What is better to install a gas water heater or water heater. Electric water heaters

To provide the house with hot water, they use centralized water supply, electric heaters, double-circuit boilers and columns. Boiler and boiler are popular among consumers. What's better? Let's try to find the answer to this question together.

Advantages of a gas water heater

Today, home comfort depends on reliable technical equipment. People who decide to save the family budget sooner or later buy a gas water heater for heating water.

This option suits most consumers... Buyers find gas water heaters an economical and reliable option. The column is able to provide warm water to one or more points of water intake in the house, while meeting the needs of all residents. According to new technologies for the manufacture of gas water heaters, enterprises produce efficient devices while maintaining quality characteristics.

Choosing a device for uninterrupted supply of warm water at home, a person takes into account the technical capabilities of a gas and electric water heater. In practice, a gas one is cheaper than an electric water heater. The column can be installed in any type of room with centralized ventilation.

Gas appliances for heating water are divided into flow (columns) and storage (boiler). A significant disadvantage of storage devices is their large dimensions. The gas water heater is much smaller in comparison with the boiler. In addition, in terms of performance, flow-through ones are in no way inferior to storage devices.

The gas water heater is of interest to the consumer, because:

Allows you to save.
Has an aesthetic appearance.
Easy to use.
Has a long service life.
Safe to use.

Boiler advantages

There are many models of storage water heaters on the market. They are divided by price and quality characteristics. Boilers are used in multi-apartment buildings. Exhaust gas during installation is not done.

What are the positive qualities of storage water heaters? Electricity is more affordable than gas... The boiler, in comparison with the column, is capable of performing its functions immediately after connecting to the outlet. An electric water heater runs on electricity without creating excessive pressure in the water supply system. Moreover, hot water will be available in several places.

After heating the water to the required temperature, the boiler automatically turns off to avoid overheating the system. Storage water heaters are very economical in terms of cost, installation and maintenance.

Boilers, in addition to positive qualities, have minor disadvantages. It is more difficult to install a water heater in a room with a small area. The fact is that the size of the unit is large, and the volume of water is insignificant. The liquid heats up over time, not immediately. Accordingly, energy costs increase. The storage water heater must be regularly serviced, which leads to additional additional costs.

Instantaneous and storage water heaters

In addition to gas and electric, there are also flowing and cumulative heaters. Most flow-through units are powered by electricity. In a special flask there is a heating element that heats the water. A flow-through heater of this type is mounted on a mixer.

The water that passes through it heats up very quickly, in a matter of seconds. The water temperature is about thirty degrees. The disadvantage of this type of heater is the high consumption of electricity and excessive load on the power grid. Instantaneous water heaters are single-phase and three-phase.

The storage water heater functions due to the heating of the liquid in a special container. This is the main disadvantage of the unit, since the tank requires a lot of space in the room. It takes several hours for the liquid to heat up. Water retains its temperature for a long time. Thanks to this, accumulative in comparison with flow-through boilers allow you to save a significant part of the family budget.

There are other types of heaters, for example, flow-through storage... In units of this type, water is returned to the system. This boiler is expensive due to its high energy consumption. They are rarely installed in apartment buildings.

In private homes, water heaters are used, which function at the expense of alternative fuels - coal, firewood, and the like. Accordingly, it will not be possible to mount a boiler of this type in high-rise buildings.

There are also water heaters that work through the heating system. The water in these units heats up slowly and to an insignificant temperature.

What to buy

To determine which unit is most suitable, you should carefully study the prices. The parameters of the premises, as well as the needs of the family.

Choose a water heater carefully, considering the technical characteristics of the house... In apartments, experts do not advise installing a flow-through type. Often a fire breaks out due to these water heaters. Better to buy a boiler. Wiring in new buildings is much stronger and problems should not arise.

It is worth remembering that each of the units has its own disadvantages and advantages, which are closely related to the conditions where the device will be used.

