Once a hot tub is installed, it is the responsibility of the owner to take proper care of it. One of the best things that can be done is to purchase a hot tub cover. Hot tub covers serve many purposes, but the main goal of using one of these it to keep the unit free of debris and animals when not in use. In addition to protecting the hot tub, covers help keep the costs of operating it down. An energy efficient cover can help keep the costs of operating the hot tub down by almost half, while an insufficient one can almost double a homes energy usage. Popular manufacturers of hot tub covers include America’s Spa Mart, Coverplay and The Cover Guy.
