Best Envirosun Heat Pump Hot Water Systems: Complete Buyer’s Guide

Jun 21, 2026

Envirosun is commonly compared by Australian homeowners looking at heat pump hot water, efficient electric hot water and replacement options for older electric storage systems. The best Envirosun heat pump hot water system depends on your household size, tank capacity, outdoor location, airflow, condensate drainage, noise placement, electrical requirements, budget and whether the selected model suits your property.

At Hot Water Outlet, you can compare Envirosun hot water systems, heat pump hot water systems, electric hot water systems, hot water systems and common valves, pipework and fittings.

Quick Answer: Which Envirosun Heat Pump Hot Water System Is Best?

The best Envirosun heat pump hot water system is the model that suits your household’s hot water demand, outdoor space, airflow, drainage, electrical setup and tank capacity needs.

As a general guide:

Choose an Envirosun heat pump if you want efficient electric hot water and your property has suitable outdoor space.
Compare tank capacity before choosing a model.
Check whether your current hot water system keeps up with demand.
Make sure the proposed location has suitable airflow.
Consider noise placement near bedrooms, neighbours, courtyards and boundaries.
Confirm condensate drainage before ordering.
Check electrical requirements with a licensed electrician.
Confirm required valves, fittings and accessories before buying supply-only.

Envirosun may suit homes replacing electric storage where heat pump location requirements can be met. It is not automatically the right option for every property, especially where airflow, drainage, access or noise placement is difficult.

Envirosun Heat Pump Hot Water at a Glance

Buying Factor	What to Check
System type	Heat pump hot water
Energy source	Electricity
Main sizing method	Tank capacity in litres

Envirosun should be compared as part of the broader heat pump hot water systems category, not only as a brand decision.

Is Envirosun Heat Pump Hot Water Right for Your Home?

An Envirosun heat pump may suit your home if:

You are replacing an older electric storage system
You want efficient electric hot water
Natural gas or LPG is not available or not preferred
Outdoor space is available
Airflow around the unit is suitable
Condensate drainage can be managed
Noise placement is acceptable
The selected tank capacity suits household demand
Electrical requirements can be confirmed
Delivery access is suitable

An Envirosun heat pump may not suit if:

The only available location is enclosed
Airflow is restricted
The unit would be too close to bedrooms or neighbours
Drainage is difficult
Electrical upgrades are not practical
The selected tank is too small
A standard electric storage system is more suitable
A gas or instant gas system better matches the property

Heat pump hot water is a site suitability decision as much as a product decision. The system needs to match the household and the location.

Envirosun vs Standard Electric Hot Water

Many buyers compare Envirosun heat pump hot water against standard electric storage.

A standard electric hot water system may suit if:

You want a simple like-for-like replacement
The current electric tank location works
Outdoor airflow is limited
Noise placement is difficult
Condensate drainage is not practical
Upfront product cost is a major factor

An Envirosun heat pump may suit if:

Outdoor space is available
Airflow around the unit is suitable
Drainage can be managed
Electrical requirements can be confirmed
Efficient electric hot water is preferred
Tank capacity suits household demand

A heat pump can be a good option for the right home, but it should not be chosen automatically just because the old system was electric.

Envirosun vs Gas Hot Water

Envirosun heat pump hot water and gas hot water suit different properties.

An Envirosun heat pump may suit if:

The home does not have gas
You want an electric hot water option
Outdoor airflow is suitable
Tank capacity suits household demand
Electrical requirements can be met

A gas hot water system or instant gas hot water system may suit if:

Natural gas or LPG is available
Gas hot water is already installed
Continuous flow hot water is preferred
Gas supply and water pressure are suitable
A licensed gas fitter confirms the setup

Natural gas and LPG are not interchangeable, so gas buyers must confirm the correct gas type before ordering.

Best Envirosun Heat Pump for Replacing Electric Storage

Envirosun is often considered when replacing old electric storage hot water.

