EnergyGuard swimming pool cover

Inhibits Algae Growth

The opaque EnergyGuard material blocks light from entering the water stopping photosynthesis and hence growth of algal microscopic plant life, offering the pool owner several distinct advantages:

• Save money by using up to 70% less pool chemicals
• Reduce electricity usage and costs by cutting filtration/pump time by up to 50%
• Reduce filter blockages
• Lower the risk of eye, ear, skin and gut infections
• Avoid slippery surfaces
• Improve the aesthetics of the water
• Save money and time preparing a pool after the winter period

Winter cover inhibits algae growth

Research and tests

Even without chemical treatment, experiments proved that the EnergyGuard swimming pool cover inhibits algae growth.

The testing ran on two swimming pools for ten days, where one pool had a standard solar gain cover and the other an EnergyGuard cover. Both pools had simulated use, with no chemical treatment and no filtration.

The pool with the standard solar gain cover soon went green due to algae growth, whereas the pool with the EnergyGuard cover showed no algae growth.

This test was continued for a further two months and the pool with the EnergyGuard cover still remained free of algae for the duration.

GeoBubble technology

The EnergyGuard material available with GeoBubble technology which through its unique and patented shape increases the expected life of the product by improving its endurance against the harsh swimming pool environment with Ultra Violet light and chemical attack.

How can this save money?

An EnergyGuard cover will save money by reducing water, heating, electricity and chemical costs and can pay for itself in less than a year.

Reduce Filtration/Pump Time by up to 50%

By inhibiting algae growth filtration time can be cut by up to 50% greatly reducing your electricity usage. Filtration will still be required to circulate the water and remove impurities from the pool, but calculated on regular pool use a 50% reduction is achievable. If the pool is used heavily more filtration time will be needed.

Reduce Chemical Consumption by up to 70%

Chemical usage can be reduced as the EnergyGuard cover inhibits algae growth and eliminates water evaporation resulting in cost savings:

• Because algae growth will be inhibited by physical means by use of the EnergyGuard swimming pool cover rather than chemical means, this will result in the use of less chlorine.

• About 90% of chlorine consumed by outdoor pools is lost due to photolysis reaction which the cover also reduces.

• Additional cost savings will be made by using less pH plus/pH minus to correct any pH imbalance caused by algae.

• Chemical consumption will also be reduced through the elimination of evaporation of the water in which the chemicals are contained.

Research in collaboration with UK universities showed that by using an EnergyGuard swimming pool cover on an average sized UK pool, 4m x 8m, up to 70% could be saved in chemical consumption, which equates to up to 11kg of chlorine!

Reduce Energy Consumption by over 60%

Pool heating costs can be reduced as the EnergyGuard cover will eliminate evaporation and greatly reduce heat radiation.

Heat retention tests carried out in collaboration with two UK Universities showed energy savings of over 60%. This applied to oil, gas, electric heater or heat pump usage. Where solar heating is used, it is possible to invest in up to half the amount of panels normally required for a pool without a cover.

By using an EnergyGuard swimming pool cover on an average sized UK pool, 4m x 8m, that uses a modern heat pump, you could save up to 5000 kWh of electric every year!

Reduce Energy Costs

Eliminate Water Evaporation by 98% +

Using a swimming pool cover helps to save precious natural resources by reducing water consumption. By minimising water evaporation, by over 98%, you will also save considerably on your water costs.

Research carried out in collaboration with two UK Universities showed that in the UK an average sized pool of 4m x 8m the evaporation loss is approximately 32,000 litres of water per year. This could provide you with approximately 400 baths! This figure is reserved and will be considerably higher for hotter climates and windy conditions.

Eliminate Water Evaporation

Absorb the Sun’s Energy

We know that the colour black absorbs the sun’s heat in a very efficient way. Research and scientific tests have resulted in the development of an opaque grey colour that has similar heat absorbing characteristics.

On your pool the sun’s heat will warm the grey top surface of the EnergyGuard swimming pool cover and this energy is absorbed and transferred into the water directly under the cover increasing pool temperatures by up to 4 degrees celcius.

The use of a swimming pool cover will also help to retain this heat within the pool.

Absorb the sun's energy

Reduce Debris

Leaves, dirt, insects, bird droppings and other debris are not only unsightly in a swimming pool but also provide nutrients for algae and bacteria to feed on.

When the pool is covered these contaminants will be kept out of the water, greatly improving the quality and appearance of the water, plus helping to reduce chemical consumption.

The EnergyGuard cover can be used all year and tests proved that the EnergyGuard material has many benefits as a winter swimming pool cover.

From October 2008 through to April 2009 a swimming pool was covered with an EnergyGuard cover plus a woven mesh debris cover, with no use of winter pool chemicals.

After the 6 month period the water was clear of algae. By not having to filter, backwash and vacuum the pool, you can save the hours of time normally spent preparing the pool, as well as saving money on chemicals and electricity usage.

Benefits to the environment as well as saving money

An EnergyGuard cover will greatly reduce the carbon footprint of your pool by reducing the amount of energy needed to heat and filter your pool water. It also conserves water and, at the end of its life, all of our covers are 100% recyclable (Grade 4 LDPE recycling).


The EnergyGuard cover has a 6 year pro rata warranty. Please note that the length of the warranty may vary in some countries.

If you want to benefit more from solar energy, see our Sol+Guard™ cover, the best solar heating bubble cover available; increasing pool temperatures by up to 8°C.

If you want to reduce your pool temperature rather than benefit from solar energy gain, ask about our CoolGuard™ cover, the optimum cover for reducing water temperatures by up to 15%.
