TOP 10 best gas water heaters of 2020

Why do you need to know the gas consumption?

Household metering devices are used to know how much blue fuel was consumed over a certain period. But in order to install a meter, you must initially know how much blue fuel is consumed per month. It is not the average indicators that are taken into account, but the maximum parameters. For example, if the hot water in the house is turned off and you will have to use the kitchen stove often to heat it.

What is this data for? Very simple - each meter is designed for a certain amount of fuel consumed. If the power of the stove is small and there are no other devices and appliances operating on gas in the house, you can get by with the simplest and most inexpensive meter. If a water heater and individual heating are additionally used, the throughput of the meter should be much larger. You will also need to replace the gas pipeline pipes, choosing a complete set with a large diameter.

How to calculate the consumption of domestic gas by power, so that you can choose the "correct" metering device?

These data are given in the instructions for the cooker. If the documents are lost or there are problems with the translation of the data specified in the passport to kitchen appliances, you can use the average indicators: A 4-burner hob consumes 1-1.3 m³ / hour.

Calculation of gas consumption for heating a private house

As we said, heating with natural gas is very economical. In addition to the rather low fuel price, gas installations are distinguished by a high level of efficiency in the fuel combustion process.

In addition, it is possible to reduce the level of heat losses by insulating the walls, ceiling and floor in the house.

Another advantage of using gas is its environmental friendliness. When gas burns, a small amount of harmful substances is released into the atmosphere. When using gas, the walls of the equipment are not covered with corrosion, which increases the life of the boiler.

If there are no gas mains near your home, you can use bottled gas. The operation of such fuel makes it possible to control the consumption of natural gas for heating, more precisely to keep records of its consumption.

In addition, the use of cylinders is very convenient for heating seasonal homes. The cylinders are compact and mobile. To save on the purchase and delivery of bottled gas, you can equip a gas boiler room in the house.

Information in GOST

Information on the power of burners is strictly regulated by GOSTs and if the stove has the appropriate certificates and is allowed for installation in an apartment or residential building, it must comply with these parameters. So, in residential buildings it is allowed to install gas stoves with 2, 3 or 4 burners, the standard power of which should be:

• 0.6 kW - reduced;
• 1.7 kW - average;
• 2.6 kW - high.

  
  Information about the power of the burners is in GOST

Additionally, it is worth calculating the power of the oven, the average values ​​of which are within 2.5 kW. The final parameters will be about 10 kW.
Many people ask how it is possible to increase the power of a gas burner if it is insufficient or if it is necessary to transfer the stove from liquefied gas to the mains. Despite the fact that many experts give advice on how to do this correctly and what manipulations should be carried out with the valves, the burner itself, the gearbox, all these methods are illegal and unacceptable in relation to gas appliances. Such refurbishment can lead to accidents in the home and huge fines from the gas service.If the power of the stove is insufficient, the equipment must be replaced with a new one.

And what does the GOST say about this?

Let's make a reservation right away that we will not talk about the legal component of this issue, we will focus exclusively on technical aspects. The technical characteristics of gas stoves are clearly regulated by GOST. The document says that the number of burners on the tiles can be different (2, 3 or 4). Moreover, each of them is obliged to provide the required combustion, which is resistant to air currents.

The power of the burners, in turn, can be:

1. Normal (1,700 watts)
2. Increased (2 600 watts)
3. Reduced (600 watts).

On average, the power of one gas stove is about 10 kilowatts.

And no complicated mathematical calculations are needed in order to find out that the fuel consumption of one average burner is about 1.2 m3 / hour. Although this parameter is necessarily indicated in the manufacturer's instructions, whether it be natural gas or liquefied gas.

Note! If in your house there is a rather old tile, and the corresponding documents for it have long been "gone somewhere", then we recommend that you rely on the average indicators.

