We will be moving to the Salt Lake city area soon and was set to order a Bullfrog X7 tub since they are manufactured right there. I just saw a recent review of the tub on their website that in short said...
"We recently purchased an X7 tub. We live in Wisconsin and enjoy using the tub in the winter. When the temperature is below 30 degrees the tub will loose several degrees an hour even in the standard mode and the heater light indicating that it is heating. We contacted the service department where they bought it and they stated that the tub comes with a 4K heater that may not be able to keep up. We could run the tub without the jets to help with the heating. They stated there isn't an option to upgrade the heater to the 5.5K model. If you like using your tub in cold weather, I'd suggest a different model."
I like using hot tubs down to 15-20 degree outside temps. The problem is it appears most of the other top brand spas all use a 4kw heater elements also. There will be no problem with wind, but the air temp does get cold. Though the factory says there is no way to upgrade, are there aftermarket heater elements that will work? I am open to other tubs in the same size without a lounge if the heater will be an issue.
Thank you for any suggestions!
