Kermi Appliance Repair in Langley Green & Tushmore

What does the Al054 error mean on a Kermi x-change dynamic heat pump?

The Al054 error indicates that the dew point monitor in one of the heating circuits has triggered. Check the affected heating circuit. Review the system's cooling operation settings. Contact a technician to inspect the dew point protection settings.

What does Error 5 mean on a Kermi x-change fresh heat pump?

Error 5 indicates that the pressure switch has triggered for the first time. LED 3 shows red. The compressor shuts down but will attempt an automatic restart after 5 minutes. If the error recurs, contact a technician to check the refrigerant system pressure.

What does Error 10 mean on a Kermi x-change fresh heat pump?

Error 10 indicates that the target temperature for the legionella protection function has not been achieved. LED 3 and LED 4 both show red. Check that the electric heater backup is enabled and functioning. Verify the hot water temperature settings. Contact a technician if the system repeatedly fails to reach the required temperature.

What does the Al030 error mean on a Kermi x-change dynamic heat pump?

The Al030 error indicates that the motor has exceeded its maximum allowable temperature. The compressor motor is overheating. Perform a manual error reset. Contact a qualified technician to check the motor cooling system.

What does the Al034 error mean on a Kermi x-change dynamic heat pump?

The Al034 error indicates that one supply phase is not connected (DC bus ripple). Check the electrical supply connections. Perform a manual error reset. Contact a qualified electrician to verify Power+ electrical connections and power supply phases.

Can Kermi heat pumps be combined with solar panels?

Yes, the combination is straightforward and beneficial. Self-generated electricity from solar panels can power heat pumps sustainably. Kermi x-change dynamic models feature power-to-heat functions enabling intelligent use of photovoltaic electricity with heat storage.

Can heat pumps work in older buildings?

Yes, heat pumps are viable for older buildings as they use free environmental energy, reducing dependence on fossil fuels. Adequate insulation and compatible radiators are important to ensure efficient operation at lower temperatures.

How loud is the Kermi x-flair heat pump radiator?

The fans operate very quietly at a noise level of only around 28.5 decibels, which is quieter than a whisper. The sound-optimised design includes decoupling features that minimise noise transmission.

Can I replace a standard radiator with an x-flair heat pump radiator myself?

The physical replacement is straightforward as lug positions are identical to standard radiators, allowing existing brackets to be reused in most cases. However, the x-flair requires an electrical connection for its integrated fans, which should be installed by a qualified electrician.

What do radiator requirement classes mean?

Requirement classes describe load tolerance at installation sites. Class II applies to public areas with occasional careless use. Class III covers high-stress environments like classrooms. Class IV handles maximum requirements in specialised facilities. All Kermi fixings comply with VDI 6036 Class II as standard.