Plus a gas water heater - small size... This allows the device to be placed in almost any ventilated room. The column is able to provide the house with hot water in a matter of seconds.

However, for the installation of any type of gas appliance, an appropriate permit must be obtained. To avoid unpleasant consequences in the future, the installation of gas equipment should be carried out according to the rules with the help of qualified specialists.

Before you buy a column, not a boiler, pay attention to the force of the water pressure in the house. This can be done by opening several mixers at the same time, the water supply temperature will change when the column is turned on. This factor does not affect the operation of the boiler.

The column, in contrast to the boiler, works longer and needs minimal maintenance. The system pressure check is performed by specialists once a year. If the water temperature drops and the flow decreases, the heat exchanger is flushed.

Due to frequent interruptions in the supply of hot water, especially in the cold season, residents of apartments and private plots are increasingly thinking about alternative methods of heating water. The most effective of these are appliances such as gas water heaters and electric boilers. Although they perform the same function - they heat water, they still have many differences, such as: different consumption of time for heating water, efficiency in operation, different safety parameters. Before choosing which is better: a gas water heater or a boiler, you need to familiarize yourself in more detail with their differences, advantages and disadvantages.

What is their difference

The main difference between these devices is in the energy due to which they work. The geyser is powered by gas, which is produced by connecting to the central gas pipeline. Such a device was invented a long time ago, and during its existence it has evolved from a bulky unit that requires a lot of space into small compact devices.

The electric boiler has the appearance of a capacious tank with a tubular electric heater inside and a water heating control system outside. There are two types of such devices:

Flowing - a small device that connects to the water supply pipe and heats the water when the tap is turned on.
Accumulative - a tank of different sizes that collects and stores water; heats the water when the tank is turned on.

Unlike a gas water heater, a boiler can work with large volumes of water, therefore, various enterprises often make a choice in its favor.

Advantages and disadvantages of gas water heaters

The main plus of the gas water heater is its efficiency, since gas is currently the most accessible and cheapest type of fuel. Other benefits include:

Long service life.
Ease of use.
Compactness.
Fast heating of water.
No difficulty in repairing.

Gas water heaters are installed mainly in the kitchen, and most of the models are equipped with a thermometer and other useful functions.

A significant disadvantage of the gas water heater is the complexity of its installation. You cannot do this on your own and you still need to additionally purchase the materials necessary for installation, since they are not included in the complete set with the device. Other disadvantages include:

The device runs on gas, it needs ventilation to remove combustion products from the room, which also adds complexity to the mount.
The installation of the device must be coordinated with the gas services.
The temperature to which the column can heat the water depends on the initial temperature of the water in the pipe, which means that if the water is too cold (for example, in winter), then the column will not bring it to a hot state.
Medium level of safety, as gas appliances are always subject to an explosive risk.

Advantages and disadvantages of electric boilers

Electric boilers are more popular with users than gas water heaters, this is due to a number of significant advantages:

ease of installation;
no need to build a ventilation system;
operational safety;
independence from the initial temperature and water pressure;
high rate of efficiency.

The disadvantages primarily include the limited amount of warm water in storage electric boilers. When the hot water in the tank runs out, you need to wait until the water heats up again, depending on the size of the tank - this can take a long time. Among other cons:

high price;
a voluminous boiler does not fit in every house;
the cost of energy supply is much higher than that of gas water heaters;
short service life.

Conclusion

In order not to be mistaken in choosing a water heater, the main question that needs to be answered is for which room it will be used. For the home, both gas water heaters and flow and storage boilers will be equally effective. However, if a water heater is needed for an enterprise that is visited by many people every day, then an electric storage boiler with a large tank volume is best suited.

The article described all the main issues regarding heating devices for water and this information is enough for the buyer to decide which is more profitable: a gas water heater or a boiler.

