Electric boiler for home heating (100 square meters): characteristics. The best electric boiler for home heating according to customer reviews Gas boiler for 100 square meters

Which boiler is suitable for a house 100 km.m.

According to GOST, in a perfectly insulated house, heat losses are 10-12 kW, and it is recommended to choose a boiler with a capacity of at least 11 kW. But this is in the event that we have qualitatively insulated the roof, walls, foundation, windows, doors, as well as the gas pressure in the gas pipeline of at least 1.5 bar. Therefore, for heating a private house with a total area of ​​100 sq.m, I recommend choosing a gas boiler with a capacity of 14 kilowatts or more. Why power gas boiler must be at least 14 sq. t:

• A power reserve of 30% is needed so that the boiler does not work for wear at the limit of its capabilities.
• It is necessary to take into account heat leakage through the walls, roof, windows, foundation.
• Rarely used in private homes radiator batteries. Basically, only pipes are used that do not give such heat transfer as radiator batteries.
• It is also worth paying attention to the boiler efficiency indicator, the higher the efficiency, the less you will pay for gas.
  • Russian models of boilers have an efficiency of 50-80%.
  • European boilers have an efficiency of up to 95%.
• In addition to heating, we still need hot water, the higher the performance indicator hot water the better for us. For a comfortable bath you need at least 7 l/min hot water.
  • 11 kW - 3.5 -5.5 l / min.
  • 17 kW - Hot water capacity at t 35°C 5.5 -9 l/min.

How to calculate heat loss at home

To calculate heat loss, you can use our calculator.

Despite the abundance modern options heating for private houses, most consumers stop at a traditional and proven gas boiler over the years. They are durable and reliable, do not require frequent and complex maintenance, and the breadth of the model range allows you to choose the unit for any room.

The main characteristic of a gas boiler is its power, for the correct determination of which one should take into account a large number of factors. It is from right choice power depends on the comfort of the climate in the house, and the efficiency of the boiler, and its service life.

Why is an accurate calculation of the boiler power necessary?

A competent approach should be based on clear measurements that will allow you to see a complete picture of the heat loss of a private house. Buying a unit with excess capacity will lead to unreasonably high gas consumption, and, consequently, to unnecessary expenses. At the same time, the lack of boiler power can cause it to fail quickly, because in order to heat the house, it will have to work at high speeds all the time.

The easiest way to calculate the power of a gas boiler, which has been used for quite a long time, is 1 kW for every 10 square meters housing plus 15-20%. That is, from this simple formula it follows that for a private house with an area of ​​​​100 m², a boiler with a capacity of about 12 kW is required.

This calculation is very rough and is only suitable for houses with good thermal insulation and windows, low ceilings and in a fairly mild climate. Practice shows that not all private houses meet these criteria.

What data is needed to calculate the power of a gas boiler

For private houses built according to a standard project, with a ceiling height of about 3 meters, the calculation formula looks quite simple. In this case, it is necessary to take into account the building area (S) and the boiler specific power index (UMK), which varies depending on the climatic zone. He hesitates:

• From 0.7 to 0.9 kW in the southern regions of the country
• From 1 to 1.2 kW in the regions of the middle lane
• From 1.2 to 1.5 kW in the Moscow region
• 1.5 to 2 in the north of the country

Thus, the formula for calculating the power of a gas boiler for a typical private house will look like this:

M=S*UMK/10

80*2/10 = 16 kW

If the consumer, whose task, in addition to heating the home, will also be heating water, experts recommend adding another 20% to the figure obtained using the formula.

What other heat losses should be taken into account?

Even taking into account the climate zone cannot give a complete picture of the heat loss of a private house. Someone has double plastic windows installed, and someone else has not bothered to change the old wooden frames, someone, and someone has only one layer of brick between the street and the room.

According to averaged data, based on experts' calculations, the largest heat losses occur on non-insulated walls and amount to about 35%. A little less, 25% of the heat is lost due to a poorly insulated roof. Ideally, there should be a warm attic above the house. The bad one can take up to 15% of the heat generated by the boiler, like the old ones. wooden windows. We should also not forget about ventilation and open windows, which account for 10 to 15% of heat loss.

Thus, it turns out that not for every residential suitable at home common formula. For such cases, there are their own counting systems.

