Choose an electric boiler for heating a private house with an area of 100 square meters

Selecting the ideal heating system for your house is an important choice that affects both energy efficiency and comfort. Electric boilers are becoming more and more common for heating private homes because of their effectiveness, simplicity of installation, and environmental friendliness. In this guide, we’ll examine the pros and cons of using an electric boiler to heat a 100-square-meter home while taking energy efficiency, cost, and size into account.

In order to heat your house, electric boilers heat water by means of electrical resistance. The heated water is then circulated through pipes to radiators or underfloor heating systems. Electric boilers can be installed more easily in various parts of your home since they don’t need a flue or chimney, unlike gas or oil boilers. This adaptability can be especially helpful for properties with limited space, such as smaller homes.

The size and output capacity of the electric boiler are important factors to take into account when selecting one for a 100-square-meter home. The amount of heat your home needs depends on its size and insulation levels, so choosing a boiler with the right kW rating is crucial to guaranteeing enough heating power. While undersized boilers might find it difficult to heat your home sufficiently, particularly in the winter, oversized boilers can result in wasteful energy use and increased operating expenses.

When making an investment in an electric boiler for your house, cost is yet another crucial consideration. Although the initial costs of electric boilers are usually lower than those of gas or oil boilers, it’s important to take into account ongoing operating costs, such as maintenance and electricity consumption. However, because they don’t rely on combustion and have fewer moving parts than traditional boilers, electric boilers typically require less maintenance.

For homeowners who want to lower their energy costs and carbon footprint, energy efficiency is a major concern. Due to their high efficiency, almost all of the energy used by electric boilers is converted into heat for your house. Furthermore, compared to systems that rely on fossil fuels, electric boilers can be regarded as a cleaner heating option because they don’t emit any emissions while operating. It is imperative to take into account the source of your electricity, though, as the environmental effects can differ based on whether it originates from non-renewable or renewable sources.

Criteria Recommendation
Capacity Look for a boiler with a capacity suitable for heating a 100 square meter house. Aim for around 10-12 kW.
Energy Efficiency Choose a boiler with a high energy efficiency rating (usually labeled with an A or higher) to save on electricity bills.
Size and Installation Consider the physical size of the boiler and ensure it fits in your designated space. Opt for a model that"s easy to install.
Features Look for additional features like programmable settings, temperature controls, and safety mechanisms.

When selecting an electric boiler to heat a 100-square-meter private house, several key factors come into play. First and foremost, consider the boiler"s heating capacity, ensuring it matches the size of your home. Efficiency is crucial, as it impacts both energy consumption and running costs. Opt for a model with high energy efficiency ratings to keep bills manageable. Additionally, prioritize reliability and durability, choosing a reputable brand known for long-lasting performance. Take into account installation requirements and available space, as well as any specific features or functionalities you desire, such as programmable settings or remote control capabilities. Finally, factor in maintenance needs and potential future repairs, aiming for a model with accessible parts and straightforward servicing. By carefully considering these aspects, you can confidently select the right electric boiler to efficiently and effectively heat your home.

Purpose options for heating

The type of electric boiler to choose will depend on the future uses that are planned. It can serve as the primary source of heating or be used in addition to other sources (like solid fuel); it can be used to keep a room at a constant, comfortable temperature or to heat the entire space when the owners are temporarily visiting.

The most advantageous choice is to temporarily use an electric boiler, as in the case of owners who visit only on weekends. Then, going with a less expensive model makes sense. Even high-temporal electricity costs will be 1.5–3 times less than the starting value for gas, solid fuel, or liquid fuel boilers.

For this purpose, having a GSM module that enables you to operate the boiler remotely over the phone is ideal. This way, you can warm the house to a perfect temperature even before you arrive, or you can ensure that the heating system keeps the temperature at a comfortable level while you are away (if not, you can do it yourself). There will be an instant notification.

