Hot water flowing from the tap without interruption is one of the signs of comfort in any room. However, Russian reality is such that people are not always able to use hot water all year round.

Installing an economical gas water heater will help solve everyday inconveniences.

Gas water heater is a device for heating water from a water supply system using gas combustion energy. At the same time, both natural and bottled (liquefied) gas can act as a “supplier” of this energy.

Depending on the principle of heating water, gas water heaters are of two types: storage and instantaneous.

1. Storage gas water heater (gas boiler).

This type of gas water heaters is a container (reservoir) from which hot water is distributed through pipes to water distribution points - taps.

The tank of a storage gas water heater, depending on the model, has a volume from 10 to 500 liters and is made either of steel coated with enamel or porcelain glass, or of of stainless steel with titanium coating.

One of the main advantages of Baxi storage gas water heaters is the ability to use a large number of hot water even during a complete shutdown of the water supply system. In this case, access to the water accumulated by the water heater is provided without any time delays.

Unfortunately, like everyone else technological device A storage water heater has a disadvantage due to the fact that the hot water remaining in the pipes between the tank and the tap cools down over time. For this reason, many users storage water heaters They are forced to open the tap and wait for the cooled water to “go down”.

This problem can be solved by installing a circulation system, which consists of a small pump connected by a small diameter pipe to a system of pipes through which water from the tank flows to the taps. The pump pumps the water remaining in the pipes, but not used by the consumer, back into the container, thereby preventing it from cooling.

2. Instantaneous gas water heater ( geyser).

In essence, instantaneous gas water heaters are high-speed heat exchangers in the form of copper spirals or stainless steel plates. The principle of their operation is as follows: a cold water flow from the water supply system enters the body of the geyser, inside which, due to heating, the water temperature rises. The water temperature is set by the consumer using a manual regulator, the water heating period is from 3 seconds to 2 minutes. Depending on the model, a flow-through gas water heater supplies the consumer with 10 to 27 liters of hot water per minute.

The main advantage of a instantaneous gas water heater is its ability to supply hot water in a volume not limited by the tank. Also, unlike storage gas water heaters, instantaneous water heaters are relatively small and, as a rule, do not require specially equipped premises.

However, when operating instantaneous water heaters, it is necessary to pay attention to pressure drops in the water supply system. An insufficient amount of water can lead to overheating of the heat exchanger and, accordingly, activation of the protection and blocking of the burner. Thus, until the pressure in the water supply is normalized, it will be very difficult to heat the water.

Instantaneous water heaters consume fuel only during use, that is, direct heating of hot water, which makes them more economical than storage water heaters.

Gas combustion chambers in a water heater

Gas water heaters, regardless of the principle of heating water, are equipped with combustion chambers, which, depending on the nature of the removal of waste fuel, are of two types - closed and open. In combustion chambers open type the process of fuel combustion occurs under the influence of natural draft, which entails the need to ensure a continuous influx fresh air to the room where the gas water heater is located.

The main disadvantage of a water heater with an open combustion chamber is that after its installation in residential premises that are not equipped additional ventilation, possible lack of air, a feeling of stuffiness and congestion carbon monoxide. For this reason, it is necessary to allocate a separate room for such equipment.

In gas water heaters using a combustion chamber closed type, the air is supplied outdoors using the so-called coaxial chimney, which represents the simplest design"pipe in pipe"

During operation in such a chimney, gas combustion products are ejected through an internal, narrower tube, while the air for operating the chamber flows through the outer pipe. The movement of combustion products of fuel and air is carried out using a small electric fan.

Ignition of gas in a water heater

Gas water heaters use different kinds ignition of gas in the burner, which, in general, can be divided into 2 groups:

1. Ignition of gas with a pilot wick.

In water heaters with a pilot wick, a semi-automatic system (piezo ignition and electric ignition) is used to ignite gas. In this case, ignition is carried out at the touch of a button.

Water heaters with this type of ignition consume more fuel, part of which burns in the duty wick.

