Quick Answer

No hot water from a combi boiler is usually a failed diverter valve, flow sensor, or a scaled plate heat exchanger; on a system boiler it can be the cylinder, pump or controls. BoilerPart.ca diagnoses the exact cause and repairs it with genuine parts across Greater Vancouver.

No hot water while heating still works (or vice-versa) tells us a lot about the cause. The fix depends on whether you have a combi boiler or a cylinder/tank system.

What you’re noticing

Cold water at hot taps
Heating works but no hot water
Hot water only briefly
No response when a hot tap opens

Common causes

  • Failed diverter valve (combi)
  • Faulty flow sensor not triggering the burner
  • Scaled plate heat exchanger
  • Cylinder/immersion or pump fault (system)
  • Control fault

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 whether heating still works (helps pinpoint the cause)
Confirm boiler pressure is normal
Make sure isolation valves are open
