Tiki torches are romantic and can add an exotic flair to any outdoor setting. Tiki torches are often made of either bamboo or cast aluminum. They range in price from approximately $200 to $400 online, depending on the style of the torch. Most tiki torches come with a pole and a torch head and are assembled by simply screwing them into place. Most tiki torches run off propane gas and can generate up to 49,000 BTU per hour. When purchasing and installing a tiki torch, keep in mind you will need to have at least 36 inches of clearance around the sides of your torch as well as a reasonable amount of clearance above the torch to ensure fire safety.
