When selecting heatingthe system should pay attention to the dimensions of the room and its type, asfor different materials necessary intensity of heat will also vary.For example, polyethylene is characterized by high heat loss, so that material of a greenhouse would require more intensive heating of greenhouse compared to polycarbonate.

At arrangement of heating greenhouses, consider the size of the total installation costs of the system and its maintenance.Some heating options require significant financial investments, and their use in small greenhouses to be inappropriate.Others are simple and inexpensive to settling, but consume a lot of fuel in the process.

the rest, the owner must make his own decision, how beneficial is the use of a heating option specifically for his situation.The main thing is that the system provides uniform heat distribution across the room, does not dry the air and create optimal conditions for the development of crops.

heating greenhouses Options

Check out the main features of systems that are most commonly used to heat greenhouses.

Steam Heating

Steam heating

Steam Heating

This option should be considered if there is the possibility of connecting to the home heating greenhouses heating system.

Pipes routed from home to greenhouses in need of high-quality insulation.Reserve boiler capacity should be sufficient to ensure the required level of heating and the house itself, and greenhouses.

If the length of the pipe between the house and the greenhouse will be more than 10 m, the use of such a system should be abandoned.

is also a way of organizing autonomous steam heating.In this case the boiler is installed indoor greenhouse.The heating unit connected tubes and batteries, coolant flow is provided.As the coolant water is traditionally used.

to provide forced water circulation system typically staffed appropriate pumping equipment.

Air Heating

Air heating

Air Heating

for air heating organization used air heated in the furnace of a special boiler.This heating system is characterized by minimal cash cost of fuel, and high levels of heat output.

Air heating

Air Heating

About half an hour after starting the equipment in the greenhouse air temperature can rise to 20 degrees.An additional advantage of the system is the lack of need for any intermediate heat transfer.

Air heater is best suited for areas with a mild climate.In more severe conditions, it is recommended to apply a set of air and steam heating.

Gas heating

Gas heating

Gas heating

In this system, the heat is generated by combustion of gas.You can arrange the system as a means of connecting to the stationary summing up the gas, and by the use of fuel in the cylinders.

Gas heater

Gas heater

In operation, the system is an intensive air from the heated room, accompanied by the release of water, carbon dioxide and other wastes that are hazardous to humans and, of course, plants.In view of this, the gas heating arrangement would entail additional costs for the organization of the ventilation system.

Such heating is well suited for small-area greenhouses.If you use it on the large areas of the costs and complexity of the service can be prohibitive.

Electric heating

Electric heating

Electric heating

Modern electric heating units allow to build an efficient heating greenhouses effortlessly.

Experts recommend to give preference to the infrared lamps and heaters.

Among the main advantages of such devices should be noted that there is only heating plants and the soil in the course of their work.The air is thus not warming up.It gradually receives heat from the hot ground.This allows you to build the most efficient and economical heating system.

IR heaters

IR heaters

Modern systems are supplied with sensors and temperature controllers, which gives ample opportunity for separating the greenhouse at different heat zones and ensure the most favorable conditions for each plant group.

Furnace Heating

Furnace for greenhouses

oven greenhouse

main unit in a heating system is a solid fuel fired boiler, as a rule, with wood or coal.

most simple furnace heating system includes in its membership a solid fuel boiler and fume collection pipe coming out of the premises greenhouses into the street.Additionally, you can equip the system of pipes and radiators, which will organize the most efficient and high-quality heating.

chimney requires regular cleaning of the combustion products.

available on the market as conventional wood-burning stoves and modern boilers long burning.Such devices do not require frequent fuel tab, and spend it as efficiently as possible.

solid fuel boiler installation indoors directly to the greenhouse air drying result and the soil, resulting in grown plants can simply die.To avoid this, when installing solid fuel boiler in the greenhouse, it is necessary to equip the air humidification system.Usually it is sufficient to set a large container of water.

stove heating greenhouses is the most popular heating option.In addition, the arrangement of such a system, there is nothing difficult - to cope with the work of even the novice master.Also, solid fuel heating unconditionally wins the electric heating in terms of cost.That is why the order of organization of heating greenhouses will be considered by the example of the heating furnace.

first step. Prepare a large metal barrel.Dye its inner surface in two layers - this will provide protection against corrosion.

second step. Make a few holes in the hull.One of them you connect the chimney.Others will be used to connect the crane and the expansion tank.

third step. Cook stove from sheet metal and insert it into the prepared barrel.

fourth step. welded to the hole in the barrel of a piece of pipe to connect the chimney.The total length of the fume collection design should be at least 4-5 m.

fifth step. Replace the expansion tank barrel.There is enough capacity volume of 20-30 liters.Buck can buy or cook their own sheet metal.

sixth step. Perform wiring pipes on the premises of the greenhouse.Lay the pipe on the ground with a pitch of 120 cm. This arrangement of the heating elements will contribute to the effective heating of the soil at the location of the plant roots.

seventh stage. Install pump for forced circulation of water through the system.

boiler for greenhouse gas bottle

To work need directly cylinder gas empty coil (tube in a U letter with a thread at the ends), metal grille, stoplatch, hinges and two metal handles for doors.You should also prepare the pipe for the chimney, taking into account the length of the greenhouse, welding device with electrodes, and drill grinders, pipes and radiator heating circuit.For the front wall of the furnace require a small sheet of steel on the area.

From these simple devices going to the boiler with a water circuit for heating greenhouses villa.

Take grille, make measurements and cut it so that the resulting interval fit inside the cylinder.We catch a lattice welding.Now the oven is divided into the fuel combustion chamber (2/3 volume), and the ash pan (1/3 volume).

Step 5

We equip the chimney.Cut pipe hole in the upper rear part of the furnace.Welded pipe for the connection of the chimney.We monitor the quality of welds, otherwise traction and operation of the boiler will be broken.

chimney weld in such a way that it will be held at an angle of about 20 degrees across the greenhouse.Leaving the chimney will be through the back wall of the greenhouse, towering over the roof by 1 meter.Be sure to think through the insulation in place common greenhouse wall and chimney, so as not to fire happened.

chimney is connected to the pipe furnace, using sheets and asbestos clutch, tightening it with wire.

Step 6

To lead out the ends of the coil of metal pipes connect to the water circuit.The harness should be present expansion tank and a pump that will pump water through the pipes.

Thus, the heated water in the coil will flow into the radiator, and cooling down, re-enter the boiler.Chimney also serve as an additional source of heat.Also, a long chimney will reduce the heat loss by increasing the efficiency of the boiler factor.
