Many visitors to the Technodom online store contact us with a request to select heating boilers online. We are always ready to help them in this matter, especially since the range of our company includes many different types and models of equipment, suitable for literally any purpose. For example, if you need to select a gas boiler according to the parameters, then our consultants will be happy to provide you with all the necessary information. Before proceeding with the selection of heating equipment, it is advisable to determine which of its criteria will be most important for you.
Selection of the boiler by parameters (area, power, type of fuel)
Very often people carry out the selection of a gas boiler for a private house in terms of area and volume of the room. This principle works effectively with other types of boilers. With this data, you can determine the optimal equipment capacity for your building. It is believed that the ideal performance should be 100 watts per 1 sq. square meter. If you need to select a boiler for a private house, the price of this technique can also be of considerable importance. Finally, we advise you to pay attention to the type of fuel - and purchase exactly such a boiler, the use of which will be the most profitable and less costly for you.
Gas heating equipment
General scheme of gas heating
The most widespread and efficient fuel is gas. Despite the annual growth in cost, it still remains economically viable in comparison with other types of energy carrier - wood, coal, diesel fuel, and even more so electricity. The standard equipment for heating a private house directly depends on the type of system. For a water boiler, these are: a boiler, a security group, pipelines, radiators and devices for monitoring and adjusting parameters. When using gas as the main type of fuel, the following factors must also be taken into account:
- Discussion of safe work. The boiler must be equipped with sensors for lack of draft and burner flame control;
- The diameter of the chimney must correspond to the power and type of the boiler;
- When using liquefied gas, ensure that it is stored and transported to the heating boiler.
What gas equipment for heating boilers must be purchased without fail? First, we will consider the main characteristics of the devices themselves for heating water.
According to current standards, wall-mounted gas boilers can be installed in any non-residential room - kitchen, bathroom. In this case, it is necessary to provide ventilation of the room.
Choosing a boiler
Gas boiler diagram
The principle of operation of a gas boiler is common to all models - gas is ignited in the burner, as a result of which heat energy is generated. With the help of a heat exchanger, it is transferred to water for its further transportation to heating devices - radiators and batteries.
The set of gas equipment for heating boilers directly depends on the specific model. Therefore, it is necessary to pay special attention to the choice of a heating device. Several important characteristics can be distinguished, on which the operation of the equipment in the future will depend:
- Burner type - open (air is taken from the room) or closed (air intake is carried out from the street through a coaxial chimney);
- The presence of a second DHW circuit;
- type of instalation - floor or wall;
- Gas used - natural or liquefied.To change the type of energy carrier, it is necessary to replace the nozzles;
- The presence of auxiliary equipment in the structure - expansion tank, circulation pump and safety group.
The last point is important, since the purchase of gas equipment for heating a private house, which is necessary for a complete set of the system, will depend on it. Almost all modern boiler models have the listed components. Exceptions are powerful floor models designed for heating industrial and commercial buildings.
The set of equipment for gas heating may include additional containers for collecting moisture. It is an indispensable component for condensing boilers.
What are gas tanks in gas heating
Balloon heating scheme
In the presence of the main gas, the delivery of the energy carrier to the boiler is solved simply - it is enough to connect to the main. It is much more difficult to select equipment for heating boilers if bottled or liquefied gas is used.
If the daily consumption of the energy carrier is not high, it is possible to organize gas cylinder storage. To do this, you will need to purchase special containers of 2-3 gearboxes. The storage location is a steel cabinet outside the building. It is best to purchase this gas cylinder equipment for home heating in a set.
However, this method has one significant drawback - it is necessary to constantly replenish fuel supplies. Alternatively, you can consider installing a gas holder - a gas storage tank. Usually its volume is 10-15% more than the calculated seasonal fuel consumption.
Gas holder
Unlike gas-cylinder equipment for heating a house, a gas tank is characterized by high initial costs for the purchase of a container and its installation. However, in the future, the labor intensity of heating maintenance is significantly reduced.
Filling the gas into the gas tank and cleaning it should be carried out by special companies that have an appropriate license for this type of work.
Selection of a gas heating boiler
For many of those who select a gas boiler by parameters, the cost of this technique can be very important, but not the only factor. In addition, it is worth determining its location - whether it will be wall-mounted or floor-standing. An equally significant factor in its volatility, the equipment can be autonomous or it must be connected to the mains. Finally, these models are single-circuit and double-circuit, the former provide only heating, and the latter provide heating and DHW heating. Employees will be happy to help you figure out all these subtleties.
What is needed for this?
Some idea of what equipment is used for heating a private house during its installation can be obtained from the figure below:
Components of heating a private house
It should be noted right away that this is not a complete list. Additionally, it is necessary to take into account heating devices that directly heat the room. As an example, you can give another picture, which shows such elements, as well as some piping.
Heating radiator piping
Any detail of the heating equipment shown in the figures deserves at least a brief mention in this review and, as far as possible, this will be done.
