Hot Tub Manufacturing has never been considered a GREEN industry before. That is why most Hot tub companies just manufacture hot tubs, spray fiberglass and resins, use plastics and steel without much regard for the environment, except to follow EPA guidelines. Then came the “The California Energy Commission (CEC)”. They have some of the most rigid standards in the USA and they monitor energy efficiency. They recently passed a bill called “title 20″, which sets a standard amount of allowable energy used by a portable spa/hot tub. The amount of allowable energy per the new guidelines, was not met by 65% of hot tub manufacturers who failed an independent study done by California Polytechnic State University. Softub, a 20 year old company, was the only manufacturer to pass these new guidelines without having to make any changes to its manufacturing process.
