Insulation on a hot tub

Can anyone out there in the Hot Tub world tell me the difference in R=value between foam-filled and non-foam filled spas?

That would depend on the amount of inches of foam, the density of the foam etc...  Every manufacturer has a different take on this.
Measure once, cut twice.

Our Hot Springs dealer told us our tub has an R value of 39-40 on the sides.  R value is not a great estimator of efficiency as at some point you reach the point of diminishing returns.  Yes, R40 is great and our tub is toasty and cheap to run.   That doesn't mean R30 is bad.

I think a good hot tub cover is R-20.

For non-foam I would imagine the R value fluctuates depending on how much the pumps are going, the outside temp, wind, etc.

This is such a worn out topic.  Please search this site for "full foam" or "thermal pane" and read to your heart's content or until your stomach loses it's contents.

LOL!! ;D

My Tub has an R 3000 though I've heard some have an R 9001 but that just seems preposterous to me... ;D

Sorry play 23 but everyone will tell you theirs is best. Some will tell you R value means nothing and that there's no way to determine it accurately. Anyone remember tht post? I think it came from H2O2?

let's face facts, if a hot tub isn't energy efficient not many people are going to buy it right???  so if you go with a name brand tub you won't have any worries.  no matter if it is full foam, partial foam, thermal lock, etc....

If companies like Hot spring, dimension One, beachcomber, marquis, coleman, sundance, etc.... nade tubs that weren't energy efficent they wouldn't be in buisness for as long as they have been.  Start focusingf on the more important stuff like comfort, style, and jet placement.  And also if the dealer is reputable or not, and makes you feel comfortable with them and the product they are selling you.

That looks to me like a full-foam spa with some voids. I know they blow the hot air from the motors around in one of the air gaps, but I still think that the bulk of the energy retention is coming from the foam insulation. I love the way they use the word "polyfilm" instead of "sheet of plastic."

Oh well. I'm in for it now...

Ohh man, I'm going to track you down at NSPI like a dog! >:(

Polyfilm is a specially engineered product by the owners brother who knows an engineer. ;) ;D

Cool, does he let him wear the hat, pull the whistle cord, and yell "Chooo  Chooooo "??  That would be the best part about knowing an "engineer".   :P

Aren't garbage bags made from polyfilm?

As long as a tub has insulation you should be fine!
