With the rise in the price of electricity and winter, many people wonder how much an electric radiator spends every hour that I have it on, because they prefer to use an electric radiator in a specific room, instead of heating the whole house. and spend even more money. Depending on the radiator you buy, the consumption will be higher or lower, because depending on the room it is advisable to use a larger (higher consumption) or smaller (lower consumption) radiator. Next, we are going to explain how to know the consumption of these devices to heat our home.
How to know the consumption of the electric radiator
In all electric radiators we have the power (in W) at which they work, for example, there are radiators with 1,000W power, 1,500W and even 2,000W power. Depending on the room we want to heat, we will have to opt for a less powerful one (and that will consume less) or a more powerful one (that will consume more).
To calculate how much an electric radiator will consume, we simply have to look at the power at which it works and multiply it by 1h, in this way, a 2000W electric radiator that is working without interruption for 1 hour will have consumed a total of 2kWh . Consumption is always measured in kWh, because depending on the electricity rate we have, we will have to pay more or less. In this case, if we have an electricity rate where each kWh is worth €0.20, we find that the cost of having the radiator on is €0.40 per hour.
However, you must take into account some aspects when calculating consumption:
- There are 2000W radiators that allow you to activate the “Eco” mode to work with a power of 1000W, it will heat less but it will also consume half as much.
- Most modern radiators have a thermostat, as soon as the room temperature reaches the temperature indicated on the thermostat, it will automatically turn off. It will only turn on if the temperature drops below the set threshold. In these cases, the consumption of the radiator will be minimal since it will be off and only the thermostat will be activated.
Of course, the latest models of electric radiators have WiFi connectivity, which allows us to turn it on and off very easily, in addition, we can only turn it on at a certain time and for a certain time.
Let’s imagine that we have a 2000W electric radiator and the thermostat is set to 19ºC, if the radiator only needs 30 minutes of operation, and the other 30 minutes it does not work because the target temperature has been reached, the consumption will be only 1kWh (half that if the 60 minutes were on). Therefore, it is highly recommended that you have an electric radiator with a built-in thermostat, because the savings will be quite significant.
Recommended electric radiators
If you are interested in a radiator with a power of up to 2000W, with the possibility of activating the “Eco” mode to work with 1000W of power, and that has WiFi connectivity and a thermostat, this Cecotec model will allow you to save a lot of money on your bill. of the light, since it will be activated and deactivated completely automatically.
If you want an oil radiator of up to 2000W, the model that we recommend below has up to 3 power levels (800W, 1200W and 2000W), ideal to adapt it to our needs. In addition, it has an analog thermostat so that it turns off and on automatically and save as much as possible.
Finally, if you want another alternative with WiFi connectivity and compatible with Alexa and Google Assistant, this Mellerware model is very interesting. It has a maximum power of up to 1200W, although we have three different modes of operation so that the power can be lowered or raised depending on our needs. We must also take into account that it has a fully programmable application to only use it when we need it.
As you have seen, calculating the consumption of an electric radiator is quite simple, it is enough to know the power of the device and the time it is running each hour. Another option is to put a smart plug to measure the consumption of the device and thus get an idea of ​​how much we are going to pay at the end of the month. If you buy a smart plug, make sure it is 16A (up to 3500W), because there are models that only support 10A and could be quite “fair” if our radiator is 2000W.
