Comparison of the efficiency of heating of a private house with an electric boiler and convectors

Selecting the ideal heating system for your house is essential for both efficiency and comfort. It can be difficult to decide which of the many options available is best for your requirements. In this piece, we’ll compare electric boilers and convectors, two common heating options for individual homes.

Let’s investigate electric boilers first. These systems heat the water by using electricity, and the heated water is then distributed throughout the house via radiators or underfloor heating systems. Electric boilers are a well-liked option for homeowners searching for a hassle-free heating solution because of their reputation for simplicity and ease of installation. They can also be remotely operated, which provides convenience and flexibility in controlling the temperature in your house.

Conversely, convectors work by pulling in cool air, heating it with electricity, and then redistributing it throughout the space. These units are perfect for places that need to warm up quickly because they are usually mounted on walls and give off quick, focused heat. Because convectors heat up quickly and don’t require a lot of water like traditional boilers, they are also energy-efficient.

A number of factors are taken into consideration when comparing the efficiency of convectors and electric boilers. Total operating costs are an important factor to take into account. Convectors may be more expensive initially, but over time, especially in areas with high electricity prices, electric boilers may prove to be more costly. Convectors, on the other hand, provide accurate temperature control and instant heat, which may result in lower energy costs.

The size of the area that needs to be heated is another thing to think about. Larger homes with several rooms are better suited for electric boilers because they can heat the entire house evenly. Conversely, convectors work better in smaller rooms or places that need extra heating, like home offices or bedrooms.

In conclusion, there are benefits and cons to both electric boilers and convectors for heating a private home. In the end, the decision is based on your personal preferences, financial situation, and needs. You can make an informed choice that will keep your house warm and cozy for many years by weighing the advantages and disadvantages of each option.

House heating electric boiler

Situations where electric heating boom is more cost-effective and cozy include:

• heated area of the house 100 or more square meters;
• It is possible to purchase electric boots of the middle and higher price segment (35-40+ thousand. rub) with advanced automation, the presence or ability to connect a room thermostat;
• It is planned to connect a buffer capacity to the electric boiler, which will accumulate excessive heat.
• In the priority of the comfort and flexibility of the heating system.

We will examine each point in greater detail.

First off, the majority of convectors cost between 2,700 and 5,000 rubles and have a 1.5–2 kW capacity. This indicates that seven 1.5 kW convectors or six 2 kW convectors (22–25 thousand rubles) are needed for a home measuring 100 m³.

Such convectors are not safe to connect via a rosette to a traditional power supply, and their total cost is nearly as high as that of the reasonably priced models that are both functional and economical. As a result, the cost of the convectors increases with the heated area, but the cost of the boiler hardly changes as the amount of heat produced increases. However, if the radiator system is not yet organized, don’t overlook it.

Second, because standard convectors’ heating elements always run at maximum power and shut off when the temperature rises or falls by one or two degrees, they overheat the air (it’s also important to consider the thermostat’s poor accuracy). Furthermore, every extra degree equals 3-6% of the extra consumption. Even the most affordable electric ship models can maintain a specific temperature more precisely and steadily with three power adjustment steps.

The most affordable electroCKs have the option to connect an external indoor thermostat (cost of problem: 1-1.5 thousand rubles); one such example is the popular promerm slot 9 KR 13 (approximately 35,000 rubles). Using a room thermostat, you can program the parameters of work for the next day or a week, for example, lowering the temperature to 15 °C during working hours, when there are no hosts at home. In addition, the boiler’s operation is more precise and accurate depending on the room’s temperature.

We stand to save thousands of rubles as a result of this operation. The room thermostat’s functionality is limited to pricey convectors that cost 8–9 thousand rubles.

Thirdly, you can add to the buffer emksota system—a sizable tank that stores extra heat and subsequently provides them with a heating system or hot water supply—after raising the initial costs for additional payback.

The most well-known scheme involves storing as much heat as possible during the nighttime electricity tariff period—which is more than twice as cheap—because radiators will then continue to receive heat from the buffer capacity for an additional three to seven hours. The sensible plan calls for a sizable buffer volume, a sizable boiler power reserve, and a sizable portion of the house—particularly the frame.

