Pipes are frozen going upstairs here, too.
DrO said it took 4 attempts and over an hour to get the washing machine to fill.
I'm rotating my sitting between here and the warm kitchen. At heart, I'm still a Southern California sissy...lol... but the thermostat is turned up to a "balmy" 68 today. It's actually a very nice 74 degrees in the kitchen but I'm not about to tell him! Kitchen has two wonderful heating vents and it's a smaller room than this one which has 5 of those huge, old Victorian windows that measure from 2 feet off the floor to 2 feet from the high ceilings.
Too bad about your upstairs pipes. Hope they don't burst. Hubby hasn't figured out what's up with the kitchen water yet. The bathroom is fine.
