Why Mitsubishi Electric EcoCore AP Takes the Top Spot
The EcoCore AP Series has been the best-selling heat pump brand in NZ for good reason. The 3D i-See Sensor detects where people are in the room and directs airflow accordingly, which saves energy and keeps you comfortable. It runs quietly at just 19dB on the lowest setting (quieter than a whisper), heats effectively down to -15 degrees Celsius outdoor temperature, and comes with a 6-year manufacturer warranty. For the price point, nothing else matches this combination of features.
The Premium Pick: Daikin US7
If energy efficiency is your top priority, the Daikin US7 is the most energy efficient heat pump in NZ. It achieves a 7-star energy rating, which translates to noticeably lower power bills compared to a 5-star unit. The US7 uses Daikin’s swing compressor technology for smoother, more efficient operation and includes built-in Wi-Fi control via the Daikin Mobile Controller app. It costs more upfront, but for homes where the heat pump runs 6+ hours a day through winter, it pays for itself over time.
Best Heat Pumps by Type
Not every room suits a standard wall-mounted unit. Here is a breakdown of the best heat pump brands in NZ for each type of installation.
Best Wall Mounted Heat Pumps
Wall-mounted split systems are the most popular choice for NZ homes. They are affordable, efficient, and suit most living rooms and bedrooms.
| Model | Standout Feature | Noise Level (Indoor) | Wi-Fi |
|---|---|---|---|
| Mitsubishi EcoCore AP | 3D i-See Sensor | 19 dB | Optional (Wi-Fi adapter) |
| Daikin US7 | 7-star efficiency | 19 dB | Built-in |
| Daikin Cora FTXM | Great mid-range value | 20 dB | Optional |
| Fujitsu KMTC | Human sensor | 20 dB | Built-in |
Best Floor Mounted Heat Pumps NZ
Floor consoles sit at ground level, making them ideal for rooms with low windows, conservatories, or anywhere wall mounting is not practical. They also deliver heat at floor level, which many people find more comfortable than a wall unit blowing warm air across the top of the room.
- Mitsubishi Electric SRF Series – The most popular floor console in NZ. Compact design, quiet operation, and the same proven reliability as their wall units. Available in 2.5kW to 5.0kW.
- Fujitsu ASTG Floor Console – Slightly more affordable than the Mitsubishi, with good energy ratings and a slim profile that sits flush against the wall.
- Panasonic Floor Console – Budget option that still delivers reliable heating and cooling, with nanoe X air purification built in.
Best Ducted Heat Pumps NZ
Ducted systems are hidden in the ceiling and deliver heating and cooling to every room through vents. They are the most expensive option but provide the most consistent whole-home comfort.
- Daikin FDYAN Ducted – Industry leader for ducted systems in NZ. Inverter technology, zone control capability, and reliable performance. Available from 7.1kW to 20kW+.
- Mitsubishi Electric PEAD Series – Excellent build quality and proven reliability. Slightly quieter than Daikin in most installations.
- Fujitsu ARTG Ducted – Strong competitor with good pricing and solid warranty support through their NZ distributor.
Best Multi-Room Heat Pump Systems
Multi-split systems use one outdoor unit connected to multiple indoor units, so you can heat or cool several rooms independently without needing multiple outdoor units cluttering your property.
- Mitsubishi Electric Multi Split (MXZ Series) – Supports 2 to 8 indoor units from a single outdoor unit. Mix and match wall, floor, and ceiling cassette units.
- Daikin Multi Split – Similar flexibility with Daikin’s efficiency advantages. Good option if you already prefer Daikin units.
What to Look for When Choosing a Heat Pump
With so many models available, it helps to know which specifications actually matter for NZ conditions. Here are the key factors we advise our customers to consider.
Energy Star Ratings (EECA Labels)
In New Zealand, heat pumps carry an Energy Rating Label regulated by EECA (Energy Efficiency and Conservation Authority). More stars means lower running costs. A 6-star unit typically uses 20-30% less electricity than a 4-star unit of the same capacity. Look for at least 4 stars for heating, as this is the rating that matters most in NZ’s climate.
Heating Capacity (kW)
The kW output tells you how much heat the unit can deliver. Bigger is not always better. An oversized unit cycles on and off frequently, reducing efficiency and comfort. An undersized unit runs constantly and never reaches your desired temperature. Getting the size right is essential, which is why a proper assessment by a qualified installer matters more than guessing from an online calculator.
Noise Levels
Indoor noise levels between 19-22 dB are considered whisper-quiet and suitable for bedrooms. Outdoor unit noise matters too, especially in close-proximity housing. Check both the indoor and outdoor dB ratings, particularly if your outdoor unit will be near a neighbour’s bedroom window.
Warranty
NZ warranty periods vary by brand:
- Mitsubishi Electric: 6 years parts and labour
- Daikin: 5 years parts and labour (6 years if installed by a Daikin Specialist Dealer)
- Fujitsu: 6 years parts and labour
- Panasonic: 5 years parts and labour
- Hitachi: 5 years parts and labour
Always check that your installer is authorised by the manufacturer, as some warranties are voided if installation is not done by a qualified professional.
Wi-Fi Control
Most premium models now offer Wi-Fi connectivity, letting you control your heat pump from your phone. This is genuinely useful for turning your heat pump on before you get home, so the house is warm when you walk in the door. Some brands include Wi-Fi as standard (Daikin US7, Fujitsu KMTC), while others require an optional Wi-Fi adapter (Mitsubishi Electric, around $150-$250 extra).
