1000 Watt Infrared Heater works by heating the plants, not the air, so it is very energy efficient and plants love infrared heat.
Heater is sized for the 10×15 model greenhouse. Heater comes with a thermostat (Celsius), power cord, and wire hangers to attach to the ceiling of the greenhouse. We recommend you hire an electrician to wire up the power cord and thermostat.
Uses 120V and needs its own 20A circuit.
