You need to reheat above 180 to ensure bottles are sterilized. I usually aim for 185-190 so that the temp in bottle is about 180. Carefully not to get much above 200 or you can cause more nitre to form and have to refilter! Also, make sure to turn bottles on their side for at least 5 minutes so that interior of cap is sterilized as well.