2. Ignition of gas without a wick.

In this case, ignition occurs automatically using hydrodynamic or electronic ignition. In this case, the signal to turn on and start heating water will only be the consumer opening the tap.

In general, ignition without a wick is the most convenient and beneficial for the consumer, as it provides gas savings of up to 15%.

Automation.

Gas water heaters various types equipped with control and protective automation of varying levels of complexity.

Protective devices, as a rule, are automatic valves, which instantly cut off the fuel supply to the main burner. Protection is enabled automatically in the following cases:

— stopping the flow of water through the heat exchanger or reducing the pressure in the water supply system;

— failure or malfunction in the gas ignition system;

- absence or weakening of draft in the chimney.

In addition to automatic protective equipment, experts recommend installing stabilizers on gas water heaters, which help control the power of water flow, maintain the temperature set by the consumer, and also, to a large extent, the noise level of the equipment.

Control automation systems that are installed on water heaters include thermostats and command controllers. Thermostats are designed to regulate the temperature of hot water and are usually an additional control panel on the body of the water heater. But in some models of gas water heaters, thermostats look like a remote control with a moisture-repellent coating.

Command controllers allow the consumer to set the temperature for specified periods of time and completely turn off the water heater when hot water is not required. These devices, as a rule, are installed only on storage water heaters.

Features of placement, installation and maintenance of gas water heaters

When purchasing a gas water heater, the consumer is faced with the need to prepare the point where the system will be installed. Depending on the type and size of the water heater, this can be a separate room or a specially equipped place (part of a wall, corner, etc.).

The room intended for installation of a water heater must have a ceiling height of at least 2.2 m, and a volume of at least 8 m3 for equipment with an open combustion chamber and at least 6.5 m3 for a system with a closed chamber.

Regardless of the type of combustion chamber, there should be a ventilation duct, extending outside the room, or at least an indirect opening for air flow (gap between the floor and the door, grille, etc.).

The room in which the water heater will be installed must be heated and protected from frost. Otherwise, the water in the water pipes and tank will freeze, which will lead to equipment damage.

The wall on which the water heater will be mounted must have a non-flammable coating so that heating does not lead to a fire.

In general, it should be noted that the most optimal place for placing small gas water heaters - this is a kitchen or a room next to water points. For large-volume storage water heaters, basements and semi-basements are best suited.

Manufacturers and suppliers of gas water heaters often require that installation of the equipment be carried out exclusively by their employees. service department. It should be noted that such a requirement is quite justified, since employees who are familiar with the company’s water heater models can perform high-quality and safe installation of the system.

Most of the work when installing a gas water heater consists of connecting gas to the equipment and cold water, as well as in the installation and commissioning of automation. Gas is supplied to the system using copper or steel pipes, equipped gas taps and mechanical filters against pollution. A shut-off valve must be installed on the pipe through which cold water flows, which is closed during an equipment failure. In addition, they install on the gas water heater system check valve, preventing the return of heated water to the water supply system.

The quantity and configuration of equipment that can be additionally installed on a gas water heater depends on its type, type of combustion system and characteristics of the fuel (natural or liquefied gas).

Gas water heaters, like any complex ones technical devices, require periodic inspections to ensure they are efficient work. Service maintenance can be carried out both by the seller’s specialists and by employees of the company providing such services.

The frequency of technical inspections depends on the complexity of the equipment, but cannot be less than once a year.

To summarize this article, it is worth saying that gas water heaters are ideal for providing hot water on an ongoing basis and compare favorably with others in their efficiency, convenience, durability and independence from electrical network. Gas water heaters are equally successfully used for both domestic and economic needs in the presence of natural or liquefied (cylinder) gas.

On Russian market presents a wide range of domestic and foreign manufacturers with a large selection of models.

It is necessary to purchase gas water heaters only in new condition, checking that the seller has all certificates and permits. Installation of equipment should also be entrusted exclusively to qualified specialists who have licenses and work permits.

With flow-through heaters, everything is clear - geysers work much more efficiently than their electric counterparts.

