It's snowing in Korea and I'm having trouble figuring out this heated floor system. So I've decided just to sit on the floor instead, crouched in a tiny little warm spot between my chair and refrigerator and hope it figures itself out by morning. I thought I got the hang of the heating system until I turned my heat off the other day... trying to save energy and the earth (plus my floors were scalding my bare feet). Now I'm back to sqaure one...watching the thermostat go from 12 degrees to 14 in the past 4 hours. It's going to be a cold winter...
