A good shower isn't just a luxury; it's a necessity that enhances your quality of life.

This guide from Asturias Bathrooms aims to provide you with a complete breakdown of electric and mixer showers, helping you understand their differences, pros and cons, and which one best fits your household needs. By the end of the post, you'll have all the insights you need to make an informed decision.

What's the Difference Between Electric Showers and Mixer Showers?

When comparing electric and mixer showers, it's essential to consider their key differences in terms of functionality, installation, and water heating methods.

Electric Showers

Electric showers heat water instantly via an internal heating element, similar to how a kettle works. They are independent of your home's central heating system, meaning they draw cold water directly from your mains supply.

Key Features:

• Operates independently of your boiler or hot water system.
• Offers on-demand hot water.
• Requires an electrical connection and a suitable water pressure.

Mixer Showers

Mixer showers, on the other hand, blend hot and cold water from your home's water system, delivering a steady stream of your desired temperature. They rely on either a mains-fed or gravity-fed water system connected to a boiler or water tank.

Key Features:

• Depends on your home's existing hot water supply.
• Provides better water flow and temperature control.
• Requires a compatible water pressure system.

Understanding these differences lays the groundwork for evaluating their advantages and disadvantages further.

Pros and Cons of Electric Showers

Advantages of Electric Showers

• Energy Efficiency: Since electric showers only heat the water you use, they can be more energy-efficient than systems where hot water is pre-heated and stored.
• Hot Water on Demand: With their instant heating technology, you'll never run out of hot water, even if your boiler fails.
• Cost-Effective Installation: Electric showers are typically more straightforward and less expensive to install, especially in homes without an existing hot water system.
• Flexibility: They are an excellent choice for en-suites or secondary bathrooms where a hot water supply may be limited.

Disadvantages of Electric Showers

• Water Pressure Limitations: Electric showers rely heavily on your home's incoming mains pressure. If your mains water pressure is low, the flow rate may be underwhelming.
• Moderate Heating Capacity: During colder months, electric showers may struggle to heat water as quickly, especially in regions with very low groundwater temperatures.
• Electrical Installation Requirements: Fitting an electric shower requires professional assistance to ensure safe electrical connections, which might raise costs.

Pros and Cons of Mixer Showers

Advantages of Mixer Showers

• Superior Water Flow: Mixer showers generally offer a more substantial and more luxurious stream of water compared to electric showers.
• Temperature Control: These showers provide better temperature precision, offering a more consistent experience.
• Variety of Styles: Mixer showers come in a range of modern designs, such as thermostatic mixers, which protect against sudden temperature surges by automatically adjusting the water flow.

Disadvantages of Mixer Showers

• Dependent on Existing Hot Water System: If your boiler fails or your hot water cylinder runs out, you'll have no hot water in your shower.
• Potential Water Pressure Issues: Homes with gravity-fed systems may require an additional pump to boost water pressure, which increases installation costs.
• Higher Initial Costs: Installing a mixer shower can be more expensive, especially if your plumbing system needs modifications.

How to Choose Between Electric Showers and Mixer Showers?

When making your decision, consider the following factors:

Household Needs

• If you need a shower that works independently of your boiler, an electric shower is the way to go.
• For larger households with high water demands, a mixer shower (paired with a sufficient hot water tank) offers a better experience.

Budget

• Electric showers are generally more affordable to purchase and install, making them ideal for tighter budgets.
• Mixer showers might cost more upfront but offer enhanced functionality and style for those willing to invest a bit more.

Water System Compatibility

• Electric showers are suitable for homes with low-pressure systems as they don't rely on existing hot water tanks.
• Mixer showers are better if your home already has a reliable central heating system with sufficient water pressure.

Use this framework to align your preferences with the technical requirements of each shower type.

Tips for Installation and Maintenance

Installing Electric Showers

• Hire a qualified electrician to ensure proper electrical connections and compliance with safety regulations.
• Check your home's water pressure. Installing a pump or small booster may be required for houses with low mains pressure.

Installing Mixer Showers

• Consult a plumber to ensure your shower is compatible with your water system. Gravity-fed systems may need a pump for proper water pressure.
• Opt for a thermostatic mixer if your household experiences frequent temperature fluctuations in water supply.

Maintenance Tips for Both

• Regularly descale your shower unit to prevent limescale buildup, especially in hard water areas.
• Periodically check showerheads and hoses for leaks or clogging.
• Follow the manufacturer's maintenance instructions carefully for optimal performance.

By scheduling regular maintenance, you'll ensure the longevity of your shower and reduce the risk of unexpected breakdowns.

The Final Choice is Yours

Choosing between an electric and a mixer shower ultimately comes down to your circumstances. If you prioritise energy efficiency, on-demand hot water, and affordability, an electric shower may be the perfect fit. Alternatively, if luxury, consistent temperature, and stronger water flow are your top priorities, a mixer shower is worth the investment.

Both types have their unique benefits and drawbacks, so weigh your options carefully. If you're still unsure, feel free to reach out to a shower installation professional or retailer for advice tailored to your home.
