Terma Quadrus Bold ONE Designer Electric Towel Rails - Black


The Terma Quadrus Bold ONE provides statement heating for bathrooms or en-suites, with its daring design and imposing metallic black finish. Featuring an in-built, push-button interface, the Quadrus can be controlled with a few simple touches - offering independent bathroom heating and towel drying, alongside a 2-hour timer function. 

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.

Terma Quadrus Bold ONE Designer Electric Towel Rails provide statement heating for bathrooms and kitchens, with their imposing black finish, staggered rectangular bars, and modern design. For bespoke, stylish bathroom heating, the Quadrus Bold is second to none.

Quadrus Bold electric towel rails are equipped with an integrated “One” heating element which offers effortlessly simple push-button control. Push the base of the heating element once to heat at 45°C, twice to heat at 60°C, and a final time to turn the towel rail off — an LED light at the base of the element changes colour so you can tell with a quick glance what setting you’ve chosen.

Quadrus Bold towel rails also come with a timer function that can be used to set the rails to turn off after a period of 2 hours; a useful feature for warm days when you need dry towels but don’t want to heat your bathroom. Frost protection is also included to prevent your pipes from freezing when the ambient temperature drops below 6°C.
