Rising power bills and gas costs are driving Wellington homes off traditional cylinders
Hot water is typically around a third of a New Zealand household's power bill, and many Wellington households are seeing gas costs rise sharply as daily line charges increase.
An old electric cylinder or gas system quietly drains money every quarter, and switching providers rarely changes the underlying running cost.
A hot water heat pump can significantly reduce your hot water running costs, helping many households save hundreds of dollars each year while providing reliable hot water every day.

Hot Water Heat Pumps - Overview:
Hot water heating across the Greater Wellington region using Daikin, Mitsubishi and Toshiba Carrier heat pump hot water cylinders, engineer-sized for each home.
- Split-system hot water heat pump options from Daikin and Mitsubishi AquaCore
- Toshiba Carrier monoblock cylinders with five years parts and labour cover
- Hot water heat pumps capable of reaching Legionella-safe temperatures without relying on electric boost heating
- Cylinder sizing by an in-house mechanical engineer during on-site consultation
- Gas-to-electric conversions including Mitsubishi Ecodan for radiator central heating
- Wi-Fi scheduling to run the heat pump water heater on daytime solar
Hot water heat pumps engineered to dramatically reduce running costs
- Hot water typically accounts for around one third of household electricity use
- Heat pump systems can dramatically reduce those running costs
- Sized for your home by an in-house mechanical engineer
Hot water heating installed across the Greater Wellington region, from Kapiti and Porirua to Hutt Valley, Levin and Masterton.
Why hot water heat pumps cost less to run
A standard electric hot water cylinder creates heat using an electric element. A hot water heat pump works differently, drawing warmth from the surrounding air and transferring it into the water. Because it moves heat rather than generating it directly, it uses far less electricity to produce the same amount of hot water.
That efficiency is measured using a Coefficient of Performance (COP). While a standard heat pump for home heating typically operates between 3.5 and 4.5, the Daikin COâ‚‚ hot water system achieves a COP of up to 6.15 and still performs at around 4.5 on a frosty Wellington morning.
Unlike many systems that rely on an electric element to reach Legionella-safe temperatures, the Daikin system heats water to 72°C using refrigerant alone. That keeps running costs low while still delivering reliable hot water throughout the year.

Choosing between split and monoblock systems
Two configurations are available; the right one depends on the property, existing setup and where the outdoor unit can sit.
- Split system: the outdoor compressor is separate from the cylinder, which stays indoors or moves outside. The Daikin unit runs at around 38 decibels and sits low, reducing neighbour noise. Cylinders are 250 and 315 litres, output around 6kW, warranty seven years.
Mitsubishi AquaCore, another split option, can sometimes bolt onto an existing solar-ready cylinder.
- Monoblock: the heat pump sits atop the outdoor cylinder as one unit. Toshiba Carrier is preferred, with five years parts and labour plus five years parts only.
Replacing gas hot water and pairing with solar
Wellington households are moving off gas as daily line charges climb from $0.50 to $2.50, as some households are seeing significantly higher gas bills. A gas-to-electric hot water conversion removes reticulated or bottled gas and cuts running costs.
If solar is installed or planned, Wi-Fi scheduling times the cylinder to heat using free generation, and bolt-on software lets a cylinder communicate with the solar system. Sister company Seven Electrical handles the solar side.

A heat pump water heater draws warmth from the surrounding air and transfers it into the cylinder using refrigerant and a compressor - similar to a fridge running in reverse.
Because it moves heat rather than generating it directly, a heat pump hot water system uses a fraction of the electricity of a standard element cylinder.
Yes. The Daikin CO₂ system holds a COP of around 4.5 at 0°C, so performance stays strong through frosty mornings and cold southerlies. Split systems place the compressor outside where it draws warmth from ambient air, while monoblock options integrate everything in one outdoor unit.
Both keep delivering hot water reliably through winter.
One Abode customer saw their monthly hot water bill drop from $90 to $20 after installation - around $1,000 a year. Actual savings depend on household size, water usage and the system being replaced, with older electric element cylinders and gas systems typically showing the largest reductions.
Cylinder sizing depends on occupant numbers, peak usage and appliance load. Daikin systems are available in 250 and 315 litre cylinders. Sizing is calculated during the on-site consultation by Abode's in-house mechanical engineer rather than estimated remotely, so the system matches real-world demand.
A well-maintained heat pump hot water system typically lasts 15 to 20 years, with the cylinder often outlasting the heat pump component. Annual servicing keeps performance consistent, protects the refrigerant circuit and maintains manufacturer warranty cover.
Daikin hot water heat pumps carry a seven-year manufacturer warranty as standard.
