1. Practices Contributing to Electricity Waste with Hot Water Heater Usage
Neglecting regular maintenance and constantly running the hot water heater pose risks to users and result in unnecessary energy wastage.
Showering While Simultaneously Operating the Hot Water Heater

Turn off the hot water heater before use to ensure maximum safety.
Safety Features in Modern Hot Water Heaters

Adjust the temperature level for the heater and only activate it when needed.
Running the hot water heater all day has some benefits, ensuring constant hot water availability. However, this practice is not advisable for both safety and cost reasons. The continuous heating cycle consumes a significant amount of energy, leading to corrosion and calcium deposits on the heating element. Keeping the heater on 24/7 also poses safety hazards, as mentioned earlier.

Importance of Regular Maintenance for Hot Water Heaters
Hot water heaters should undergo maintenance at least once a year, particularly before the cold season when there is higher hot water demand. Failure to do so may result in various risks such as electrical leakage, fire, or decreased heating efficiency, consuming more energy. Cleaning the heating element is cost-effective, with the current price being approximately under 500,000 VND. Regular cleaning and inspection of the Earth Leakage Circuit Breaker (ELCB) component are crucial for safety.
