Product Description

PRESTONE Driveway Heat Calcium Chloride. Nothing de-ices driveways, walkways, and steps faster or at lower temperatures. Driveway Heat is a concentrate, not a blend of ineffective de-icers. Don't be fooled by imitators.....Driveway Heat ice melter is the concentrated real thing. HOW IT WORKS: Driveway Heat ice melter produces an exothermic reaction as it works, giving off heat. The heat enables the product to work down to negative 25 degrees Fahrenheit. Other ice melters lose effectiveness at 20 degrees Fahrenheit.

4 Pack Prestone AS500 9-1/2 lb Driveway Heat Ice Melter - Shaker Jug Review

Prestone Driveway heat is superior to sodium chloride (rock salt) in several dimensions. Calcium chloride has a lower melting temperature and is less corrosive to concrete. Additionally, the jug is a superior container to large paper bags. The downside, of course, is that it is expensive. Deicing a large suburban home for three months a year could cost hundreds or even thousands of dollars.

The jug is excellent for use near home entrances as it can be conveniently stored indoors. Just reach outside and quickly sprinkling the salt outside the door. This is much easier and neater than reaching into a 40 pound bag and grabbing a handful of salt.

This lower melting temperature offers some additional benefits when used creatively. If you would like store frozen foods and don't have dry ice handy, a frozen 2 liter bottle of a saturated CaCl solution may work. In practice, temperatures of 25 degrees F are feasible, which will generally not be cold enough to store ice cream for more than a few hours or so. Exceptional insulation may make this more feasible.

It is possible to use the product to cut your summertime electrical costs. By freezing a two liter bottle of saturated CaCl solution at the lowest setting in the freezer in the evening, it would then cool the freezer during the day when the freezer is turned to the warmest setting. This general concept works with frozen water as well but the melting point of water or even a water/NaCl solution is too high in practice. Regular ice bottles made in the freezer at night and then transferred refrigerator during the day can accomplish this goal.

Refrigerators generate an exceptional amount of heat, so taking steps to get the most use of out them when the air conditioners are not stressed can save electricity. Moreover, late in the evening, the aggregate electrical grid consumption is at a trough, which reduced strain on the local utility. Smart electrical metering can turn this strategy into a larger savings.
