Many users have found the advantages of propane heaters far outweigh the small additional running costs. The fuel is more completely burned & does not leave an oily residue as experienced with paraffin heaters. There is no odour except for the few seconds during start-up & 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 & features a direct gas head assembly. Features safety solenoid preventing the unit from leaking gas without first being electrically started. Supplied with an approved propane gas regulator & hose. Tested & certified to CE/EN standards by D V. GW. Manufactured to BS EN 416.
