FAQs
What should I look for in a greenhouse space heater?
Prioritize heaters with adjustable thermostats and safety features like tip-over protection. Ensure the heater’s capacity matches your greenhouse size for efficient heating.

Look for heaters with overheat protection, waterproof or weather-resistant designs, and automatic shut-off. These features prevent accidents and ensure longevity in humid environments.
How do I determine the right heater size for my greenhouse?
Calculate the BTU needed by multiplying the greenhouse’s square footage by the desired temperature rise. Choose a heater with slightly higher capacity for colder climates.
Are ceramic heaters suitable for greenhouses?
