Who is it a good fit for?
- Efficiency-focused buyers wanting the highest COP available — COP 5.41 is the best in New Zealand for an integrated system.
- Solar PV homes — Sunflower AI mode identifies the warmest part of the day to maximise solar self-consumption.
- Eco-conscious buyers — R290 (GWP 3) with inverter compressor for maximum efficiency.
- Those wanting 70°C sterilisation capability — built-in legionella kill mode.
- Medium households (TD200) — 206L suits 3–4 people.
- Larger families (TD270) — 270L suits 4–5 people.
Review
Performance & Efficiency:
The Gree WHIO arrives as the highest-COP integrated hot water heat pump in New Zealand at 5.41 — though tested at 20°C/15°C ambient with water from 10°C to 55°C, which is broadly comparable to the NZ standard test conditions used by other brands. The purpose-designed inverter compressor and external microchannel heat exchanger contribute to the class-leading efficiency.
Features:
- The Sunflower mode is particularly clever: it uses AI to identify the warmest part of the day to heat water, optimising for solar PV or simply maximising heat pump COP.
- The crystal titanium enamel tank: has been tested for 1,080 hours of acid/corrosion resistance).
Supply & Service Network:
Gree is the world’s largest residential air conditioning manufacturer and has invested 15 years in R290 technology. The 7-year full parts and labour warranty matches good practice in the market. Gree is distributed in New Zealand by Realcold.
