Best Heat Pump Hot Water Systems in 2024: Top Picks for Brisbane & Gold Coast Homes

Nov 15, 2022

Heat pump hot water systems have become one of the most popular upgrades for Australian homes looking to move away from older electric storage systems. They use heat from the surrounding air to help heat the water, which can reduce electricity use compared with standard electric hot water when the system is selected and installed correctly.

For Brisbane, the Gold Coast and South East Queensland, heat pumps are especially worth considering because the warmer climate generally suits heat pump operation. They can be a strong option for homes with rooftop solar, families using a lot of hot water, or homeowners wanting a more efficient replacement without needing gas or roof-mounted solar collectors.

The best heat pump hot water system in 2024 is not always the cheapest model, the biggest tank, or the one with the highest advertised efficiency. The right choice depends on household size, installation location, noise, recovery time, solar PV setup, budget, warranty support and long-term reliability.

JR Gas & Water can help compare heat pump hot water systems, budget heat pump systems, quiet heat pump systems, large family heat pumps and plug-in replacement heat pumps based on your home, not just the product name.

Quick answer

The best heat pump hot water systems in 2024 include the iStore 270L, Rheem Ambiheat 270L, Stiebel Eltron WWK302, Enviroheat 250L, Rinnai Enviroflo and Reclaim Energy CO2 systems.

For many Brisbane and Gold Coast family homes, a 250L to 300L heat pump is the most common size range to compare. Smaller households may suit a 200L to 250L system, while larger families or high-use homes may need 300L or more.

If you want a balanced family system, the iStore 270L and Rheem Ambiheat 270L are strong options to compare. If quiet operation and premium build quality matter, Stiebel Eltron and Reclaim are worth looking at. If upfront price is a major factor, Enviroheat and Rinnai Enviroflo may suit some homes better.

How we judged the best heat pump hot water systems

A good heat pump should be judged on more than the advertised energy savings.

The main factors to compare are:

  • Tank capacity

  • Household suitability

  • Recovery performance

  • Noise level

  • Brand support

  • Warranty support

  • Installation practicality

  • Solar PV compatibility

  • Smart controls and timers

  • Parts availability

  • Long-term ownership value

  • Suitability for Brisbane and Gold Coast conditions

A cheap heat pump can be a good option in the right home. A premium heat pump can also be worth the extra cost if the location, usage and long-term ownership plans justify it.

Best overall family option: iStore 270L Heat Pump

The iStore 270L is one of the most popular heat pump options for Australian families, especially homes with rooftop solar.

Best suited to

  • Medium to larger households

  • Homes with solar PV

  • Replacing older electric storage systems

  • Families wanting a strong all-round heat pump

  • Homeowners wanting good capacity without moving into the highest price tier

Why it stands out

The iStore 270L is a practical family-sized heat pump with a strong focus on energy efficiency and solar-friendly operation. For homes with rooftop solar, the system can often be timed to heat during the day when solar generation is strongest, depending on the setup and household usage.

It is a good option for homeowners wanting a balance between capacity, efficiency and installed value.

Things to consider

Solar compatibility depends on more than the heat pump itself. Timer settings, tariff setup, solar generation, household usage and installation location all affect the result.

Best mainstream brand option: Rheem Ambiheat 270L

The Rheem Ambiheat 270L is a strong choice for homeowners who want a recognised hot water brand, practical family capacity and broad support.

Best suited to

  • Family homes

  • Replacing older electric storage hot water

  • Customers who prefer a major hot water brand

  • Homes needing a 270L heat pump

  • Brisbane and Gold Coast homes with suitable outdoor space

Why it stands out

Rheem is one of the best-known hot water brands in Australia, and the Ambiheat range gives homeowners a heat pump option backed by a familiar name.

The 270L size is a practical match for many family homes, especially where the current electric storage system is expensive to run or due for replacement.

Things to consider

The Rheem Ambiheat is not always the lowest upfront option. It is better suited to homeowners who value brand familiarity, installer support and a mainstream system rather than simply chasing the cheapest heat pump.

Best premium quiet option: Stiebel Eltron WWK302

The Stiebel Eltron WWK302 is a premium heat pump option for homeowners who want strong build quality, quiet operation and a respected heat pump brand.

Best suited to

  • Larger households

  • Homes where noise matters

  • Premium replacements

  • Energy-conscious homeowners

  • Properties where the heat pump may sit near bedrooms, windows or neighbouring homes

Why it stands out

Stiebel Eltron systems are often compared by customers who want a higher-quality heat pump rather than a budget model. The WWK302 is a good option where quiet operation, long-term quality and brand reputation matter.

It can be a strong fit for Brisbane and Gold Coast homes where the system needs to be installed near living areas or boundaries and noise needs to be considered carefully.

Things to consider

Premium systems usually cost more upfront. For some households, that extra cost makes sense. For others, a mid-range or budget system may be enough.

