Features and selection of a gasoline generator for a gas boiler

An electric heating boiler occupies a special place among other heaters because it is operated without the need to replenish fuel supplies. Gas, which also does not have to be stored, is not available everywhere, unlike electricity.

Induction heater

Simplicity and ease of connection have provided the widest distribution of the electric heater. It is installed in apartments and summer cottages. It is found in northern and southern latitudes. Basically, these are 220 volt units, since the required power in this case does not exceed 12 kW.

A more powerful electric heating boiler is three-phase and requires a 380 V connection.

The advantages of an electric boiler

The three-phase electric boiler is constantly being improved by the developers. Wall and floor models are available.

The best representatives of this class receive additional systems and devices that provide multi-stage regulation, automation of air removal and temperature control processes.

An electric three-phase heating boiler is capable of working in conjunction with other types of heaters. Compactness and design are considered indisputable advantages.

Although an electric heater is not as economical as, say, a gas heater, it still has certain advantages:

• An electric boiler takes up less space than a solid fuel one. It is allowed to be mounted anywhere where there is an electrical network;
• No chimney or additional ventilation is required - this is a direct saving of money and time for maintenance;
• Not a source of unpleasant odors and carbon monoxide. The boiler is environmentally friendly.
• Almost no noise during operation;
• The absence of open flames makes it easier to comply with fire safety measures.

Electrode boiler

Electric boilers have high efficiency - at least 96%.

The disadvantage of a three-phase boiler is the need to convert the current to 380 V and the presence of good electrical wiring in the house. Electricity is more expensive than gas, and frequent power surges affect the quality of the boiler. This also applies to the minuses.

Inverter gas generators for gas boiler

At the moment, this is the most modern type of generator. Its main difference and advantage is the presence of an inverter, which provides an accurate sinusoidal voltage.

Advantages of inverter type gas generators:

• Small dimensions of the device. They have one and a half to two times smaller dimensions than models without inverters.
• Stable voltage. Thanks to the built-in voltage regulator, the output device produces electricity that is almost ideal in its characteristics (voltage of 220 volts at a frequency of 50 hertz). Therefore, manufacturers of expensive gas heating boilers recommend using this type of device with their equipment.
• Cost effective and energy efficient. The design feature of the inverters is the presence of a special module that controls the engine speed, which significantly increases the efficiency of the units.

The main disadvantages of inverters include their high cost.

Varieties of electric boilers

The electric boiler is presented on the market with a wide variety of products. The differences between them are as follows:

• The number of contours. Like other types of heaters, an electric boiler can be single and double-circuit. A single-circuit boiler has a slightly higher output power, since it does not provide for operation with hot water supply.
• Heating element type. It can be a heating element, an electrode or an induction coil (inverter).
• Coolant type. Some single-circuit heater models use antifreeze.
• The type of electrical network used (220 or 380 volts) and the connection method (single-phase or three-phase).
• Heating method. The boiler is of a flow-through or storage type.

To create the increased power, more electrical system performance is required. An electric heating boiler with a capacity of over 12 kW is recommended to be connected to a 380 V network. This requires obtaining a permit and pulling a separate line.

With insufficient water pressure, it can boil!

Installation of an electric heating boiler, connection to power supply

In addition to the plumbing connection of the electric boiler (piping), the most important task when installing an electric boiler is to correctly connect the electric boiler. As they say, this work should be done by professionals, but information on this issue will be useful to you.

• For an electric boiler, you need to allocate a separate power line from the input-distribution board of your house;
• The boiler power supply line must be protected by a circuit breaker with a rated operating current slightly higher than the operating current of the electric boiler at maximum mode (this data is in the boiler passport);
• The body of the electric boiler must be grounded by the third (220 V) or fifth (380 V) wire in the power supply cable. For the earthing of the electric boiler, separate earthing wires must not be used;

In the input distribution device (ASU) of the house or the electrical panel of the house, the boiler power cable is connected as follows:

• The phase wires of the power supply L1; L2; L3 are connected to the output terminals of the three-phase circuit breaker. The circuit breaker is separate, only for the electric boiler.
• Zero working wire (N) is connected to the zero bus (terminal block) of the shield;
• The ground wire is connected to a separate bus in the switchboard marked "Ground".
• With a single-phase (220 volt) power supply to the boiler, the three-pole circuit breaker changes to a single-pole one. The rest of the connections remain unchanged.

Important! Do not confuse and do not combine the connection of the zero working (N) and grounding, protective (PE) wires for three-wire and five-wire connection of the electric boiler.

The principle of operation of electric boilers

The work algorithm is simple. First, the coolant is supplied to the expansion tank. It is then heated by electrical energy and then sent to the system.

The design implements the following heating schemes:

• With the help of heating elements. One or two heating elements connected to the network heat the water in the tank like boilers. The heating element boiler is reliable, gives high efficiency and is relatively inexpensive.

Heating element heater device

To increase efficiency, the use of programmers is recommended. These devices provide automation of work depending on the indoor or outdoor temperature. The economic effect from the application is up to 30%. Installation is permissible on our own, but it is better to provide work to professionals.

