Many users have found the advantages of propane heaters far outweigh the small additional running costs. The fuel is more completely burned and does not leave an oily residue as experienced with paraffin heaters. There is no odour, except for the few seconds during start-up and the units run a little more quietly since they do not need a compressor to drive the fuel to the burner. Durable paint finish. Fan assisted, fitted with a piezoelectric ignition system for trouble-free starting and features a direct gas head assembly. Features safety solenoid preventing the unit from leaking gas without first being electrically started. Front foot offers height adjustment allowing the heat to disperse at different angles. Supplied with an approved propane gas regulator and hose. Tested and certified to CE/EN standards by DVGW. Manufactured to BS EN 416.Specifications:Output: 19.8-28.4kWOutput: 68,000-97,000Btu/hrAirflow: 400cfmFuel Consumption: 1.47-2.1kg/hrSupply: 230VLength: 638mmWidth: 220mmH
