01
Heating power
Power, measured in watts, determines how quickly the iron heats up and maintains stable temperature. Current models range from one thousand six hundred watts for entry-level units to three thousand two hundred watts for top performers, with a median at two thousand four hundred watts. High power enables immediate ironing and prevents temperature drops on thick fabrics. The site scores each iron according to its position on this scale: the higher the score, the greater the power.
Market median: 2,400 W
02
Steam boost output
Steam boost releases an intense jet of steam to tackle stubborn creases on linen, thick cotton or layered fabrics. This output, measured in grams per minute, ranges from thirty-five grams for basic models to two hundred and sixty grams for the most effective, with a median at one hundred and twenty grams. A high output reduces repeated passes and facilitates vertical steaming of hanging garments. The site score reflects this capacity: the higher it is, the more powerful the boost.
Market median: 120 g/min
03
Continuous steam output
Continuous steam accompanies each stroke of the iron and ensures smooth daily ironing. Outputs extend from twenty-five grams per minute for the most modest appliances to one hundred and ten grams for the most generous, with a median at thirty grams. A sustained output penetrates fibres better and speeds up work on all surfaces. The site assigns a score proportional to this output: the higher it is, the more abundant and effective the continuous steam.
Market median: 30 g/min
04
Tank autonomy
Water tank capacity defines ironing duration before refilling. Observed capacities range from zero point twenty-two litres for the smallest tanks to zero point forty litres for the largest, with a median at zero point twenty-seven litres. A generous tank limits interruptions, especially when ironing large quantities of laundry. The site score increases with capacity: the higher it is, the longer the autonomy.
Market median: 0.3 L
05
Soleplate and maintenance
The soleplate glides over fabrics and distributes heat: its quality affects ironing comfort. Check that it does not clog quickly and that steam vents remain clear. A descaling system or regular cleaning extends appliance lifespan. Empty the tank after each use and descale according to recommendations to preserve steam performance over time.
