A a boiler that leaks more or starts leaking in cold weather is one of the most common boiler leak complaints HeatLand sees across Metro Vancouver. Here is what causes it, what it means, and how we fix it – honestly.
If you see fast water loss, smell gas, or notice unusual sounds with the leak, shut off the boiler and the water supply to it immediately, then call HeatLand at (604) 330-3812. Never leave a leaking boiler running unattended.
What causes this leak
Cold weather can trigger boiler leaks by causing thermal contraction that opens small cracks in corroded fittings, by freezing condensate pipes (on condensing boilers) that cause back-pressure, or by revealing pump and seal wear after a long idle summer.
How HeatLand diagnoses and repairs it
We inspect the system for cold-weather specific failure points – condensate pipe freeze, contraction-related fitting leaks, and pump condition after summer dormancy. We also check that the condensate pipe is properly routed and insulated.
Why it matters
Cold weather is one of the most common triggers for boiler leaks appearing. If your boiler only drips in cold weather, the most likely causes are thermal contraction of corroded fittings or a condensate pipe issue.
Repair or replace?
If the leak source is a component (valve, pump, tank, fitting), repair is usually straightforward. If the boiler body or heat exchanger is leaking, replacement is typically the safer path. We advise honestly and check your rebate eligibility if replacement is needed.
