5.1 - Examples of installation
WARNING! This storage tank must be used with a COSMOGAS hot water heater for the production of
DHW. Before proceeding with installation, the hot water heater’s installation, use and maintenance manual must
be read carefully.
Some examples of hydraulic connection diagrams are shown below:

hot water heater’s support bracket. In this case the positions of the solar control unit, solar assembly
and hot water heater will be on the storage tank itself.
