About Haining Sunsurf New Energy Technology Co., Ltd - Solar Heaters Supplier in China

Based in China, Haining Sunsurf New Energy Technology Co., Ltd lists five active products within the solar heater segment. The catalogue includes the SC‑C01 separate pressurized solar collector, a separate pressurized solar water heater, the SC‑B01 solar collector designed for balcony installations, an integrative pressurized solar water heater, and an integrative coil solar water heater. Each entry is categorized under solar heating equipment and reflects the company’s focus on pressurized collector systems. The product titles indicate a mix of standalone collectors and integrated water heating units, which are typical configurations in residential and small‑commercial solar heating markets. The supplier’s trust tier is classified as “harbor,” indicating a moderate level of platform verification.

Product Range and Specialties of Haining Sunsurf New Energy Technology Co., Ltd

The catalogue presents five distinct solar heating products: two separate pressurized collectors (SC‑C01 and SC‑B01), two separate pressurized water heaters, and two integrative units that combine collector and storage functions. In the broader solar heater market, collectors are classified as flat‑plate or evacuated‑tube types, with flat‑plate units commonly rated by aperture area (e.g., 1.5 m², 2.0 m²) and evacuated‑tube units measured by the number of tubes (e.g., 40‑tube, 80‑tube). Typical specifications include a glass cover with a solar transmittance of 90 % or higher, copper or aluminum heat‑exchange tubes, and a pressure rating of 0.6 MPa. Water heaters are often rated by thermal capacity (kW) and storage volume (liters), with integrative models frequently offering combined capacities of 2‑4 kW and 150‑250 L tanks. Buyers usually request compliance with IEC 60335‑2‑40 for safety and ISO 9806 performance testing for thermal efficiency.

Trade and Export Information - Haining Sunsurf New Energy Technology Co., Ltd

China is a major exporter of solar thermal equipment, and products such as flat‑plate collectors and pressurized water heaters are routinely shipped to Europe, North America, the Middle East, and Southeast Asia. The relevant HS chapter for solar collectors is 8419, which covers “Parts of machinery for the production of steam, hot water or other liquids.” Export shipments are typically packed in wooden crates or reinforced cardboard boxes, secured on 20‑ft or 40‑ft containers with moisture‑resistant liners. Common Incoterms used by Chinese solar equipment exporters include FOB Hangzhou or CIF destination ports, depending on buyer preference. Importing countries often require CE marking for the European market, UL listing for the United States, and compliance with local building codes that reference ISO 9806 test results.

Sourcing from Haining Sunsurf New Energy Technology Co., Ltd - Buyer Guidance

When sourcing pressurized solar collectors or integrative water heaters from this supplier, buyers should request the latest product data sheet that lists aperture area, thermal efficiency (ISO 9806), pressure rating, and material composition (glass type, tube material). Verify that the unit has undergone IEC 60335‑2‑40 safety testing and that a CE or UL certification is available for the intended market. Samples or factory‑tested units are advisable for performance verification, especially to confirm heat‑transfer efficiency under local climate conditions. Buyers should also confirm packaging dimensions, container loading plans, and the supplier’s standard lead time, which for Chinese solar equipment typically ranges from 30 to 60 days after order confirmation.

What types of solar heating products does Haining Sunsurf list?

The supplier lists five items: two separate pressurized solar collectors (SC‑C01 and SC‑B01), two separate pressurized solar water heaters, an integrative pressurized solar water heater, and an integrative coil solar water heater.

Are the collectors suitable for balcony installations?

Yes, the SC‑B01 model is specifically described as a solar collector for balcony systems, which usually has a compact frame and a smaller aperture area suited for rooftop or balcony mounting.

What efficiency standards should I look for?

Buyers typically request ISO 9806 test reports that show thermal efficiency values, which for flat‑plate collectors from China generally range from 45 % to 70 % under standard test conditions.

Which certifications are commonly required for solar water heaters?

Commonly required certifications include IEC 60335‑2‑40 for safety, CE marking for the EU, and UL listing for the US. Buyers should ask the supplier to provide copies of these certificates before shipment.

What is the usual packaging for these solar heating units?

Export packs normally consist of reinforced wooden crates or heavy‑duty cardboard pallets, with each unit secured against vibration and moisture. The crates are loaded into 20‑ft or 40‑ft containers using standard container stowage plans.

What lead time and minimum order quantity can I expect?

Chinese solar equipment manufacturers typically quote a lead time of 30‑60 days after order confirmation. Minimum order quantities vary by model but often start at a single unit for specialized collectors, with larger batch discounts for orders of ten units or more.

Which HS code applies to these products?

Solar collectors and related water heating equipment fall under HS chapter 8419, which covers “Parts of machinery for the production of steam, hot water or other liquids.”

How can I request a sample or technical data?

Buyers should send a formal request for a product data sheet, performance test report, and, if needed, a functional sample. The supplier will usually arrange shipment under the buyer’s chosen Incoterm, such as FOB or CIF.
