The systems are delivered with 1 tube heat exchanger on the boiler (BL1) for connection to solar
collectors or with 2 tube heat exchangers on the boiler (BL2) for connection to solar col-lectors
and central heating system. Every system can be delivered with an electric resistance 2kW or 4kW
(upon request).
General
The forced circulation systems are used for the production of hot water.
Their basic characteristics are:
• High efficiency
• Easy installation
• Economic Function