Unstable hot water supply is a common problem. However, you can successfully protect yourself from the inconvenience that this unpleasant phenomenon causes by installing a gas or electric water heater. The variety of types and models of similar equipment on the market allows you to choose the best option for a particular house. But which is better: a boiler or a gas water heater - an objective answer can be obtained by comparing the features of these types of water heaters.

Modern gas water heaters are very different from the unaesthetic bulky appliances of yesteryear. Now these are devices with attractive design and compact dimensions that easily fit into any interior. There are two types of gas water heaters, differing in the type of ignition:

automatic columns - their work begins from the moment the water tap is opened;
semi-automatic - to start such equipment, it is necessary to light the wick manually.

Turbocharged speakers - another step towards excellence

Columns with a turbine are a relatively new invention that eliminates the dependence of the device on the presence of draft in the chimney. This effect is achieved thanks to the built-in fan (turbine), which provides the required level of circulation of air masses and waste products.

The turbocharged speakers are fully automated, which significantly increases the safety level of this equipment. Special sensors record the following parameters:

the degree of heating of the heat exchanger;
water temperature;
pressure level.

If any indicator exceeds the norm, the equipment is turned off.

The turbocharged speaker models are constantly being improved and supplemented with a variety of options. The most common ones are: thermometer, multi-function display, heating and power indicators.

Despite the differences, the columns work according to the same principle: cold running water enters a special heat exchanger made of copper and is heated there with the help of gas. In order for the equipment to serve for a long time, you should opt only for products of well-known brands.

Advantages and disadvantages of modern gas water heaters

The main advantage of these devices is the ability to instantly heat a large amount of water. And this function does not depend on the size of the devices. This is ideal for a large family that consumes a lot of water every day.

Also, gas units of this sample compare favorably with their electrical "counterparts":

compact size - which allows them to be used even in small rooms;
unlimited volumes of heated water;
high heating rate (about 17 liters per minute);
economy;
rare preventive maintenance (during the year, it is enough to check the pressure level just once, and if the power of the device and the temperature of water heating decrease, rinse the heat exchanger);
long service life.

However, there are some difficulties:

before installing this water heater, you must submit a package of documents to the appropriate authorities to obtain permission to install a gas water heater;
after receiving an official document authorizing the installation of this equipment, it is required to invite specialists for:

gas pipeline connection;
checking and adjusting the ventilation system;
direct installation of the device.

strict requirements for the installation of the device imply the purchase and installation of metal pipes (the column can get very hot, and such high temperatures are unacceptable when using plastic products);
the wall on which the device will be mounted must be treated with a sufficient amount of a substance that ensures its resistance to high temperatures (often a rather thick layer is required);
according to safety requirements, the water heating gas unit must be placed in the kitchen (where the ventilation system is established and the chimney is present). To minimize oxygen burnout in the room, it should be ventilated (and should be done regularly).

Naturally, if there is no gas pipeline in the building, the use of such equipment is impossible. The only acceptable option in such conditions is an electric boiler, the advantages and disadvantages of which we will now consider.

Boiler - purpose and main characteristics

A boiler is a storage device for heating water. In practice, this means that the reservoir of the appliance is filled with water, which is then heated. The boiler consists of a highly insulated water tank, a water heating regulator and a special tubular heater. The set temperature regime is maintained thanks to the heating elements that work automatically. This function, as well as a sufficient level of thermal insulation of the device body, significantly saves energy consumption.

Boilers are both electric and gas-fired. They have certain design differences. For example, electric models are installed directly into the plumbing system. Such devices are available with a stainless (more reliable option) or enamelled tank, the inner part of which is coated to prevent corrosion. Electrical equipment is capable of providing hot water to residential and industrial facilities.

Gas boilers can be divided into 2 categories:

Having an open combustion chamber and working on natural draft. Install such devices only in rooms with a functioning chimney. Often, the range of this category of water heaters is equipped with various options for the safest use.
Forced draft appliances with a closed combustion chamber.

