The electric water heater is without a doubt one of the biggest consumers of electricity in the home, but there is a simple way to save energy with it.

Most water heaters come with a preset temperature, but if you want to reduce electricity use, experts recommend setting the thermostat to an economy mode, usually between 50°C and 60°C.

An electric water heater can use around 2 kWh per hour. If it runs for about two and a half hours each day, it may consume roughly 150 kWh per month.

Unlike some other household appliances, a water heater will not always save more energy simply by being turned off frequently. That is because the water must be heated again from the beginning every time it is switched back on. For this reason, it is usually better to turn it off only when you will not need hot water for a longer period of time.

Choose the Right Temperature

Many people make the mistake of overheating water. Setting the temperature too high, such as 75°C to 85°C, can lead to much higher electricity consumption. It can also encourage the buildup of mineral deposits inside the appliance.

Keeping the thermostat at a more moderate temperature can help reduce energy use and support the more efficient operation of the water heater.

Why Regular Cleaning Matters

To keep the water heater working properly, regular maintenance is very important. The heating element and the inside of the unit should be cleaned at least once a year.

When mineral buildup forms inside the heater, it can reduce efficiency and force the appliance to use more electricity to heat the same amount of water.

One common sign that your water heater may need cleaning is if you hear hissing or buzzing sounds while it is running. These noises often suggest that scale has built up on the heating element and should be removed.

A Simple Step That Can Save Energy

Cleaning your water heater regularly, using a moderate temperature setting, and avoiding unnecessary overheating can all help lower electricity use in your home.

Sometimes, a small maintenance habit can make a big difference in both performance and monthly energy costs.
