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.

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 do I clean the condensate drain on my heat pump water heater?

Clean the condensate drain tube annually to prevent blockages. Use compressed air to blow through the tube, insert a small cloth attached to something rigid to clear debris, or use a small bottle brush. A blocked drain can cause water to back up into the unit and affect performance.

How often should I clean the air filter on my heat pump water heater?

Clean the air filter annually under normal conditions, or every six months if the unit is installed in a dusty environment. A clogged filter reduces heat pump efficiency and can lead to insufficient hot water production. The filter is accessible without tools and can be cleaned with a vacuum or soft brush.

What is the difference between Comfort and Eco modes on Thermor radiators?

Comfort mode maintains your set temperature when you are present (typically 19-20°C for living areas). Eco mode reduces the temperature by 3.5°C below the Comfort setting, suitable for nighttime or short absences of less than 48 hours.
