What to Do When Your Boiler Has No Heat
When your boiler stops producing heat, your home can become cold quickly. This guide walks you through the initial steps you can take safely and when to call for professional boiler service.
Immediate Steps to Take
1. Check the thermostat — ensure it is set to Heat mode with the temperature above room temperature. Replace batteries if needed. 2. Check the boiler pressure gauge — the pressure should be between 1 and 1.5 bar when cold. If low, repressurize using the filling loop according to the boiler manual. 3. Check for error codes on the display panel — note any error codes and refer to the manual or the panel label for their meaning. 4. Press the reset button once — most boilers have a reset button or sequence. Press only once. If the boiler locks out again, do not repeatedly reset.
Next Steps
5. Check the gas supply — verify other gas appliances are working and the gas valve to the boiler is open. 6. Check the circuit breaker — a tripped breaker can cut power to the boiler control board. 7. If the boiler has a frozen condensate pipe (external plastic pipe), thaw it carefully with warm water — never use boiling water. 8. If these steps do not resolve the issue, call for professional boiler service. Do not attempt internal repairs — boilers contain gas, high voltage, and pressurized water.
