Can You Connect a Bathroom Heater to the Lighting Circuit?

When it comes to bathroom heaters, known as yùbà, many people are familiar with their function of providing warmth for bathing. So, can a bathroom heater be connected to a lighting circuit? What should be noted during the installation of a bathroom heater? Let's take a look!

Can a bathroom heater be connected to a lighting circuit?

It is not recommended because lighting circuits are designed for lower power and have thinner wiring. A bathroom heater typically has a high power rating, and connecting it to a lighting circuit can lead to overheating of the circuit, posing risks of short circuits or damage to the wiring. Additionally, if the circuit breaker has a low capacity, it may frequently trip. It is better to remove the heater's trial line and connect it to the reserved line for the lighting circuit.

The reserved lighting lines depend on the type of switch used for the heater. For a standard switch, it may require 5-6 wires, while a wireless remote control switch or smart touch switch only needs 2 wires: one for power and one for signal.

What should be noted during the installation of a bathroom heater?

1. First, the electrical wiring for the heater should be done according to regulations. Since the power can reach 1100W or more, waterproof wire should be used, with a copper core no less than 1mm. All power lines should be concealed in conduits within the walls and should not be exposed. Additionally, the switch for the heater should also be waterproof, especially in older bathrooms.

2. Secondly, the thickness of the heater should not be excessive; generally, about 20 cm is ideal. Since it is installed on the ceiling, a thicker design can complicate installation. It is advisable to install a layer of PVC ceiling on top to ensure that the back of the heater can be safely secured between the two ceilings.

3. The heater should be installed in the center of the bathroom and should not be placed directly above the bathtub. Although this may promote faster heating, it also poses significant safety risks. Rapid infrared heating can cause burns if the heater is too close to the body. Therefore, installing it in the center of the bathroom is safer and more effective for warmth.

4. When using the heater, avoid spraying water directly on it. Although most bathroom heaters are water-resistant, the internal components are not designed for direct exposure to water and may pose electrical hazards, leading to short circuits.

In summary：the above information covers whether a bathroom heater can be connected to a lighting circuit and what to consider during its installation. I hope this information can help those in need. If you want to learn more about related topics in the future, please feel free to follow our website.
