The catalog provides the main parameters for the base model Protherm electric heating boiler:
Advantages of Protherm electric boilers
Unlike gas, solid fuel and diesel boilers, heating boilers do not emit any harmful products, they do not need a chimney and various additional devices.
According to its properties, the Protherm electric boiler is absolutely harmless to environment, and does not require constant monitoring during operation.
Thus, the Protherm Skat 9k electric boiler, like other models in the company’s line of electric boilers, is fully automated; an LCD display is installed on the front surface of the body, which reflects the set readings. The package includes detailed instructions to the electric boiler Proterm Skat 9, where all actions are indicated to achieve coordinated operation of the unit.
The owner just needs to set desired temperature, and in the future it will be supported by automation, with high accuracy up to one degree. After reaching comfortable temperature the thermostat will send a signal to the boiler control unit, which will turn off the power supply. Electric boilers are safe, because the automation monitors not only the temperature of the coolant, but also its pressure. To prevent sudden voltage surges, the boiler reaches maximum mode in stages. A double-circuit electric boiler Skat of any model, in addition to heating, heats water for the hot water supply system (DHW).
Electrical heating boilers extremely compact and fits perfectly into any interior. Wall-mounted electric boilers Proterm Skat can heat areas from 60 to 280 m2 and are perfect for heating apartments, country houses, cottages and offices. Especially good feedback for an electric boiler Proterm Skat 6 kW, which can provide a small office with heat and hot water. There is an example when the owner installed a remote tank, the water in which is heated at night, since the night tariff is valid in the region, and during the day it releases heat into the room.
Installation and connection of electric boilers
The installation and installation instructions for the unit included in the delivery package for Protherm electric boilers contain a warning that in the event of mechanical damage to the casing or damage to the integrity of the components and blocks of the boiler, the warranty becomes invalid. Therefore, when self-installation you need to work carefully and strictly follow the recommendations. In order for the Proterm wall-mounted double-circuit electric boiler to function correctly, it must be connected in accordance with the requirements of the instructions.
Connection to the electrical network of the Proterm 6 kW boiler
The boiler with a nominal power of 6 kW is available in two options for connecting heating elements for 220 V and 380 V. Boilers and heating elements are no different, and the 380 V boiler version can easily be converted into a 220 V version. To do this, it is enough to change the switching scheme. If the boiler is connected to a three-phase network, then 2 kW heating elements in each phase consume a current of about 10 A, since the line voltage is 220 V. Therefore, wiring of 1.5 square meters and a three-phase 10 A circuit breaker will ensure normal operation.
With a single-phase network, everything is somewhat more complicated. The boiler has 6 heating elements installed and with a maximum power of 6 kW, the current consumption will be slightly more than 27 A, therefore, you will already need a wire with a cross-section of at least 6 squares and a 30 A circuit breaker. All of the above applies to any electric heating boiler for the home, of any power , only the current consumption values and the required wire cross-section will depend on the power.
According to the tables for selecting the cross-section of a copper wire, a current of 1 A requires a cross-section of 0.17 mm2. The current in the circuit is determined by the well-known formula - I = P/U, in which:
The first thing you need to pay attention to Special attention- This correct selection cross-section of the electrical power cable. After all, for example, an electric boiler Proterm Skat 24 with a rated power of 24 kW, when connected to a three-phase network, will consume a current of about 30 A for each phase. It is not advisable to connect such a powerful boiler to a single-phase network, because in this case the current at maximum power will increase to 100 A. An electric boiler must be connected only through an RCD.
As for the installation location, the requirements for installing electric boilers are not as stringent as for gas or solid fuel units. And the price of an electric boiler for heating a home is much lower than the prices of other types of boilers.
You can install an electric boiler anywhere, but this place should provide easy access for adjusting the unit or quickly shutting it down if necessary.
If the circuit diagram contains several electric boilers, they are connected in parallel. According to electrical safety regulations, an electric heating device must be grounded.
How to choose an electric boiler for heating your home
