outdoor kitchen is in your future, you should consider a natural gas smoker. These are typically covered grills with a built in box or drawer to which wood chips for smoking are added. Natural gas as a fuel option is becoming more commonplace as consumers learn of the benefits of outdoor cooking on natural gas.
Natural gas is less expensive than liquid propane gas...that fact alone is enough to drive consumer interest. Natural gas also burns cleaner than propane does, so there's less chance of affecting the taste of your smoking meats.
Natural gas contains about half the energy of propane. One cubic foot of propane gas has the same energy content as two cubic feet of natural gas. And still, it costs more to use propane. The difference in energy content is also the reason that a propane smoker or grill can't be hooked up directly to a natural gas line.
