Perfect size tub, took a few days to heat up, but still gets to 104 in Colorado winter. I'm thinking that the 220 hardwired version might heat up quicker or maintain heat longer than the 110 in cold climates, but ours is still fine. It only drops approx 1 degree every 30 minutes when in use in sub freezing temps. Easily moved it to back of house with 4 guys and straps. Still trying to figure out how to balance all the chemicals and chlorine with an ozonator. The ozonator just helps sanitize your tub, it does not eliminate the need to chlorinate and treat. All in all for the price, it's such a great hot tub, and couldn't be happier!
