Electric Heater Features

Thermostats Explained

Most electric heaters come equipped with a thermostat, which is a tool for regulating temperature. You can adjust the temperature to your preferred degree of warmth.

Timer Function

Some heaters have a timer function, allowing you to set the heater to turn on or off at specific times. This feature is handy for those who wish to have their home warmed up by the time they arrive.

Power Modes

Electric heaters often have different power modes, allowing you to choose the intensity of the heat output. These modes enable energy efficiency and help manage power consumption.

Heater Activation

Powering Up

Turning on your electric heater is typically a straightforward process. First, position the heater on a flat and stable surface, away from flammable items. Ensure the area is well-ventilated, and the heater is not in a confined or enclosed space.

After the heater is safely positioned, plug the heater cord into the electrical outlet. Make sure the plug fits securely into the outlet to ensure a stable power supply. If your heater has a power cord that can be disconnected from the unit, ensure both ends are firmly connected.

Now, locate the power switch on your heater. This is typically an easily identifiable button or switch marked with a universal power symbol or clearly labeled as “ON/OFF”. Depending on your specific heater model, you might need to flip the switch or press the button to power up the heater.

Setting the Temperature

Next, set your heater’s temperature. Most heaters are equipped with an adjustable thermostat to help you regulate the room temperature according to your personal comfort level. The thermostat usually has a dial or a digital panel that allows you to set the desired temperature.

The operation of the thermostat varies between heater models. In general, rotating the thermostat dial clockwise increases the heat setting, while rotating it counterclockwise decreases it. On heaters with a digital panel, you can press the up or down arrows or type in the desired temperature directly.

It’s worth noting that it might take a few minutes for the heater to reach the set temperature, especially in larger rooms or colder conditions. During this time, the heater will operate continuously. Once the desired temperature is achieved, the heater will cycle on and off to maintain the set temperature.

Using the Timer

If your heater has a timer function, it provides additional convenience and energy efficiency. You can program the heater to start and stop at specific times, allowing you to heat your home just when needed. This can be particularly helpful for warming up your home before you wake up in the morning or return from work in the evening.

To set the timer, locate the timer control on your heater. This could be a dial, a set of buttons, or a digital interface. Follow your heater’s specific instructions to set the timer. Typically, this involves selecting the start and end times for the heater operation.

Efficient Usage Tips

Heater Size and Room Size

The size of the heater and the size of the room it’s intended to heat are crucial factors in heating efficiency. Using a heater that is too small for a large room might result in insufficient heating, while using a large heater for a small room can lead to unnecessary energy consumption and overheating.

When selecting a heater, consider the size of the room. As a general rule, a room measuring 150 square feet would require a heater with an output of 1,500 watts. Always refer to the manufacturer’s guidelines when choosing the right size heater for your space.

Ideal Temperature Settings

Determining the ideal temperature setting for your heater is often a matter of personal preference. However, setting your heater to a comfortably low temperature can help save energy and prevent overheating.

Starting at a lower temperature setting and gradually increasing it until you find a comfortable level can be a practical approach. Remember that every degree above 20 degrees Celsius can add around 10% to your heating bill, so it’s wise to aim for a balance between comfort and energy efficiency.

Limiting Heat Loss

Preventing heat loss is key to maximizing the efficiency of your electric heater. There are several ways to limit heat loss in your home:

  • Insulation: Properly insulating your home can significantly reduce heat loss. This includes insulating walls, ceilings, and floors and using draft excluders on doors and windows.
  • Closing Doors and Windows: Keep doors and windows closed when the heater is operating to prevent warm air from escaping and cold air from entering.
  • Using Curtains or Blinds: Thick curtains or blinds can provide an extra barrier to heat loss through windows.


Despite the best efforts, you might sometimes encounter issues with your electric heater. Here are some common problems and their potential solutions.

Not Turning On

If your heater does not turn on, there could be several causes:

  • Power Supply: Check if the heater is properly plugged into the electrical outlet. Also, try a different outlet to rule out any issues with the power supply.
  • Power Switch: Check the power switch or button on the heater. Ensure it’s in the ‘ON’ position.
  • Thermostat Setting: If the thermostat is set too low, the heater might not turn on because the room temperature is already at or above the set temperature.

If you’ve checked these areas and the heater still won’t turn on, you might need professional assistance to diagnose and repair the problem.

Not Heating Up

If your heater turns on but doesn’t warm up the room, here are a few things to consider:

  • Thermostat Setting: If the thermostat is set too low, increase the temperature setting.
  • Room Size: If the heater is too small for the room size, it might struggle to heat the room effectively. In this case, you might need a larger heater.
  • Heat Loss: If there is significant heat loss in the room due to drafts or poor insulation, the heater might not be able to maintain the desired temperature.

Automatic Shutdown

Most modern heaters come with a safety feature that automatically turns off the heater if it overheats. If your heater shuts down suddenly, it might have overheated. In this case, turn off the heater and unplug it. Allow it to cool down before attempting to turn it on again. If it continues to shut down, contact a professional for assistance.
