Profitable investment: autonomous mini boiler rooms for private homes and cottages

Recommendations for choosing a new generation mini-automatic machine

In addition to the characteristics considered, it is worth paying attention to some more features:

• Power - calculated individually for each type of boiler. The power determines whether the heating of the room will be sufficient.
• Efficiency—for electric boilers, the efficiency factor is high—95–98%.
• Power adjustment can be stepped or smooth. In models with an independent heating element, step adjustment is used. Smooth is possible only in devices with a rheostat.
• Price depends on many indicators: type of electric boiler (heating element, ionic), power, manufacturer, additional functions.

Reference! Particular attention should also be paid to the size, weight of the electric boiler, efficiency, and the type of room it will heat.

The main criteria for choosing electric boilers for a summer residence

When selecting an electric boiler for heating a dacha, the most important thing is to correctly select the optimal power of the device in order not to spend extra money and not freeze at low outside temperatures.

The power directly determines the size of the room the boiler can heat. If it will be used only for heating, the power is calculated from the ratio of 0.1 kW per 1 m2 of area.

To heat hot water, additional load will be required, based on the number of water users and the level of plumbing equipment in the house.

In order to make a choice of an electric boiler, you will need to calculate the heat load at the dacha and take into account the following data:

• dimensions of the heated house;
• degree of thermal insulation of the object;
• building materials from which the structural elements of the building are made;
• existence/absence of a smoke ventilation system;
• number and characteristics of window and door openings;
• temperature characteristics of the region where the object is located.

Carrying out maintenance

It is worth noting that. Like any other heating device, electric boilers require maintenance of some components. And all this work must be carried out both at the beginning of the heating season and at its end.

The regulations for the necessary technical work include, first of all:

1. Disabling the main electrical module;
2. After which you should clean the module from dust and other contaminants;
3. Conduct a visual inspection of all module pipelines to ensure that there are no possible leaks;
4. Next, dismantle the protective plugs and check the quality of fastening of the working contacts; if a loose connection of the contacts is detected, tighten them.

That's practically all that concerns service. You can install the plugs in their standard places, connect the power to the main module, and start the system. It is also worth saying that for the most part this work is carried out by specialized organizations that sell and install these units. But as can be assessed in general, this procedure does not have any subtleties, and it can be completely done independently.

As for current repairs, its regulations will be as follows:

1. The first thing to do is turn off the power to the module;
2. Carry out work to clean it from dirt and dust;
3. Close the system ball valves;
4. Unscrew the polyamide nuts securing the electrodes;
5. Clean the electrodes and the inside of the module from scale formation and blockages;
6. Inspect the fastening of the contacts and, if necessary, dismantle them, clean them and install them in their normal place;
7. Assess the condition of the temperature sensor;
8. The final stage of work will be the sequential reassembly of all components and installation of all plugs and protections in place. Next, you need to open the system taps to provide power and start the system.

Very important: to maintain the unit in working condition and prevent premature breakdowns, maintenance of the unit must be carried out at least once a year

Climatic offers a wide range of electric boilers of various capacities. Read the information or call our consultants to choose the right boiler model.

Electric boilers are designed for heating a private house, cottage, apartment (including apartment heating)

, various administrative, commercial and industrial facilities ranging from 30 to several thousand square meters. m. Electric heating is optimal where there is no main gas or where there are strict requirements for the environmental friendliness of heating devices. Also, an electric boiler is often used as a backup heating option in case problems arise with the main boiler, for example, a gas one.

An electric heating boiler consists of a heat exchanger, a block of heating elements, a control unit and control and safety devices. Some electric boilers are equipped with a circulation pump, expansion tank, safety valve and filter. The coolant heated by electricity circulates through a system of pipes and radiators, providing space heating, as well as heating water in the boiler. An electric double-circuit boiler is used for heating and hot water supply, a single-circuit boiler is used only for heating a house, as well as for heated floors.

pros

: Compared to boilers using other types of fuel, electric boilers are cheaper, more compact, safe and silent. Connecting electric boilers is much simpler and less expensive than other types of boilers. Due to their compact size and light weight, electric boilers are wall-mounted, do not require a separate boiler room, and installation is allowed in utility or utility rooms, storerooms, kitchens, basements, and even living rooms. Electric boilers are easy to operate and do not create harmful emissions and foreign odors, do not require constant maintenance, expensive cleaning and regular fuel purchases.

