Welcome to our forum.
I would suspect that most people in this situation just hire a neighbor or service company to check the property on a regular basis.By the way, if you plan to leave the tub unattended for several weeks at a time, how are you going to handle sanitation/regular maintenance?
You could set up a remote webcam fairly cheap (assuming you're paying for broadband at the vacation home year round). Â Only problem is that if power goes off or internet service goes offline, so does your monitoring. Â Then you'll be wondering if it's a serious issue or if the power just momentarily went out. Â You could put everything on a 60 min UPS backup (monitoring setup - not the spa), but you still could be getting a lot of false alarms depending on how reliable your ISP is.Maybe a local property management company could check on the place for you once a week or so? Â A neighbor? Â Nearby family member? Â If you don't use it year round, you might be able to work out a trade w/ a property mgmt company - they check on it weekly & give you a report & in return you let them rent it out one week a year & keep all the $ from the rental.I don't know if it would work, but maybe run 2 aquarium heaters into it. Â Ones deisgned for large (100 gal) tanks. Â with their thermostats set at about 3/4 they'd never come on unless your water temp went below about 80 deg. Â They're probably not enough to keep the water hot, but should be enough to keep it above freezing at least. Â Again, no good for an extended power outage though.
Hello All,Worse, I am worried about what happens if the GFCI breaker trips while I am away. Â Full-foam or thermopane construction, either would freeze when the spa is without power for days.
 Regarding the water maintenance, this is what I am trying to figure out.  Ideally, I'd like to select a tub that is inherently low-maintenance, and start from there.
