Keep Your New Furnace's Drain Line From Freezing By Rerouting It
All furnaces have a drain pipe, through which condensation that collects leaves the heater. Contractors often run these pipes outdoors through walls, which leaves them susceptible to freezing during winter in the Northern United States. While exterior drain pipes can be insulated with heat tape or foam, running the pipe through a basement floor, instead of the wall, will prevent it from freezing up. If you live in a northern state and are having your furnace replaced, ask your furnace replacement technician for information about rerouting the heater's drain pipe through your basement floor to prevent it from freezing up.
