Heating buffer vessels with corrugated stainless steel tube coil for instantaneous DHW production
Buffer tanks suitable for civil and industrial installations for production and storage of heating system water while producing DHW instantaneously. These enable high heat exchange performance with significant hourly production of domestic hot water. Particularly suitable, due to significant heat exchange surface of the coils, to be used to integrate any additional primary source, i.e. solar panel and/or another energy source, keeping the circuits independent of one another. The stainless steel corrugated tube coil contained inside these calorifiers, dimensioned to meet high consumption peaks, is designed with the distribution of the spirals that is optimal for obtaining maximum performance by fully exploiting the heat stratification zones of the whole volume of heating water inside the tank. The instantaneous DHW production eliminates the possibility of legionella bacteria proliferation.
