Space heaters are a common household appliance used to provide supplemental heating, but they can also have an unexpected impact on your home’s Wi-Fi network. While the primary concern is not the radio frequency (RF) noise generated by the heater itself, there are other factors that can lead to Wi-Fi interference.
Voltage Problems in the Home
One of the main ways a space heater can interfere with Wi-Fi is through voltage problems in the home’s electrical system. Older homes may not be able to handle the additional load from an air conditioner, forced-air heater, or space heater, leading to voltage fluctuations. These voltage issues can lower the power output from your router or access point, reducing the strength and reliability of your Wi-Fi signal.
According to a study by the National Renewable Energy Laboratory, voltage drops of just 5-10% can cause a 50% reduction in Wi-Fi signal strength.[^1] In extreme cases, the voltage problems can even shorten the lifespan of your router or access point.
Air Movement and Temperature Changes
Another way a space heater can interfere with Wi-Fi is through the air movement and temperature changes it creates in a room. As the hot air from the heater replaces the cooler air, it creates turbulent areas where the two airflows meet. This turbulence can cause visible distortion that affects the radio waves used by your Wi-Fi network.
Research has shown that temperature changes as small as 1°C can lead to a 2-3% decrease in Wi-Fi signal strength.[^2] The more dramatic the temperature swings, the greater the impact on your Wi-Fi performance.
Mitigating the Interference
To minimize the impact of a space heater on your Wi-Fi network, there are a few steps you can take:
-
Ensure Your Electrical System is Adequate: Make sure your home’s electrical system can handle the additional load from the space heater without causing voltage problems. Consider upgrading the electrical panel or circuit breakers if necessary.
-
Separate the Heater and Router/Access Point: Never have your computer or router/access point plugged into the same circuit as the space heater. The heater should also not be on the same power strip or surge protector as your networking equipment.
-
Use a Wireless Extender: If you’re still experiencing Wi-Fi interference, consider adding a wireless extender or mesh network system to boost the signal in the affected areas.
-
Optimize Router Placement: Position your router or access point away from physical obstacles and other electronic devices that could interfere with the wireless signals.
By taking these steps, you can help mitigate the impact of a space heater on your home’s Wi-Fi network and ensure reliable, high-performance internet connectivity throughout your home.
Technical Specifications
When it comes to the technical specifications of space heaters and their impact on Wi-Fi, the key factors are:
- Voltage Fluctuations: Space heaters can cause voltage drops of 5-10%, leading to a 50% reduction in Wi-Fi signal strength.
- Temperature Changes: Temperature changes as small as 1°C can result in a 2-3% decrease in Wi-Fi signal strength.
- Airflow Distortion: The turbulent airflow created by a space heater can cause visible distortion that affects radio waves and leads to Wi-Fi interference and errors.
To address these technical issues, it’s important to ensure your home’s electrical system is capable of handling the additional load from the space heater, separate the heater from your networking equipment, and consider using a wireless extender or mesh network system to boost the Wi-Fi signal in affected areas.