Flow-through, storage and combined boilers - selection and operating features

And from the point of view of paying bills, “gas” hot water supply looks more attractive than the “electric” option. Any homeowner will agree with this opinion.

However, in the case of storage heaters - boilers - such a unity of judgment is not observed. Therefore, in this article we will try to find out which is better: a gas or electric boiler.

Gas water heaters

Round One – Design Review

Any boiler consists of identical components:

• A storage tank into which cold water flows. Moreover, the supply of cold water and the removal of hot liquid is carried out using special fittings.
• A heating element that increases the temperature of the water in the tank.
• Thermostat - a control and regulatory element that turns on the heater at a minimum temperature and turns it off when it reaches the specified degrees.
• A control panel that allows you to calibrate the thermostat by raising or lowering the set temperature in the tank.

At the same time, a gas boiler differs from an electric storage water heater only in the design of the heating element. An electrical appliance uses a heating element as a heater - a tubular conductor with high resistance that heats up when connected to the network.

The heater of a gas appliance is more complex. It consists of a gas burner built into a cylindrical combustion chamber, which is also a flue - a pipe that discharges combustion products outside the housing. In this case, the gas duct is built into the storage tank - it penetrates through it, like a samovar pipe. That is, the burning gas heats the air in the flue, which, in turn, transfers the temperature to the water in the tank.

Scheme internal structure gas water heater

As you can see: the heating element of an electric boiler is simpler than a similar unit of a gas appliance. However, a gas burner works for years without burning out or rusting from water. And the surface area of ​​the flue is much larger than the similar parameter of the heating element.

As a result, a gas boiler operates more efficiently than its electric counterpart. While the heating element heats a couple of liters, a gas burner can boil 3-4 times the volume of liquid.

So this round is left to the gas boiler.

Round two – comparison of installation processes

Dimensions and weight of electrical and gas boiler, designed to serve the same volume of liquid in the tank, are approximately equal. Therefore, the process of attaching the boiler to the supporting surface will be absolutely identical in both the “gas” and “electric” cases.

The boiler is connected to the hot and cold water supply network using standard scheme, common for both gas and electric storage water heaters.

Installation of a gas water heater

But the connection of the “energy line” is implemented according to completely different schemes.

An electric boiler is simply “plugged” into an outlet without asking permission from the energy company. The gas boiler is connected to the gas pipeline, with the support of the appropriate service.

Moreover, both connection schemes are equally simple - even a novice electrician or gas fitter can master them. However, due to excessive bureaucracy, installing a gas boiler will be much more difficult than installing an electric water heater.

Therefore, the gas storage boiler loses this round outright.

Round three - safety

An electric boiler may cause an electric shock or explode due to failure. safety valve venting superheated steam. The gas tank may catch fire or explode due to gas leakage. So, with the same bad luck, both owners of electrical appliances and owners of gas analogues will have problems.

Therefore, in the third round we have a clear draw. Moreover, a gas leak from the burner is just as unlikely as a “breakdown” of electricity to the tank body.

Round four – model prices

Electric boiler Vaillant VEH 200/6

with a tank volume of up to 200 liters and a thermal power of 8.5 kW.

Electric boiler Vaillant VEH 200-6

Costs almost 80,000 rubles.

Gas storage boiler Vaillant VGH 220/5 XZU

Vaillant VGH 220-5 XZU

With a tank volume of 220 liters and a heating power of 8.5 kW.

Costs 90 thousand rubles.

That is, taking into account a 10 percent excess of volume gas heater Compared to the electric analogue, the difference in price is almost imperceptible.

However, for small volumes the difference in price is still noticeable. For example, a 150-liter boiler

Ariston ABS PRO ECO PW 150V

Ariston ABS PRO ECO PW 150V

costs no more than 20 thousand rubles.

Ariston SGA 150 R

Ariston SGA 150 R

will cost 35 thousand rubles.

The difference in cost is obvious. However, almost all “small” boilers - up to 150 liters in volume - work not only as water heaters, but also as heating boilers.

