Import Compact Non-Pressure Solar Water Heater — Buy in Bulk from Supplier in China

The Compact Non-pressure Solar Water Heater from Shanghai APS Solar Energy Co. Ltd. uses a stainless steel inner tank in SUS304-2B or SS316L grades with a thickness of 0.31 to 0.51 mm, paired with an outer tank of color steel or stainless steel at 0.40 mm thickness. The system integrates polyurethane foam insulation ranging from 30 to 60 mm for thermal retention, and its frame options include galvanized steel, aluminum alloy, or stainless steel, customizable to installation angle requirements. Vacuum tubes are available in ALN/ALN-SS/Cu layer configurations with standard lengths of 47-1500 mm or 58-1800 mm.

Tank capacity spans 70 to 400 litres, with optional accessories such as an assistant tank heating element, magnesium rod, reflector, and intelligent controller for automated operation. The unit operates non-pressurized, making it suitable for flat or inclined roof installations, and can be paired with an electric booster to ensure hot water availability without direct sunlight. Typical industry specifications for such systems include a heat retention efficiency of above 70% over 24 hours and a vacuum tube absorption rate exceeding 92%, though these values should be confirmed with the supplier for this model.

This model is designed for applications like camping areas and holiday residences, where non-pressurized systems are preferred for simplicity and reliability. Buyers in regions with variable sunlight or seasonal use often select this type for its wind resistance and stable performance. Trade terms such as MOQ, packaging, and lead time are not specified in the listing and should be requested directly from Shanghai APS Solar Energy Co. Ltd. to align with project requirements.

Shanghai APS Solar Energy Co. Ltd. is based in the Economics Development Zone of Pudong, Shanghai, China, with a listed address confirming its operational presence in this industrial hub. The company holds a harbor trust tier, indicating a baseline level of verification for its profile on the platform, though no response rate or average response hours are currently recorded.

The supplier specializes in solar water heating systems, as evidenced by the technical details provided for its compact non-pressure model. No additional information about certifications, production scale, or export history is available from the listing, so buyers should request these directly to assess alignment with project needs.
