Basic installation process of an electric boiler

Installing the unit

Installing your electric boiler in the space is the first task. The easiest procedure is this one. The installation options for the unit are wall or floor mounting. It will undoubtedly need a special stand if it is to be installed on the floor.

You’ll need specific anchors if you plan to install the electric boiler on a wall. To begin with, you must mark the wall. Keep in mind that the holes you make on the wall must all be evenly spaced. Drill holes and insert the anchors after that. You can hang the boiler once the anchor has been firmly inserted into the wall.

Wiring

Electric boilers frequently have large capacities. It is therefore preferable to install them rather than using the outlet. It is recommended that the electric boiler and oven be connected straight from the power grid. Making a new, distinct line that leads to the boiler is required in order to accomplish this in the junction box that is installed in the home. The wiring will be dependable shielded from mechanical damage if the cable is laid in a covert manner.

Your boiler can even be connected to a single-phase network if it has a small capacity. In older homes, this wiring is quite common. A basic outlet will suffice if the boiler’s output is 3.5 kW. Installing low-power boilers in apartments is ideal.

Installing safety equipment for the boiler

Installing safety gear is another step in connecting the electric boiler. The gadget needs to be secured once all the wires have been connected. Installing RCDs and circuit breakers in a safety box is required. Your device will be dependable protected from overloads and short circuits by these devices.

Connecting an electric boiler to electricity | Calculating the wiring

To properly connect any type of electric boiler to the power source. It is essential to understand when to apply certain fundamental, frequently used connection schemes and rules.

As an illustration of a connection, consider a three-phase, 380 V electric boiler that will be installed in the 120 square meter (sq. m) home’s heating system.

Let’s begin at the beginning, discussing the option of heating the house with an electric boiler.

CHOOSING AN ELECTRIC BOILER FOR YOUR HOME

Numerous factors must be taken into account when selecting an electric boiler for home heating. This includes the type and thickness of the walls, the area covered by the windows, the local wintertime temperature outside, the height of the ceilings, and a host of other elements.

Such computations are frequently left to experts, who create a home heating project that considers all essential system characteristics, such as the kind and power of the electric boiler. Frequently, a particular model—or several—is even provided for selection.

It is customary to apply the following formula when determining the electric boiler’s power requirements for heating on your own: 10kW.м. of house requires 1 kW of power to heat.

The rule only applies to single-circuit boilers that are used for space heating. If there are two contours and one of them is used to heat water for the hot water supply system, the calculation needs to be adjusted. This also needs to be done at ceiling heights higher than the typical 2,5-2,7 meters, among other situations.

Thus, the house area in our example is 120 sq. м. As a result, we have decided on a 12 kW electric boiler, model ZOTA – 12 series "Econom."

Let’s check to see if this boiler will fit the house’s authorized (allocated) capacity after all the theoretical calculations. Our three-phase input is 15kW, so the 12kW boiler capacity is appropriate for us.

Naturally, only 3kW of the allotted power will remain for the other users in the house if the electric boiler operates at its peak efficiency. This is a relatively small amount. However, such a decision was deemed acceptable because the boiler will serve as a backup boiler and will only be turned on in the event that the primary gas boiler breaks down.

WIRING FOR ELECTRIC BOILER

We now complete the boiler’s wiring after determining the boiler’s power requirements and choosing a particular model to heat the home.

In order to do this, let’s use the information from the article "Diagram of connecting an electric boiler to the power grid," which provides recommendations on the selection of the automatic protection circuit breaker and cable cross-section as well as a detailed explanation of all the fundamental wiring schemes for connecting any electric boiler to electricity.

The documentation for our three-phase boiler, model number "ZOTA-12," reflects that it is intended to operate in a network with a 380 V voltage. It also subtly conveys the boiler’s power consumption, since boilers operating at 220 V are uncommonly capable of producing more than 8kW.

You can also view the quantity of TENS (Tubular Electric Heaters) that have been installed as well as their connection layout. Normally, 380 V systems have at least three boilers installed.

There are at least two possible configurations for linking the boiler to a three-phase network. When the heaters are connected to a "star" and made for 220 V, one is utilized. When the electric boiler’s heating elements are connected in a "delta" configuration and are intended for a voltage of 380 V, another one is utilized.

There are various methods to determine which connection scheme is best for your boiler. The simplest way is to consult the documentation’s scheme, which in the boiler "ZOTA – 12" is situated on the rear of the control panel and appears as follows:

As you can see, the heating elements in this boiler are intended to operate at a voltage of 220 V because it has implemented the "Star" connection scheme. This attests to the fact that the contacts used to connect wires to the heating elements have undergone direct inspection and are ready for star connection. They have jumpers connecting their neutral conductor contacts to their free contacts, which will be connected in alternating phases, each to its own.

As a result, we fit the three-phase electric boiler connection scheme to the 220 V TENS connection, which is labeled "star."

