Admd67.
I owned a Nordic hot tub. I am not sure if it was the "Crown" sereies or not. I received the tub 3rd hand, it was a round 4 person, open seating tub with aprx 12 jets. 220v, 1 catriged filter and 1 pump, cedar cabinet. I had thouth the tub was perhaps 10 years old, but upon removing it, and going throuh some paper work, I discovered it was only 6 years old.
As mentioned, I got the tub used. I did not have good luck with this tub. Insulation was almost non exisitent. It cost me a fourtune to run in the the N.E Winter ($150/Mo plus). The bottom of the spa was plywood and rotted out. Mice infested the cabinet. The pump were cycle on for no apparent reason.
It sits behind one of my sheds now waiting for the day it will be taken to the dump.
If you are considering a Nordic, I would take a look at the insualtion as well as the cabinet construction. Perhaps I had a very low end model, and hopefully improvements have been made.
