The use environment of the integrated electrical appliance is in a relatively humid bathroom, so the safety performance of the integrated electrical appliance is higher. When purchasing, it is necessary to polish the eyes and carefully compare. GELAN Xiaobian has five shopping tips to share with everyone:

Tip 1: Look for the "3C" certification mark

The so-called "3C" certified products are products of national mandatory safety certification. According to the national 3C certification regulations, each type of Yuba product should have 3C certification and obtain relevant certificates.

Tip 2: Check the packaging accessories

Observe the appearance of the product packaging with or without scratches. The printing of the package should be clear, and the appearance and packaging of the counterfeit products should be rough. The product should be accompanied by a switch board, junction box and exhaust vent. Instructions, product certifications and safety guidelines should be included in the product packaging.

Tip 3: Power up test run

Before purchasing, please ask the clerk to test the product and see if the product function switch is working normally, whether the heating effect is obvious, whether the lighting and ventilation are normal, and whether there is no jitter or noise.

Tip 4: The central part of the bathroom that Yuba should install

Many homes install it above the bath or shower, so the surface looks hot in the winter but there are security risks. The right approach should be to install the Yuba in the center of the top of the bathroom, or slightly closer to the bathtub, so that it is both safe and functional.

Tip 5: Yuba installation should not be too low

When installing Yuba, it is best not to be too close to the top of the head. In theory, it should be above 40 cm, so as to ensure that the skin is warmed and not burned.
