The benefit of the use of gas water heater type

The problem of getting hot water is relevant among residents of the private sector. Quite often, homeowners use gas water heaters of storage type. Although this variant of the heater is more expensive, it pays for itself faster during operation: gas is many times cheaper than electricity.

Design and functionality

Heating takes place in pretty capacious tank, which is the main part of the whole structure.Its size ranges from 50 to 300 liters. Heating takes place with heat exchanger, the products of combustion are removed from the product with the help of an outlet pipe. Special sensors are also available, whose duties include monitoring of various parameters, heat insulating elements, an ignition system, cold supply pipes and heated water output.

The boiler is filled with water automatically. When cold water enters the tank, the gas supply to the burner is turned on, the heat flow resulting from this comes out of the product through a pipe of a special design (with a turbulator), heating the volume of water along the way. When the set value is reached, the temperature sensor shuts off the gas and the heating stops.

What is the difference of such a water heater from a gas column? The storage boiler gradually heats up the volume of water poured into it, and only when it reaches the temperature set by the consumer can it be used. Geyser heats the water immediately, as it works on the principle of flow heater. The only thing that unites both devices is that they use gas as a source of heat.

Types of boilers

Specialists classify such household appliances according to several criteria:

1. Type of combustion chamber - open or closed.
2. The ignition system is from a piezoelectric element or an electrical home network.
3. According to the installation method - on the floor or wall version.

Next, we take a closer look at all the varieties of the above products.

With an open combustion chamber

An open-type gas water heater is equipped with a similar combustion chamber. Their work is carried out according to the principle: oxygen, which is so necessary for stable operation, comes directly from the room where the boiler is located. All products of combustion are removed through chimney, which the user must install in advance.

The cost of this type of water heater is cheaper, but the arrangement of the chimney system will cost you a lot of money, which does not attract users.

With closed combustion chamber

A boiler that uses forced traction is considered by experts to be a more economical option for placement in their home: its closed chamber has a special system for the removal of combustion products using powerful pump. This view does not require a separate ventilation system, because they do not use the air from the room for sustainable combustion - this fact becomes decisive when homeowners choose private buildings.

With piezo element

To start a modern gas water heater, matches or a lighter are no longer needed - there is a special button on each product, when pressed, the unit starts working. Products of this class are equipped with a piezoelectric element, which carries out the burning of gas. Many users consider this an atavism, an outdated option, but these boilers do not lose their popularity due to the low price.

Electrically ignited

Some homeowners are looking to purchase the latest model of gas boiler with the newest system. auto startwhich works independently - it is only necessary to open to you the crane. Similar models are much more convenient to use and very economical use of blue fuel, and the piezoelectric element can operate on electric power or batteries like Mars.

Outdoor option

The installation of a gas water heater on the floor is carried out because of rather large dimensions and weight: the product tank can hold 100–300 liters of water.Before you buy such a massive device, you need to equip a place for it - ideal in a separate roomwhere you can easily bring gas. Such boilers are bought by the owners of private houses to provide the whole family with hot water all year round, it would be problematic to place such a giant in the apartment of a city high-rise building.

Placement on the wall

As a rule, with this option, the water heaters have a more compact look: they are placed in the bathroom over the sink or toilet, which allows users to save space and use it more efficiently. These water heaters are designed for a small amount, so they can be installed in a city apartment of any size - the product will provide you with hot water, while not taking up much space.

What volume to choose

To choose a gas water heater of the storage type, which is ideal for your family, you need to know the flow of hot water per person. Experts claim that this figure is in the limit of 50-70 liters. daily consumption. Manufacturers of similar equipment produce various options with a volume of up to 300 liters. Therefore, it will not be so difficult to choose the necessary option.

When a water heater is purchased for a family living in their own home outside the city, then it is necessary to consider options not lower than 150 liters - such a volume can satisfy the needs for personal hygiene of all households. For those who doubt the validity of this statement, let's do some small calculations:

• take a bath - at least 150;
• shower - 50-100;
• morning hygiene - 15 liters;
• for washing dishes - no more than 30 liters.

