The CEC – or, California Energy Commission is the only third party accreditation organization recognized by the spa and hot tub industry. This is a huge consideration when you are looking for brands and models that will cost you the least amount of money to own and maintain. You should only consider spas and hot tubs that are CERTIFIED by the CEC; don’t consider hot tubs that are simply CEC Energy “Compliant.” This claim usually means the product does not MEET a minimum energy efficiency standard. Be cautious when another company makes energy efficiency claims. Always ask for proof. The CEC Certification should be a non-negotiable standard. All major national and international brands – like Jacuzzi, HotSpring and Sundance – are CEC Certified and documented.
