Hot water heat pumps NZ
A hot water heat pump heats your water with heat taken from the outside air, instead of an element in the cylinder. EECA’s installation guide says these systems often use 60 to 70% less electricity than a standard electric hot water cylinder, and hot water is around a third of the average New Zealand home’s energy use. This section has hot water heat pumps from Haier and Panasonic, and Panasonic Aquarea air to water heat pumps.
Which type
| Type | What we list |
|---|---|
| All-in-one (monoblock) | Haier monoblock units, with the heat pump and cylinder in one unit: 200 and 250 L (2.0 kW, including models with a 15 A 3-pin plug) and 330 L (2.8 kW, hardwired). |
| Split system | A separate outdoor heat pump connected to an indoor or outdoor cylinder. Haier’s 280 L split system is sold as a set, or as the heat pump module and cylinder separately. |
| CO2 | Panasonic CO2 hot water heat pumps, which use carbon dioxide (R744), a natural refrigerant. |
| Air to water | Panasonic Aquarea monobloc units from 5 to 16 kW heat water for underfloor heating or radiators, and can also heat a hot water cylinder. |

Hot water heat pump prices
The price on each product is for the unit only, incl. GST. Installation by your plumber and electrician is extra and depends on the old system, the pipe runs and the wiring, so ask them for a quote once you have chosen a model.
Is one right for your home?
- Household size: EECA says they suit medium to large households with steady hot water use. With one or two people, or very little hot water use, the savings are unlikely to cover the higher purchase price.
- Timing: the best time to switch is when your old cylinder needs replacing. EECA notes that replacing a water heater that still works well is unlikely to pay for itself.
- Size: an undersized system runs harder and may not keep up, and EECA says its extra running costs generally outweigh the cost of a slightly larger unit.
- Location: the outdoor unit makes some noise, typically 40 to 55 dB, so put it away from bedrooms.
Installation
Installing a hot water heat pump is plumbing and electrical work, so it needs a registered plumber and a registered electrician. Split systems joined by refrigerant pipe also need an installer certified to handle refrigerant. Ask your installer to check your wiring and water pressure before you order.
Common questions
How much electricity does a hot water heat pump save?
EECA’s guide says they often use 60 to 70% less electricity than a standard electric cylinder. Actual savings depend on your climate, how much hot water you use and how well the system is installed and serviced.
Do they work in winter?
Yes, but they are less efficient in cold weather, because there is less heat in the air and the outdoor unit has to defrost. Some models also have a backup element for very cold days.
Can I plug it in?
Some Haier monoblock models come with a 15 A 3-pin plug and need a 15 A outlet. Others are hardwired by an electrician. The product name says which.
