Keep the heat in, save energy and make your hot tub up to 40% more cost-effective with the Lay-Z-Spa EnergySense Thermal Hot Tub Cover. The thermal cover offers a double layer of insulation making inflatable hot tubs more energy efficient as it retains more heat and allows water to heat much quicker. Made from ultra-strong 3-ply UV resistant and water repellent Duraplus material, the same as Lay-Z-Spa hot tubs, and includes double-stitched seams making it stronger and more impermeable. The thermal cover reduces hot tub heat loss with a thick internal layer of insulating cotton and an anti-mildew treated interior.Easy to put on and easy to take off, it has safety lock clips on an adjustable strap for a tightly secured fit meaning it won’t budge, even in windy conditions, and provides a snug fit essential for heat retention. It includes a zippered door for a built-in pump and it can be removed for external pumps.
Bought this to replace a different thermal cover that had sen better days and must say, I am impressed with the durability of the cover. It has what appears to be a very robust plastic outer but time will determine how it wears. Very pleased so far and much easier to remove and put back on from the other cover I had.. Chillout.
