Thanks for your reply! But can you give some example with using verb GET in this expression in present tense. like “I GET used to the heat”, is this even grammatically correct?

To say “I am used to the heat” is simply stating a fact. An example would be if a friend came to visit you and said, “How can you live here, it is so hot?!”. You could reply with, “I am used to the heat”. But if you say, “I got used to the heat” it them implies a story or journey, like when you first moved somewhere it was too hot but now after living there for a while you are used to it. You can also say, “I am getting used to the heat” which tells the listener that sometimes you are okay with the heat and sometimes you think it is too hot. I hope this helps:)