Advantages and disadvantages of storage water heaters

The use of a boiler can be a solution to the acute problem of the lack of hot water in buildings without a gas pipeline. These can be non-gasified areas of the private sector or suburban real estate, where there is water supply and access to electricity. Other obvious advantages of this electrical equipment:

you do not need to collect any documents, because the installation of an electric boiler does not require special permits;
you can even install it on your own, having the necessary knowledge and experience;
plastic pipes are enough for mounting the device;
no strict requirements for installation, because the device works without open fire;
the force of the pressure of water does not affect its temperature regime, as is the case in some models of gas water heaters;
the equipment has the correct shape and modern design, which allows you to optimize the space;
the stores offer a variety of boiler models, equipped with convenient options, the size and color scheme of which can be selected for any type of interior.

Disadvantages of electric and gas storage devices:

impressive dimensions (for a large family it is impractical to buy a small boiler, because the tank capacity will not be able to accommodate the required volume of water);
heating duration - about five hours (for a large tank);
constant care and regular replacement of elements;
mandatory installation in places accessible and convenient for frequent maintenance and cleaning of the device.

It is obvious that each type of equipment has positive aspects and certain disadvantages. Therefore, it is better to decide which is better - a boiler or a gas water heater, based on local conditions and the requirements for the operation of devices. Accurate calculations, expert advice and common sense - all this will help you make the right decision and provide the house with hot water, which is so necessary for a comfortable life for the whole family.

Choosing what is more efficient an indirect heating boiler or a gas water heater take into account several features and differences in the design and operation of water heaters. Important factors influencing the decision are: space occupied, costs of operating and heating water, ease of use and existing restrictions.

The difference between a boiler and a gas water heater

Water heaters differ in the principle of operation, internal structure and thermal efficiency. Below are the main characteristics by which the column differs from the boiler, as well as a brief description of the internal structure of each type of equipment, the pros and cons.

BKN - in its internal structure resembles an electric boiler. Only instead of heating elements, a coil or tank is used as the main heating element, through which the coolant circulates.

BKN is connected to a solid fuel or gas boiler. The heated heat carrier enters the heating element located in the storage tank filled with water for hot water supply. Heat is transferred and hot water is heated.

The advantage of an indirect heater in comparison with a gas water heater is as follows:

low requirements for installation and connection: there is no need to obtain permission from Gorgaz, to make a project and approval;
constant maintenance of hot water and instant supply to the consumer (when using a boiler with recirculation);
stable DHW temperature despite the number of water consumption points and water pressure;
simple internal structure and easy operation.

The boiler has its weak points:

large occupied area;
restrictions in the amount of water supplied to the consumer;
the time required for the initial heating of DHW (on average 30-40 minutes);
high price;
seasonal work, heating occurs only during the heating period of the building (minus does not apply to combined boilers with built-in heating elements and operating at any time of the year).

As practice shows and real consumer reviews, it is better to use BKN to get hot water in your home. An instantaneous gas water heater is best used in apartments.
Columns also have strengths and weaknesses. The water is heated in the following way. A burner is located inside the water heater. A heat exchanger is installed above the burner. When gas is burned, heat is released, which heats the water that is constantly circulating through the coil. The column works only when the water supply tap is open and turns off after it is closed.
Advantages of a flow-through gas water heater over a capacitive boiler:
- cheapness;
- no restrictions on the volume of heated water;
- economical gas consumption;
- compactness.
With the existing advantages, there are certain disadvantages:
- high requirements for the location, technical conditions of the boiler room and the need for approvals and project manufacturing;
- a complex internal structure, breakdowns are periodically observed associated with a malfunction of mechanisms and automation;
- the heating temperature depends on the pressure in the pipeline and the number of simultaneously open taps (the problem is somewhat solved in water heaters with modulation burners).
BKN is a storage water heater, the column is a flow-through one. Each has its own advantages and disadvantages. The actual possibilities of a residential building become decisive in the matter of choice:
- For a private house, it is better to put an indirect heating boiler connected to a solid fuel or gas single-circuit boiler. With the right calculations, there will be more than enough hot water.
- It will not be possible to install BKN in apartments with central heating due to the existing restrictions in the regulatory documents. The only option is to install a gas flow column.
Which is more economical - a boiler or a column
When clarifying this issue, not only the cost of water heaters are taken into account, but also the costs of connection, regular maintenance, as well as costs associated with heating water:
- Equipment price- a gas water heater will cost, depending on the model and manufacturer, from 8,000-40,000 rubles. Basically, instantaneous gas water heaters are in the indicated price category, but there are instances that are cheaper or more expensive.

