How can i keep exposed water pipes from freezing this winter
Protect water pipes from freezing by turning off the water supply to the house at the main shutoff, switch off electric power and gas. You may visit http://www.ehow.com/how_2188259_protect-water-pipes-freezing.html to get the rest of the steps.
It would depend on how exposed the pipes are but I have let the water drip over night and sometimes put a space heater close to the exposed pipes.
Wrap the pipes with insulating wrap then let the taps drip ever so slightly at night to keep water moving. Do NOT shut the water off. Water still in the pipes will freeze.
