Though I do not know what specifically the chemical is, it is certainly a molecule with a hydrophobic (water-hating) portion and a hydrophillic (water-loving) end. The water loving end is either charged or polar. The substance is less dense than water so that it floats on the top. All of this leads to a single molecule thick layer when the water is undisturbed. The molecule should be resistant to oxidation from chlorine so probably has no nitrogen sites in it.

If it smelled like an alcohol, then it may indeed be an alcohol which just means it has a hydroxyl group and if that group is on the end then in fact it could be this chemical. BUT, it will not be ordinary alcohol (ethanol) since, as was pointed out, that DOES dissolve in water. So I suspect that the alcohol has a long carbon chain -- at least 5 or more carbons since pentanol is not very soluble in water and is less dense than water. Perhaps 1-hexanol or something even larger.

Heatsavr Patent

Postby Bake » Thu 19 Jul, 2007 15:16

Chem Geek, If I recall correctly this is the patent for Heatsavr. The original use is for evaporation reduction in reservoirs. Heatsavr, I read some place awhile ago, is just this powder mixed in alcohol as a carrying agent. I hope this helps. I purchased Heatsavr in bulk (4 gals.) and the chemical pump, but since I have not even opened the pool yet I have not been able to try it yet. The link:

Thanks. That answers the question. The product is just a combination of "an aliphatic alcohol component having from 12 to 24 carbon atoms per molecule" combined with calcium hydroxide. It's basically what I said -- a long-chain alcohol. The calcium hydroxide is just a carrier and dispersing agent. It is the alcohol that is the key ingredient, not the calcium hydroxide, though the patent is about combining the two so that the delivery of the alcohol is part of what is patented.

The preferred embodiment uses cetyl alcohol (1-hexadeconal) so you could just buy some of that to add to the water (it only takes a small amount as the layer is only one molecule thick), but the use of the calcium hydroxide sounds like it helps disperse the product because the hydroxide dissolves first leaving charged calcium behind that tends to repel and spread the alcohol across the surface, then the calcium itself dissolves. The product isn't that expensive -- it works well so long as there isn't much wind.

Heatsavr

Richard:

The Heatsavr is actually relatively expensive. I paid around $300 plus shipping for the injector chemical pump, one time cost, and $220 plus shipping for 4 gallons of the Heatsavr. The 4 Gallons should be enough for my 28' x 52' pool for the season. I got it form Solardirect.

Sorry. I was thinking of SolarFish, not HeatSavr. I wonder what's in SolarFish? Probably a similar chemical, but not in powder form (it feels like it's already a liquid).

Heatsavr

Postby Bake » Fri 20 Jul, 2007 14:44

I don't know what is in SolarFish but the same people that make heatsavr are the same people that make Tropical Fish liquid solar blanket, and the liquid in the Tropical fish is the same as in Heasavr. Heasavr is just the bulk vertion. The difference between the powder in the patent linked above and Heasavr is that the "powder" is mixed I belive with regular alcohol. They even say in the instructions I read some place that if the Heatsavr freezes the powder will come out of solution, but will go back to normal at higer temps. It has been awhile and I don't have a link for it, but the Heatsavr has its own patent and thus the high cost of the product. Again when I finally get my pool open ( I have been dealing with a major flood cleanup, frozen pump motor and leaks) I will try the Heatsavr and give everyone a report. My pool normaly holds a 76 deg. temp (except on the very hotest days) with out a cover or heater.
