Planning the position of the SV30AWX
This low-tech plant is designed to let the forces of nature work for you to the maximum practical extent. This
will benefit the environment and reduce your costs of living for many years ahead.
In order to ensure the optimal performance of your S 30AWX it is important to consider:-
• The position of the solar collector in relation to the sun and to the rooms of the house
• The position of the other components in relation to the collector and the construction of the house
• The interaction between the various parts of the system
The instructions given below will take you through this process step by step
2.1 How to position the SV30AWX solar collector
• In relation to the s n:
When planning the position of the collector on roof or wall you will have to consider how the maximum
amount of sunlight can be received. If possible the collector should be directed at solar noon. However,
a deviation of up to 45º is acceptable. The inclination from horizontal should range between 30º and
60º. App. 45º is optimal.
• In relation to the rooms of the ho se:
Please note that the incoming fresh, warm air can only be achieved with the inlet vent in the immediate
vicinity of the collector, so it is important to place the collector above (or against) a room well suited for
this purpose.
Please read separate instr ctions for f rther details.
2.2 How to position the hot water cylinder
The hot water cylinder should be installed so that the horizontal distance to the S 30AWX solar collector is
as short as possible.
The hot water cylinder can often be located in a scullery or a furnace room or wherever practical. However,
there must be access to both power and the domestic water s pply.
The location should incl de a drain as water will occasionally drip from a safety valve.
An open space of 50 cm minimum should be maintained in front of the cylinder for service access.
If possible, ensure that additional space is reserved for service of the equipment below the bottom of the cyl-
inder too. In case of restricted space, a safety valve may be placed on the side of the cylinder.
Space must be reserved for piping to and from the S 30AWX solar collector. Lead-in is often made through
ceiling and floor. Please note that all piping to and from the collector must be insulated.
If the hot water cylinder is located in a loft, a frost-proof outlet must be established. Use anti-freeze to avoid
potential frost in the pipes. If an electric water heater is used for frost protection a thermostat should be in-
stalled to prevent it from working when the room temperature exceeds +5ºC.
Take care not to impair or damage the fabric of the b ilding when installing the hot water cylinder.
