4.2 Installing diverter valve for return boost (optional)
The "return boost" function for boosting the heating system using the solar thermal system requires
a diverter valve to be fitted. The diverter valve directs the flow of central heating water either through
the thermal store or directly back to the boiler depending on the heating system's return tempera-
ture.
