What does the 03 error mean on an Immergas boiler?

The 03 error on an Immergas boiler indicates the flue safety thermostat has activated due to excessive flue gas temperature. This is a critical safety feature detecting potential flue obstruction or combustion problems. Do not attempt to reset or override this safety feature. Do not use the boiler. Ensure the room is well ventilated. Contact a Gas Safe registered engineer immediately as flue problems can lead to carbon monoxide exposure, which is potentially fatal. Do not delay professional inspection.

How do I reset my Immergas boiler?

Locate the reset button on your boiler's control panel, typically marked with a flame symbol or the word Reset. Press the button firmly. On most Immergas models, holding the button for approximately 5 seconds will initiate a restart. If the error clears, the boiler should resume normal operation. If the boiler does not reset or the same error returns, do not repeatedly press the reset button. Contact a qualified technician for diagnosis.

What temperature should I set for domestic hot water on my Immergas boiler?

For domestic hot water, a temperature setting between 50°C and 60°C is typically comfortable for showers and baths while remaining safe. The boiler allows adjustment through the control panel using the dial or button marked with a tap symbol.

What should I do if I smell gas near my Immergas boiler?

If you smell gas, do not operate any electrical switches, lights, or the boiler controls. Do not use any naked flames or electronic devices. Open windows and doors to ventilate the area only if it is safe to do so. Do not attempt to locate the source of the leak. Leave the property immediately and take all occupants with you. Once safely outside, call the gas emergency service. Do not re-enter the property until it has been checked and declared safe by a Gas Safe registered engineer.

How do I switch my Immergas boiler between summer and winter mode?

Use the mode selector on the control panel or remote control to switch between modes. In summer mode, the boiler provides domestic hot water only and central heating is disabled. In winter mode, both domestic hot water and central heating are enabled. If using a CAR remote control, turn the main selector to the desired position. The display will show the current mode. Some models use icons: a sun or umbrella symbol for summer mode and a snowflake symbol for winter mode.

Why are some radiators not heating up when my Immergas boiler is running?

If some radiators remain cold while the boiler is running, trapped air may be the cause. Bleed each cold radiator using a radiator key by opening the bleed valve until water flows steadily, then close it. Ensure all radiator valves are open. Check that the system pressure is between 1.0 and 1.5 bar after bleeding. If radiators remain cold after bleeding, or if multiple radiators are affected, contact a qualified technician as there may be a circulation pump fault or system blockage.
