Midea Split 280L (RSJ-23/300RDN3-B) - NZ

The Midea RSJ-23/300RDN3-B is a split-configuration heat pump water heater sold in New Zealand (Trade Depot markets it as the “300L” split system; NZ Depot lists the same code against a 280L nominal size, following the same nominal-vs-physical naming convention as Midea’s integral 280L/300L unit). The outdoor heat pump unit is rated at 2.8 kW heating capacity, measures 804 mm wide, 327 mm deep and 555 mm tall, and the indoor tank carries a 2.0 kW electric booster element.

This is a different model code from the integral RSJ-23/300RDN7-L2 (WiFi) unit already recorded separately, and from the AU-registered Midea models, so no AU-equivalent match is recorded. Refrigerant, COP, sound level, ambient operating range and warranty are not published on the retailer listings sighted. A 200L split variant is also advertised by NZ retailers (Trade Depot, The Warehouse) but its exact model code could not be confirmed - Trade Depot’s own site blocks automated fetching and no other retailer listing carrying the code was found.
