Insulation is one of the most important aspects to consider when purchasing a hot tub.
It is the part of the hot tub s design and construction that will most determine the cost of operation. Imagine two hot tubs identical in size, holding the same amount of water, located in the same backyard, used identically, but that have dramatically different operating costs. The difference is due to the method and type of insulation. No matter what type of insulation is used, as long as some form or method is employed, it will assist in reducing the operating cost of the spa. By incorporating insulation into the spa structure, the manufacturer is reducing the time it takes for the water temperature to pass from the body of water to the outside environment.
