Storage tanks 7000 Puffer can be easily integrated into solar systems and are designed for heating supplement (not for DHW production or storage). The care taken to study the geometry of the tank (also provided with inner diaphragm) and coil (only for /S models) provides the best performance in terms of stratification, heat exchange and recovery time.
The connection at various heights permits the use of different heat generators and avoids affecting stratification.
The CFC-free polyurethane insulation reduces heat losses and, as a consequence, enhances efficiency; the hard insulation makes the installation easier (/F models).
The use of the flange (only for /F models) makes maintenance easier and allows to connect an additional exchanger.
It is possible to use additional electrical resistances.