Now all this multiply by family members - the result is unlikely to please you.

The volume of boilers from 200 liters is considered the best option for a large family with small children.

Advanced device selection options

Choosing an accumulative gas boiler, you should pay attention to the following important parameters.

Rated power

This indicator for gas products starts at 4-6 kW: in a boiler with a tank capacity of at least 150 liters, burners with a capacity of 7 kW are installed - it takes only about an hour to heat the entire volume. In an electric boiler of similar parameters, heating takes from 2 to 4 hours. Here the decisive factor is that gas is much cheaper, and there are other nuances in operation in favor of the gas option.

Manufacturing material

A tank of modern products is made of plain steel coated with special compounds or very expensive stainless steel. Each option has its pros and cons.

The first option is much cheaper than the second, but when choosing the user, it is necessary to take into account the fact that the first tank has thinner walls, which, when frequent water hammering occurs in the water supply system, is of primary importance. Stainless steel more resistant to corrosion, and special enamel coating can crack with time - the container quickly rusts and becomes unsuitable for use.

When different sprays are applied from titanium to glass porcelain, then the service life of the container has different time values, but the composition of the coating has a strong influence on the final cost of the product. There is another nuance here: from the frequent temperature difference microcracks appear over time, to prevent their occurrence, the user must adjust the temperature not exceeding 60⁰C. Sometimes, to prevent the development of various bacteria, it is necessary to warm the water almost to the boil.

Today, the most reliable are boilers with stainless steel tanks.Their warranty is 7-10 years, while glass-porcelain coated tanks have a total of no more than 12 months.

Magnesium anode

All boilers are equipped with such a device, the technical name of it - electrochemical protection with a sacrificial anode, which is made mainly from magnesium, sometimes from zinc. The anode gradually dissolves due to oxidation, ensuring reliable protection of the inner surface of the tank against corrosion. Replacement also depends on the structure of water: it is changed at least once a year for tanks with spraying, and when a stainless steel tank is installed, it is almost not necessary to change the anode. When buying, always ask about the presence of a magnesium device inside the product or find similar information in the instruction manual.

Frame layout and installation

Installation gas equipment is strictly regulated, so you cannot do without a specialist with the appropriate admission - otherwise you will not have to rely on warranty service.

Connection diagram of storage gas water heater

Here are the main recommendations in connecting the product to all communications that must be strictly followed.

1. The boiler is installed in such a way that there is a gap between the product and the wall necessary for the inspection and maintenance of all components.
2. A pipe of at least ¾ inch is used for the connection, while there is an important feature: the hot water outlet pipe is connected to the left and the cold water inlet to the right.
3. To avoid overheating of the water heater it is necessary to apply safety valve.
4. Before you connect the device to the water supply system, turn on the water and check its quality for impurities. A better install on the supply pipe special filterprotecting expensive equipment.
5. Few users know that the pressure should not exceed eight bar, otherwise a reduction gear should be installed.
6. Water will constantly drip from the hydraulic valve - this is normal, but you need to install a pipe to drain it to the sewage system so that it does not hit the boiler body.
7. If in the winter you constantly do not live in a country house, then at each departure drain the water, otherwise the equipment will become unusable.

As you can see, there are many nuances when installing a water heater on gas, but if you do everything that is required, then the product will work properly for a long time.

Security measures

Often, many users have doubts about the safe use of equipment using an open flame, but manufacturers assure that they have taken all necessary safety measures. These systems include:

• thrust sensor, which is triggered by any violation of the functions of the chimney - it immediately turns off the gas supply;
• hydraulic valve - it instantly reacts to the absence of water, the gas supply is immediately blocked so that the equipment does not overheat;
• flame controller - this is an ordinary thermocouple, sometimes it is supplemented with an ionized corrector, if for some reason the flame is extinguished, the flow of gas is blocked, thereby preventing its unwanted leakage.

Exhaust hood, which is in any product of this class, prevents the possibility of a reverse flow into the room where the boiler is installed, combustion products. Therefore, the user can not worry - all harmful substances are safely removed and the inhabitants of a country house does not face a headache in the morning due to the use of a gas water heater.
