Why Replace Your Cover
Canadian winters are cold, and insulating your hot tub is essential to keeping operating costs low. Using an old hot tub cover can cost you money, but when should you upgrade to a new cover? If you wonder if it might be time to upgrade your cover, here are the absolute tell-tale signs that you should put your order in now.
Hot tub covers have a foam core that traps in warm air and provides insulation from the cold. However, hot tub covers become heavy when that foam core is water-logged, and this dramatically reduces the insulation effect. While the foam core is wrapped in a plastic vapour barrier, it breaks down over time. When water seeps in, it causes rapid heat loss because water conducts heat (away from your hot tub) 30x faster than air.
Your cover is designed to sit directly on top of the hot tub shell and create a seal to help hold heat in. Over time, as covers become misshapen, water pools on the top of one or both sides.
