Best Gas Storage Water Heater 2022: A Hot Alternative to Cold Water Cutoffs. Which gas storage water heater to choose

A geyser is a flow-through water heater that runs on natural gas. If you do not have hot water supply, but gas is supplied, this equipment will increase the comfort of your life. You simply open the tap, hot water flows out of it, and its temperature is regulated by you yourself. Even if you have a centralized supply of hot water in your house or apartment, but you are not satisfied with the price you have to pay for heating, or perhaps you are not satisfied with the temperature, installing a gas water heater will also solve these problems. Heating water costs much less than it is provided centrally - this results in significant savings on utility bills. To understand which geyser is better, you will have to study the structure of the equipment and its types. Then the choice for you will be simple and conscious.

Which geyser is better depends on your requirements

The principle of operation of a storage gas boiler

There are several different types of water heaters. Despite the difference in design, all tank-type gas boilers have the same operating principle. Water heating is carried out as follows:

Combustion chamber - at the bottom of the housing there is a burner with forced or natural draft. When gas is burned, heat is released. Unlike flow columns, the burner is not in direct contact with the heat exchanger. The task of the combustion chamber is to generate heat and direct it to the flame tube.
Heat exchanger - the boiler does not have radiators usual for instantaneous water heaters. The heat generated by gas combustion is directed into the flame tube. The walls of the heated pipe are in contact with water for hot water supply. Heat exchange occurs.
Supplying water to the consumer - the heated liquid remains in a heat-insulated container. The water heater automatically maintains the temperature. When you open a water supply tap, hot water pressure is created, as in a conventional boiler, by displacing it with liquid from the cold water supply. Hot water is instantly supplied to the consumer.

The first heating is carried out within 20-30 minutes. After which the boiler continues to maintain the required comfortable temperature, while gas consumption is reduced to a minimum. The internal device contains: automation, a system to prevent calcium deposits (magnesium anode), as well as various sensors (gas pressure, water pressure, draft). The volume of storage tanks for household purposes varies from 80 to 200 liters.

How to choose a storage type gas boiler

There are several dozen different models of boilers on the gas water heating equipment market. When choosing, experts recommend paying attention to several technical characteristics:

Tank type - how to correctly calculate the volume of a storage tank is explained below. In addition to calculations, you need to decide on the choice of tank material. Manufacturers make tanks from the following types of metal:
With an enameled tank - there are several types of coating. Previously, the boiler tank was protected using ordinary enamel, which was used to cover dishes. Cheap water heater models still use this type of protection. Disadvantages: susceptibility to mechanical damage and thermal effects. The service life, even with careful use, does not exceed 5 years. Glass-ceramic coating is a modified enamel with good strength characteristics and heat resistance. Glass ceramics have a longer service life, up to 7-8 years of service.
With titanium coating - the characteristics of boilers are similar to those made of stainless steel. The tank of a capacitive boiler will work freely for at least 10 years, and the durability is not affected by the intensity of water heating (as is the case with a conventional enamel coating).
Burner type - there are conventional atmospheric and closed burner devices, with forced oxygen supply into the chamber. When choosing, they are guided by the technical conditions of the room used for installation. There are several types of storage tanks:
Turbocharged storage water heaters with a closed combustion chamber - oxygen is supplied from the street (models with a coaxial chimney) or from the room, in a forced manner. Turbo boilers are economical. Disadvantages: noisy when turned on, volatile.
Ignition type - not all water heaters work the same. Based on the inclusion principle, there are two main types of drives:
Piezo ignition - in this case, a constantly working wick is provided inside the water heater. Ignition is done manually. The igniter flame is ignited by a piezoelectric element. The wick works continuously and lights the main burner.
Fuel type - tank-type boilers operate on propane (bottled gas) and methane (from the central line). There are universal models. The latter can be easily converted to alternative fuel after changing the injectors and switching the mode. Water heaters with the ability to operate from a cylinder can be connected to a gas tank.
Installation principle - the drives are designed in two solutions. The first ones are intended for floor installation. The volume of storage capacity is practically unlimited. Water heaters for wall mounting are limited in volume. The maximum capacity usually does not exceed 100 liters.

After selecting a storage tank according to the 5 criteria described above, we proceed to calculating the volume of the storage water heater. You can do the calculations yourself.

How to calculate the volume of the boiler?

To choose the right boiler with the right volume, you must remember that there should be 50 liters per person. If installation is required for a family of four people, then a boiler with a capacity of 200 liters can be considered the optimal choice. But we note that calculating the capacity of a gas installation is an individual matter. If the family does not waste water, then in this case a tank of 50 or 120 liters will be sufficient . However, such a boiler installed in the bathroom will not allow all family members to take a bath consistently. You will have to wait some time for the water to heat up.

