If thermopane style insulation using dead air is such a great idea, why don't thermopane Spas use air filled spa covers?It seems to me that ALL manufactures use FULLY FOAMED covers.I also understand that all portable coolers are FULLY FOAMED.I would also like to point out that acrylic or fiberglass are very poor insulators of heat and allow the heat to be transfered right through to whatever insulation is next to it.Now that is either air or foam.Which is the better insulator to retain heat? Air or high density foam?__________________________________________Air is the worst insulator in the world, Snow makes a better insulation material. But with a heat source (4-8 hours a day of filtering) Air will transfer heat better than foam into the water. But any gains in effieciancy are lost during the 16- 20 hour balance of every day. It's a wash!__________________________________________

steve, i'm curious. why the sudden jump onto the hydropool bandwagon. i thought that you had said that their quality was suspect. also when did they change to this hybrid thermopane design. i have a three year old hydropool 700 series that doesn't have this design.could i just get some foil backed insulation and apply it to the walls of my cabinet to acheive this system. i love my tub but it isn't exactly the most energy efficient thing out there. my electric bill must have jumped at least $60 per month after we got the tub.

Just thought I would share something. I had my basement refinishing contractor and the inspector both out looking at my project recently and asked them if it would be OK if we just put some sheet foam and panel up leaving the walls with a dead air space and made the panels removable so we could repair plumbing if needed. When the contractor stopped laughing, he said that was the craziest idea he has ever heard and that he wanted no part of it. The inspector told me if I was serious he would not sign off on my permit! I told them I was just kidding and wanted to relate my industry to theirs. The inspector has a Coleman spa and asked me after thinking about it if there was a way he could foam his spa after the fact. I know the arguments for both sides here and am not trying to take sides but I thought it was interesting how the conversation turned out from a different perspective outside of the industry. I might have created a monster though because now the inspector is acting like he needs to keep an eye on me or I will try to do something stupid!
Have you ever had your tub metered? Over the many years I've been doing this, I've heard some pretty wild numbers from many different owners of different spas.
As for the tin foil system, I have another contact that could best suggest the proper application. I'll check to see what name he's using this week and pass it on
