We will tell you how to choose a geyser in order to purchase the ideal unit. Our proposed article describes all the criteria that can influence the choice of gas wall-mounted equipment. We present popular models among consumers from proven manufacturers.

Rating of the TOP 15 best geysers of 2021-2022

How to choose a gas water heater?

The main criteria that must be assessed when choosing a column:

1. Power . The parameter determines the water productivity of the device. The higher the power, the more hot water can be supplied to more points.
2. Inlet pressure . Affects the ability to supply water at low pressure. Many modern models allow water supply at low flow rates.
3. Safety . The dispensers are equipped with a protection system against overheating and freezing, as well as a sensor to turn off the unit and stop the gas supply in the event of a leak.

What elements should you pay attention to?

When choosing a column, you should give preference to models with a copper heat exchanger. It can be covered with solder, but should not be made of thin tin. Most often, models from Chinese manufacturers have tin heat exchangers. The service life of such speakers does not exceed three years.

Regardless of the ignition method, an automatic gas water heater begins to work when water passes through the water block. If problems arise with the spark supply, then the reason, first of all, should be looked for in the block (+)

Low cost is achieved due to the cheap quality of the metal, which burns out over time. This leads to the need to purchase a new gas water heater.

Another important characteristic of the heat exchanger is the internal diameter of the tubes. The wider the tube, the less often it is necessary to clean the heat exchanger from scale and small debris from old water pipes.

This is what a low-quality heat exchanger looks like, which is installed on cheap models of instantaneous water heaters. Inside it is clear that the metal is not made of copper and is an alloy of unknown origin

Another important detail is the water block of the column. This element must be made of metal. There are models made of plastic.

This is what a high-quality heat exchanger looks like, one that will last more than five years. Visually you can see that it is made of copper and has sufficient thickness. Some manufacturers coat this element with solder or other coating.

Since the block contains a membrane and a mesh filter inside, which need to be changed, frequent unscrewing spoils the plastic thread and leads to the need to completely replace the water block.

Safety is the most important parameter

Both natural gas itself and its combustion products can pose a serious danger in case of failure. To eliminate undesirable phenomena, geysers today are equipped with the following systems:

1. Flame control: when the burner goes out, the ionization sensor is triggered, which immediately sends a command to close the gas valve. In systems with a pilot burner, a thermocouple is additionally installed: if the wick goes out, it will cool down and close the valve.
2. Draft control: special sensors detect the movement of air flow in the chimney. As soon as it weakens or changes direction, the gas supply is cut off.
3. Heat limiter: As the name suggests, this mechanism prevents the water from overheating, which can lead to scale formation and injury to the user.
4. Emergency valve.

This element discharges water if it nevertheless heats up too much and its pressure begins to threaten the integrity of the heat exchanger.

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.

Reviews

The topic of choosing a geyser is discussed quite actively by users.
The favorites, as one would expect, are German units from Bosch and Vaillant.

However, a potential buyer should take into account the high cost of repairs.

It is not recommended to buy Electrolux, which was popular at one time - their quality has noticeably deteriorated.

Chinese speakers are recommended to be purchased with great caution: in many models, instead of a copper heat exchanger, a steel one is installed.

Many forum participants are owners of Neva brand speakers. The quality and reliability of this speaker are quite acceptable. Unexpected “surprises” occasionally happen, but German devices are also susceptible to this.

The very expensive Mora speakers are considered the most reliable; their heat exchangers come with a 10-year warranty.

Here is a table comparing the two types of models:

Thus, in small families it is quite possible to use an instantaneous water heater, and in a spacious house it is no longer possible to do without storage equipment.

Advantages and disadvantages of geysers

The advantages of a gas water heater include::

• provision of unlimited hot water;
• large selection of equipment at budget prices;
• undemanding water pressure for most devices;
• compact dimensions allow you to install the equipment in a small apartment;
• possibility of repair if parts break;
• significant savings, since gas costs less than electricity.

There are fewer disadvantages of a gas water heater:

• for the safe operation of the equipment, it is necessary to ensure the supply of fresh air and the organization of exhaust gas removal;
• the need for regular maintenance;
• costs of design documentation for installing a column.

Let's sum it up

The cost of gas water heaters is approximately the same as electric models of similar level and build quality. Yes, when installing them you will have to focus on serious requirements, including the presence of not only ventilation, but also a chimney. However, in the future, gas equipment will not only provide you with hot water all year round, but will also help you save on heating it. As for the cost of the column, it all depends on its performance, thermal power, as well as other characteristics of the equipment. Budget models are offered for 5000, premium ones - from 50 thousand.

Operating principle of a geyser

Modern speakers have been improved, so the principle of operation is much simpler than that of outdated models. To start, you need to open the mixer tap.

Immediately after this:

• water enters the unit, opening the valve for gas supply;
• the flame ignites automatically;
• hot water is directed to the mixer;
• the waste product is discharged through a chimney or coaxial pipe;
• after closing the tap, the supply of water and fuel stops.