Minuses

: Dependence on the stable availability of electricity and high demands on the quality and reliability of electrical wiring. You should also take into account the fairly high cost of electricity. To make an informed decision about purchasing an electric boiler, it is recommended to make a preliminary calculation of electricity costs.

The boiler will be used in the Russian climate on average from September to April inclusive, i.e. only 8, not 12 months a year. In autumn and spring, the boiler will be used at a minimum, in winter - at full capacity. Thanks to the built-in automation, the boiler will not operate continuously, on average - about 8 hours a day, so the approximate energy costs for the year can be calculated using the following formula:

240 days X 8 hours a day X boiler power X cost of 1 kW of electricity

Electric boilers with a power of up to 12 kW are available in single-phase (220 V power) and three-phase (380 V power), and boilers with a power of more than 12 kW are only three-phase. Most electric boilers with a power of more than 6 kW allow multi-stage power adjustment.

Various remote programmers that can maintain the room temperature according to a user-specified schedule help save energy without sacrificing comfort.

To select an electric boiler, you need to find out the power of the device. Basic calculation - 1 kW of boiler power is enough to heat 10 m2 of a well-insulated room with a ceiling height of up to 3 m.

To select a specific electric boiler model, you can contact the consultants of the Termomir company. Remember that in addition to the boiler itself, it is necessary to purchase other elements of a complete heating and water supply system (radiators, pipes, pumps, thermostats, boiler and much more), so it is better to entrust the selection of equipment and its complete set to professionals.

Currently, our company’s product range includes both the best electric boilers from European manufacturers and good inexpensive Russian electric boilers.

The use of mini-boilers for heating soil in greenhouses.

Water heating of greenhouses is a universal way to simultaneously heat both air and soil.

ADVANTAGES OF WATER HEATING GREENHOUSES:

• uniform heating of air and soil;
• automatic temperature control of the coolant leads to energy savings;
• a water heating system does not reduce air humidity in the greenhouse;
• The condensate formed on the water pipes moistens the soil and is very beneficial for plants.

The autonomous mini-boiler “ThermoGnome” will ensure the operation of the greenhouse’s water heating system in automatic mode.
When laying the heating system, we recommend using a corrugated stainless steel pipe.

ADVANTAGES OF USING STAINLESS STEEL CORRUPTED PIPE FOR A GREENHOUSE:

• The heat transfer area is significantly larger compared to a smooth pipe. (at the same time, stainless steel is one of the best heat transmitters)
• stainless steel pipe does not attract rodents;
• Corrugated pipe due to corrugation is not subject to defrosting

Why is a turbine needed?

Heating boilers, as a rule, have quite large dimensions. This is due to the need to obtain a large volume of oxygen needed for fuel combustion. Accordingly, to increase power it is necessary to expand the combustion chamber and air ducts. However, a turbocharged double-circuit wall-mounted gas boiler takes up quite a bit of space and is content with a very small combustion chamber. What is his secret?

In this design, air does not enter the combustion chamber naturally, but is forced under pressure. Floor-mounted and wall-mounted gas double-circuit turbo boilers use powerful fans (turbines) as a means of supplying air and removing exhaust gases. In this case, the combustion chamber itself remains closed and does not communicate with the room in which the boiler is installed. Thanks to this, turbocharged boilers not only have great power, but are also absolutely safe.

Boilers with a closed combustion chamber must be installed close enough to an external wall to ensure adequate air flow. If this is not possible, large-diameter pipes are used to supply air, but they should not be long. Experts indicate that the optimal length of the air duct is up to 3 meters.

