Special water supply system
The SELTRON type ZO and ZSO storage tanks have a special water desalination system. Importantly, this system prevents the mixing of hot and chilled water returned to the storage tank. The incoming water is distributed to the appropriate temperature zone of the storage tank, depending on the heating. The unnecessary cooling, and hence the heat loss, is considerably less with this mode of operation than with conventional storage tank filling.
Hot sanitary water free of harmful micro-organisms
In the ZSO heat storage tank, the sanitary water is heated by a flow system in a stainless steel, silver-plated heat exchanger. The instantaneous heating system is one of the most efficient and safest systems for heating domestic water, as it prevents the development of the harmful Legionella bacteria.
Enough hot water in all seasons
The storage tanks allow the connection of different heating sources. During the heating season, the storage tank is charged from the heating system, and during the transition and summer periods, the energy from the solar system is added. If none of these sources are available, the domestic water can be heated with an additional heating element.
Efficient operation and long lifetime
It is very important for the economical operation of the heat store that the installed heat exchangers are free of limescale deposits. ZSO heat storages contain silver-lined heat exchangers, within which the water swirls and prevents the harmful deposition of limescale on the heat storages' walls.
Optimal use of space
Multiple heat generators and multiple consumers can be connected to the ZO AND ZSO storage tanks. The storage tanks have ready-to-connect connections at 90°, which makes installation easier, the storage tank does not require too much space and it can also be placed in a corner.
Insulation without harmful substances
It is very important that the storage tank is adequately insulated to conserve the heat energy recovered. All storage tanks shall be equipped with modern insulation that does not contain harmful substances. All storage tanks are additionally sandblasted and painted with a protective paint in the final production stage, which also protects the exterior of the tank against possible corrosion.
