A paraffin heater is a safer way to keep a small greenhouse above freezing temperatures during those colder winter months. Allowing you to continue to grow your crops and plants all year round. This economical heating system is low cost and easy to run helping your plants to survive at an affordable cost. With the large 4.5L fuel tank capacity, one fill will burn continuously for up to 168 hours. The heater is constructed from a durable powder coated metal for rust protection. It features a twin burner and wick adjusters for variable heat settings. A heat spreader sits on top of the chimney for highly efficient heat distribution. The heater measures L 30cm x W 30cm x H 41cm. Suitable for protecting areas from frost up to 4M squared or preventing frost in larger areas. For very large greenhouses more than one heater maybe required to optimise protection. 1 Wick is included. Fuel must be purchased separately.
