An electric heater is not necessarily cheaper than central heating, but it can be a smart choice if you are only heating one room and keeping the rest of the house at a lower temperature. The answer depends on your gas and electricity rates, how long you use the room, and how well it is insulated. Therefore, calculate it first using your own rates.
Why is electricity per kWh more expensive than gas?
Electricity typically costs more per kWh than gas. An electric heater converts all consumed electricity into heat, so the costs per hour are easy to calculate: power in kW multiplied by your electricity rate. A central heating boiler, on the other hand, often heats the entire house or multiple rooms at once, and factors like efficiency and pipe heat loss also come into play. So, do not just compare the price per kWh, but also the amount of space you want to heat.
Calculation example for a 2000-watt heater
A 2000-watt heater consumes 2 kWh per hour on the highest setting. With an example rate of €0.30 per kWh, that costs €0.60 per hour. Three hours of use per evening would then cost €1.80. Adjust the rate to your own energy contract. On a lower setting or with a thermostat, consumption is lower. Also read how many watts does a heater consume per hour?
| Situation | Electric heater | Central heating boiler |
|---|---|---|
| Heating one room briefly | Often convenient, heats up quickly | Whole house must be heated |
| Whole house warm all day | Usually not economical | Better suited |
| Heating up a cold room quickly | Immediate heat | Takes longer |
| Poorly insulated room | Heat escapes quickly | Heat also escapes |
When is an electric heater worthwhile?
A heater is worthwhile if you turn down your central heating and only heat the room where you are, such as a home office or bedroom. See also how to quickly warm up a cold room without central heating. Use the heater safely and read where to safely place an electric heater and whether a heater can be left on all night.
Direct answer: for heating one room briefly, an electric heater can be smart; for the entire house, central heating usually remains better. Calculate it using your own rates.
