Blueclean 30 Tube Close Loop Solar Water Heater Stainless Steel Frame Evacuated Vacuum Tubes

描述

Blueclean close loop solar water heater has a non-pressure water tank with a high efficiency copper coil inside the tank. The liquid circulated through the collector and tank is separated from the water through the cooper coil, which prevents scale formation in the collector, or corrosion of the copper in the areas with poor water.
