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

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.

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 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 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 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.

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 in the summer. 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 of the chimney and ensuring sufficient ventilation in the room.

As for the boilers themselves, foreign-made models are presented on our market, which allows the user to hope for their 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.

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.

What is cheaper: gas or electric water heater?

Connection - an electric water heater differs from a gas water heater in that a project is not needed for its installation. A storage or flow-through electric boiler is as safe as possible. Electric water heating equipment can be installed in any room, regardless of the purpose and size of the room.

8	Tying the geyser with polypropylene or metal-plastic pipes	400
9	Installation of shut-off valves on a gas pipe	500
10	Removing an old gas boiler	400

Maintenance - the storage tank and column must be inspected every year, performing minor repairs. The magnesium anode in an electric water heater needs to be changed, and the heat exchanger in gas equipment must be cleaned of scale. Service costs vary. The price is largely influenced by the distance of the official representative office of the manufacturer from the place of residence of the owner of the water heating equipment, as well as the territorial affiliation of the brand of the water heater. German equipment will be more expensive to repair than Korean or Italian equipment.

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: Safety valve for a water heater: why is it needed, how to install

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.

The device and how the unit works

The appliances are not used for heating, but exclusively for heating water. For those who are planning to install a unit of this type, the operating principle of gas storage equipment is important.

First, the heat exchanger is heated, then the temperature of the liquid increases. The first is placed inside a metal tank made of a steel alloy (but the inner surface may be enameled).

The operating principle of a gas water heater.

The heat exchanger is a coil made of steel, cast iron or copper. It is heated by a gas burner. The design of the device also assumes the presence of pipes for water outlet and supply, and heat-insulating elements. A gas storage water heater must include a chimney.

The device is equipped with an ignition system and sensors that monitor the temperature and pressure in the system.

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.

Security systems

Everyone knows very well that natural gas is explosive. And its presence in the air negatively affects human health. Therefore, a good geyser must have the following security systems:

Flame presence control;
Control of traction;
Heat limitation;
Pressure meter.

The flame detection system operates on the basis of a thermocouple. The most advanced columns are equipped with ionization control, which is faster. If the flame goes out for some reason, the protection system will shut off the gas supply. It is also desirable to have a draft control system, which will prevent a gas explosion and leakage of combustion products into the room.

Heating limitation prevents overheating of the heat exchanger as a result of incorrect settings. If the column has a water pressure sensor, it will prevent the column from continuing to operate if the heat exchanger is damaged or there is a leak.

Here our recommendations will be the simplest - the more security systems on board the speaker, the higher the safety of users.

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.

Important nuances

Choosing the right geyser so that it functions smoothly for many years requires taking into account the following important nuances:

The heat exchanger must be made of copper.
The larger the flow diameter of the heat exchanger pipe, the less likely it is that it will need to be cleaned of scale and debris.
The water block should also be made of hard metal to prevent stripping of threads during regular membrane and filter replacement procedures.

Advice! Correct calculation of air exchange allows you to determine which column to choose in a particular case. This value is prescribed by sanitary standards, depends on the power of the unit and the volume of the room and shows how many times the atmosphere of the room in which the gas equipment is installed must be renewed within an hour.

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.

Review of the best manufacturers of gas water heating devices

In order for the long-awaited purchase to work for more than one year, you need to choose a water heating device from the most popular companies that offer geysers.

Ariston – Italian quality at reasonable prices. The speakers of this company are equipped with various additional functions: support for a given temperature, LCD display, 3 combustion power modes. Components and components are made from high-quality composite materials, which guarantee long service life and resistance of components to corrosion.

They do not heat up from the outside, have a protective coating and operate silently. The devices are characterized by high operating efficiency.

Geyser Junkers

Electrolux - decent quality Swedish equipment at the best price. Gas water heaters from this company have a power from 17 to 31 kW. The burner is made of stainless steel, and the heat exchanger is made of copper, which guarantees a long service life of such equipment. The geyser has a hydraulic type safety valve, which serves to protect the unit from overheating. Since geysers are equipped with a small number of nozzles, the equipment operates silently. Some models (for example, Electrolux GWH 265) are equipped with automatic flame adjustment to keep the coolant temperature constant even if the water pressure decreases.

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: Calculation of heating radiators, number of sections and battery power

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.

Main varieties

Gas instantaneous water heaters (columns) are small in size, making it possible to install them in small rooms (in the bathroom or kitchen). The purpose of the device is to quickly heat water passing through the heating element in the column. An important requirement for flow-through technology for stable operation is a gas pressure of 12 mbar. There are two types of gas flow heaters: with an open combustion chamber and a closed one. Both types have their advantages and disadvantages.

This is useful: what types of water heaters are there and how to repair them.

In a column with an open combustion chamber (atmospheric), when burning the burner, air coming from the room in which the unit is installed is used. The entry of oxygen and the exit of flue gases is carried out through the natural movement of air masses. Atmospheric instantaneous gas water heaters are equipped with a simple device without complex automation. They are considered reliable and durable in use.

