What does error code Err 01 mean on a Thermor electric water heater?

Error Err 01 on Thermor Duralis models indicates the battery powering the ACI Hybrid anti-corrosion circuit is no longer effective. Wait for 2 complete off-peak heating cycles (approximately 16 hours) for the battery to fully charge. If the error persists, the thermostat assembly may need replacement.

What does error code W.52.7 mean on a Thermor Aeromax Split heat pump water heater?

Error W.52.7 indicates a general fault with the outdoor unit, typically caused by software incompatibility following a change of the interface card or outdoor unit card. A qualified engineer will need to replace or reprogram the affected cards to restore software compatibility.

What does error code Err02 mean on a Thermor electric radiator?

Error Err02 indicates the digital control or thermostat has overheated. Allow the radiator to cool down for 30 minutes before restarting. Ensure there is adequate ventilation around the control panel. If the error persists, contact a qualified engineer.

What does error code W.29 mean on a Thermor heat pump water heater?

Error W.29 indicates the compressor discharge temperature is too high, exceeding 110°C. This can be caused by a sensor drift, lack of refrigerant, compressor issues, or installation problems. Contact a qualified heating engineer to check the evaporator cleanliness, refrigerant charge, and air circulation.

What does error code W.28 mean on a Thermor heat pump water heater?

Error W.28 indicates the automatic defrost cycle is not functioning correctly. Check that airflow to the unit is not obstructed and the room temperature is within operating limits. If the error persists, contact a qualified engineer to inspect the defrost system.

Why is my Thermor towel rail not heating up?

First check the thermostat is set to the desired temperature and functioning correctly. For electric models, check the fuse in the wall switch. If the controller appears to work but no heat is produced, the heating element may have failed.

How often should I drain my Thermor electric water heater?

Ideally, drain your water heater tank once a month, or at minimum every two years in areas with hard water. This removes scale deposits from the heating element and maintains efficiency.

What should I do for short and long absences with Thermor radiators?

For absences of less than 2 hours, do not adjust the controls. For absences of 2 to 24 hours, lower the control by two positions or switch to Eco mode. For absences longer than 48 hours, use Frost Protection mode to maintain 7°C.

What is Thermor's ACI Hybrid anti-corrosion protection?

ACI Hybrid (Anti-Corrosion Integrated) is Thermor's patented system combining an indestructible titanium anode with magnesium particles. An electronic control board produces a low-intensity electrical current that uses naturally present minerals to protect the tank's enamelled walls from corrosion.

What size water heater do I need for my household?

Calculate approximately 40 to 50 litres of hot water per person per day. For a family of four, this means a 150-200 litre tank is typically suitable. Underestimating leads to cold showers, while overestimating increases energy costs from heating unnecessary water.
