Yes it does, there is a bulb that melts the wax. Much better and safer than a candle. You can put it on a timer so you come home each day to a nice smelling home.
Nice auction. A trick to get the wax out...put just the top part into the freezer and wait either a few hours or overnight (that's what I do) and when you pull it out of the freezer the wax will either just fall out or just tap it and it should come out:)
