Install instantaneous water heaters began in times of lack of hot water. Old-style models are still found in some “Stalinka” and “Khrushchev”. However, residents of modern houses do not refuse to install heating equipment, which is associated with seasonal shutdowns.
It should only be taken into account that the models of the old and new samples differ somewhat in the type of control. How to use a gas column correctly? If you have any difficulties with this, then our article will help to solve them.
The principle of operation of technology
It is easier to remember the rules for using the device when you understand its device. Regardless of the manufacturer, all geysers – “Neva”,“ Astra ”and others – have the same design. Only the location of the nodes can change.
Main knots:
- Heat exchanger;
- Collector for removal of gases;
- Ignition unit;
- Burner;
- Water and gas fittings.
The lining of the column is made in the form of a metal casing – in some models it has a viewing window. On the panel there are regulators of power and temperature. Electronic control is complemented by a display.
Ignition unit. Depending on the type of ignition the product hasPiezo ignition or electronic battery activation button.
- semi-automatic models. Piezo ignition can be started in different ways. In some cases, you need to hold the button and press the power regulator. The wick will burn until you turn off the device yourself. It is recommended to turn off the burner after use or when leaving the house. So you can save gas and extend the life of the device.
- Automatic equipment is more expensive, but it is economical in operation. The wick does not burn constantly. The burner ignites only when the mixer is opened and goes out when it is closed. The electric charge is sent by batteries or a turbine. Batteries need to be changed periodically, and for the normal operation of the turbine, it is necessary to ensure stable pressure in the line.
Electronic devices can be equipped with a flame regulator. With a reduced pressure, the modulator allows you to adjust the heating power so as to obtain the desired water heating temperature.
Outlet manifold. Situated at the top. Pipes are connected to the branch pipe for the removal of combustion products to the street. In devices with a closed combustion chamber, the collector is located below and is equipped with a fan for forced removal of burning. These are turbocharged models such as Neva Turbo, Neva Lux 8224, Bosch WTD.
Columns of the trademark “Astra” and “Oasis” are produced only with an open combustion chamber.
Heat exchanger (radiator) is the main part in the water heater. Water flows through its tubes, which is heated by a burner. A high-quality radiator is made of pure copper. If impurities are added to the alloy, then the knot quickly burns out and leaks. Read the article “Heat exchanger for gas column”to learn more about his device.
Burner located under the radiator. A reliable body must be made of steel. The part distributes the flame through the nozzles for uniform heating of the heat exchanger.
Gas unit may be on top of the water (in older models) or to the right of it. Operation is controlled by turning the gas on and off.
water block located nearby, thanks to it fuel enters the system. When water is started, pressure is created in the system, which causes the rubber membrane to bend. She pushes the stem, which turns the fuel valve.
An ignition device is located near the burner. Also, the equipment is equipped with protection sensors:
- The draft sensor monitors the presence of draft in the system;
- Ionization sensor – control of the presence of a flame;
- Thermostat – temperature measurement, protection against overheating over 90 degrees.
When one of the sensors is triggered, the device turns off.

Features of operation
There are a number of regulations and rules according to which the use of gas equipment is allowed. Consider the basic requirements for open type columns:
- It is impossible to start work in the absence of draft in the chimney or in the presence of reverse draft;
- It is not allowed to turn on and carry out ignition without studying the operating instructions;
- For normal operation, natural ventilation is necessary (window, window);
- It is forbidden to change the design of the equipment by yourself.
For a long service life of the device, it is recommended not to turn on the heating above 55 degrees, and also not to mix hot and cold streams on the mixer. This leads to the rapid deposition of scale.
Columns with an open combustion chamber are most at risk of gas leakage. If you smell, then:
- Close the valve;
- Open windows and ventilate the room;
- Do not start a fire until the room is completely ventilated;
- Contact the repair service.
Before starting the appliance, check for draft in the chimney.
How to properly check
There are two “popular” ways to check:
- Take a piece of paper and bring it to the chimney or ventilation. If the sheet is tightening, then the mine is working properly. If it falls, then you need to clean the hole.
- Light a match and bring it to the viewing window. Does the flame deflect to the side? Then you can start the column. If it burns steadily, check the chimney.
It also happens that everything is in order with the mine, but there is no traction. Perhaps the room is not ventilated, so there is no air flow for combustion.
How to turn on the water heater
Before turning on any equipment, there must be water in the heat exchanger. Therefore, the water valve must be opened first.
Electrical Models:
- Insert the batteries into the battery compartment;
- In some cases, you need to turn the power or temperature toggle switch;
- Open the gas valve;
- Turn on the mixer at the hot position, which will cause ignition.
With a long break in the operation of the device, an air lock forms inside, due to which the burner does not ignite the first time. Way out: open and close the mixer several times until ignition occurs.
Semi-automatic devices:
- Start the fuel supply;
- Set the power and hold the piezo ignition button until the wick ignites;
- When the water is turned on, the burner will light up.
Launching modern technology is easy. But what about the old product?
Column ignition obsolete type
A device with manual ignition is considered obsolete. The design provides for constant burning of the wick and manual shutdown. Ignition occurs from a burning match, less often with the help of a piezo ignition. These include: “Iskra KGI-56”, series L, GVA, VPG. They are equipped with a turn signal or a lever to regulate the temperature.
The principle of operation is the same as that of modern models. The only difference is in the features of turning on the heating. If you are launching for the first time, then you should know that:
- The room with the column must have a constant supply of air. This is essential to keep the flame burning. Therefore, a gap of 5 cm is provided in the kitchen doors from below. If plastic windows are installed, a ventilation valve is required;
- Traction should be checked regularly;
- Check the condition of the gas valve. Open it and anoint the joints with soapy water. If bubbles appear, then there is a leak.
For ignition, it is more convenient to use long matches that reach the igniter well.
Launch of KGI-56
Turn the fuel and water valves. Now turn the left knob all the way to the left. Hold the button of the solenoid valve, if provided in the product. Continuing to press the button, ignite the igniter with a match. After that:
- Open the hot water faucet;
- Turn the other knob to the left to ignite the burner.
Done, you can go take a shower.
Switching on devices such as L, GVA, HSV
Start as with other types by supplying gas and water. Move the handle on the panel to the first position. Press the valve actuation button and bring a match to the igniter. Hold the button for another 10 seconds. In the same way as in the first case, turn on the tap and quickly turn the regulator to the maximum mark. After ignition, you can start using.
You can turn off the technique by turning the lever until the wick is extinguished. It is advisable to do this at night and before leaving home.
Use the water heater correctly for the long life of the device and your own safety. Once a year, carry out preventive inspections of the product, clean the parts from scale.
