Aquatech Heat Pump Review: Is It the Right Hot Water System for Your Home?

Apr 15, 2023

The Aquatech heat pump is a hot water option for households comparing energy-efficient electric hot water systems. It is commonly considered by customers replacing an older electric storage tank, looking to reduce reliance on standard electric element heating, or wanting a heat pump that can suit everyday residential hot water use.

Like any heat pump hot water system, Aquatech should not be chosen on efficiency claims alone. The right choice depends on your household size, hot water demand, outdoor location, airflow, drainage, electrical setup, noise placement, warranty expectations, access and whether the unit is being ordered supply only or with a supplied-and-installed option where available.

This Aquatech heat pump review looks at where it can make sense, where buyers need to be careful, and when it may be worth comparing other heat pump options from brands such as iStore, Enviroheat, Rheem and Rinnai.

Quick answer: is an Aquatech heat pump worth considering?

An Aquatech heat pump can be worth considering if you want an electric hot water upgrade and your property has the right outdoor location, airflow, drainage and electrical setup.

It may suit:

Homes replacing an old electric storage tank
Households wanting a heat pump hot water system
Properties with suitable outdoor space
Homes with good airflow around the unit
Customers comparing electric hot water running costs
Homes where noise placement is acceptable
Customers with their own licensed installer arranged
Eligible Brisbane and Gold Coast customers where supplied-and-installed options are available

It may not suit every home. Heat pumps need more site planning than a basic like-for-like electric storage replacement.

What is an Aquatech heat pump?

An Aquatech heat pump is an electric hot water system that uses heat pump technology to heat stored water. Instead of relying only on a standard electric element, a heat pump draws heat from the surrounding air and transfers it into the water.

This makes it different from a standard electric storage hot water system.

A heat pump system still stores hot water in a tank, but it can use less electricity than a traditional electric storage unit in suitable conditions.

Aquatech heat pumps are commonly compared by customers wanting:

A more efficient electric hot water option
An alternative to standard electric storage
A heat pump for family hot water use
A system that may suit solar-powered homes
A replacement for an old electric tank
Supply-only ordering or installed options where available

Aquatech heat pump pros

Aquatech heat pumps can offer several advantages when the home and installation site suit the product.

Potential benefits include:

Heat pump technology for efficient electric hot water
Suitable for homes wanting to move away from standard electric storage
Useful where natural gas is not available
Can suit households with suitable outdoor space
May pair well with solar electricity where the setup and timer strategy suit
Can be compared for homes, rentals and renovation projects
Supply-only ordering available for customers with their own licensed installer arranged
Supplied-and-installed options may be available on selected products in eligible Brisbane and Gold Coast areas

The strongest use case is usually an electric storage replacement where the site is suitable for a heat pump.

Aquatech heat pump cons

Aquatech may not suit every property.

Potential drawbacks to consider include:

Needs suitable outdoor airflow
Needs condensate drainage
Needs enough physical access for delivery and installation
Needs acceptable noise placement
May need electrical work
Recovery time may differ from gas continuous flow or large electric storage systems
Performance can vary with climate, usage and settings
Installation quality matters
Warranty support depends on correct selection, installation and maintenance
It may not be the best fit for tight courtyards, enclosed spaces or noise-sensitive locations

Heat pump hot water should be chosen around the site, not just the product price or energy claims.

How an Aquatech heat pump works

An Aquatech heat pump uses electricity to run a compressor and fan system that extracts heat from the surrounding air. That heat is transferred into the stored water inside the tank.

In simple terms:

The fan draws in air
The heat pump extracts heat from that air
The system transfers heat into the water
Heated water is stored in the tank
The home uses stored hot water as needed
The system reheats based on its controls, settings and demand

This is why location matters. A heat pump needs access to surrounding air to work properly.

Aquatech vs standard electric hot water

Aquatech heat pumps are commonly compared against standard electric storage systems.

Feature	Aquatech heat pump	Standard electric storage
Main heating method	Heat pump technology	Electric element
Energy use	Lower in suitable conditions	Usually higher
Installation complexity	More site-specific	Often simpler like-for-like
Outdoor space	Usually important	Depends on model
Noise	Fan and compressor noise to consider	Usually quieter
Drainage	Condensate drainage needed	Standard discharge drainage
Upfront cost	Usually higher	Often lower
Best suited to	Efficiency-focused electric homes	Simple electric replacements

A heat pump may be the better long-term option where the site suits. A standard electric system may still be more practical where budget, access or location makes heat pump installation difficult.

Aquatech vs gas hot water

Aquatech heat pumps and gas hot water systems suit different properties.

A heat pump uses electricity. A gas hot water system uses natural gas or LPG.

