Our philosophy is simple. We believe that the way we use energy in the home is long-overdue a revolution. When so many areas of our lives have got better, cheaper and easier as a result of smart technology, why do we still manage our heating using clunky thermostats and impossible to understand boiler controls?

Advanced Heating Control

PassivEnergy does all the things a modern heating controller can do – and a lot more besides.
  • Optimum start turns on the heating only when it is needed, and over time it will learn when to turn it up and down to get the temperature just right, just-in-time.
  • Temperature smoothing carefully manages temperatures so your house doesn’t get too warm or too cold.
  • Weather compensation allows the system to adjust itself based on outside temperature.
  • PassivSystems’ Occupancy buttons offer an immediate ‘on/off’ override of the entire system for when people leave late or get home early.
