INSTALLATION - SOLAR COLLECTORS
FLOW AND RETURN LINE LAYOUT
To ensure that the system is operating at optimum efficiency, it is important to ensure that the flow through all the
collector arrays is balanced. This can be achieved by using the 'first in last out' approach to ensure equal length
flow and return lines for all collector arrays as shown below.
Alternatively balancing valves may be used on each collector array. This may simplify the pipework layout and
cost.
