Had my spa (Sundance Hawthorne) about 2 months. This is full foam insulation too. Based on the same months last year my electric bill has gone up approx $25, but that's with it being used at least one hour every day.
I have had my Sundance Cameo (2009 model) for about 5 weeks and just got my first energy bill from Pacific Gas & Electric. I live in a mild climate on the California Coast where average temp right now is about 62 degrees. My electricity bill went up $150 dollars from last month. We do use the spa alot, almost every day, and have the temperature set to 103 degrees typically. We were low energy users before the spa and were paying less then $40/month for our energy costs, so you can say I was a little surprised to see this bill.
Does anyone think that the electrical hookups could be contributing to this? The spa was hooked up by a licensed electrical contractor who charged me $720 for parts and labor.
Interesting thing is that I had a cheap Costco spa for 3 months last year and got rid of it for this exact same reason. That spa was costing me about $150/month to maintain from an energy cost standpoint. We are much happier with the cameo for obvious reasons (comfort, features, etc.) but I would like to learn how to save in energy consumption. Any tips would be greatly appreciated. We love the spa just not that steep bill.