Brand Availability and Servicing
Stick with brands that have strong NZ distribution and servicing networks. Mitsubishi Electric, Daikin, and Fujitsu all have established NZ operations, which means parts are readily available and warranty claims are handled locally. Cheaper imported brands may save money upfront but can be a headache when something goes wrong.
How to Size a Heat Pump for Your Home
Getting the right size heat pump is one of the most important decisions. Here is a rough guide to get you started, but we always recommend a professional assessment for an accurate recommendation.
Quick Sizing Formula
A general rule of thumb: Room area (m2) x 0.12 to 0.15 kW = approximate heating capacity needed. For example, a 30m2 living room needs roughly 3.6 to 4.5 kW of heating capacity.
This varies based on insulation quality, ceiling height, window type and orientation, and how exposed the room is to wind. Wellington homes in particular often need extra capacity due to persistent wind and higher moisture levels.
| Room Size (m2) | Well Insulated | Average Insulation | Poorly Insulated / Exposed |
|---|---|---|---|
| 15 – 20 m2 | 2.0 – 2.5 kW | 2.5 – 3.0 kW | 3.0 – 3.5 kW |
| 20 – 30 m2 | 2.5 – 3.5 kW | 3.5 – 4.5 kW | 4.5 – 5.0 kW |
| 30 – 45 m2 | 3.5 – 5.0 kW | 5.0 – 6.0 kW | 6.0 – 7.1 kW |
| 45 – 65 m2 | 5.0 – 6.0 kW | 6.0 – 7.1 kW | 7.1 – 8.0 kW |
| 65+ m2 (open plan) | 6.0 – 8.0 kW | 8.0 – 10.0 kW | Ducted or multi-split recommended |
Wellington tip: If your home is exposed to southerlies or sits on a hillside, go one size up from the “average insulation” column. The wind chill factor and moisture in Wellington homes means your heat pump works harder than the same unit in a sheltered Christchurch property.
Heat Pump Costs in NZ
Here is what you can expect to pay in 2026 based on industry averages across New Zealand. These prices include the unit and professional installation.
| Heat Pump Type | Unit Cost Range | Installation Cost Range | Total Installed |
|---|---|---|---|
| Wall mounted (single room) | $1,800 – $3,500 | $500 – $1,500 | $2,300 – $5,000 |
| Floor / console | $2,500 – $4,500 | $500 – $1,200 | $3,000 – $5,700 |
| Ducted (whole home) | $6,000 – $15,000+ | $2,000 – $5,000 | $8,000 – $20,000+ |
| Multi-split (2-4 rooms) | $5,000 – $12,000 | $2,000 – $5,000 | $7,000 – $17,000 |
These are industry average prices across New Zealand. Your actual cost depends on the brand, model, capacity, installation complexity, and whether any electrical upgrades are needed. For exact pricing tailored to your home, contact Weka Electrical for a free quote.
What Affects Installation Cost?
Installation pricing varies depending on several factors:
- Back-to-back installation (indoor and outdoor units on the same wall) is the simplest and cheapest.
- Piping runs – longer distances between indoor and outdoor units increase labour and materials.
- Multi-storey homes – working at height or running pipes through floors adds complexity.
- Electrical work – if your switchboard needs a dedicated circuit, this adds to the cost. All heat pumps require electrical work by a registered electrician.
- Removal of old unit – if you are replacing an existing heat pump, removal and disposal is usually included.

Frequently Asked Questions
What is the most efficient heat pump in NZ?
The Daikin US7 currently holds the highest energy rating available in NZ at 7 stars for heating. It uses approximately 20-30% less electricity than a standard 4-5 star heat pump of the same capacity. The Mitsubishi Electric EcoCore AP is a close second at 6 stars, offering excellent efficiency at a lower price point.
How long do heat pumps last in NZ?
A quality heat pump from a reputable brand typically lasts 12 to 20 years with proper maintenance. Regular cleaning of filters (every 2-4 weeks during heavy use) and a professional service every 1-2 years helps extend the lifespan. Units installed in coastal areas may need more frequent servicing due to salt air corrosion.
Which brand has the best warranty in NZ?
Mitsubishi Electric and Fujitsu both offer 6-year warranties in NZ, which is the longest standard warranty among the major brands. Daikin offers 5 years as standard, extending to 6 years when installed by an authorised Daikin Specialist Dealer. Always ensure your installer is qualified, as incorrect installation can void manufacturer warranties.
Do I need an electrician to install a heat pump?
Yes. In New Zealand, heat pump installation requires both a registered electrician for the electrical connections and wiring, and a qualified refrigeration technician for the refrigerant lines. At Weka Electrical, our team handles both aspects, so you only need to deal with one company. Attempting a DIY installation is not only unsafe but is also illegal for the electrical and refrigerant components.
What size heat pump do I need for a 3-bedroom house?
For a single heat pump in the main living area of a 3-bedroom house, you typically need a 5.0 to 7.1 kW unit depending on the open-plan area size and insulation quality. If you want to heat individual bedrooms as well, a multi-split system with 2.0-2.5 kW units in each bedroom is the most efficient approach. A ducted system is another option for whole-home heating, typically requiring 10-14 kW capacity.
Are heat pumps worth it in Wellington?
Absolutely. Wellington’s climate makes heat pumps one of the most cost-effective heating options available. A modern heat pump produces 3 to 5 kW of heat for every 1 kW of electricity consumed, making them 300-500% efficient compared to electric heaters which are only 100% efficient. Even accounting for Wellington’s wind and moisture, a heat pump will typically save you 30-50% on heating costs compared to plug-in electric heaters.
