Track everything on one platform.

A digital dashboard display on a laptop, a smartphone, and a tablet. Each device shows different data, such as temperature trends over a month, steam trap data, and connectivity data.

The BOSS Portal

Data is key to optimizing heating controls. That’s why we have the BOSS Portal. 

Kelvin’s BOSS Portal is your all in one platform that provides multifaceted building heating data, breaking trends down by floor, line, and even down to individual radiators.

Use the platform to:

  • Track savings

  • Check cold unit compliance

  • Check for faulty radiators and risers

  • Monitor steam trap health

  • Analyze your building’s heating patterns

Why Kelvin? We’ll let the numbers do the talking.
