UBS 1000-750-500-300 S
Enamelled steel storage tanks with double coil and different capacities, from 1000 to 300 litres, provided with thermometer and temperature probe, inspection flange and magnesium anode. The double coil allows the connection of the storage tank to a solar system, thus obtaining the combined production of domestic hot water by means of the boiler and the solar energy.All models are pre-arranged for recirculation and for a supplementary heating element.
The maximum allowed pressure for domestic water circuit is 10 bar.
