How it Works

Overview

For over fifty years, scientists have known that a monolayer (one molecule thick) spread across the surface of a liquid can dramatically reduce evaporation and energy loss. Many companies attempted to develop a technology, but until Flexible Solutions developed their patented Heatsavr, which they first introduced to the North American market over 12 years ago, no other company had been able to make a monolayer spread reliably and inexpensively or to regroup effectively after the water had been disturbed.

In non-technical terms Heatsavr is a mixture of carefully chosen ingredients which are lighter than water and which automatically float to the surface. The particles of the liquid are attracted to each other so that they always try to form a perfect very thin layer over the whole pool surface. They are individually so small that they are 500 times smaller than the spaces in a super high quality filter.

Unlike a conventional pool cover which has to be removed from the pool for swimming, Heatsavr breaks apart whenever the water is sufficiently disturbed but the monolayer 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.

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

Heatsavr Dosing

Heatsavr has to be added to the pool water on a daily basis to maintain its effectiveness. This is because Heatsavr biodegrades - it has what is called a 2 day half life - which means that in 2 days 50% of it has biodegraded.

The standard dose rate for pools maintained at normal swimming temperatures is between 0.8 and 1 ml per m2. However, Heatsavr bio-degrade faster at higher temperatures so for spas and higher temperature hydrotherapy pools the optimum dose rate may increased up to 4 ml per m2.

Heatsavr Automatic Dosing System

Easy and inexpensive to install the Heatsavr automatic dosing system provides a reliable and accurate method of ensuring that the pool benefits from the maximum energy savings possible. Fully programmable to suit pool size and hours of operation, it only requires a weekly reservoir check with top up when necessary. It ensures that the correct dose is added to the pool regularly and at the same time.

Commercial system

3 dosing pumps all fed from the same 25 litre day tank - serving indoor pool, outdoor pool and spa at health club complex.

For domestic and smaller commercial pools up to a surface area of about 150 m2 then the 4 litre container in which Heatsavr is supplied also acts as the reservoir and the screw cap on the container is replaced by a special fitting for connecting to the pump.

For larger pools a 25 litre day tank with bund tank is normally used as the Heatsavr reservoir. For multi pool complexes, each pool will require its own dosing unit but dependant on plant room layout and location of injection points one day tank may suffice.

Independent Test: Thermography Report

The results clearly show, that the surface temperature of the spa containing Heatsavr, has only dropped by 1.5 degrees C, whereas the temperature in the spa without Heatsavr, has dropped by approximately 5.5 degrees C, a difference of 4 degrees C in 1 hour 24 minutes.
