Terma Simple Designer Electric Towel Rails are oil-filled and come fitted with an electrical element that includes basic in-built control features. Using its discreet ‘Heater One’ element, you can select between 45 °C and 60 °C temperature settings, as well as a 2-hour timer mode to restrict your energy usage. An anti-frost mode is also included, which will activate when ambient temperatures fall below 6 °C to prevent pipes from freezing.

The Terma Simple has an IPX5 protection rating, making it suitable for installation in bathrooms, provided it is hardwired by a professional electrician.
