Can I put a stronger heater in my HotSprings Grandee?
bud16415:
I haven’t only once or twice turned the temp up when I was in the tub. I have had guests that asked for it to be dropped a degree or two when we were in. If it is 10 f outside and I want to take a soak after dinner and I know the tub is on 101 I turn it up to 103 at least an hour or two prior to getting in. My Caldera has had no problem holding 103 for the length of my soak at zero F and it is just a 20amp heat source. Asking it to warm the water with the cover off and the jets going is a much larger job IMO and at zero outside I would expect if I got in 100f water it would still be 100f when I got out regardless what I changed the setting to. Maintaining is much different than maintaining and raising the temp at the same time.
I judge my tubs ability to hold water temp without adding much heat by watching the cover and the outside. I have never seen any sign of snow melting on top or any such heat loos out the sides. I think 20 amps is more than enough for any well insulated tub to maintain any temp well below zero F outside. We have been in the tub when it was sub zero out and to be honest at that temp if the tub is 104 and with a stocking cap on 15 to 20 minutes is a nice soak time. If it did drop to 103 during that time I wouldn’t notice. Now if it is a nice calm night 32f and the tub is 102 with friends we have soaked for a couple hours before with people getting in and out a few times.
For me with anticipation I don’t think I need more power and we live in one of the coldest places in the country. It is great the OP found a solution that works for him as well.

It has been getting brutally cold here in MA and I went into my tub last night with outside temps in the high 20's. My tub was set at 100 and it maintained that temp for the 25 minutes I was in it.
I did turn the temp to 103 but the temp never made it above 100 while I was in it. So it appeared that 28 degrees or so is a good starting point for temps that make it hard for my hot tub to heat the water beyond the current temp.
Just curious. I have a Marquis Promise two pump spa.

I keep my Marquis Resort at 102 and it maintains it in the cold weather. If I turn it up the temp doesn't rise on it until I shut the cover.
