This ه is a letter by itself and pronounced lighter and without the use of your throat unlike ح. Also don't confuse it with ة, as it denotes femininity and pronounced multiple ways determined by the content and context of the sentence. If you want to learn how to write it's best to start in YouTube, lots and LOTS of tutors there with extensively taught videos. I suggest "Arabic Khatawaat". The female teacher is American and is very very good at her art.
