I don't know about the newer Clover irons but the older models, the iron had to be brought to highest temp several times before it reached max temp. Once it reached max temp then it, it would get very hot after that when turned on. DH explained it to me but I forgot most of it. I almost threw mine away, it wouldn't get hot enough, I only tried it twice. DH said to heat it up, let it cool then retry. After about four times the iron got hot and stayed hot.
