Ultra-Efficient, Low-Carbon Hot Water Built for Wellington Homes

As Wellington homeowners look for smarter, more energy-efficient ways to heat their water, Daikin CO₂ hot water systems are quickly becoming one of the most advanced and future-proof solutions available in New Zealand.

Designed to perform exceptionally well in cooler climates like Wellington, Daikin’s CO₂ (carbon dioxide) heat pump water heaters deliver lower running costs, outstanding efficiency, and significantly reduced emissions—all while providing reliable hot water for modern households.

What Is a Daikin CO₂ Hot Water System?

A Daikin CO₂ hot water system is a heat pump water heater that uses R744 (natural CO₂ refrigerant) instead of conventional synthetic refrigerants.

Rather than heating water directly like a traditional electric cylinder or gas system, it:

• Extracts heat from the outdoor air

• Amplifies that energy through heat-pump technology

• Transfers it into your hot water cylinder

This proven technology is widely used overseas and is now gaining strong momentum in New Zealand as energy prices rise and sustainability becomes a priority.

Why Daikin CO₂ Hot Water Is Ideal for Wellington Homes

Wellington’s climate—cool winters, strong winds, and moderate humidity—is particularly well suited to CO₂ heat pump technology.

Key benefits for Wellington households include:

• Excellent efficiency even in cold outdoor temperatures

• Lower electricity consumption compared to standard electric cylinders

• Reduced carbon footprint using natural CO₂ refrigerant

• Quiet operation, ideal for suburban and high-density housing

• Future-proof refrigerant with a Global Warming Potential (GWP) of just 1

How Efficient Is a Daikin CO₂ Hot Water System?

Daikin CO₂ systems can produce up to four times more heat energy than the electricity they consume.

Compared with common alternatives:

• Electric hot water cylinders – Simple but expensive to run

• Gas hot water systems – Increasing gas costs and higher emissions

• Solar hot water – Weather-dependent and often higher upfront complexity

For many Wellington homeowners, CO₂ heat pump hot water provides the best balance of efficiency, reliability, and long-term savings.

Designed for Modern, Energy-Conscious Homes

Daikin CO₂ hot water systems are well suited to:

• New builds and architectural homes

• Renovations replacing electric or gas cylinders

• Homes with solar PV systems

• Families looking to improve energy efficiency and sustainability

Multiple cylinder sizes are available, allowing systems to be matched to small households through to large families with high hot water demand.

Lower Emissions, Higher Sustainability

Because these systems use natural CO₂ refrigerant, they:

• Avoid harmful synthetic refrigerants

• Have minimal environmental impact

• Align with New Zealand’s long-term climate and emissions goals

If reducing your household’s carbon footprint is important, Daikin CO₂ hot water is one of the cleanest hot water solutions currently available.

Daikin CO₂ vs Standard Heat Pump Hot Water

While standard heat pump hot water systems are already efficient, CO₂ systems offer additional advantages:

• Higher hot water temperatures

• Better performance in colder climates

• Longer-term refrigerant compliance

• Greater overall efficiency and system longevity

This makes them especially attractive in Wellington and the wider lower North Island.

Professional Installation Makes the Difference

To achieve maximum efficiency and reliability, correct system design and installation are critical. Considerations include:

• Household size and hot water usage

• Cylinder sizing

• Outdoor unit placement

• Electrical capacity and setup

A professional installation ensures optimal performance, quiet operation, warranty compliance, and long-term reliability.