The concept of dissipation factor

The dissipation coefficient is one of the important indicators of heat exchange between a living space and environment. Depending on how well, there are such indicators that are used in the most accurate calculation formula:

• 3.0 - 4.0 is the dissipation factor for structures in which there is no thermal insulation at all. Most often in such cases we are talking about makeshift houses made of corrugated iron or wood.
• A coefficient from 2.9 to 2.0 is typical for buildings with a low level of thermal insulation. Meaning houses with thin walls(for example, in one brick) without insulation, with conventional wooden frames and simple roof.
• The average level of thermal insulation and a coefficient from 1.9 to 1.0 are assigned to houses with double plastic windows, insulation of external walls or double masonry, as well as with an insulated roof or attic.
• The lowest dispersion coefficient from 0.6 to 0.9 is typical for houses built using modern materials and technologies. In such houses, the walls, roof and floor are insulated, good windows and a well thought out ventilation system.

Table for calculating the cost of heating in a private house

The formula in which the value of the dissipation coefficient is used is one of the most accurate and allows you to calculate the heat loss of a particular building. It looks like this:

Qt \u003d V * Pt * k / 860

In the formula Qt – is the level of heat loss, V – is the volume of the room (the product of length, width and height), Pt – this is the temperature difference (to calculate it is necessary to subtract from the desired temperature in the room minimum temperature air, which may be at this latitude), k – is the scattering coefficient.

Let's substitute the numbers into our formula and try to find out the heat loss of a house with a volume of 300 m³ (10 m * 10 m * 3 m) with an average level of thermal insulation at a desired air temperature of + 20C ° and a minimum winter temperature of - 20C °.

300*48*1,9/860 ≈31,81

Having this figure, we can find out what power the boiler needs for such a house. To do this, the obtained value of heat loss should be multiplied by a safety factor, which is usually from 1.15 to 1.2 (the same 15-20%). We get that:

31, 81* 1,2 = 38,172

Rounding the resulting number down, we find the desired number. To heat a house with the conditions we set, a boiler of 38 kW is required.

Such a formula will allow you to very accurately determine the power of the gas boiler required for a particular house. Also, to date, a wide variety of calculators and programs have been developed that allow you to take into account the data of each individual building.

Solving the problems of organizing the heating system of their own home, the owner very often faces the difficult question of choosing the type of boiler equipment. It is good if the settlement has an extensive gas supply network - according to the total assessment of the efficiency and cost-effectiveness of operating costs with gas boilers so far, nothing compares. But, alas, these benefits of civilization have not yet come to everyone. are beneficial where there is access to cheap (sometimes almost free) fuel, but it requires a lot of space for storage and proper storage, and in terms of ease of use, of course, such boilers cannot be attributed to comfortable ones.

Power lines are now stretched almost everywhere. Therefore, in some cases, the use of electricity is seen as the most acceptable, and often almost the only way to organize home heating. True, the question immediately arises of the high cost of operating such a system. Let's, for example, figure out what kind of house 100 square meters is needed, get acquainted with the models of the corresponding equipment. It is quite possible that this will help the owner of suburban housing to make the right choice.

What are the general advantages and disadvantages of using electric boilers

To better visualize the advantages of water heating with electric boiler equipment, let's just make a small comparison with systems that use other types of fuel as energy carriers - natural gas, wood (or other types of solid fuel) or liquid hydrocarbons.

If we talk about the layout of the system itself, that is, the layout of pipe circuits and the installation of heat exchange devices, then there is no particular difference - all this requires careful planning, calculations, and large-scale installation work. But a completely different picture is when the question concerns the installation of a thermal energy generator (boiler) and boiler room equipment. It is in this segment of problems that the use of electric boiler equipment immediately presents a lot of "trump cards" that simplify and reduce the cost of the implementation of the entire project as a whole.

Gas equipment, undoubtedly, is currently the leader in terms of operating efficiency - based on cash costs for each kilowatt of thermal energy received. All this is true, but the launch of such a heating system will necessarily be associated with a number of organizational and coordination (read: bureaucratic), additional construction and installation and control and inspection activities. And all this - with the obligatory involvement of relevant specialists. In a word: any of the mandatory stages is both a waste of time and, unfortunately, a considerable amount of money.

The very supply and connection of the gas main to the house is in itself a huge problem associated with large-scale costs and lengthy trips to authorities. The installation of the boiler will also require the organization of a system for the removal of combustion products and high-quality ventilation - without this, no one will issue an operating permit. All installation work on the pipes of the gas pipeline, including inside the house, has the right to perform only the agreed circle of specialists. And given the monopoly position of the gas workers, one can imagine how much money all this will cost.

