Over time, every owner of a gas water heater has a need to clean it. With proper maintenance and conditioning of the equipment, the need for cleaning is much less frequent. But even with such care, the heat exchanger will become covered with a coating of lime, and soot and soot will settle on the burner.

There are two options: call a specialist to do all the work for you, or clean the gas water heater yourself. In this article we will look at how to clean a gas water heater yourself. Next: the principle of operation of the gas water heater, the reasons and signs of the appearance of lime on the heat exchanger and how to clean the gas water heater.

The principle of operation of a gas water heater. A geyser is a simple device for heating water for domestic purposes. Depending on the manufacturer and model, components may vary, but the concept is the same:

The heat exchanger is connected to the water supply system. A burner is installed under it, which is connected to a gas pipe. The heat exchanger is filled with water from the system, the burner is turned on, and the water is heated. Smoke and other gas combustion products exit through the chimney. Based on its operating principle, a geyser can be called a kind of teapot.

The latest models of speakers are equipped with an automated burner, that is, it does not need to be ignited manually, as was the case before. This made the burners more economical and safer. The top of the geyser is covered with a housing/protective casing into which the control panel is built. Using the latter, you can regulate the temperature of water heating and the intensity of gas combustion.There are models with additional adjustable indicators.

Reasons for the appearance of scale in the heat exchanger. Scale appears during the use of the column - when heating water, especially poorly filtered water; Hard sediment is released, which is deposited inside the heat exchanger, forming a layer of scale, clogging pipes and generally worsening water heating. There is nothing you can do about this, you can only clean the gas water heater regularly.

Signs that the gas water heater needs to be cleaned:

• The maximum hot water pressure is less than the maximum cold water pressure
• After opening the tap (hot water), the burner goes out
• The device does not turn on
• Water temperature is lower than it was before
• Water takes a long time to heat up

Before you start cleaning, make sure that the problem is not with the stopcock. Its breakdown may also be the cause of some of these problems.

How to clean a gas water heater yourself? To do this, it is necessary to dismantle the heat exchanger. To do this, first turn off the gas and water supply to the device.

To avoid problems when dismantling the device, get the instructions. If you lost it, it's okay.

Next you will need tools:

• Metal clamp
• Plastic hose (from 1.5 meters) or large container
• Paronite gaskets
• Screwdrivers (phillips and straight)
• Adjustable and pipe wrenches

First you need to drain the water from the heat exchanger. To do this, connect the prepared hose to the heat exchanger and open the water supply. The next step is to remove the column frame/casing. Be careful not to damage the control panel when removing it. The cleaning filter is secured with a nut and must be removed using an adjustable wrench. After this, it must be washed and dried. If the filter is damaged, replace it.Disconnect the device from the pipes, remove the heat exchanger and remove it from its hinges. During the operation of the gas water heater, various substances and elements are deposited in the heat exchanger. Getting some of them on the floor, arm, leg or other part of the body will cause negative consequences, so place the device in a container (preferably with detergent) to allow the substances to settle and drain.

And now the main stage of cleaning. You will need a cleaner or a solution of it. Some people advise using soda (Sprite or Pepsi), but the effectiveness of this method has not been proven, so it is better to use classic remedies - “Antinakipin”, household vinegar (9%) or citric acid (100 grams per liter of water).

Under no circumstances use its essence instead of household vinegar. These are different substances. The essence has high acidity - it will corrode copper pipes.

Turn the heat exchanger upside down and pour 0.5-1 liter of cleaner into it. Shake the device and leave for 15 minutes. If you are using a specialized detergent, follow its instructions. Drain the solution, connect a hose to the heat exchanger on one side, and connect it to a water supply pipe on the other. Open the pipe tap and flush the inside of the heat exchanger. Run the water until it comes out clean. To be on the safe side, do several of these washes.

The gas water heater has been washed. All that remains is to put it back together:

• Connect the heat exchanger to the water supply, treat all connections with lubricant, and replace the gaskets.
• Install a water purification filter.
• Put on the frame/casing.
• Connect the device to the water and gas supply pipes.
• Open the taps.
• Check the quality of connections.
• Carry out a test run of the gas water heater.