It’s also important to note that, unless there are steel panel models with convection ribs, the heating system’s radiators do not dry the air in a heated room. However, coordination with energy supervision authorities is necessary for the installation of an electric boiler with a capacity greater than 10 kW.

Advantages and disadvantages

In summary, weighing the benefits and drawbacks of heating systems that use radiators and electric booms:

When evaluating a private home’s heating efficiency between convectors and electric boilers, a few important considerations must be made. Electric boilers are generally more expensive to operate, particularly in areas with high electricity prices, even though they provide uniform and even heating throughout the house. Conversely, convectors heat quickly but may find it difficult to keep a room consistently warm in larger ones. The effectiveness of either heating method is also significantly influenced by the house’s layout and overall insulation. In the end, the decision between convectors and an electric boiler is based on personal tastes, financial limitations, and the particular heating requirements of the home.

What is the difference between heating of a private house by electric convectors

In these situations, convectors are more advantageous and cost-effective than electric boots:

• heated area of a private house less than 80-90 m 2;
• It is planned to buy expensive models with accurate electronic control and the ability to combine devices through a general thermostat or application;
• Temporary residence in the house, when the lower operational costs of the electric boiler will not pay off the high cost of buying and installing the entire system.

The most common misconception is that "convectors are more economical than an electric boiler because, when they operate, thermal energy is transferred to the room immediately (convector → air), whereas the thermal energy generated by the electric boiler passes through a cycle that goes Electric boiler → Coarler → Wiring in C → Radiators → Air."

This is accurate, but it’s also important to take into account the previously mentioned factors: an electric boom for more stable temperature maintenance; stepped or even smooth power adjustment; and the option to operate using data from an external thermostat. All of these factors are significantly impacted by efficiency, which is supported by user feedback and actual use.

The exception is when low-cost electric boilers are contrasted with high-end convectors (between 8 and 9 thousand rubles) and stepped power adjustment without external control.

Which in the end is more economical and effective: electric boiler or convectors

As previously stated, the decision is based on the size of the private residence as well as the type of electric boiler or convectors.

You can safely choose 2-4 convectors with a capacity of 2 kW each for a house that is between 40 and 80 m³. The total cost of the solution will be between 5,500 and 10,000 r. + the organization of separate wiring for their nutrition, t.To. Long-term use of such powerful devices is just dangerous and prone to frequent overloads.

Large operating costs for 5-20% will be covered by the minimal costs of arranging heating for many years. If you have more money to spend, you can consider the more costly Noirot, Electrolux, Ballu, or Nobo models to improve efficiency and management comfort.

The decision is still not clear for homes between 80 and 120 m³, as the advantages of high-quality electric boilers are already well-established, and the overall cost of convectors is already comparable to that of setting up a heating system with an electric coil and radiators.

For homes that are at least 120–300 square meters in size Using an electric boiler is preferable. The external indoor thermostat will make the heating system much more tangible and stable. Additionally, a powerful electrical appliance will be connected at a single point, making it easy to solve hot water supply issues, connect warm floors, and make sensible use of the buffer capacity.

How to precisely determine the boiler’s required power? Each calculation, formula, and corrective coefficients

It’s evident from closely examining the heating methods’ efficiency for a private home that convectors and electric boilers each have advantages and disadvantages.

A centralized heating solution is provided by electric boilers, which ensure even warmth throughout the house. Many homeowners find them to be a convenient option because they are comparatively simple to install and maintain. However, variables like the cost of electricity and the quality of the insulation can affect how efficient they are.

Conversely, convectors provide localized heating, which makes it possible to regulate the temperature in each room more precisely. In smaller spaces, they are frequently more energy-efficient than electric boilers; however, in larger areas or poorly insulated homes, their effectiveness may be compromised.

A private home’s size, insulation levels, and financial constraints should all be taken into account when deciding between an electric boiler and convectors for heating. Finding the best choice based on unique requirements and circumstances can be aided by speaking with a heating specialist.

In conclusion, the question of which heating system is more effective for a private home cannot be answered in a generalized way. Convectors and electric boilers each have benefits and drawbacks, so the best option will rely on personal preferences and needs.
