What are the different types of showers?

What is a mixer shower?

Blends hot and cold water for the ideal temperature, are great if you have lots of stored water from a combi boiler or large hot water cylinder, and usually provide a faster flow than electric showers.

Mixer showers have 3 different temp controls:

  • With manual control, the shower temp may vary depending on changes to the incoming water supply.
  • Pressure balancing mixers compensate for a pressure imbalance between hot and cold water, for a stable showering temp.
  • Great for young families or the elderly, thermostatic mixers adjust the water temp preventing changes if another tap’s turned on.

What is a power shower?

  • Power showers mix hot and cold water to the optimum temperature.
  • They have an inbuilt pump so are able to significantly increase the water flow rate from a gravity fed system. This is a great option if you have low water pressure.

What is a digital shower?

Digital showers let you pre-programme the water temperature and flow to suit your preferences. Some showers are controlled with a wireless remote.

  • There are 2 types of digital showers, a low-pressure variant which has an inbuilt pump as part of the valve, and a high-pressure variant.
  • No pipes are on show as water is delivered through a riser rail, ceiling or wall.

What is an electrical shower?

Electric showers use an element to heat the cold water as it passes through the unit, so not to use up any stored hot water.

  • There's no pump involved, so the amount of water will depend on your mains water pressure. The higher the kilowatt rating, the more powerful the water flow.
  • They're also independent of the hot water system, so if your boiler fails you can still have a hot shower. It only requires a mains cold water supply and heats water on demand, so it’s pretty economical.

Which water system do I have?

The type of water system you have in your home will affect the type of shower you can install.

Low pressure gravity system

A cold water tank with a hot water cylinder below it (usually found in an airing cupboard). Water in the cylinder is heated by a boiler or immersion heater and fed to the taps via a pipe.

Mixer, power, electric and digital showers all work well with this system.

Mains pressure combination

A combination, or combi, boiler heats water directly from the cold mains supply. If you have a combi boiler you won't have a tank in the loft or a cylinder.

Mixer, electric and digital showers work with this system.

Mains pressure unvented

A hot water cylinder which is directly fed from the mains supply, without the need of a cold water tank. The water is heated by a boiler or immersion heater.

Mixer and digital showers work with this system.

Cold mains supply

An electric shower fitted to the cold mains supply. The water is heated automatically when switched on so you won't use up any hot water stored in a cylinder.

Only electric showers work with this system.