It is also justified to employ a low-power electric boiler as backup heating equipment, as shown in the diagram by employing a buffer container in the event that the main boiler unit is unable to function. For this kind of use, a cheap electric boiler that runs on a single-phase network and has a capacity of three to six kW. In a roughly 100 square meter home, he can keep the temperature above +17–18 °C for two to three days.

The use of an electric boiler as the primary source of heating for a permanent home is the most unjustifiable from an economic perspective. However, you can take into consideration the most affordable models of electric shoes if there is no way to connect to the gas line, as well as if you would like to make extra efforts to provide fuel (liquid and solid fuel models), support combustion continuously, arrange the chimney, and provide ventilation.

However, since the actual cost of using an electric boiler to heat a house with an area of 100 m 2 is approximately 10–13 thousand RUB per month, it is worthwhile to calculate the budget for earlier. Furthermore, it is advisable to purchase a generator in case of a temporary power outage, which is common in domestic settings, and to connect the boiler unit through the voltage stabilizer.

The minimum necessary power of the electric boiler for heating a house with an area of 100 m 2

Simplified, the rule determines the minimum required power as follows: for every 10 m^2 of area, 1 kW of heating equipment power is needed for an average suburban home with two bricks of masonry and ceilings as high as 2.7 m. Additionally, it is advised to lay out 15–25% of the power reserve, or up to 30% of the power reserve for tennium models when using hard, non-film coolant.

For instance, a 100 m 2 home requires an electric boiler with a minimum power requirement of 10 kW * 1.2 = 12 kW.

This approach is sufficient for over 95% of homes. Other times, the southern or northern climatic belt, high ceilings, and a large glazing area are taken into consideration when calculating corrective coefficients. Using the calculator below, you can precisely determine the minimum power under such particular circumstances.

Calculator for accurate calculations

The boiler’s power should be sufficient to power every radiator, with each room’s power being determined independently based on heat loss. Thus, in order to get precise data, use a calculator to determine the least amount of power required for each heated room independently, then dry all the values you get to get the result for the entire house.

We determine the type of electric boiler


The most popular kind of electric boilers comes in a wide range of price points, from 1,500 rubles for basic, compact models to 60,000 rubles. High degree of safety, economical, multifunctional automation, circulation pump, and expansion tank are features of highly efficient models.

When a high power is required, the heating element utilizes both itself and the tubular electric heater. A circulation pump, a safety valve, an air carrier, a manometer and a pressure sensor, automation, and an educational control panel are all included in the compact housing of Tennaya boilers in the middle price range and higher. Good tennium electric boilers that have been automated can offer the most cost-effective heating mode while preserving prior comfort.

In particular, it is important to consider the option of using an indoor thermostat to control the boiler. This method is more accurate and cost-effective as it adjusts the power based on the room’s temperature rather than the coolant’s temperature (simple indoor thermostats cost approximately 1000 rubles). The ability to schedule automation for the following day or a week is another fantastic feature.

How to select an external thermostat for an electric boiler to achieve monthly heating savings of up to 30%

The accumulation of scale on the majority of the heating element in electric boilers is a well-known disadvantage that eventually lowers efficiency to 90, 80, or even 70% of the initial 99%. Consequently, more electricity and time will be needed to heat the coolant to the previous temperature through the thick layer of scale. However, the solution to the problem is to use soft filtered water, which is constant throughout the year; it will only react with Ten and produce a thin layer of scale that essentially has no effect on heating efficiency.

The cost of the heating elements is minimal in extreme circumstances, and you can replace them on your own. In actuality, Tena electric boilers almost never experience component failure within the first ten years of operation.

However, it is desirable to connect via a stabilizer, since automation is vulnerable to voltage drops. 40 900-43 800

Electrode (ionic)

Electrodes spaced a specific distance apart serve as the heating element in ionic type electric boats. Their polarity is switched to a high frequency and a variable current, which causes water ions to migrate from one to the other and raise their temperature. The electrode is positioned in the middle of basic low-power models, with the boiler’s coat serving as the second electrode. The more intricate one makes use of two, three, or more central electrodes.

