There are a large number of options for heating equipment greenhouses, each of which has its own advantages and disadvantages, as well as differently fit into the interior of the room.
Existing types of greenhouse heating and factors influencing the choice
Considering how to do a greenhouse heating with their own hands, and choosing one of the existing options, they are guided by the following factors:
- the area of the room that needs to be heated;
- which of the existing methods is applicable in the location of the greenhouse;
- how costly the organization of the chosen method is and whether it is acceptable for you - the heating system should not only be economical in terms of the necessary materials, but also not be costly when using resources for its launch and operation;
- optimal methods of heating greenhouses provide heat up from the surface of the earth;
- heating design should provide ease of operation - if possible, equip automatic systems for switching, as well as adjusting the intensity of modes;
- in terms of appearance and how important is the moment for you, how the system fits into the interior design.
Depending on the methods of heating, they can be classified as follows:
- biological, based on natural processes occurring in the remnants of food processing animals;
- natural (solar heating of greenhouses) is based on obtaining heat for the greenhouse from solar energy;
- the technical one is based on the use of technical means, supplying various utilities (heating the greenhouse with gas, using electricity) or installing the system using its own fuel (coal, firewood, etc.).
This method of heating a greenhouse has been around for a long time and its main advantages are high efficiency along with low organization costs, as well as the fact that it has virtually no effect on the internal appearance of the greenhouse and does not take up additional space. The method is based on the ongoing process of decay of food processing residues that produce a certain amount of heat, sometimes even providing sufficient heating of the greenhouse in winter. The process of organizing such a method of heating is placed in the greenhouse or greenhouse manure (most often used for these purposes horse), which is located among the beds.
Natural heating of the greenhouse (solar)
Natural heating is often used either alone or in combination with others, equipping a polycarbonate greenhouse with its own hands (the most popular material used to cover greenhouses and special facilities to create a microclimate). The essence of such heating is to create a greenhouse effect, which is formed from the sun's rays passing through the greenhouse coverings of the greenhouse, which fall on the soil and heat it.
The advantages of this method is considered to be high efficiency, good appearance, unburdened by extra structures. Among the shortcomings, it is worth noting that it is suitable either for the more southern regions, or for those who are thinking about how to heat the greenhouse in spring - in the winter, this method does not always ensure an adequate temperature level.
Technical methods of heating allow you to organize the heating of the greenhouse with your own hands in such a way that the cultivation of various crops in them can be done year round. Consider the most common methods of heating related to this method, the best projects of arrangement of which are widely available and with certain skills can be equipped with their own hands.
Heating a greenhouse with a heating cable is considered effective, but it is a rather costly method. Its essence is as follows:
- the bottom of the greenhouse is carefully leveled;
- lay on the bottom of the reinforced mesh, which poured sand;
- put a special cable over the entire area of future beds, sprinkled with sand on top;
- top must be covered with a grid so that the heating system is not damaged when digging the ground;
- a layer of fertile soil is piled on the net.
Cable heating of the soil in the greenhouse does not take up extra space and allows you to maximize and benefit from the use of the existing soil. Special devices allow you to fully automate the process by turning on and off the heating element itself at given temperatures.
Heating infrared heaters
Infrared lamps for heating greenhouses have recently been widely used as a good way to maintain the required temperature, which also provides a pleasant atmosphere and an attractive view inside the room.
Infrared heating of greenhouses is an excellent solution for those who are wondering how to heat a polycarbonate greenhouse in the spring, if there is not enough solar energy, and has such advantages:
- is economical - allows you to heat the room with minimal cost;
- when it is used, sharp drops are excluded - a soft greenhouse microclimate is created. Infrared devices heat the surface of the structure (soil in greenhouses, walls), which gradually give off heat to the plants;
- can be installed in heated rooms, depending on the desire on the ceiling or on the walls;
- control over the operation of heaters is performed automatically.
Air heating of the greenhouse consists in the installation of special devices (heat gun, heater), having heating elements and fans in their design. This method is one of the most popular due to the presence of such advantages:
- in addition in the course of the work provides air circulation in the greenhouse;
- due to its compactness, the heaters can be moved and installed in any necessary place;
- appliances fit well into the interior of the room, which must be heated;
- ensures the absence of moisture condensation process.
The disadvantages of this method are such moments:
- air heating can not provide sufficient heating of the soil in the greenhouse;
- when the devices are located close to the plants, the leaves can be dried.
Hot water heating system
This method consists in the fact that a furnace for heating a greenhouse is installed, equipped with a piping system. With their correct location, it is possible to complement the interior of the room, decorating the oven with additional elements of decor. As a heat source, mainly solid fuels are used: firewood, peat or coal. In addition, if the greenhouse is located near the house or adjacent to it, then it is possible to use a domestic boiler for heating, having drawn pipes from it. Of the advantages, it is worth noting the low cost of fuel for the furnace, and of the shortcomings is the low reliability when the required temperature regime is reached and adjusted.
In the event that a heating system is not equipped in your greenhouse or other crop growing structure, and, for example, a sharp deterioration in weather conditions is expected (night frosts, cooling), it is quite possible to use fast heating methods:
- with kerosene lamps. In this case, kerosene is installed between the rows of plants and metal plates are placed on them, which, when heated, will transfer heat to the air;
- using candles. This method is suitable only for small-sized structures and can be used for a short time - such a source of heat shines very little time;
- using warm water bottles. Filled bottles are arranged around the perimeter of the building, between the rows and maintain a quite comfortable temperature inside.
Thinking about how to heat a greenhouse, you can choose the most suitable way of heating it from among many existing options. Having stopped on any of the options, study in detail the principle of operation, as well as the subtleties of installation and installation, and then a comfortable temperature will always be maintained in your building, ensuring a favorable climate and a good harvest.
