Gree WHIO Hot Water Heat Pumps Christchurch
Looking for a more efficient way to heat your hot water in Christchurch? The Heat Pump People now offer the new Gree WHIO external hot water heat pump cylinders as the go‑to solution for most homes wanting lower running costs and modern, smart control.
What Is the Gree WHIO Hot Water Heat Pump?
The Gree WHIO is an integrated external hot water heat pump system that uses inverter technology and eco‑friendly R290 refrigerant to deliver high‑temperature hot water with excellent energy efficiency. It is designed to replace traditional electric cylinders or outdoor gas water heaters, freeing up indoor space and reducing energy use.
Why Choose A WHIO Hot Water Heat Pump in Christchurch?
- High efficiency (COP around 5.4): Under test conditions, WHIO delivers about 2.3 kW of heating while using roughly 0.43 kW of power, giving a class‑leading COP of about 5.4 and helping to significantly reduce hot water running costs.
- 7‑year parts and labour warranty: The system is backed by a comprehensive 7‑year warranty in New Zealand, providing long‑term peace of mind.
- Wi‑Fi and smart control: WHIO connects to the Gree Wi‑Fi app and includes a smart wired controller that can be relocated inside for convenient operation and scheduling.
- External installation: Designed to be installed outside, WHIO is ideal for replacing gas califonts or older external hot water systems common around Christchurch.
- Eco‑friendly R290 refrigerant: R290 is a natural refrigerant with very low global warming potential (GWP of about 3) and zero ozone depletion potential, while still allowing water temperatures of up to about 70°C.
How Does the Gree WHIO Help Lower Hot Water Costs?
Traditional electric cylinders use a lot of power to heat water directly, while WHIO uses heat pump technology to move heat from the outdoor air into the water. With a COP of around 5.4, the WHIO system can use up to around 70% less energy than a standard electric hot water system, especially when combined with intelligent energy‑saving modes like “Sunflower” that choose the warmest part of the day to operate.
What Smart Features Does WHIO Offer?
- Intelligent “Sunflower” mode: Uses AI to select the best time of day to heat the water for maximum efficiency, improving energy conservation by up to around 10%.
- Holiday mode: Avoids heating water while you are away but ensures you come home to a full tank of hot water.
- Boost mode: Speeds up recovery if hot water demand suddenly increases, such as when you have guests staying.
- Sterilisation program: The smart controller can schedule heating to 70°C to help reduce bacteria in the cylinder, supporting healthier hot water.
Is The Gree WHIO Suitable for My Household?
The WHIO range includes 200‑litre and 270‑litre tank options, typically suited to households of about three to five people, depending on usage. The crystal titanium enamel tank is designed for durability, with multi‑layer anti‑corrosion protection and extensive testing for acid resistance and pressure performance. A consultation with The Heat Pump People can confirm which size suits your hot water use and property layout.
Is The Gree WHIO a Good Option for New Builds and Gas Replacements?
Yes. Because WHIO is an external unit and uses low‑GWP R290 refrigerant, it fits well with new all‑electric builds and projects looking to move away from gas hot water. It is particularly attractive for Christchurch homeowners wanting to reduce emissions, integrate with solar, or future‑proof their home before upcoming building and energy efficiency changes.
