A standard domestic iron is only really designed to last for a couple of years before it needs replacing. That is, in normal use. The manufacturers would deem 'normal usage' as maybe 3-4 hrs a week. If you're likely to be ironing for longer periods of time and need a product which will stand the test of time in a commercial environment, you'd better start looking at more commercial products which provide reliability and optimum results.
