Gas water heaters

These days, it is possible to provide hot water in the apartment in different ways, and heating devices are presented in a large variety. Among them, gas heaters are highly popular. They allow you to forget about interruptions in the flow of warm water and are more profitable than heaters that use other fuel.

Water enters the heat exchanger of the column from the water pipe. Inside the equipment, the water is affected by the heat from the gas burner. As the water moves through the curved tube of the heat exchanger above the burner, it is heated, after which it enters the outlet pipe and open faucet.

Offered these days water heaters running on natural gas, are very convenient in operation, quickly heat water and have good technical characteristics. Manufacturers improve the ignition system in such heaters and develop models with different power to offer customers a wide choice. In addition, in modern speakers there is a safety system, thanks to which the equipment serves for a long time and withstands different conditions of use.

The first speakers were distinguished by their quality, design and reliability. They could not be called economical, because the devices used a few decades ago wasted quite a lot of gas. Nor was such equipment safe, because it lacked sensors to ensure that the burner would turn off under unfavorable conditions of use, for example, if the water pressure was exceeded.

These speakers are among the most reliable devices. The spark in them is formed from the battery, represented by finger batteries. They have no additional buttons and you do not need to light a match to turn them on. You just open the faucet and get hot water.

In addition, this variant of the heater economically consumes gas fuel, because after closing the faucet in the device with electronic ignition simultaneously stops burning. While in devices with piezo ignition, even when the faucet is closed, the spark plug continues to burn.

Such speakers are gradually being replaced by more modern ones, because to turn them on, you first have to bring a lighter or a match to the igniter, and then turn the appropriate knob.

At the heart of the operation of this type of speakers is the piezoelectric effect, the essence of which lies in the transformation of the mechanical action into an electrical charge. Pressing the button, located on the panel of the device, you will cause the formation of a spark from the piezoelectric element, which will cause the igniter to light up. Then the speaker will work automatically - after opening the faucet from it in just a few seconds the heated water will begin to flow.

Although flow-through models of gas water heaters are the most common, there are also storage tanks, the operation of which is similar to the functioning of the boiler. However, in our country they almost never occur due to such disadvantages as large size, less convenient use and high price.

Buying a speaker, pay attention to such parameters:

• Dimensions.
• Type of ignition.
• The power of the apparatus.
• The performance of the model. Measured in liters of hot water heated by the device per minute.
• Gas flow rate.
• Type of burner. More practical and profitable will be the device, in which the burner power can be modulated.
• Safety system.
• Drainage of combustion products. It can be turbine (the pipe goes directly to the street) or chimney.
• Weight of the equipment.

The power of this type of water heaters, such as a gas water heater, determines the rate of water heating inside the device. The more powerful the device will be, the more water it will manage to heat in a shorter time period. For example, with the most powerful speaker you can wash dishes and take a shower at the same time.

If you need to bring hot water to only one point, you can limit yourself to a device with a capacity of up to 20 kW. The capacity of such a speaker will be up to 11 liters of heated water per minute. If you want to get hot water in several points, the capacity of the device should be higher - at least 20-26 kW.
