Welcome to our forum.
I think the article mentioned that a third party would do the testing, unless the company involved was ISO 9001 certified, in which case they could test themselves.
DP, could you cite the article, please? Since the Canadian Office of Energy Efficiency in presently working to develop energy standards for Canadian hot tubs, I'm interested. Thanks!
Here you go: http://www.poolspanews.com/2007/091/091title20.htmlTom - the Canadian system is mentioned in the article as well - if Canada has its own system, and it differs from California's system, that's a problem. Plus, lots of states are adopting the California standards, in whole or part, which means 50 different standards here. It could be a mess. I agree, though, that a basic standard is needed - as the article says, a hot tub immediately becomes the biggest energy hog in the house.
