We purchased our new home about this time last year. When we moved in there was an old… VERY OLD Barefoot Spas on the patio. I think it was from the 90’s. It still worked, and we actually used it a few times, but I could tell it was taking a lot of energy to run it, and we researched that there’s a lot more energy efficient spas now. We called Barefoot Spas and had them go over some differences between the old style of energy savings, and the new insulation they use. We decided to go with Barefoot Spas again. They put us on the repeat customer program… even though we didn’t actually buy the first one …. shhhhhh! We got a great deal, and I’ve noticed an energy savings on our power bill of a significant amount since we added the upgraded unit.
