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:
Pool surface area - The bigger the pool, the more surface area, therefore, a greater evaporation volume.
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.
Humidity - The drier the air is, the greater the evaporation rate. In very humid conditions less evaporation occurs.
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

Daisy 525TB Titanium Blue Pool Cover
"Bubble" covers, as they're commonly referred to, are ideal for non-heated pools or solar heated pools.
Series 525 UltraDome+ Titanium Blue pool covers are the premium choice for maximum heat, retention and durability. Replacing the Series 8 (500um), Series 525 is 5% thicker at 525um and comes in a variety of stylish titanium colours to match pool landscapes and garden settings. Modern and sophisticated, these covers complement contemporary pool landscapes.
UltraDome+ solar pool covers not only utilise the most advanced UltraDome™ bubble technology, they have been designed to let the maximum amount of the sun’s energy through and less out.
Its unique clear top layer lets through all the sun’s energy while its specially formulated translucent bottom layer allows maximum heat retention, warming the water and fully insulating the pool.

Sunbather Thermal Covers
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.
