Thermal Blanket
A thermal blanket sits over your pool to hold heat, cut evaporation, and reduce chemical loss. Use it whenever your pool is not in use to keep running costs down.
A thermal blanket is a pool cover that floats on the water surface, trapping heat and slowing evaporation between swims. It works by creating a barrier that reduces heat loss overnight and on cooler days.
For Auckland pool owners, a thermal blanket is one of the most practical ways to lower heating costs and reduce how often you need to top up chemicals and water.

A thermal blanket, sometimes called a solar blanket or bubble cover, is a lightweight pool cover designed to sit directly on the water surface when your pool is not in use. The air-bubble construction acts as insulation, slowing the rate at which heat escapes from the water overnight or during cooler weather.
## How It WorksThe blanket floats bubble-side down on the pool surface. The trapped air in each bubble provides a layer of insulation between the water and the open air. On sunny days, the cover also allows solar energy to pass through and warm the water beneath it, making it a passive heating aid as well as a heat-retention tool.
## What It ReducesEvaporation is the single biggest source of heat loss in an outdoor pool. A thermal blanket significantly reduces evaporation, which means less water lost, less chemical top-up needed, and lower heating costs over the season. For pools with a gas or heat pump heater, this can make a noticeable difference to running costs.
## When to Use ItPlace the blanket on the pool whenever it is not in use, overnight, during the working week, or over extended periods when the pool sits idle. The more consistently it is used, the greater the benefit. Remove it fully before anyone enters the water.
## Fitting and HandlingThermal blankets are sized to suit the pool shape and dimensions. A blanket that covers the full surface area performs best. Many pool owners pair their blanket with a roller reel to make removal and replacement quick and easy, particularly for larger pools.
## Local AdviceSparkling Pools has been servicing Auckland pools since 1992. If you are unsure which blanket size or thickness suits your pool, or whether a roller is worth adding, the team can advise based on your pool's dimensions and how it is used.

Thermal Blanket, Common Questions
What to know before adding a thermal blanket to your pool.
Swimming pool resurfacing is usually recommended when the interior feels rough, looks stained, starts flaking, becomes chalky or no longer responds well to regular cleaning.
A pool pump moves water through the filtration system so debris can be removed and treated water can circulate back into the pool.
Resurfacing renews the interior finish. Pool renovations can be broader, covering tile replacement, coping updates, plastering or other improvements around the pool.
Pool pump replacement may be needed if the pump is noisy, leaking, losing prime, struggling with circulation, frequently cutting out or no longer performing reliably.
Yes. Pool refurbishment is often suitable when the pool structure is still sound, but the surface, tiles or finish have become dated, worn or harder to maintain.
Yes. An energy efficient pool pump may help reduce running costs and improve efficiency, especially for pools that need regular circulation throughout the year.
Yes. Sparkling Pools provides concrete pool refurbishment and resurfacing options for concrete swimming pools, depending on the condition of the existing interior.
The right pool pump size depends on the pool volume, pipework, filter type and equipment setup. A pump should be matched to the whole system, not chosen by size alone.
Concrete pool resurfacing renews the interior of a concrete pool with a suitable finish, improving the surface, appearance and long-term usability.
A pool pump can last for several years, but lifespan depends on the model, installation quality, running hours, water conditions and how well the equipment is maintained.
