What is the gas consumption in the gas water heater?

Anything related to gas traditionally causes some concern. But gas instantaneous water heaters have been used for many decades in city apartments that are not connected to a centralized hot water supply system, so the technology can be considered well-tested and reliable, and with the current level of technological development, it is also absolutely safe if operating conditions are observed.

Where should the gas water heater be located?

Connecting a household gas flow-through water heater is possible when it is moved from one room to another, replaced, or initially installed. The device must be located in the kitchen with a chimney 12 cm in diameter or ventilation ducts.

How much gas do you need to heat a 100m2 house?

To heat a house of 100 m2, excluding hot water supply, you need to spend 10 kW/h of energy. To obtain 10 kW/h you need 2 liters of liquefied gas, this is the maximum (peak) consumption. In fact, when the boiler enters operating mode, having warmed up the room, fuel consumption becomes an order of magnitude less.

How to install a meter?

Contact the gas service and write an application for installation. Take with you documents that confirm your ownership of the apartment, and a paid receipt for gas for the last month.

The gas service will tell you where and what type of device you can buy. It’s not worth taking any and anywhere - it may not suit you. When you buy a meter, go to the gas service again. They will calculate how much the installation costs. At the same time, they will set a date for the master to come.

How to choose the optimal water heater model?

The primary selection criterion is the performance of the device and the purpose of its use. As a rule, for private homes where water can be used simultaneously in the kitchen, bathroom, and shower, models with a power of 23-24 kW, flowing up to 15 l/min, are considered optimal. If you only use a shower and a kitchen tap, then a power of 17-18 kW is sufficient, providing 10-11 l/min.

Of course, the power of the equipment can be adjusted (decreasing or increasing the height of the burner flame):

manual adjustment - changing the position of the handle will allow you to adjust the thermal power. With a large flow of water, the temperature will be lower, and the opposite situation with a low flow.
automatic adjustment - the flame height is independently adjusted based on the amount of liquid flow.

Ignition type

Ignition in modern models can be carried out in several ways:

piezo ignition.
automatically from a battery spark.
automatically from a hydraulic turbine spark.

The first of the presented methods, the most outdated, involves the conversion of mechanical movement into an electrical discharge. When turned on for the first time, the user needs to press a button, which will activate the built-in piezoelectric element. The spark formed during the process will ignite the igniter and the main burner. Apart from the number of manipulations performed, this method is not economical. When ignited, the igniter burns for some time, thereby consuming gas (an increase in raw material consumption by a quarter has been recorded).

The last two methods do not require human intervention. When the tap is unscrewed, the ignition starts automatically, as well as the fan and the supply of combustible material. The only difference between them is the source of spark formation. For example, the operating life of a battery is about a year, and in the case of a hydraulic turbine, it is necessary to monitor the pressure, it should be no lower than 0.45 atm.

Popular manufacturers

An important criterion when choosing is the company’s image, its experience, production capacity, and ongoing modernization. The reliability of the finished column depends on the professionalism of the workers, and largely on the company. Let's look at the main players in the market:

Neva is a model of quality that meets European standards. When designing their models, the designers paid special attention to the safety parameter, so the product can contain many programs that make the models much more stable and reliable.

Bosch, as a rule, equips its equipment only with modern developments, which not only increase functionality, but also guarantee a high level of security.
Oasis – manufactures equipment that fully corresponds to the quality and prices set. The mechanisms of this TM are not as expensive as the previous ones, but they have the necessary set of additions.

Each of these manufacturers presents on the market models with different characteristics and parameters, which may also differ in the way combustion products are removed:

atmospheric (open chamber) - all substances are removed through the chimney.
turbocharged (closed chamber).

Equipment disadvantages

One of the significant disadvantages of this type of heating apparatus is the fire safety and explosion hazard of the fuel used during operation. In case of breakdowns, repair work must be carried out immediately. Only in this case will it be possible to avoid undesirable consequences in the form of fuel leakage, which negatively affects the human respiratory tract.

