As dual hinged foam spa covers get water heavy their insulting ability drops considerably. Tests reveal spas maintaining 100 degree standby temp with a dual hinged foam cover older than 18 months can use as much as 14.5 kWh of power daily. (1 -kWh @ $0.14 x 14.5 = $2.03 per day)
The APSP energy efficiency testing at Cal Poly in 2008 concluded that a Coverplay spa convincingly outperformed all other North American manufacturers of acrylic spas with a 3.57 kWh rating. No other acrylic spa entered was even close to that rating, in fact 2 out of 3 spas tested were so inefficient as to be non-compliant for sale in California. Spas that met compliance were minimally so and cover test results now suggest they would be out of compliance shortly after their sale because of that dual hinged EPS foam cover.
North America uses dual hinged covers and these number in the millions. Using the Cal Poly test results, the Airframe spa cover design could save America millions of energy dollars every month while helping to remove the portable spa from the dubious distinction of, “Most energy consuming appliance in America”.
The California energy company (PG&E) determined from a 10 year study the portable spa to be the most energy consuming appliance in America. Through Title 20 legislation the California Energy Commission now restricts sales of portable spas in California. U.S. Congress bill HR 2454 supports that Title 20 energy bill for enforcement on a national level.
As EPS foam covers become water permeated their insulating capability is compromised. Water, a conductor, makes covers heavy and increasingly more costly to heat the spa. This costs consumers up to 75% more in stand by power.
Until now consumers replaced their old water saturated cover with another EPS foam cover. Water saturated moldy foam covers end up in America’s land fills at an alarming rate of 145,000 per month. Many US cities and countries like China have banned EPS /Styrofoam from being sold there. California and Oregon have pending legislation to be among the first in the nation to ban EPS state wide. An average spa cover represents about 3520 Styrofoam cups or 510.4 million cups a month to our land fill sites in America alone. It can take up to 20 centuries for EPS to break down in today’s land fills as foam board must be protected from the water supply.
TheAirframe spa cover is a rigid aluminum frame with a banded core that insulates with layered chambers of air amid low emissive radiant barriers.
TheAirframe does not retain water, lasts for more than 10 years and can be repaired, recovered and recycled.
The multi air chambered frame is covered in fitted, water repelling, gas permeable fabric for durability and longevity not petroleum based vinyl. Eliminating EPS foam from use in spa covers is a, “Green”, idea that could avoid replacing the equivalent of 7 billion Styrofoam cups in the USA annually and costing spa owners unnecessary millions to heat spas with water saturated covers on them.