Important! When installing a turbocharged boiler, it is necessary to provide high-quality protection from wind, which can significantly change the characteristics of the air flow inside the combustion chamber. In addition, it is desirable to prevent moisture from the ambient air from entering the combustion chamber

Liquid fuel boilers

A diesel boiler for a summer residence is very popular, the main type of fuel in which, as it becomes clear, is diesel fuel, as well as waste oil, and the latter option is very cheap. It is worth noting that the main reason for the popularity of these boilers is not their efficiency (while diesel fuel is significantly more expensive than used oil), but the ease of their operation. The advantages of such a heating element are:

• the equipment is equipped with a temperature control function, while in simpler designs it is possible to control only the heating of the coolant, then in advanced models it becomes possible to also change the air temperature in the room;
• the operation of the diesel boiler is fully automated, so there is no need to regularly load fuel manually;
• modern development technologies offer a completely new, innovative option for turning on the boiler - via SMS. This means that the equipment can be turned on remotely, for example, a few hours before arriving at the dacha, but in this case the boiler must be equipped with an automatic ignition function.

Among the disadvantages that diesel boilers have, the most obvious are:

• the cost of solar oil is very expensive;
• if the temperature is low, the boiler burner simply will not be able to ignite properly, and the fuel will become viscous. However, this problem can be solved by using so-called winter diesel fuel as the main fuel. Moreover, if you have electricity at your dacha, you can always preheat the room before turning on the main heating equipment;
• During operation, diesel boilers create quite loud and unpleasant noise, so there is often an inevitable need to place the structure in a separate room.

Advantages of buying electric boilers

For heating a dacha, 220 volt electric boilers are the best choice.
All that is needed to start using this equipment is to simply plug it into the network. Units of this type have many advantages over other heating devices. So an electric boiler for heating a 220V house is characterized by:

• High efficiency. As a rule, this figure exceeds 95%.
• Easy to install. There is no need to create a boiler room. This significantly simplifies the installation process and reduces financial costs.
• Silence. During operation, the unit makes virtually no noise.
• Reliable to use.
• Easy to use. The unit does not require constant maintenance. Therefore, problems such as the need for regular cleaning or replacement of nozzles do not arise.
• Minimum operating costs. Since electric boilers for heating a private house 220 volts do not require the cost of delivery and storage of fuel.
• Possibility of working in reserve. Electric boilers can function together with other heating equipment. Therefore, they can be used as a backup heat source.
• Compactness. Many wall-mounted boiler options are small in size. Floor-standing models are also quite compact. Therefore, there is no need to allocate a separate room to house the heat generator.
• Safety and environmental friendliness. During operation, a 220V electric heating boiler does not emit harmful combustion products. Therefore, a chimney is not needed.
• Availability of additional features. Some models are equipped with a step power control option. There are options with GSM remote control.
• High level of automation. The device is able to maintain the optimal temperature level in the house without outside intervention. All you need is to configure the device for a specific operating mode.
• Affordability in terms of cost: the price of an electric boiler for heating a 220V home is acceptable.

It’s true that electric boilers also have some disadvantages, for example:

1. Consumption of large amounts of electricity. Therefore, by installing such a device, electricity costs will increase.
2. It is not recommended to install boilers in areas with frequent power outages and power surges. Of course, you can install a voltage stabilizer and an uninterruptible power supply. But these are additional costs.
3. Heating element models are somewhat difficult to operate. Scale builds up on heating elements over time. Because of this, the device begins to consume more resources.

But, despite this, the advantages of electric boilers still outweigh the disadvantages, and to a significant extent. Of course, the price of electric boilers for heating a 220V apartment is considerable. But this disadvantage is gradually compensated by the increasing cost of solid fuel and gas.

Coal and peat heating of the dacha

Most often, these energy sources are used in combined-type boilers, which are capable of operating not on one, but on several types of fuel.

But there may be some division: there are models in which the firebox for two heat sources is common (for example, for coal and wood, for gas and diesel fuel), and there are models in which the combustion chambers are arranged separately. Of course, the first option will be more economical.

When installing heating in a dacha, it is important to remember that the comfort of living in the house will depend on the quality of its implementation. Therefore, in order not to spoil your holiday with low temperatures in the house, it is recommended to study in advance various photos of heating boiler options and determine which one is suitable for a particular structure.

Operating principle of an electrode boiler

The boiler design provides for connection to a closed heating system. And the entire cycle of its operation is controlled using built-in automation. It is the automatic controllers that regulate the temperature of the system, which can be kept between 20 and 90 degrees.

