Forced circulation kit
When the difference in temperature between the sensor located in the solar collectors and the
sensor located in the storage tank is greater than the
‘Differential Temperature’, adjusted on the
differential thermostat, the circulator of the closed circuit starts up. This is located in the hydraulic
kit. The circulator functions only for the period of time that the above situation exists and only then
the water in the boiler is being heated from the solar system (BL1 or BL2).
Especially for the system BL2 (with a helping / secondary source of energy - central heating
boiler) in the case where the above mentioned circumstances do not exist, the storage tank can
heat up from secondary source of energy (for example: central heating boiler). This occurs
through the second tube heat exchanger of the boiler. In this case we must use an additional
electric connection / start up order of the burner and the circulator of the central heating boiler.
For both systems - models (BL1 and BL2) an electric resistance as a secondary source of energy
can be used. (upon a special order).
The circulator for recirculation (optional) is used for the re-circulation of the hot water between the
storage tank (boiler) and the usually far off distributors of the hot water.
