Query: Not enough heat

I iron some pretty heavy shirts and this iron just didn't cut it in the end. The heat generated was not enough to avoid wrinkles caused by the iron going over the shirt. I went back to my corded iron and saw how much better constant heat was for ironing. I really wanted to like this iron but it just didn't deliver unfortunately. Hopefully Panasonic can improve in future models.
