Energy Efficiency

What are the benefits of ACE and how does it work?

Posted in Energy Efficiency, Health Benefits, Spas by hotspringd on the January 30th, 2010

Benefits

The ACE system is an advanced salt water chlorine generating system designed specifically for the Hot Spring Spa.  The benefits of a salt water chlorine generating system over and above the obvious (less work to maintain your water chemistry)  is that the ACE system does NOT depend on expensive , harsh chemicals like chlorine, bromine or other man-made santiziers but rather salt, a much cheaper commodity.  With the ACE system, the soakers do not have to worry about green hair, itchy eyes or skin problems, or storing large quantities of harmful chemicals.  While pH levels still need to be tested, there is less work involved in maintaining an ACE spa versus a spa treated with traditional chemicls.

How does it work?

Natural non-iodized salt (sodium chloride) is added to the hot tub water.  The salt is comprised of two elements – Chloride and sodium.  The ACE system has a cell that is installed within the hot tubs 24 hour filtration system that houses and special electrolytic cell.  As the water is pulled acrossed the cell, it electrifies the salt water, producing a simple, natural form of chlorine.  This system is also checking the salt water levels of the hot tub to insure that the levels are not too high or too low.  If either case occurs, a warning icon will displayed to alert the owner tha some minor adjustments need to be made.

Chlorine Cycle

This freshly chlorinated water is circulated into the hot tub so its sanitizing properties can kill bacteria and viruses.  The cell also produces an effective oxidizer cleaning the water and giving it a pristine apperience.  Eventually the natuarl form of chlorine is used up and reverts back to salt’s original two elements.  The ACE system is a closed loop system therefore once the chlorine is reverted back to salt, it is available once again to generate more chlorine.

Additional Chemicals and Maintenance

The ACE system is effective with virtually any water supply.  After the initial fill, the owner simply adjusts the waters calcium levels, pH levels adds salt, tells the system the level at which the hot tub will be used and its size and the ACE is off and running.  An occassional test of the pH levels and a monthly confirmation of the hot tubs usage is all that is needed.

The cell may need an occasional cleaning which is easily done with vinegar on the side of the hot tub.

   

Watkins Manufacturing Earns First European ENVY Award

Watkins Manufacturing Earns First European ENVY Award for Energy-Efficient Hot Spring Spa
Vista, CA- Watkins Manufacturing, maker of Hot Spring® Spas – a top-selling worldwide brand – has received the first-ever European ENVY Award for its outstanding efforts in environment-friendly hot tub design.

Vista-based Watkins provided a Sovereign® spa for testing in realistic outside conditions by the INDESIGN Institute for Innovative Design, a research-and-development institute near Munich, Germany. The Sovereign spa was installed at a demonstration home operated by INDESIGN partner DemoDomo. DemoDomo serves as a platform to demonstrate, test and develop innovative and energy-efficient products.

From December 2007 to February 2008, INDESIGN tested Hot Spring’s Sovereign spa continuously for energy efficiency in cycles of 72 consecutive hours. The spa was found to be well within the maximum standby energy consumption set by the California Energy Commission.

Its name an acronym for “environment-friendly,” the ENVY Award recognizes Watkins Manufacturing for:
Creating trendsetting, energy-smart spas

Using energy-efficient spa components

Participating in frequent product testing carried out by independent third parties
Assuring that all spa owners and prospective buyers have access to valid energy-performance documentation

Supporting international R&D to further develop green initiatives and increase energy efficiency
“Hot Spring Spas decided to actively join this project as a primary cooperating partner because company management is open to new ideas and suggestions,” said Prof. Dr. Ulrich Beerschwinger, founder and director of INDESIGN.

“They take energy efficiency very seriously in the manufacturing process and consumer use of their spas. Our exhaustive investigation of spa efficiencies reported in several tests has proven Hot Spring is a leader in energy efficiency.”

Steve Hammock, President of Watkins Manufacturing, accepted the award from Beerschwinger on March 19 at company headquarters in Vista, Calif.

“We’re honored to be the first recipient of this impressive award,” Hammock said. “It is an affirmation of our commitment to energy conservation and building ‘green’ spas.”

times per week; 15 minutes with the jets on, 15 minutes with the jets off
during each use. Testing conducted in a Controlled Environment Chamber using
continuous Data Acquisition monitoring equipment including Continuous
Progression Kilowatt Recording meters, Voltage Measurement probes, Current
Measurement probes, Relative Humidity Chamber Measurement probes and
Thermocouple probes. All equipment was rigorously calibrated to insure data
accuracy.