Advantages of indirect heating boilers

Gas and electric boilers for heating are a good alternative to double-circuit heating boilers. According to a number of parameters, boilers with indirect heating, complete with a single-circuit heating generator, are more convenient. When hot coolant is removed simultaneously from several taps (for example, in a bathroom), the pressure in the system decreases, as a result of which temperature surges and changes in the operating mode of the boiler cannot be avoided. At the same time, an electric boiler for heating a house provides several points for dispensing water, the temperature of which remains unchanged.

At its core, a gas and electric heating boiler is nothing more than a large thermos. In summer, it allows you to provide hot water throughout the day without frequently turning on the boiler. Additional ease of use is provided by connecting a recirculation system.

Gas boiler installation

The owner exposes himself to great danger when he decides to install the boiler on his own. Therefore, it is better to entrust the installation and connection of a gas water heater to professionals, and the owner should pay attention to a number of points:

installation of a boiler can only be carried out after obtaining permission from GorGaz. This will not be a problem if the gas boiler is installed on the site of an old gas water heater;
If you have never had a water heating device before, obtaining permission will take more time and effort. The purchased unit must comply with all existing standards. In addition, the boiler must be certified.

The structure of the geyser

Instantaneous gas water heaters consist of three main components:

gas burner device and gas removal system;
heat exchanger;
ignition and control module.

Structure of a water heating column with piezo ignition
All these units have several modifications and their layout gives different models with different characteristics. All this allows you to choose a unit to suit your own requirements, because you can only say which geyser is better by being tied to a specific situation.

Recommendations for choosing water heaters

Gas boilers are devices that pose a certain danger when used.
Therefore, you should approach the task of choosing them extremely responsibly. If you have planned to purchase a gas water heater, but your home does not have a chimney , then you should choose from units equipped with a closed chamber or equipped with a turbo hood. It is prohibited to install hybrid-coaxial chimneys in enclosed spaces. Their installation is usually carried out in boiler rooms or utility rooms with an effective ventilation system.

We recommend: Heated floors: water and electric

When choosing gas equipment for heating water, attention should also be paid to its power. It is optimal to buy a device that has a power/performance ratio of less than two units.

The most important thing when choosing gas equipment is safety. Before buying the selected device, you should make sure that it has protection against overheating and dry running. You also need to check that the boiler has draft and pressure sensors.

Heat exchanger

Water is heated while it flows through the heat exchanger. It is a metal pipe installed above the burner. The shape of the heat exchanger in a gas water heater is special - a pipe with fins is laid in a snake at the bottom, then a sheet of metal is installed around it, on top of which the pipe is wound in a spiral. Water flowing through this long path is heated by the heated metal.

This is what a heat exchanger for a gas water heater looks like

Heat exchangers are made from galvanized steel (the most budget option), stainless steel and copper. The best in terms of efficient heat transfer are copper. They are the most economical, but also expensive. The most durable ones are stainless steel, but they are much worse at heat transfer. Which gas water heater is better in this case is up to you to decide. Choose the quality that is more important to you.

If you decide to buy a gas water heater with a copper heat exchanger, do not try to find a cheap model. In order to reduce the price, manufacturers use low-quality copper, and the tubes are also made with thin walls. Such a heat exchanger will serve the warranty period, and then problems will begin - a leak will appear.

If you remove the casing, you will see fistulas in the tubes through which water drips. They are located mostly on the outside of the pipe, exactly in the place where condensation forms. If the pipe is of normal thickness, this is not a problem, but it quickly corrodes thin walls. Such a heat exchanger with a leak does not need to be replaced (it costs about 1/3 of the total price), it can be soldered. You will need refractory solder with a melting point of about 200°C, a powerful soldering iron and soldering flux. The technology of work is usual - clean the damaged area to bare metal, degrease, tin, and solder.

Advantages and disadvantages of gas water heaters

A gas instantaneous water heater has a number of undeniable advantages in comparison with other analogues:

comparatively cheap energy resources consumed – heating water with gas is cheaper than heating it with electricity;
unpretentiousness to the quality of heated water - scale does not form on the walls of the heat exchanger, unlike heating elements.

And given the frequent power outages and power surges that are typical for private homes, the use of electric water heaters becomes impractical. Plus, the discrepancy between current parameters in domestic power systems significantly reduces the efficiency of electrical equipment.

If we consider the disadvantages of gas water heaters, we would like to pay attention to the following features:

The water pressure in the cold water supply must correspond to the minimum established parameters of 0.25 atmospheres. The use of flow-type gas equipment for heating water on the upper floors of a high-rise building is not always possible due to low water pressure.
Due to the production of exhaust gases during fuel combustion, a chimney and a high-quality ventilation system are necessary.
Connection to the central gas supply line can only be made if all permitting documentation is available.