Before purchasing and installing such a water heater, you must first evaluate the supply power in the gas supply lines. If it is insufficient, then installation is absolutely not possible. In such cases, only storage type equipment can be installed.

The performance of the speaker can be significantly affected by the level of humidity in the room where it is installed. It is worth remembering that some manufacturers do not recommend installation in wet areas, and do not provide appropriate guarantees if this condition is violated.

How else can you save money?

Gas stove

Place dishes (kettle, pots, pans) on a suitable size burner. If the burner is larger, you heat the air unnecessarily. If it is less, the bottom heats up unevenly. Cover the dishes with a lid - this reduces heat loss by about 20%.

Heat the contents of the cookware to the desired temperature as quickly as possible. But after boiling, it is better to reduce the gas - the fire should not lick the walls of the pan. Don't burn gas in vain - for example, don't let water boil away in a kettle.

It is best to use energy-efficient stainless steel cookware with a polished bottom and a copper or aluminum layer. True, it costs more than usual. And throw away dishes with a deformed bottom - they waste one and a half times more gas.

An electric kettle, a coffee maker instead of a cezve, a microwave, a multicooker - all these appliances save gas (although they increase electricity costs).

And please remember the safety rules. Do not use the stove for heating. Do not dry clothes over it.

It sounds ridiculous, but some people still do this. But it’s so close to trouble. Starting a fire this way is as easy as shelling pears.

Geyser

A dishwasher saves at least 20 liters of hot water per day. To heat 20 liters, the dispenser spends 0.135 cubic meters of gas. This will be 4.05 cubic meters per month. On them you will save 4.05 × 5.835 = 23 rubles 63 kopecks. It's a small thing, but nice.

If you have an old gas water heater with a constantly burning wick, it is better to replace it. The wick spends from 5 to 20 cubic meters of gas per month, that is, it wastes up to more than a hundred rubles.

Don’t forget about special devices for saving water - we talked about them in the last article.

then you will have to pay for verification.

it will never pay off, all the counters are made in order to milk the people

It’s a no brainer that if it were unprofitable for the authorities, then the meters would be banned immediately =)) ¶

counters are a legal drain on the population.

it's like a loan. There are a lot of scams like “money now” with 2 percent per day.

meters remind you of the same thing - they lure you in with the idea that you will pay less. This is true. but that's all.

but then for installation, verification, repairs of this meter, or reprogramming there - all this will happen in the distant future, God forbid you will be forked out there.

For a hundred years in Soviet times we lived without meters and everything was fine. and now they say that people overpaid for water and gas! that is, install a meter and you will save and pay 3 times less. Wow. that is, all these years, for example, since the 1970s, they paid 3 times more? so let's recalculate then, return the excess overpaid, you yourself admitted it =))

Design and principle of operation of the product

A standard water heater is a metal box that is comparable in size to a kitchen cabinet. Inside it is the main system and mechanism that ensures the operation of the equipment. In addition, two pipes are connected to the box, which are responsible for the supply of water and gas.

The design itself consists of the following basic elements:

rear panel.
draft cap.
gas and water supply valves.
copper heat exchanger.
main burner.
pilot burner.
electronic circuit.
battery compartment.

When the water tap is opened, a valve in the mechanism is activated, through which gas is supplied to the pilot burner, which is responsible for igniting the main burner. This process directly depends on the type of equipment ignition. During the combustion of fuel, the amount of thermal energy that is necessary to heat water to a certain temperature is released. Thermal energy passes through a spiral-shaped heat exchanger, resulting in rapid heating.

After the water is heated to the desired temperature, the process of supplying it from the column to the open tap, through the outlet pipe, is carried out. The gas combustion products formed during operation are released into the atmosphere through ventilation or a chimney, which is a prerequisite for installing such a heating system.

It is also important to know that geysers presented by manufacturers on the market are of two types:

storage water heater;
a flow-type device operating from a gas supply.

