Low pressure gravity systems

We recommend:

• Mixer Showers (with optional pump for stronger flow)
• Power Showers

If your hot water cylinder is large enough and you want a more powerful shower, it is possible to boost your system with a shower pump.

High pressure water systems - Combination Boiler

If you have a combination boiler (Combi) which heats water on demand, then you'll have a high pressure water system.  These boilers are generally the size of a kitchen cupboard stored somewhere in your house. You won't have hot and cold water tanks.

Combi boilers send hot water into the central heating system and to the hot water outlets (taps / shower, etc.)

We recommend:

• Mixer Showers
• Power Showers

High pressure water systems - Unvented

If you have a hot water cylinder in your airing cupboard but no cold water tank in your loft, then you'll have an unvented System.  

This essentially means you have a mains water fed cylinder delivering a high flow rate of hot water. There is equal pressure between hot and cold water taps through the whole house.

 A shower pump is not required for this type of water system.

We recommend:

• Mixer Showers (for a powerful flow)
• Power Showers (for a powerful flow)

Cold mains supply

You don't have stored hot water at all or, don't want to use up all the hot water when you have a shower.

We recommend:

• Electric Showers (the higher the kW the stronger the flow)
