Frequently Asked Questions about Heatsavr

Should I use Heatsavr If my pool is heated?

You should absolutely use Heatsavr if your pool is heated. Heatsavr will help keep the heat generated by your heater in your pool, so that you don't have so spend as much money keeping your water up to temperature.

In 3rd party trial results, the average energy savings on heated pools using Heatsavr™, the liquid solar pool cover, have been between 10% - 35%.

Should I use Heatsavr™ If my pool is indoors?

Indoor pools will see a variety of benefits from using a liquid pool cover like Heatsavr. Not only will Heatsavr help reduce the costs of energy used to keep the pool heated to your desired temperature, but it will also help control the humidity levels in your pool room.

Every pool experiences evaporation, whether indoors or outside. That evaporation causes your pool to lose heat and water, and it results in higher humidity levels, because of the water vaporizing into the surrounding air.

If you use Heatsavr to lower that rate of evaporation, you will be reducing heat loss and humidity levels at the same time!

Should I use Heatsavr If I have a commercial pool?

Commercial aquatics centers have been using liquid pool covers manufactured by Flexible Solutions since the early 1990s. They continue to use Heatsavr because of the great savings they see on their heat loss, energy bills and water consumption.

If you have a commercial swimming pool, Heatsavr can help you cut your operating costs significantly.

Can I use Heatsavr on my Spa / Hot Tub?

You can use Heatsavr on a Spa or Hot Tub, but we recommend increasing the dosage rate slightly to compensate for the much higher temperatures. The recommended daily dosage rate is 1 ounce per 50 square feet for use on a Spa or Hot Tub.

Also, if you have a specially fitted Spa cover for your spa, we recommend using it whenever possible. However, if your Spa is open for large periods of time, Heatsavr will be able to significantly reduce the heat loss, which will lower the energy required to run your heater.

Will Heatsavr affect my pool's chemistry or equipment?

Heatsavr is pH neutral, so it will not affect the chemistry within your pool. Furthermore, it only rests on the very surface of the water, so it doesn't even interact with any of your chemicals. Additionally, Heatsavr will not affect any of your pool equipment.

The molecular size of the liquid pool cover is so small it was flow right through even the best filter media on the market, and simply work its way through the circulation system until it returns to the main body of water.


It is recommended to apply daily at the end of the day. Calculate the pools surface area (L x W).

  • Pools with a skimmer: Add 0.8 ml per square metre of surface area
  • Overflow pools: Add 1 ml per square metre of surface area
  • Spas, Hot tubs, & Hydrotherapy Pools: Add 4 ml per square metre for temperatures below 34 degrees and 6 ml per square metre for temperatures 34 degrees or higher.

Additional Info

For the more technically minded – the properties of Heatsavr 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 specially tailored molecules have the following characteristics:

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