After the bathroom renovation is completed, we need to install products like the bath heater. If you have purchased a bath heater yourself, how should you install it? Here’s a brief introduction to the installation process.
Your Complete Guide to DIY Bathroom Heater Installation
1. Before installing the ceiling, we should first create a ventilation opening on the wall and install a vent. One end of the ventilation duct should be fixed to the vent, while the other end should be placed near the installation location of the bath heater. When installing the ceiling panels, we need to leave a reserved space for the bath heater.
2. After purchasing the bath heater, check if the number of accessories is complete and whether there are any damages. Bath heaters usually come with a test plug; we should insert the plug to check if all functions of the bath heater can operate normally.
3. Once the bath heater passes inspection, we will remove the cover plate from the connection box. Using a screwdriver, disconnect the wires attached to the test plug. Then, according to the wiring requirements in the product manual, we'll connect the reserved wires to the corresponding terminals on the bath heater.
4. Install the clips on the four corners of the main unit of the bath heater, then place the main unit into the ceiling, connect the ventilation duct to the unit, and finally secure the unit to the ceiling framework.
5. Connect the wiring from the panel to the electrical connection on the main unit, then attach the panel firmly to the main unit.
6. After installing the warm air bath heater, connect the wire for the bath heater switch and secure the switch to the wall.
Things to Pay Attention to While Installing the Bath Heater
Before installing the bath heater, it is important to determine the size and type of the heater in advance. We should reserve the electrical wires and cutout dimensions according to the size and type of the heater. The ventilation duct can be pre-installed; it would be more troublesome to install the ventilation duct after the ceiling is completed. Since there are multiple wires involved with the bath heater, we must follow the manual during installation to avoid miswiring and other issues.
In summary:this is a simple guide on how to install a bath heater after purchasing it. I hope this article provides some reference and assistance for your future installation.
