Manual - Solar hot water systems 0020009607_02

5.1.3 Intended 

use

The Vaillant solar cylinders auroSTOR VIH S GB 200 S, 
VIH S GB 250 S and VIH S GB 250 are unvented, 
indirectly heated hot water cylinders for solar systems 
designed for usage with boilers in hot water supply 
systems in accordance with the GB standard.
They are used only to supply potable water heated up to 
85 °C in solar systems with a collector array. They may 
only be used for this purpose. The solar cylinders can be 
used in combination with a downstream boiler for hot 
water supply in accordance with the GB standard.

Caution!
Risk of damage!
The appliances may only be used to heat up 
potable water. Damage to the appliance due to 
corrosion cannot be excluded if the water does 
not correspond to the specifications of the 
water ordinance.

Any other use or extended use is considered to be 
improper. The manufacturer/supplier is not liable for any 
resulting damage.The owner alone bears the risk.
Intended use includes the observance of the system 
manual and the adherence to the inspection and 
maintenance conditions.

Caution!
Any improper use is forbidden.

Valliant solar cylinders are state-of-the-art appliances 
which have been constructed in accordance with 
recognised safety regulations. Nevertheless, there is still 
a risk of injury or death to the user or others or of 
damage to the equipment and other property in the 
event of improper use or use for which they are not 
intended.

5.1.4 Data 

badge

The data badge has been applied to the top of the solar 
cylinder by the manufacturer.

5.1.5 Safety 

devices

The solar cylinder has been provided with all safety and 
control devices for operation of the unvented domestic 
hot water supply:
–  Temperature and pressure relief valve (95 °C, 7 bar)
–  Pressure limiting valve (3.5 bar) with line strainer
–  Expansion relief valve (one port valve, 6.0 bar)
–  Thermal cut out of the solar pump, set to 90 °C, 

connected to the solar pump in order to isolate this 
heat source in the event of failure of the solar control.

–  Thermal cut out of the immersion heater
–  Thermal cut out of the solar cylinder, set to 90 °C,

connected to the motorised 2 port valve, in order to
isolate the primary heat source in the event of failure
of the domestic water thermostat.

5.1.6 

Safety instructions and regulations

This product has been checked for adherence to the 
building regulations for unvented hot water cylinder 
systems. It may not be changed or modified in any way 
whatsoever.
It should be installed by a qualified specialist, who 
should observe the applicable regulations of the local 
authorities, the building regulations, the building 
regulations for Scotland, the building regulations for 
Northern Ireland and the directives of the local water 
supply companies.Building approval is required for the 
installation.The local authority should be notified about 
the intended installation.Only original spare parts from 
Vaillant Ltd. may be used for the replacement of parts.

5.1.7   Scope of delivery

•  Check the scope of delivery of the cylinder box.
-  Water control pack (pressure limiting valve, expansion 

relief valve; connections for: secondary return, hot 
water expansion vessel)

-  Motorised 2 port valve
- Tundish
-  Cylinder drain valve
- System description
- Assembly set for hot water expansion vessel
- Hot water expansion vessel:

-  18 litres for VIH S GB 200 S

(max. storage volume at 3.5 bar = 255 l)

-  25 litres for VIH S GB 250 /300 S

(max. storage volume at 3.5 bar = 315 l)

-  Thermal cut out for solar pump with holder
- Solar cylinder

Make sure the cylinder is stored in an upright position in 
a dry environment prior to its installation.

5.1.8 

Requirements of the installation site

Place the solar cylinder at an appropriate place in the 
building, while observing the following:
–  The discharge pipe from the tundish must be installed 

at a minimum slope of 1:200 and end at a safe and 
visible point (refer to Section 5.7, Installation of the 
discharge pipe).

–  The installation surface must be level and able to bear 

the weight of the full cylinder (refer to Section 5.1.2, 
Technical data of the auroSTOR solar cylinder).

–  The installation site may not be prone to frost.A frost 

protection thermostat must be installed if necessary.

–  The controller of the installed cylinder thermostat 

under the front plate must be accessible to the owner.

–  There must be sufficient space to install, check and 

repressurise the expansion vessel.

–  Floor unevenness should not be greater than those 

able to be compensated by the adjustable feet of the 
solar cylinder.
