Stored water capacities

UK
The minimum capacity of the cold storage cistern should not be less than
225 litres (50 gallons). The capacity of the hot cylinder must be capable of
meeting the anticipated demand.
BALANCED HIGH-PRESSURE SYSTEM
The Midas range is designed to operate with unvented hot water storage
systems up to a maximum pressure of 10 bar. The cold water supply must
be drawn from the same mains supply as that to the hot water system
(down stream of the cylinder manufacturers pressure limiting valve, where
supplied) and the hot supply from the nearest convenient draw off point.
Account must be taken of pressure drops that may occur when other
draw-off points are used while the shower is in use. A typical layout is
shown on page 9.
COMBINATION BOILER SYSTEM
The Midas range is suitable for use with combination boiler systems.
The combination boiler MUST have a minimum rating of 24kW (80,000
Btu) and be of the type fitted with a fully modulating gas valve. This is
sufficient to operate one outlet point at a time.
For pressure refer to page 5.
The cold supply can be taken from the nearest convenient mains supply
and the hot supply can be taken from the nearest hot water draw-off point.
Account must be taken of the pressure drops that will occur when
other draw-off points are used while the shower is in use. A typical layout
is shown on page 9.
When fitted to combination boiler systems, Midas shower valves have been
designed to give optimum temperature control and stability from fully
modulating combination boilers and instantaneous gas water heaters.
If temperature adjustment is required, refer to cartridge adjustment
instructions on page 32.
