.4 * 89.38 * 3 = 911.68 rubles.

Important ! If the apartment does not have a metering device and it is technically possible to install it, a multiplying factor is applied in the calculation, which is 1.5 from January 1, 2017.

The payment in the above apartment, taking into account the increasing factor, will be 3.4 * 1.5 * 89.38 * 3 = 1367.51 rubles.

Currently, in accordance with federal legislation, a gradual transition is taking place from open system hot water supply to closed.

Closed circuit

With a closed (centralized) hot water supply system, hot water from the heating network is used exclusively for heating, and hot water supply is provided through a separate circuit or carried out by heating tap drinking water in central heating points (CHS).

In accordance with current legislation, tariffs for hot water in a closed hot water supply system are set in the form of two-component tariffs, consisting of a component for cold water and a component for thermal energy.

The component for cold water is equal to the established tariff for cold water, the component for thermal energy is equal to the established tariff for thermal energy.

The amount of payment for utility services for hot water supply is determined in accordance with the Rules for the provision of utility services to owners and users of premises in apartment buildings and residential buildings, approved by government decree Russian Federation dated May 6, 2011 No. 354, according to formula No. 24.
