Certificate counts are computed from the model's registered performance data using the current regulated equations. A lodged claim depends on the specific installation, household size, and the scheme rules in force at creation. Energy savings % is against the AS/NZS 4234:2021 reference electric storage water heater for that zone, medium household, calculated from the model's registered performance data.
The Rinnai Enviroflo EHPA250VMA is an all-in-one heat pump water heater: a single vertical cabinet with the fan coil unit and compressor mounted above a 250 L storage cylinder. Heat exchange from refrigerant to water runs through a plate heat exchanger and circulation pump rather than a direct wrap-around coil, and R290 (270 g charge) is the refrigerant across the range. The unit is rated at 5.20 kW heat output with a COP of 7.22 at 32.6 degrees C ambient and 21.1 degrees C cold water inlet, and it operates down to -1 degrees C ambient before the 2.4 kW electric element takes over. The refrigeration module is factory-wired to 1.0 kW; total rated input to be wired by the installer (module plus element) is 3.4 kW.
Net weight is 123 kg (400 kg filled), cylinder height 1847 mm, diameter 627 mm, unit width 675 mm, with a sound level of 48 dB(A). The manual covers four physical variants of this same 250 L cylinder: EHPA250VMA, EHPA250VMAH, EHPA250VMAW and EHPA250VMAWH, sharing identical heat pump performance and dimensions.
This entry does not cover the plain EHPA250VM (no VMA suffix) register code, which the source manual explicitly excludes (“this manual does NOT apply to any other models”).
