Here's a winter tip:  Don't use your outdoor hot tub in the middle of a blizzard!  First of all, this is just plain stupid! Second of all, if I pay a couple of grand for an outdoor hot tub you had better believe that I am not going to do anything to cause it to break down which using it in the middle of a blizzard would certainly do!  If it did break down i'd be on the phone lickety-split hiring the best power supply repair known to man!  Third of all, there is such a thing called an indoor bath tub which really can be just as effective, so use some common sense and don't use your outdoor hot tub in the middle of a blizzard!
