winter and has been for 15 years. It's constantly at 104 degrees. I've replaced the vinyl cover 3 times, but the spa has been completely reliable other than one flow sensor I replaced myself using an OEM part from Amazon that cost $20.

I just make sure the chemical levels stay relatively normal.

Nothing worse than wanting to use the tub only to have to wait to heat it up or clean it. We keep it always hot and and we'll go months without using it, then use it nightly for a couple of weeks than not again for months, etc.
