110v or 230v
« on: February 21, 2021, 05:56:40 pm »
So i just brought home a 2013 Hot Springs Jetsetter JJ.  The previous owner had it connected 230v.  i have the tub installed indoors so my question is can I convert this back to 110v will I really see that much of a benefit by connecting 230v?  110v I can handle myself, 230v i would need an electrician $$.  My thinking is with it being indoors the tub will not be struggling to heat up and maintain the temps as it would being outside.  Any input is appreciated.

Thanks

If you  an handle 110v, you can handle 230v. I understand that it seems more difficult. The tub will need a dedicated  circuit in either case. To convert right, you need a dedicated 120v outlet (nothing else on that circuit) and it needs to be at least 20A. You still need either a GFCI cord or a GFCI outlet.

If you have to run a new circuit, I would just go 220V. You can either run a 50A circuit to a spa panel (with a GFCI breaker in it) or do a 50A GFCI into a disconnect panel and then seal tight to the tub.

220V will heat faster, close to twice as fast. Can this tub run the pumps and heater on 110V? Some can and some can't.

I ran 220V for my tub. It was more upfront cost as 6-3 is more than 10-2 but mine will be on an enclosed porch and the benefits of having 220V made it worth it in my eyes.

I have owned 2 Jetsetters since 2005 and both were wired 110.  At first I was concerned about heat loss (mine is outside on a deck) but those fears were allayed the first winter.  Even on the coldest nights, I would stay in the tub with the pump on for close to an hour sometimes and the water never dropped below 102 (usually set at 104).   So for me, it was not worth the extra expense of installing a 220 hot tub box when my 110 with a 20 amp GFCI outlet worked just fine.    Even from a fresh fill, my hot tub is always up to full temp by the next evening so I can't imagine wanting or needing it to heat up any faster than that.   But, to each his/her own.   Happy tubbing!

The dedicated 110V circuit is the important part. I could have gone either way but I went 220V. I had a 110V tub years ago and it was slow heating and struggled to keep temperature when using it.

Yes 6-3 NM-B (romex) is more but depending on the run, not all that bad. Lowes has 6-3 NM-B romex for $3.54 a foot ( which is less than just about any electrical supply house right now). 12-3 runs close to $2.00 a foot and 10-3 NM-B (which is what I would run if it's any distance to the panel) is about $3.00 a foot . Either way, you need a GFCI protected circuit and a disconnect panel. A 110V plug in would need a GFCI cord or you could direct wire it but it still needs to be on a GFCI circuit with a way to disconnect the tub.
