Block of flats, Velká skála
The solar system consists of 36 Regulus KPS11-ALP flat plate collectors. They are connected in 8 parallel arrays of which 6 arrays consist of 5 collectors each and 2 arrays consist of 5 collectors each. Solar energy gained is transferred to solar technologies through antifreeze solar liquid in copper piping wrapped in AEROFLEX thermal insulation.
The existing domestic hot water system has been retrofitted with a solar system. Before, incoming cold water was heated from district heating system through an in-house heat exchanger. Now, cold water enters the solar cylinders first and gets preheated before entering the existing DHW system. Depending on the temperature in the solar tanks, i.e. on the heat gained from the solar collectors, domestic water is preheated and lead to the heat exchanger. There it is either heated in the heat exchanger or if warm enough, it just passes through the heat exchanger and is ready to be used.
Total cost was CZK 1 750 000 incl. VAT, of which CZK 1 250 000 were covered by Green Savings subsidies.
