Heat Pump Cylinders to Suit Any Home
The heat pump systems we stock are all-in-one (integrated) units — the heat pump sits on top of the cylinder as a single, simple-to-install package. We carry sizes to suit every household:
Compact (around 180–200L). Best for smaller homes or 2–3 people. Examples: the Haier 200L and the inverter-driven Gree WHIO 200L.
Family size (250–280L). Our most popular range, ideal for 3–4 people. Examples: the Apricus All-In-One 260L, the Gree WHIO 270L and Haier 250L, plus premium integrated options like the Rheem AmbiPower 280e and Rinnai HydraHeat 275L.
Large household (330–340L). For bigger homes or high hot-water use. Examples: the Haier 330L and the Rinnai HydraHeat 340L.
Lowest-emission option (R290). If reducing emissions matters most, the Thermann 270L R290 uses a natural propane refrigerant with a very low global-warming potential that also performs well in New Zealand conditions.

Why Are Heat Pumps The Best Water Heating Option?
Heat pump hot water cylinders are the most energy-efficient way to heat water in a New Zealand home. A heat pump water heater draws warmth from the surrounding air and uses it to heat the tank — so it uses up to 70% less electricity than a standard electric cylinder, cutting both your power bill and emissions. They cost more upfront but deliver strong long-term savings, especially for larger households, and suit most NZ homes — here’s why a heat pump hot water system is a smart upgrade for Kiwi homes.
How Do Heat Pumps Work?
A heat pump hot water system is a highly efficient and eco-friendly option for heating the water in your home. This system uses a heat pump to take heat from the air and transfer it to the water in the cylinder. This means even in colder temperatures, the heat pump can still effectively heat the water, making it a reliable and efficient source of hot water.
Compared to traditional electric or gas water heating systems, a heat pump hot water system is much more energy efficient, and it also has lower greenhouse gas emissions. The use of advanced controls in the system also offers you more control over your hot water heating, allowing you to manage the way your heating operates.
Running Costs & Savings
Water heating is around 30% of a typical New Zealand power bill. A heat pump hot water system runs at roughly 300–400% efficiency — for every unit of electricity it uses, it moves three to four units of heat into the tank. In practice that’s up to 70% less electricity than a standard electric cylinder for the same hot water.
The trade-off is a higher purchase price, so the saving pays the system back over time rather than immediately — the more hot water your household uses, the faster that happens. Compare it against a straight replacement on our electric hot water cylinders page before deciding. Finance is available if you’d rather spread the upfront cost.
Installation & What’s Included in Your Fixed Price
Every install is quoted at a fixed price — no surprises. A heat pump hot water installation typically costs $6,000 – $9,500 incl GST installed, depending on the model, whether it replaces an existing cylinder, and site access. Heat pumps need a spot with good airflow and a condensate drain — we’ll confirm placement on site. Your fixed price includes supply of the cylinder, removal & disposal of the old unit, installation by a registered plumber, electrical connection by a certified electrician, all valves & fittings, seismic restraint and a code of compliance (if applicable).
