PIRIT Heated Hose : The Only Cold Weather Heated Hose
I've got one, and used it last New Year's weekend at Chicot State Park, LA. The daytime highs were in the low 40s and the overnight temps fell below freezing soon after dusk.
They're not as practical as I was led to believe; unless you've got it hooked up to an insulated hose bibb, your water supply can still freeze. So when I used my heated hose, I also used Styrofoam faucet covers (Standard Faucet Cover-1950 at The Home Depot
) on both the park's hose bibb and on my Airstream's municipal water inlet. Had to punch holes in the bottom of the covers for the hose to pass through. And since the park's electrical connection was curbside, not streetside, I had to use an extension cord to plug in the hose's heating element.
I don't know if I'll use the heated hose again this winter for my holiday weekend camping, but I'll have it with me just in case. The main advantage to the heated hose is that you can leave your fresh tank empty and don't have to drain the tank when you re-winterize after the trip is over; that's a cold, wet job in the winter.
Side note, even if you don't use a heated hose and fill your fresh tank instead, one of those styrofoam covers on your municipal water intake and/or your fresh tank fill port might not be a bad idea when winter camping.
