Look at the picture and identify what type of system it is.

• Direct cold water with combination boiler (high pressure)

• Indirect cold water from CWSC in loft area (low pressure)

• Indirect hot water from the CWSC via the cylinder (low pressure)

• Direct cold water (high pressure)

• Direct cold water (high pressure)

The water pressure is high

• Direct cold water system

• Indirect cold water system

The lower down the outlet is in the property, the higher the

pressure because of gravity pushing the water down

• Direct cold water system

• Indirect cold water system

The system is more expensive to install as there are more

pipework and components to install

• Direct cold water system

• Indirect cold water system

The water pressure is low

• Direct cold water system

• Indirect cold water system

If the mains is cut off there is a limited supply of water available

• Direct cold water system

• Indirect cold water system

This system requires that the kitchen sink is the only outlet

that must have wholesome water

• Direct cold water system

• Indirect cold water system