Boiler-boiler gas Baxi NUVOLA 3 Comfort 280 Fi

Boiler wall-mounted BAXI NUVOLA-3 Comfort 280i

not only heats a room of up to 280 square meters, but also stores a supply of water of up to 60 liters.

Taking into account this nuance, the price is 66 thousand rubles

no longer seems exorbitant, since for 40-50 thousand (the balance minus the cost of a 60-liter boiler) you can’t buy a decent boiler with a thermal power of up to 28 kW.

Consequently, after a stubborn struggle, having received unexpected reinforcement from manufacturers, the gas boiler snatches the lead from electric heaters.

Round five – cost of operation

It's time to consolidate your success. Gas water heaters are going on the offensive and knocking out electric water heaters! Judge for yourself: the already mentioned Ariston ABS PRO ECO PW 150V spends 4.5 hours to heat a 150-liter tank to 45 degrees Celsius, consuming 11.2 kW of electricity. That is, the cost of heating, taking into account 2015 tariffs, will be 55 rubles.

And the more expensive Ariston SGA 150 R spends just over an hour (71 minutes) to heat the same 150-liter tank to the same temperature, consuming no more than 720 grams of liquefied gas or 0.8 cubic meters main fuel. That is, the cost of heating will be only 25 rubles.

As a result, the Ariston SGA 150 R gas boiler simply knocks out the Ariston ABS PRO ECO PW 150V electric water heater, leveling out the difference in cost over 600 hours of operation.

Break: let's summarize

At the end of five rounds, the gas boiler leads the score. It is more efficient than an electric heater (water heating speed reaches 20 liters per minute), but is more difficult to install (official permission from the gas service is required). But in terms of safety, neither model has any advantage. In terms of price, with a slight stretch - the trick of the manufacturers who combined a heating boiler and a boiler - the gas appliance wins.

In terms of operating costs, electric water heaters are a clear loser - a gas boiler costs half as much and heats water four times faster. As a result, gas storage heaters defeat their electric counterparts by an “economical” knockout in the fifth round after leading the overall standings throughout the “match.”

Storage gas water heater - floor-mounted, wall-mounted

Gas non-volatile storage water heater does not require connection to electricity. The ability to operate at low water and gas pressure, the device has no restrictions on the minimum water pressure, has low hydraulic resistance, the pressure at the point of water intake is almost equal to the pressure at the inlet. The ability to connect a recirculation line allows you to reduce the time of supplying hot water to remote water collection points. The capacitive design of the water heater (large heat exchange surface) reduces the process of scale formation, allowing preventative work use the device for a long time. The presence of a flame is monitored by a thermocouple, which turns off the gas when the flame goes out. The device is adapted to work with low quality water.

Among gas heating equipment, the famous South Korean manufacturer has long and successfully offered its line of products. Let's look at Daewoo gas boilers, study what their features are, how they are connected, and what problems they have.

1. Two common models
2. Daewoo DGB-100MSC
3. Daewoo DGB-250MSС
4. Comparison of two models plus problems

Of course, like everything done under the Daewoo brand, boiler equipment this brand is also produced at top level. The following advanced technologies are used in the design of Daewoo units.

• enhanced, diverse emergency control system;
• power is regulated using infrared sensors;
• there is an electronic burner adjustment;
• applied various technologies to reduce operating noise;
• there is protection against wind blowing into the chimney;
• The gas supply is stabilized by a special valve.

All these advantages provide additional comfort to consumers and simplify the rules for operating Daewoo gas boilers. Among the units of the described Korean brand, the following families are common:

To finally make sure how high-quality, multifunctional and safe equipment Daewoo produces, we will analyze in detail two specific brands of boiler equipment.

Two common models

We selected for study two popular wall-mounted models with two heating circuits. That is, these devices are installed on the wall, they have two circuits - for heating and for hot water supply.

1. Daewoo DGB-100MSC with a power of about 11 kW, the prefix “DGB” denotes the full name of the corporation “Daewoo Gasboiler”.
2. Daewoo DGB-250MSC with a power of more than 25 kW.

