Factors to consider when purchasing a low-consumption electric heater
It's important to consider several key factors to determine what you really need for your home. The power will depend on the size of the room ; the intended use; the room you want to heat (if it's a bathroom, it should have special protection); whether you want to take it on trips (in that case, it's recommended that it be small and portable), etc. There are many heaters, and several important things we recommend you keep in mind.
Consumption
To achieve maximum energy efficiency , you need to use your electric heater correctly to avoid wasting energy.
First of all, the heater must heat a room of adequate size for its power . If you use too much of the maximum power to heat a very large room, you'll consume much more. The higher the power, the higher the consumption.
It's recommended that the heaters have adequate insulation , and that doors and windows be closed to prevent the hot air coming from the heater from being wasted or escaping. It's also important that they have a thermostat that switches on when the desired temperature is reached.
In addition, to extend the life of the heater, it is important to maintain it properly , clean the filters, and wipe off the dust with a damp cloth.
The energy consumption of electric heaters will depend largely on the model, the power you use , and the length of time you leave it on.
To calculate consumption, you usually multiply the number of watts by the number of hours. Divide this result by 1,000 to get the kWh consumption.
Once you have this data, multiply it by the current rate and its taxes, and you'll know the final consumption.
Power
Power is always one of the most important factors to consider. It is determined by the space we want to heat and the timeframe in which we want to heat it.
If we buy a heater with a power that isn't suitable for the room, it will result in unnecessary higher consumption, or we won't be able to heat the space properly.
The trick to calculating the necessary power is simple: to heat 1m2 approximately 80W are needed .
Low-consumption electric heaters are usually very efficient and quickly heat the space. However, if you really need to heat the room, increase the power slightly to 80W per m2.
Size
The size of the heater also depends on the power you need.
The smallest, or mini, heaters heat small rooms very efficiently . If you want to heat a large living room , you'll need a large, powerful one.
Calculate the space where you want to place it, and keep in mind that there are very useful and manageable portable models. You can also opt for a wall-mounted heater with a tilting flap.
IP protection
If you're going to use a low-consumption heater in the bathroom, keep in mind that it must have IP protection, although most have IP22 resistance, which makes them resistant to water splashes.
You should make sure that it has at least IP24 protection , meaning it is water and dust resistant.
Low-consumption bathroom heaters are very efficient because they heat the space very quickly, allowing you to enjoy your shower in comfort.
We recommend setting aside a space in the bathroom away from water and towels for your heater. Low-consumption wall-mounted heaters are very practical; they don't get in the way and prevent any accidents.
In the bathroom, a fan heater can be a good option, especially ceramic heaters , as they are very efficient, and infrared heaters.
Differences between a low-consumption heater and a low-consumption radiator
Differences between a heater and a radiator:
Duration of heat
The heater produces instant, rapid heat. You can have your room warm in no time. On the other hand, the radiator takes longer to heat up.
When the radiator is turned off, it continues to emit heat for a while, unlike the heater, which immediately stops emitting heat when it is turned off.
Temperature
The heater typically reaches a maximum temperature of between 35° and 60°. In fact, they have a safety system that shuts off the heater if it reaches a certain temperature.
The radiator reaches a higher temperature, reaching 70°C and above. In fact, the water inside the radiator reaches up to 90°C.
Operation and autonomy
A heater is an electrical device. To produce thermal energy, it requires electricity, and it uses this electrical resistance to provide heat.
The heater creates and expels its own heat. It has an emitter to exchange heat and a fan to move the steam.
A radiator is a device that transmits heat energy from a heat transfer medium (a liquid substance that is heated). Although the heat transfer process appears to be the same—convection and radiation—their sources are often different.
The radiator emits the heat it has received from another heat generator. It's a cycle, a constant feedback loop.
