Do you love your pool, but not the heating bill?

I’ve had my pool open early in the season and late into the fall every year since it was built. On the really cold nights it’s almost alarming to watch the steam rising off the surface of the pool. Usually at that point I have imaginary $$ signs in my head floating up toward the sky. If I had it to do over again, I would have probably opted to put in a rectangle pool with an automatic cover. Boring to look at, I know, however, the automatic cover would help to hold the heat in a little bit better than, well, nothing.

There are a couple of options if you are looking to save some of your energy bill. Here is one of my favorites! It’s quick, easy, and almost maintenance free:

Solar Fish – Liquid Solar Blanket
Flexible Solutions has designed a product that will allow you to replace your conventional solar pool blanket. The disposable plastic fish contains a special heat saver liquid that forms a transparent layer on your pool surface to hold the heat in your swimming pool. ECOSAVR is biodegradable, odorless, safe and undetectable by pool users.

The History of Ecosavr™

In 1997, Dan O’Brien, President of Flexible Solutions invented a flexible bag dispensing system that made it possible to deploy a liquid pool blanket for a whole month by simply cutting off a portion and placing the flexible container in the pool.

Mr. O’Brien filed a patent application in the U.S. for his unique system in 1998 and it was issued in 2000. It is assigned to Flexible Solutions. From 1998 until February 2004, Flexible Solutions manufactured their invention for Sunsolar Energy Technologies,  which was sold under Sunsolar’s trade-mark Tropical Fish®*.

On February 29th 2004, Flexible Solutions discontinued manufacture of Tropical Fish®* for Sunsolar Energy Technologies, and started making and selling a new and improved version of the invention, under Flexible Solutions’ own brand, Ecosavr™. The name Ecosavr™ was chosen as being appropriate for the product’s purpose – Eco for Ecologically friendly and savr for the water, energy and time it saves for the pool owner.

The liquid solar cover contained in Ecosavr™ is Heatsavr™, Flexible Solutions’ commercial liquid pool cover. Heatsavr has been on the market for 16 years and led directly to the invention of Ecosavr in 1998. The two products have 24 years of combined market experience. Flexible Solutions is the only liquid blanket manufacturer with any published safety and efficacy data.  Flexible Solutions, Heatsavr and Ecosavr are the World Leaders for liquid blankets on indoor pools and liquid solar covers for outdoor pools.

New and Improved Ecosavr™ is a Liquid solar cover for swimming pools: an alternative to conventional solar covers.

Evaporation accounts for up to 7/8 of heat loss from a swimming pool. A single Ecosavr™ contains liquid which automatically floats to the surface of the pool and acts as an evaporation inhibitor, much as a conventional solar blanket performs, except a lot easier to use.

Our key ingredient is a non-toxic chemical called Heatsavr; it’s been in use since 1991 and has a proven track record commercially. We packaged it to facilitate its application for the residential pool owner. Heatsavr™ is filter friendly, does not affect the chemical balance (PH, chlorine, alkalinity) of the water, will not damage vinyl liners or any other pool surfaces, and is absolutely harmless to skin contact.

How does it work?

Simply snip the fin where indicated and toss “Eco” in your pool. Ecosavr™ submerges to the bottom of the pool and as the pressure increases, the liquid escapes, rises, and forms an invisible layer on the surface of the water. It is 60% as effective as a conventional solar cover but 100% less trouble. It works 24 hours a day, even while people are swimming. Ecosavr™ will last for approximately 1 month. Then all you have to do is retrieve “Eco” and toss a new one in.
