Is it possible to complete the heating system by yourself? This task is feasible only under one condition - attention to detail. Each component of the heat supply has its own individual characteristics, which must be taken into account when coordinating the operation of the entire system. How to choose the right equipment for heating: gas, air, water? Let's find out the general selection criteria.
Tips for completing the heating system
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 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 - 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.
Equipment for 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
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, 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, open or closed;
- 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
In addition to the required elements of the system, additional devices may be required. These include equipment for crimping 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, 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.
Gas heating equipment
The most widespread and efficient fuel is gas. Despite the annual growth in cost, it still remains economically viable compared to 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
The principle of operation of a gas boiler is common to all models - gas is ignited in the burner, resulting in heat energy being 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
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 choose 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.
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.
Air heating equipment
The most difficult to install and operate equipment for air heating. This system is a network of channels through which hot air moves from the place of its heating to consumers.
Unlike gas equipment for heating boilers, when organizing air heat supply, more attention is paid to the air ducts - their shape, cross-section and the method of distributing hot air in the room. The comfort of living in the house will depend on these factors.
What should you pay attention to when choosing equipment for air heating?
- Air heating method... To do this, you can install a heat exchanger on a fireplace or boiler. Electric heaters are often used;
- Air duct material... The best option is rectangular steel pipes;
- Air supply system... As well as when choosing gas equipment for heating a private house, it is necessary to ensure a constant flow of fresh air to create comfortable and safe living conditions.
Considering all these difficulties, it is not recommended to choose equipment and heating for air-type greenhouses. This system has proven itself well in large homes and commercial buildings. However, for the best work efficiency, it is recommended to purchase complex climate systems that have the function of controlling the air temperature both in summer and in winter.
The determining factor when choosing equipment is the ability to adjust its operation in automatic and manual mode. This applies in particular to the safety and boiler control groups. You should also periodically check the condition of the components. For this, the heating load and the recommendations of the manufacturers of a particular heating element are taken into account.