  The cost of the storage boiler depends on the displacement. A 100 liter water heater can be purchased starting from 15,000-190000 rubles. If a decision is made to install a boiler instead of a gas water heater, the cost of purchasing equipment will double.
  Read also: Which indirect heating boiler to choose for a private house
- Heating costs- gas consumption with an indirect heating boiler or a gas water heater is approximately the same. The costs are directly related to the features of the operation of the heaters. The maximum costs for heating water in the column and BKN arise when reaching operating power.
  In a flow-through heat generator and boiler, the highest gas consumption is observed until the water reaches the required temperature. If the water heater is used exclusively for washing in the shower or taking a bath, then a gas water heater is more economical than a boiler. With frequent washing of hands and dishes and constant short-term switching on, the gas consumption in the flow-through water heater becomes more than in the BKN.
- Connection costs- the process of installing speakers, including the official paperwork and the production of project documentation, costs an impressive amount. If there is no boiler in the house and a water heater is needed only to wash dishes or hands, it is better to choose a cheaper option.
  According to the most conservative estimates, the amount required to connect a flow-through gas water heater can reach 30,000-40,000 rubles.

Many people resort to the need to purchase a device for heating water in the summer months, when the water supply is usually turned off. Also, residents of country houses face this problem, since there is no centralized hot water supply in this case at all.

But which is better than a gas water heater or a water heater? Today we will tell you more about what a water heater is and which one is better to choose for your apartment or house. To do this, first let's get acquainted with the main characteristics and features of different types of devices.

Gas water heater

In apartments and houses, the most popular choice is a gas heater. It is easy to use, durable, safe, practical and extremely reliable. In addition, it allows you to heat water much faster than an electric model.

The work of modern devices is fully automated. The burner is ignited when the appliance is started. At this moment, gas is supplied, and in its absence, the flame is turned off. The main advantage of this type of water heater is its economy, since gas is much cheaper than electricity.

These heating devices can be of two types:

The first option is mainly suitable for large families who need a large amount of water consumption. In such a situation, you can install a tank with a capacity of about 200 liters, which is enough for two adults and three children to shower. For a small family, the best option is a flow heater. When choosing it, power must be taken into account. When using one point of water consumption, 19-20 KW is suitable, and for the simultaneous use of water in two different places - at least 24 KW.

The advantages of a gas water heater are:

Optimum gas consumption for heating;
High efficiency;
Low cost.

The disadvantage of the device is the need for the installation of an exhaust hood during its installation, since during the combustion of gas, harmful vapors and products are formed. They must be brought out on the street in a timely manner.

Electric water heater

An electric heater is an alternative to a gas heater, which is no less functional. Usually it is used in apartments and country houses in which gas is not supplied. Also, it is selected for installation in a bathroom and toilet, where the gas pipe cannot be supplied.

In this case, water heaters are also divided into two types - storage and flow. The first version of the design of the device heats the water in the tank to a certain temperature (usually about 37 degrees), after which it is maintained at a certain level.

When the tap is opened, cold water enters the tank, and when its full volume is exhausted, it takes a long time to heat the next portion. It depends on the type of heating element, the volume of the tank, as well as the thermal insulation coating of the tank walls. To reduce heat loss and save energy, the heater structure must be covered with special heat-retaining materials.

