Import All In One Heat Pump Top Discharge — Buy in wholesale FOB from Supplier in China

The Guangdong Sunrain Air Source Energy Co.,Ltd. All In One Heat Pump Top Discharge is an integrated domestic hot-water system that draws air through a top-mounted duct connection, exhausting conditioned air vertically rather than horizontally from the cabinet sides. Like its counterpart, it reaches 75 degrees C and houses an enamel-lined tank with Blue Shield protection up to 2.0 mm thickness, factory-tested construction, and an intelligent controller. The top-discharge architecture suits installations where side clearance is restricted or where ducting to outside space is preferred to avoid cooling the plant room.

The unit shares the all-in-one format with internal storage, reverse-cycle defrost via a 4-way valve, and high-density foam insulation. A sterilisation function is mentioned, likely a periodic pasteurisation cycle to control legionella, though the trigger temperature and frequency are not detailed. The top air in/out arrangement with duct connection is the distinguishing layout feature, a format that can simplify compliance with building regulations requiring mechanical ventilation or condensation management in unheated spaces. Enamel water tanks with fluorine-free insulation layers are standard in this product class for potable water safety and environmental registration.

Target buyers include plumbing merchants, social-housing maintenance contractors, and developers of multi-unit residential projects where ducted exhaust prevents localised overcooling. The top-discharge configuration is particularly relevant for basement or utility-cupboard siting in temperate climates. Importers should confirm airflow rates, external static pressure capability for ducted installations, and whether the sterilisation cycle is adjustable or fixed. Refrigerant charge, tank volume, and heating capacity at the design ambient must also be validated against project load calculations.

Guangdong Sunrain Air Source Energy Co.,Ltd. operates from No.73, De Fu Road, Xing Tan Town, Foshan City, Guangdong Province, 528000, China. The supplier is listed at harbor trust tier with a response rate of 0.00 percent and no recorded average response hours. This profile pattern indicates that buyers should not assume rapid quotation turnaround and should plan sourcing timelines with contingency for delayed communication.

The company presents itself as a manufacturer of air-source heat pump water heaters with two distinct all-in-one variants, standard and top-discharge. No export turnover, employee count, factory floor area, or certification list appears in the source data. Buyers evaluating this supplier for project tenders should request audited accounts, manufacturing licence documentation, and reference installations in comparable climates before adding the firm to an approved vendor list.
