How much energy does your heating consume every hour? When winter arrives and we turn on the heating, many people wonder why their energy bills skyrocket.
The reality is that although thermal comfort is essential, we do not always know the actual consumption of our heating systems.
In this article, we explain how much your heating consumes per hour, which factors influence that cost and how you can optimize it to save money without feeling cold.
How much does a conventional heating system consume per hour?
Consumption depends on the type of heating system installed in your home. Broadly speaking:
- 🔥 Natural gas boiler: Consumes between 1 kWh and 2 kWh per hour in operation.
- 🔥 Oil boiler: Usually consumes between 2 and 3 liters of heating oil per hour of use.
- 🔥 Electric heating (radiators, underfloor heating): Between 1 and 2 kWh per radiator.
- 🌬️ Heat pump or aerothermal system: Much more efficient, consuming barely 0.5 kWh per hour.
What does this mean in money?
For example, if your electricity rate is €0.18/kWh and your system consumes 2 kWh/hour, you are spending approximately €0.36 for every hour your system is switched on.
📈 It may seem small… but over the course of a month it can represent a very significant expense.
Factors that increase heating consumption
In addition to the type of system, several factors cause your heating to consume more energy:
❌ Excessive temperature settings: Keeping your home above 23°C is not only unhealthy, it increases energy consumption by 7% for each additional degree.
❌ Poor insulation: If your home loses heat quickly, the heating works longer and spends more.
❌ Poorly calibrated thermostats: Turning the temperature up all at once does not heat the house faster—it only wastes more energy.
❌ Dirty boilers or radiators: Lack of maintenance reduces efficiency by up to 30%.
❌ Deteriorated pipes: Heat losses occur before hot water even reaches the radiators.
How to optimize your consumption and save money
Saving on heating does not mean being cold. With small adjustments you can noticeably reduce your bill:
✅ Maintain the ideal temperature: Between 19°C and 21°C during the day, and 17°C at night.
✅ Bleed your radiators before every winter to improve hot water circulation.
✅ Service your boiler annually to ensure it operates efficiently.
✅ Insulate your home properly: Use weatherstripping on doors, double-glazed windows and thermal curtains.
✅ Install programmable thermostats: Adjust schedules so the heating only runs when you truly need it.
💡 Proper maintenance can save between 10% and 20% on your annual energy consumption.
