Quick question now that it's super cold. Will an instant hot water circulating pump keep my pipes from freezing up? My house is on pilings and no enclosed underneath so anytime the temps drop below 30, the pipes freeze up. My main water line going into the house has insulation and heat tape so it's fine, but the branch lines to the bathroom and kitchen were unfortunately installed between the insulation and sheathing and freeze fairly easily. I would like to put a circulating pump under the bathroom sink and kitchen sink. Will this keep both the hot and cold pipes from freezing between the fixture and the water heater? (my water inlet is fortunate by the water heater)
