What to consider when purchasing a bathroom heater

1. Consider bathroom size: When buying a bathroom heater, it's essential to take the size of the bathroom into account. For small bathrooms, due to limited space and high humidity levels after showering, it's necessary to choose a heater with efficient ventilation capabilities.

2. Safety considerations: Given the unique conditions of a bathroom, where moisture is prevalent, there's a risk of short circuits leading to electrical shocks. To reduce the chances of accidents, prioritize selecting a bathroom heater that is temperature-resistant and moisture-proof.

3. Eye protection: Since the light from bathroom heaters can be intense and potentially harmful to eyesight—especially for children—it's advisable to choose heaters with a frosted shell to reduce the light's impact on the human body.

Precautions when using a bathroom heater

1. During installation, ensure that the bathroom heater is more than 20 centimeters away from the top of your head. Otherwise, it could damage the skin during use, with the optimal position being directly above where you shower.

2. Do not use the heater for extended periods. Bathroom heaters emit infrared rays, which can harm people’s eyes.
