Do Showers Use Electricity? 5 Wonderful Benefits

Have you ever wondered how much electricity your shower uses? The answer not only holds the key to understanding your energy consumption, but it also paves the way for a more sustainable lifestyle.

In this article, we’ll journey through the different types of showers, their energy usage, cost comparisons, and the future of bath technologies, including smart, efficient, and electric showers.

Do showers use electricity?

Showers do use electricity, particularly electric showers.

Electric showers heat the water instantly as it passes through the unit, which can involve a substantial amount of energy because heating water is generally an energy-intensive process.

Thus, it’s essential to use it efficiently to prevent excessive electricity consumption.

On the other hand, showers like gravity-fed or mixer showers might not directly use electricity to heat water, but they could be associated with a water supply that is heated electrically.

Therefore, in a broader sense, showers often use electricity indirectly.

Five wonderful benefits of using an electric shower

1. Instant hot water

One of the most appealing benefits of using an electric shower is that it provides instant hot water. Unlike other traditional water heating systems that require waiting for the water to heat up, electric showers work by rapidly heating the water as it flows through the unit.

This means that there is no need to worry about waiting for a hot water tank to fill up or heat up. You can enjoy a hot shower any time you wish, which is especially beneficial during the winter months or on chilly mornings.

2. Energy efficiency

Electric showers are known for their energy efficiency, mainly because they heat the water only when required. They eliminate the need for a hot water storage tank where heat can be lost over time, thus preventing energy waste.

This on-demand hot water system ensures that only the necessary amount of water and electricity is consumed. As a result, electric showers can contribute to reducing your overall carbon footprint and help lower your energy bills.

3. Independence from the central heating system

Another significant advantage of electric showers is that they are independent of the central heating system. This means that even if your boiler or gas supply has issues or is turned off, you can still enjoy hot showers.

This independence makes electric showers an excellent backup option for homes that rely on other heating systems, ensuring that you always have access to hot water.

4. Space-saving and easy installation

Electric showers occupy minimal space in the bathroom since they don’t require a separate hot water storage tank.

The compact size ensures they fit easily into smaller bathrooms or shower rooms without affecting the overall design. Furthermore, electric showers are relatively easy to install and can be installed by a professional electrician with minimal disruption to your home.

This easy installation not only makes them a popular choice for homeowners but also an ideal solution for rental properties when a quick installation is required.

5. Customizable temperature control

Electric showers come with a wide range of temperature settings, allowing you to customize the water temperature according to your preferences.

This feature is advantageous for those who are particular about their shower temperature or have sensitive skin that cannot tolerate extreme temperatures.

Also, some models offer a feature called “phased shutdown” that cools the remaining water in the system, helping to prevent lime scale buildup and ensuring that the next user doesn’t experience a sudden burst of hot water.

How do electric showers work?

Electric showers work by taking in cold water from the mains supply and running it through the shower unit, where it passes over a built-in heating element. This element rapidly heats the water, providing hot water essentially on demand.

An important part of the process is the shower’s control system, which oversees the rate of cold water flow into the unit and its subsequent heating.

A slower water flow results in hotter water because the water spends more time in contact with the heating element. On the other hand, if the flow rate is high, the water may not heat up as much and therefore be cooler.

Moreover, most electric showers have a thermostat to maintain a uniform temperature, adjusting their heating as necessary. This feature allows the shower to maintain a consistent water temperature despite any fluctuations in the temperature of the incoming cold water.

Uniquely, electric showers operate independently from the home’s main boiler or hot water system. This makes them an excellent choice for homes with a problematic or nonexistent hot water supply.

They use electricity to heat only the water that’s in use at a particular time, making them an energy-efficient choice for showers.

Types of showers: Electric vs non-electric

When it comes to showers, there are various types to consider, each of which falls into one of two categories: electric or non-electric. Let’s look into the differences between electric and non-electric showers, with the latter comprising several subcategories.

1. Electric showers

Electric showers are standalone units that use electricity to heat water as it flows through the device. They connect directly to the cold mains water supply, eliminating any reliance on a separate water heating system. Key benefits of electric showers include:

  • Instant hot water, as water is heated on demand.
  • Energy efficiency, since they heat only the water being used.
  • Independence from the home’s central heating system
  • Simple installation, requiring only a connection to the cold water supply and an appropriate power source.

2. Non-electric showers

Non-electric showers, on the other hand, do not rely on an electric heating element to heat water. Instead, they utilize hot water from a home’s central heating system, boiler, or immersion heater. Several types of non-electric showers exist:

  • Mixer showers: These showers combine hot and cold water in a mixing chamber to achieve the desired temperature. Options in this category include manual mixer showers and thermostatic mixer showers. They may be wall-mounted, concealed, or, in some cases, even part of a bathtub.
  • Power showers: Power showers have much in common with mixer showers, blending hot and cold water from a home’s existing supply; however, they also contain an electric pump that increases water pressure. Consequently, they deliver a more powerful water flow, creating a more stimulating shower experience.
  • Digital showers: Digital showers are a modern type of mixer shower that precisely controls the water temperature through the use of digital technology. This advanced category includes wireless remote controls, touchscreens, and sophisticated features like custom temperature settings.
  • Eco showers: Eco showers are designed to use less water than traditional showers, helping to conserve resources and lower utility bills. These solutions typically serve as a subcategory of mixer showers, but with features that specifically focus on minimizing water waste while still providing a satisfactory shower experience.

Each of these shower options has its own unique benefits and drawbacks, so it’s essential to analyze factors like your home’s current water system, space constraints, budget, and personal preferences when making a decision.

Difference between electric showers and power showers

  • Water heating method: Electric showers are independent of the household’s hot water supply. They operate by taking water from the cold mains supply and heating it instantly as it passes through the unit. This independence makes them particularly popular in family homes where hot water can be used up quickly. In contrast, power showers mix water from both the hot and cold supplies.
  • Water pressure: Power showers use an electric pump to increase water pressure and create a more vigorous water flow. This makes them a preferred option for those who enjoy a more powerful shower experience. Electric showers, on the other hand, do not include a pump and rely on the existing water pressure.
  • Energy efficiency: Electric showers are generally considered more energy-efficient. Since they heat water only when necessary, they typically use less water than power showers. Therefore, electric showers tend to be more economical in terms of electricity costs and water consumption.
  • Temperature control: Power showers have built-in temperature control systems that allow users to conveniently regulate the water temperature, providing safe and comfortable shower conditions.
