What Size Should Your Bathroom Heater Exhaust Hole Be?

The bathroom heater, or "yuba," is an essential appliance in home life, greatly enhancing comfort. Let's take a look at the typical hole size for the exhaust vent of a bathroom heater.

What is the typical hole size for the bathroom heater exhaust vent?

Generally, it is either 75 cm or 80 cm. Ceiling-mounted bathroom heaters have built-in exhaust functionality. Before installation, it's necessary to pre-drill holes in the wall to facilitate later installation, and the hole size needs to correspond to the size of the heater's exhaust vent. If the exhaust vent is 75 cm, the hole size should be 80 cm. Conversely, if the exhaust vent is 80 cm, the hole size should be 100 cm.

What is the installation process for a bathroom heater?

1. When the bathroom heater is delivered, you should check for any quality issues and ensure all parts and accessories are complete for timely replacements. Next, measure the size of the exhaust vent on the heater, mark the installation wall, and drill holes of the appropriate size.

2. Once the exhaust hole is drilled, you'll need to connect the exhaust duct. This involves extending one section of the duct towards the vent window, reaching the exterior wall's outlet. After completing this work, use cement to seal the hole to prevent rainwater from penetrating indoors.

3. Proper installation of the bathroom heater is also necessary. You'll want to determine the height for installation, typically around 2.3 meters, to facilitate use and minimize safety risks. Once the location is determined, connect the electrical wiring and remove the light bulbs from the heater.

4. Following this, connect the heater's various lines according to the instruction manual, insert the cover into the corresponding slot, and secure it with springs before re-installing the light bulbs. Finally, turn on the power to check if it operates correctly, which indicates successful installation.

In summary：we've shared the typical hole size for a bathroom heater exhaust vent and the installation process. We hope this information is helpful. It's essential that the exhaust hole is drilled according to specifications to avoid mismatched sizes, which could complicate the installation and cause unnecessary issues.