Solid fuel boilers will be economical if in the region of residence there is an opportunity to purchase (procure) the corresponding fuel at a low price. Agree, there are areas where there are considerable problems with this. The operation of such a heating system will require the creation of a certain supply of fuel, which entails additional costs for organizing proper storage and storage. This, moreover, is also the need for additional space on the site or in the house itself. (all this, almost to the full extent, also applies to liquid fuel boilers).

By itself, solid fuel equipment is quite heavy and large-sized, moreover, it always requires the creation of a certain “exclusion zone” around itself. As a rule, one cannot do without a dedicated boiler room, in which all existing requirements must be met fire safety. In any case, the conclusion of the fire inspectorate on compliance with established standards will be required.

Another disadvantage of this type of heating is the need for frequent intervention by the owners in its work - we are talking about a periodic fuel bookmark. Even boilers long burning this problem is only partially solved.

In addition, it must be admitted that of all existing heating systems, solid fuel is the most inertial, difficult to fine-tune.

Optimization of solid fuel heating - installation of a buffer tank

A number of disadvantages of a solid fuel heating system, if not completely eliminated, is minimized by installing an additional device. What is it, how it works and how to choose optimal model- about all this in a special publication of our portal.

Well, now let's look from the same positions at Benefits heating system with electric boiler.

• This equipment differs from all other types of boilers primarily in that it does not use the principle of fuel combustion, there is no open flame. Naturally, the level of fire safety only benefits from this.
• There are no exhaust gas emissions whatsoever. Even if you do not touch on the general environmental component of the issue, this advantage eliminates the need for a chimney system and additional supply ventilation. There is no risk of getting poisoned by combustion products.

• From the foregoing, a logical conclusion follows that it is not at all necessary to allocate a special room for an electric boiler. Compact models fit perfectly, for example, in a kitchen interior, and some become invisible even in residential areas.
• It is quite obvious that electric boiler equipment is the easiest to install. The main condition is to connect a high-quality power line to it with an appropriate cross-sectional area of ​​\u200b\u200bthe wires - any electrician will do this work. But coordination with energy supply organizations is very often not required at all. For example, if the design power of the boiler is in the range of 8 - 10 kW, and the power lines brought into the house are in a satisfactory condition, then the power of 15 kW standardly allocated to the owner should be sufficient.

In fairness, we immediately note that this may not be enough for a large house (besides the boiler, of course, other appliances also need electricity). The way out is to coordinate the supply of a three-phase power line to the house. But it will still be easier than in cases with gas or solid fuel equipment.

• Modern automatic protection devices make the operation of electric boiler equipment as safe as possible.
• Electric boilers are extremely easy to operate, very sensitive to precise adjustments of operating modes. Control panels modern models allow you to program the operation of the boiler for a day or even a week. Such devices are easily written out in modern concepts " smart home» or to remote control systems via communication lines - GSM or IP.
• Well, it should be noted that electric boiler equipment usually compares favorably with the price level, compared with solid fuel or gas.

Together with such a list of advantages inherent in electric boilers and limitations, which, by the way, usually come to mind first when assessing the prospects for such a heating system.

• The first and most important thing is, of course, the high cost of the electrical energy itself. It is necessary to carefully weigh your "home accounting" - whether the family will be able to pay considerable monthly bills.

Naturally, with such high operating costs, measures for the most effective thermal insulation of all building structures will come to the fore - otherwise such heating will “let anyone around the world”.

It would be wise to use the possibilities of preferential tariffs for electricity to the maximum. This will become especially beneficial if additional devices for accumulating thermal energy are used ( see the link above to an article about buffer capacity ). The control systems of modern electric boilers open up ample opportunities for this - with proper programming, the boiler will turn on only during the period of the preferential tariff, accumulating thermal potential for its use during the rest of the day.

• Such boiler equipment is entirely dependent on the continuity and stability of the power supply. It is still possible to deal with relatively low voltage drops - by installing a stabilizer, although devices with such a high current-voltage characteristic (about 10,000 VA) are quite an expensive "pleasure". Well, if sudden surges or periodic power outages in the network are not uncommon in the area of ​​\u200b\u200bresidence, then you can not think about electric boiler equipment (or have it only as an auxiliary system). Uninterruptible power systems of such ratings are so bulky and expensive that they negate all the visible advantages of using electric boilers.

The conclusion is as follows - despite the numerous advantages of electric boiler equipment, the available negative sides require from the owners an extremely balanced approach to the organization of such a heating system at home. And in order to correctly navigate in such matters, you first need to find out the main criterion - what kind of boiler power will be required for efficient heating of housing.

