You gotta try these

Waxmelts.

Some people have never heard of these, such a shame! Waxmelts are a great way to enjoy a burst of fragrance in your home. A waxburner and a tealight are all you need for a great scent throughout your room. You just break 1 little block and place it on the burner. When the scent wears off, you take off the wax and put a new block on the burner. The wax doesn't run out. You might come across smaller burners which are meant to be used for oils. They will work burning wax, but the scent will come off quicker. So, better use a higher burner, especially designed for waxmelts. Also, don't use large tealights, they'll burn to hot. You will find burners and tealights in the "additional products" section of this website.
