Heating for Winter Greenhouses from Polycarbonate

Today, many summer houses have greenhouses, in which they yearly grow various fruits and vegetables, which allows them not only to have access to fresh products constantly, but also to make money on it. But in the winter season, whatever the greenhouse, it needs heating. And today in our article we will tell about the heating of such buildings made of polycarbonate.

Design features

It should be said that whatever greenhouse, they all have about the same principle of operation. But still, such buildings have a number of features that must necessarily be under construction. The greenhouse of polycarbonate is the construction of a stationary type, and therefore needs two things:

  • good and durable frame;
  • really durable and well-made foundation.

    If it comes to year-round greenhouse, it cannot be without capital foundation. The foundation from the tree is not suitable here, because it must be changed periodically. It is best to make a foundation for such a building from brick, blocks, or concrete.

    Ribbon foundation is usually created throughout the perimeter of the structure, it is pretty simple, and its value is small.

    It is also necessary to take into account the features of the frame. The fact is that the exploitation of the described structure in winter involves the fact of the presence of snow. Its accumulation on the roof of the greenhouse leads to an increase in loads on the frame base, which can cause the gradual destruction of the greenhouse or the failure of it. For this reason, the frame must create from metal or wood.

    Ways and species

    If the greenhouse is insulated correctly, then you can choose one of the types of heating. During the choice of equipment, you need to know which heat lifter has your greenhouse. Calculation of heat loss is possible to easily request from specialists. If we talk about the most common methods of heating, then there are options:

    • based on water;
    • air;
    • infrared;

    • chimney;
    • electric;
    • solar.

    The most familiar is water heating. When installing radiators and registers from such a system, it will be a bit, because the warm air will be assembled, and at the bottom, where all plants are located, it will be cold. Yes, and it will be necessary to solve the problem of soil heating. To solve it, you can create a combined heating, which is considered traditional – when part of the coolant goes to radiators, and the second – in the pipes from which a warm floor is made.

    If desired, the coolant after exiting radiators can be administered in pipes that will be located under pallets or directly on the beds. In this way, heated will be heated.

    Another rather common type of heating will be air. True, he has a minus – the air dries very strongly, which creates the need for constant humidation. In addition, warming up in such a system will also be uneven – at the top of the air will be the warmest, and at the bottom – the coldest. Here you also need to provide a ventilation system.

    An interesting solution for greenhouses can be adaptations, which are based on the principle of infrared radiation. They will heat no air as mentioned above options, and the soil and plants themselves, from which the air will be warm. Here the principle of exposure to ordinary sunlight is based on. Under these conditions, the plants will develop significantly better, and the leaves will not dry, which can be observed when using the above options.

    In addition, it can be drunk and land. To do this, in the market you can find special carboxyry wraps that allocate heat in the so-called infrared range, film options work in the same way as lamps of this type.

    In addition, the greenhouse can be heated with sunlight. It usually happens, since the greenhouse walls are made from materials that transmit light. In the afternoon, heating occurs, and at night – cooling. But it should be said that early spring, in autumn time and winter sunny day is not so great, and the sun stands low by the horizon. To increase the efficiency of such heating, you can make a bonus of the construction of south, which will help the sunshine better to illuminate and heat the greenhouse space.

    You can also mount so-called thermal batteries in the greenhouse – Water barrels that need to paint black. Thus, during the day, water in tanks will be heated, and at night there will be a return of heat.

    Can be installed in polycarbonate greenhouses also electric heating. This option is easily implemented in several ways:

    • using a heating cable that is laid in the ground;
    • application of convectors or electrical heaters;
    • with the help of lamps;
    • Thanks to the electric boiler.

    Each of the proposed methods has its own features of the installation, but it is believed that this type of heating is one of the most effective.

    Another pretty premium heating is a furnace. It makes it possible to carry out the heating of air masses to the required temperature in all weather conditions. The main thing in this case is to heat the furnace to be commensurate with the volume of greenhouse. As a rule, the furnace is installed in this case in the coldest area – at the northern wall.

    You can use various furnaces – stone, bourgeities, buleries. The choice depends on the preferences of the greenhouse owner. Air distribution in this case can be carried out in various ways:

    • natural way;
    • using fans;
    • Thanks to air ducts.

    Typically, fuel is the wood of various types. Options more than enough.

    Types of IR heating

    One of the most effective methods of heating for the greenhouse are IR heaters. Such a system has already managed to establish itself as a high quality and very effective heating option that does not require serious costs for mounting and installation. When choosing this type of heaters, two factors must be taken into account:

    • air humidity level (is a particularly relevant factor);
    • Structural features of the greenhouse itself.

      Existing infrared heaters can be divided into several categories:

      • Gas emitters that produce not only heat, but also carbon dioxide;
      • Long-wave heaters having an open thermal heating element or an aluminum plate that provide only heat in the room;
      • short-wave electrical infrared models that also provide building heat.

      The peculiarity of such heaters is that infrared radiation is directed not to heat heating, but directly to heating plants, soil, as well as plants.

      If we talk about the principle of operation of such a heater, it is pretty simple. Its design is infrared ceramic emitters, which are placed in a frame made of mirror-polished steel. They simply reproduce rays that create imitation of light and heat of the Sun. Similar rays allow subjects, walls, plants, absorb heat, from which air heats up.

      Another important characteristic of such devices is that their rays cover the maximum area, if you move them further from the floor. Naturally, the temperature of such a surface will decrease.

      In addition to the mentioned effect, which is similar to a sunny, this type of heaters have other advantages:

      • Economy in use of energy. If you correctly install them, you can save up to forty percent of electrical energy.
      • Practicality. In the presence of a pair-troika of such heaters, it is possible to organize a number of zones in a greenhouse, where you can set the necessary temperature on any plot.

      • Clear Distribution of warm air masses. The uneven heat distribution is excluded, which can be observed in a large number of ordinary heaters, when warm air masses go up, and less warm remain at the bottom. For plants and land – it is minus. In this case, it is the subjects that are heated and from them – air.
      • When using such a heater completely Ceremonies are excluded. If you have this type of heaters next to window openings, you can compensate for thermal losses without the formation of any air movement.

        In addition, there are also infrared heaters in the form of a film, allowing to heat even soil. Therefore, such a category can be called the most effective.

        The possibilities of the heated greenhouse

        Suppose that the greenhouse will be heated, but it will not be located any additional lighting. With such a situation, it is the light, and not heat will become the most important criterion in the selection of cultures, as well as their time to germination. For example, in winter, when the duration of the day is small, there are freezing, and a lot of cloudy days, growing something even with the help of heating will be very difficult.

        So that vegetables grew actively, they need no less than twelve, or even fourteen hours of lighting. Such conditions begin to develop somewhere after March 15, and therefore at about this time it is necessary to start sowing.

        And since April, heating the greenhouse, you can prepare for the collection of the first harvest. As a rule, we are talking about Luke, parsley, dill, redish, sheet cabbage and salads. When all this is grown, you can land the seedlings of tomatoes, and then cucumbers.

        It should be said that a greenhouse that is heated, but does not have lighting, it can start working about a month earlier than the usual greenhouse. Regarding plants that are suitable for plants will be when the soil temperature is about 6-8 degrees above zero, and all freezing will stop. If you have the opportunity to constantly seek such a temperature of the soil, then year-round vegetables and fruits are provided to you. It is for this reason that it is important not only to pull the air, but also to warm the land. You can get exactly the result in three ways:

        • Warm soil biofuels and make the so-called warm beds. Under the 30-35-centimeter layer of the soil lay a layer of organic material, which decomposes during heat isolating and warms the place where the roots of the plants are located. To create such a layer, food waste, dry leaves or fresh manure can be seated.

        • Heated greenhouse underground pipeline. True, in this case, it is necessary to envisage a timely watering, since this method is strongly dried.
        • Warm soil IR heaters. The way although natural, but the costs will be serious here, because electricity consumption occurs.

        How to make himself?

          You can make your own heating heat heating. An excellent example can serve infrared heating, as the simplest and most effective. When calculating the equipment for heating, polycarbonate greenhouse should be considered its area. To create favorable conditions for germination of various crops, the power of 200 watts per square meter is necessary.

          Therefore, having the area is multiplied by the necessary heating power. As a result, you will learn the total power on which you should navigate when acquiring infrared heaters.

          Before installing such heaters, pay attention to the following nuances:

          • Installing such a heater must be carried out at an altitude of at least one meter.
          • The further the heater is from the floor, the topics covered increases, and the temperature – decreases.
          • The distance between the heater and plants is always better to keep constant. As the plants grow, the position of the heaters may be adjusted.

          • The heaters of this type are best to mount around the perimeter of the greenhouse, closer to the walls, since they are the most cold places such a building.
          • Between heaters should withstand the distance of about one and a half meters.
          • To effectively warm this building, you should have several heaters. It all depends on the actual size of the construction of the temperature, distances, heights and arrangement of heaters.

            If for heating winter greenhouses you do not want to use this type heaters, you can find other options. The easiest option will be, for example, the installation of burzhuyki. In this case, it is necessary to take into account only the area of ​​the greenhouse, as well as the desired temperature.

            Be sure to calculate how cost it is economically profitable.

            Tips and recommendations

            The first moment that must be noted is – advance accounting of available funds for the purchase of the desired system. The fact is that if in the process of its creation it turns out that you do not have enough money, the reworking the greenhouse will cost you significantly more expensive.

            Still need to immediately clearly and clearly understand what the area of ​​your greenhouse, And which stable temperature you want to achieve in it. In addition, you should take into account the fact that you are going to grow, and what conditions for these plants are necessary. All this is very important that you can achieve the maximum positive effect from the heating of your greenhouse.

            In addition, before choosing a heating system, it is necessary to calculate how much its use will be economically beneficial and cost-effective. This will also achieve the maximum effect and get a really good harvest.

            Create heating for winter greenhouses from polycarbonate is possible with their own hands. The main thing is to have a good theoretical basis and carry out in advance all the necessary calculations to calculate the economic feasibility of one or a lot of heating. Also be sure to take into account all the features of working with a second or another heating system to achieve maximum return and efficiency.

            If everything is done correctly, then you can yearnogodically enjoy fresh and high-quality fruits and vegetables grown personally.
