Error Err06 or FAN ERROR indicates the integrated blower/fan is not functioning correctly. This applies to towel rails with a boost fan feature. Clean the filter if applicable and check that the fan grille is not blocked. If the fan is not spinning, contact a qualified engineer.

How does the electronic thermostat work on Thermor radiators?

Thermor's electronic thermostat uses a sensor that permanently measures room temperature and transmits values to an electronic controller. The thermostat controls the heating element's working time to reach but not exceed your set temperature, with high precision of ±0.5°C.

Why does my Thermor heat pump water heater make noise?

Heat pump water heaters produce operational noise from the integrated heat pump compressor and ventilation fan during heating cycles. This is normal operation. Thermor recommends installing these units in non-habitable spaces such as a utility room, garage, or cellar rather than near living areas or bedrooms.

How much energy can I save with a heat pump water heater compared to a traditional electric model?

A heat pump water heater can reduce your hot water energy costs by up to 75% compared to a traditional electric water heater. The electricity consumption is approximately three times lower because the heat pump extracts energy from ambient air rather than generating heat directly from electricity.

How do I clean the evaporator on my Thermor heat pump water heater?

The evaporator should be cleaned annually. Use compressed air to blow debris from the fins, a vacuum cleaner with a soft brush attachment, or a dedicated evaporator cleaning spray. Take care as the aluminium fins are sharp. Always disconnect electrical power before performing any maintenance.

What are the installation requirements for an ambient air heat pump water heater?

An ambient air heat pump water heater must be installed in an unheated, non-habitable, frost-free room with a minimum volume of 20 cubic metres. The room temperature should remain between 5°C and 35°C throughout the year. Suitable locations include garages, utility rooms, or cellars.
