I have had several Rowentas, from inexpensive to really expensive. I think they are pretty much overrated.
I now use a Laura Star iron, one that my husband bought for me in Germany about ten years ago. It uses 220 volts, and gets hot VERY FAST. DH re-wired the sewing room for 220. He tells me that the 220 voltage is what makes the iron get hot VERY FAST.
This is an ironing system that is absolutely without equal. 220 is the way to go if you want FAST service !!
