Direct water heaters are a popular choice for many households due to their ability to heat water quickly and instantly, as well as being easy to install. However, many people still have concerns about the safety of direct water heaters. Check out the following article by Mytour to learn about the 3 safety modes on direct water heaters!
1. What is a direct water heater?
A direct water heater is a device that heats water directly through an electric resistor without the need for a storage tank. When water passes through the device, it is heated directly in a short period of time and delivered straight to the faucet for use. Therefore, direct water heaters typically have high power to shorten the water heating time.
2. 3 safety modes on direct water heaters
With the direct water heating mechanism, many people are hesitant to purchase and use them due to concerns about scalding and fire hazards. However, in reality, a quality product will come with temperature control sensors, pressure control relays, or ground fault interrupter circuits to ensure safety.
Here are 3 safety modes on direct water heaters that you should consider when making a purchase:
2.1. Flow switch
The flow switch, also known as the flow control, is a component equipped to help the machine sense changes in the flow of water in the pipes. This component plays an automatic role in regulating the water flow, protecting the electrical system, and preventing the direct water heater from overheating when clogged.
In case of low water pressure, this switch will automatically cut off the power and prevent the machine from heating the water excessively to ensure safety and prevent electrical incidents.
2.2. Electrical leakage isolation mode
Most types of direct water heaters in general and direct water heating machines, in particular, are equipped with an ELCB/ELB electrical leakage breaker. This component is highly sensitive to help limit internal electrical contact incidents.
When detecting electrical leakage in the circuit, the ELCB/ELB will automatically cut off to limit unfortunate incidents. Therefore, when wanting to reuse the device, users need to switch this switch back on.
Users can check the ELCB/ELB component through the Test and Reset buttons. After installation, you activate this function and press the Test button, then press Reset and let the machine test its operation. If after 5 - 8 seconds, the water in the tap has heated, it means the anti-shock component is still functioning.
If you suddenly find the hot and cold water heater disconnected from power, it means the ELCB is warning that your home's power source is unsafe. At this time, you need to check the power source again and should not immediately turn on the machine for continued use.
Additionally, users can isolate the electrical current by adding a reservoir such as an indirect hot and cold water heater or pouring hot water into a container when it is just hot enough, then turning off the machine.
2.3. Temperature sensor
With the mechanism of heating water directly through the heating wire and leading it directly to the shower, the direct hot and cold water heater is equipped with a temperature sensor system to ensure maintaining water temperature stability at 45 - 55 degrees Celsius.

3. Safety precautions for using direct water heaters
During the use of direct water heaters, users need to pay attention to the following points to ensure safety:
- Install the direct water heater according to the manufacturer's instructions and technical standards.
- Never leave the heater on continuously 24/7; after use, immediately turn off the device.
- Regularly maintain, inspect, and clean the machine to help extend its lifespan and quickly detect any malfunctions.
- In case of malfunctions, electrical leaks, or excessive hot water, users should promptly cut off power and contact the warranty center or repair service for assistance in inspection and repair.
