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.
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.
