Electric heaters allow you to quickly supplement a heating system that is too weak in a building. They are also an ideal replacement during spring or autumn, when starting the main heat source is too expensive. However, how do you choose the right heater for your home or industrial hall? We will tell you about it 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:
- Power of the device. 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 greater the power needed to heat it.
- Voltage. There are two basic types of heaters in terms of operating voltage. Smaller devices operate when connected to a single-phase socket at home or in the office. Their nominal 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. In order for the heat to reach every corner of the room in a short time, fans are installed in the heaters. The air flow rate allows us to estimate the time needed to distribute the heat throughout the room. As a rule, larger rooms, especially production halls, require a much greater flow than home models.
- Additional functions. It is also worth paying attention to the additional capabilities of a given electric heater. A timer protects against forgetting to turn the heater off. 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 regulation.
The key to buying the optimal model is to properly define your needs. However, electrical devices are characterized by smooth regulation of operating power - in a certain power range, you can freely set the amount of heat delivered to the room, without reducing the efficiency of the heater .
How much electricity does an electric heater use?
The efficiency of an 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. During the operation of the heater, no element is set in motion. Therefore, a pure transformation of electrical energy into thermal energy occurs.
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 value, within the range of 1-2%. Therefore, it can be said 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 constantly too cold? Are you interested in electric heaters to heat up 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 15 kW/N . These are portable models, powered by three-phase, which allows for greater thermal power. They have two heating speeds, and the fan provides a flow of up to 1200 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 function is the possibility of connecting the heater to an external thermostat. Thanks to this, this device works great 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 start only when the basic heating can't 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 a fire protection - a heated heater without such protection can pose a real threat. That's why it's better to buy safe industrial heaters from our wholesaler.
