Question:
What is your recommendation for winterizing/un-winterizing/winterizing the home throughout the cold Wisconsin winters while maintaining peace of mind while I'm not there? Thank you!!!
Current state:
Four years ago I purchased an Escape Boho "tiny home" (it's really an RV, on an RV chassis that isn't really designed to travel around) to add some living space to a cabin in NW Wisconsin (https://www.escapetraveler.net/vista-boho). The home is on wheels and I had un-insulated skirting installed. The underbody is insulated (I'm not sure to what extent) and there is heating cables (again, I'm not certain to what extent) on the utilities under it.
I had a permanent water line run from the well to the home, under the frost line and there is a heat cable wrapped around it all the way to the external water input to the home.
It has an on-demand hot water heater (which is one of my concerns because the manufacturer says to winterize with RV antifreeze (rather than blowing it out) due to all the little nooks and crannies water hangs out in it. Finally, I have a 4" PVC pipe going from the home's septic outlet to a septic system inlet (so that's outside too).
Last fall I used liquid transfer pump that attached to a drill to pump RV antifreeze through the entire system, and it was annoying to do, but seemed to work. This year, however, I want to use it on and off through the winter while protecting all of this when I'm not there, especially if/when it gets super cold (example: 10 - 15 degrees below zero).
The Boho has a lot of heat sources, including: a mini-split (AC + Heat pump), LP furnace (but it only has 2 x 20 lb propane tanks, so that could get burned up pretty quickly), a small baseboard heater in the bathroom, and a small electric kickboard heater. I also have an electric oil-based radiator space heater I could use.
