Usage Notes. Many authors of usage guides, editors, teachers, and others feel strongly that such âabsoluteâ words as complete, equal, perfect, and especially unique cannot be compared because of their âmeaningâ: a word that denotes an absolute condition cannot be described as denoting more or less than that absolute condition.
A solar blanket or solar pool cover gives you free heat from the sun. They are somewhat similar to bubble wrap (only made with more durable material). You can buy this in big sheets that you cut yourself to fit your pool. These are definitely the most economical way to raise the temperature of your pool.
Pro: One advantage of solar pool heaters are that solar is the least expensive way to heat a pool. After the initial purchase of the solar heating panels you receive free heat from the sun. If you have a southern exposed area large enough to install at least 50% of the pool surface area in solar panels, and it's close to the filter system - you can very effectively use solar pool heating.
