Insulation and Efficiency
Energy Saver System™
USA Spas looks for ways to make our spas more environmentally friendly. We use a special energy saving system that reduces energy consumption, which helps you save money at the same time. Unlike full-foam spas that need to vent off motor-generated heat, the heat produced by the mechanical equipment is not vented away in a USA Spa - it is contained, recycled, and reused. As water moves through the lines toward the jets it draws air with it (an action termed venturi).
This air is taken from the pocket created by the Polar Insulation on the shell and cabinet. Not only is this warm air recycled and used to warm the water in your jets, but it also helps to maintain the water temperature! Full foam spas have ventilation openings in the cabinet, which allow the warm air to escape. Those holes in the cabinet also allow insects and critters to get inside your spa. Our spas are full paneled with additional perimeter insulation around the entire cabinet keeping warm air inside the spa and saving you energy and money.
USA Spas are built to withstand harsh, northern winters. Our system incorporates insulating Polystyrene panels with an additional layer of reflective Thermofoil as well as reflective Thermofoil insulation on the floor which seals the cabinet from outside air infiltration. As a bonus of this excellence in insulation techniques, the dead air space within the closed spa cabinet forms an insulating barrier to help maintain spa water temperature. This is the same insulating principle as found in the construction of insulating thermos bottles. The bottom of the spa is sealed with a moisture proof material to further protect and insulate. Your spa is fitted with a thick hard cover, which can also be locked in place for safety. We recommend the thicker, highly insulating covers for colder climates.
