Agreed, but that's got nothing to do with being able to heat hot water. On that thought, what is hot water? How hot is actually hot?
In England, a rubber garden hose is a hosepipe. In South Carolina, I imagine that crack pipes are far more prevalent.
OP - if you’ve got any smart home stuff you could get some water leak sensors to put in the pan. Won’t stop a leak but it’ll tell you when it goes.
My Mom had one in her house. After we had to move her into a home, a trust company was managing the property when the intake line corroded and burst (best estimate was that it happened on a Friday). A neighbor managed to get ahold of someone who came by on Sunday afternoon. When they raised the garage door, two inches of water came rolling out of the house. All the drywall, electric, floor coverings, and cabinetry had to be replaced.
you don’t really need smart home even though that’s nice too. I have two wet floor sensors. One turns the water off to the whole house if it detects moisture On the basement floor or drain pain, the other cuts the power on the water heater. Cheap insurance and easy to rig up. about that time the terrier got into the equipment room and moved a sensor with her nose while I was totally soaped up in the shower.....
