Quick Answer

When you have hot water but no heating, the burner clearly works — so the cause is usually a stuck diverter valve, a failed circulator pump, low pressure, or a control/thermostat fault on the heating side. BoilerPart.ca repairs it with genuine parts across Greater Vancouver.

Hot water working while heating fails proves the boiler can fire — the problem is on the central-heating circuit, not combustion.

What you’re noticing

Hot taps fine but radiators cold
Heating won’t come on
House cold despite working hot water

Common causes

  • Stuck diverter valve (combi)
  • Failed circulator pump
  • Low system pressure
  • Thermostat/control not calling for heat
  • Stuck zone valve

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.

Confirm the thermostat is calling for heat
Check the pressure gauge is in the normal band
Note whether radiators are completely cold
Note any error code