It is still necessary to determine the protective circuit breaker’s nominal value and the required cross-section of the cable for the electric boiler based on power. Examine the table from the article to accomplish this:

Thus, it follows that we will need to install a three-phase electric boiler with a 12kW capacity along the entire 50-meter route. Five-core VVGngLS cable with a conductor cross-section of 4 kv.mm (VVGngLS 5×4kv.mm.) and install a circuit breaker with a 25A differential. or a number of circuit breakers (AB) for 25 amps, designated as C25, and 32 amp protective disconnection devices (RCDs).

You can now install the electric boiler after deciding on it and figuring out the electrical wiring’s parameters and connection scheme. After that, we’ll keep connecting to the electricity.

The following section of the article, "Connection of electric boiler ZOTA to the power grid," goes into detail about how to connect an electric boiler to the grid.

Scheme for connecting the electric boiler to the power grid

The electric boiler that is part of the heating system is frequently the appliance in the house that uses the most energy; in fact, it frequently uses more energy than all of the other electrical appliances put together.

This is not unexpected, as even the unwritten guideline for selecting a boiler for the home indicates that 10 square meters of space need 1 kW of power to be heated. After that, for the purpose of heating a 100 square meter house that is comparatively small (by today’s standards). м. A ten-kilogram electric boiler will be necessary.

Naturally, this guideline is broad; in actual circumstances, numerous considerations are made when determining the boiler’s power; nonetheless, generally speaking, the approximate, average requirements for the boiler rule are accurately reflected.

Thus, for an electricity-hungry device like an electric boiler, whose steady functioning during the winter months is crucial, it’s crucial to ensure proper wiring, choose dependable protective automation, and execute the connection correctly.

You must be aware of the components and operation of the boiler in order to comprehend the connecting principle more fully. We’ll discuss the most popular TEN boilers, which are centered around Tubular Electric Heaters (TEN).

The heating element is heated by the electric current that flows through it. An electronic unit uses a variety of sensors to keep an eye on key boiler operating indicators. Moreover, an electric boiler may have a control panel, circulation pump, etc.

The electric boilers used in households are typically 220 V single-phase or 380 V three-phase models, depending on the amount of power consumed.

There is a straightforward distinction between the two: 220V boilers are rarely more powerful than 8 KW. Due to restrictions on the amount of power allotted to single-phase supply lines in homes, devices with a maximum power of 2–5 kW are most frequently used in heating systems.

As a result, 380V electric boilers have greater strength and are capable of heating large homes efficiently. We will address wiring diagrams, cable selection guidelines, and protective automation for 220V and 380V boilers separately, beginning with single-phase.

Diagram of electric boiler connection to 220 V (single-phase)

As you can see, the differential circuit breaker—which combines the functions of a circuit breaker (AB) and a protective disconnection device—is protected by the boiler supply line for 220 V (RCD). Connecting the grounding to the device body is also required.

Such a boiler’s heating element, or heating elements, if there are multiple of them, are made to run at 220V voltage. The phase and zero connections are made, respectively, to one end of the tubular electric heater.

Three core cables must be installed in order to connect the boiler (Phase, Working zero, Protective zero – ground).

In this case, the scheme of connecting a single-phase boiler to the power grid looks like this: If you are unable to find a suitable differential circuit breaker, or if it is simply too expensive, you can always replace it with a bunch of circuit breakers (AB) + protective disconnection devices (RCD).

The only thing left to do is select the grade and cross-section of the required cable as well as the nominal values of the protective automatics for the proper wiring to the electric boiler.

The decision should be based on the future boiler’s power, and it is best to budget extra for it because you won’t be able to switch to a more powerful, older model of boiler in the future unless you do a major rewiring.

I’ll spare you the pointless calculations and formulas and just provide you with a table that shows the cable selection and protective automation based on the 220 V single-phase electric boiler power. Both methods of connection—through a differential circuit breaker and through a circuit breaker plus RCD combination—will be considered in the table.

The minimum allowable PUE (rules of the device of electrical installations) for use in residential buildings will be specified for the copper cable brand VVGngLS, and calculations will be made for a 50-meter route from the meter to the electric boiler; if this distance is greater, values may need to be adjusted.

Table for choosing cable cross-section and protective automatics based on 220 V electric boiler power

The most important thing is to never take a circuit breaker (RCD) below the appropriate level. RCDs are always chosen one step above the circuit breaker that is paired with them. If you are unable to locate an RCD with the necessary rating, you can use the protection of the next stage. Let’s move on to the three-phase version. Connecting an electric boiler for 220V typically presents no unique challenges or discrepancies.

Step 1	Ensure the electric boiler is turned off and unplugged from the power outlet.
Step 2	Locate a suitable power outlet near the boiler, preferably a dedicated circuit with a 220-volt capacity.
Step 3	If needed, hire a qualified electrician to install a new outlet or upgrade the existing one to support the boiler"s power requirements.
Step 4	Inspect the boiler"s power cord to ensure it is in good condition without any frays or damages.
Step 5	Plug the boiler"s power cord into the designated outlet, ensuring a secure connection.
Step 6	Switch on the circuit breaker for the outlet to supply power to the boiler.
Step 7	Verify that the boiler is receiving power by checking its display or indicator lights.
Step 8	If everything is working correctly, proceed to set the desired temperature and operating mode on the boiler"s control panel.
