What do radiation heaters primarily do in a greenhouse setting?

Radiation heaters primarily warm surfaces rather than the air in a greenhouse setting. These heaters operate by emitting infrared radiation, which directly heats objects and surfaces in their line of sight, such as plants, soil, and other materials located within the greenhouse. As the surfaces absorb the heat, they gradually release it back into the surrounding air, leading to a more efficient warming effect without the need to heat all the air in the space.

This method of heating is advantageous in greenhouses as it can help maintain a stable temperature around plants, promoting better growth and reducing the chance of temperature fluctuations that could stress the plants. By focusing on warming solid surfaces, radiation heaters can create a more comfortable environment for plants while minimizing energy consumption, making them an effective choice for greenhouse heating.
