Welcome to our forum.
It's not fair to say your tub was fine even though the water in the vessel was still 102 degrees. It is very possible that water in the plumbing lines surrounding the vessel can freeze while the water in the vessel maintains temp. Be careful. 15 hours you should be fine but if it gets real cold you could have warm water in the vessel and frozen pipes and pumps.

The spa in general is well insulated but not all area are equal and its not the main body of water you want to concentrate on. Next time if you have a generator try to run a light into the equipment compartment to let it warm up that area somewhat because while the main body stayed to temp the water in the equipment and hoses in that equipment compartment certainly dropped and had it lasted far longer you could have run into issues.
Don't panic about a generator. When you really think about power outages and when they occur. Someone hits a power pole, very rare.
I just recently bought a tub. The delivery of the tub is about the same time that I go for our 3-week winter vacation. What if the power outage happens while on vacation???1. Winters here in GTA, Ontario is generally -10 to -20 Celsius. How long in this scenario before freezing can occur. Mind you I would tend to run it in low range heat cycle (70 to 80 degrees Fahrenheit) when on vacation.2. What type of remote monitoring/notification people are using in the event this happens. Thanks,
Would it be possible to not fill your tub until you return, or have them deliver it after you return?
