good as far as baseboards go... but there's still regular water pipes you may need to worry about down there. some people set their sinks to drip... I don't think this is reall necessary. Since you have oil hot water, it's 2 fold easy fix is to just run the facuets on hot for a few min that you don't really use (like, the spare bathroom, etc). The kitchen sink is probably fine as is the master bath because you use them and the warm water flows through it a few times a day. The drip doesn't really warm the pipes though.. it just keeps it moving, but I don't think it's enough to stop it from freezing up. I'm planning to run my COLD water on my sinks for a little bit before I go to bed and then again when I get up tomorrow morning in the -6 they are planning for us. the hot water is probably fine-- the line from the street is going to get cold!
