Kermi Appliance Repair in Newtown and St Leonard's

What does the Al019 error mean on a Kermi x-change dynamic heat pump?

The Al019 error indicates that the electronic expansion valve actuator reports a failure. The expansion valve motor or its wiring may be defective. This error requires professional repair. Contact a qualified technician to inspect the expansion valve actuator and wiring.

What does the Al038 error mean on a Kermi x-change dynamic heat pump?

The Al038 error indicates that the frequency converter drive has been deactivated. Check that all hydraulic valves are open, clean the water filter, and bleed air from the primary circuit. Verify the external contactor has 24V supply. Contact a technician if the issue persists.

What does the Al037 error mean on a Kermi x-change dynamic heat pump?

The Al037 error indicates incorrect compressor parameter values detected during auto-tuning. Perform a manual error reset. Contact a technician to verify compressor type and motor parameters.

What does the Al013 error mean on a Kermi x-change dynamic heat pump?

The Al013 error indicates that the maximum allowable pressure threshold has been exceeded. Check that all hydraulic valves are open, clean the water filter, and verify the circulation pump is functioning. Bleed air from the primary circuit. Contact a technician if the issue persists.

What does the Al049 error mean on a Kermi x-change dynamic heat pump?

The Al049 error indicates that the maximum permissible discharge temperature has been exceeded. Check that all hydraulic valves are open. Clean the water filter. Bleed air from the primary circuit. Contact a technician to inspect the expansion valve and refrigerant levels.

What is the operating temperature range of Kermi x-change heat pumps?

The Kermi x-change dynamic pro operates in outdoor temperatures from -20°C to 40°C and can achieve flow temperatures up to 70°C. This wide operating range makes these heat pumps suitable for both new builds and older properties.

Should I replace my old radiators?

Yes, it often makes sense to replace old radiators. Outdated models frequently work inefficiently, consume more energy, and no longer provide the desired level of heating comfort. By replacing your radiators, you can significantly increase the efficiency of your heating system, reduce costs, and improve your quality of living.

What is hydraulic balancing and why is it important?

Hydraulic balancing ensures each radiator receives precisely the amount of heating water needed for efficient, even heating throughout your home. Without proper balancing, radiators near the pump may receive too much water while those further away receive too little, causing uneven heating and wasted energy.

Can Kermi heat pumps provide cooling as well as heating?

Yes, a heat pump can not only heat but also cool. In the warm months, it extracts heat from the room and releases it into the environment. This works either through panel heating systems such as underfloor or wall heating, or through special heat pump radiators.

What is a modulating heat pump?

A modulating heat pump can adjust its heating output to match the building's heat demand. This allows the heat pump to operate more quietly and efficiently compared to fixed-output models, as it avoids frequent on-off cycling.
