Thermor Appliance Repair in Northgate & West Green

What does error code W.50.1 mean on a Thermor Aeromax Split heat pump water heater?

Error W.50.1 indicates a communication failure in the split system. Check that the outdoor unit is receiving proper electrical power. A qualified engineer should inspect the interconnection wiring and communication cables between the indoor and outdoor units.

What does error code Err06 or FAN ERROR mean on a Thermor electric radiator?

Error Err06 or FAN ERROR indicates the blower/fan is not functioning correctly. This only appears on models with integrated fans. Check that the filter is clean and airflow is not obstructed. If the fan is not spinning, contact a qualified engineer for inspection.

What does error code W.25 mean on a Thermor heat pump water heater?

Error W.25 indicates a power supply or compressor operation fault. Check that the room is adequately ventilated and nothing is obstructing airflow. Switch off the water heater for 15 minutes, then restart. If the error persists, contact a qualified heating engineer.

What does error code 3 or W.23 mean on a Thermor electric water heater?

Error 3, W.3 or W.23 indicates a water temperature control fault related to a temperature sensor anomaly. This stops heating to prevent abnormal temperature rises. Restart by cutting power for 30 seconds. If the error persists, a qualified engineer needs to inspect the temperature sensor.

What does error code W.11 mean on a Thermor heat pump water heater?

Error W.11 means the thermodynamic water heater has not received the off-peak hours impulse from your electricity meter. Check that your off-peak hours contactor is functioning correctly and verify the wiring between your meter and the water heater.

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.

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 temperature should I set my Thermor electric radiator to?

The recommended temperature for living areas is 19°C, and for baby rooms 18°C. The Comfort temperature can be set from 12°C to 28°C on most models. For bedrooms, a slightly lower temperature of 16-17°C is often more comfortable for sleeping.

What size circuit breaker do I need for electric radiators?

A 16A circuit breaker protects installations up to 3500W using 1.5mm² cables. A 20A circuit breaker protects up to 4500W using 2.5mm² cables. For practical purposes, limit each circuit to a cumulative maximum of 4500W (typically 2-4 radiators) to minimise disruption if maintenance is required.

How do I maintain my Thermor heat pump water heater?

Thermor recommends three essential maintenance steps: operate the pressure relief valve monthly to prevent jamming from scale deposits, drain the tank at least every two years in hard water areas to remove mineral buildup from the heating element, and inspect electrical connections and thermostats for proper functioning.
