Boiler Warranty Guide — What Common Failures Are Covered
Published: July 21, 2026 — CANRO Heating & Cooling — Greater Vancouver, BC
Commonly Covered Failures
Heat exchanger defects (corrosion within 10-15 years), control board failures (electronic defects), gas valve malfunctions (manufacturing defects), and burner assembly defects. Coverage is typically parts only — labour is your responsibility.
Commonly Denied Claims
Failures caused by: improper installation (unlicensed installer, incorrect sizing), lack of annual maintenance (no service records), water quality issues (scale, sludge, corrosion from untreated water), power surges, and freeze damage. Keep all maintenance receipts.
Maximizing Coverage
Register your warranty within 90 days of installation. Use only licensed gas fitters for annual service. Use system inhibitor and document its annual top-up. Address error codes promptly — ignoring warnings can turn a covered repair into an uncovered replacement.
