What can be cooked from squid: fast and tasty

Gas storage water heaters necessary in every private house, especially since if there is no boiler room nearby, you can forget about hot water. And it is very necessary, at least for a pleasant stay in the bathroom and a comfortable shower, washing dishes and cleaning the house.

Breadth of application of gas storage water heaters

Therefore, storage gas water heaters are so popular among many customers and are bought primarily for country mansions and cottages. But they are also often used in city apartments in order to save on hot water supply, in office and industrial facilities and in other places.

Find gas water heaters for hot water in online stores it is not always possible, for the reason that their sales volume is not as high as, for example, other types of water heaters. However, on the website of the MirCli online store you can find a fairly large selection of heater models to suit your taste and budget.

The considered devices have many advantages, but still their main advantages are ease of maintenance and operation, cost-effectiveness, which means a constant supply of hot water, and their low price.

These devices are stationary closed type boilers with an atmospheric injection gas burner for liquefied natural gas, as well as ceramic heat removal rods. Water heaters allow you to store a large amount of water, depending on the volume of the tank. It can be different, each model has its own, but usually its dimensions vary from 10 to 200 liters.

Differences and features

There are two types of gas storage boilers: vertical and horizontal, and they differ from each other only in the position of the tank, so you need to choose them according to your bathroom. If this does not matter, it is worth taking a vertical one, since usually with the same characteristics its cost will be lower.

Many of these devices can be connected to several points at once, as their water supply allows this.

Many storage water heaters have their own protective features that will secure their use in the house. So, if the flame in the pilot burner of a gas boiler for heating water suddenly goes out, the gas supply will be automatically turned off. A multifunctional regulator allows you to adjust the pressure in the nozzle, as well as the gas flow in the burner. This regulator is also useful in that it dampens pressure fluctuations in the gas network on the burner.

Storage-type gas water heaters (boilers) are not a very common technique. Meanwhile, they allow the family to provide a constant supply of hot water at minimal prices. Due to the huge difference in the cost of electricity and natural gas, each liter comes out several times cheaper.

A big plus of the boilers discussed in this review is the high rate of water heating. A gas burner with an open flame does its job better than electric heating elements, and at the same time for it there is no concept of overheating. But the drives themselves have it, which give out water with a maximum temperature of + 70-80 ° C, and then go into the "waiting" mode. Most modern models are equipped with thermostats, so you can choose a more comfortable heating.

What is good - almost all storage water heaters are non-volatile, that is, they do not need an outlet. Thanks to this solution, you will definitely not be left without hot water if the light goes out. However, a minimum set of protective devices is present even in the simplest boilers, making their operation safe.

One of the most voluminous household gas models with a 200 l tank - Ariston SGA 200 R. At the same time, the heater power is only 8.65 kW.

Other characteristics of a non-volatile boiler:

• Maximum heating up to +75 °С.
• The consumption of natural (liquefied) gas is 1.07 m3/h (0.785 kg/h).
• The water pressure at the inlet is 8 atm.

Simple Ariston water heaters are quite convenient to manage: an external thermostat is placed on the body, allowing you to select the temperature, as well as a light indicator. Other useful features: auto ignition, flame control, overheating and draft sensors in the chimney.

The inner coating of the tank is enamel, which is good for protecting steel from corrosion, but not very good in terms of the resistance of the coating itself. Also, these boilers often receive negative reviews due to the fact that the gas burner on the igniter is unstable. The most unpleasant thing is that this often happens in winter, when gas consumption increases and pressure drops. The masters call the clogging of the nozzle the cause and advise to clean the burner more often.

Italian gas boilers provide for the possibility of reconfiguring universal burners to supply liquefied gas. You can also choose a relatively compact model or buy a high-capacity floor standing version. In general, the range pleases.

We will give a description of the smallest gas water heater Baxi SAG-3 for 50 liters. This is a wall-mounted option, for which there is a place in the usual urban kitchen. All other characteristics of Baxi crumbs are no worse than those of "adults":

• Power - 3.9 kW.
• Maximum heating - up to +70 ° С.
• Safety valve at the inlet - up to 8 atm.
• Chimney - d = 81 mm.
• Burner - universal stainless steel with piezo ignition.

