Product Characteristics Extra large heat capacity and more water to satisfy the needs concerning bath and other hot water requirements. The support is designed with an overall industrial model, which is simple, direct and stable. The 2.1m extra long high temperature pipe with special effect has the patent of interferential film technology, thus increasing the heat collection performance by 12% compared to normal pipes and bearing more stable performance. The equipment has extra thick and extra strong heat preservation layer and the fully automatic constant-temperature and high-pressure quantitative foam. The heat preservation performance is endurable and steady. Solar E control equipment is adopted together with VFD display and control facilities to realize the automation and intelligence of hot water supply. Packing by carton: water tank and frame in one carton; vacuum tube is lacked in one carton
