Features of electric boilers for 380 volts for heating

When compared to models that are connected to the 220 V home network, these units are more powerful. Consequently, rooms that are between 90 and 100 square meters in size can accommodate the installation of the devices. м. Their high power enables them to bear heavy loads.

Nonetheless, some brands have boilers with an indicator indicating 9–12 kW in their assortment lines. They are regarded as universal and are made to work with a 380 V power supply and standard network.

There are single-phase and three-phase models among the units. The value of power is where the differences lie. Devices up to 10 kW are included in the first group, and those over 12 kW are in the second. A network with a voltage of 380 V powers the majority of units.

Features of three-phase boilers

On 380 volts, boilers can operate in single or three phases. For homes larger than 100 square meters, the second choice is thought to be more favorable. The models have a power starting at 10 kW, and the third phase offers some benefits. Along with circuit protection, voltage stability is taken into consideration.

Furthermore, since a step-down station is necessary, there are installation-related limitations.

Advice: Depending heavily on the design, installing a 12 kW 380 volt electric boiler cannot be done without the assistance of a specialist.

Design and principle of operation

Standard heating units come with all the parts they need to operate off of the home power grid.

Among these useful units are:

• network pump;
• heat exchanger;
• expansion tank;
• temperature regulator;
• safety system;
• one or several thermocouples.

The coolant is heated using the latter. Water circulation in the heating circuit is provided by the pump.

An expansion tank is a type of buffer tank that absorbs a portion of the main line’s liquid, which expands as the temperature rises.

When the boiler pressure reaches critical levels, the safety system’s safety valve releases the pressure. The electronic automatic control unit ensures that the device operates dependably.

Types of electric boilers

There are three categories into which all of the available equipment for heating a private home falls. Every kind of gadget has unique features.

heating elements

The most secure devices. An electric heater in the form of a tubular speciality raises the temperature. The element heats up and transfers heat to the water when the voltage is applied. Different devices have different powers; some even have value regulators.

These boilers are unique in that they have rods for pre-treating the water. These units are available from manufacturers as single- or double-circuit models; in the latter, the appliance serves as a source of hot water and room heating.

Benefits of TEN boilers include:

• high efficiency, safety;
• quietness;
• process automation.

The units heat up quickly, operate steadily, and are easy to use.

electrode

Function as a result of the coolant’s interaction with the current. Use of specifically prepared water with salts added is necessary for this design.

Two electrodes are inserted into a tube located inside the boiler. Ions start to move, polarity shifts, and a potential difference happens when the device is in operation. The heat carrier rapidly becomes heated. Strong convection currents raise the water volume’s temperature index. A circulation pump is not used in this process.

Electrode boilers are distinguished by their compact size and straightforward construction. The grounding must be arranged correctly when installing them.

Induction

A metal core with a coil wound on it is inserted into a pipe that is located inside the boiler. Eddy currents are created when this element receives voltage, which heats the vessel that the water flows through. Heat is transferred to the fluid, but in order to keep the coil and core from overheating, circulation needs to be maintained continuously. The highest efficiency rate is up to 98% for induction boilers. There is almost no formation of limescale in such units.

The features of the house itself play a major role in the equipment selection. For instance, circulation pumps are not necessary for electrode and induction boilers, but they are necessary for the creation of an effective heating system in two-story buildings.

Rules of installation

It is best to leave device installation to an expert. The safety of the heating system’s operation depends on accurately calculating the power cable’s cross-section, so accuracy is extremely important.

High power is a defining characteristic of electric boilers operating at 380 V, and the wire needs to be strong enough to support the associated loads. There is also a general formula that states that a current strength of no more than 8 A is needed for every square kilowatt-mm of cable cross-section. When rounding numbers, always err on the side of caution.

The boiler’s connection to the heating system complies with the regulations currently in place for energy-dependent units. The circulation pump is mounted on the return pipe, and plastic components and dielectric parts are used for connections.

Installation and connection diagram

In the event of a short circuit or an abrupt spike in voltage, you can deactivate the unit thanks to the circuit breakers that safeguard the network. It is advised to install an uninterruptible power supply unit in the device’s connection circuit to remove power supply fluctuations.

It is essential to install grounding correctly when installing three-phase equipment for space heating installations. Every task is completed in compliance with the guidelines created by the boiler’s manufacturer.

The wire connection is the component of the connection that requires the most care. The instruction manual outlines the sequence in which to complete this process.

Appropriate plumbing is a guarantee of the boiler operating normally. The return must receive water supply for the appliance. This is done so that liquid can be added while the machinery is operating without causing cavitation to form.

In the supply line, a tap is installed, and in the discharge line, a filter is installed. Additionally, the living room’s heating system’s pipes have valves cut into them.

The lowest point of the heating mains is where the boiler installation must be done. It is necessary to connect a two-circuit unit so that the water in the small circuit is heated to the proper temperature before being fed into the larger circuit.

Operating instructions

Because every manufacturer has a different set of technical solutions, you must become familiar with the instructions before using the device. There are some broad guidelines, though. For instance, it’s important to inspect the equipment to make sure there isn’t any mechanical damage before turning on each appliance. Leaks in the coolant must be prevented.

Monitoring the state of the electrical system is crucial. In order to fix the issue, it is required to de-energize the equipment and contact a master if it turns out that the ground is damaged.

Work that involves installation and repair should be done by specialists. This is because of safety regulations and is regarded as a requirement for warranty servicing.

The model’s features may dictate that the boiler needs to be flushed on a regular basis. It is necessary to keep an eye on the appliance’s operating temperature.

Selection criteria

The primary boiler parameters that need to be considered during the purchasing process are the unit’s thermal capacity and the heating element’s operating principle. The specifications of the home power supply should also be considered.

Rules of installation and operation of electric boilers

We will now examine these regulations in greater detail. There are certain guidelines that must be followed when connecting the electric boiler.

Electrical connection

It is essential to accurately calculate the power cable’s cross-section before connecting the electric boiler. This parameter determines the overall safety of the heating system.

It is important to remember that 380 volt electric boilers are highly powerful, so the cable needs to be matched. There should be no more than 8 A of current per 1 mm2 of the cable cross-section, according to a formula used to calculate the wire cross-section.

Using this formula, you would need to calculate 10000/380/8 in order to connect a 10 kW heating unit to a 380 volt voltage. The outcome indicates that each cable’s current-carrying conductor needs to have a minimum cross-section of 3.3 mm.

A helpful hint is to only round fractional values upwards when choosing the cable cross-section!

Connection to the heating system

A common plan is used to connect all of the electric boilers to the heating system:

• For connection, plastic pipes or jumpers made of dielectric material are used.