Typical breakdowns and how to fix them

Repairing a gas water heater is an activity for highly qualified specialists. However, some breakdowns can be fixed with your own hands. Before starting work, you need to close the water and gas supply taps. After this, you need to unscrew the mounting screws and remove the handles and speaker housing.

Here are some examples of when a gas water heater won't light up:

Water heaters with automatic ignition systems may run out of batteries. All you need to do is replace the batteries.
For water heaters that have a built-in generator, the piezoelectric element, electrode or power cable may malfunction. It is necessary to clean the contacts of the automatic ignition system, check the electrodes and wires for malfunctions. If all these steps do not help, you need to check and replace the power button and the piezoelectric element.
If there is no draft, you need to clean the ventilation; to do this, you should call a specialist.
If the pressure is insufficient, you should pay attention to the water supply or heater assembly. All that is needed is cleaning the pipes, washing or replacing filters.
If the gas water heater does not turn on, you should check and, if necessary, replace the membrane of the water unit. To do this, remove the water-gas block and, by unscrewing the screws, separate its water part. Before removing the rubber plate, it is important to remember its location. Then you need to clean the inside of the cap and install a new rubber part on the plate with the stem. It is better to replace the membrane with silicone, which lasts longer. Finally, you can tighten the screws (preferably diagonally).
Some gas devices have a knob for adjusting the water flow. If the column does not light up, you need to check how the mechanical switch is located. If the pressure is not large enough and the column does not start, you should set the knob to the leftmost position and switch to the right until the device turns on. You need to adjust the jet at startup.

Cost of water heaters

Prices for water heating devices depend on the brand, functionality and quality of the device. For example, prices for water heaters of the Ariston brand range from 4,200 rubles. up to 13,500 rub. For a minimal amount you can purchase a unit with a thermostat that changes the water temperature. This model is characterized by high thermal insulation, and the inside of the tank is coated with an anti-corrosion coating. In addition, this model heats water quite quickly.

For the maximum amount you can purchase a water heater with sufficiently high power and capacity. The tank has an anti-corrosion coating, quickly heats water, and has a beautiful design.

German gas water heaters are more expensive. The price of Bosh speakers ranges from 7,000 rubles. up to 80,000 rub. For 7,000 you can purchase a device with fairly high productivity and an improved security system. Fast water heating and overheating protection system. Materials of execution: stainless steel and copper.

For 80,000 rubles. You can purchase a fairly powerful and voluminous unit with many functions, made of high-quality materials.

Recently, Russian gas water heaters have begun to gain popularity. There are different reviews of Neva brand speakers. However, more and more buyers note the high quality and attractive design of gas devices of this brand. Gas water heaters "Neva" can be purchased for 6,000 - 11,000 rubles.

The cost of water heaters ranges from 2,000 rubles. up to 7,000 rub.

A gas water heater is a guarantee of comfort in any home. The main thing is to choose the most suitable option. And there will be no problems with the range of gas appliances.

Selection options

Once you have understood for yourself which gas water heater to choose based on its operating principle, it’s time to understand the important technical characteristics.

Power

The power indicator affects how quickly a certain volume of water will heat up. But it also affects gas consumption, and in the case of energy-dependent models, also electricity consumption. Therefore, the power should be optimal for specific conditions, and not underestimated or overestimated.

All equipment is divided into 3 categories:

low power - here the values will be from 17 to 19 kW;
medium - range from 22 to 24 kW;
high - power reaches 28-31 kW.

For a family of 3-4 people, medium-power equipment is suitable. If you need to choose a gas water heater for an apartment where a family of 1-2 people lives, then 17-19 kW will be just right. The best geyser for a private house with a large area and a large number of water intake points is 28-31 kW.

Type of burner

Which gas water heater is the most reliable, based on the type of burner? Let's consider both available options, their pros and cons:

Constant power. This is a standard scheme that was present in the very first models of gas water heaters until the development of modern systems. A constant power burner is characterized by inconsistent water pressure, requires manual adjustment, affects higher gas consumption, and it is not always convenient to set the desired water temperature.
Modulating. An excellent option, since it assumes several burner operating modes, which change automatically, based on the water pressure and its flow from different water intake points. Stability of pressure, temperature, and the absence of additional actions for the operation of the system are the undoubted advantages of modulating models. But their price, naturally, is somewhat higher.

Heat exchanger

The gas burner heat exchanger is one of the main working units of the system. Therefore, its device must be of high quality and reliable. The following materials are mainly used today:

Copper. Expensive water heaters are equipped with heat exchangers made of copper, which does not corrode, has high heat transfer, and is durable. The only negative is the price and heavy weight.
Steel. The best option based on the criteria of durability, cost, anti-corrosion properties and strength. Of course, in general its characteristics are somewhat inferior to copper, but for many this is not critical. The main thing is that the manufacturer you choose does not skimp on the manufacture of the heat exchanger and that its design has a good alloy base and thick walls.