The most cost-effective boilers are electric ones, albeit not by much, as they do not require the buildup of scale and maintain their efficiency over multiple heating seasons. Their sizes differ in a unique way because some models only marginally go over the pipe’s diameter. Almost all ion electric boards require the purchase of every heating system component (expansion tank, security group, circulation pump, etc.D.).

An induction coil serves as the heating component in the induction electric shoes. A magnetic field is produced when the voltage is applied, and vortex currents within the ferromagnetic core—a metal pipe—affect it. The heat from the coolant passing through it causes the core to heat up.

Compared to other types of electric shoes, induction electric boilers are 1.5–2 times more expensive and offer inconvenient advantages for domestic needs. In addition to using water as a coolant, the induction method of heating the coolant allows you to raise the temperature to the desired values 1.5–2 times faster. These advantages are frequently crucial in specific industrial spheres but are rarely justified in homes.

As a result, induction boilers can be used to heat private homes. However, in very rare circumstances, coolants such as antifreeze—which does not freeze at below-freezing temperatures—must be used. This lets you turn off the heating entirely while the owners are away.

Is it reasonable to use induction electric boilers in a private home’s heating system?

There is just one induction model that is currently the most popular and efficient:

Calculation of electricity consumption

All contemporary electric boilers have an efficiency of 99%. For instance, a boiler producing 12 kW of thermal energy at maximum load will use 12.1 kW of electricity per hour. Furthermore, if a circulation pump is available, 60–150 W uses it.

It is crucial to realize that the electric boiler does not always operate at maximum efficiency because the mode of operation is determined by the predetermined parameters as well as the amount of heat loss in the house, which is particularly high during the coldest decades of the heating season. These are specific guidelines that should be planned for in advance. However, during the heating season, on average, more than 40–70% of the maximum power.

For instance, the electricity consumption of a 100 m 2 summer cottage in the Moscow region is 12 kW * 0.5 * 24 = 144 kW/day or 4,320 kW/month, which translates to 5.38 rubles with an actual tariff for 1 kW.h = 23 241.6 rubles/month.

Installing a meter that separates consumption into three zones of the day—peak (7.00 r.), semi-hand (5.38 r.), and night (2.29 r.)—is essential for a noticeable cost savings. Therefore, in actuality, expenses could be lowered to 10,000–14,000 rubles per month.

Selecting the ideal heating system for your house is essential for both efficiency and comfort. An electric boiler is a well-liked solution that is worthwhile to take into consideration for heating a private residence up to 100 square meters. Electric boilers have a number of advantages, such as simple installation, silent operation, and accurate temperature control.

The ease of use of electric boilers is one of their main benefits. Electric boilers don’t need a flue or chimney for ventilation, unlike conventional gas or oil boilers, which simplifies and expands installation options. This means that they can be installed to save valuable space in a variety of places around the house, including utility rooms and even under stairs.

Electric boilers are also renowned for operating quietly. Your home will be peaceful because there are no loud fans or burners because there is no combustion process involved. This is especially advantageous for homes with elderly or young children where noise levels must be kept to a minimum.

The ability to precisely control temperature is another benefit of electric boilers. With the sophisticated thermostats and controls that come with modern electric boilers, you can easily set and maintain the ideal temperature. This helps you save money on your heating bills by ensuring maximum comfort and minimizing energy waste.

The size and efficiency of the electric boiler should be taken into account when selecting one for your house. A boiler with a specific heating capacity might be necessary for a 100-square-meter home in order to provide enough warmth throughout. Choosing a high-efficiency electric boiler can also help you save even more money on energy and lessen your environmental impact.

In conclusion, an electric boiler is a compelling option when choosing a heating system for your 100-square-meter home because it comes with a number of advantages.
