Rating of the TOP 15 best geysers of 2020-2021

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.

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.

First aid

Before looking for a breakdown and calling a repairman, check that all conditions for normal operation of the column are met.

What to look for:

• If the water is not hot enough, check the temperature regulator and, if necessary, turn it to the desired value;
• If the device is working at maximum, the pressure is very good, but you need to make the water hotter, open the tap halfway;
• Check whether the gas tap is fully open, especially if you recently turned off the gas due to repairs or departure;
• If the dispenser operates on liquid gas, call a technician to inspect the cylinder and check its serviceability;
• Check to see if the cold water is turned on anywhere;
• Compare the temperature of the hose at the dispenser and the mixer. If it is different, the tap needs to be cleaned;
• Check if the filters are clogged.

If all of the above is working properly, but the water heating system still does not work well, you need to look for a breakdown in the device itself.

Gas consumption

The average user is interested in how much fuel his dispenser consumes. If the device operates from a centralized gas supply, you need to know how many cubic meters are consumed per unit of time; If it's propane, I wonder how long one tank will last? Costs depend on various characteristics and, above all, on thermal power. An example of calculating propane-butane consumption. Initial data:

• specific heat of combustion - 14 kW/h;
• Efficiency - about 92%;
• burning 1 kg of propane-butane mixture gives 12.9 kW/h.

Let us have a heater that produces 5 liters of hot water per minute, and fuel consumption is 1.5 kg per hour. A 50 liter cylinder contains 42 liters or 23 kg of propane-butane. By making simple mathematical calculations, you can find out that one cylinder is enough to heat 4,600 liters of water. Translated into hours, this is a little over 15 hours of continuous heating. If you use hot water for 2 hours a day, you will need 4 cylinders per month.

A conversion kit for Bosch speakers can be purchased from an authorized service center.

If it is necessary to carry out work on reconfiguring equipment, replacing collector nozzles and assessing the tightness of joints, they must be done strictly according to the rules. The nozzles must be smaller in diameter: as in gas stoves, the pressure produced by liquefied gas reducers is 2–3 times higher than when natural gas is supplied through pipes. At the same time, the calorific value of liquid fuel is 1.5 times greater than that of natural gas.

The equipment must be marked with a refurbishment date - day, month and year. The type of gas suitable for use is also indicated.

The connection diagram of the cylinder to the main valve requires it to have a reducer with pressure stabilization of 300 mm of water. Art. and a minimum steam phase productivity of one cubic meter per hour.

Parameters of the hose connecting gas equipment to the fuel tank:

• 250 cm - minimum length;
• 1.2 cm is the least permissible inner diameter of the tube.

Please note that on online forums there is information of the following nature: if you reconfigure the column correctly and carry out the work without flaws, problems with water pressure may arise and the column will not start. Then you will need to additionally install a pressure pump

When installing a shut-off valve, remember that it must be easy to access so that in the event of an emergency the user can quickly turn it off.

After completing the installation work, check the tightness of the connections and conduct a test run of the equipment.

Instructions. Conversion of the Neva 4511 gas water heater to liquefied gas

The gas column has jets with a diameter of 1.28 mm. This set of nozzles is installed in the burner ramp for operation on natural gas with a pressure of 130 mm. water Art. (130 mbar). The ramp at the Neva 4511 gas water heater is ten-sectional, i.e. The ramp includes 10 nozzles.

The set of liquefied gas nozzles we offer contains 10 nozzles with a diameter of 0.75 mm.

The offered kit is only suitable for this model,

because, for example, the Neva 4510 gas water heater has a ramp that is simply of a different design. Moreover, this model of Neva 4511 has been studied quite well by us. It is easy to install, repair and maintain. When converted to liquefied gas, the dispenser consumes about a kilogram of gas per hour of operation. Now you will see for yourself that altering the ramp will not take much time. To move the column we need a Phillips screwdriver and an adjustable wrench (38 mm). The column itself does not need to be dismantled at all.

Begin

First you need to separate the ramp. An ignition electrode (candle) and a flame presence (ionization) sensor are attached to the ramp. Separate them by unscrewing two screws.

In the photo they are indicated by number No. 1. After separating the sensor and spark plug from the ramp, you need to remove four self-tapping screws (No. 2), which secure the burner ramp.

After separating them, take an adjustable wrench and unscrew the ramp nut from the gas column assembly.

The ramp is in our hands. After the ramp is in our hands, it is best to turn out the jets with a 7 mm socket so as not to damage the splines when tightening the new nozzles with pliers or an open-end wrench (the wrench is the same as the 7 mm socket). As you can see, replacing the nozzles requires almost nothing from your brain.

Now we will understand the principle of operation of an instantaneous gas water heater using liquefied gas (also known as bottled gas). Let's see what advantages such boilers have and how to install them (install). Finally, let's look at the rating of manufacturers who produce the best models on the market.

Breakage Prevention

To avoid problems with the operation of the geyser, it is necessary to carry out its maintenance at least once a year . It is recommended to call professionals for these procedures, but if you want to save money and perform these steps yourself, you need to disassemble the device, first turning off the gas supply, and thoroughly clean the inside with a brush or rag. To improve the effect, you can use a vacuum cleaner.

Advice! In addition to the water heater, you need to inspect and clean the chimney, since if it is clogged, even a clean water heater will not work. In addition to removing soot and soot, you need to periodically clean the heat exchanger from scale, especially if the pilot light is regularly lit during the day.

So, if a geyser does not heat water well or does not heat it at all, it is necessary to diagnose the device to identify the cause of the malfunction. This problem can cause many breakdowns of this type of water heater, many of which occur due to the lack of regular preventive maintenance of the device. Once a malfunction is detected, you can try to fix it yourself or seek help from specialists if you are not confident in your own abilities.

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.

Failure Prevention Measures

To reduce the likelihood of geyser malfunctions and safely enjoy hot water, it is necessary to carry out periodic maintenance. You can do the work yourself or use professional services.

Prevention involves disassembling and thoroughly cleaning the gas water heater. We have provided a detailed description of the manual service process in this material.

Periodic maintenance and cleaning of the chimney will extend the life of the gas water heater.

When carrying out maintenance work, do not forget about the chimney. When the channel for discharging combustion products becomes clogged with soot and foreign objects, the protection is triggered and the water heater is turned off.

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;

Are there turbocharged models?

To heat water, you can use a turbocharged water heater. Such devices do not require a traditional vertical chimney; combustion products are discharged through a coaxial pipe led through the wall. It also supplies air to the closed firebox to maintain the combustion process. Turbocharged speakers have disadvantages: you need to make a hole in the pipe, ask the consent of neighbors above to install the equipment, the device is noisy due to the operation of the turbine. Plus, when working on propane-butane, you will also need to place a cylinder in the room. An important advantage of turbocharged versions is versatility; they can be placed in any room, since a chimney is not needed

The second important advantage is that they do not “eat up” the home air.

Principle of operation

The main function of geysers is to heat water in the shortest possible time. It looks like a housing in which the combustion chamber is located.

In a column powered by liquefied gas, water is heated as it flows through a heat exchanger, which in turn is heated by the burner. In addition, the device contains such elements as: a water cooling system, a control unit, temperature, pressure and draft sensors. Thanks to the electronic security system, the operation of the column is monitored throughout its entire operation.