Consumption determination rules

It is almost impossible to determine how much gas will be spent in an hour, day, month, since there will be too many variables in the finished formula:

• the number of people living in the apartment (house);
• culinary addictions (dumplings are cooked for 15 minutes, cooking cutlets will take about 1 hour);
• using the burners at full or half power;
• season;
• use of dishes with different thermal conductivity.

  
  It is almost impossible to determine how much gas will be spent

Considering all this, it is possible to find out how much gas a gas stove consumes per month, hour or for another period of time only very approximately.

What services carry out the installation of gas meters

Acceptance of applications and installation is carried out directly by gas services or specialized companies. Together with the application, it is mandatory to present a technical passport for housing, in which it is planned to install a meter in the presence of a gas water heater and a permit from the supplying service.
Next, the gas pipeline and the apartment itself are assessed, after which it is possible to select the device and proceed with its installation.

When buying a device, the main criteria should be taken into account:

• quantitative fuel consumption;
• date of manufacture of the device;
• gas flow direction.

In order to correctly determine these parameters, it is necessary to calculate the total volume of gas consumed. To do this, add together the hourly gas consumption of the stove, gas water heater or boiler. After a certain period, which is set by the gas service (at the moment it is 3 years), periodic verification of the meters is provided.

Note: the replacement of the device is not determined from the moment of its installation, but is calculated depending on the date of manufacture of the meter.

How to determine the gas consumption of a gas stove per hour

How to correctly calculate the gas consumption in m³, knowing only the power of the burners? For this, the total power of the stove is divided by the thermal conductivity of the gas (average values ​​are 8-11 kW * h / m³).

If, for example, take a stove with an average power of 0.6 kW (1 pc.), 1.7 kW (2 pcs.) And 2.6 kW (1 pc.), Then the gas consumption per hour will be:

• 6.6 / 9.5 = 0.7 m³

If we take into account the gas oven, we get the following data:

• (6.6 + 2.5) / 9.5 = 0.95 m³

These calculations are conditional and imply the simultaneous operation of all 4 burners at full power for 1 hour (+ oven).The real parameters of gas consumption can always be found out by the meter, which records the amount of used blue fuel.

One counter or several?

It would seem that the answer is obvious. Two meters require additional financial costs for installation, design and purchase of the device itself. On the other hand, the presence of a second meter is justified if, in addition to the gas stove, other equipment that runs on blue fuel is used in the house. At the same time, the difference in average gas consumption indicators is very large and metering devices are not able to cover such a range. It will either not catch the minimum indicators (0.3 m³ / h), or it will not cope with high loads (more than 7-8 m³ / h). And then the second meter becomes a necessity.

The choice of suitable meters depends on the maximum (not minimum) power of the household appliance. Metering devices have special markings to help you choose a device with the most suitable operating parameters. A meter marked G1.6 or G2.5 is suitable for the stove, and the gas consumption of the boiler and gas column will be counted by a meter marked from G4 or more.

Important: if, in addition to the stove, a double-circuit boiler is used, and not two separate devices for heating and heating water, a second counter is not needed.

Features of mounting an accounting device

The rules for installing a gas meter are very simple - this work should only be performed by a specialist. Its tasks include:

1. Choosing a place to install the meter. It should be borne in mind that the meter should be located at a certain distance from the heating elements and be accessible for taking readings, performing installation and dismantling works;
2. Directly mounting the meter;
3. Sealing metering device.

   
   Installed gas meter

Experts have calculated who is more profitable to install gas meters

According to the law, metering devices were supposed to appear in apartments and private houses that are heated with gas before January 1, 2015. For residents of Crimea and Sevastopol, a delay was introduced until January 1, 2021.

It is not necessary to install a meter if the gas consumption is less than 2 cubic meters per hour. Apartments where there is only a stove from gas appliances are suitable for this definition. It is better for people who own water heaters to specify the fuel consumption in the characteristics of the device used. As the publication "Lifehacker" writes, residents of dilapidated or dilapidated housing, which was recognized as such before January 1, 2013, can do without a meter.