How to determine the required power of an electric boiler

General principles of calculation

The title of the article states that equipment is required for a house of 100 square meters. This value is, of course, indicative, and was chosen for several reasons. Firstly, it is as close as possible to the area of ​​most medium-sized country houses. And secondly, it is easier to operate with round values, proportionally fitting them to the actual area.

True, such a “fit” will be valid only when using a very approximate method for calculating the boiler power. This approach implies that for every 10 m² of area, 1 kW of thermal energy is required. According to this ratio, a boiler with a minimum heat output of 10 kW is required to heat a house of 100 m².

Extremely easy! But how accurate is this? Agree, a lot of questions arise, and the first of them suggests itself - and for which climatic region is this proportion fair? Further, why is the height of the room not taken into account, but only the area - is there a contradiction here? If you wish, you can "dig up" a bunch more claims to this approach. As a result, the error in the calculations, in relation to a particular house, can be quite large. Too low an indicator is the lack of heating at the peak of winter frosts. The other extreme is the purchase of expensive equipment with power indicators that remain completely unclaimed.

In addition, do not forget that the calculation is carried out specifically for electrical equipment. If you manage to "invest" in 8 ÷ 10 kW, then it is still possible to get by with single-phase models. But when more than 10 kW is required, then most likely it will be necessary to think over the issue of laying a three-phase power line and installing an appropriate boiler.

How to be, how to carry out the calculation with maximum accuracy? Let's take the liberty of suggesting a calculation algorithm, which is embedded in the calculator below.

The algorithm involves calculating the heat output for each of the premises of the house where heat exchange devices (radiators, convectors, "warm floors") will be installed, taking into account its individual characteristics. Any specific feature of a single room, affecting the total amount of heat energy required for heating, gives its own correction (increase or decrease) coefficient to the calculated value. Well, then it remains only to sum up the obtained values, which will show the required power of the electric boiler.

In the rather harsh conditions of most regions of our country, having a well-functioning heating system is an important task. And the heart of the whole system has always been a heat source or boiler. Today you can buy coolant heating devices various designs. They will differ both in their functionality and in the fuel used. Which one to choose is the decision of the owner of the house. But here it is important to choose a device that is suitable in terms of power. This is what will be discussed in this article. Here we will talk about which electric boilers for heating houses with an area of ​​​​one hundred square meters are better to choose.

Advantages and disadvantages of electric heating boilers

Many owners of private houses very often choose electric boilers for heating. This is facilitated by a number of advantages that these devices provide. Namely:

It is precisely such advantages as ease of installation and operation, low price, automation and high efficiency, make electric boilers quite popular for heating a private house. In addition, there is no need to worry about the purchase of fuel. But such high-tech equipment also has its drawbacks.

The disadvantages of electric boilers include:

• if electricity is supplied regularly, then the house will be warm. But the cost of this fuel is constantly growing. As a result, heating costs are also rising. Today, during the winter months, a 100-square-meter house can run into double digits for electricity bills;
• Another disadvantage is associated with power supply organizations. In many localities there is a limit on the amount of electricity supplied for one private household. Very often, these capacities simply may not be enough to maintain the desired temperature in the house;
• also to the minuses include the great depreciation of power grids, especially in rural areas.

But, if everything is in order with the supply of electricity, then using electric boilers for heating is the best option. And electricity costs will be high only in the cold months, besides you can control your consumption simply by reducing or increasing the power of the boiler.

Types of electric heating boilers

Before talking about the power of an electric boiler for heating a house of 100 square meters, it is worth learning about their varieties. Today on sale you can find a variety of models, which may differ in different parameters. Namely:

What equipment to choose is up to the owner of a private house. The main thing is that the power of the electric boiler is sufficient to maintain a normal temperature.

Calculation of the power of an electric boiler for heating a house with an area of ​​​​100 square meters

Making correct calculations of the power of heating boilers is an important task. The correctness of her decision will depend comfortable accommodation at home in winter.

