Will running heat keep pipes from freezing?

if it's de-winterized, you shouldn't even need the heat. what you need to watch for is when you re-introduce water into the lines, you really have to pay attention to the temps. if it is only in the mid 30's it's not so bad, but when you get to sub zero temps...watch out..you can camp all year round even in the cold if you know what your doing...not that I'd ever want to.