Best budget-friendly option: Enviroheat 250L

The Enviroheat 250L is a practical entry-level heat pump for homeowners wanting to move away from standard electric storage without paying premium heat pump prices.

Best suited to

  • Budget-conscious homeowners

  • Investment properties

  • Smaller to average family homes

  • Replacing older electric storage systems

  • Homes with suitable outdoor installation space

Why it stands out

The Enviroheat 250L offers a lower-cost pathway into heat pump hot water. It can be a sensible option for customers who want better efficiency than standard electric storage but do not need a premium system.

For many homes, a 250L tank can suit smaller families or moderate hot water demand.

Things to consider

Budget heat pumps should be selected with realistic expectations. Noise, support, warranty, recovery time and long-term reliability should still be considered before choosing purely on price.

Best compact value option: Rinnai Enviroflo

The Rinnai Enviroflo is worth comparing for homeowners who want a known hot water brand and a practical heat pump option for standard residential use.

Best suited to

  • Smaller to medium households

  • Homes replacing electric storage

  • Customers wanting a known brand

  • Properties with suitable outdoor space

  • Homes where a compact heat pump package is preferred

Why it stands out

Rinnai is already a familiar name in gas hot water, and the Enviroflo range gives homeowners another heat pump option to compare against brands such as iStore, Rheem, Enviroheat and Stiebel Eltron.

It can suit homeowners looking for a practical replacement where the installation location and household demand are a good match.

Things to consider

As with any heat pump, the model should be matched to the home’s actual hot water demand. Tank size, recovery time, airflow, drainage and noise placement should all be checked.

Best premium sustainability option: Reclaim Energy CO2 Heat Pump

The Reclaim Energy CO2 heat pump range is a premium option for homeowners who want high-end efficiency, low-noise operation and a stronger sustainability focus.

Best suited to

  • Larger households

  • Premium homes

  • Customers wanting a CO2 refrigerant system

  • Solar PV homes

  • Homes where noise is a major consideration

  • Long-term homeowners wanting a higher-end system

Why it stands out

Reclaim is often compared by homeowners who want one of the more premium heat pump options on the market. It is a strong choice for customers who are focused on long-term performance, quiet operation and higher-end technology rather than lowest upfront cost.

Things to consider

Reclaim systems sit at the premium end of the market. They may not suit every budget, especially where the home is a short-term hold, rental property or basic like-for-like replacement.

Quick comparison table

Heat pump system Best suited to Main advantage
iStore 270L Families with solar PV Strong all-round family value
Rheem Ambiheat 270L Mainstream family homes Known brand and practical capacity
Stiebel Eltron WWK302 Premium homes and quiet installs Build quality and quieter operation
Enviroheat 250L Budget-conscious replacements Lower-cost heat pump option
Rinnai Enviroflo Compact residential replacements Known brand and practical value
Reclaim Energy CO2 Premium efficiency-focused homes High-end performance and sustainability focus

What size heat pump hot water system do you need?

The right size depends on household use, not just the number of people living in the home.

Household size Common heat pump size range Notes
1–2 people 150L–220L May suit units, couples or low-use homes
3–4 people 250L–280L Common range for many family homes
5+ people 270L–340L+ Consider larger tanks and stronger recovery
High-demand homes 300L–400L+ Best assessed from bathrooms, shower habits and peak use

A family of four with short showers may need a different system from a family of four with teenagers, long showers and heavy evening hot water use.

Heat pump vs electric storage hot water

Many heat pump customers are replacing an older electric storage system.

Feature Heat pump hot water Electric storage hot water
Energy use Lower electricity use when suitable Higher direct electric element use
Upfront cost Usually higher Usually lower
Installation Needs airflow, drainage and location planning Often simpler replacement
Solar PV compatibility Often good with timer control Depends on tariff and setup
Noise Fan and compressor noise must be considered Generally quiet
Best suited to Long-term efficiency Simple low-complexity replacement

If lowest upfront cost is the main priority, electric hot water systems may still be worth comparing. If the goal is reducing electricity use over time, heat pumps are usually the stronger category.

Heat pump vs solar hot water

Heat pumps and solar hot water systems both help reduce reliance on standard electric heating, but they suit different homes.

Feature Heat pump hot water Solar hot water
Main requirement Suitable outdoor location and airflow Suitable roof space and sun exposure
Roof panels Not required Required
Shaded roofs Often more practical Can be a problem
Solar PV homes Often a good match May compete for roof space
Installation Ground-level tank location Roof collectors and tank/pipework setup
Best suited to Homes wanting efficient electric hot water Homes with ideal solar collector conditions

If the roof is shaded, full of solar panels or difficult to access, a heat pump may be more practical than solar hot water systems.

Heat pump vs instant gas hot water

Heat pumps and instant gas hot water systems solve hot water demand in very different ways.

