【Insulation Cover for Hot Tub Heat Pump】- Dimensions: 43 cm wide x 37 cm high x 53 cm. Compatible with multiple brands of hot tub heat pumps. Note: Only the cover is included; the hot tub heat pump itself is not included. For easy installation and removal, our cover is designed to be slightly larger than the heat pump itself. 【Durable Protection for Spa Heat Pump】- Our spa heat pump cover is made of durable 420D Oxford fabric with a waterproof coating. It is waterproof, UV-resistant, tear-resistant, and more. It protects your spa heat pump from water, UV rays, dirt, moisture, and other harmful substances, ensuring it always looks new and extending the unit's lifespan. 【User-Friendly】- The top zipper opens the cover for easy access to the control panel. This allows you to use the hot water pump without removing the cover. When not in use, the zipper can be closed to prevent dust and other contaminants from entering and getting dirty. 【Windproof Design】- The cover has two buckles on the side and an elastic bottom strap to ensure the cover fits snugly against the spa heat pump and can withstand harsh weather and not be blown away by the wind.
