Is an Efficient Space Heater Worth It in France? (2026)
With electricity at €0.200 per kWh in France, the saving is too small to justify the purchase: 16.7 years to pay back if you replace a working space heater, and 13.9 years for the extra cost of the efficient model when you are replacing anyway.
An efficient space heater cuts electricity by 67%: about 900 kWh, worth €180.09 a year in France. Not for the electricity
- From
- Resistance space heater or baseboard, 1,500 W, about 1,350 kWh a year
- To
- Mini-split heat pump, seasonal COP around 3, about 450 kWh a year
- Usage
- One room, 6 hours a day through a 150-day heating season
| Scenario | You pay | Payback | Net over its life |
|---|---|---|---|
| Replace a working space heater now | €3,000 | 16.7 years | −€298.65 |
| Replacing anyway: choose the efficient one | €2,500 | 13.9 years | €201.35 |
Prices are typical figures; type your own quotes above. Net over its life is the total saving over the years it lasts minus what you pay. It ignores inflation, interest and changes in electricity prices, which is conservative while prices are rising.
Our take
For one room heated a few hours a day, the saving does not pay for an installed heat pump. The case changes when it replaces resistance heating for most of a home: several rooms like this one multiply the saving, the installation cost grows more slowly, and you gain cooling in summer.
How the two models compare
| Inefficient | Efficient | |
|---|---|---|
| Model | Resistance space heater or baseboard, 1,500 W | Mini-split heat pump, seasonal COP around 3 |
| Electricity per year | 1,350 kWh | 450 kWh |
| Cost per year here | €270.13 | €90.05 |
| Over 15 years | €4,052 | €1,351 |
Usage behind these figures: one room, 6 hours a day through a 150-day heating season. Basis: A heat pump moves 2 to 4 units of heat per unit of electricity; a resistance heater delivers exactly one. Seasonal COP of 3 assumed, for the same heat as a 1,500 W heater running 6 hours a day for 150 days. The Space Heater page prices the appliance at its own typical hours, which you can change there.
The same upgrade in other countries
| Country | Saving per year | Payback, replacing now | Payback, replacing anyway | Verdict |
|---|---|---|---|---|
| United States (average) | $165.06 | 18.2 years | 15.1 years | Not for the electricity |
| United Kingdom | £236.88 | 12.7 years | 10.6 years | Not for the electricity |
| Germany | €333.00 | 9.0 years | 7.5 years | Not for the electricity |
| France | €180.09 | 16.7 years | 13.9 years | Not for the electricity |
| Australia | A$315.00 | 9.5 years | 7.9 years | Not for the electricity |
| Canada (average) | C$126.00 | 23.8 years | 19.8 years | Not for the electricity |
Local electricity prices, with the same purchase price read in local currency, which is a simplification. The saving column is what matters: the higher the price of electricity, the faster any upgrade pays back.
