When renovating a bathroom, it is common to leave space for an exhaust outlet for the heating lamp. So, when drilling, what size should the exhaust outlet for the heating lamp be—83mm or 100mm? Here’s a brief introduction.

Exploring the Differences Between 83mm and 100mm Exhaust Vents

1. According to experts from Qijia.com, the size of the exhaust outlet for the heating lamp is not fixed; it should be determined based on the size of the exhaust fan’s duct. Common sizes for exhaust outlets include 75mm, 80mm, 100mm, etc. The heating lamp is a small appliance that integrates heating, ventilation, and other functions, solving the issue of cold and heat during showers in autumn and winter.

2. Bathing lamps can be classified based on their heating principles into bulb series heating lamps, PTC series heating lamps, and far infrared heating lamps. The bulb series has a good cost-performance ratio and heating efficiency, but it poses safety issues such as the risk of strong light injuring the eyes. The PTC series heating lamps feature high safety performance and provide a wide and even heat distribution, but they are generally more expensive and take longer to heat up.

3. There are many brands of heating lamps in the market, and it is advisable to choose products from well-known and strong manufacturers locally. Generally, big brand products guarantee better quality and after-sales service. Some well-known brands in the market include Mingzu, Aupu, Midea, Panasonic, Feidiao, NVC, and Gran Electric.

4. When selecting a heating lamp, it is also important to consider the product's performance. For instance, you should check whether the product's exterior is fine and smooth, and identify what additional functions the heating lamp offers aside from heating, as the functions are becoming increasingly diverse. Since the heating lamp is installed in the bathroom, it’s essential to pay attention to the product's waterproof performance and whether it has safety measures such as explosion-proof and radiation protection.

In summary：concerning the exhaust outlet size for the heating lamp—whether 83mm or 100mm—the size should be determined based on the hose size of the heating lamp. I hope this article helps you gain a better understanding.
