Hot Shower Habits That Will Not Increase Your Electricity Bills

The instant shower heater is one of the biggest contributors to monthly electricity bills in many households. 

While hot showers offer convenience, especially during cold days, certain habits can cause your shower to consume far more power than necessary. However, there are a few simple adjustments that can help you enjoy hot water while keeping your electricity costs under control.

1. Avoid using the ‘High’ temperature setting all the time 

Most electric showers come with three heat settings: low, medium, and high. The high setting usually activates two heating elements instead of one. This can nearly double the amount of electricity the shower consumes every minute it is running.

While the high setting may be necessary during particularly cold weather, using it daily can significantly increase your electricity bill. In many cases, the medium setting provides sufficiently warm water for a comfortable shower. 

If the water feels slightly cool, it may be more economical to shower during warmer parts of the day rather than constantly running the unit at maximum power.

2. Prevent limescale buildup on the heating element

If you live in an area with hard water, minerals such as calcium and magnesium gradually accumulate on the shower's heating element.

Over time, this creates a layer of limescale that acts as insulation between the heating element and the water.

As a result, the element must work harder and remain on longer to heat the same amount of water. This reduces efficiency and increases electricity consumption.

In severe cases, excessive limescale buildup can shorten the lifespan of the heating element, leading to costly repairs or replacement.

To clean, ensure that the power is off and the water is turned off. Then, soak the faceplate or nozzles in a mixture of white vinegar and warm water, or use a citric acid solution. If you are unable to do it yourself, you can seek the services of a professional.

3. Switch off the shower after every use

In most homes, the hot shower heater switch has a red indicator light installed outside the bathroom. While the amount of electricity consumed by the indicator light is relatively small, it continues drawing power for as long as the switch remains on.

Some households leave the shower switched on all day or even for weeks at a time, believing that electricity is only consumed when water is running. Although the standby consumption may appear insignificant, it accumulates over months and years.

Developing the habit of switching off the shower immediately after use eliminates this unnecessary energy consumption.

4. Do not restrict water flow excessively

A common mistake among users is reducing the water flow to a tiny trickle in an attempt to get extremely hot water. While this does increase water temperature, it can actually reduce the efficiency of the shower system.

When water flow becomes too restricted, the heating element is forced to heat a much smaller amount of water. This can cause overheating, place unnecessary strain on the unit, and in some cases damage internal components.

An overheated system may become less efficient over time and require more maintenance. A moderate flow rate allows the heating element to operate within its intended range while still providing adequately heated water.

5. Keep your showers short

The simplest way to reduce the electricity used by an electric shower is to reduce the amount of time it runs.

Instant showers consume electricity continuously while heating water. This means every additional minute spent under the shower directly increases electricity consumption.