Let's look at the intricacies of operating these two copies of the brand, and at the same time examine typical faults similar Daewoo gas double-circuit boilers. First of all, it should be noted that the models that we have selected are the most frequently sold among all modifications of the described Korean brand.

Daewoo DGB-100MSC

This Daewoo gas double-circuit boiler is mounted on the wall, it provides heating of hot water supply, its power is 11.6 kW, and the area of ​​​​the room that it can absorb with heat is 130 square meters. m.

Let's see what main qualities are inherent in him.

• high-speed heat exchanger for hot water supply of plate type;
• when the gas pressure decreases, the unit operates stably;
• built-in power supply protects equipment from voltage surges;
• there is a remote control remote control, liquid crystal display.

These advantages indicate that Daewoo equipment is truly multifunctional and comfortable to operate.

The detailed instructions for the described Daewoo gas boiler contain all the necessary operating information.

The main provisions of the instructions are as follows.

1. Installation is carried out in accordance with the recommendations and sketches.
2. Before starting operation, the heating system is filled with water.
3. During the first start, the air is gradually removed. If the coolant pressure drops with an increase in the temperature of the heating circuit, add water.
4. The display panel uses a symbol system.
5. The boiler is activated by the control panel.

There are also several innovations applied in this model.

1. U circulation pump dry rotor and magnetic coupling, which ensures its durability.
2. The gas burner is adjusted using a patented mechanism.

It is clear that all these advantages cannot but affect the price; the cost of such equipment is also not small, but we will talk about this later.

Daewoo DGB-250MSС

This is also a wall-mounted dual-circuit device with a closed chamber for gas combustion, the power here is higher - 29.1 kW.

Accordingly, the room can be heated larger area, namely up to 290 sq. m.

The advantages of this device, in principle, repeat those inherent in the previous model.

1. There is also a built-in power supply.
2. The unit is also configured to low blood pressure gas
3. The only thing that makes this brand of heat generator stand out is that it is extremely compact and very powerful.

The instructions for use for this Daewoo gas boiler essentially repeat the instructions for the previous model.

Here are the main features.

1. After filling the system with coolant, a test run is done.
2. The boiler is controlled remote control using buttons, indication is carried out by conventional icons.
3. Codes possible errors specified in the detailed manual.

These codes indicate typical faults gas boiler Daewoos in which gas combustion is most often blocked:

• problems with the smoke removal system;
• lack of water;
• pump failure.

Comparison of two models plus problems

Now let’s summarize the information received on two Daewoo units into the table below. Here she is.

From this table it is easy to understand that the cost of the described equipment is not so high when compared with the price of equipment from other famous brands, in particular, those of German or Italian origin.

Now let's talk about typical malfunctions Daewoo gas boilers.

Gas storage water heaters

What is more common and how to deal with it.
Most cases of contacting repairmen, as years of operation of this equipment have shown, are associated with an incorrect first start. Therefore, during installation you need to pay attention to this stage Special attention. It is necessary to follow every letter of the instructions supplied with the equipment.

Although there are few common breakdowns.

1. There are cases of failure of the circulation pump, but this is more often due to untimely cleaning of the heat exchangers.
2. Crashes electronic system controls are possible, but occur quite rarely, judging by the reviews.

To organize the supply of hot water to a home or small manufacturing enterprise It is necessary to install some kind of water heating device. You can find it on the market various options, differing mainly in the method of heating water (flowing, storage) and the resource with which the heating itself is carried out directly (electric, gas and boilers indirect heating). Of course instantaneous water heater very convenient, as it allows you to get an endless amount of hot water, unlike storage options. In this category of devices, the leader, of course, is a gas instantaneous water heater, called a geyser. A geyser is capable of quickly and efficiently heating water, while consuming a minimal amount of gas. There are quite a lot of manufacturing options and technical capabilities of geysers, but the main difference between them is still the type of combustion chamber.

