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 and load size, calculated from the model's registered performance data, or taken directly from the register where it publishes a savings figure. VEU registers this data at the small load (the step-down load for a medium-rated system) and ESS at the medium load, so the two schemes' figures differ for the same zone.
The Neopower NA37-315A is an all-in-one heat pump water heater: a 315 L vitreous enamel-lined steel tank wrapped in a micro-channel heat exchanger, with the R290 heat pump and electric booster built into the same cylindrical cabinet (626 mm diameter, 1979 mm tall, 127 kg net). Declared performance is 2.9 kW heating capacity, 0.67 kW power input and a COP of 4.33 at an ambient of 20 degC DB / 15 degC WB with water heated from 15 to 55 degC, with sound output of 42 dB.
The heat pump operates across an ambient range of -7 to 43 degC. Standard mode (factory default) heats to 60 degC on the heat pump alone; the manual separately recommends a 55 degC setpoint for optimum heat-pump-only efficiency. Hybrid or Electric modes bring the 1.5 kW electric element in to lift outlet temperature to 70 degC. Refrigerant charge is 400 g of R290.
The manual cites AS/NZS 2712, AS/NZS 3498, AS/NZS 3500.4 and AS/NZS 3000 as applicable design and installation standards. Component warranty (Imaca Pty Ltd) is 6 years on the tank, 5 years on refrigeration and electrical parts, all with 2 years labour cover.
