What should I pay attention to when using the electric water heater
Electric water heaters have become a common household appliance, especially during autumn and winter when the demand for hot water increases. While these devices offer convenience, safety should always be the top priority. Many accidents occur due to improper usage, so it's essential to understand how to use electric water heaters correctly. In this article, we’ll walk you through the proper ways to operate both instant and storage-type electric water heaters.
How Electric Water Heaters Work
Electric water heaters work by using a thermostat to control heating cycles. When the water temperature drops below a set point—usually around 50°C—the heater turns on and heats the water until it reaches the preset temperature, typically between 75°C and 85°C. Once that temperature is reached, the thermostat switches off, stopping the heating process. This cycle ensures the water remains at a consistent temperature while minimizing energy waste.
There are two main types of electric water heaters: instant and storage. Let’s explore each one and learn how to use them properly.
Proper Use of Instant Electric Water Heaters
Instant electric water heaters, also known as tankless models, heat water on demand, making them highly efficient. They’re ideal for bathrooms and kitchens where hot water is needed regularly. Here are some key tips for their safe and effective use:
- Initial Setup: Before turning it on for the first time, make sure to flush the unit with water to prevent dry burning. This helps protect the internal components.
- Power and Water Safety: Always turn off the power and water supply after use. Regularly clean the internal filter to avoid clogging and maintain performance.
- Magnesium Rod Replacement: Most units come with a magnesium rod that acts as a sacrificial anode, protecting the inner tank from corrosion. Replace it every few years to ensure long-term durability.
- Regular Cleaning: Over time, mineral buildup can reduce efficiency. Clean the heating elements and inner tank periodically to maintain performance and extend the lifespan of the unit.
Proper Use of Storage Electric Water Heaters
Storage electric water heaters keep a reserve of hot water ready for use. They are more affordable and widely used, though less energy-efficient than instant models. Here’s how to use them effectively:
- Energy-Saving Tips: If you don’t use hot water frequently, consider turning off the heater when not in use. For daily use, heat it about an hour before you need it to save energy.
- Keep It Filled: Always fill the tank with cold water before turning on the power. Ensure the tap is open to avoid pressure issues or overheating.
- Safe Usage: When using the hot water, open the cold water valve first, then the hot one. When shutting down, close the hot water valve first to prevent scalding.
- Temperature Adjustment: Adjust the temperature setting based on your usage frequency. Lower settings can help save energy without compromising comfort.
While storage heaters may not be as efficient as instant models, they remain a popular choice due to their affordability and simplicity. However, regardless of the type, proper maintenance and correct usage are crucial for longevity and safety.
Whether you're using an instant or storage model, understanding how to operate your electric water heater safely and efficiently is essential. Always read the manufacturer's instructions and follow safety guidelines to ensure a long-lasting and trouble-free experience.
