Domestic electric boiler and features of the house heating system

 

 High efficiency and efficiency of the electric unit is provided by simplicity of its design. The main element of the simplest heating boiler is a heating element - a tubular electric heater, which is located in a special tank with water (coolant of the heating system).

The principle of operation of Tena actually repeats the principle of operation of an ordinary electric kettle. The only difference is that the water from the heat exchanger tank enters the heating system after heating.

The circulation of water in a closed heating system of the house is provided by the basic physical law, according to which the heated liquid rises. In fact, to create a working heating system, all this is enough.

Further complication of the design of the electric boiler and fouling of its additional components are designed to increase the efficiency of the unit, safety and ease of use. The number of different "frills" of the design depends on the model of the boiler and the reputation of the manufacturer. More expensive units have a large list of different options. And cheap ones offer only the necessary minimum of basic opportunities.

Tenko electric boilers from a domestic manufacturer operating in Ukraine for 10 years offers a choice of dozens of models for all needs, different configurations and prices. Given that the price of heating, gas is always rising, it will be a smart choice, and a profitable investment for your home. Interestingly, in the yard is already 2021, and everyone uses modern smartphones, and where some make smart and autonomous buildings, so electric boilers can, if necessary, have a Wi-Fi module for remote control of the boiler via the Internet, it will conveniently use the boiler and save energy when you are not at home, or turn on when you move home. We also learned that the domestic manufacturer offers the boiler user a 2-year warranty, although the warranty may not be needed, because these boilers use quality components.

As a rule, heating boilers have several heating elements, which allows you to use step-by-step control of operating modes, ie, if necessary, connect only the necessary part of the full power. In addition, such a design will ensure trouble-free operation of the heating system - the house will not freeze, even if one heating element suddenly fails. Only the heating efficiency will decrease.

It should be noted that no boiler, even the cheapest, today does without an electrical part called the control unit and automatic control. It is responsible not only for temperature control (it is necessary to cover only the handle of a temperature regulator or to set these values ​​on the electronic panel), but also for safety of use of the unit. The thermostat will not allow the boiler to overheat the water above the set temperature, and the pressure sensor will not turn on if the water pressure in the system is too low.

There are several options. The advantages of relays and thermostats of the mechanical type include their cheapness, and the disadvantages are the relatively low accuracy of temperature control and excessively loud sound when triggered.

The unit of electronic thermostats and thermostats, despite the high cost, is better. In addition to low noise, its use allows you to more accurately adjust the operating modes and thus reduce energy consumption, sometimes up to 20%.

More solid heating units are a kind of mini-boiler and have an expansion tank inside, a circulating pump and a multifunctional group of automatic control. Such a boiler will take on most of the worries of maintaining optimal modes of operation and management of "weather in the house".

The load relay prevents the boiler from operating during excessive load on the mains. For example, if the washing machine or dishwasher is running. The temperature sensor monitors the temperature of the air in the room, not the temperature of the water in the boiler. There is no need to re-adjust the heating power with each warming or cooling - you only need to set the initial temperature in the house.

The time relay allows you to adjust the operation of the boiler depending on the time of day. This is how the boiler is switched on, mainly at night, when the tariff is lower.

The electric boiler can have two thermal circuits, which allows you to simultaneously heat the house and heat water for domestic use. In this case, both circuits can work independently of each other. After all, heating is not required in summer, and hot water is always needed - a separate DHW circuit will provide this. Although it is possible to organize hot water supply in the house with a single-circuit boiler. For this purpose the special boiler of indirect heating through which heat exchanger water from system of heating circulates is used.

The cost of electric boilers, above all, depends on the manufacturer (imported naturally more expensive), as well as the capacity of the unit. Experience in the operation of electric heaters
