Welcome to our forum.
Yah we were borderline on the electric ourselves, but with the amount of electronics in our house I took the plunge and opted for the upgrade to 200amps.
I can't believe the number of people that like to choose to upgrade their electrical service from 100 to 200. Â Consider thisYour AC draws about 12 amps full load.Hot tub with two 2.5 HP pumps (not BS brake HP either) and a 5000 watt heater at about 40 amps.A television, some lights, your computer and other misc. appliances - maybe 15 amps total at 240 v shared load.You 100 Amp service will be just fine unless you have a huge house and multiple AC units.Save your money.The 100 amp breaker may be 100% rated, whether it is or isn't, it will handle a load of 115 amps for about 20 minutes before it trips. Â The wire is all rated for the peak loads also. Â Wait until summer, turn on your AC and heat the tub with both pumps on high, turn on all of the lights on in the house, the tv's too and a hair drier. Â Then have him check the load. Â Now you just wasted a service call because you didn't believe me in the first place.Good luck.
Some of you may remember this thread...http://www.whatsthebest-hottub.com/cgi-bin/yabb/YaBB.pl?board=wtb-hottub;action=display;num=1134612554Well we finally made our decision and our Caldera Tahitian Utopia  is on order.We paid $6895 for it with a covermate assist and full containers of off the shelf chemicals for it rather than the typical starter kit. We are getting a 2006 model (no idea as of yet what differences there are from the 05).Only bad (good depending how you look at it) news I had is when the Electrician came out we have to upgrade our electric from 100amps to 200amps. That's already paid for and scheduled ahead of time (and will work as a tax write off as it's a home improvement;D)So now I am just waiting for it to all fall into place.
That is a SCREAMING DEAL! With the '06 upgrades, you get the "Atlas" reverse molded neck jet seat and the stainless jet escutions. The cost of the spa went up a bit, so..Good job on a great spa and a great deal!
