Do My Supply Ducts Keep My Water Pipes From Freezing?
Both my supply ducts and my water pipes run through a vented crawl space under my home. I live in Eastern Washington and outdoor temperatures normally run from zero to 20 degrees in the coldest part of winter. I plug the vents with foam plugs in Winter. My question is: Are the ducts keeping my water pipes from freezing. (Temperatures as low as 25 below have been known here). I have foam lagging on hot water pipes and use a recirculating pump because it takes about 7 minutes to get hot water to the kitchen otherwise. Is there someting I can do to make this system more energy efficient? I also have a problem with a hose bib that sometimes drips when on and fills one of the galvanized barriers for a vent that is under the hose bib.
