1. Safe technology for electric water heaters
Nowadays, electric water heaters come equipped with advanced and superior technologies. Along with learning about the installation of indirect and direct electric water heaters for safe use, pay attention to the criteria below.
1.1. Electric Leakage Circuit Breaker (ELCB) Sensor
The most crucial aspect of a safe electric water heater is electrical safety, and the ELCB leakage sensor is the essential feature for a shock-proof water heater.
Most genuine and safest electric water heaters are equipped with this technology, eliminating the risk of electrical leakage and reacting almost instantly when such a situation occurs.
The ELCB system is designed on the power line and can adjust the power cut within 1/1000 right after detecting electrical leakage. Currently, there are 2 types of ELCB on the market: single-pole and double-pole. The single-pole sensor can only detect one pole, while the double-pole type can sense both poles, providing enhanced safety for users.
Panasonic water heaters are equipped with ELCB electrical leakage sensors.1.2. Overheat and Burn Prevention Sensor
Hot water passes through the machine to be heated and then comes out through the pipes for users. Therefore, modern water heaters nowadays have temperature sensors to stabilize the water temperature at 45-55 degrees Celsius, controlling the heat so that the water does not become suddenly too hot, ensuring effective burn prevention and increasing safety for users.
1.3. Dry Burning Prevention Sensor
This sensor will automatically cut off power when the water temperature rises too high and the water flow through the machine is low. It will then restart when cooled, avoiding dry burning scenarios and contributing to a safer electric water heater for the family.
1.4. Flow Control, Water Flow Adjustment
All water heaters have a flow control button, regulating the water flow in use. It operates by sensing changes in flow within the pipes. When the water pressure becomes too weak, it will automatically cut off power, preventing electrical issues.
1.5. Self-diagnosis, User Warning
In every safe water heater, there is a button to signal errors, dangers, or electrical leaks to users, prompting them to call for repair services. In the shock-proof and leakage-proof system, sensors are in place. In case of incidents like electrical leaks or overloads, it automatically cuts off power. Afterward, the error button lights up, signaling users to stop using and address the issue.
1.6. Electromagnetic Compatibility (EMC) Standards
As we know, electromagnetic waves affect human health, though invisible to us. However, their impact is visible on other electronic devices, such as electromagnetic interference. Nevertheless, not every manufacturer pays attention to this aspect.
Safe and high-quality water heaters with electromagnetic compatibility (EMC) features, when operating near other electronic devices, will not cause excessive interference or affect their normal functioning. They are especially safe for human health.
Electromagnetic Compatibility (EMC) Standards2. 6 Ways to Choose a Safe Water Heater
In addition to referencing the guide for directly safe and shock-proof water heater purchase, let's explore 6 criteria to 'pillow your head' for those intending to use water heaters safely!
2.1. Explore Safety Technologies in Water Heaters
The most modern and safest technologies, as introduced above. A water heater considered the safest must be designed with a combination of all these features, including: ELCB electrical leakage sensor, overheat and burn prevention sensor, dry burning prevention sensor, flow control switch, water flow adjustment, user warning button, and electromagnetic compatibility (EMC) feature.
2.2. Only Choose a Heater with Shock-Proof Feature
Electrical issues are crucial as these devices are used in bathrooms, constantly in contact with water. Therefore, it is necessary to choose the safest water heaters with shock-proof features to prevent unfortunate incidents.
2.3. Always Install a Proper Ground Wire for the Heater
The ground wire is crucial alongside the internal safety systems of a water heater. Adding this component enhances the safety of the product. With prolonged use, the ground wire may accumulate residue, deteriorating its insulation properties. However, having a ground wire ensures that if there is an electrical leakage, it will be transmitted to the ground instead of affecting the user, preventing electric shocks.
2.4. Choose Well-Known Brands
When making a purchase, consider reputable, trustworthy, and quality brands. Some names you can trust for selection and purchase include water heaters from Ariston, Panasonic, Centon, Electrolux, Ferroli, or Atlantic.
Ariston water heaters boast a modern and attractive design.2.5. Check the Heater's Electrical Leakage Switch before Use
The product is designed with safety in mind, but user diligence enhances safety further. Before using a water heater, check the electrical leakage switch or warning button to ensure there are no potential issues. If the system shows signs of electrical leakage and users are not careful, unaware, or knowingly use it, the consequences can be severe.
2.6. Check the Water Temperature before Using for Children
Despite having safety temperature sensors, users must still pay attention to the water temperature before allowing children to bathe. Excessively hot water may affect the delicate skin of children, while adults may not be as affected.
Hopefully, the article above has provided the essential information to answer your questions on how to choose a safe water heater. Alongside the 6 buying criteria and analysis of 6 modern technologies present in a water heater you should consider purchasing. Wishing you find the most suitable product for your family.
