What are electric energy -saving heating boilers

What is it for and how they are used

It is wise to select a gas boiler right away if connecting to the gas line is feasible. On the other hand, electric boilers can be used as supplementary heating equipment, for example, in addition to solid or liquid fuel, or as the primary heating equipment. Next, the most basic low-power boilers are utilized, having a 3–6 kW thermal capacity. A house up to 100–120 m 2 can have heat maintained in it for a couple of days with this kind of power.

The most basic low-power models cost between 11,000 and 13,000 rubles.

First and foremost, a private home up to 100 m 2 can justify the use of even the most affordable electric boiler. When owners are only visiting for a weekend or vacation, the best and most efficient solution is to temporarily heat a country home.

Electric boilers are incredibly inexpensive when compared to other types; they can be installed easily (no chimney or ventilation is needed), and they don’t require special care or attention. The low initial cost of the electric boiler will cover the cost of the electricity consumed with such irregular use for a very long time. The coolant becomes nearly independent if it separates from the heating system.

Device and principle of operation

Unlike other species, electric boilers have a fairly simple device. The coolant is heated in accordance with the correct principle by a heating element (heating element, electrodes, or induction coil) that is installed in the steel case. Coolant circulation can occur naturally or through the use of a circulation pump.

For each type, take a closer look at the working principle and the effect on electricity consumption.

1. Tennovy (rheostat) electric boilers. Modern models use steel heater (tubular electric heaters), most often in pairs for greater power and heating speed. The heating electric boats are more powerful, have the usual square case with a wall mount, which contains other elements of the heating system: circulation pump, a safety valve and a pressure sensor, automation and control panel. They are also equipped with the greatest functionality: modulated power, various work modes, planning for a week, the ability to connect a room thermostat. However, the serious disadvantages of the heating electric boilers are the formation of scale and their dependence of their efficiency on the stiffness of the water and the thickness of the same scale. They can be called economical only when using extremely pure soft coolant and additional presence of softening filters .
2. Ion (electrode). The electrodes fixed at a certain distance from each other are used as a heating element. A variable current replaces their polarity (50 times per second at a standard frequency of 50 Hz), as a result of which water ions between them are in constant movement, their temperature rises. Electric boilers are increasingly in demand and most economical, scale does not form on the heating elements, which positively affects their durability and stable efficiency. In addition, such boilers are absolutely safe and do not require intervention even after power supply interruption, since heating the fluid between the electrodes begins immediately after the supply of electricity to them.

When choosing an energy-saving electric heater for your home, it"s essential to consider efficiency, safety, and suitability for your space. An efficient electric heater should provide consistent warmth while using the least amount of energy, reducing both your carbon footprint and electricity bills. Key factors to examine include the heater"s wattage, thermostat control, and timer options. A lower wattage often indicates less energy consumption, while programmable thermostats and timers can help you avoid overheating or wasting electricity. Safety features like auto-shutoff and overheat protection are also critical. Ultimately, the right electric heater should fit your room"s size, have reliable safety measures, and offer efficient, adjustable heating to meet your comfort needs without draining your wallet.

How to choose an economical electric boiler

Once the type of electric boiler has been selected, it is important to evaluate all models according to additional efficiency-affecting factors.

Single -phase or three -phase type of power

Models with low power up to 5–6 kW can operate on a single-phase network (220–230 V). It will just not be sufficient for single-phase network models with higher power. This implies that the heating elements will be on for extended periods of time, the coolant will take longer to reach operating temperature, and the automated system’s economical mode of operation will be compromised.

Conversely, for electric boilers that use low power for heating, a single-phase network is sufficient; it makes no sense to modify the wiring in order to provide a three-phase power source.

It is important to keep in mind that installing models larger than 10 kW in capacity necessitates working with energy supervision services.

Automation functionality

A three-stage power switch is required in simpler, less expensive models. As a result, the temperature sensor should smoothly modulate the power in more expensive models. Certain models feature factory-save modes and boiler programming by days and hours, allowing the coolant to be heated to its maximum temperature at night while paying less for electricity.

Additionally, a buffer container that works particularly well with night tariffs will be present. This will permit the use of heat that has accumulated during the night during the day, excluding the boiler during peak and semi-hand tariff periods.

The operating mode with an indoor thermostat is the most cost-effective and cozy. Even the most basic indoor thermostat models have numerous fine settings, and boiler automation is more concerned with the room’s air temperature than it is with the coolant temperature—which is more accurate.

Calculation of the minimum required power

Enough models with a capacity of 3-6 kW are available to use as an auxiliary heat source in houses up to 120-150 m 2 with energy-saving electric boilers. The least amount of power required for an electric boiler that is used continuously must be determined using the house’s heat loss.

Said another way, heat loss for a typical Moscow Region home with two brick walls and ceilings as high as 2.7 meters is 1 kW per hour. A power supply of 10% to 15% is also advised, and for electric shoes with heating elements, 20% to 30%, due to the formation of scale and decrease in efficiency.

For instance, the minimum required power of the electric boiler for a private home with an area of 80 m2 would be 8 kW + 20% = 9.6 or 10 kW.

Methods for determining the boiler’s required power: Individual calculations, formulas, and corrective coefficients

Other selection criteria

1. The presence of a circulation pump. Normal natural circulation of the coolant is not possible in heating contours a length of 30 m or more, so it is necessary to ensure it forcibly. This is done using a circulation pump. Wall models in rectangular steel buildings are already with the pump, for other models it must be purchased separately. In any case, it is important to understand that it additionally consumes 60-150 W per hour, depending on its power.
2. One- or double-circuit. The electricity consumption in double -circuit models is practically no different, since they work on the principle of the DHW priority: as soon as the hot water crane opens, it is heated from the heating circuit (without mixing). Additional power of heating elements for hydraulic intensity is not required.
3. overheat protection. A mandatory and important criterion that ensures the safety of the boiler in case of emergency situations (leakage, automation error, refusal of the circulation pump, etc.D.).

There are a number of important considerations to weigh when selecting an energy-efficient electric heater for your house. The size, quality, and amount of heat output of your space must all be taken into account in order to maintain comfort. The objective is to locate a heater that uses the least amount of energy possible while heating your house effectively, saving you money on electricity costs.

Heat pumps, convection heaters, and radiant heaters are a few of the common varieties of electric heaters that are available. Because they provide direct, concentrated heat, radiant heaters are excellent for smaller spaces or niche applications. Convection heaters create a constant temperature by dispersing heat in an even manner throughout a space. Despite their higher initial cost, heat pumps have the potential to be extremely energy-efficient over time because they can heat and cool your house.

Look for heaters with energy-saving features, such as timers and programmable thermostats, when making your selection. By allowing you to regulate the amount and timing of heat generation, these features help you save energy. You can feel more secure and at ease knowing that heaters with safety features like overheat protection and automatic shut-off provide an additional layer of protection.

Finally, take into account your annual heating requirements. You might require a more powerful heating system if you reside in a region with harsh winters. In milder climates, an inexpensive electric heater could be plenty. You can locate a heater that maintains the temperature of your house while keeping your energy costs reasonable by assessing your needs and looking into energy-saving features.
