I use a 25' Pirit hose. I put my in line water filter in the convenience center so it won't freeze and that in turn puts the thermostat well below the floor. I also put a piece of foam in the access hole to keep the cold out and the heat in. We have a private site in the place where we get the cold weather (usually down to 10 or 15, but have seen zero) so I wrapped separate heat tape and foam insulation on the spigot. When it gets really cold I go farther South. Have had no problems in 3 yrs of this set up.
