Import 300l Solar Water Heater — Buy in wholesale FOB from Supplier in China

The 300l Solar Water Heater from Dezhou BTE Solar Co., Ltd. uses a double-layer pressurised tank with natural thermosyphon circulation between flat plate collectors and the storage vessel. Heat transfer fluid warms in the collector loop and transfers thermal energy to potable water in the inner tank, keeping domestic hot water under pressure for standard tap and shower delivery. The system is roof-mounted and relies on passive circulation, eliminating pump energy use during normal operation. Tank capacity is 300 litres, suited for residential households or small commercial hot water demand.

Flat plate collectors are the typical heat source for this thermosyphon design, though the listing does not specify absorber material, glazing type, or insulation thickness. Standard industry construction uses selective coating on copper or aluminium absorbers, tempered glass glazing, and polyurethane foam insulation. The pressurised inner tank is typically enamelled steel or stainless steel to resist corrosion. Natural circulation depends on proper collector tilt angle and pipe routing, so installation geometry is critical to performance.

Buyers are typically homeowners, housing developers, or small hospitality operators in sunny climates seeking reduced electricity or gas bills for water heating. The roof-mount design suits pitched roofs with adequate structural load capacity. You should confirm collector area in square metres, tilt angle recommendation for your latitude, and whether the supplier provides mounting frames for different roof types. Also verify working pressure rating, freeze protection method, and compatibility with local water chemistry.
