CE Certified High Pressurized Solar Water Tank wit

High pressurized solar water tank with twin copper coils heat exchange for solar or combination system. Rigid, polyurethan foam insulation keeps heat in the tank. it meets or exceeds the most demanding energy efficiency standards without an extra insulation blanket. electrical heating element assists the system only when the solar energy cannot maintain the desired temperature or during period of peak demand. To ensure the high quality of these tanks, advanced rolling and welding machine are utilized. each inner tank is individually tested for high pressure up to 10 bars. Tanks range from 150L to 300L and they could come with or without coil exchanger. All tanks are CE certified.
