Reliable, energy-efficient heat pump hot water cylinders in Wellington supplied and Plumbspec. Built for NZ homes and year-round comfort.
Why Heat Pump Hot Water Systems Make Sense in Wellington
Heat pump hot water cylinder systems are quickly becoming the best option for Wellington homes looking to move away from gas or outdated electric cylinders. A heat pump water heater uses heat from the outside air to warm your water, using far less electricity than a standard electric hot water cylinder. With rising energy costs and a growing shift toward all-electric homes across NZ, a hot water heat pump cylinder offers long-term savings, lower emissions, and reliable performance even during colder Wellington winters.

Frequently Asked Questions
How much does a hot water heat pump cost in Wellington?
The cost of a hot water heat pump in Wellington depends on the size of the cylinder, the brand, and whether any electrical upgrades are needed. In most homes, pricing usually includes the unit, labour, and commissioning. Larger households may need a bigger heat pump hot water cylinder (like 300L), which affects the total. We’ll always look at your hot water usage, site access, and external placement first so you get the best hot water heat pump system for your home, not an oversized or undersized setup.
Do you offer hot water heat pump installation as well as supply?
Yes, we offer full supply and installation across Wellington. That means you can buy the system through us and we handle the complete install, including positioning the external unit, electrical coordination, and setup. We’ll recommend the right heat pump water heater system based on your household size, daily usage, and the layout of your property. It’s a straightforward process, and you’ll have one team managing the job from start to finish.
What brands do you supply?
We supply a range of trusted heat pump hot water cylinders suited to Wellington conditions and wider NZ homes. This includes brands like Rinnai, Carrier, and Rheem, or any other brand you want installed. Each brand has different strengths, so we’ll guide you through the pros and cons in plain language. If you’re looking for the best performance for high usage, or you want something reliable and cost-effective, we’ll recommend a system that fits.
Are hot water heat pumps really cheaper to run than gas?
For many Wellington homes, yes. heat pump hot water cylinders are highly efficient because they use ambient air to heat water, rather than generating heat the hard way like a traditional electric cylinder. A well-sized hot water heat pump can produce several times more hot water per unit of electricity than standard systems. With gas costs rising and more households moving to all-electric setups, switching to heat pump hot water cylinders can reduce running costs over the long term, especially for families.
What size heat pump hot water cylinder do I need?
Choosing the right heat pump hot water cylinder comes down to how many people are in the home and how you use hot water day to day. A smaller household may suit a 190L cylinder, while families and high-usage homes often need 300L to avoid running short. We’ll talk through your usage patterns, peak demand times, and future plans (like extra bathrooms). Correct sizing helps your system run efficiently and keeps your hot water reliable all year.
Do heat pump hot water systems work well in Wellington winters?
Modern heat pump hot water systems are designed to perform well in NZ climates, including Wellington’s cold and windy winter days. While the system is more efficient in milder temperatures, quality units still deliver reliable hot water year-round. On the coldest days, some systems may use a small amount of backup electric heating, but when sized and installed correctly, most households won’t notice any difference in comfort. The key is choosing the right system for your home and location.
Where does the external unit go, and will it be noisy?
The external component of a heat pump hot water system needs good airflow, so placement matters for performance and for neighbour comfort. We’ll recommend a spot that balances efficiency, access for servicing, and noise reduction. The sound is usually comparable to a quiet outdoor appliance, but it can be noticeable if installed too close to bedrooms or boundary fences. That’s why we plan external placement carefully, especially on Wellington’s tighter urban sections, so your system runs well and stays unobtrusive.
Can you replace my old electric cylinder with a heat pump hot water system?
Yes, replacing an older electric cylinder with a heat pump hot water cylinder upgrade is a common job for us in Wellington. We’ll assess your current setup, space, plumbing layout, and electrical supply, then recommend the most practical system. In many cases, the changeover is straightforward, but some homes need minor updates to wiring or placement. Once installed, most homeowners notice improved efficiency and lower running costs compared to older electric systems.
Can I switch from gas to an electric heat pump hot water heater?
Absolutely. Switching from gas to an electric heat pump hot water heater is becoming more popular in Wellington as households look for long-term savings and a simpler, all-electric home setup. We’ll check what needs to happen with your existing gas equipment and confirm what electrical capacity is available. Then we’ll install a correctly sized hot water heat pump and make sure everything is compliant and safe. It’s a great option if you’re planning other electrification upgrades in the future too.
Are heat pump water heaters for sale to buy directly through PlumbSpec?
PlumbSpec supplies and installs heat pump water heaters across Wellington. Because these systems must be installed by a licensed plumber, we don’t offer supply-only options. Instead, we manage the full process for you. That includes helping you choose the right model for your household, confirming correct sizing, and planning the installation properly. This ensures your heat pump hot water cylinder is compliant, set up correctly, and delivers reliable hot water year-round from day one.