3 Bradford White.

American gas water heaters Bradford White DS1-40S6BN have a very non-standard design: their tank is covered from the inside with heat-resistant glass ceramics, which completely eliminates leaks due to metal corrosion. Interestingly organized and presentation cold water- it is sent to the container in the form of a turbulent flow, immediately mixing with the heated liquid. Bradford White boilers use an injection gas burner, which is distinguished by its stable operation at any pressure in the fuel line. And the use of a closed-type combustion chamber made the efficiency indicators better.

Technical characteristics of the gas model of the boiler DS1-40S6BN:

• Power - 11.1 kW.
• Volume - 151 liters.
• The maximum temperature is +70 °С.
• Permissible water supply pressure - 10 atm.
• Chimney connection d = 76 mm.

The water heater is designed for floor mounting and has a good set of protective systems: gas control, automatic burner control to maintain set temperature, overheating shutdown. The design also provides for a sensor and a draft stabilizer in the coaxial chimney, plus an overpressure relief valve.

The Germans came up with an unusual design for their Vaillant Atmostor VGH 220/5 XZ gas boilers: here the combustion chamber was inside the drive, more precisely, in a deep recess in its bottom. So the manufacturer managed to nullify the heat loss during fuel combustion.

These gas water heaters are also distinguished by a very thick layer of thermal insulation (5 cm versus the standard 2.5 cm), which allows you to better maintain the temperature of the internal tank. At the same time, the power characteristics of the 220-liter model are very modest - 8.5 kW.

How to choose a heater?

Sometimes we have to state with sadness: the drive is not suitable for you and you need a more compact geyser. Most often, this decision is made by the owners of small apartments, where a bulky tank simply does not fit. However, Ariston has a good option - 50 liter containers. They are attached to the wall, have relatively modest dimensions and differ from the speakers only in their “pot-belliedness”.

It will be more difficult to correlate your idea of ​​comfort with the capabilities of technology. Which is better to choose a water heater, instantaneous or storage - the question is just from this area. In the first case, you will get a stable but moderate pressure of well-heated water. And the extra capacity will provide a strong flow high temperature, but only within its scope. That is, sometimes you will have to wash in the shower with cold water. What is better for you - decide for yourself.

In order not to make a mistake when choosing sizes storage tank, you need to focus on the composition of the family and the number of consumers. Approximate numbers look like this:

1. 30-50 liters - enough for one person to take a shower and there may still be a little left for washing.

2. 50-80 liters is the best option for a couple.

3. 80-100 liters - enough for three points of water intake (kitchen sink, shower and washbasin), which meets the needs of a family with one child.

4. 100-120 liters - this volume is intended for four people.

5. 120-150 l - feel free to add a bath to the main consumers.

If you do not want to overpay for household appliances, you can purchase a boiler with the minimum allowable volume. Gas storage water heaters reach the desired temperature much faster than electric ones, so you won’t have to wait long for the next portion. The presence of a built-in thermometer is welcome - buyers often complain in their reviews that they really lack this elementary thing.

Although such equipment is simple and in most cases is non-volatile, it has one significant drawback - the boiler provides water only at the temperature that you set on it. If this state of affairs does not suit you, you will have to fork out and choose an expensive automated system.

Having decided which boiler will better cope with the tasks, you can go shopping. But first, take a look at some of the technical highlights:

• Container cover.

Each manufacturer has its own favorite set of materials for budget and elite series. You should also focus on durability, because without a reliable coating, gas water heaters will not last long - they will rust and leak. Enamelled tanks are cheaper than stainless steel, but they absolutely do not guarantee a long life for equipment.

• Presence of protective systems.

This is your safety, so do not neglect it. Any, even the simplest boiler, must have gas and draft control in the chimney. A plus is the presence of protection against overheating and switching on when the tank is empty.

• Camera type.

It can be open or closed. The first is cheaper, but it will take oxygen, and in much larger volumes than a flow gas column. These water heaters are installed in separate room where you can bring the chimney to the street.

