Reclaim Energy CO2 315L - NZ
AS/NZS 4234 energy savings (AU equivalent)
83%
vs the standard's reference electric storage water heater, VEU Zone 4, based on the AU-registered performance of the Reclaim Energy CO2 315L (same brand and physical unit; NZ site confirms the glass-lined tank as REHP-CO2-315GL, one of the exact register model codes already recorded for the AU product) — not tested against AS/NZS 4234 as a NZ product itself.

What customers say
Sourced from EnergyAE's HPWH customer-sentiment dataset (public review sites and forums). A small, self-selected sample — not a representative survey.
“Sanden Ecoplus and Reclaim are the best systems out there. These are both split systems and do not need an element.”
“If you are willing to spend more look at Reclaim - outstanding performance but a split system.”
WWHB · Geekzone
“So far it has been working as advertised, seems to recover quick after hot water use, faster than the element did and is quiet.”

The Reclaim Energy CO2 315L is a split-system heat pump water heater sold under the same brand and model in New Zealand and Australia, distributed in NZ by Apricus Eco: an outdoor CO2 (R744) heat pump unit, with compressors manufactured in Japan, paired with a 315 L storage tank (available in glass-lined or stainless steel). The heat pump delivers up to 6.0 kW of heating with a rated power input of 2.3 kW, and operates from -10 to 43 degrees C ambient, suiting cold-climate NZ installations.
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. Reclaim Energy NZ markets the system on a 2 to 3 year payback versus an electric-element tank of the same capacity, using around 3 kWh of electric input against roughly 15 kWh for an equivalent electric system.
The NZ site names the glass-lined tank variant REHP-CO2-315GL, one of the exact register model codes already confirmed for the AU-registered product, so this is recorded as a direct market match rather than a rebadge.
