Electric heaters allow you to quickly supplement a too weak heating system in a building. They are also an ideal replacement in spring or autumn, when turning on the main heat source is too expensive. But how to choose the right heater for your home or industrial hall? We explain this in the article below.

Each electric heater has certain operating parameters that determine its capabilities, but also allow you to predict the costs of use. Among such data, it is worth paying attention to:
- Device power. It determines the amount of current drawn from the power grid during an hour of operation at maximum settings. At the same time, this value also determines the amount of heat emitted by the heater installed in the device. The larger and colder the room, the more power is needed to heat it.
- Tension. There are two basic types of heaters in terms of operating voltage. Smaller devices work by connecting them to a single-phase socket at home or in the office. Their rated voltage is 230 V. In the case of much more powerful heaters, three-phase installations with a voltage of 400 V are used.
- Air flow. To ensure that the heat reaches every corner of the room in a short time, fans are installed in the heaters. The air flow rate allows you to estimate the time needed to distribute heat throughout the room. As a rule, larger rooms, especially production halls, require much more flow than home models.
- Additional features. It is also worth paying attention to the additional capabilities of a given electric heater. The timer prevents you from forgetting to turn off the heater. Overheating protection works similarly. A more advanced solution may be a thermostat to regulate the device's operation. You can also find electric heaters with an air dryer or smooth power control.
The key to purchasing the optimal model is to properly determine your needs. However, electrical devices are characterized by smooth regulation of operating power - within a certain power range, the amount of heat delivered to the room can be freely set, without reducing the efficiency of the heater .
How much electricity does an electric heater use?
The efficiency of the electric heater is approximately 100%. How is this possible? The heater is a high-power resistor that limits the flow of current. The "side" effect of such throttling of electron flow is the generation of heat. While the heater is operating, no element is set in motion. Therefore, there is a clean transformation of electrical energy into thermal energy.
However, the efficiency of the entire electric heater will be slightly lower due to the need to power the fans. Their power usually ranges from a few to 100 W in the case of large devices. This is a negligible amount, ranging from 1-2%. Therefore, we can roughly say that an electric heater consumes as much electricity as it produces kilowatts of heat.
Overview of electric heaters available at the Onninen wholesaler
Do you have a building that is always too cold? They interest you electric heaters to heat the room? Check what we can offer you in our wholesale store.
We have unique Halny electric heaters with a power of 7.5 kW/N and electric heaters of 15 kW/N . These are portable models, powered by three phases, which allows for greater thermal power. They have two heating speeds, and the fan ensures the flow of up to 1,200 m³ of air during an hour of operation of the device. Thanks to this, the heat is quickly propagated throughout the room. A very useful feature is the ability to connect the heater to an external thermostat. Thanks to this, this device works perfectly as a supplement to the basic heating of the building. Both operating on one controller will heat the rooms faster, and then the heater will only turn on when the basic heating cannot cope.
All our devices also have overheating protection. So you don't have to worry about damaging the device if you forget to turn it off. It is also fire protection - a heated heater without such protection may pose a real threat. Therefore, it is better to buy safe industrial heaters from our wholesaler.
