Program the thermostat to drop to 16 °C (or lower) at night and when nobody is home, and to warm up shortly before you get up or come home.
With underfloor heating, don't drop below about 18 °C for normal absences, because it reacts slowly. Avoid letting poorly ventilated rooms fall below 10 °C, which increases the risk of condensation and mould.
Details
| Impact | Large · A day and night schedule saves about 10% of heating, which is about 1,500 kWh a year in an average Flemish house (15,000 kWh for heating). How we rate impact |
|---|---|
| CO₂ saved | About 300 kg of CO₂ a year, roughly the yearly uptake of 30 forest trees. How we count CO₂ |
| Estimated saving | ≈ 10% of heating · Day/night programme versus constant temperature (Flemish government figure). (confidence: high) |
| Who acts | You (tenant) |
| Needs landlord's agreement | No |
| Type | Action |
| Constant or subject to change | Constant · Good practice that barely changes with new laws, prices or services. |