Advantages of geysers with a closed combustion chamber

A unit with an open combustion chamber that takes combustion air from the room and can cause various troubles in the event of a malfunction of the ventilation or chimney ducts is, to put it mildly, imperfect. In geysers with a closed type of combustion chamber, air intake and exhaust gas removal from combustion products is carried out forcibly, using built-in fans. There are models of speakers equipped with a coaxial chimney pipe, which is capable of providing high-quality air supply and exhaust. This type of dispenser is much safer, because toxic carbon monoxide vapors are practically excluded from entering the room; you just need to take the pipe outside, without additional installation or installation of a special chimney.

The principle of operation of geysers with closed combustion

A turbocharged gas water heater can be ignited:

• From piezo ignition - a spark ignites the burner when you press the piezoelectric element button;
• Hydroturbine ignition - a mini turbine generator is built into the unit; water, rotating the turbine blades, generates electricity, with the help of which the burner is ignited. The most important advantage of this type is complete independence from additional sources nutrition.
• Electricity - power from the mains or batteries.

An important advantage of these devices is the ability to adjust the heating temperature and the ability to set the preferred one. Temperature regulation usually occurs by decreasing or increasing the burner flame. Options for columns that allow you to regulate the temperature can be with an automatic control unit (the user simply sets desired temperature, displayed on the screen using buttons) and mechanically (less advanced option).

To operate a gas water heater with a closed combustion chamber, you only need correct installation and setting, and you will be provided with the volume of hot water you require at any time of the day, and the reasonable price for these devices will pleasantly please every customer!

Gas storage water heaters necessary in every private home, especially since if there is no boiler room nearby, you can forget about hot water. And it is very necessary, at least for a pleasant rest in the bathroom and a comfortable shower, washing dishes and cleaning the house.

Wide range of applications of gas storage water heaters

This is why storage gas water heaters are so popular among many customers and are purchased primarily for country houses and cottages. But they are also often used in city apartments in order to save on hot water supply, in office and industrial facilities and in other places.

It is not always possible to find gas water heaters for hot water in online stores, for the reason that their sales volume is not as high as, for example, other types of water heaters. However, on the website of the MirCli online store you can find quite big choice heater models to suit your taste and budget.

The devices under consideration have many advantages, but their main advantages are ease of maintenance and operation, efficiency, which means a constant supply of hot water, and their low price.

These devices are stationary closed-type boilers with atmospheric injection gas burner for liquefied natural gas, as well as ceramic heat sink rods. Water heaters allow you to store a large amount of water, depending on the volume of the tank. It can be different, each model has its own, but usually its sizes vary from 10 to 200 liters.

Differences and functions

Gas storage boilers come in two types: vertical and horizontal, and they differ from each other only in the position of the tank, so you need to choose them according to your bathroom. If this does not matter, you should take a vertical one, since usually with the same characteristics its cost will be lower.

Many such devices can be connected to several points at once, since their water supply allows this.

Many storage water heaters have their own protective functions, which will ensure their safe use in the home. So, if the flame in the pilot burner of a gas boiler for heating water suddenly goes out, the gas supply will be automatically turned off. A multifunctional regulator allows you to regulate the pressure in the nozzle, as well as the gas flow in the burner. This regulator is also useful in that it dampens pressure fluctuations in the gas network to the burner.

As can be concluded from the information above, or rather its connection requires quite serious work. But if, as a result, the consumer’s desire has not disappeared or he simply does not have a reasonable alternative, then only one question remains: which water heater is better?

It makes sense to create some kind of rating, but it hardly makes sense to include specific models in it. There are too many of them, and each boiler has its own characteristics and is designed for different conditions operation (user requirements). Therefore, it is better to compare manufacturers, whose range of models, as a rule, have the same type Constructive decisions, available or unavailable from competitors.

