IBC Boiler Not Heating? Troubleshooting Guide

If your IBC boiler is not heating, work through this 5-minute check: thermostat calling → power on → gas on → pressure 12–15 psi → fault code on display → one reset. If heat does not return — or the code comes back — call (604) 359-1081; same-day response across Greater Vancouver.

The safe 5-minute check

1. Thermostat: set to heat, above room temperature.
2. Power: switch and breaker on; display lit.
3. Gas: valve handle in line with the pipe.
4. Pressure: ~12–15 psi cold — top up once if just below; repeated drops = leak.
5. Code: note it, then reset once only.

Symptom pointers

• Radiators cold at top — air; recurring air means a fault.
• Some rooms cold — zone valve or circulator on that loop.
• Fires then stops — short cycling: condensate, circulation or controls.
• Gurgling/banging — scale or sludge; book service before it damages the heat exchanger.

Frequently asked questions

My IBC runs but the house will not warm. Why?

Often circulation (pump or zone valve), air-bound loops or controls — heat that never reaches the radiators. Quick to diagnose with instruments.

Pressure keeps dropping — keep topping up?

No — repeated loss means a leak or expansion-tank fault that topping up hides while fresh water accelerates corrosion.

When is no heat an emergency?

Cold weather, vulnerable household members, pipes at risk, any gas smell or active leak — call (604) 359-1081.

Can I fix it myself?

Beyond these checks, no — gas-side and control work needs a licensed technician, and DIY voids warranty and insurance.
