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

The Sunrain all-in-one heat pump water heater is an air-source unit designed for residential domestic hot water production, extracting renewable thermal energy from ambient air to achieve operating efficiencies substantially above conventional electric resistance or gas-fired systems. The system integrates compressor, evaporator, condenser and enamel-lined storage cylinder into a single cabinet, eliminating the need for separate outdoor and indoor units. Key performance claims from the supplier include coefficient of performance levels that can reduce energy consumption by up to 80% relative to traditional gas boiler or electric water heater baselines, with maximum water temperature output of 75 degrees Celsius maintained through variable frequency compressor modulation.

At the core of the unit is a variable-frequency rotary compressor (brand not specified in source data) that adjusts speed in response to indoor and outdoor temperature conditions, a control strategy intended to optimise part-load efficiency and reduce acoustic output. The water tank interior is enamel-coated steel, a standard domestic hot water vessel construction that provides corrosion resistance against chlorinated municipal supplies. Thermal insulation consists of high-density polyurethane foam injected between the tank and outer casing, with the supplier noting this limits standby heat loss. The air-side heat exchanger employs hydrophilic-coated aluminium fin stock on copper tubing, a typical configuration for humid climates where condensate drainage and corrosion resistance are relevant. Reverse-cycle defrost is managed via a four-way reversing valve rather than resistive electric defrost, reducing energy penalty during frost removal cycles.

Primary applications are single-family and small multi-family residential installations where space constraints favour integrated rather than split-system architectures. The 75 degree Celsius maximum setpoint suits households with elevated temperature requirements or those in colder climate zones where lower source air temperatures degrade heat pump performance. Buyers should confirm whether the rated capacity corresponds to standard EN 16147 or similar test conditions, as manufacturer capacity figures often reflect 15 degrees Celsius air / 10 degrees Celsius water inlet conditions that may not translate to peak load scenarios. The supplier states 100% factory testing but does not detail specific test protocols or third-party certification status. Incoterms, minimum order quantities, lead times and warranty terms are not provided in the listing data and must be confirmed directly with Guangdong Sunrain Air Source Energy Co.,Ltd.

Guangdong Sunrain Air Source Energy Co.,Ltd. is located at No.73 De Fu Road, Xing Tan Town, Foshan City, Guangdong Province, 528000, placing it within China's concentrated appliance manufacturing corridor between Foshan and Guangzhou. The supplier holds a Harbor trust tier classification, which in marketplace terms indicates a baseline verification level; however, the response rate is listed at 0.00% with zero average response hours recorded, suggesting either a new listing, dormant account, or data capture anomaly. No information is provided regarding years in operation, factory floor area, employee count, annual turnover, or export markets served.

The listing presents the company as a manufacturer of domestic heat pump water heaters with emphasis on integrated all-in-one designs rather than split-system or commercial-scale products. No original equipment manufacturing relationships, distributor networks, or project references are disclosed. The supplier does not state ISO 9001, ISO 14001, CE marking, or other certification status in the provided data. Buyers should independently verify business registration, factory audit status, and whether the company maintains in-house compressor testing facilities or relies on component sourcing. The product description focuses on consumer-oriented efficiency claims rather than technical documentation suited to commercial procurement due diligence.