So, in the domestic market, the segment of gas storage water heaters, paradoxically, is represented by samples foreign production:

• BAXI. The famous Italian brand is represented by the SAG3 model series, with a tank capacity from 50 to 300 liters. The tank is made of steel followed by enameling. The combustion chamber is open type. A burner with a piezo ignition function allows you to quickly switch from natural to liquefied gas, operating effectively at low pressure in the gas and water supply and with absolute energy independence. Allowed if necessary parallel connection several boilers with installed thermal power from 4 to 20 kW;
• VAILLANT. Products of famous German brand is characterized by high reliability and durability. The domestic market offers models with tank capacities from 130 to 220 liters. Thermal power, which is necessary to heat such a volume of water to a temperature of 70ºC, varies from 6.3 to 8.6 kW. In terms of design, we also have a steel enameled tank with an open combustion chamber. The injection burner used is also capable of operating on natural and liquefied gas;
• ARISTON. Another representative of the Apennine Peninsula, which has its own production capacity in Russia (electric boilers of this type are definitely produced here trademark). The range is represented by household water heaters with a volume of 50-195 l, which allow wall-mounted and floor mounting. Technical solutions and the characteristics are similar to models from previously mentioned manufacturers, but the price is much lower. For comparison, a model with a volume of 195 liters costs approximately 38,000 rubles, while its analogues and the Vaillant VGH 190/5 XZU cost 46,500 and as much as 80,000 rubles, respectively;
• HAJDU. The products of the Hungarian brand are also one of the oldest on the European market. In Russia it is represented by boilers wall mounting tank volume 80, 120 and 150 l. This approach allows you to free up significant space compared to floor-standing analogues. In addition, water heaters from this company are distinguished by high efficiency, precise temperature control, the ability to operate in a chimneyless system and a warranty of up to 5 years. The price, which for the presented models is in the range of 25-33 thousand rubles, cannot but please;
• AMERICAN. The top five is completed by the line floor boilers MOR-FLO, made in USA. Models with volumes from 150 to 284 liters are presented here, which allows them to be used in domestic and commercial environments. In addition, they are distinguished by a reliable enamel coating, excellent thermal insulation, an open combustion chamber with a powerful burner (there is a piezo ignition function). MOR-FLO water heaters cope perfectly with work at various pressures of water and gas, are non-volatile, and can be connected to operate in cascade. Like the HAJDU models, they are distinguished by great warranty period(6 years) at a fairly reasonable price: the 190-liter G62-75T75-4NOV has a price tag of 41,000 rubles.

conclusions

A gas storage boiler can be an excellent way to provide your home with round-the-clock hot water in the absence of a centralized supply or when it is turned off. summer period. It should be remembered that for the safe and efficient operation of this equipment, you will have to take care of the gas supply, arrangement and provision of sufficient ventilation in the room.

As for the boilers themselves, foreign-made models are presented on our market, which allows the user to rely on them high quality. Each brand has a fairly wide range of types, which allows you to choose a unit suitable in terms of volume and power for domestic and even commercial conditions. The same applies to prices, because there are affordable offers from HAJDU and ARISTON, and there are products from more famous brands - BAXI and VAILLANT, the price of which can be much higher.

The presence of hot water in the house is now not a luxury, but a necessary sign of comfort. For this purpose, devices of various modifications and volumes are used. Among the many options, it is worth considering a gas storage water heater. The water in it is heated by the combustion of gas and is supplied for domestic needs.

What are the benefits of gas storage water heaters?

Such equipment provides a storage capacity finished product. Such structures are easy to install indoors. Thanks to their significant supply, you don’t have to worry about running out of comfort quickly. The product is enough for several points operating simultaneously. In addition, it does not depend on power supply.

They are characterized by low gas consumption. Volume storage capacity depends on the needs of the family. It should be remembered that the faster the water is removed from the tank, the more often the device turns on for heating. Therefore, if you decide buy gas storage water heater, then the volume of the tank should be 25-30% greater than the estimated quantitative volume of hot water.

Such equipment can be installed even at the dacha, as there are models capable of running on liquefied gas.

Classification of gas boilers

By type of combustion chamber storage gas water heaters, available for sale in the SKO online store, are divided into two types:
