Heating greenhouses - a very important issue not only for the producers of agricultural products, but also for ordinary gardeners.After all, they grow not only vegetables, the price of which is growing almost every day, and some ornamental plants, flowers, herbs that are in demand in winter.
spring and summer, due to natural conditions in the greenhouse, you can grow different crops without additional heat.In autumn and winter, when and soil, and the air is cold, something very difficult to grow.Therefore it is necessary for the heating of greenhouses.
There are many different ways of heating.One of the most common and cheapest is solar heating greenhouses.It does not require the cost of purchasing equipment.All you need is just to put the greenhouse in the place where the most sunlight, and then cover it with ordinary glass.Less heat such that it can not be used in the cold season, because at night the temperature of air and soil decreases, which adversely affects the livelihoods of greenhouse plants.
most commonly used electrical equipment for greenhouses.It is the most popular heaters, species of which there are many.Here are some of them:
- convectors - devices that are equipped with heating coils.Teplitsanagrevaetsya almost uniformly, but their disadvantage - the soil warms enough.
- Heaters - Heat fans, which are easily can be moved.Compact and inexpensive.Warm air is evenly distributed.Most heaters have a thermostat, with which you can configure the necessary microclimate.His lack - dries the air.
- Cable heating - an inexpensive and highly effective way of warming.Along the perimeter of the beds lay the ground cable and tape a certain power.Important before installation - to select a temperature mode, to avoid overheating the root system.Water
- relates to electric heating, since the water is heated by electricians.It is a versatile option that can at the same time warm and the air and the ground.It also has disadvantages: the installation must be done by a qualified, high cost, it is necessary to constantly monitor the operation of the device.
also use professional system - air heating greenhouses.It is set in the assembly of the structure at the base of the foundation on the supporting structure, and that only specialists should follow.Warm air is distributed in the middle and upper part of the greenhouse space in order to avoid burns plants.
There is gas central heating with gas heaters.Their principle of operation is that the heating in the greenhouse air enters carbon dioxide and steam, that plants need.But it could be burnout air and burning oxygen.For plants, it is very dangerous.To avoid this, you have to work the ventilation system and air flow.
If the room is a small greenhouse, it is not necessarily connected to the general network of the pipeline, you can take a couple of gas cylinders, which will last a long time.
quite good and very economical option - furnace heating greenhouses.You can use different energy sources: wood, coal, gas.Minus of the system - the walls of the oven very hot.There are safer options such as heating greenhouses buleryanom.This boiler does not overheat and the system is reliable and it is easy to operate.
Installation of equipment for greenhouses, it is important to follow safety rules and follow the instructions.
