Liquid pool covers like Heatsavr and Ecosavr are easy to use liquid solutions that form a transparent barrier on the water's surface to reduce evaporation by 15-45%, saving on energy costs while allowing the pool to be viewed clearly from all angles; they are made from biodegradable and non-toxic ingredients, can be applied automatically or manually, and pose no risks to swimmers, plumbing, or water chemistry. Heatsavr is the original patented liquid pool cover developed by Flexible Solutions over 15 years ago to provide a safe, effective way to cover pools and minimize heat and water loss.

2. Why use a Pool Cover?
Evaporation is the major source of heat loss for all swimming
pools. To minimize energy/heat loss one must cover the pool
Covering the pool is the single most effective means of
reducing energy/heat loss

3. Why use a Liquid Pool Cover?
Ease of use and installation
Inexpensive – Low capital costs and maintenance
Works 24 / 7, even when pool is in use
Safety
Allows pool to be viewed to the bottom
Avoid entrapment
Commercial liability

5. What is it made of?
The active ingredients in liquid pool covers are biodegradable organic
compounds. Extensive testing proves that the active ingredients we
have chosen do the best possible job at reducing evaporation, saving
water and energy in every pool
The carrier agent is a bio-based Ethanol which evaporates off the pool
water within minutes of being dose. Ethanol allows the active
ingredients to spread out quickly and effectively. When the carrier
agent is not an alcohol, as in some competing products, the resulting
application is a slurry or milky solution, which spreads more slowly
and may coagulate.

6. The Science
HeatsavrTM consists of
molecules that are attracted
to water at one end and
repelled by water at the
other. Each molecule
entangles with its neighbors
forming a barrier that slows
the evaporation of water

Molecules spread out at a

Sand Filters – 20 – 25 microns filtration
Cartridge Filters – 5 – 10 microns
DE Filters – 3 – 5 microns
Probes, Pumps and other equipment

14. Pool Chemistry
pH Neutral
No adverse effects on chemistry
Chlorine/Bromine and gassing off
Ozone, UV treatment and flocculants
“ In conclusion, pool water quality components common monitored by
pool operators, including: free, total and combined chlorine; water
temperature, total dissolved solids, cyanuric acid, pH, total alkalinity,
calcium hardness, saturation index, iron, copper, nitrates, phosphates
and clarity were not affected by the addition of Heatsavr. Minor
fluctuations in water chemistry that occurred during the 30-minute test
periods were more likely a consequence of normal chemical
consumption resulting from introduction of bather and environmental
wastes, and automated chemical injection.”
Alison Osinski, Ph. D.

15. Safety Data

16. Safety Tests
HeatsavrTM is accepted by the NSF
“It is my opinion that under conditions of
intended use the isopropanol component of
Heatsavr presents no health risk to the general
public…In concentrations used in Heatsavr, it is
my opinion that the proprietary ingredient
would present no health risk to the general
public.”
