INITIAL START-UP

Heat is only transferred from the solar heating circuit to 
the combination storage cylinder when the temperature 
of the solar collectors exceeds that in the combination 
storage cylinder. It is therefore temperature differential 
rather than absolute temperature that is important in con-
trolling solar water heating systems.

- Set the required temperature differential between the 

collector and combination storage cylinder (see the 
instruction manual for the controller).

- Start up the boiler to provide auxiliary heating for the 

combination storage cylinder.

Once the system has been started up, perform the fol-
lowing checks:

Solar heating circuit

- Check that the flow rate in the solar heating circuit is 

equivalent to 30 l/h for each m

2

 of collector area

- Check that the solar heating circuit has been properly 

bled

- Check that the cold pressure of the system is approxi-

mately 3 bar

-  Check that the safety valve operates at 6 bar

-  Check that all pipes in the water circuit have been insu-

lated in conformity to relevant standards.
