Solar Thermal Collector

This heat pipe solar thermal collector is a pressurized split solar component, with full copper manifold inside and aluminum outer shell. The evacuated tube with high selective coating achieves 94%-96% solar absorption rate, paired with glass wool insulation to reduce heat loss. No domestic water inside vacuum tubes avoids scaling and corrosion, it can be installed on roof, wall to match architectural style. Certified by Solar Keymark & CE EN12975, it works normally under -35°C low temperature, widely used for villa domestic hot water, floor heating system.