Feature Heat pump hot water Instant gas hot water
Energy source Electricity Natural gas or LPG
System type Storage tank with heat pump recovery Continuous flow on demand
Space required Tank location required Compact wall-mounted unit
Best suited to Efficient electric replacement Homes with suitable gas supply
Key consideration Airflow, drainage and noise Gas pipe sizing and gas supply

If your home already has natural gas and limited space, instant gas hot water systems may still make sense. If your home has solar PV and you want an efficient electric option, a heat pump may be the better comparison.

Why solar PV matters with heat pumps

A heat pump can work well with rooftop solar because it can often be timed to run during the day when solar generation is strongest.

This can help when:

  • The home exports excess solar during daylight hours

  • The heat pump has timer or smart-control settings

  • Hot water use is predictable

  • The tank is large enough for the household

  • The system can recover before evening use

  • The installation is matched to the home

Solar PV does not automatically make every heat pump cheap to run. The system still needs to be correctly sized, scheduled and installed.

Brisbane and Gold Coast installation considerations

Heat pumps can perform well in South East Queensland, but the installation location matters.

Common local considerations include:

  • Outdoor airflow around the heat pump

  • Distance from bedrooms and neighbours

  • Drainage for condensate and valve discharge

  • Narrow side access

  • Fence and wall reflection increasing noise

  • Coastal corrosion exposure on the Gold Coast

  • Homes with solar PV

  • Older electric systems on off-peak tariffs

  • Townhouse and body corporate requirements

  • Whether the unit can fit where the old tank was

  • Whether the switchboard or circuit needs work

  • Access for delivery and future servicing

A heat pump should not be installed in a poor location just because the old electric tank was there. Airflow, clearances, drainage and noise all matter.

Cost factors

The final installed cost of a heat pump hot water system can vary depending on:

  • Brand and model

  • Tank capacity

  • Existing system type

  • Installation location

  • Access to the site

  • Pipework changes

  • Electrical requirements

  • Drainage requirements

  • Base or slab requirements

  • Tempering valve and valve upgrades

  • Removal of the old system where included

  • Rebate or STC eligibility at the time of quoting

  • Brisbane, Gold Coast or wider SEQ location

Rebates, STCs and incentives can change, so they should always be checked at the time of quoting.

What can go wrong if you choose the wrong heat pump?

Choosing the wrong heat pump can lead to:

  • Not enough hot water

  • Slow recovery at peak times

  • Noise complaints

  • Poor airflow and reduced performance

  • Drainage issues

  • Higher-than-expected running costs

  • Overspending on features you do not need

  • Buying a cheap system with weak long-term support

  • Choosing a tank that is too small

  • Installing the system too close to bedrooms or neighbours

  • Poor solar PV scheduling

The best heat pump is the one that suits the actual home, not just the one with the best-looking spec sheet.

What to check before ordering a heat pump

Before choosing a heat pump, check:

  • Current hot water system type

  • Current tank size

  • Number of people in the home

  • Number of bathrooms

  • Whether hot water currently runs out

  • Whether the home has solar PV

  • Whether the current system is on off-peak power

  • Available outdoor installation space

  • Distance to bedrooms and neighbours

  • Drainage options

  • Site access

  • Whether you want budget, mid-range or premium quality

  • Whether quiet operation is important

  • Whether a plug-in replacement option is suitable

Photos of the existing hot water system, model plate, surrounding area, access path and switchboard can help narrow down the best recommendation.

Is a heat pump hot water system worth it in Brisbane?

Yes, a heat pump can be worth it in Brisbane when replacing an older electric storage system, especially where there is suitable outdoor space, good airflow and regular hot water demand.

Is a heat pump hot water system worth it on the Gold Coast?

Yes, heat pumps can suit many Gold Coast homes, but coastal exposure, noise placement, airflow and drainage should be considered before choosing a model.

What size heat pump do I need for a family of four?

Many families of four compare 250L to 280L heat pumps. If the household has long showers, teenagers, multiple bathrooms or heavy evening use, a larger or faster-recovery system may be worth considering.

Are heat pumps noisy?

Heat pumps use a fan and compressor, so they do make some noise. The noise level depends on the model and the installation location. If the unit will be near bedrooms, windows, fences or neighbours, compare quiet heat pump options carefully.

Can a heat pump work with solar panels?

Yes. Many homes use rooftop solar to help power a heat pump during the day. Timer settings, smart controls, solar production and household usage all affect how well this works.

Is a cheap heat pump a bad idea?

Not always. A budget heat pump can be suitable for some homes, rentals or lower-cost replacements. Premium systems may offer stronger build quality, quieter operation and better long-term support.

Should I choose a heat pump or instant gas hot water?

Choose a heat pump if you want efficient electric hot water and have a suitable outdoor location. Choose instant gas if the home has a suitable natural gas or LPG supply and you want compact continuous flow hot water.

Need help choosing the best heat pump hot water system?

If your current hot water system is leaking, expensive to run, undersized or due for replacement, JR Gas & Water can help compare suitable heat pump options for your home.

Browse heat pump hot water systems, compare large family heat pumps, or look at quiet heat pump systems if noise and placement matter.