Closed chambers are a sign of gas water heaters that need additional power from the network. They are noisy, but at the same time more economical. In these models, the burner operates in ideal conditions with the right oxygen concentration. It is good to connect such equipment to a coaxial chimney, then both the air intake and the removal of burnt gases will go through one pipe.

Any storage water heaters need serious thermal insulation of the tank. It allows you to keep water hot longer and not waste resources on constant heating. So there is only one rule in this matter: the thicker the insulating layer, the more economical the boiler.

Reviews

“I didn’t have time to change heaters at the dacha: any gas water heater burned out after a year, the drives lasted a little longer. The reason is the composition of the water in the village. Not only is it tough, it also has iron above any norm. Therefore, I want to give advice: before you buy a water heater, you need to make a normal cleaning system at the inlet.

Sergei Shapovalov, Rostov-on-Don.

"I set myself gas Ariston SGA200 R models. In the second year, problems began: the igniter goes out, it takes a long time and patiently to kindle it. Since this happens only from time to time, I sin on automation. I cleaned the contacts on the thermocouple, but only achieved an improvement in heating. The burner still responds to a decrease in temperature according to mood. ”

Ruslan Mitskevich, Nizhny Novgorod.

“I don’t know – maybe modern boilers have some problems. An old gas Ariston of 80 liters has been working for me for 12 years and it causes almost no trouble. He has one drawback - the thrust sensor failed immediately after installation. Later, in the reviews, I often saw that people with Aristons have the same trouble. It is treated with a simple circuit and the hope that everything will work out.

Alexander, Moscow.

“I have always considered American gas water heaters to be super reliable and justify their cost. The previous one honestly worked for me for 14 years and was sent to the country as obsolete. In my review, I want to warn everyone at once: the fact that the water heater does not cause problems should not relax you. Give it maintenance once a year so you don't miss the moment when the magnesium anode wears out. Otherwise, a hole in the tank is guaranteed.

Maxim, St. Petersburg.

Russian consumers quickly appreciated the quality and functionality of this line of German Bosch speakers, their rating is 5. Household appliances of this trademark reliable, durable and have high-quality functionality. Heat exchangers are made of copper using ultrasonic soldering technology, their service life is at least 15 years. The current information is displayed on the LCD display. Devices have effective system self-diagnosis. The Therm 4000 S range of products are similar in design and differ only in terms of performance, each of them will effectively provide water to a facility with corresponding needs.

Therm 6000S

The limited area of ​​use of the Therm 6000 S industrial water heater was the reason for the reduction of the rating to 4.

Therm 8000S

The Therm 8000 S implements an innovative method for efficient water heating, which gives an efficiency of 100%. Additionally, the device has an electric drive for the water valve. These factors led to the highest user rating - 5.

All water heaters have a similar security system:

The ionization device controls the presence of a flame;
a special sensor controls temperature regime in the chimney, and, if necessary, gives a signal to the shut-off valve;
the heat exchanger heating sensor sends a signal to the control unit when the temperature is exceeded, the control unit performs a blockage;
temperature sensors are installed on the inlet and outlet pipes.

Important! A potential owner of a gas-fired water heater should not skimp on household appliances no security system. Ensuring the safety of the home is the main task, therefore, the more complex the system, the more protection is provided to real estate and household members.

Ariston

The Italian manufacturer supplies the Russian market with only one model of a gas water heater with a closed combustion chamber - Next EVO, but in two versions - SFT 11 NG EXP and SFT 14 NG EXP. This new generation device is designed taking into account the peculiarities of Russian conditions, it will be able to provide efficient water supply, even when the water flow changes. It is highly economical, has an improved design and advanced functionality.

SFT11NG EXP

SFT14NG EXP

This modification differs from the basic productivity and other characteristics, which allows the consumer to choose the best option for specific operating conditions.

Beretta

The Italian concern Beretta produces several gas water heaters with a closed combustion chamber, among which three models are in high demand.

