Liquid Pool Covers

- are a very effective heat-retaining and humidity-reducing covers that are completely unique. We have installed dozens over the years

For over fifty years, scientists have known that a mono-layer (one molecule thick) spread across the surface of a liquid can dramatically reduce evaporation and energy loss

Heatsaver is a patented product developed over 16 years ago by Flexible Solutions of Canada, an AMEX quoted company which is in the forefront of evaporation control technology

Unlike a conventional pool cover which has to be removed from the pool for swimming, Heatsaver breaks apart whenever the water is sufficiently disturbed but the mono-layer reforms whenever the water becomes calm again

Consequently Heatsavr adjusts perfectly to changing activity levels in the pool throughout the day. A variable and flexible cover that automatically works whenever and wherever the pool surface is calm

Heatsavr Benefits

  • The most cost-effective solution to pool-water evaporation
  • Proven energy savings of over 50%
  • Reduces heat loss by two-thirds or more
  • Completely hassle free - just enjoy your pool
  • Dramatically extends the swim-season
  • Reduces water-loss

Liquid Pool Cover before and after

  • Extends the life of your pool-water
  • Transparent - it's much safer to be able to see all of your pool
  • No roller to clutter up the pool area
  • Harmless, non-toxic and biodegradable
  • Fits any size or shape of pool - exactly
  • Reduces humidity on indoor pools, therby reducing energy bills
  • Works with saltwater pools, Chlorine pools, etc.
  • Works with overflow and infinity pools
  • More hygienic - conventional covers require stringent and regular cleaning to avoid bacterial growth - click herehere for report

Simple and inexpensive to install

Heatsaver is filter friendly, does not affect the chemical balance (pH, sanitizer, alkalinity) of the water, will not damage vinyl liners or any other pool surfaces and is absolutely harmless to skin contact

An automatic dosing system ensures that the correct dose of liquid is added to the pool, at the same time each day

Fully programmable to suit pool size and hours of operation, it only requires a periodic check - to top up or replace the 2 litre bottle of Heatsavr liquid (Larger reservoirs are available)

Does it heat the pool?

Not exactly. A pool warms up in the Spring by storing heat energy. The water gets warmer because of the longer hours of sunshine and higher air temperatures

Meanwhile, 24 hours a day, the pool loses heat through the sides and floor (10%) and from the surface (90%), so it does not warm up very quickly. When heat-loss is reduced the pool warms faster

Heatsavr prevents about 75% of surface heat-loss - more than two-thirds of overall heat-loss

How It Works

Non-technical version

The very special, transparent and non-toxic liquid spreads, very thinly, right across the pool and stops water evaporating. It is the evaporating water that cools the pool - just like when you wear a wet tee-shirt

Heatsavr is a bio-degradable liquid, which forms a transparent monomolecular layer over the surface of a swimming pool whenever it is calm. This layer significantly reduces evaporation, which not only saves on water heating but with indoor pools can reduce the cost of humidity control and air heating requirements

An automatic dosing system ensures that the correct dose of Heatsavr is added to the pool at the same time each day

Technical version

Heatsavr is a bio-degradable liquid, which forms a transparent mono-molecular layer over the surface of a swimming pool whenever it is calm

For decades, scientists have known that a monolayer (one molecule thick) spread across the surface of a liquid dramatically reduces evaporation and energy loss

Heatsavr is a mixture of carefully chosen ingredients which automatically float to the surface. The particles of the liquid are attracted to each other and they always try to form a perfect, very thin layer over the whole pool surface

They are individually microscopic - 500 times smaller than the spaces in a high-quality DE Filter

Unlike a conventional pool cover, which has to be removed from the pool for swimming, Heatsavr breaks apart when the water is sufficiently disturbed but the monolayer reforms when the water becomes calm again

Consequently Heatsaver adjusts perfectly to changing activity levels in the pool, 24 hours a day

A variable and flexible cover that automatically works whenever and wherever the pool surface is calm

For the more technically minded – the properties of Heatsaver include a unique spreading mechanism which forms a monomolecular layer by making use of the repulsive forces generated by dissociation of ionic compounds when dissolved in water. Negative ions repel each other, as do positive ions and quickly spread the film-forming agents

Heatsavr's especially tailored molecules: -

  • Prefer their feet in water
  • Prefer their heads in the air
  • Once they are spread out, resist climbing on top of each other
  • Have side-chains (arms?) that interlock, like riot police, to keep the water molecules controlled
  • Are short lived; biodegrading to air and water within 5 days
