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 Reclaim Energy CO2 315L is a split-system heat pump water heater: an outdoor CO2 (R744) heat pump unit paired with a 315 L storage tank (323 L physical volume). The single heat pump unit across the range delivers up to 6.0 kW of heating with a rated power input of 2.3 kW, and operates in ambient temperatures from -10 to 43 degrees C, so it suits cold-climate installations where many integral units derate.
R744 is a natural refrigerant with a GWP of 1, and the system delivers hot water at 63 degrees C without an electric backup element. The 315 L tank is offered in glass-lined and stainless-steel versions; all share the same heat pump and register performance.
The same physical product is registered under a number of model codes (tank material, colour, and rebrand variants). Certificate values below are the same across those variants.
