In solar configuration, an ITS indirect tank provides solar thermal energy when combined with a boiler. The ITS is fitted with 2 coils. In solar configuration the upper coil is connected to the primary circuit (boiler) whilst the lower coil is connected to the solar circuit. The top coil after- heats the water if the solar contribution is insufficient. The lower coil transfers the solar contribution which is collected by the solar collectors.
