What does the 24 error mean on an Immergas boiler?

The 24 error on an Immergas boiler indicates a push button control panel anomaly. The main circuit board has detected a fault with the user control panel. Switch off the boiler at the electrical supply. Wait 30 seconds and switch back on to reset. If normal conditions are restored, the boiler should restart automatically without requiring a manual reset. If the error persists, contact a qualified technician for control panel diagnosis.

What does the 29 error mean on an Immergas boiler?

The 29 error on an Immergas boiler indicates a flue temperature probe anomaly. The sensor measuring flue gas temperature is reporting incorrect readings or has failed. Switch off the boiler at the electrical supply. Wait 30 seconds and switch back on to reset. If the error persists, contact a qualified technician for probe testing and replacement. This sensor is critical for combustion safety monitoring.

What does the 15 error mean on an Immergas boiler?

The 15 error on an Immergas boiler indicates a configuration error. The control board has detected an electrical wiring anomaly or an incompatibility in the system configuration. The boiler will not start until this is resolved. Switch off the boiler at the electrical supply. Do not attempt to reset or reconfigure the boiler yourself. Contact a qualified technician to diagnose the wiring fault and correct the configuration settings.

What does the 201 error mean on an Immergas heat pump?

The 201 error on an Immergas heat pump indicates a communication coupling error between the control kit and outdoor unit. The units are not communicating correctly during the connection handshake. Switch off the heat pump at the isolator switch for five minutes. Switch back on and allow the system to restart. If the error persists, contact a qualified technician to diagnose the communication fault and check control wiring.

What does the 08 error mean on an Immergas boiler?

The 08 error on an Immergas boiler indicates the maximum number of reset attempts has been exceeded. The boiler has been reset more than five times consecutively and has entered a protective lockout state. The reset function will be inhibited for a minimum of one hour. Do not attempt further resets during this period. After the lockout period expires, investigate the underlying cause of the original fault before resetting. If the boiler continues to require frequent resets, contact a qualified technician for diagnosis.

What annual maintenance does my Immergas boiler require?

Annual maintenance should include cleaning the heat exchanger on the fume side, cleaning the main burner, verifying correct ignition and operation, and checking burner settings for both heating and hot water phases. A visual inspection for leaks and corrosion is also required.

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.

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 does my Immergas boiler keep losing pressure?

Frequent pressure loss typically indicates a problem that requires professional diagnosis. Common causes include small leaks in the heating system pipework or radiator valves, a faulty pressure relief valve, or a problem with the expansion vessel. If you need to repressurise more than once every few months, contact a qualified technician to identify and repair the underlying cause. Do not ignore persistent pressure loss as it can lead to boiler damage or system failure.

What is weather compensation on my Immergas heat pump?

Weather compensation automatically adjusts the flow temperature based on outdoor conditions. When it is colder outside, the system increases the water temperature to provide more heat. When it is warmer, the temperature is reduced to save energy. The system uses an outdoor temperature sensor to monitor conditions. This feature improves efficiency by preventing the heat pump from working harder than necessary. The heating curve settings are typically configured by your installer to suit your home.
