A pool heater or heat pump that sits idle through the off-season is exposed to snow, ice, UV rays, and blowing debris, and a fitted cover is a simple way to protect it until you need it again. Climate Shield covers for pool heaters and heat pumps fit around existing plumbing without disconnecting anything, and their lined interior wicks moisture away from the unit. If you store a solar blanket on its solar reel, a winter cover sized for an 18 ft. or 20 ft. reel keeps the rolled blanket protected until spring. Covers for the pool itself, from winter covers to safety covers, are in our full selection of swimming pool covers.
