| Heavy spa Covers are big reason to Waste Energy |
Various people believe weighty cover as a strong and good to hold heat. But heavy and broken Spa Covers waste energy. There are various websites of spa covers companies which are selling rigid foam spa covers that life will end up heavy or broken, typically within two years. To me this is like a coat salesman telling you wet wind breakers won't keep you warm, here you want to buy this new dry wind breaker and go play outside in the rain.
The broker hopes that you won't note that he's selling you the same thing you're replacing now. If you're replacing your spa cover because it got weighty, before you buy the next one, may be it would be good to think about why the old one got heavy?
The cause of the foam spa cover to obtain heavy is that it traps wetness inside. So foam board is used in many wadding. Generally it can be used around refrigeration storage areas like in a super market. Layers of rigid foam board are what remain the refrigerated section cold while the customer area is still warm. When used in this application the foam is not subject to warm moist steam. As long as the foam stays dry it has a predictable insulation worth. But if the foam were to have wetness in it instead of the little air spaces it uses to insulate, it would have no insulation value at all.
You couldn't acquire water into it faster even if you joined it to the base of your swimming pool. If you were trying to discover a method to get foam to flood as fastly as propable, the design would involve lots of steam under it and a cooler temperature on top of it. Because water molecules are better than steam molecules. Steam can obtain into smaller spaces faster than water. And once the steam cools, it condenses back into water, displacing air in the foam as it does.
One day will appear when your spa cover will becoming weighty, wetness has begun to replace the air spaces in your cover. When it does, the slight insulation value that cover might have had goes down significantly From whatever it may have been when you initially put it on your spa it has gone down to as much insulation as a wet piece of plywood by the time you really notice it got heavy.
You might acquire fooled into thinking that it is still insulating well because snow won't dissolve off it. Unhappily, you would be wrong. Snow won't melt off a frozen pond either but it doesn't mean the ice is insulating the water. When snow falls on a saturated foam spa cover, it freezes the damp in the cover because it is lying straight on the cover. The water of your spa is never in contact with the foam since the foam is resting way up on top of the acrylic of the spa, typically about a foot above the water surface.
