    Info Specification

    Introducing DEVIhotwatt™, a cutting-edge self-limiting heating cable designed for the efficient temperature maintenance of hot water supplies and other fluids requiring constant temperature levels. Here’s why DEVIhotwatt™ is an essential addition to your system:


    • Self-Limiting Technology: Automatically adjusts its output to match ambient temperatures, increasing when it's cold and decreasing when it's warm, ensuring your fluids are always at the perfect temperature without wasting energy.
    • Enhanced Efficiency: Provides hot water across all taps, eliminating the need for full-system circulation and leading to significant energy savings.
    • Safety First: To ensure maximum safety, all DEVIhotwatt™ cables require a thermostat for over-temperature protection, as their output can decrease but never reach zero. Additionally, they must be protected by an RCD (Residual Current Device) with a maximum trip current of 30 mA, safeguarding against potential electrical faults.
    • Application Specific: Although highly effective for temperature maintenance, it's important to note that the DEVIhotwatt™ cable is not suitable for use in drinking water.


    Opt for DEVIhotwatt™ to maintain your water and fluids at the desired temperature efficiently and safely, while also enjoying the benefits of reduced energy consumption.
