Many people particularly enjoy using their outdoor spa or hot tub during the cold winter months.
While the wintertime can be the most enjoyable time to use an outdoor spa, if you live in an area of freezing conditions, there are some things you should do to ensure the proper operation and maximum energy efficiency of your spa. The greatest danger of using your spa in the winter time is that damage will occur from water freezing in the piping system. Most portable or self-contained spas have a system designed to prevent this from happening. When the switch in in the timer mode the spa will generally heat only during a preset time throughout the day. During the rest of the day, the heating system is off and the spa can be prone to freezing.
