The large paraffin cold frame heater from Parasene will burn continuously for approximately 14 days on one filling, making it ideal for use over long periods of time for providing the right environment for seed growth and frost protection in larger growing structures and for localising heat in greenhouses. Made from powder coated steel it holds approximately 2.25 litres of paraffin and, as with all heaters care should be taken with positioning and use. Full operating instructions are given.