Safety

Gas water heaters have the following elements in the device:

Traction sensor;
Temperature control sensor;
Flame sensor;
Gas sensor;
Overheating protection system.

Which boiler is better?

As can be concluded from the information above, a gas storage boiler, 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?

We recommend: Kiturami gas boiler: design, technical specifications, operating instructions and owner reviews

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 operating conditions (user requirements). Therefore, it is better to compare manufacturers with each other, the range of models of which, as a rule, have the same type of design solutions that are available or not available from competitors.

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

BAXI. The well-known 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. If necessary, it is possible to connect several boilers in parallel with an installed thermal power of 4 to 20 kW;
VAILLANT. The products of the famous German brand are highly reliable and durable. The domestic market offers models with tank capacities from 130 to 220 liters. The thermal power required 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 facilities in Russia (electric boilers of this brand are definitely produced here). The range is represented by household water heaters with a volume of 50-195 l, which allow wall and floor installation. Technical solutions and characteristics are similar to models from previously mentioned manufacturers, but the price is significantly lower. For comparison, the Ariston SGA 200R model with a volume of 195 liters costs approximately 38,000 rubles, while its analogues BAXI SAG3 190 and 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 wall-mounted boilers with tank volumes of 80, 120 and 150 liters. 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 MOR-FLO line of floor-standing boilers, made in the 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 have a long warranty period (6 years) at a fairly reasonable price: the 190-liter G62-75T75-4NOV has a price tag of 41,000 rubles.

Ten best water heaters

According to the type of combustion chamber, all water heaters are divided into two categories: with an open chamber or atmospheric, and with a closed chamber or turbocharged.

Atmospheric ones are considered more durable, since such devices do not have complex automation. Turbocharged ones operate using electricity and turn on even with minimal gas pressure, but they are more expensive.

Type of ignition

For the dispenser to start working, you need to light the gas. Older models were lit manually by holding a burning match to the igniter. Today such units are no longer on sale; they are a thing of the past. They have been replaced by others that operate in automatic or semi-automatic mode.

Piezo ignition

In geysers with a piezoelectric element, ignition occurs in a semi-automatic mode. There are two burners - main and pilot. The pilot burner is a small wick that burns continuously, whether there is hot water flow or not. The main burner turns on only when the tap opens. The rest of the time it is turned off.

The procedure for starting a gas water heater with piezo ignition is simple: press the button located on the front panel, a spark appears on the candles, which ignites the pilot burner. When the hot water tap opens, gas is supplied to the main burner and ignition occurs from the pilot burner. While water is being consumed, both burners are lit. The valve was closed, the gas supply to the main one stopped, only the pilot one was on again.

Piezo ignition device for geysers - a simple and inexpensive device

What are the advantages of geysers with piezoelectric elements? These are the cheapest models and usually have a mechanical control - a regulator that allows you to change the height of the flame, thereby regulating the temperature of the hot water. These models are non-volatile, which can be important for a summer residence.

There are more shortcomings and they are more serious. The wick burns (should burn) constantly while you are using the column, and this is gas consumption. Even if it is small, but constant, as a result, quite a decent amount accumulates in a month. So this is far from the most economical way to heat water. The second disadvantage is also associated with the burning of the wick. If it goes out, you will not be able to light the column. The wick goes out because it does not have enough oxygen to burn, or because backdraft periodically occurs in the chimney, which blows out the flame. Since there is a flame controller, this is not a big deal - the gas shuts off automatically, but having to light the pilot burner again is unpleasant.

Electric ignition

Automatic geysers have electric ignition. This is an electric spark generator that is activated when the tap is opened. The rest of the time the gas is not lit, which significantly saves fuel. There is an electric ignition powered by batteries, and there is one from a 220 V network. Which gas water heater is better for this parameter must be chosen depending on the circumstances.

If your lights go out frequently, it makes sense to choose a battery-powered model. As you understand, in this case you have to make sure that they don’t “sit down.” If there are no problems with electricity or there is a backup power source, it is better to choose a gas water heater operating from a 220 V network. Plug the cord into the outlet once and forget about it. Electricity consumption is negligible, so they have almost no impact on bills.

The electric ignition is controlled by a microprocessor

Gas water heaters are electronically controlled. A board with a microprocessor is installed in the case; the desired temperature is set from a small control panel (push-button or touch). A small liquid crystal screen is often installed here, which displays the current state of the equipment, the temperature of the water, if it is being heated. This type of geyser is the best if you value ease of use.

Disadvantages - higher price and power requirements. Electronics need a stable voltage of 220 V with small deviations of the order of 2 * 3 V. We cannot maintain such parameters, so in order for an automatic gas water heater to work for a long time, a stabilizer is required, and it is better not a relay, but an electronic one. It not only stabilizes the voltage, but also evens out the shape of the pulses, which is also very important for imported water heaters.
