Varieties of electric shoes, their advantages and disadvantages

The need for electricity-powered heating boilers spurred the creation of new models that operate fundamentally differently from one another.

Tennovy

The original model of electric boiler. One or more heating elements are used to heat the coolant. Ten is made up of the following components:

• External shell: steel, titanium, alloys based on copper or aluminum;
• Inner heating element – nichrome wire.
• Dielectric (ceramic granules or quartz sand) – separates the spiral from the shell.

After ten to fifteen minutes, the heat carrier reaches its rated power quickly. With the use of circulation pumps, the coolant is forced to flow through the system. The majority of models up to 12 kW are wall-mounted and run off a single-phase home power supply. More powerful equipment needs a three-phase power source and is installed on the floor.

Benefits. There isn’t direct contact between the coolant and ten heating elements. A robust outer shell and a thick layer of dielectric keep them apart from it. By doing this, the chance of a short circuit is reduced. Contemporary models are equipped with a multi-stage security system that guards against coolant leaks and overheating of the equipment.

Defects. Similar to the heater’s boilers, a scale develops and drastically lowers heating efficiency. One can use distilled water or specialized antifreeze to lessen the severity of plaque development.

Electric

The following is the electrode (ionization) boiler’s operating principle. The potential difference is produced by two electrodes that are visible in the ionization chamber. An electrolyte with a high concentration of salt impurities is used in the coolant role. You must connect an electric boiler to the heating system in conjunction with such a coolant. Because of its high resistance, the coolant heats up quickly when an electric current passes through it. The boiler exits for rated power in a matter of minutes. The circulation pump is the only means by which the coolant can be forced to move.

Benefits. With a high level of automation and external sensors, you can regulate the heated room’s air temperature in addition to the coolant’s temperature. Elevated dependability is a primary benefit of ionization boilers. They feature a minimal set of details that essentially never break. The electrical wire environment vanishes and the device just shuts off when there is a coolant leak. Since these boilers are capable of operating at 180V, it is advised that they be installed in locations with erratic electric voltage.

Defects. The coolant is expensive and requires careful preparation, ideally prior to each heating season.

Induction

An induction coil and a metal core make up the construction of induction boilers. There are two layers of windings in an induction coil. The primary winding converts electrical energy into magnetic energy, which in turn causes the secondary winding to heat the steel rod. The coolant receives heat from the core.

Benefits. excellent fire safety, economy, and efficiency. They do not form scale, in contrast to heating boilers, but they also do not place as much demand on the coolant as electrodes do. Actually, any liquid can serve as a coolant, ranging from regular tap water to refined oil derivatives. Since there are no parts of the boiler that are susceptible to mechanical wear, its design is fully developed. The allowed service life could be longer than 25–30 years.

Defects. Expensive cost. substantial weight even in small forms. Installation only on the floor is permitted.

Connecting an electric boiler to your heating system requires attention to a few basic rules to ensure optimal performance and safety. Firstly, it"s crucial to properly size the electric boiler according to the heating demands of your home, factoring in insulation, climate, and desired indoor temperature. Secondly, ensure compatibility between the boiler and your existing heating system components, such as radiators or underfloor heating pipes. Proper wiring and electrical connections are essential, adhering to local building codes and safety standards. Additionally, installing appropriate controls and thermostats enables efficient operation and temperature regulation. Regular maintenance and periodic checks help prevent malfunctions and ensure longevity. By following these fundamental guidelines, you can seamlessly integrate an electric boiler into your heating system, providing reliable warmth and comfort for your home.

General advantages of electric boilers

Whatever kind of electric boiler they choose, they offer the following benefits to the user:

• Affordable cost of equipment;
• Ease of installation;
• There is no need to receive special installation permits;
• There is no need in a separate room, a place for fuel, the arrangement of chimneys and exhaust ventilation;
• No need for boilers for boilers: cleaning chimneys, fuel lining of the furnace chamber, etc.P.

Power calculation

An electric boiler must be carefully chosen before being connected. Determine the heating system’s power in order to accomplish this. The formula w = s × WUD can be used to calculate the power needed for a specific model of electric boiler, where:

• W is the desired power (kW);
• S – the total area of the cottage rooms (m 2)
• WUD – specific power coefficient (kW/m 2). The average indicator that is selected from SNiPs. For the European part of the territory of the Russian Federation, it is a unit, for the southern part of 0.8-0.9, for the Far East 1.1-1.2, for the regions of the Far North to 1.6.

As demonstrated by practice, the following statement on 10 m 2 areas of the house must be valid for 1 kW of the heat source’s power for the majority of Russia’s territory. There is an upward rounding. Typically, the indicator exaggerates the calculated value by 10% to 15%. This is done to prevent the boiler from operating in its highest modes.

Installation requirements

An electric boiler must meet specific requirements for connection, even though installation is straightforward. They typically have to do with the following aspects of the equipment installation to the power supply system:

• The wall on which the electric boiler is installed should be made of non -combustible materials. The bearing capacity should withstand both the weight of the installation itself, and the auxiliary equipment and connections;
• Power supply lines should go to me near water or heating pipelines. In extreme cases, the wire should be protected by a special sleeve or box;
• The operating temperature range in the installation rooms should be +5 ° C … +40 ° C with a relative humidity of not more than 85%;
• It is forbidden to install rooms exposed to high humidity;
• The power supply cable is connected to its own RCD and is additionally equipped with an industrial circuit breaker, in which the distance between the contacts in the open state is 3 mm or more.