• The electrode boiler uses the principle of AC heating when passing through water (heat carrier). Automation protects such a boiler from short circuits, leaks and overheating. These devices are sensitive to water quality.
• The induction type boiler uses the principle of heating by electromagnetic induction. The heating element is a coil with a large number of turns of insulated wire and a metal rod in the middle. It is placed in an upright position in a sealed cylindrical body, inside which a coolant is supplied through the lower branch pipe. Power is supplied through terminals installed on the top of the cell body. After heating, it is discharged into the system through the upper pipe.Boilers of this type heat up quickly, which requires monitoring the pressure and the presence of water in the system.

Types of gas generators for a gas boiler

By the number of engine strokes, generators are divided into:

• Two-stroke;
• Four-stroke;

The first type has much smaller dimensions and relatively low cost. And the second type is more economical and reliable.

According to the design of the engine, they are distinguished:

• Synchronous generators
  ... The disadvantage of this type is the short service life of the contact brushes (although the most modern models are already equipped with a brushless system). The advantages include resistance to starting loads and stable (without large drops) voltage in the network.
• Asynchronous generators
  ... Motors of this type do not have windings, which ensures simplicity of design and reliability. Disadvantages of this type: high sensitivity to inrush currents and voltage surges.

By way of inclusion:

• Gas generators with manual start. When the electricity supply from the main source is interrupted, it is necessary to manually start the generator, and after the main source of energy is restored, turn off the unit.
• Gas generators with automatic start. With the help of electronics, the gas generator will automatically turn on in case of malfunctions in the main network, and also turn off automatically if necessary.

Types of three-phase heaters

The three-phase boiler is characterized by increased performance, quiet operation and compact dimensions.

Homemade induction heater

They are more often used for heating and hot water supply systems in country houses. Double-circuit models are especially popular. Recommended to be installed in combination with other heaters.

Available in two types:

• Electrode. The advantage of such a boiler is the high heating rate of the coolant.
• Induction. This is the most innovative look. Provides low specific power consumption. The disadvantages include a large mass and a relatively high price of equipment. Such units are not produced with high power. To increase it, the method of cascade installation of three heaters at once is used, in which each boiler is connected to a separate phase.

Boilers with heating elements are also produced, but their popularity in private households is declining. Heating elements often have to be cleaned and changed.

Operating rules

Despite the fact that an electric boiler is rightfully considered one of the safest, do not neglect the observance of safety measures during operation. This is especially true for connection.

Primary requirements:

• The connection is made directly to the meter through circuit breakers. Protection ensures safe shutdown of the heater in case of short circuit and sudden voltage surges.
• Correct grounding is essential. There is a scheme in the manufacturer's instructions, non-observance of which entails a waiver of warranty obligations.

Connecting the boiler to the network

During operation, monitor the condition and performance of the so-called safety group of an electric boiler:

• a safety valve that relieves pressure when the permissible values ​​in the system are exceeded;
• pressure gauge - incorrect readings will not allow you to determine the malfunction in time;
• air vent - this design element prevents air from entering the system. Airing is fraught with interruptions in operation, boiling and even failure of the boiler.

The boiler operation is monitored by the automation and control system, which periodically require checking.

Automation regulates the temperature regime, and in case of failures, it issues a shutdown signal. The performance and power of the heater depends on its work. The service life of the elements is 5 years or more, but visual inspection of the operation is recommended by the manufacturers.

It is believed that electrically boilers are safer than others. If installation and operation are carried out in compliance with all requirements, then the boiler can work without problems for 10 or more years.

Piping and first start-up of a three-phase boiler

They begin to mount an electric three-phase heating boiler from the calculation of the circuit. It is somewhat more complicated than when connected to a 220 V network, but it is present in the passport to the unit. Since you will have to obtain permission to operate the boiler in the 380 V network, it is better to entrust the connection to the employees of the electric networks.

The most critical part is connecting the wires. The order is indicated in the instructions and is absolutely uncomplicated. The main thing is to observe the color and properly ground the unit.

Three-phase connection diagram

It is important to correctly perform the strapping. Correct strapping is a guarantee of high-quality operation of the device. This will require a number of accessories and tools. The work is not difficult for a person who has an idea of ​​plumbing work.

Water must enter the boiler through the return line. This is done in order to be able to add water during the operation of the boiler without the occurrence of cavitation processes. A shut-off valve is installed in the supply line, and a filter is installed in the discharge line.

The same taps are needed in the water supply lines to the heating and hot water systems.

The boiler is mounted at the lowest point of the system. This will allow you to get the maximum heating of the heating system elements. The pipe for supplying the coolant to the radiators is installed at a minimum height from them.

A double-circuit heater must be connected so that the coolant in the small circuit heats up to a certain temperature and is supplied to the large circuit to the radiators.

After the connections are completed, start up. First, remove the front panel and slightly open the tap in the return line so that water begins to flow into the tank.

