Welcome to our forum.
Those are self reported numbers and those R values are from who knows where.Check out how D1 has spa R values of 6 for all their spas (not counting swim spas), Master has 12.8, Clearwater has 20 and Artesian has 22. Those R values are all over the board yet they all report similar standby watts. What does that tell you?
Until they come up with verifiable standards and require third party testing, the CEC certification is useless.
Exactly,This proves what many have said all along, the CEC admission standards are a joke. Â
It’s not the standards that are a joke but the manner in which the data is captured, by the spa company itself. It's sad that a few of the companies on that report whose spas regularly get complaints for energy efficiency will use that report to their benefit. I've even seen it touted by someone on this site as verification of a certain brand that I wonder about. I'm still hopeful that eventually this may become the start of something that will be require verification and may even be tightened. We shall see.
There was a third party test done in Aug 08, at the University of Polytechnics California. Only 27 manufacturers showed up and this is why:  I couldnt post the entire file so if you want it I will email it to youTable 1: Summary of (nontemperaturenormalized)test resultsSpaTested Volume (gal)  Stand[ch8208]by Power (Watts)   % above or below  Measured  AllowableA   185   141  162  -13%B   264   163  206  [ch8208]21%C   398   197  271  [ch8208]27%D   282   320  215  49%E   440   338  289   17%F   200   218  171   28%G   300   192  224   [ch8208]14%H   150   190  141   34%I   370   249  258 [ch8208]3%J   334   479  241   99%K   142 81  136   [ch8208]40%L   220 95  182   [ch8208]48%M  300   119  224   [ch8208]47%N  235   277  190 46%O  345   330  246   34%P  247   238  197   21%Q  439   437  289 51%R  296   411  222 85%S  293   318  220 44%T  150   140  141  0%U  470   304  302  1%V  350   136  248 [ch8208]45%W  382   226  263   [ch8208]14%X  422   313  281 11%Y  200   270  171 58%Z  260   223  204  9%AA 219   251  181 38%
As you can see only 9 spas actually passed CEC standards and 3 of them  K, L, and M are Softtubs with no heater. Now maybe you can see why so few people know about this "third party" test.
This Cal-Poly test was done after most of the self reported results.
