Finding the Right Spa Cover
All this talk about going green, a big part of saving the environment is to not create more waste that will just end up clogging our land fills. Follow me on this for a minute… There are 10 million spa owners in the USA, and each one of them uses a typical rigid foam spa cover on their hot tub. For the sake of this demonstration each foam cover is only two inches thick and every spa is eight feet by eight feet. That would mean each spa cover contained about 10.666 cubic feet of foam per spa cover. For the rest of this example we will use 10.5 cubic feet per cover.
Spa manufacturers are building all sorts of shapes and sizes these days that can be purchased and delivered to your home and covered easily. But for high end custom built spas, that often cost six figures it is not so easy. Unfortunately far to often it is after the spa is complete and the owner gets their first heating bill that they think about a cover.
These spas are often featured in spa magazines and truly look amazing. Who would not want one? They look like theme park attractions you can own. They often feature natural looking rock walls and water falls, spill ways and infinite edges so that while you sit on the spa you can see the landscape beyond. All very impressive and expensive. Unfortunately heating and keeping debris out of such a work of art can also be an expensive proposition.
If there are 11 million Cubic yards of stone in the Great Pyramid at Giza, we are adding enough foam to build a duplicate of it to our landfills just from used spa covers every six years conservatively. There are four and a half million cubic yards of concrete in Hoover Dam. We could build a two lane highway of discarded foam filled spa covers from Seattle Washington to Miami Florida every two years.
If you are considering having one of these spas built, make sure the designer is including a cover into the process and that it does offer insulation. Just having a safety cover anchored over the spa is not going to keep heat in or debris out. To insulate the water when the spa has different heights around the edge such as a spillway, the spa cover should actually rest on the water. By coming in contact with the water the insulating cover will cut down evaporation and chemical consumption too.
Heck with parking lots, in a few years we could pave the entire planet with foam just from saturated foam spa covers from the USA alone.
