Vacuum Tube Solar Systems

Unlike classic flat panels, Caldomax Vacuum Tube Systems work on the "thermos" principle. The vacuum between the double-walled borosilicate glass tubes prevents the freezing cold in the environment from cooling the heated water. This revolutionary technology traps sunlight even when the outside temperature is minus degrees in winter and offers uninterrupted hot water comfort.

Thanks to Heat Pipe technology, water do not circulate inside the tubes; only heat is transferred. In this way, the risk of calcification, rusting or freezing in the tubes is completely eliminated. These systems, designed with Caldomax quality, reduce your energy costs by up to 80% even in short sunshine periods and repay your investment in a short time.
