I worried the same thing before putting mine in. The mist is so fine that it evaporates and cools the air. If it were a sprinkler something the water would be hot. What are the temps where you live? It's around 110 degrees where I live and the misters work great.
Normal temps around here are more like 95-99 in the summer months. I am not sure how often we will be getting these 110-115 temp now that they are happening. I thought if I buried the water line the ground might cool it down as well.