Before replacing electric storage with an Envirosun heat pump, check:

Current tank capacity
Whether the current system runs out
Number of people in the home
Number of bathrooms
Existing system location
New outdoor location
Airflow around the proposed position
Noise placement
Condensate drainage
Electrical requirements
Product dimensions
Delivery access

Do not assume the same tank size will suit if the current system regularly runs out. The replacement should be sized for real household demand.

Best Envirosun Heat Pump for One Bathroom

A one-bathroom home may suit an Envirosun heat pump if the household demand and outdoor location are suitable.

Check:

Number of occupants
Shower habits
Bath use
Kitchen hot water use
Laundry hot water use
Current tank capacity
Whether the current system keeps up
Outdoor airflow
Noise placement
Electrical requirements

A one-bathroom home with one or two people may have lower demand. A one-bathroom family home may need more stored capacity than expected.

Best Envirosun Heat Pump for Two Bathrooms

Two-bathroom homes need more careful heat pump sizing because demand can overlap.

Before choosing an Envirosun heat pump for a two-bathroom home, check:

Number of people in the home
Whether two showers may run close together
Bath use
Morning and evening peak demand
Current tank size
Whether the current system runs out
Desired tank capacity
Recovery needs
Outdoor location
Electrical requirements

For two bathrooms, do not choose only by upfront product price. Tank capacity and suitability matter more.

Best Envirosun Heat Pump for Families

Families often have higher hot water demand, especially during school mornings, evening showers and back-to-back use.

An Envirosun heat pump may suit a family if:

The selected tank capacity suits daily demand
Outdoor space is available
Airflow is suitable
Noise placement is acceptable
Condensate drainage can be managed
Electrical requirements are confirmed
The system location allows practical access
The household wants efficient electric hot water

Families should avoid undersizing. A heat pump that is too small can still run out of hot water, even if the brand and technology are suitable.

Best Envirosun Heat Pump for Small Homes

Small homes may suit Envirosun heat pump hot water if outdoor space is available and the household demand is moderate.

An Envirosun system may suit a small home if:

The household has low to moderate hot water use
The selected tank capacity matches demand
Outdoor location is practical
Airflow is not restricted
Noise placement works
Drainage can be managed
Delivery access is suitable

Small homes still need proper checking. A compact property may not always have a suitable heat pump location.

Best Envirosun Heat Pump for Units

Units can be more complicated because of space, airflow, noise and building rules.

An Envirosun heat pump may suit a unit if:

A suitable outdoor location is available
Body corporate rules allow the system
Airflow is not restricted
Noise will not affect neighbours
Condensate drainage can be managed
Product dimensions suit the space
Electrical requirements can be met
Delivery access is practical

An Envirosun heat pump may not suit some units if the only available location is enclosed, too close to bedrooms or too close to neighbouring properties.

For units, check building and body corporate requirements before ordering supply-only.

Best Envirosun Heat Pump for Townhouses

Townhouses can suit heat pump hot water, but location is important.

Before choosing Envirosun for a townhouse, check:

Side access
Courtyard space
Distance from bedrooms
Distance from neighbouring bedrooms
Boundary fence position
Outdoor airflow
Drainage options
Product dimensions
Body corporate or complex rules
Electrical requirements

A townhouse with good side access and airflow may suit heat pump hot water. A narrow enclosed side passage may not.

Best Envirosun Heat Pump for Rental Properties

Rental properties need hot water systems that suit likely tenant demand and reduce the risk of hot water complaints.

An Envirosun heat pump may suit a rental if:

The property has suitable outdoor space
Noise is unlikely to create issues
Tank capacity suits the number of bedrooms and bathrooms
Electrical requirements can be met
Drainage is practical
Access for maintenance is reasonable
Licensed tradespeople confirm suitability

Landlords should avoid choosing the smallest tank purely to reduce product price. Tenant demand may be higher than expected.

Best Envirosun Heat Pump for Renovations

Renovations are a good time to plan heat pump hot water properly because the final layout may be different from the current home.

Consider Envirosun during a renovation if:

You are replacing old electric storage
Outdoor space can be planned early
Drainage can be allowed for
Noise placement can be considered before landscaping
A second bathroom is being added
Electrical requirements can be checked
Solar or tariff setup is being reviewed
The finished home will have higher hot water demand

Plan for the finished household, not the old hot water system.

