Liquid propane, or LP, grills make up about 80% of the grills in the United States. They're so popular because while natural gas grills tap directly into your homes gas source used for stoves and heaters, liquid propane grills get their fuel from a propane tank that sits beneath the grill itself. The tanks are readily available at many home goods stores and are easy to change or refill. Shop our wide variety below, or check out the other BBQ grills for sale at Appliances Connection.
