For the heating season:
Remember to set the room thermostat / radiator valve dial at around 13 °C (55 °F) / “1” (13 °C / 55 °F) for unoccupied spaces at your home.
Additionally, when you clock out at work, let all the radiators around your office area clock out. Set radiators at a lower temperature, especially the ones that are in low occupancy areas, for example, kitchens, hallways, and bathrooms.
Also remember, putting down your rolladen in the evenings not only helps keep the interior warmer, but also avoids passersby from peeking into your lit living room or other areas of your home.
