Inflatable Hot Tub Tips!

I want an inflatable hot tub but I live in Michigan. Our winters have been relatively mild over the past few years but we can get slammed by winter storms every once in a while.

How can I set myself up for success? What do I need and what should I do to keep our hot tub running efficiently throughout the winter?

Do I insulate the heater? Do I put it on a foam mat?

Any thoughts and opinions are welcome!

Thanks!!
