UBS 300 SF - 250 S - 200 S
Enamelled steel storage tanks with double coil and capacity of 300, 250 and 200 litres. 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.
The UBS 300 SF model is provided with thermometer and temperature probe, temperature thermostat, inspection flange positioned in the lower side and magnesium anode. It is pre-arranged for recirculation and for a supplementary heating element.
UBS 250 S and UBS 200 S models are provided with thermometer and temperature probe, inspection flange positioned in the upper side and magnesium anode. These models are pre-arranged for recirculation.
The maximum allowed pressure for domestic water circuit is 6 bar.