Also, a magnetic starter, which is built into the boiler controller system, monitors the drop in operating temperature and, if necessary, turns on the heating independently. After which it will also automatically turn off the system if it reaches the desired temperature range. In turn, the electrical network will also be protected from possible overloads that occur when the boiler is turned on, accompanied by increased loads. And in this case, the boiler will be helped by an automatic circuit breaker; when critical loads on the network occur, it will turn off the boiler until it is completely stabilized. The boiler system also includes coarse filters, which will protect the electric boiler from contamination and further decommissioning.

• It is worth saying that these units (electric mini-boilers) can be used to heat residential buildings, industrial warehouses, all kinds of industrial premises, country houses, and even greenhouses.
• It is also worth noting that these devices can work with heating systems, both with natural circulation of the working fluid and with forced circulation.
• In addition, Electric boilers can be used to prepare hot water using indirect heating boilers.
• Electric boilers can also be used in the construction of thermal curtains, for working with “warm floors”, for drying wood, in systems with combined water and electricity supply (wind generators, solar panels, centralized water supply, autonomous well with electric pump).

Mini electric heating boiler VEN-4.5 kW

One of the advantages of electric boilers is that these units can be installed in already working heating systems, in parallel with another heating device already installed (gas boilers, solid fuel boilers). In order to achieve the maximum effect from this device over large areas, it is necessary to install several such devices, thereby reducing the load on each unit separately and increasing its service life.

Top 5 best electric boilers for summer cottages

A necessary criterion for choosing an EC for heating a dacha is the level of equipment. An electric boiler with minimal components costs less, but in operation it is not a very good option.

You need to choose models with the maximum configuration, even if they are somewhat more expensive, in the future they will significantly simplify the process of heating the house.

Types of electric mini-boilers

In fact, an electric boiler is installed wherever there is electricity.

It is important that the electric boiler is connected to existing heating systems (gas, solid fuel), reducing the load on them.

Installation will not require special permission. Mini-electric boilers are divided into two types according to the type of modification.

heating elements new

The water in the system is heated using the heating element of the electric boiler: heating element. Inside it is a spiral of tungsten or nichrome wire, which heats up and transfers heat to the environment. The shell is made of steel, titanium or aluminum. A dielectric is placed between the shell and the spiral. More often this role is played by quartz sand.

Main elements of the heating element mini-automatic:

• heating element;
• heat exchanger;
• insulation;
• Control block;
• circulation pump.

Important! It is better to use distilled water in the heating system to prevent scale formation. This is the main “disease” of heating element boilers

The device has an automatic switch that turns off the device when the desired temperature is reached or in case of overheating.

Photo 1. New heating element mini electric boiler for a heating system with an automatic switch from the manufacturer Galan.

• The power is constant and adjustable.
• The temperature of the liquid does not affect the heating element.
• If there are several heating elements, then if one breaks down, the device will work.
• Various liquids are used as a coolant: water, antifreeze, antifreeze.

• If the heating element fails, it is replaced.
• The formation of scale on the heating element is the main disadvantage of this device. Because of this, the boiler fails or heats up weakly.

Attention! During operation, the heating element must be covered with water, otherwise it will burn out!

Ionic

The operating principle of new generation ion electric boilers is different. They do not have a heating element, and the energy conductor is water or a special liquid.

Electrodes are placed here, passing through which the current heats the liquid. Ion boilers are also called electrode boilers. They heat up quickly, unlike heating elements.

The ion electric boiler has the following elements:

• frame;
• electrodes;
• housing insulation;
• Control block;
• conductor of heat.

Some electric boiler models are equipped with a temperature sensor.

The system has built-in electronic control: when it cools down, the boiler will turn on itself, and when the desired temperature is reached, it will turn off. Works even with unstable voltage without turning off. Compared to a heating element boiler, an ionic boiler uses half as much electricity.

• reliability;
• fast heating;
• compactness;
• efficiency.

Photo 2. Ionic small boilers with electronic control from the manufacturer Galan consume a minimum of electricity.

