Poolergetic 7x7 FT Spa & Hot Tub Thermal Blanket — 84x84in Insulated Solar Bubble Cover for Heat Retention & Evaporation Reduction

Poolergetic's 7x7 FT square spa and hot tub thermal blanket is an insulated solar bubble cover designed to trap heat, cut evaporation, and keep your spa cleaner with minimal effort.

This lightweight, PE-made floating blanket fits most 7x7 foot (84 x 84 inch) square hot tubs and inflatable spas. It uses thousands of solar-trapping bubbles to warm water from sunlight, while its insulating construction reduces overnight heat loss and limits evaporation. The cover is easy to install, simple to trim for irregular pools, and helps lower energy use and maintenance time.

How does the Poolergetic thermal blanket help retain heat?

The bubble-layer design captures solar energy and forms an insulating barrier across the water surface, reducing heat loss to air. Its material slows nighttime cooling and reduces the work your heater must do to maintain temperature.

• Thousands of air-filled bubbles act like mini solar collectors.
• PE insulation reduces conductive and convective heat loss.
• Fits flat on the water surface for consistent thermal coverage.

Will this cover reduce water evaporation and save water?

Yes — the cover minimizes direct exposure of the water to wind and sun, which dramatically cuts evaporation. Less evaporation means fewer top-ups and lower water bills over time.

• Blocks up to 95% of water evaporation under typical conditions.
• Limits mineral and chemical loss from the water.
• Reduces frequency of refilling and associated treatment work.

How does the blanket help keep my spa cleaner?

By covering the surface, the Poolergetic blanket prevents leaves, dust, and other debris from entering the water. That lowers filtration and skimming workload and shortens cleaning sessions.

• Physical barrier stops large debris and airborne contaminants.
• Reduces strain on filters and chemical balancing needs.
• Easy removal facilitates quick cleanup and storage.

Is the cover easy to fit and maintain?

Yes — the blanket is lightweight, durable, and simple to trim for irregularly shaped tubs. Place the bubble side down on the water, or lay it on the tub first to mark and cut a custom fit; then rinse and store folded when not in use.

• Designed to fit most 7x7 ft square spas and inflatable pools.
• Bubble side down placement maximizes heat transfer.
• Durable PE material resists wear, easy to clean with hose and mild soap.

Who is this for: Poolergetic's 7x7 FT thermal blanket is intended for spa and hot tub owners who want an affordable, low-effort way to conserve energy, cut water loss, and reduce daily maintenance. It's particularly useful for seasonal spa users, owners of inflatable tubs, and anyone looking to lower heating costs without major equipment changes.