Idrabagno 13 ESI

This technique is rated extremely positively by the owners - 5 points. Whole the lineup water-heating household appliances with a closed chamber of the Beretta brand have the following advantages:

Economical consumption of electricity, which is used only after turning on the tap;
the temperature of the liquid can be adjusted using a mixer;
the equipment is reliable and characterized by exceptionally quiet operation;
reasonable price, the devices are available to a wide consumer audience;
automatic ignition system;
heat exchanger made of high-quality material, burner - modeled;
the ability to work even at low water pressure parameters in the system;
modern system control that guarantees high level security.

The only disadvantage can be called a relatively large size, which is fully offset by a modern elegant design.

Important! Whatever model you choose, the user must understand that only half of the performance and efficiency of equipment depends on its quality, the remaining 50% depends on competent professional installation.

Summarizing

We will summarize all of the above in a table so that the potential owner of a flowing gas water heater with a closed combustion chamber can make a choice that is relevant for a particular object.

For all the models described above, manufacturers have established a guarantee of 24 months. During this period, free repairs are carried out in service workshops, which are equally widely represented in Russia by Ariston, Bosch and Beretta.

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

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

The boiler is filled with water automatically. When cold water enters the tank, the gas supply to the burner is turned on, the resulting heat flow exits 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 turns off the gas and the heating stops.

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

You can learn visual information about the device of a gas boiler from this video:

Types of boilers

Experts classify such household appliances according to several criteria:

1. Combustion chamber type - open or closed.
2. Ignition system - from a piezoelectric element or an electrical home network.
3. According to the method of installation - on the floor or wall-mounted.

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

The cost of this type of water heater is cheaper, but the arrangement of the chimney system will cost a pretty penny, which does not appeal to users.

With closed combustion chamber

A boiler using forced draft is considered by experts to be a more economical option for placement in your home: its closed chamber has a special system for removing combustion products using powerful pump. This species 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 their homeowners choose private buildings.

With piezo element

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

Some homeowners are looking to purchase the latest gas boiler with latest system auto start, which works independently - you just have to open the tap. Similar models are much more convenient in operation and consume blue fuel very economically, and the piezoelectric element can be powered by electric power or Mars-type batteries.

floor version

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

Wall placement

As a rule, with this option, water heaters have a more compact look: they are placed in the bathroom over a sink or toilet, which allows users to save space and use it more rationally. These water heaters are designed for a small volume, 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 storage type water heater that is ideal for your family, you need to know the consumption of hot water per person. Experts assure that this figure is in the range of 50-70 liters. daily consumption. Manufacturers of similar equipment produce various options with a volume of up to 300 liters, so choosing the right option will not be so difficult.

When a water heater is purchased for a family living in their own house outside the city, then it is necessary to consider options no lower than 150 liters - it is this volume that can satisfy the personal hygiene needs of all household members. For those who doubt the validity of this statement, let's do a little calculation:

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

Now multiply all this 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.

Additional device selection options

When choosing a storage gas boiler, you should pay attention to the following important parameters.

Rated power

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

Production material

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

The first option is much cheaper than the second, but when choosing, the user must also take into account the fact that the first tank has thinner walls, which is of primary importance in the event of frequent water hammer in the water supply system. Stainless steel more resistant to corrosion, and the special enamel coating may crack over time - the container quickly rusts and becomes unusable.

When different coatings are used 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: microcracks appear over time from frequent temperature changes, to prevent their occurrence, the user must set the temperature not exceeding 60 0 C. Sometimes, in order to prevent the development of various bacteria, it is necessary to heat the water almost to a boil.

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

Magnesium anode

All boilers are equipped with such a device, its technical name is electrochemical protection with a sacrificial anode, which is made mainly of magnesium, sometimes zinc. The anode gradually dissolves due to oxidation, providing reliable protection inner surface of the tank against corrosion. The replacement also depends on the structure of the water: it is changed at least once a year for sprayed tanks, 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.

Insert scheme and installation

Mounting gas equipment is strictly regulated, so you can’t do without a specialist with the appropriate approval - otherwise you won’t have to rely on warranty service later.

