DEVIhotwatt™ 45 (B) / 55 (B) / 70 (B)

The DEVIhotwatt™ is a self-limiting heating cable that is used for temperature maintenance of hot water supply and other fluids that need to maintain a certain temperature.

The self-limiting capability of the cable ensures that the output of the cable increase or decrease according to ambient temperature.

DEVIhotwatt™ ensures hot water in all taps and savings when circulation of the whole pipe system is unnecessary. All self-limiting heating cables must be over-temperature protected by a thermostat, as the output will decrease, but never be zero, and be protected by a RCD with a maximum trip current of 30 mA.

The cable is not approved for use in drinking water. DEVIhotwatt™ cables have an EPD declaration, which is a document used to transparently communicate the quantified environmental impacts of a product over its life cycle stages.
