Boiler problem with frozen pipes
Get a heat trace wire (like the ones used to keep gutters from freezing) and tape it to the bottom of the piping in the area where it freezes. Then cover the pipe with insulation. The cable is self-regulating and will stay at about 80 deg, which means it won't draw current when the heat is on. And good luck with your job search.
