Hardware Features

Gas water heaters for the home have several advantages compared to devices powered by electricity:

1. Simplicity of installation and commissioning;
2. The cost of gas is much less than the price of electricity;
3. Lack of strict requirements regarding water hardness;
4. Compact design;
5. Possibility of heating an unlimited amount of water;
6. Reliability and durability of use.

Important! The flowing gas heater turns on automatically, which occurs simultaneously with the turn of the tap with hot water you performed, and the equipment is also turned off automatically.

However, like any device, gas water heaters have several disadvantages:

• Required installation of the chimney and equipment of a high-quality ventilation system, which will be responsible for the diversion of gas combustion products outside your residential premises
• The water pressure in the system should be at least 0.25 atmospheres - about one and a half liters per minute;
• To install a gas flowing water heater, you need to collect a number of permits and conclusions from the relevant services.

Geyser Safety

Gas heaters are the safest devices for arranging hot water in a residential building. Their reliability is ensured by a special system that protects the structure from overheating.

Each column is equipped with the following safety devices:

• Sensor available traction. It performs the function of temperature control, and in case of its excessive increase, gives a command to close the gas supply valve.
• Control unit. Due to the convenient control panel, the user has the ability to regulate all functions and ongoing processes - temperature, pressure, power, etc.
• Duct sensor. It controls the temperature of the water flow during overheating - it is used to shut off gas supply to the system.
• Electrode for monitoring the strength of the flame. Since there is no constantly working wick in the design of the water heater, the least amount of combustion products enters the environment.
• Safety valve. With the help of this element, the presence of a flame in the burner is monitored, and accordingly, protection against emergency gas escape is ensured.

How to choose gas flow water heaters?

All modern devices for heating water when using gas do not require manual ignition of the wick, but start work due to the automation installed in the design.

Type of ignition

There are several basic ignition options:

• due to connection to the power supply network;
• due to the mounted piezoelectric element;
• thanks to batteries or the use of a battery;
• thanks to the integrated hydro generator.

Important! The most economical are the last two types of construction.

Type of combustion chamber

Also, gas flow water heaters differ in the type of structure of the combustion chamber, which may have an open or closed design.

Important! Closed cameras are more environmentally friendly and safe to use.

Power

The main characteristic by which you can choose the right gas flow water heater is the power of the device. Here the conditions will be as follows:

• 19 kilowatts provide the room with about 5 liters of water heated to a temperature of 50 degrees;
• 24 kilowatt devices provide about 7 liters of hot tap water;
• the most powerful speakers for 28 kilowatts - from 8 liters.

When deciding how to choose a gas water heater, give preference to devices with the capacity that is necessary for your family, because this indicator has a direct impact on the pricing of the installation. You will find detailed information about the best models in our rating of geysers.

Important! For a small family of 1-2 people, it will be enough to install a column with a capacity of 19 kW, and if you use several points of water intake, then there may be a need for more powerful equipment.

Useful Tips

When installing a gas instantaneous water heater, follow the instructions and the sequence of actions:

1. Check the water supply pressure, which should not be less than 0.1 atmospheres;
2. The mounting location of the equipment must be made of non-flammable building materials.
3. The minimum area of ​​the installation room should be more than 6 m2 for the closed design of the combustion chamber and 8 m2 for open chambers.
4. Organize a decent level of ventilation in the room where the gas instantaneous water heater will be installed.
5. Each device is accompanied by detailed instructions on the scheme and method of its connection and installation.

Installation of the instantaneous water heater is carried out according to the following sequence:

• Mounting the hood.
• Column setup.
• Connection to the central water supply.
• Installation of nozzles for the exit of heated water.
• Connection of equipment to the gas supply system.