Selection of an electric heating boiler
In addition to the selection of a gas boiler for a private house by parameters, our clients are also interested in other types of these devices. For example, electric models are very popular.Such boilers must be selected according to their power indicators (this is a universal parameter for any models), the type of connection (220V or 380V), the principle of power regulation (stepwise or smooth), as well as the heating method (heating element or electrode). Each of the listed criteria can play a rather important role, therefore, we recommend that you pay special attention to all of them.
Equipment for hot water heating
Example of hot water heating
The choice of equipment for heating a house depends on the heat supply scheme. The most common is aquatic, as it has a number of unique qualities. The decisive one is the ability to install a new heating boiler without replacing other components - pipes and radiators.
All equipment for autonomous heating can be divided into two categories: mandatory and auxiliary. The former are necessary to ensure the operation of heating, and the latter are used to carry out repair and preventive measures. It is noteworthy that the components from the first group must be present in the circuit without fail, and the auxiliary ones are not. This is due to rare use. Most often they are required when carrying out preventive work before starting the system or to eliminate emergency situations.
Equipment and heating for greenhouses are no different from those for a residential building. The difference is in the relatively small size of the room.
Mandatory equipment for hot water heating
Water heating safety group
The key element of any hot water heating system is the boiler. It is necessary to heat the coolant. Each type of equipment for heating boilers depends on the type of fuel used in them.
Solid fuel models have the simplest complete set. To control the heating level, thermometers and pressure sensors are provided in their design. In modern pyrolysis models, in addition to this, fan control systems and a mechanical regulator of the flap position in the ash pan are installed.
The mandatory set of equipment for autonomous heating should include the following components:
- Expansion tank of open or closed type;
- Security group - air vent, water discharge valve;
- Thermometers and manometers;
- Circulation pump for creating systems with forced movement of hot water;
- Control devices - thermostats.
The number and type of equipment for heating boilers depends on the specific heat supply scheme. The choice is made according to the manufacturer's recommendations, based on the calculated data.
After installing the equipment for heating a private house, it is necessary to test it at the maximum thermal modes of operation of the system.
Additional equipment for water heating
Equipment for pressure testing and heating flushing
In addition to the required elements of the system, additional devices may be required. These include equipment for pressure testing of heating systems, as well as cleaning it from accumulated scale inside pipes and radiators.
The equipment for flushing the heating system is a circulation pump, in addition to which a sealed liquid container and filters are installed. The models differ in the total volume of pipes for heating radiators, which can be cleaned when the unit is connected. Particular attention must be paid to the composition of the liquid used - it may not always be compatible with plastic pipelines and aluminum radiators.
The average cost of equipment for flushing the heating system is from 52,000 rubles. and higher. Therefore, the purchase is not recommended - it is best to rent a pump or use the services of specialized companies.
When choosing equipment for pressure testing of heating systems, you should pay attention to the way to create excess pressure in the system:
- Hand pump... Convenient for crimping small lengths of highways;
- Electric pump... It can be used to quickly check the system for leaks and tight connections.
Often, equipment for pressure testing and flushing of heating systems is part of a single complex. However, the cost of such installations is quite high - they are used only when servicing large heating systems in production or commercial buildings.
All types of equipment for heating a private house must be periodically tested for operability.
Selection of a solid fuel heating boiler
Solid fuel heating boilers are no less common; many visitors to the Technodom online store want to purchase this particular type of product. When choosing them, we advise you to pay attention to the fuel used by the boiler (coal, firewood, pellets, pyrolysis boilers enjoy considerable success), the method of loading it (automatic or manual), the material of the heat exchanger, the volume of the combustion chamber, energy consumption, etc. We will also be happy to help you choose a double-circuit boiler for an indirect heating boiler.
Tips for completing the heating system
Heating system composition
Modern heat supply systems are a complex complex of several types of components and components. All equipment for heating a house must perform a specific function - maintaining a comfortable temperature level in the premises.
In practice, several selection problems can be encountered, which will entail incorrect operation of the heating supply. In order for equipment for gas heating or air heating to perform its functions, you need to know the following rules:
- A preliminary calculation of the system parameters is mandatory... Based on the data obtained, the technical and operational qualities of future heating elements are formed;
- Market monitoring - analysis of offers from various manufacturers, familiarization with customer reviews;
- Studying the wiring diagram - the equipment for autonomous heating will work normally only if the installation rules are observed.
At first glance, these are simple rules. However, they are not always guided by them, which leads to difficulties in the installation and maintenance of the system. Do not forget about the safety of the heat supply. This applies in particular to gas equipment for heating boilers. In many cases, installation should only be carried out by representatives of the management company or the manufacturer of a particular model.
When choosing system components, it is recommended to purchase goods from one manufacturer. In this way, the safety of the heating operation can be increased.
Types of heating systems
All heating systems can be classified according to a number of characteristics.
