Optimal Wire Size for Installing a Bathroom Heater: A Guide

When installing a bathroom heater (bathhouse), there are many styles and varying electrical power ratings. So, what size wire should be used for a bathroom heater? And what are the usage precautions for a bathroom heater?

Size of the wire for bathroom heaters

For ordinary users, a wire gauge of 2.5 square millimeters is sufficient for bathroom heaters. However, special cases may require different considerations based on user needs. For example, if the power rating of the heater exceeds 1100 watts, a 4 square millimeter wire should be used, along with a waterproof line. It's essential to consult with a qualified electrician to determine the appropriate wire size based on the specific model and specifications of the heater being installed.

Usage precautions for bathroom heaters

1. In winter, many people tend to use bathroom heaters while showering. Most bathroom heaters rely on infrared lights for heating. Infrared rays can provide therapeutic benefits and can also be used for decorative lighting. Since most bathrooms are relatively small, heaters are typically installed above the shower area. While they provide quick warmth when showering, there are also safety risks. If you stay too close to the heater for too long, the infrared radiation can cause skin harm. For safety, it’s advisable not to spend too much time in the shower while using the heater.

2. When using a bathroom heater, it’s best to turn on the exhaust fan. This helps to expel steam, preventing the heater's metal components from becoming conductive and causing a short circuit. It also helps to eliminate humidity, ensuring fresher air and preventing oxygen deficiency while showering. Apart from the exhaust fan in the heater itself, installing an additional exhaust fan in the bathroom can further enhance air quality.

3. While using the heater, avoid constantly turning it on and off. The steam generated during a shower, combined with frequent switching, can lead to switch wear and tear. Additionally, avoid touching the heater directly to prevent electric shock, burns, and other hazards. After using the heater, it’s important to not turn it off immediately but instead allow the humidity to dissipate before turning it off, ensuring proper ventilation and drying in the bathroom. This will prolong the heater’s lifespan.
