Automation

What should I automate with a smart thermostat?

Short answer

Set a daily schedule: at most 19 °C when you are home, 15 °C at night with a gas boiler, and 10 °C when you are away for a few days. With a heat pump, smaller steps.

Explanation

A smart thermostat does not save energy by itself. It mainly helps you keep good habits: lower when nobody is home, lower at night, and warming up in time. With a heat pump a steady schedule works best.

Rules of thumb

• Gas boiler: 19 °C at home, 15 °C at night, 10 °C when away for several days. [SW-S44]
• Heat pump: 19 °C, night setback 0–2 °C depending on insulation, 15 °C when away for long. [SW-S45]
• Link it to the P1 port of the digital meter to track consumption (Flanders). [SW-S68]

Pitfalls

• A 'smart' schedule that makes the heat pump warm up fast every morning can use more than a constant temperature. [SW-S45]
