Quick Answer

If your boiler runs but there’s no heat, the most common causes are a failed circulator pump, a stuck diverter or zone valve, low system pressure, or a thermostat/control fault. BoilerPart.ca diagnoses the exact cause and repairs it with genuine parts across Greater Vancouver, same-day where possible.

A boiler that powers up but delivers no heat is one of our most common calls. The fix depends on whether the burner is firing and whether water is circulating.

What you’re noticing

Boiler on but radiators cold
Heating won’t come on
House not reaching temperature
Burner firing but no warmth

Common causes

  • Failed circulator pump — heat isn’t being moved
  • Stuck diverter/zone valve
  • Low system pressure locking out the boiler
  • Thermostat or control fault
  • Airlocked or sludged system

What you can safely check first

Beyond these safe checks, do not open the boiler or touch gas, electrical or sealed components — BC law requires a licensed gas fitter. Call us for a proper diagnosis.

Check the thermostat is set above room temperature and has power/batteries
Confirm the boiler pressure gauge is in the normal band (about 1–1.5 bar)
Make sure the boiler switch and breaker are on
Note any error code shown

When this is urgent

Treat as urgent in freezing weather or with vulnerable occupants.
