Reversible AC for Winter Heating in Luxembourg: Worth It?
Reversible AC = Heat Pump in Heating Mode
Every modern split air conditioner sold in Luxembourg is reversible: cooling in summer, heating in winter. In heating mode it behaves as an air-to-air heat pump with SCOP 4–5.
What SCOP 4 Means in Plain Euros
- 1 kWh of electricity → ~4 kWh of heat delivered
- At Luxembourg's electricity price (~€0.20/kWh), heat costs €0.05 per kWh
- Gas heating costs €0.09–€0.11 per kWh (boiler + losses)
A reversible AC heats a 25 m² room for half the cost of gas.
Luxembourg-Specific Limits
- Below −7 °C outside, efficiency drops sharply — keep your gas/electric backup
- Best results in well-insulated rooms (post-2000 builds, renovated apartments)
- Pair with night setback to maximise savings

Frequently Asked Questions
Will a reversible AC replace my central heating?
In a well-insulated apartment, yes. In a poorly insulated house with cold winters down to −10 °C, treat it as a supplement, not a replacement.
Does heating mode wear out the AC faster?
No, modern compressors are designed for year-round operation. Annual maintenance is what keeps lifespan at 12–15 years.
