3 Counties Heating specialise in installing showers, including power showers, as well as shower enclosures and shower screens.

Choosing a Shower
The type of shower you choose can depend on your existing water supply system, which will be either:
- a low pressure or gravity-fed system (most common);
- a high pressure or unvented system often found in newer systems.
A low pressure system uses either a combination boiler that heats water instantly or a standard boiler with a cold water tank in the loft and a copper cylinder to store hot water. A high pressure system takes water straight from the mains and hot water is stored in a high pressure water cylinder.
Types of Shower
There are three basic types of shower: electric, mixer and power.
Electric showers are independent of the existing hot water system so are suitable for any home, regardless of the type of water supply system. They are generally the most economical type of shower and provide instant hot water as soon as you turn them on, but they tend to have a lower flow rate than other types. Electric showers can have problems in hard water areas with the build up of scale if you do not have a water softener.
Mixer showers take water from both the hot and cold water supplies and different versions are available for low and high pressure systems.
Power showers are similar to mixer showers, but are fitted with a pump that provides a much faster and more powerful flow of water.