In this video we will learn how to repair a gas heater:

A turbocharged column is better because during combustion it burns oxygen from the street (they have a coaxial chimney). These models have several advantages:

They use modulation types of burners with low gas consumption.
They can operate at low water pressure from 0.3 MPa.

Disadvantages include energy dependence and high cost. To ensure normal operation of the structure, the installation of a stabilizer and a UPS is required. If they are sufficiently equipped with automation, they may fail, as there are frequent power surges in the network.

Advantages and disadvantages

There are a large number of different types of water heating units. Everyone chooses according to their taste and capabilities.

Main advantages:

produces an unlimited volume of water compared to storage heaters;
compactness allows you to install it in a small room;
breakdowns of additional functions can be easily and inexpensively fixed;
maintenance is not labor-intensive (disassembling and cleaning will not be difficult);
using sensors, possible gas leaks are eliminated;
saving on fuel, since natural gas is much cheaper than electricity.

Different types of water heaters according to their technical design must be selected taking into account the conditions in which they will be installed. The characteristics of the room should be taken into account. To do this you need:

the presence of a chimney to remove combustion products;
take into account the volume of water for the required consumption, as well as the number of intake points;
is there free space for convenient use of the speaker;
matching the design of the equipment and the room.

It is better to invite a specialist to install the water heater. He will determine the draft and supply gas and water pipes. In addition to the positive aspects, there are also negative characteristics in the operation of a gas flow device:

installation must be carried out by a specialist;
for preventive purposes, carry out regular maintenance;
Carefully monitor the device to ensure that there are no possible leaks of explosive gas.

Types of ignition

The speakers differ in the automation of the ignition processes. It is divided into two types: automatic and semi-automatic. Automatic ignition is carried out by the device independently. Only one burner is built into the design. When the hot water tap opens, the flame ignites from the spark produced by the column. The power source can be electric ignition or batteries.

New types of dispensers have a hydraulic turbine that generates electricity when water is supplied, so the operation of the dispensers does not depend on the power supply. An electronic programmable unit is built in to regulate the water temperature.

Semi-automatic water heaters have two burners. The first one burns constantly and serves as an ignition wick. The flame is ignited using piezo ignition. The second (main) ignition occurs when the tap of the water supply system is opened. Each type of speaker is equipped with a security system. If the gas or water pressure is insufficient or the exhaust gases are poorly discharged, the device turns off and refuses to work.

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.

What points should you pay attention to when choosing a speaker?

An important and useful device in Russian realities will be the presence of a modulating burner: with a known variability in gas and water pressure, such a burner will smooth out pressure differences. No less important are related factors: the diameter of the pipes, their condition, as well as the condition of the plumbing in the house. The flame control function will also be useful: if the fire in the column goes out for any reason, such a system will automatically turn off the gas supply and completely eliminate the risk of explosion.

Many modern speakers are equipped with protection systems that completely ensure the safety of people and property in the apartment. Such systems protect against gas leaks if the fire goes out or does not ignite, or the draft in the chimney disappears, and protect equipment from overheating. Some models have protection against excess or insufficient water pressure.

Particular attention should be paid to the chimney, which will be connected to the selected water heater. By burning methane and thereby heating water, the column produces carbon dioxide, which needs to be disposed of somewhere

For this purpose, a chimney is connected to it. Heating appliances that supposedly do not produce carbon monoxide do emit some amount of it. Breathe small amounts of harmful substances or connect a full-fledged chimney? The decision remains with the owner of the equipment.

So, let's summarize. How to choose a geyser and what you need to pay attention to? When choosing a gas water heater, you need to take into account a number of important factors, including:

the number of points from which hot water can simultaneously flow in the apartment;
the condition of the plumbing equipment in the house;
technical characteristics of the most selected column (power and performance);
the cost of this or that equipment;
appearance of the column;
constant gas pressure in the gas pipeline and the diameter of the gas supply pipes;
parameters and design of the heater;
the minimum water pressure at which the column will work properly.

Additional Information

When choosing the best instantaneous gas water heaters for yourself, you need to take into account additional features, the availability of specific functions and options. The type of ignition is of great importance, on which the ease of use of the heater depends. Most models use the following options:

Mechanical. Piezoelements are used here. This requires constant operation of the igniter, which consumes gas. That is, there is an excess consumption of gas, although insignificant.
Rechargeable. Convenient elements in the form of AA batteries. Requires regular replacement or recharging.
Electric. Electrical connection required. In the event of a power outage, it will not be possible to light the column in this way.

Most users prefer batteries as the most convenient and independent option.

An important option is the ability to set the required temperature. Modern models do not require manual adjustment of the gas supply. All actions are carried out automatically, through sensors and electronic control. The current water heating value is displayed on the display located in front of the heater.

When it comes to choosing a gas water heater for your home, for many the issues of safe operation come first. All modern models are protected from overheating and equipped with a gas control system. The most advanced devices have 4-level protection: air draft, presence of flame in the burner, heat exchanger temperature and water circulation are controlled. The more such levels a device has, the safer its operation.
