Those heaters suck. I had one explode on me. I almost crapped my pants, cuz it was late at night, I was surfing reef central, like always, I heard a pop and a flash of light, then all of a sudden I see a grip of water on the floor. Luckily I was up and the GFI tripped. What sucked the most was I had just put in a bamboo floor and it ruined part of my floor.
