The DR. INFRARED HEATER greenhouse heater is designed to tender precious plants. We understand space is very important in smaller greenhouses, therefore, our heater will take zero floor space. The big difference between conventional greenhouse heaters is efficiency. Conventional fan force heater will circulate and heat up the whole room with the majority of the heat lost through walls, floor, and ceiling. The infrared greenhouse heater will apply warmth directly to the plants with very minimal heat lost through the walls. Effectively, infrared heaters are more efficient at applying heat to plants. Our greenhouse heater can be mounted on the wall, or ceiling, or even hang down from the ceiling with the provided chains and accessories. Dr. Heater is designed with a plug-and-play thermal cord that will sense the temperature close to the plant and feedback to the heater for auto temperature control. The heater can be operated in Smart mode - auto-regulate the temperature, or manual mode - with full control by the user. All Dr. Heater products are designed in the USA and are listed by nationally recognized safety laboratories such as UL and ETL.