• To fill, you need a special liquid or prepared water.
• Maintaining continuous fluid circulation.

Installation diagrams for a turbocharged double-circuit boiler

Depending on the size and design features, a gas double-circuit turbo boiler can be installed both on the floor and on the wall, or even in pieces of furniture. This becomes possible thanks to the relatively small size of powerful heating units with a turbine, as well as the presence of a closed combustion chamber that does not create a fire hazard. Let's consider the features of the main options for installing a turbocharged boiler.

Floor standing boilers

Vaillant atmoVIT

Boilers that are intended for installation on the floor are quite large in size and, therefore, high in power. Often this power is excessive for a small house or apartment. That is why, in most cases, floor-standing double-circuit boilers are used in enterprises or in large private houses with a height of 2 floors or more.

In addition to high power, the advantage of such models is ease of connection. All structural elements of a floor-standing boiler are located outside, which allows it to be connected to a gas pipeline and water supply system, as well as included in the heating circuit. At the same time, work on installing such a boiler can be carried out by workers without special skills. However, to supply gas it is still necessary to use the services of a specialist.

The main disadvantage of large and powerful floor-standing boilers, of course, is their high cost. In addition, they are heavy, which does not allow them to be placed in apartment buildings. And, of course, high power also means high fuel consumption, which can be excessive for a small room.

Wall-mounted and built-in boilers

Wall boiler

This category includes small heaters of low and medium power intended for heating private houses and apartments. Unlike floor-standing models, they are quite light in weight and have a fastening system that allows them to be placed on a wall or in furniture. Wall-mounted gas double-circuit turbo boilers are an ideal solution for cases where the installation of a heating system must be carried out in limited space.

Of course, such boilers consume less fuel and require lower costs. In addition, they can be installed hidden - that is, built into certain interior items. Built-in boilers can be located in different parts of an apartment or house - in the kitchen, bathroom or even pantry.

There is only one drawback that a turbocharged double-circuit wall-mounted gas boiler has. This is his power. As a rule, the heat produced by such models is enough to heat 180-200 sq.m. However, this indicator is quite enough to heat a large apartment or a medium-sized house.

Solid fuel boilers

As mentioned earlier, gas heating boilers for summer cottages are installed extremely rarely, which explains the need to install other systems.

One of the popular varieties of this equipment are solid fuel boilers for summer cottages, the operation of which is based on the use of energy obtained during the combustion of wood.

The advantages that such heating boilers for a country house have are the following:

• despite the need to regularly purchase firewood, such fuel will not cost much more when compared with a design such as, for example, a gas boiler for a dacha;
• in order to save as much as possible on heating costs using firewood, in the fall in the nearest forest you can collect a decent amount of dead wood, which can also serve as fuel;
• Wood, as you know, is an environmentally friendly material that can also provide a unique aroma when burned, which will be very useful in a country house.

However, solid fuel boilers for heating a country house also have some negative aspects, which usually include the following:

• the need to frequently replenish the combustion chamber with fuel. Wood burns quickly, so one load of heat should last no more than 6 hours. The exception is boilers operating on the principle of pyrolysis combustion, however, installing them in a small dacha will be extremely unprofitable;
• It is not possible to regulate the temperature in such structures. The only thing you can use is the damper;
• A large stock of firewood requires quite a lot of space for proper storage. In this case, it is especially important to equip a canopy over the fuel so that it does not get wet.

Heating boilers

The products of the Czech manufacturer Protherm meet all these requirements. The range of its boilers ranges from 6 to 36 kW. It is noteworthy that models with a power of 6 and 9 kW require connection not only to 380 V, but also to 220 V. Another foreign brand that is actively promoting in the domestic market is the Polish Kospel. This manufacturer starts with devices with a power of 2 kW, but does not include an expansion tank in its housing. Each electric boiler is energy saving thanks to the features of the control unit. The automatic mode provides smooth power modulation with an even load on the sequential circuit of heating elements. It is also possible to connect weekly programmers that control temperature amplitudes according to a predetermined pattern without human involvement. The unit has outputs to sensors that react promptly to weather changes and issue appropriate commands to increase or decrease electrical energy consumption.
