NZ has no equivalent to the Australian STC/VEEC/ESC certificate schemes, so no dollar rebate applies to this model. Its confirmed AU-market equivalent is registered and shown above.
The Emerald Energy EE-HWS-A1-270 is distributed into New Zealand by Ecobulb, working with a network of plumbing and electrical installation partners, under the “Emerald” / “Emerald Pro” name - the same brand and model as the AU-market product, used by 70,000-plus homes across Australasia. A Hitachi-joint-venture DC inverter compressor, DC inverter fan, and microchannel heat exchanger are built into the same cabinet as the 270 L tank.
This variant has no electric heating element, so it runs in Standard, Silent, or Booster mode on the heat pump alone. Standard mode delivers 2.8 kW of heating at a 0.58 kW power input (COP 4.8), and Silent mode drops to 2.0 kW at 0.44 kW input (COP 4.6, 45 dB(A) at 1 m) for quieter running. Without the electric element fitted, the working ambient range is -7 to 43 degrees C.
Ecobulb’s own NZ product page does not publish a separate spec sheet; the figures above are the AU data sheet values for the identical model code.
