Many users have found the advantages of propane heaters far outweigh the small additional running costs, as the fuel is more completely burned and does not leave an oily residue as experienced with paraffin, kerosene or diesel heaters. There is no odour, except for the few seconds during start-up and the unit runs a little more quietly since it does not need a compressor to drive the fuel to the burner. Durable paint finish. Tested and certified to CE/EN standards. Manufactured to BS EN 1596.
