The CEC doesn't test spas....they simply republish the information as provide by the manufacturers...and even if the results are completely honest, the testing procedures are in no way a real world test.A few years ago, a buddy on mine was an engineer at a spa manufacturer. At the time he was working on trying to get their spas to pass CEC guidelines. Spas were being tested in an indoor temperature controlled enviroment. they were very easily able to get an operating cost in 24 hours of testing. Long story short, I asked him grab a fan out his office and direct it at a spa. Called him a couple of days later. Laughing, he refused to give me any information, other than there would NEVER be another fan in the test room. E V E R
