Why Switch to Heat Pump Hot Water?

It’s like a fridge, but in reverse. While a standard electric cylinder uses a heating element (like a giant kettle), a heat pump pulls heat from the surrounding air and transfers it into your water. It is the "Smartest" upgrade you can make for your property’s energy efficiency.

Massive Savings: Uses roughly 1kW of energy to create 3kW to 4kW of heat.
Eco-Friendly: Significantly reduces your carbon footprint compared to standard electric or gas.
Mains Pressure: Enjoy powerful, consistent showers throughout the entire house.
Future-Proof: Designed to meet and exceed New Zealand’s increasing energy efficiency standards.

Our Heat Pump Solutions

Standard electric cylinders are essentially giant kettles that is less efficient. By transitioning to a heat pump system, you’re installing a high-tech energy harvester that delivers mains-pressure luxury while slashing your monthly hot water bills by up to 70%.

Full System Upgrades

Replace your old, inefficient cylinder with a modern all-in-one unit. We specialise in removing aging low-pressure copper cylinders and installing high-efficiency heat pump water heaters. These units sit either outside or in your existing cylinder cupboard, providing mains pressure hot water for the whole family.

Retrofit Solutions

Connect a heat pump unit to your existing compatible cylinder. If you already have a modern, stainless steel mains-pressure cylinder, we can often retrofit a heat pump unit to it. This allows you to gain the efficiency of a heat pump without the cost of a full cylinder replacement.

Commercial Heat Pumps

High-volume hot water for Wellington businesses and apartments. From gyms to multi-unit residential blocks, we design and install large-scale heat pump arrays. These systems provide massive operational cost savings for high-use commercial environments.

Lower Running Costs Without Sacrificing Hot Water Performance

Modern heat pump hot water systems are designed to give Wellington households reliable hot water while using far less electricity than many traditional electric cylinders. Instead of generating heat directly, they draw warmth from the surrounding air and use it to heat your water more efficiently.

For many homes, this can mean a noticeable reduction in hot water running costs, especially if your current cylinder is older, inefficient, or struggling to keep up with daily demand.

Heat pump hot water can help with:

Lower electricity use: Heat pump systems are designed to use significantly less power than standard electric water heating.
Reliable daily supply: Correct sizing helps ensure your household has enough hot water for showers, washing, cleaning, and everyday use.
Better use of outdoor space: Many systems can be installed outside, helping free up valuable indoor cupboard or cylinder space.
A more future-ready home: A modern heat pump hot water system can improve efficiency, reduce reliance on older technology, and support a more energy-conscious household.

The key is choosing the right unit, placing it correctly, and installing it properly. We assess your current setup, household usage, available space, and plumbing requirements before recommending the best option.

Is a Heat Pump Hot Water System Right for Your Home?

A heat pump hot water system can be a smart upgrade for many Wellington homes, but the right choice depends on your property, household size, current cylinder, available space, and daily hot water use.

We assess your setup before recommending a system, so you know whether a full replacement or retrofit solution makes better sense.

A heat pump hot water system may suit your home if:

Your existing cylinder is old, inefficient, or expensive to run
Your household uses a lot of hot water
You want to free up indoor cylinder space
You are renovating or upgrading your home
You want lower running costs without unreliable hot water

The right system should be efficient, practical, correctly sized, and installed properly for long-term performance.

What our customers say

Frequently Asked Questions

Are hot water heat pumps cheaper to run than electric hot water cylinders?

Yes. Hot water heat pumps are usually cheaper to run than standard electric hot water cylinders because they use heat from the surrounding air to warm the water, rather than relying only on direct electric heating. Maxey Plumbing installs quality systems, including Rheem hot water heat pumps, to help Wellington homeowners reduce energy use while keeping a reliable hot water supply.

What is the best hot water heat pump brand for New Zealand homes?

Rheem is one of the most trusted hot water brands for New Zealand homes. Rheem hot water heat pumps are compact, efficient, and supported by strong local service networks. Maxey Plumbing recommends Rheem for many Wellington homes because their systems are well suited to residential use, reliable performance, and ongoing maintenance. We also install a variety of other brands of heat pump hot water cylinders depending on what best suits the installation.

Can a hot water heat pump replace my existing electric cylinder?

Yes. In many homes, a hot water heat pump can replace an older electric cylinder. The best option depends on your current cylinder, available space, household hot water demand, pipework, drainage, and electrical setup. Maxey Plumbing can assess your existing system and recommend whether a Rheem heat pump hot water system or another suitable solution is the right fit.

Where should a hot water heat pump be installed?

A hot water heat pump is usually installed outside or in a well ventilated area where it has good airflow, safe access, and suitable drainage. Placement matters because poor airflow or awkward positioning can reduce performance and make servicing harder. Maxey Plumbing checks the property layout before installation to make sure the system is positioned correctly.

Do hot water heat pumps work well in Wellington?

The system needs to be correctly sized for the household and installed in a suitable location with adequate airflow and drainage.
