Welcome to our forum.
Hot Spring Ace-----"I almost responded to some of those items including the misinformation on the heater, the fact that the added insulation might make it close to equal to the Hot Spring, I think the pump HP is pretty much identical... but at that point I figured why bother. It was definitely good salesmanship by someone but Sundance is a good option as well and hopefully the spa will treat the new owner well for many years to come."1. Can you clarify "misinformation" on the heater---it is my understanding that the Vanguard does NOT have a titanium heater option--it only comes with Stainless steel? The Vanguard heater IS titanium and has been for years now2. You think that a 2.0 pump and a 2.5 pump are "pretty much the same?--Not that one has 25% more power? pump size means absolutely nothing...jet to pump ratio, type(s) of jets ie what type of volume and how the spa itself is plumbed...in other words wet test, wet test, wet test3. "Eco Wrap" is not trying to catch up to HS it is passing it in economy.--just a thoughtOf course you are the expert but it seems to me that a superior fact is not "a better salesman"---it is a better product--let's separate facts from opinions here--that is what the readers are looking for---not opinions---or spin.----just a thought. Meh, I've been selling Hot Spring in Minnesota for years...we also use wireless appliance meters to monitor power, even during the coldest months in MN a Hot Spring doesn't exceed $30 per month (we pay between 7-10cents per kw/h here typically) under a $1 per day in an extremely cold environment is good enough for me

I'll take your word for #1---I did not substantiate--so according to you--Vanguard has a Titanium heater--fine#2 Pump size in your mind means nothing---that is just in your mind--bigger is bigger---other factor of course influence th overall effect but pump size DOES mean something---#3 What's good enough for you---does not set the criteria for a sound decision--your points in this answer are all irrelevant to the point--the point being that more efficient insulation is ---well --- more efficient and it ='s lower cost-- So if Eco Wrap cuts the bill 25%--then it cuts the bill--if your energy is cheap and you don't care--or it is good enough---good for you--but for an apples to apples comparison---"good enough" is not an answerCalifornia btw pays about 0.31 per kw---not 0.07
I'll add to #3 to give more specifics since that was asked for. Most spas that are foam filled use a 1/2 lb insulation and simply fill the cavity with it. Hot Spring uses a dense foam on the shell, on all sides and on the bottom and then fills the inner cavity with the lower density 1/2 lb foam. That layering is largely responsible for the increased energy efficiency and why a spa with just 1/2 lb foam will never insulate as well.

ALL the independent information I can find has always said polyurethane foam has an R-value of R-5 to R-6, per inch, regardless of density. You seem to be saying that a much higher density has a much higher R-value. Can you refer me to any independent information I might have missed? (My understanding has always been that the high density foam on the shell is to add to the structural support of the shell, and the bottom layer for durability under the spa [1/2 pound density wouldn't fair well during transportation].)

It would be great if that came out at some time.
