The Warmlite WL43003YW is a white 7-fin oil filled radiator with a maximum 1500W output for portable supplementary heating. It provides three selectable settings of 600W, 900W and 1500W plus an adjustable thermostat, allowing the level of heat to be matched to changing conditions. A built-in 24-hour timer adds useful scheduling, so the radiator can be set to switch on and off around a daily routine.

Easy-glide castor wheels make the radiator more convenient to move between rooms, while the front switch controls and power indicator keep operation clear. Warmlite specifies overheat protection and a tip-over switch, designed to turn the unit off if it becomes too hot or is knocked over. For users comparing Warmlite's oil-filled models, this version prioritises a smaller 1500W, seven-fin format while retaining thermostat control, scheduling and portability.