The control is carried out using a pressure gauge on the device body. The required pressure is limited by the green sector on the device (1.5-2 bar). When the arrow enters this sector, unscrew the cock on the relief valve (installed in the upper part) and completely bleed the air. When water flows without bubbles, it is closed. This will cause the pressure in the tank to drop. Wait until it grows and then bleed the air again.

Electric boiler control unit

Then proceed directly to the start-up. To do this, include a gas station. The power lamp on the indicator of the device will light up and digital data on the water temperature will appear.

Pressing the arrow buttons (+ and -) controls the amount of used kW and the water pressure in the boiler. The Mode and OK buttons allow you to program the temperature and power consumption in kW.

After the set temperature has been reached, the pump starts functioning and the heating element turns on. All that remains is to close the lid and enjoy the quiet and fast work. The boiler is stopped by pressing a button with a minus sign and a complete reset of the set temperature.

How to connect a gas generator to a gas boiler

First of all, when connecting a gasoline generator to the boiler, you need to carefully read the technical documentation of the generator and boiler and strictly follow it.

It is imperative to ground both the generator and the heating boiler. This is necessary not only to ensure electrical safety, but also so that a pronounced "zero" appears in the generator. Without this, the boiler flame detection system may not work.

For the boiler to work properly, the sine wave of the output current must be exactly 50 hertz, otherwise the boiler may not start.A voltage regulator or buying a high-quality inverter generator will help to cope with this task.

An important point in the operation of a gasoline generator is the removal of exhaust gases from the premises. To do this, you need to equip a chimney or a ventilation system in the room.

Modern owners of houses and apartments strive to do everything in order to provide their families with comfort and coziness. One of the conditions for a comfortable stay is the warmth in the premises during the winter months and in the off-season. The surest way to ensure climatic comfortable conditions, independent of external factors, is to install a gas boiler.

This device can continuously heat the premises, and also, which is important, supply hot water to the house. Solving the heating issue in this way ensures the complete independence of homeowners and their families from the central networks, gives them the opportunity to regulate the temperature themselves and warm up when necessary. An ideal solution for an autonomous heating system would be to connect a gas generator to it for a gas boiler.

Choosing a brand of electric boiler

Today, buying a three-phase boiler for heating does not seem to be problematic. There are a great many manufacturers and versions.

The choice is not easy to make. Be sure to pay attention to the features available and the warranty. Buyers' trust was formed under the influence of subjective and objective factors. The most popular brands are produced today in Germany, Czech Republic, Spain and Switzerland.

German samples Bosch Wespe Heizung and Swiss STS are distinguished by high performance, but also by the same high price.

Wall-mounted units of the Bosch Tronic 5000 H series are used in various heating systems, including together with storage tanks. These are boilers of heating element type. They are installed in three pieces.

Bosch Tronic 5000 H

Single-circuit heaters are suitable for hot water supply using an indirect heating tank. The efficiency declared by the manufacturer is 99%. They provide water heating up to +90 degrees, four-stage power and temperature control using a room regulator.

Slovak boilers Protherm are distinguished by no less functionality and performance at an adequate cost. The same equipment is supplied by the Czech company Dakon - the Protherm 18K model, like the German ones described above, is equipped with a steel heat exchanger and automation, which provides even greater possibilities with the same efficiency. The boiler has the function of remote power supply control from the tariff meter.

Russia produces products that are not inferior in quality, but more affordable in terms of cost. The company SAVITR (part of NPK VETROSTAR) has been producing dual-circuit boilers of the Ultra series with weather-dependent automation and remote control with a GSM module since 2010. According to reviews, the quality and reliability are the highest.

Russian manufacturers have extensive service networks, which is important.

Tips for choosing a generator

When choosing a generator for a gas boiler, pay attention first of all to power, efficiency and ease of operation. Based on your material capabilities and the conditions in which the installation will be used.

Remember that fit synchronous devices... If funds allow, consider buying an inverter type, which is best suited in this case.

Below you can see a small video on choosing a generator for a gas boiler:

Calculation of heating costs

As mentioned above, economically an electric three-phase boiler is more expensive than its gas and solid fuel counterparts. Electricity rises in price by leaps and bounds.

Electric boiler piping diagram

Calculate the flow rate for a month or heating season in the following way:

• given that the efficiency of most units is close to 100%, it is believed that to obtain a kilowatt of thermal energy, 1.03 kW of electrical energy will be required;
• the area of ​​the house is divided by 10 and multiplied by this indicator;
• multiply the resulting value by the cost of one kW / h. (in different regions it is different), then by 24 (the number of hours of work per day) and the number of days in a month or heating season.

In theory, for a house of 100 square meters with a kilowatt cost of 3.2 rubles and round-the-clock work per month, about 26 thousand rubles will be required for heating. In practice, this amount should be reduced by about half - the boiler does not always work around the clock. The expenses will be even less for the apartment.

The video shows the installation procedure:

The material from which the house is built, floors are made, the type of windows and doors, the quality of insulation have a great influence. It is not possible to take everything into account. Therefore, only practice will show how expensive the boiler will cost.
