Terma Simple ONE Designer Electric Towel Rails - Blue


Terma Simple ONE designer towel rails provide independent bathroom heating with a chic aesthetic - a definitive upgrade to conventional bathroom heaters. Styled with flat geometric bars and an attractive blue finish, the Simple adds a designer accent to bathrooms, en-suites, and washrooms.

Please note: Due to the positioning of the ONE heating element, the bottom three bars of this towel rail do not heat directly and are for decorative purposes only. This does not affect the heat output of this product.

The Terma Simple provides elegant bathroom heating with convenient, basic control. Its minimalist, geometric ladder design will look a treat in any modern bathroom looking for a clean and crisp aesthetic. These versions are finished in pigeon blue, adding an attractive accent to bathrooms, washrooms, and en-suites.

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.
