Daisy 250B Blue Solar Pool Cover per M2

From the point of view of heating efficiency, no. It will heat effectively even if the pool is not totally covered, however, it will allow dirt and debris into the pool. An edge along a step or an uncovered area will provide a point at which the wind can start to worry the cover and may eventually lift it off the pool.

Provided it is properly fitted, it will not. The effect of the bubbles going down in the water creates more surface area in contact with the water than the flat pool area. Therefore the surface tension is quite high. Further, provided the edges of the cover do not rise above the coping, the effect of any wind is to create a downward pressure which pushes the cover onto the water.

If the cover edge rises above the coping because it has been cut too large, or winter rain has raised the pool water level and hence the cover, then the wind can get under the cover and send it flying into your favourite rose bush (or similar).

A Daisy pool cover allows the sun’s warmth to pass through into the water. Just like a garden hot house. Water is an excellent absorber of the sun’s heat. All water is heated by the sun and is retained in the pool water by the pool cover as it prevents the heat from escaping.

A Daisy pool cover prevents evaporation – a process which turns water to gas and dissipates into the atmosphere like a kettle boiling dry. The amount of water loss depends on the surface area of your pool, the temperature of the water and air, humidity and wind. A cover protects the water from these main conditions.

UltraDomeTM bubble technology is the heart of our Daisy pool cover structure. The UltraDomeTM bubble profile results in a total insulating air layer to the majority of the bubble depth. The air in the bubble and the air trapped between the top layer of the cover and the water effectively form a thick layer of insulation across the entire cover area.

Thermal resistance (R) is a measure of insulation effectiveness. A Daisy 525 micron pool cover achieves a high rating of 0.067m2 K.

1. Measuring your pool is simply a matter of measuring the maximum water level width (W) and length (L) of the main body of water. See video below
2. Using a tape measure, measure the length (L) and width (W) of your pool
3. If your pool has steps, measure the step area separately (see video)
4. If you have a uniquely shaped pool, treat it as rectangular (see video)

1. Lay the cover bubble side to the water.
2. Flatten out all air bubbles so that the cover sits
   relatively flat on the water.
3. Using your pool as a template, take a pair of ordinary
   household scissors (the sharper the better!), and with
   someone holding the cover in position, cut the edge
   of the cover so that it sits flat on the water with 50–
   75mm rising up the side of the pool - not necessary
   to the top edge of the pool.
   If preferred, you can:
   a) Cut the cover back to waterline however wait two to
   three weeks after initial cut for it to settle down.
   b) Cut two vertical slits in the cover upturn, either side
   of your skimmer box, fold the flap you have created
   into the skimmer box, therefore allowing you to hose
   debris off the top of the cover into the skimmer box.
   Your Daisy cover is delivered with an ample margin
   for trim. In some cases the excess is sufficient for
   secondary use and left for you to use as you see fit.