Flow models have a compact design, but their disadvantage is high power and, accordingly, high consumption of electrical energy required for operation. In addition, their installation requires specialized knowledge and experience, and only a professional can handle it.

What to choose?

Do you choose a device for heating water, but do not know which is better - a gas water heater or an electric water heater? For an apartment or house with a gas supply, you should use the first option. It has a low cost, low gas consumption, and is easy to operate. However, the use of a gas water heater is associated with high danger.

The electric model does not require specific installation and maintenance. It is safer, but at the same time leads to significant energy costs. Therefore, it is necessary to choose a device after a careful analysis of all the pros and cons of using each type.

What is better gas water heater or electric water heater?

When the water is turned off and when moving to live in a country house, many are faced with the need to buy a device for heating water. However, not everyone knows what is better for a gas water heater or an electric water heater.

Gas water heater or boiler: which is better?

Devices that provide an apartment or a private house with hot water at any time are very relevant these days. Their choice is quite extensive, and it can be difficult to determine which equipment is more profitable in a particular case. In order to buy the right device, it is important to learn about the advantages and disadvantages of each type of water heater.

Types of equipment for providing hot water

According to the principle of their operation, all heating devices are divided into storage and flow-through. The former take water and heat it up for a certain period of time, while the latter perform heating during use. Both of these types of heaters are also divided, depending on the energy carrier used, into electric and gas.

As a result, the following types of water heating equipment can be named:

Gas flow heater (gas column). The water in such a device heats up while moving along the heat exchanger under the influence of the burner flame.
Electric storage heater (boiler). Water is first drawn into the device, and then it starts to be heated by the built-in heating element.
Gas storage heater.
Electric flow heater.

The most common are the first two types, which in most cases are required to be compared to select a suitable water heating device.

Gas water heater

The working column is capable of providing the house with hot water for an unlimited period of time. As soon as the user opens the tap, he immediately receives warm water until the moment he turns off the tap.
Modern dispensers have electronic control that allows you to control the intensity of combustion, as a result of which changes in the water pressure in the pipes do not affect the final temperature of the water coming from the tap.
The speakers are small in size, so they are often bought for a bathroom or kitchen of a small area.
Modern speakers are highly reliable devices. To ensure the safety of their work, many sensors are provided in the speakers.

Gas water heaters are significantly inferior to boilers in terms of efficiency.
The power of the device may not be enough to provide an even supply of water to two points. For example, if the column is low-power, hot water will be supplied to only one tap. Medium-power devices allow you to supply water to two taps, but the pressure will be uneven.
For its operation, the column requires a chimney and good ventilation of the room.
Many columns do not function well when gas or water pressure changes.
When the combustion chamber is open, the oxygen content in the room decreases.
If the water in the pipes is too cold in winter, the column often cannot cope with its heating.
Due to the poor quality of water, gas water heaters have to be regularly descaled.
Installation of gas-powered equipment is quite troublesome and expensive. It requires the presence of a project and its approval, after which the installation and connection should be dealt with by an organization that has a license for such actions.

Installation of such a heater is quite simple and can be done independently.
The device does not need a chimney to operate, and ventilation is not important.
Changes in the temperature or pressure of the water in the pipes do not in any way affect the functioning of the boiler.
In modern boilers, the heating element does not come into direct contact with water, therefore, scale does not form.

Such equipment is unable to quickly provide a large volume of hot water. The volume of warm water received from one boiler is limited, and when the water runs out, you have to wait several hours until the next portion heats up.
The capacity of the boiler may not be sufficient to provide hot water to the entire family.
The dimensions of the storage electric heaters are quite large. Hanging a boiler over a bathroom or toilet, users often bump their heads into it.

Gas water heater or boiler: which is better?

Which is better - a gas water heater or a boiler as a water heater? Which of them is better, more economical and more profitable for installation in an apartment or a private house - a flow-through or storage water heater?