Scheme of connection of a storage gas water heater

1. The boiler is installed in such a way that there is a gap between the product and the wall, which is necessary for inspection and maintenance of all components.
2. A pipe of at least ¾ inch is used for connection, and there is an important feature: the hot water outlet pipe is connected on the left, and the cold water inlet is connected on the right.
3. To avoid overheating of the water heater, it is necessary to use safety valve.
4. Before connecting the device to the water supply system, turn on the water and check its quality for impurities. And it is better to install on the supply pipe special filter protecting expensive equipment.
5. Few users know that the pressure should not exceed eight bar, otherwise a reduction gear must be installed.
6. Water will constantly drip from the hydraulic valve - this is normal, but you need to install a pipe to drain it into the sewer so that it does not get on the boiler body.
7. If you do not permanently reside in the winter 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 the 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 lack of water, the gas supply is immediately blocked so that there is no overheating of the equipment;
• flame controller- this is an ordinary thermocouple, sometimes it is supplemented with an ionized corrector, if the flame goes out for some reason, then the gas flow is blocked, thereby preventing its unwanted leakage.

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

Residents of private houses connected to the gas pipeline often prefer to use gas not only for heating their homes, but also for heating water. This decision is more than justified, because gas is a fairly cheap fuel. Thus, hot water supply provided with gas equipment is very beneficial for the family budget.

If you decide to heat water in this way, then you have two possible options- gas boiler or gas water heater. The first device is a storage type water heater, and the second is a flow type. Today we will talk about storage gas water heaters: their main characteristics, varieties and features of operation.

Device and principle of operation

Storage water heaters, unlike instantaneous ones, heat water in advance. Heating takes place in a metal tank, which is the main part of the design of any boiler. The size of the tank depends on how much water it is designed for. Domestic boilers with a capacity of 50 to 300 liters are on sale.

The water in the tank is heated by a heat exchanger. Most often it is a steel or brass coil. It is located at the bottom of the tank or distributed over almost the entire surface of the device. The coil receives heat from a gas burner, which is located at the base of the water heater in a special combustion chamber equipped with a flame tube.

In addition to all of the above, the design of the gas boiler contains heat-insulating elements, pipes for supplying and discharging water, as well as a variety of sensors.

The tank is filled with water automatically. When a fresh portion of water enters the tank, the gas burner turns on, the heat from which exits through the flame tube and heats the tank. As soon as the water in the tank heats up to the desired temperature, the sensor is triggered and the gas supply stops.

You can get even more information about gas boilers from the following video.

Kinds

There are several types of storage gas water heaters.

Such devices are classified according to the following criteria:

• combustion chamber type: open/closed;
• type of ignition: piezo ignition / electric ignition;
• installation method: floor / wall.

Below we will take a closer look at each variety of this kind of device.

With open combustion chamber

Open draft gas boilers are equipped with an open combustion chamber. They work according to the following principle: the air necessary for combustion comes directly from the room in which the water heater is installed. Combustion products are discharged through a separate pipe - a chimney, which should be equipped in advance.

This type of gas boiler is cheaper, but the installation of a ventilation system is quite expensive, so from this point of view, the next type of water heater is more economical.

With closed combustion chamber

If you do not have the opportunity to equip a chimney in the house, the only possible way out is to buy a forced draft boiler. Such devices have a closed combustion chamber equipped with a system for removing combustion products. For this, a special pump is used, which draws out the smoke.

For boilers of this type, it is not necessary to purchase additional ventilation, since they do not take oxygen from the room. That is why the owners of private houses usually give preference to them.

With piezo ignition

To ignite modern gas equipment, there is no need to use matches or a lighter. Even the simplest models of gas boilers start heating after a simple push of a button. Water heaters that are not equipped with an automatic heating function belong to the class of devices with piezo ignition. Many consider such devices already obsolete, but they are losing their popularity due to their low cost.

