The Sancell range of Sancell Pool Covers will reduce your heat loss by up to 75% simply by reducing evaporative water loss. Regardless of a pool’s heating system – electric, gas or solar – evaporating water uses tremendous amounts of energy.
So for even a small amount of water loss through evaporation, your pool’s temperature can drop significantly. Regaining lost heat can add unnecessarily to your heating bills. By conserving your pool’s heat with a Solar Pool Cover you’ll significantly cut your heating bill. It’s that simple.
Evaporation losses are highest when the pool is left uncovered during swimming sessions. As well as water loss, evaporation is also the biggest cause of energy losses in heated pools.
Outdoor pools gain heat from the sun, absorbing 75-85% of the solar energy striking the pool surface. This is an important contribution to the pool heating needs.
How does the Sancell Pool Cover keep your pool heated?
Our Solar Pool Blanket is similar to bubble packaging material except that it’s a thicker and a higher grade of plastic with UV inhibitors and stabilisers. Its bubble design maximises the efficiency of energy received from the sun, thereby reducing pool heating and maintenance costs and extending the swimming season by as much as three months.
It manages to do this in two significant ways: reducing evaporative water loss and improving the absorption and retention of solar heat.

An outdoor pool gains heat from the sun’s radiation and looses heat through water evaporation and convection. A solar pool blanket maximises absorption of short wave energy from the sun and will even raise the temperature of your pool by up to 8°C. The static air trapped in the bubbles then acts as a thermal insulator and reduces the overnight loss, so heat loss is minimal. The Sancell Solar Pool Blanket simply makes the most of the sun’s energy to save money.
Example: If we take a heated, uncovered 50 square meter pool in Sydney for the swimming season October to March the energy input to just compensate for evaporation would be 56,400 kWh and if the pool was heated by electricity this would produce over 53 tones of greenhouse gas. Using a pool cover would reduce this by 75%

Or to put simply, the energy required to compensate for evaporation on a 50 square meter pool in Sydney is equivalent to running non stop 100/100 watt light globes for the entire swimming season. This produces just over 12 kg of greenhouse gas. |
