Greenhouses heat in a variety of ways. Heating method depends on the size of the greenhouse, the climate, and also the budget. Here are some of the most common heating methods:

Passive Solar Heating: This is the most basic form of heating. It relies on the sun’s energy to warm the greenhouse. Almost all greenhouses are typically designed with transparent materials (such as glass or plastic), that allow sunlight to enter and warm the interior. As a result, the heat will trapped inside the greenhouse and keep it warmer than the outside environment.

Active Solar Heating: This type of heating system uses solar collectors to capture the sun’s energy and convert it into heat. The heat is then used to warm the greenhouse, either directly or indirectly. Good to know that, active solar heating systems can be more expensive to install than passive solar heating systems. But they can be more effective at heating the greenhouse, especially in colder climates.

Geothermal Heating: This type of heating system uses the earth’s natural heat to warm the greenhouse. Geothermal heating systems can be very efficient, but they can also be expensive to install.

Electric Heating: Electric heaters are widely using for heating greenhouses. However, they are expensive to operate, especially in larger greenhouses.

Gas Heating: Now a day, many greenhouses using gas heaters. Simply because it is more efficient than electric heaters. However, initial cost of installation for gas heaters are more expensive compare to electric heaters.
