Electric storage water heater

If there is no hot water in the house or centralized hot water supply is being prevented, you can use a domestic water heater. The storage electric water heater allows you to use it everywhere. Many different models are produced, with various shapes, power and capacity.

Varieties of water heaters

There are a number of water heaters that are used in country houses. They can use gas, firewood or other materials as fuel.

Important! Old apartment buildings are most often equipped with gas water heaters. But, on the other hand, they do not turn off hot water there, since there is no connection to hot water supply.

We will talk about more versatile water heaters - electric. They are suitable for almost any apartment or house. A detailed description of the selection criteria, important characteristics, devices you will find in the article"Which water heater is better to buy in a private house?".

The heating method divides all such devices into two types. They are:

• Cumulative;
• Flowing.

Differences:

• Dimensions that the flow unit is much smaller;
• The price that the funded one is often higher;
• Principle of operation.

How is a storage electric heater arranged?

Despite the fact that the device of a flowing electric water heater is quite simple, this device is very reliable and economical.

Important! The saving is that the water is heated gradually, which does not require a lot of power. The usual voltage of 220 V is enough for him.

Basic equipment

In general, a storage electric water heater device consists of:

• Housings
• Tank;
• Thermal insulation layer;
• TENA;
• Magnesium anode;
• Thermostat
• Control unit;
• Security systems;
• Indicator;
• Electric cable.

Principle of operation

For proper operation of the water heater, you should familiarize yourself with the principle of its operation:

• A container is located inside the heater body, for the manufacture of which they usually use corrosion-resistant steel.
• High quality enamel is usually applied to the surface of the outer casing.
• For thermal insulation, located between the tank and the body, polyurethane foam is used.
• To process the inner surface of the container, glass porcelain is used. Such material does not exfoliate, so the water remains clean, which is of considerable importance.
• The location of the tank can be both horizontal and vertical. This is important if you take into account the limited area of ​​the room for the location of the device.
• The heater located inside the tank heats the water.

Important! You need to understand that tanks with different volumes heat up over a different period of time.

Protection device

In addition to the heating element, a magnesium anode is located inside the vessel. It is of great importance for the life of the entire device, since rust does not form thanks to it. The entire surface of the tank is covered with a corrosion-resistant coating, but the existing welds are subject to corrosion.

Important! Periodic anode replacement is required. Depending on the manufacturer, it will serve a different term. Manufacturers do not disclose production secrets.

In addition, the storage water heater is also equipped with a built-in protection system, which includes a non-return valve, a gearbox and a safety valve. Thanks to all of them, the boiler does not freeze and does not overheat, which allows it to work longer:

• With the help of a pressure reducing valve, the pressure in the unit itself is controlled, it is reduced to the required level.
• The purpose of the non-return valve is to allow water to flow in only one direction, to prevent its spontaneous discharge in the event of an unexpected stop in its flow.
• The safety valve opens when the water heats up and a significant increase in pressure occurs. In this case, the excess fluid is drained into the sewer.

Important Nuances

Some trim levels do not have a valve, so a separate purchase of a safety group is required. The materials of which the valve is made are of great importance. They must be of high quality. Installation of this part is not very simple, therefore it is better to entrust it to a professional.

After the safety system is installed, before starting the heater and starting its operation, the equipment starts in test mode and each valve is checked.

Important! In order to ensure that the equipment is safe, a residual current device, which is presented in the form of a small block with buttons and an indicator lamp, must be installed on the electric cable.

Operating Rules:

• When using a storage water heater, you can choose the mode of operation that will be most convenient. When using hot water periodically, it makes sense to periodically turn off the appliance. If water is used constantly, there is no point in constantly turning the boiler on and off.

Important! If the container stands without water for a long time, there is a greater chance that it will become covered with rust inside.

• The air temperature in the room should not be lower than five degrees. That is, a water heater cannot be left for the winter in the country.
• When installing the device, grounding is required. This way you can protect yourself from an accident.
• The device can only be connected to the network with a tank filled with water. Otherwise, you can immediately lose it.
• In order to prevent fungi and bacteria from multiplying in the liquid, it is recommended that the temperature be set at least 55 degrees.

Important! Still decide whether to install the equipment yourself or entrust this work to specialists? Step-by-step instructions on our portal will help you understand the process features.“How to connect a storage water heater?”.
