Frozen Pipes and No Heat in Winter
Frozen condensate or water pipes during cold snaps can stop your heating.
BC cold snaps can freeze the pipes your heating depends on. Here's how to respond.
What freezes
The external condensate pipe commonly freezes and locks out the boiler; exposed water pipes can also freeze and burst.
What to do
Thaw a frozen condensate pipe with warm water and reset; protect exposed pipes with insulation and keep some heat on.
Key takeaways
- Condensate pipes freeze first
- Thaw with warm water, then reset
- Insulate exposed pipes
- Keep some heat to protect plumbing
