Heating of greenhouses in winter: gas, air, electrical, biological, natural. How to heat a winter greenhouse

Thanks to the ability to maintain highthe temperature of the air in the greenhouses, our compatriots intercept and implement the overseas experience of gardening. Now the seeds germinate faster, the reproducibility of the crops turns into a multiple, and the season of active flowering of local and tropical ornamental plants has increased at times. In addition, each self-respecting land owner can make the quality, efficient and inexpensive heating of the greenhouse by himself.

How to heat a greenhouse

The question of how to heat a hotbed was actualdozens of years ago, the same remains today. The solution of this task is very important, since it allows to operate the greenhouse all year round. To date, there is a huge number of heating systems for this application. But in order to choose the most suitable among them, it is worth considering some factors:

• 
  Is there any need for heating in general?


• 
  What is the specific task of the functioning of your greenhouse?


• 
  What is the period of active use of the greenhouse structure during the year?


• 
  What is the amount of the budget allocated for the organization of the heating system of the greenhouse?


• 
  How do you personally feel about this or that type of heating a greenhouse?

Each plant has an optimal temperaturethreshold, necessary for active growth and development. Proceeding from this, it is easy to calculate how many degrees the heating system should raise the air temperature. And this indicator, as is known, also plays an important role in choosing the method of heating the greenhouse.

Types of heating greenhouses in winter

Modern heating for the winter greenhouse is provided by three categories of heating systems: natural, technical and biological.

The natural heating of greenhouses is based onuse of solar energy. This option is low-cost and completely clean in terms of its environmental friendliness. The essence of the popular greenhouse effect is the passage of sunlight through the transparent coating of the greenhouse. They heat the surface of the soil and other objects, and as a result, the air temperature rises. Due to the density of the finishing material and the reliability of the greenhouse structures, the heat remains inside without leaving the room. The disadvantage of this kind of heating is seasonality. In Russia, this method can be used in the period from late March to early October.

Biological heating of greenhouses isuse of heat released during the decomposition of organic products of vital activity of various microorganisms. Such heat, as a rule, is enough for the growing season. In the same way, air in the greenhouse is enriched with carbon dioxide necessary for plants, and the humidity level automatically rises to a more comfortable mark. Since ancient times for such heating greenhouses used horse manure. But in the winter period of time, you can not use such a system (heating). Single biological heating is not enough for the comfortable cultivation of most crops.

Technical systems are optimal for all-seasongreenhouses (including a glasshouse made of polycarbonate 5-3m). This category includes: electric heating, air heating, gas heating, stove heating with small appliances. Do not forget about reducing heat loss. Since the heating of the greenhouse design by technical systems is to some extent costly, it would not be superfluous to think about saving.

Electrical heating systems are considered the mostpopular. Professionals, amateurs and commercial figures have long appreciated such an invention. The list of devices to normalize and maintain the desired temperature level includes:

1. 
   Heaters - Portable compact heat fans;


2. 
   Convection systems and convectors - appliances with heating spirals and air supply system;


3. 
   Cable heating - a method that involves the installation of a heating cable in the ground;


4. 
   Heat pump - a system that processes natural energy into heat;


5. 
   Infrared heaters - appliances that do not heat the air, but the surface of the ground and other objects;


6. 
   Water heating - a universal system, which heats both the ground and air, depending on the installation of the structure.

Air heating, in contrast to electrical,is prepared by specialists even at the stage of construction of the greenhouse. A professional system involves the use of heating and ventilation units mounted on separate supports or supporting structures.

For the organization of gas greenhouse heatinguse gas generators, operating from a cylinder or a common network. In cases with stove heating, greenhouses are used for all kinds of furnaces and fuel in the form of firewood, coal, etc.

Heating of greenhouses with firewood

One of the cheapest ways to heat a greenhouse- use of stoves on wood. Apparatuses of different sizes and principles of operation make it possible to organize a stable maintenance of a certain temperature in the hotbed without frequent firewood bookmarks.

Often, a furnace for heatingwith own hand from available materials. For example, options with a horizontal chimney. Its design is as follows: in the waiting room, organize a brick furnace, and along the entire length of the greenhouse (directly under the shelves) a thick chimney is laid. Outgoing heat qualitatively warms the building.

Small decorative furnaces for heating with firewood

Often, beginners and experienced gardenersfarmers use small decorative furnaces for heating with firewood. Apparatuses such as Bugleran excel at keeping the right temperature in the greenhouse. With their help, the premise quickly warms up for a period of 6-8 hours from one firewood tab. That is, night hikes to the greenhouse are not needed. It is enough to lay fuel in the evening, and then - early in the morning.

Furnace Buleryan can be found in a specialized outlet, or ordered from the manufacturer through an online store. Although some farmers prefer to create heating appliances with their own hands.

Heating of greenhouses with own hands

As an alternative to "wood burning" furnaces, long-burning combustion apparatuses operating on the basis of gas generation are used. In comparison with previous types of heating, they have many advantages:

• 
  Autonomy in relation to electricity and gas;


• 
  Possibility of constant maintenance of a uniform temperature mode;


• 
  The economics associated with the low cost of solid fuels;


• 
  Possibility of operation of long-burning boilers in any climatic conditions;


• 
  Replacement of fuel in the form of quality firewood by a cheaper option - coal, dry manure, woodworking waste, briquettes, straw, husk.

In fact, no heating of the greenhouse with their own handscan not be called ideal or the most faithful. Each option takes place in individual situations with different territorial and climatic conditions. Any construction forum contains a master class for winter greenhouses and the necessary blueprints, thanks to which you can build such a greenhouse on the ground. Yutoub also offers useful videos, one of which is presented here:

Price greenhouses: you can buy these greenhouses from about 25-30 thousand rubles.
