Roca a fresh water solar water heater Product Overview: 

 The solar collector using all-glass vacuum tube collectors, water tank, open tank SUS304 stainless steel liner, insulation for polyurethane foam insulation, water tank built-in the SUS304 heat exchanger coil, sunny days, solar radiation energy through the natural cycle collector heat gradually collected in the tank, rainy days the water temperature is not enough, you can tank built-in electric heating system is heated to the set temperature. 

 RHES-reverse heat transfer technology and configuration of stainless steel coil heat exchanger inside the tank, the hot water tank as an energy storage medium, cold water through the stainless steel coil heat exchanger to absorb heat quickly heated, 20 seconds fast heat exchanger, the water temperature close to the tank water temperature (2 ° C temperature difference), the water pressure from the municipal pressure, dynamic pressure drop of about 5 m. 

 Appropriate to the crowd 

 Apply to hot water requirements of the higher places or family. 

 Use an ordinary drowning solar, in particular, is trapped by the water pressure problem, the second purchase of solar energy customers.
