Welcome to our forum.
I have been looking at an Arctic Spa and I am not sure about their claims for using less power to heat, but I do like the idea of being able to access all areas of the underside without the foam interference.
a different spin on this might be, is one loader than the other. IMHO FF is quieter.Ray
I sell both types, Coleman and Jacuzzi. Side be side in the showroom the Colemans are quieter.
