Heat Pump Water Heaters Wellington
Heat Pump Hot Water Cylinders – Latest News – April 2026
Rinnai has a new heat pump water heaters that has a 10 Amp connection which means if you have a cable already run for water heater there is no need to upgrade the cable meaning the install costs are lower.
Eg you have a dedicated circuit for hot water heating to an external water heater or an internal water heat we can extend that cable to the new water heater instead of running a new cable.
We will update you as more info becomes available.
What Is a Heat Pump Hot Water Cylinder?
How Does a Heat Pump Water Heater Work?
A heat pump hot water cylinder works by extracting warmth from the surrounding air and transferring it into the water tank.
The process includes:
• A fan drawing in ambient air
• A refrigerant absorbing heat through a heat exchanger
• A compressor increasing the temperature of the refrigerant gas
• Heat transferring into the water stored in the cylinder
• Cooler air being expelled
Instead of creating heat, the system moves existing heat, which dramatically reduces electricity consumption.
Why Choose Heat Pump Hot Water?
Why Upgrade to a Heat Pump Hot Water System?
Benefits include:
• 2–3x more energy efficient than standard electric cylinders
• Lower power bills
• Reduced carbon footprint
• Reduced greenhouse gas emissions
• Ideal for eco-conscious homeowners
• Suitable for homes wanting to future-proof energy costs
By leveraging existing heat rather than generating it, these systems provide sustainable hot water with lower operating costs.

What are the top 10 benefits of using a Heat Pump Water Heater as opposed to Gas or Solar water heaters?
- Energy Efficiency: HPWHs are 2-3 times more energy-efficient than traditional electric or gas water heaters, reducing energy bills significantly.
- Lower Operating Costs: Their efficiency translates to lower utility costs, making them a cost-effective choice over the long term.
- Environmental Impact: HPWHs use less energy, which reduces greenhouse gas emissions and helps lower your carbon footprint.
- Renewable Energy Integration: They pair well with solar panels, allowing homeowners to maximize renewable energy use for heating water.
- Durability: Many HPWHs have longer lifespans (10-15 years or more) compared to conventional water heaters, offering better long-term value.
- Cooler Spaces: HPWHs expel cool, dehumidified air as a byproduct, making them ideal for locations like basements or garages in warm climates.
- Safety: Unlike gas water heaters, HPWHs don’t rely on combustion, eliminating the risk of carbon monoxide leaks.
- Quiet Operation: Modern HPWHs are designed to operate quietly, ensuring minimal disruption in living spaces.
- Smart Features: Many models come equipped with Wi-Fi or programmable settings, allowing you to optimize energy use and customize water heating schedules.
- Consistent Hot Water Supply: HPWHs are designed to provide a steady and reliable supply of hot water, even in households with high demand, thanks to their efficient heat transfer systems and larger tank sizes often available.
How do Heat Pump water heaters compare to Gas water heaters?
Heat pump water heaters (HPWHs) and gas continuous flow (tankless) water heaters offer distinct advantages, making them suitable for different needs. HPWHs are highly energy-efficient, using electricity to transfer heat from the air to heat water, which can result in lower utility bills and reduced environmental impact. In contrast, gas continuous flow water heaters provide an unlimited supply of hot water on demand, making them ideal for households with high or variable water usage.
However, HPWHs excel in long-term energy savings and sustainability, while gas heaters rely on fossil fuels, leading to higher carbon emissions. Gas units may have a lower upfront cost and don’t require as much space, but HPWHs can often save more money over time due to their efficiency. The choice depends on your priorities: cost, environmental impact, or demand for instant, unlimited hot water.
