The ONE heating element is a unique product in Terma's range as it allows the user to enjoy all the values associated with having an electric heating element, and at the same time does not impact on the radiator's design. The cross-section of the ONE casing can be adapted to the radiator collector, thanks to which the electric element becomes its natural extension. Moreover, the ONE casing is produced using powder-coated or chrome-plated steel, so the color of the heating element can be matched to the the color of the radiator. As a result the radiator and the heating element merge into a coherent design.
An invisible controller allows the user to set two heating temperatures. A program can also be set on the controller so that the heating element switches off after two hours. The ONE is also capable of wireless -IR communication with an external wall controller (TT-IR or DR-IT), which enhances the use of the ONE heating element with additional features.
The offer includes:
- a version of the ONE heating element with a spiral cable,
- a version with a straight cable, with or without a plug,
- and, our new option, a version with a cable without a plug and an appropriately designed cable cover.
A straight cable without a plug is connected directly to the electrical box, and the version with a cable cover allows the cable to be hidden in an aesthetic way.
The version with a cable cover is available for all cross-section types of ONE heating elements. As standard, the length of the cover is adjustable in the range from 52 mm to 70 mm.
For some models of radiators where the depth of which is greater than 70 mm, it is necessary to purchase an additional masking element which is adjustable in the range of 70-88 mm or 88-106 mm.
The table shows the models of Terma radiators that require the additional purchase of an prolonged masking element.
| The length of the additional masking element | The model of the radiator |
| 70-88 mm | Sherwood V, Sherwood V E, Retro, Ribbon V E, Dexter (width 400 mm and 500 mm), Simple DW |
| 88-106 mm | Sherwood V, Sherwood V E, Tune VWD, Tune VWD E, Triga AN E, Dexter (szer. 600) |