Envirosun Heat Pump for Solar Homes

Some buyers compare Envirosun heat pump hot water because they have rooftop solar or want to use more electricity during the day.

An Envirosun heat pump may suit a solar home if:

The product and setup suit the household
Electrical requirements can be confirmed
Timer or tariff considerations are checked
The unit can be located outdoors with suitable airflow
Tank capacity suits the household
Licensed tradespeople confirm the setup

Do not assume solar automatically makes any heat pump the best choice. The system still needs to suit the home’s usage, location and electrical setup.

Envirosun Tank Capacity: What Size Do You Need?

Heat pump hot water systems are storage systems, so tank capacity still matters.

Before choosing an Envirosun model, check:

Number of people in the home
Number of bathrooms
Shower duration
Back-to-back showers
Bath use
Kitchen hot water use
Laundry use
Current tank capacity
Whether the current system keeps up
Future household changes

A well-sized Envirosun heat pump can suit the home better than a smaller model chosen only for upfront price.

Outdoor Location and Airflow

Heat pump hot water systems need suitable outdoor airflow.

Before ordering Envirosun, check:

Whether the unit will be outdoors
Clearance around the system
Air movement around the location
Whether the area is enclosed
Distance from walls and fences
Distance from bedrooms
Distance from neighbours
Access for licensed tradespeople
Product dimensions
Manufacturer location requirements

Do not assume the existing electric storage location will automatically suit a heat pump.

Noise Placement

Heat pump hot water systems make operating noise, so placement should be checked carefully.

Consider whether the proposed location is near:

Bedroom windows
Neighbouring bedrooms
Courtyards
Outdoor living areas
Narrow side passages
Boundary fences
Unit balconies
Shared walls

The best location balances airflow, drainage, access and noise.

Condensate Drainage

Heat pump hot water systems can produce condensate during operation.

Before choosing Envirosun, check:

Where condensate will drain
Whether water may pool around the unit
Whether drainage work may be required
Whether the site has suitable fall
Whether drainage could create a slip risk
Whether the installer has confirmed requirements

Condensate drainage should be considered before ordering supply-only.

Electrical Requirements

Envirosun heat pump hot water systems use electricity and must be connected safely by licensed tradespeople.

Before ordering, check:

Existing electrical supply
Circuit requirements
Switchboard suitability
Timer or tariff setup where relevant
Product electrical specifications
Whether upgrades may be needed
Access for electricians
Compliance requirements

Hot Water Outlet sells supply-only products online. Electrical work is not included unless clearly stated and must be handled by appropriately licensed tradespeople.

Rebates and Incentives

Heat pump hot water rebates or incentives may be available in some areas, but they can change and may depend on product eligibility, installer eligibility, property details and program rules.

Before choosing Envirosun based on rebates, check:

Current rebate rules
Product eligibility
Installer requirements
Property eligibility
Customer eligibility
Whether the offer is still active
Whether the advertised price includes or excludes rebates
Whether the rebate applies to supply-only purchases

Do not choose a heat pump based only on rebate assumptions. A rebate does not make an unsuitable location suitable.

Common Mistakes When Buying an Envirosun Heat Pump

Choosing by Rebate First

Rebates can change and may not apply to every product, property, installer or purchase type. Suitability should come first.

Choosing the Smallest Tank

A smaller tank may cost less upfront but may not suit families or homes with higher peak use.

Ignoring Airflow

Heat pumps need suitable air movement. Poor airflow can make the location unsuitable.

Forgetting Noise Placement

Noise should be checked before ordering, especially for townhouses, units and homes with close neighbours.

Forgetting Condensate Drainage

Condensate needs somewhere practical to go.

Assuming Any Electric Tank Can Be Replaced With a Heat Pump

Heat pump suitability depends on location, airflow, electrical requirements and drainage.

Comparing Supply-Only Price to Installed Cost

Supply-only pricing is not the same as full installed cost.

Forgetting Valves and Fittings

The unit may not be the full order. Accessories may also be required.
