That lovely site in the hilly resort you visited last winter! Fire pits, for layman is an artificial hole or pit purposefully made to contain fire. Fire pits are usually not seen in homes, but a few big ones have it. In simple words, fire pit is a camp-fire in an artificial circular pit. Fire pits are often made where there are large gatherings and where people socialize. These places can be huge family houses, jungle resorts, hill resorts where in the guests sit around it at the night or gather to mingle and enjoy the cold weather. So basically to keep the fire going, there is a need of gas line, which would keep the flame on.
