-Double DHW heat exchanger and stainless steel corrugated coil AISI 316L, which acts as a semi-instant hot water producer.
-The possibility of using the system as a multi-energy "buffer" with parallel connection of several sources (boiler+ solar system + heat pump or biomass boiler).
-The tanks are insulated externally with a soft polyurethane coating (100 mm thick).
-DHW production is carried out using an internal stainless steel heat exchanger AISI 316.
-These models are used to produce domestic hot water (semi-quick) and to store system hot water for heating.
