What does the 23 error mean on an Immergas boiler?

The 23 error on an Immergas boiler indicates a return temperature probe anomaly. The NTC temperature sensor measuring return water 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 important for efficient boiler operation and protection against overheating.

What does the 46 error mean on an Immergas boiler?

The 46 error on an Immergas boiler indicates the low temperature safety thermostat has activated. This optional safety feature has detected temperature conditions outside normal parameters. Switch off the boiler at the electrical supply. Allow the boiler to return to normal operating conditions. Press the reset button once. If normal conditions are restored, the boiler should resume operation. If the error persists, contact a qualified technician for thermostat inspection.

What does the 202 error mean on an Immergas heat pump?

The 202 error on an Immergas heat pump indicates a sustained communication error between the control kit and outdoor unit lasting more than three minutes. Switch off the heat pump at the isolator switch for five minutes. Switch back on and monitor for the error. If communication is not restored, contact a qualified technician. Do not repeatedly reset the unit as this will not resolve a wiring or component fault.

What does the 221 error mean on an Immergas heat pump?

The 221 error on an Immergas heat pump indicates an outdoor unit temperature sensor malfunction. The temperature sensor on the outdoor unit is reporting incorrect readings or has failed. Switch off the heat pump at the isolator switch for five minutes. Switch back on and monitor for the error. If the error persists, contact a qualified technician for sensor testing and replacement.

What does the 20 error mean on an Immergas boiler?

The 20 error on an Immergas boiler indicates a parasite flame block. The flame detection system is sensing a flame signal when the boiler should not be firing, which could indicate a leak in the detection circuit or a flame control unit anomaly. If you smell gas, do not operate any switches, ventilate the area if safe to do so, leave the property immediately, and call the gas emergency service from outside. If there is no gas smell, switch off the boiler at the electrical supply and do not attempt to restart. Contact a Gas Safe registered engineer immediately for inspection.

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.

What COP (efficiency) can I expect from my Immergas heat pump?

The Coefficient of Performance varies by model and operating conditions. For example, the Audax Top 6 ErP achieves approximately 4.28 COP when producing water at 35°C, meaning it delivers about 4.28 kW of heat for every 1 kW of electricity consumed.

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 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.
