Thermor Appliance Repair in Grange

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 Err10 mean on a Thermor electric radiator?

Error Err10 indicates a communication fault between the motherboard and thermostat control. Cut power for 2 minutes, then restart. If the error persists, contact your installer or a qualified engineer as this indicates an internal electronic fault.

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 Err02 mean on a Thermor towel rail?

Error Err02 on Thermor towel rails indicates the digital control or thermostat has overheated. Allow the towel rail to cool down completely before restarting. Ensure towels are not covering the control panel or blocking ventilation.

What does error code W.50.2 mean on a Thermor Aeromax Split heat pump water heater?

Error W.50.2 indicates a communication failure between the regulation board and interface card. Check the power supply to the outdoor unit and interface card. A qualified engineer should verify interconnection wires 1 and 2, and inspect the communication cable between the circuit boards.

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 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.

Are Thermor water heaters protected against Legionella bacteria?

Yes, all Thermor electric water heaters include anti-legionella protection. The water temperature cannot be set below 50°C, which prevents bacterial growth. Legionella bacteria thrive between 23°C and 43°C, so maintaining temperatures above 50°C eliminates this risk.

What is the difference between inertia radiator heating body materials?

Aluminium heating bodies are highly reactive, ideal for irregular schedules with variable occupancy times. Cast iron bodies offer both inertia and reactivity, suitable for mixed routines. Heat transfer fluid bodies provide steady, sustained warmth best suited for regular schedules with consistent presence times.

What should I do with my heat pump water heater during an extended absence?

For absences of less than two months, close the water inlet valve at the safety group. For absences longer than two months, close the water inlet, drain the tank completely, and ideally allow it to dry out. This prevents stagnant water issues and protects the system during extended periods without use.
