Greenhouses are structures that allow the cultivation of plants in a controlled environment. However, temperature fluctuations can slow plant growth, especially during cold seasons, where heating systems play a key role in horticulture:
Heating systems can prevent problems such as:
Best Greenhouse Heating system
In NOVAGRIC we have a long experience in the installation and maintenance of heating systems capable of providing the ideal temperature for your crop.
After studying your farm and climatic conditions, our technical department will design a heating solution that distributes heat evenly in your greenhouse and is adapted to your needs and your level of investment.
Hot water heating
In many cases, the heating system is positioned in such a way that it provides uniform heat to all the fields and also serves as a base and rail for moving the wagons between the crop rows for tilling, moving machinery or transporting the harvest.
In other cases, it is used as a management tool in the control of transpiration and humidity, disease control, etc.
In high-power generators, three-pass flue gas systems are used with large heating surfaces and water volumes, which allow the combustion gases to be used as a source of carbon fertiliser for crops.
The system then has a dual use, and other systems such as hot water storage tanks, expansion systems, condensers or flue gas recovery units form a single unit. (Drop-down with characteristics or technical specifications)
Air heating
A hot air generator burns fuel and expels the heat together with the greenhouse air with the help of an atmospheric or pressurized burner depending on the model. The heat is then evacuated in the greenhouse with the help of a fan, usually a helical fan.
The type of air distribution can be done by flexible hose or galvanized manifold and hose. It is possible to use gas, diesel or fuel tanks to feed the heating network.
In Novagric we will study your case to install and place the generators according to the size of your farm and that you can have an adequate air flow and dart range of the fans to distribute the hot air throughout the volume of the greenhouse.
Underfloor heating
Underfloor heating is a heating system that takes advantage of the heat conduction capacity of the soil.
It consists of a network of pipes laid in a mesh along the greenhouse floor.
These pipes are filled with hot water that acts as a thermal fluid, and the heat radiates from the pipes upwards, heating both the soil, the roots of the plants, and the air in the greenhouse.
Sustainable energy sources for greenhouse heating
The future of greenhouse heating is focused on improving energy efficiency, reducing costs and carbon emissions by adopting more sustainable energy sources, such as geothermal, biomass and solar energy.
Biomass Heating
Biomass heating is a system that uses organic matter, such as agricultural waste, wood chips or pellets, to generate heat. This process involves the controlled combustion of biomass, releasing heat that is channeled through a distribution system in the greenhouse.
Heating with Solar Energy
These installations can also be complemented with solar panels to capture and store solar energy, which is then converted into heat to heat the greenhouse.
