YOUR SYSTEM TYPE EXPLAINED...
LOW PRESSURE SYSTEMS
Gravity Fed System - This can usually be identified by the presence of a hot water cylinder located in an airing cupboard or closet. Cold water is also stored in a tank above the cylinder, often in a loft or attic.
Unbalanced System - Cold water is supplied by mains pressure, whilst the hot supply comes from a cylinder fed by a header tank. Sometimes a back boiler or wall mounted boiler is used to heat a gravity fed supply but this does not have a significant effect on the water pressure. Pressure can be balanced using an equalising valve bringing both supplies to the lower pressure level. As a rough guide, there is 0.1 bar of pressure for every vertical meter between the shower head and the bottom of the tank, subject to pipe configuration and diameters.
HIGH PRESSURE SYSTEMS
Combination Boilers or Instantaneous System - Mains water is heated by the boiler with the cold supply also coming from the mains.
Unvented Hot Water System - Hot water is stored in a pressurised tank which can be located anywhere in the house. With this system there is no need for a header tank, although a small expansion tank can sometimes be seen immediately above the stored hot water. Cold is supplied at mains pressure. As mains pressure can vary considerably depending on your location, contact your local water authority who can provide further information.
NOTE: Single Function Handsets are suitable for all pressures. Some spray settings on multi mode handsets may require higher pressure depending on application.
