Welcome to our forum.
Just wondering about how long it takes to heat a tub to 100-102 degrees? Is 6-7 degrees an hour slow, or is that about right? I haven't gotten a spa yet, but I'm just thinking (dreaming) ahead!
when its 16 degrees outside, thats when cajun1 is asking about how long it will take to heat up.
I live in FL so I have absolutely zero experience with cold weather. With that said, if one is on a 4 month water change cycle, isn't is easy enough to schedule water changes around 16 degree weather? Obviously this would not work if you needed to do a water change outside of your normal cycle (like when that nasty brother-in-law brings his whole fam over for an uninvited week... 8-))