Characteristics that you need to pay attention to when choosing the optimal model:

amount of hot water consumed. Using the device simultaneously by several residents may result in insufficient heated liquid accumulated in the heating tank.
use with a centralized pipeline is not recommended by experts, as there is a possibility of insufficient pressure.
installation feature. Storage tanks of the device, as a rule, are large in size (depending on the volume of liquid contained), so there is a need for a suitable location (floor or solid wall).

How do you pay for gas without a meter?

Gas stove

So, if the apartment has a gas stove (but no gas water heater or gas heating), then it is assumed that each tenant spends 10 cubic meters of gas per month. A family of three people - 30 cubic meters, of five people - 50 cubic meters.

This calculation method is beneficial to the management company, but not to consumers. After all, you cook for the whole family at once, and not everyone for themselves. And small children do not use gas at all.

One cubic meter of gas in the second half of 2022 in Novosibirsk costs 5.835 rubles.

It turns out that each resident of an apartment with a gas stove pays 58 rubles 35 kopecks per month.

There are three Ivanovs in the family; gas costs them 30 × 5.835 = 175 rubles 5 kopecks per month. There are five Petrovs, for them gas costs 50 × 5.835 = 291 rubles 75 kopecks per month.

The Petrovs have a gas water heater. It is assumed that they spend 16.2×5 = 81 cubic meters of gas on heating water.

Therefore, they receive a monthly bill for 81 × 5.835 (dispenser) + 50 × 5.835 (stove) = 472.63 + 291.75 = 764 rubles 38 kopecks per month (of which 472 rubles 63 kopecks are for the gas consumed by the dispenser).

The house where the Ivanovs live has hot water supply, so they do not pay for gas heating of water. Otherwise, we would have spent 16.2×3×5.835 = 283 rubles 58 kopecks on this, and the total gas bill would have been 26.2×3×5.835 = 78.6×5.835 = 458 rubles 63 kopecks.

Advantages of instantaneous water heater

Having decided to acquire this type of device, you first need to familiarize yourself with its main characteristics, model range, leading market manufacturers, as well as the advantages inherent to the device.

Advantages of gas models:

a gas flow-through heater is a budget option. This fact is explained by the fact that gas, which serves as the main fuel, is quite cheap in price compared to similar sources such as electricity, gasoline, etc.
The power of the city gas supply system is usually enough to install such a water heater at home.
availability of several connection options - to natural and liquefied gas.
affordable pricing policy of manufacturers.
multifunctionality. With their help, you can simultaneously provide hot water not only to the kitchen, but also to the bathroom with shower.
Compact dimensions allow installation in rooms with limited space. The system does not take up much space, leaving space for more efficient use.
Fast heating is a feature that other devices used for these purposes, for example, storage columns, cannot offer. The latter are the optimal solution for those who consume large quantities of hot water, but the heating process still requires time.

The average power of flowing gas equipment is 18-19 kW, which is quite enough for the normal life of the residents of the house. In addition to the technical parameters, it is also important to mention the appearance. The modern design of the products is significantly different from previous analogues, and goes well with the elements of any interior.

User reviews

Alexey Revenko, Moscow

I have been using a Neva Transit gas water heater for 3 years now. It is very convenient to manage, since it does not require unnecessary knowledge and skills from me; everything is controlled by a standard program. I would like to note that this type of heating is more profitable than centralized supply. In the latter case, it was very difficult to count on even warm or room temperature, but now I have the opportunity to choose the degree of heating myself, while saving significantly.

Nina Alekseeva, Ekaterinburg

After purchasing a new apartment, we immediately began replacing the plumbing and all related components. We thought for a very long time about what to do with the central water supply, and the craftsmen advised us to use a gas water heater, since the pressure in the pipes facilitates installation. I can say one thing: we were very pleased with the resulting effect and never regretted it.

Oleg Golod, Perm

This type of technology is a real find. This is what it means: technological progress does not stand still. Despite the fact that I only recently purchased the Neva 4011, I have already experienced all the advantages.
