Using a storage electric water heater rationally can lead to significant savings on your annual electricity bills.  Here are some proven energy-saving tips: 

First of all, to save energy consumption, we suggest that you choose a water heater model with a higher energy consumption grade.

Optimal Temperature Settings

The most economical temperature range is 55-60°C.  For every 1°C increase beyond this, energy consumption rises by about 5%.  In summer, you can set it to around 45°C, and in winter, not exceeding 65°C. 

Leverage Peak-Valley Electricity Pricing

If your area implements peak-valley electricity pricing, schedule heating during the off-peak nighttime hours for daytime use.  The heat loss from an 80-liter water heater kept on standby for 24 hours is generally lower than the energy required to reheat it. 

Choose the Right Mode According to Needs

For households that use it daily, keeping it on is more energy-efficient than turning it on and off frequently.  If used only on weekends, it's best to turn it off during weekdays. 

Regular Maintenance Is Key

Descaling the tank every two years is essential.  A 1mm increase in scale thickness can raise energy consumption by 10%.  Also, check the sacrificial anode rod regularly, as excessive wear can reduce heating efficiency.

Additional Energy-Saving Measures

 Using showers instead of baths can save up to two-thirds of hot water.  During non-use periods, closing the inlet valve can minimize heat loss. 

 Installing a check valve to prevent hot water from flowing back into the cold water pipes may seem like a small detail, but its cumulative energy-saving effect over time is quite remarkable. With scientific temperature control and good usage habits, an electric water heater doesn’t have to be an "electricity-guzzling monster" in your home.
