Overview
- Bathroom guidance centers on roughly 22 °C, living areas around 20 °C, bedrooms at 16–18 °C, and kitchens about 18 °C with thorough post-cooking ventilation.
- Manual thermostat stages map to approximate temperatures (1≈12 °C, 2≈16 °C, 3≈20 °C, 4≈24 °C, 5≈28 °C), and turning to the maximum does not heat rooms faster once the setpoint is reached.
- Bleed radiators that gurgle or warm unevenly to restore efficiency, as TÜV Thüringen warns trapped air can raise energy costs by up to about 15 percent.
- Check system pressure after bleeding, keep valves slightly open year-round, set about Stage 2 during absence, and call a technician if air returns or pressure issues persist.
- Avoid letting rooms drop below roughly 16 °C and limit temperature gaps between rooms to under about 5 °C; target 40–60 percent indoor humidity and ventilate promptly if moisture rises.
