Double Serpentine Boiler

Double Serpentine Boilers are devices used to transfer the heat obtained in solar collectors to the domestic water with the help of the lower coil. In cases where solar energy is not sufficient, the heat obtained from the boiler or boiler is transferred to the domestic water with the help of the upper coil. Thus, the boiler works in a bivalent way. Electric heater can be optionally installed as a third energy source.
