If you have a combi boiler, you have two excellent options when choosing a shower system: an electric shower or a thermostatic mixer shower. Each has distinct benefits, and your decision will depend on your household needs and preferences. Below, we explore both options to help you make the best choice for your home.
Electric Showers
An electric shower is an independent system that heats water on demand using electricity. This means it does not rely on your combi boiler for hot water. Here are the key benefits of choosing an electric shower with a combi boiler:
Backup Hot Water Supply: If your combi boiler were to break down, an electric shower would still provide you with hot water, as it operates independently of the boiler.
Energy Efficiency: Electric showers only heat the water you use, making them highly energy-efficient for households with low hot water demands.
Ease of Installation: Electric showers are straightforward to install and can work in homes where the mains water pressure is consistent.
However, electric showers typically have a lower flow rate compared to other systems, so they may not be the best option if you prefer high-pressure showers.
Thermostatic Mixer Showers
Thermostatic mixer showers are designed to mix hot water from your combi boiler with cold water from the mains supply, delivering a consistent and comfortable showering experience. Here’s why this option may be ideal:
Better Flow Rate: If your mains water pressure is strong and your combi boiler is adequately sized, a mixer shower can deliver an excellent flow rate.
Temperature Stability: The thermostatic mechanism ensures the water temperature remains constant, even if other taps in your home are in use.
Customisation: Many mixer showers come with adjustable flow and spray settings, providing a more luxurious experience.
The performance of a thermostatic mixer shower depends largely on the capacity of your combi boiler. Larger combi boilers with higher flow rates can provide a more powerful shower experience.
Choosing the Right Shower
When deciding which shower is best for your combi boiler, consider the following:
Backup vs Performance: If you value having a backup hot water supply in case of a boiler breakdown, an electric shower is a reliable option. If you prioritise a stronger flow rate and luxurious showering experience, a thermostatic mixer shower is the way to go.
Boiler Size: The size and capacity of your combi boiler play a significant role in the performance of a mixer shower. For households with larger boilers and higher mains pressure, a mixer shower can be particularly effective.
Water Pressure: Electric showers work well with consistent mains pressure, while mixer showers thrive with a well-sized combi boiler and good water flow.
Household Needs: Consider the number of people in your household and their showering habits. Mixer showers are ideal for families with higher water demands, while electric showers suit homes with fewer occupants.
Final Thoughts
Both electric showers and thermostatic mixer showers offer unique benefits when paired with a combi boiler. Electric showers provide a practical backup hot water source, while mixer showers offer superior flow rates and temperature control for a premium experience. Assess your home’s water pressure, combi boiler size, and household needs to make the best choice for your shower system.