A heat pump may suit:

Homes without gas
Homes with solar electricity
Customers wanting an efficient electric option
Properties with suitable outdoor space
Homes replacing an old electric storage tank

Gas hot water may suit:

Homes already set up for natural gas or LPG
Customers wanting continuous flow gas hot water
Properties with suitable gas pipe sizing
Homes where gas installation already exists
Customers needing compact wall-mounted options

Natural gas and LPG are not interchangeable. Any gas system must match the property’s gas type and be installed by a licensed gas fitter.

Aquatech vs other heat pump brands

Aquatech is one of several heat pump brands customers may compare.

Before choosing Aquatech, compare it against other brands and product categories such as:

Compare:

Tank size
Household suitability
Noise rating
Warranty terms
Dimensions
Recovery rate
Installation requirements
Electrical requirements
Outdoor clearance needs
Price
Supply-only vs installed options
Installer familiarity
Service and parts availability

The best heat pump is the one that suits the home and installation location.

Compare options in the Aquatech / Hydrotherm hot water systems collection.

Energy efficiency: what to know before buying

Heat pumps can reduce electricity use compared with standard electric storage systems in suitable conditions. However, real-world results depend on the home.

Efficiency depends on:

Climate
Outdoor air temperature
Installation location
Airflow
Tank size
Household hot water use
Timer settings
Solar electricity setup
Electricity tariff
Maintenance
Recovery demand
Backup element use where applicable

Avoid choosing a heat pump based only on a headline savings claim. The result depends on the property and how the system is used.

Does Aquatech work well in cold weather?

Heat pump performance can be affected by colder outdoor temperatures. This does not mean a heat pump cannot work in cooler conditions, but it does mean performance and recovery should be checked against the product specifications and household demand.

In colder locations or high-demand homes, ask:

What is the operating temperature range?
How does recovery change in colder weather?
Is backup heating used?
What is the expected hot water recovery time?
Does the tank size suit winter usage?
Is the installation location exposed or sheltered?
Will the household use most hot water in one peak period?

For Brisbane, Gold Coast and many warmer Australian regions, heat pump conditions may be more favourable than colder southern or inland locations, but site suitability still matters.

Hot water recovery time

A heat pump usually does not behave the same way as instant gas or a large standard storage system.

Recovery time depends on:

Tank size
Heat pump capacity
Outdoor air temperature
Usage pattern
Timer settings
Backup element settings
Household demand
Installation location
Whether multiple showers run back-to-back

If your household has heavy peak hot water use, do not choose based on tank size alone. Check recovery and usage pattern as well.

Noise considerations

Heat pumps have a fan and compressor, so noise placement matters.

Before choosing an Aquatech heat pump, check where the unit will sit in relation to:

Bedroom windows
Neighbouring homes
Courtyards
Unit complexes
Boundary fences
Outdoor living areas
Side access paths
Apartment balconies
Noise-sensitive spaces

Even if a heat pump is within acceptable noise limits, a poor location can make it annoying.

Airflow requirements

Heat pumps need airflow. They should not be installed in tight enclosed spaces where air cannot move properly.

Poor airflow can affect:

Efficiency
Recovery
Noise
System performance
Long-term reliability

Avoid locations such as:

Sealed cupboards
Tight service cavities
Enclosed garages without suitable ventilation
Under low decks with poor clearance
Tight side paths with blocked airflow
Small courtyards with limited ventilation

A licensed installer should confirm the location before ordering.

Condensate drainage

Heat pumps create condensate as part of normal operation. This needs to drain safely.

Before choosing an Aquatech heat pump, check:

Where condensate will drain
Whether drainage work is needed
Whether the location can stay dry and safe
Whether discharge will affect paths, slabs or neighbours
Whether additional plumbing is required

Poor drainage can create nuisance water, slippery surfaces or installation issues.

Electrical requirements

A heat pump is still an electric appliance. The electrical setup must suit the selected unit.

Check:

Existing circuit
Switchboard capacity
Electrical compliance
Timer or solar timing options
Manufacturer requirements
Whether electrical work is needed
Whether a licensed electrician is required
Whether the existing electric storage circuit is suitable

Supply-only customers should confirm electrical suitability before ordering.

Solar power compatibility

Heat pump hot water can be a good match for homes with rooftop solar when the setup is planned properly.

A solar-friendly setup may use daytime heating so the heat pump runs while solar power is available.

However, this depends on:

Solar system size
Timer settings
Household usage
Electricity tariff
Tank size
Recovery needs
Electrical setup
Installer advice

Do not assume every heat pump automatically uses solar power well. It needs the right control strategy.

Aquatech heat pump for small homes

An Aquatech heat pump may suit smaller homes where the tank size matches demand and the outdoor location is suitable.

It may suit:

Couples
Small families
Units with suitable outdoor installation space
Townhouses
Granny flats with suitable demand
Homes replacing electric storage

It may not suit a small property if the available installation location is too enclosed, too close to bedrooms, poorly drained or difficult to access.

Aquatech heat pump for family homes

For family homes, sizing and recovery are critical.

