10.5kW Electric Shower Upgrade in Plymouth – More Power, Better Showers

At Dave Prout Electrician Plymouth, we were recently called out to a customer who was frustrated with their old shower setup. The existing unit was only a 7.5kW electric shower, fed by a 6mm cable and protected by a 32amp breaker. The result? A weak, underpowered trickle of water that just didn’t deliver the showering experience they wanted.

After a detailed inspection and consultation, the customer decided to upgrade to a much more powerful 10.5kW electric shower. This required a full system upgrade to safely and efficiently handle the increased power demand.

What the Upgrade Involved

• Removal of the old 7.5kW shower and all related fittings
• New 10mm twin & earth cable installed to safely carry the higher load
• 50amp pull cord isolator switch fitted for safe operation
• 50amp protective device (MCB/RCBO) fitted in the consumer unit
• Installation of a brand new 10.5kW Mira electric shower (pictured above)
• Full testing, inspection, and certification of the new circuit

Why Upgrade to 10.5kW?

Many households start with smaller 7.5kW or 8.5kW electric showers, but these can often feel underpowered. By upgrading to 10.5kW, customers benefit from:

• Stronger water flow for a more refreshing shower
• Improved hot water performance, especially in colder months
• Modern safety features with up-to-date cabling and protection
• Reliable performance thanks to professional installation and certification

Installation Time

The full system upgrade, including cable, isolator, protective device, and shower installation, was completed in just one day. The customer now enjoys a powerful, reliable showering experience with peace of mind that their installation meets the latest standards.

Thinking About an Electric Shower Upgrade?

If your shower feels weak, trickles, or struggles to heat water, it may be underpowered or on undersized wiring. Upgrading to a modern 10.5kW shower with the correct cabling and protection can transform your bathroom.
