Boilers are gaining more and more popularity, it is becoming more and more difficult for the buyer to make a choice. The storage water heater has storage properties – this is an important quality for saving electricity. Which device is better to choose for a summer residence or an apartment, read in our publication.
The principle of operation and the device of the boiler
Before choosing a model, you need to understand the features of the work. The storage type technique is a metal tank, the volume can be different. From the inside, the walls are covered with enamel, which protects against corrosion. It contains heating elements and magnesium anode. Outside covered with a layer of thermal insulation, the body is made of sheet metal.
Water pipes are connected to it. In the tank, water accumulates and heats up to a predetermined temperature. After that, the heating element is periodically turned on for heating, and thermal insulation minimizes losses.
Scheme of the device of an electric water heater:
There are models that run on gas fuel. The design of the tank is similar to the electric one, but instead of the heating element, there is a heat exchanger inside – a coil made of steel, brass, copper. A coolant circulates in it, which is heated by a gas burner located below. There is an exhaust hood on top, through which combustion products are removed.

Advantages and disadvantages of storage heaters
Advantages of electric boilers:
- A small operating power does not create a load on the wiring.
- Possibility of placement vertically and horizontally.
- Safe and easy operation.
- Devices with dry heating elements not subject to scale.
Of the disadvantages – long heating.
Consider the advantages of gas technology:
- The accumulative will work stably even in case of failures in the gas or plumbing system.
- Simple structure and convenient operation.
- Fast reaching temperature. Gas are able to heat 150 liters in 1 hour. An electric one will take 3 to 4 hours.
Cons:
- High cost and complexity of installation.
- Gas connection is carried out by a specialist.
Features of choice
How to choose the right appliance for your home? The following parameters must be taken into account:
- Capacity.
- heating energy.
- Power.
- TENA design.
- Attachment features.
- Internal coating.
- Functionality.
Since the range is wide, you can choose the right one for the price.
Water heating tank volume
What influences the choice:
- Appointment.
- Number of persons.
- Availability of space in the room.
Decide what you will use the boiler for. If you need to install it in an apartment for permanent use, showering and household needs, choose a volume of 80-100 liters. Since the bathrooms in the apartments are small, the tank will not fit any larger.
For a private house, you can choose 100-120 liters. For a summer house or a kitchen, choose a volume of 30-50 liters – enough for washing dishes. Small models of 10-15 liters can be placed under the sink.
The table will help you calculate the volume consumed:
Heat
If you have gas, you can install a gas water heater. It is more economical and heats up water faster. Please note that you will need to obtain permission to install. Self-assembly is prohibited due to loss of warranty and a fine.
Electrical equipment can be connected with your own hands. Although the water takes longer to reach the desired parameters, thermal insulation maintains heat and ensures minimal energy consumption. Today, electric devices are the most popular.
Power Consumption
It depends on the volume of the tank. The larger it is, the more costly. Standard range: 1 to 3,5 kW. If you have old wiring in your apartment, stop on the device up to 2,5 kW.
TENA design
The usual element is made of copper, inside there is a nichrome thread. This is a submersible type, which is also called “wet”. It is constantly in contact with water, which is why it is exposed to scale. For normal operation, the part needs to be cleaned every six months.
A device with a “dry” TEN is more expensive. This element is a tube that is hidden in a protective case. Since it does not come into contact with water, it lasts much longer.
In the latest models, two parts are installed. They can replace each other or work in pairs.
Pressure and non-pressure type
Free-flow (open) do not depend on the pressure in the system. They are located above the intake point for normal water flow.
Pressure (closed) type are mounted in the water supply system. They provide several sampling points and are equipped with an overpressure protection system.
The principle of placement and fastening
The shape of the body is:
- Round cylindrical.
- Narrow and flat.
Based on placement:
- Wall mounted (vertical, horizontal type).
- The floor.
To make the right choice, start from the area of uXNUMXbuXNUMXbthe room. A flat horizontal container will take up the least space, especially if it is placed under the ceiling.
The larger the volume of the tank, the greater the load it creates on the walls, so when buying a boiler from 200 liters, choose the floor type of installation.
Tank wall coating
This is an important point, because there is always liquid inside. The water heater is exposed to destructive factors:
- Temperature drops.
- High pressure.
- Exposure to impurities, resulting in corrosion and scale.
In addition to the anode, the walls are protected by a layer:
- glassware;
- Enamel
- titanium;
- stainless steel.
Products with a titanium coating receive the greatest guarantee – from 7 to 10 years.
The latest coatings boast a finely dispersed inclusion of silver, which provides hygienic functions.
Management and functionality
Simple models are equipped with mechanical control. The temperature controller is located on the body. The thermostat controls the heating process.
The electronic includes the control unit. Adjustment can be made with keys or touch buttons. The display shows the set parameters. Special sensors control the processes, which are reported to the module.
The electronic type allows you to more accurately configure, save the specified parameters. However, it is more prone to failure than mechanical.
We have considered important aspects of the choice of technique. Let’s take a closer look at the characteristics of individual models.

I am pleased that I bought this water heater, because it has been serving me for 5 years. I turn on the “Turbo” mode and after 15-20 minutes I get a hot stream.
