The Benefits of Pool Covers (and Rollers)


Pool covers are a great addition to most pools as there are a number of things they help with. Keeping dirt and debris out of the pool, keeping the water in the pool by preventing evaporation and retaining heat to extend the swimming season.

Evaporation - An average heated 8 x 4m pool will lose almost 45,000 litres of water each year and up to 80,000 litres of water each year if it’s heated all year round.

The main factors that affect evaporation rates from domestic outdoor pools are:

  1. Pool surface area - The bigger the pool, the more surface area, therefore, a greater evaporation volume.

  2. The temperature of the water and air - The highest evaporation rates occur when the differences between water and air temperatures are the greatest. This may not be in the middle of a hot day when the pool is in use. At this point the water and air temperatures may be quite close. Later at night the pool water may remain warm, but the air temperature has fallen substantially - that means a greater temperature difference between the air and water - and greater evaporation.

  3. Humidity - The drier the air is, the greater the evaporation rate. In very humid conditions less evaporation occurs.

  4. Wind - The final and very significant factor for home pools is wind. A breeze of just a gentle 11 kilometres per hour can more than double the evaporation rate by removing the insulating layer of warm, moist air directly above the pool surface.


Brisbane Annual Evaporation = 1,500 mm / year
Water Loss 40sq/m Pool = 60,000 Litres*

So, how often do you top up your pool in summer?

Do you know how much water flows from your backyard hose per minute?
Of course it will vary with local water pressure, but according to the NSW Government, it is approx. 17 litres per minute.

With this in mind, as an example, an average pool in summer may take topping up for 10 minutes a day, every second day. This would use: 17 litres x 10 minutes x 15 days = 2,550 litres a month! And that’s a conservative estimate.

How much will a pool cover save me?

A Daisy pool blanket will almost completely stop evaporation - yet, when it does rain, all the water that does fall can still go into the pool, effectively ‘topping it up’.

If a pool cover is used diligently it will save up to 95% of your water evaporation

Sunbather Thermal Covers

Sunbather Thermal Pool Cover

Much thicker and more insulating, these covers are ideal for pools that are heated with a heat pump.

  • A Thermal Blanket is expected to last 3 times longer than a bubble cover, without the need to cover when not on the water to retain your warranty.

  • A Thermal Blanket is better suited to strong UV than bubble covers, as the sun doesn’t destroy it when not covered while off the pool.

  • Algae is a plant and requires sunlight to grow. A Thermal Blanket is the only cover which blocks out the sunlight, keeping algae at bay, hence reducing your chemical usage.

  • A pool can lose up to 10 degrees overnight if uncovered. Thermal Blankets have twice the insulating properties of bubble covers and save you $ in heating costs.

Sunbather's Thermal Pool Blanket has met the stringent requirements of SPASA Australia’s Climate Care Certified program as well as being certified by Smart Approved Watermark.

It’s made from high quality multi-layered, foam-based material, which is ideal for both indoor and outdoor use pools. It reduces water evaporation by up to 90% and is long lasting and will not breakdown overtime. A thermal cover will also keep your pool cleaner as debris and sunlight are kept out of the pool, this in turn reduces chemical consumption and aids in the prevention of algae and comes with a five-year warranty!

What is SPASA Climate Care Certification?