From 2020, and for Crimea and Sevastopol - from 2021, meters will be installed forcibly. The owner of the living space will be obliged to let the employees of the gas company to the place of installation of the device and pay the costs. If he refuses to do this, then the costs of the court and the compulsory collection of money will be added to the costs.

The publication "Lifehacker" considered the reasonableness of the placement of gas meters with different components and tariffs that are set in St. Petersburg. The consumption standards for gas utilities in residential buildings in St. Petersburg per person for an apartment with a gas stove is 10.4 cubic meters per month. For a family of two and in an apartment that has only a gas stove, gas costs per month will be 130.6 rubles (20.8 m³ × 6.27983).

If tariffs grow by an average of 5% every year, then the family will spend 8,661 rubles over a five-year period.

Suppose, in fact, such a family consumes only 5 cubic meters of gas per month. Then, under the same conditions, they will pay 2,082 rubles in 5 years. You can also add to the expenses the cost of the meter - on average 1 980 rubles - and its installation. For example, "Petersburg Gas Service" installs the customer's device for 1,970 rubles. The result is about 6,032 thousand rubles.

If a family spends 10 cubic meters of gas per month, then they will not be able to save.

As the publication calculated, the more people are registered, the more profitable it is to install a counter. The actual gas consumption with each new family member increases uncritically, however, according to the standards, it will increase significantly. For example, if four people were registered in the apartment, then more than 17,000 rubles a year would be spent on gas payments. Moreover, for a baby, the standard is the same as for an adult.

If the apartment has both a gas stove and a water heater, the standard in this case is 32 cubic meters per person, and the tariff is the same. This means that a family with two people will pay 402 rubles a month. For a five-year period, she will give 26 656 rubles.

The gas company will already take 2,970 rubles for installing the meter on the stove and column. In this case, the benefit will depend on the actual gas consumption and user savings. Generally, the older the column, the greater the flow rate.

In the event that gas heating is installed in the house, then you need to carefully approach the issue of whether or not to install a meter.

So, in St. Petersburg, the standard is 8.2 cubic meters per month per square meter of premises. As a result, 270.6 cubic meters of fuel and 1,700 rubles a month will be needed to heat a Khrushchev building of 33 square meters.

In order to heat a house of 100 square meters, 5,150 rubles will be required. Gas consumed for cooking, in this case, will need to be paid separately. According to Lifehacker, a meter in a large house is a profitable device, because according to the standard, you would have to pay the same in the winter months, when the boiler is running constantly, and in the spring, when you only need to periodically heat the house. In most months, less gas will be spent than indicated in the standard, because averaged parameters are used to determine it.

As a result of the calculations, the following conclusions can be drawn:

- the more people are registered in an apartment with a stove and / or a column, the more profitable it is to install a meter;

- if you only have a gas stove and 1-2 people are registered in the apartment, then you won't be able to save money;

- the less you use gas, the more profitable it is to install a meter;

- with gas heating, it is advantageous to install a meter in the overwhelming majority of cases. However, there is little choice under the law.

Gas saving tips

Despite the fact that payments for blue fuel used for cooking make up the smallest share of utilities, the savings are never superfluous. The desire to reduce costs, regardless of what gas is used in the gas stove, are quite justified, especially since they do not require any special efforts:

1. If the dishes are closed with a lid, the water in it will not only boil faster, but the average gas savings will be 20%. This method is effective for all types of dishes;
2. The bottom of the pot should be slightly larger than the burner flame. In this case, the heat is not wasted;
3. If the recipe does not involve gradual heating, the contents of the pot should be brought to the maximum temperature as quickly as possible. Otherwise, significant heat loss occurs through the walls of the dishes;
4. Drafts and air conditioners blow the flame to the side, increasing the heating time and gas consumption of the gas stove, on average by 10-15% per hour;
5. Do not use the stove for longer than necessary. This applies to a boiling kettle, a hot skillet, boiled eggs. When preparing some dishes, it is generally recommended to turn off the gas a little earlier than the food is ready. For example, when cooking cereals and pasta.
