This heater is Amazing! Quiet and Powerful I first used it on my sun porch when my other heater died. It's almost winter here, so all my other heater did was keep the chill of my porch. I put the Vortex heater on my porch and set it to 80 and within 30 minutes , it was a very warm 80 degrees on my porch. I love it , because now i can put my tropical plants back out there where they can get sun. Before with all the other heater i used it would never warm up enough keep them out there. The Awesome thing about the Vortex too, is that if my 3 year old happens to bump it and knock it over, it immediately shuts off, and even after running all day it is still safe to touch!!! I love how you can change it to the exact temperature that you want . This is definitely the best heater I have ever owned!
