I have 2 Holmes Oil Filled heaters, one in our bedroom and one in my sewing room. We have had these for years and love them. There is no exposed heating element. This is link for Target. I think we got the first one at Costo, it was a DeLongi. My SIL liked it so much when we visited her and took it with us that we gave it to her and bought another for ourselves.
