Fault Categories:

  1. The system is noisy.
  2. Hot water service is unsatisfactory.
  3. Space heating service is unsatisfactory.

Causes of a 'Noisy' System:

  • Noisy heating pump operation:
    • Check system pressure (minimum 1.0 bar when cold) and vent if needed.
    • Adjust heating system pump speed as required, maintaining a temperature difference of about 11°C.
    • If noise persists during heating mode only, check and adjust the system bypass if present.
  • Noisy electric flow boiler operation:
    • Check the flow rate through the electric boiler and adjust pump speed accordingly.
    • Ensure system pressure is at least 1.0 bar when cold and vent if necessary.
  • Noise when hot water is opened:
    • Verify system pressure (minimum 1.0 bar) and vent the pump if noisy.
    • Address water hammer issues such as loose pipework or tap washers.

Causes of 'Unsatisfactory Space Heating':

  1. Check system pressure (minimum 1.0 bar).
  2. Ensure the 3 port mixing valve is set to maximum (setting ‘4’).
  3. Verify the electric flow boiler's functionality.
  4. Confirm the space heating load does not exceed specified limits.
  5. Ensure the flow temperature is at least 70°C. If not, check the 3 port mixing valve and adjust or replace if necessary.
  6. Verify the operation and settings of the programmable room thermostat.
  7. If certain rooms are not adequately heated, increase the pump speed to establish a temperature difference of 11°C and balance the system/check TRVs if applicable.

Powerflushing/Cleaning:

  • Isolate the ElectraMate appliance from the heating system before powerflushing.
  • Always follow the manufacturer's instructions for powerflushing equipment to avoid damaging the appliance.
  • If uncertain, consult the Technical Helpline.

Additional Fault Finding:

  • Check the ACB operation as follows:
    • Switch off mains.
    • Verify/insert correct jumpers.
    • Insert specific jumper.
    • Switch on mains and follow LED indications.
    • Ensure no discharge from the Pressure Relief Safety Valve.
    • Verify correct system pressure and expansion vessel air pressure.
    • Check the pressure relief valve seat and replace if necessary.
  • Boiler overheat thermostat may trip due to various issues; check and replace faulty parts and reset manually if required.

Important Warnings:

  • Never manually manipulate safety controls. Contact manufacturers for guidance.
  • Ensure the safety of the system during any maintenance procedures to prevent damage.

By addressing these potential faults systematically, technicians can effectively troubleshoot the Gledhill Electramate 2000 12kW system, ensuring optimal performance and customer satisfaction.