Check:

Number of people
Number of bathrooms
Shower length
Back-to-back showers
Bath use
Laundry use
Dishwasher use
Morning demand
Evening demand
Tank recovery
Solar timing if used

A family home should not choose a heat pump purely on the lowest price. It needs enough stored hot water and recovery for the way the household actually uses water.

Aquatech heat pump for rental properties

A heat pump can suit rental properties where it is correctly sized and simple for tenants to use.

For rentals, consider:

Tenant demand
Number of bedrooms
Number of bathrooms
Simple operation
Maintenance access
Noise placement
Reliability
Warranty documentation
Installer access
Cartridge or filter maintenance where relevant
Whether tenants understand boost settings if applicable

For rental properties, reliability and simple operation matter more than chasing the biggest theoretical saving.

Aquatech heat pump for Airbnb and short-stay properties

Short-stay properties need reliable hot water for maximum guest occupancy.

A heat pump may suit some Airbnb properties, but check:

Guest count
Number of bathrooms
Back-to-back showers
Laundry between bookings
Bath use
Peak demand
Recovery time
Noise placement
Boost settings
Maintenance access

Guest hot water complaints can be expensive, so do not undersize the system.

Aquatech heat pump for renovations

A renovation is a good time to plan the hot water system properly.

Before choosing an Aquatech heat pump for a renovation, confirm:

Final bathroom count
Fixture locations
Outdoor unit location
Drainage
Electrical supply
Solar timing
Access after renovation
Noise placement
Space around the unit
Future household demand

Do not leave heat pump location until the end of the renovation. It should be planned with plumbing and electrical layout.

Installation: what needs to be checked?

Aquatech heat pump installation should be assessed by a licensed professional.

Important checks include:

Existing system type
Existing tank size
Access
Outdoor location
Airflow
Drainage
Electrical supply
Base or slab condition
Pipework
Valves
Tempering valve requirements
Old unit removal
Disposal
Compliance upgrades
Manufacturer clearances
Noise placement

A poor installation location can reduce performance and create long-term problems.

Supply-only Aquatech heat pumps

Supply-only ordering can suit customers who already have their own licensed installer arranged.

Supply only may suit:

Builders
Renovators
Landlords
Property managers
Trade customers
Customers outside installed service areas
Customers managing their own installation

Supply-only product pricing generally does not include installation, valves, old unit removal, disposal, electrical work, plumbing changes, drainage work, base work, access upgrades or compliance upgrades unless clearly selected or included.

Before ordering supply only, your installer should confirm the Aquatech heat pump suits the home.

Supplied-and-installed Aquatech heat pumps

Anode checks where applicable
General system inspection
Manufacturer-recommended servicing

A heat pump that is never checked or maintained may not perform as expected over time.

Common mistake: choosing Aquatech based only on efficiency claims

Efficiency matters, but it is only one part of the decision.

Also check:

Household demand
Recovery time
Outdoor location
Noise placement
Drainage
Electrical requirements
Access
Maintenance
Warranty terms
Total replacement cost

A heat pump can be efficient and still be the wrong choice for the site.

Common mistake: ignoring airflow

A heat pump needs air movement. Installing it in a tight or enclosed space can reduce performance.

Before ordering, confirm airflow clearances with the installer.

Common mistake: ignoring drainage

Condensate drainage is not optional. Poor drainage can create nuisance water and installation issues.

Check the drain location before ordering.

Common mistake: assuming heat pumps are silent

Heat pumps are not silent. They make fan and compressor noise.

Choose a location that avoids bedrooms, neighbours and quiet outdoor spaces where possible.

Common mistake: undersizing the tank

An undersized heat pump may run out of hot water during peak demand.

If your household has long showers, multiple bathrooms or back-to-back use, check tank size and recovery carefully.

Common mistake: assuming it will suit every climate

Heat pump performance can vary with outdoor temperature.

In colder areas, check product specifications and installer advice before choosing.

Common mistake: comparing only product price

The product price is not the full replacement cost.

Extra costs may include:

Valves
Disposal
Old unit removal
Electrical work
Pipework changes
Drainage
Base work
Access issues
Compliance upgrades

Compare the total pathway, not only the product price.

Final verdict: should you buy an Aquatech heat pump?

An Aquatech heat pump can be a practical option for homes wanting an energy-efficient electric hot water upgrade, especially where the property has suitable outdoor space, airflow, drainage, access and electrical setup.

It is worth considering if you are replacing an older electric storage system and want to compare heat pump options. It may be less suitable if the site is enclosed, noise-sensitive, poorly drained, difficult to access, or if the household has very high peak hot water demand.

Before ordering, compare Aquatech against other heat pump and hot water brands, including iStore hot water systems, Enviroheat hot water systems, Rheem hot water systems and Rinnai hot water systems.

The best heat pump hot water system is not just the one with the lowest running cost claim. It is the one that suits your home, climate, installation location, hot water demand and long-term expectations.
