Greenhouse Heating System
Greenhouse heating systems are generally divided into hydronic boiler heating system, electric fan and ground source heat pump heating.

Hydronic boiler heating is more balanced, after the boiler stop heating, the hot water retained in the heating pipe can continue to heat to the greenhouse. The temperature in the greenhouse will not dramatic change. It is a commonly used heating method.

Electric heating machine is heating the heater to heat the greenhouse.

The ground source heat pump is a device that use the heat from the shallow layer of the earth, provide heating and refrigerant for the buildings. It has drawn great attention around the world for apparently saving energy and meeting environmental protection requirement.
