1 Description
The VANTAGE range of unvented hot water storage
cylinders are indirectly heated cylinders which are desi-
gned for use with Vaillant gas boilers only. The VANTA-
GE must NOTbe installed with boilers supplied by any
other manufacturer.
VANTAGE cylinders are available in three sizes of 120,
150 and 200 litre nominal capacity. The cylinders are of
glass lined steel construction, insulated with CFC free
foam and enclosed in a decorative sheet metal casing.
They are supplied with all necessary cold and hot water
controls and are fitted with a mid position 3 port diver-
ter valve for control of central heating and domestic hot
water.
The VANTAGE cylinders are prefitted with an operating
thermostat for controlling the water temperature.
VANTAGE cylinders are also provided with an auxiliary
back up electric immersion heater, including operating
thermostat and energy cut out.
The VANTAGE cylinders operate using a mains water
pressure supply and do not require a feed from a cold
water storage tank. The VANTAGE cylinders have 22 mm
D. H. W. outlet and cold water mains inlet connections
for optimum flow rate. To achieve optimum performance
from the VANTAGE an adequate cold water mains supply
pressure and flow rate must be available (see section
7.2: Mains Water pressure).

– Single bathroom property with an en-suite shower
room:
VANTAGE 120 / 150
– Two bathroom property:
VANTAGE 150
– Two bathroom property with an en-suite shower room:

Commercial use: size depending upon hot water
requirements
Note:
1 Select the appropriate Vaillant boiler to match
the heating load (with the normal allowance for
heating up from cold) plus an allowance for
heating the hot water cylinder. Typically it is
practice to allow an additional 2-3 kW for the
hot water production.
2 Consideration should be given to the use of a
larger size of cylinder than shown above
where high water demands are likely.