When calculating, it is necessary to study some parameters of the house. Namely:

• volume of all heated rooms. This is the most important indicator. According to the requirements of sanitary standards, one cubic meter of space should have 40 W of heating power. Calculating the cubic capacity is quite simple. To do this, the area of ​​\u200b\u200ball rooms is multiplied by the height of the ceiling. In our case, taking the standard floor-to-ceiling distance of 2.7 meters, we get 100 sq.m. * 2.7 m = 270 cubic meters;
• you need to know the number of windows and doors in the house. Through these elements, heat can leave the room. 100 watts of heating power are added to each window, and 200 watts to the door. Let's take (conditionally) that in a house with an area of ​​100 square meters there are 6 windows and the same number of internal doors. So, 1800 W should be added to the power;
• you also need to take into account the coefficient of your region. It is no secret that in our large country winter is not equally cold everywhere. That's why for the southern regions, a special coefficient is taken 0.7-0.9, for the central strip it will be 1.2-1.4, and in the northern regions, where winter is the most frosty, the coefficient is 1.7-1.9. For home in middle lane Russia, let's take the average value of 1.3;
• since the house is an individual structure, it is surrounded on all sides by unheated areas. To compensate for the cold coming from the floor, attic and external walls, it is necessary to apply another coefficient equal to 1.5;
• also worth adding 20 percent in case of abnormally severe frosts and the same amount if you have a double-circuit boiler (for heating water for plumbing).

Given all of the above, you can calculate the required power of an electric boiler for heating a house with an area of ​​100 square meters.

270 cubic meters (the volume of all rooms) * 40 W we get 10800 W.

To this value we add the power necessary to compensate for the heat consumption from doors and windows. We get 10800 + 1800 = 12600 watts.

Now we multiply this value by correction factors: 12600 * 1.3 * 1.5 we get 24570 watts. We increase the power by 40 percent (in case of abnormal frosts and for heating water for plumbing), we get 34398 W or 34.4 kW. Exactly such power should have an electric boiler to create coziness and comfort in the house.

Conclusion

Electric boilers are a fairly common home heating equipment. They are relatively inexpensive, easy to install and safe to use. And if you correctly calculate the power of the electric boiler, then living in a private house will be comfortable even in the most severe frosts.

AT last years are becoming more and more popular electric boilers, which replaced the gas ones, because they have several main advantages. In this article we will talk about which electric boiler for heating a house of 50, 100 and 150 square meters to choose, what parameters should be taken into account and why.

The essence of the electrical heating equipment similar to gas. Only here thermal energy It is formed under the influence of a current that heats the heat exchanger in which the liquid moves.

Key Benefits

• they do not make noise during operation;
• do not require a chimney;
• easy to operate and maintain;
• do not burn oxygen in the house.

The only drawback is that it is sensitive to voltage fluctuations, which can lead to damage.

Varieties and differences

There are several types of electric boilers that differ in structure, connection features, efficiency, but are suitable for houses of 50, 100, 150 square meters. Consider the main ones so that you can navigate when choosing equipment.

heating elements

They got their name due to the presence of special heating elements - pipes, plates located in the heat exchanger. In one device, there can be up to eight such parts of 2 kilowatts each.

The heating level is regulated, depending on the design, either manually or by means of automated system. Manufacturers offer consumers big choice models, both single- and double-circuit, working on:

• water;
• antifreeze;
• oil.

During operation, you should constantly ensure that the heating elements are completely covered with coolant. If they are "bare", this will lead to overheating of the entire system and premature failure of the boiler.

Among the main disadvantages of TEN-heaters are:

• large dimensions;
• obligatory plaque formation;
• coefficient reduction useful action, which is caused by the gradual heating of the coolant.

The price for this type of system ranges from $50 and can rise to $1000 - it all depends on the size, power, modern electronics and control modules, as well as the brand name.

Electrode

These boilers use special electrodes. Water warms up perfectly due to the fact that it contains salts.

The main positive features of the electrode equipment are small dimensions, ease of operation and high safety. By the way, the efficiency of such models reaches 95%!

The negative aspects of the use of boilers of this type include the use of a coolant only with a salt content, as well as a relatively frequent replacement of electrodes.

The cost of the simplest electrode boilers is about $60.

induction

Possess relatively complex design, since they suggest the use of an induction coil, due to which induction is created when current is supplied - it is this that provides heating of the core located inside the coil.

Structural complexity has its positive characteristics - it allows you to significantly increase the efficiency, reaching an incredible mark of 99%.

Other positive features include:

• low energy consumption;
• the ability to use virtually any coolant;
• no scale even after long period use.

But among not the most pleasant qualities - the cost. It starts at $400 and can go up to $3,000.

Advice. If you have opted for an induction boiler, it is better to buy a more expensive model, abandoning the cheap ones - this will allow you to significantly save on the additional purchase and installation of valves, filters, and an expansion tank in the future.

Let's review the most popular models of electric boilers last year, which were appreciated by buyers. Consider models of different price categories and different manufacturers, with an optimal ratio of quality and price. The rating included only those models that, according to statistics, received more positive reviews and which are recommended by service center specialists.
