Buffer vessel eldom 1500 l., With one black and one stainless steel coil, unenamelled

This buffer tank model allows you to store thermal energy simultaneously from two different heat sources, for example a solar system and a boiler. The instantaneous (flow-through) heating principle and the large capacity of the appliance provide a significant amount of domestic hot water. The corrugated heat exchanger has a large contact surface and is made of so-called medical-grade AISI316L chromium-nickel steel. This guarantees that the drinking quality of the hot water is preserved throughout the service life of the appliance. - Minimal heat losses; - Low-positioned large-area heat exchanger working in storage mode; - Easy-to-remove insulation made of expanded polystyrene with graphite nanoparticles, 100 mm thick; - Zipped cover made of synthetic wear-resistant material in INOX colour; - Connections convenient for installation and servicing; - Circulation socket; - Thermostat sockets; - Venting socket.
