New design technologies, processes and materials are contributing to the constant innovation and enhancement of modern hot tubs. Today’s designs not only improve the bather’s overall health and wellness, they serve as relaxing social centres for family and friends.
Over the past several years, hot tubs have grown to include niche models that target needs ranging from soaking and relaxing to exercise and therapy. In this diverse age, for example, the swim spa illustrates the creativity behind these products and how they can serve multiple purposes such as exercise, therapy and rehabilitation. In fact, swim spas are one of the fastest growing segments in the hot tub industry, as consumers can now choose a model specific to their health and lifestyle needs.
As exciting new designs and styles continue to emerge, manufacturers have to seek ways to differentiate their products from the rest. Features such as curvilinear lines have revolutionized exterior hot tub design, while soft, organic forms offer a refreshing break from old-school hot tub prototypes.
As modern hot tubs cannot have flash without substance, features like high-performance massage lounges with tactile therapy designs for increased hydrotherapy are also important. A combination of light emitting diode (LED) illumination systems and water features are often part of the package and help set the mood with a variety of sights and sounds.
Energy efficiency standards
When it comes to energy efficiency standards and eco-friendly features, hot tub design has vastly improved. The California Energy Commission in the U.S., for example, has created energy efficiency standards all hot tubs must meet, while in Canada the Canadian Standards Association (CSA) is currently evaluating an energy performance standard (C374) for spas and hot tubs.
With both Canadian and U.S. governments taking climate change more seriously, several consumer products are being evaluated to increase efficiency standards. Modern hot tubs from reputable manufacturers are much more energy efficient than they were several years ago.
The industry has benefited from increased efficiency in overall construction methods as well as in motor design, while some manufacturers have increased efficiency through the use of smaller circulation pumps, rather than using the hot tub’s jet pump for water filtration.
New cover designs have contributed to better energy efficiency and improved insulation techniques and materials are giving manufacturers the upper hand on heat retention, which helps lower overall operating costs. New control systems are also providing programming flexibility to schedule filtration cycles, further lowering ownership costs.