With electric ignition

More modern models storage gas water heaters are equipped with an automatic ignition system that starts independently when the water tap is turned on. Such models are more convenient to operate, moreover, they consume fuel more economically. The electric ignition system is powered by electricity or batteries.

floor standing

Floor-standing gas water heaters have a large volume - from 100 to 300 liters, so they differ in rather big dimensions. This must be taken into account when buying, since finding a place to install such a large device can be quite difficult. Since this type of boiler has a large capacity, they are usually purchased by owners of private houses in which there is no hot water supply all year round.

wall

Wall storage water heaters are more compact. Usually they are placed directly above plumbing fixtures. This is very convenient, as it allows you to more rationally use the space. Devices of this kind are designed for a small amount of water, so most often they are bought for installation in city apartments - as a temporary solution to the problem of lack of hot water during seasonal shutdowns.

Popular volumes

The volume of the tank is the most important factor when choosing a storage gas water heater. Many significant and not very nuances depend on this parameter, ranging from the time of water heating to the dimensions of the device. Manufacturers produce boilers with a capacity of several tens to several hundred liters.

When choosing the right volume of a water tank, you need to take into account the number of households and the daily water consumption for each of them. For example, for families with small children, it is more expedient to buy more spacious models, and for single people or couples who are rarely at home, very small water heaters with a volume of 10 to 50 liters are suitable.

150 liters

If we are talking on the purchase of a storage water heater for a country house in which the family lives permanently, it is necessary to consider devices with a tank volume of at least 150 liters. It is this amount of hot water in the tank that is necessary so that a family of several people does not have problems with hygiene procedures.

200 liters

It is estimated that bathing requires 150 to 200 liters of water, showering 50 to 90 liters, and washing dishes requires 20 to 30 liters of water per day. Add to this 10-15 liters, which are spent on washing and washing hands, then multiply the resulting number by the number of households. The result of the calculations may surprise you unpleasantly. That is why water heaters with a large tank volume (from 200 liters) are considered the best solution for a family, especially if she lives in a private house without hot water supply.

Connection diagram and installation

Installation of the storage water heater should be carried out in strict accordance with the installation instructions, which you will definitely find in the user manual.

• The boiler should be installed against the wall; at the same time, make sure that the pipes for hot and cold water are strictly parallel to it. There should be a small distance between the water heater and the wall, allowing for routine inspection and Maintenance nodal connections.
• It is recommended to use a ¾ inch pipe for connection to the water supply. Stand facing the appliance: the hot water pipe should be located on the left hand, and for the cold - on the right hand.
• Using a safety valve for a storage water heater will help to avoid overheating of the device and the associated unpleasant consequences.
• Before you start connecting the boiler to the water pipes, open the cold water tap. Make sure it is fairly clean, free of sand, rust particles, and other small debris. If necessary, insert a special water filter into the pipe (in the network section up to the water heater).
• Also, before starting installation, it is recommended to check the pressure in water pipes. Its level should not be higher than 8 bar. If this value is exceeded, a pressure reducer must be installed.
• Drops of water falling from the hydraulic valve are a sign of the normal operation of the device and the water supply network. But it is necessary to ensure that water from the valve does not fall on the body of the water heater. To do this, you need to attach a special drain funnel to the valve with an outlet to the sewer.
• If the boiler is installed in a country house that does not have constant heating, you need to make sure that no water remains in the tank when the temperature outside drops below zero. Therefore, when leaving the house in the cold season, always drain the remaining liquid from the tank, otherwise the device may fail.

Ventilation

Accumulative gas water heaters that take air from the room in which they are installed should be placed only in rooms that meet several important requirements:

• air intake is carried out from the street or from adjoining premises;
• the room has a ventilation hole with an area of ​​​​at least 1 m 2 (the area of ​​\u200b\u200bthe hole is calculated depending on the power of the device - 6 cm 2 for each kW);
• the ventilation hole must be covered with a grate that does not impede the movement of air, and the hole must not be cluttered with anything.

It is impossible to give unequivocal advice about which water heater is better: gas or electric, instantaneous or storage. Each of the varieties has its own advantages and disadvantages.

So, gas boilers are more economical, but they are considered less safe than electric ones. Storage water heaters provide uniform heating of water, but flow-through models heat up faster and in large volumes. Therefore, each buyer must decide for himself which of the characteristics of water heaters is more important for him. In addition, the technical possibilities of connection should also be taken into account, such as the presence of a gas or water pipeline with normal pressure in the system.
