The Haier HP300S2-F7 is a split-system heat pump water heater: a separate outdoor heat pump unit (model EHP50S2-F7) connects by pre-charged R32 refrigerant piping (1/4 inch by 3/8 inch pair-coil, UNF flare fittings) to an indoor 300 L nominal (276 L cylinder volume) tank with an internal condenser coil (model THP300S2-F7). The heat pump unit measures 780 mm wide by 286 mm deep by 545 mm tall and weighs 30 kg net; the tank measures 1694 mm tall and weighs 86 kg net.
The assembled system is rated at 4.3 kW heating capacity with a 1.7 kW rated total power input, and operates from -15 to 45 degrees C ambient, an unusually wide cold-climate range for this brand’s range. It produces 52 dB(A) at 1 m and delivers hot water at a default 55 degrees C, adjustable from 35 to 75 degrees C with the 2.6 kW electric element engaged. Refrigerant charge is 930 g of R32 (maximum 930 g for up to 5 m pipe run).
No COP figure or product certification number is stated in the manual sighted; the manual notes COP and noise data were tested in Haier’s own lab. This unit is sold in Australia and New Zealand under the Haier brand.
