If you get a hot tub Dotsie, besure to invest in a high efficiency one. Most dealers will tell you that they do not use much electricity, but they DO! Even the high efficiency ones will make your electric bill run $50-75 dollars more a month depending on what temperature you keep it set on. Invest in a solar cover for the hottub. This will help the heater not work as hard to keep the water warm in cold weather. And from what I understand, you have to clean it often and add certain kinds of chemicals to make the heater more efficient also. My brother has one and has been complaining about his electric bill ever since. I think his hot tub is going to be history.