Fuel used
Depending on the type of energy carrier used, heat sources can be:
- Gas
- Solid fuel
- Liquid fuel
- Electric
- Geothermal
Installation of heating in cottages with boilers burning liquid fuel is extremely rare. Usually only when all other fuel sources are not available and shipping is too expensive.
Electric heating equipment is easy to install and very convenient to operate. But the cost of such heat is higher than when burning gas or solid fuel. Making changes to this situation, it is likely, will be able to give the use of flat Tesla induction coils, which have recently begun to appear on the Russian market.
Coolant type
By the type of heat carrier used, individual heating systems can be:
- Aquatic
- Steam
- Electrical
- Gas
- Air
In our country, the most common heating schemes using a liquid heat carrier. They are followed by approximately equal shares of electric and gas. Steam is used only in industrial enterprises, and the installation of air heating as the main one can be found only in the southern regions.
Circulation type
The movement of heated water in heating systems can be organized in two ways:
- Naturally
- Forcibly
The main advantage of the first type is complete independence from the stability of the power supply. In them, the coolant moves through the pipeline due to the ability of the liquid to rise up when heated, and fall down when cooled. But the low stability of operation, the need to increase the pipe diameters, the problematic setting of the temperature and the use of radiators with a large internal volume make the use of such heating systems unpopular.
The forced movement of the coolant is carried out due to the operation of electrically driven circulation pumps. This significantly improves reliability, comfort of use and reduces operating costs.
What is needed for heating
The list of equipment for a home heating system is quite large, but it is important to know that each element in heating that is used to heat a house plays an important role in the normal operation of the entire heating system. The list begins with the purchase of the boiler itself with all its components (burner, control system) to the purchase of heating radiators according to your taste.
The elements of equipment for the heating system are quite different, and you need to think about the question of what is needed for heating even during the design of the house.
Air heating
The choice of an air heating system in which fireplaces are used (as a rule, with a closed firebox, since open models are more decorative elements of the interior than heating devices) and stoves, is not always rational, if necessary, to heat large areas. However, for houses and cottages up to 100-150 sq. m, the capabilities of such equipment are quite enough, especially with the right approach to the distribution of air throughout the building.
The performance of standard heating stoves and fireplaces is from 5 to 12 kW, for some models it can reach 15 kW and more. Moreover, they have good decorative properties, especially in the presence of fireplace screens of various sizes and configurations.
Installation features
In the water heating systems of a private or country house, equipment is installed that runs on gas (conventional and liquefied), diesel fuel, electricity and solid fuels (including firewood, pellets, coke, peat and coal).
At the same time, electrical equipment does not require the installation of a separate complex, since it is already an autonomous system in itself.
Diesel boilers are used very rarely due to the high cost of maintenance and low environmental friendliness.
Thus, most often the project for organizing a heating system for private housing provides for the installation of gas or solid fuel boilers.
Gas boiler houses
Heating, in which gas equipment is used and a central highway is required, is the most profitable option for heating a private house. Do-it-yourself installation and operation of a system in which the same gas, but already liquefied, acts as an energy carrier, is more expensive. Although the efficiency of providing housing with heat in this case remains at a good level, due to which gas boiler houses are used more often than others.
The project of the premises for such a complex should be created subject to the following rules:
- equipment with a capacity of up to 30 kW can be installed in one of the rooms of the building.With greater productivity, it requires a separate structure;
- for a boiler room, a room is required, located on the first floor and having a volume of at least 15 cubic meters. If the boiler is installed, for example, in the kitchen of a private house, the minimum size of the room doubles;
- effective ventilation is required in the room, and the wall decoration must have a fire resistance of at least 0.75 hours (high-quality plaster or tile);
- a substrate is arranged between the boiler and the floor, protruding from the edges of the equipment by 10 cm along the entire perimeter. And the distance to the nearest pieces of furniture should be at least 0.7–1 m.
It is advisable that the installation of the boiler is carried out on a podium with a height of 0.2 m, which is poured separately from the common foundation. The floor of the room is made of non-combustible material - for example, cement screed. If the mini-complex, due to its high capacity, is located in a separate building, it should not have common walls with a residential building.
Solid fuel equipment
The installation of solid fuel boilers has become more profitable after the rise in prices for gaseous fuels and other types of hydrocarbon energy sources.
When arranging them with your own hands, it must be borne in mind that for the normal operation of the equipment, the diameters of the chimney and the boiler pipe must match. This often results in a considerable pipe height required to generate sufficient head for flue gas discharge.
The boiler room must be equipped with exhaust ventilation with an exhaust area of at least 8 sq. cm for each kW of equipment power (24 sq. cm for a boiler installed in the basement).
The layer of plaster on the walls should have a thickness of 3 cm and more. A steel sheet is laid under the boiler.
The area of a separate room must be at least 8 sq. m, and the height of the ceilings is from 2.5 m.
