Electric Shower

Electric showers: a quick introduction for UK homes

Electric showers are one of the most common types of shower in the UK. Being self-contained, they don’t need a hot water supply from elsewhere. Here I give you a quick introduction to electric showers and their pros and cons.

What is an electric shower?

An electric shower unit is a box that fits to your wall, fitted with a hose and a shower head. It connects to a mains cold water supply and mains electricity, where the water is heated to a temperature you choose via a thermostatic-controlled dial.

This is quite different from a standard mixer shower, which mixes hot and cold water supplies; or the digital version, which allows you minute control over the flow and temperature. These work in homes with a combi boiler or hot water cylinder as they depend on an existing supply of hot water.

Pros of an electric shower

  • Will work in virtually any home
  • Suits a home with low pressure water supply such as gravity fed water from a tank in your loft
  • Great if multiple people are having consecutive showers – you won’t run out of hot water
  • No need to reroute hot water pipes
  • Economical as they only heat the water you use

Cons of an electric shower

  • Unit is visible and may not be the look you want
  • Heating elements can be affected by limescale in hard water areas

How to fit an electric shower

You can do an electric shower installation yourself with a minimum of tools, as long as you’re able to switch off the mains water but you must have a qualified electrician to do the electrical connections for you.
