Envirosun & Enviroheat Hot Water Systems
Envirosun hot water systems cover heat pump, solar and instant gas
technologies, giving homeowners several different ways to replace or
upgrade their existing hot water. The Enviroheat name is also closely
associated with this range: earlier Envirosun heat pump systems were
marketed under the Enviroheat name, while JR's current range is primarily
presented under Envirosun.
For customers who still search for an Enviroheat hot water system or
Enviroheat heat pump, the important point is that these products sit
within the same broader Envirosun hot water family. JR Gas & Water
therefore keeps both Envirosun and Enviroheat terminology together so
customers can identify older systems and compare their current
replacements.

systems across Brisbane, the Gold Coast and eligible South East
Queensland service areas.

Envirosun vs Enviroheat: Are They the Same Brand?
Envirosun and Enviroheat are closely related names within the same broader
hot water product family. Enviroheat was used as the name for earlier heat
pump systems, while Envirosun has become the more prominent name across the
current range sold by JR Gas & Water.
That means a homeowner searching for an Enviroheat heat pump may now find
current equivalent or replacement products listed as Envirosun. JR keeps
both names throughout this page because older Enviroheat systems remain
installed in Australian homes and customers commonly search using either
brand name.
For replacement purposes, the important information is the exact model,
capacity, electrical connection and installation requirements rather than
whether the older system badge says Enviroheat or the newer product is
marketed as Envirosun.
Envirosun & Enviroheat Heat Pump Hot Water Systems
Heat pump hot water is a major part of the Envirosun and Enviroheat range.
Instead of heating water entirely with a conventional electric resistance
element, a heat pump transfers heat from the surrounding air into the stored
water.
This makes Envirosun and Enviroheat heat pumps particularly relevant to
households replacing traditional electric storage systems and wanting to
reduce purchased electricity used for water heating.
Envirosun M9 200L
The Envirosun M9 200L sits at the smaller end of JR's current M9 range
and can suit lower-demand households that want heat pump efficiency
without moving to a large-capacity tank.
From
Envirosun 250L / Enviroheat 250L
The 250L-class system provides a useful middle-ground heat pump option
and is particularly relevant to customers replacing an older Enviroheat
system or wanting a value-focused Envirosun heat pump for everyday
family use.
From
Envirosun M9 330L
The Envirosun M9 330L provides greater stored capacity for larger
households or homes with higher daily hot water demand while retaining
the efficiency advantages of heat pump technology.
From
Envirosun Solar Hot Water Systems
Solar hot water remains one of Envirosun's strongest product categories.
JR's current range includes both active split systems, where the storage tank
remains at ground level, and thermosiphon-style systems that place the tank
and collectors on the roof.
Current Envirosun solar options include AS split systems and TS / TSP+
roof-mounted systems in several capacities and collector configurations.
The best choice depends on household demand, roof space, roof structure,
solar exposure and the way the existing system is installed.
Envirosun AS Split Solar
Envirosun AS systems keep the storage cylinder at ground level while
roof-mounted collectors gather solar energy. This can suit homes where
reducing roof weight or keeping the tank accessible at ground level is
preferred.
Envirosun TS / TSP+ Solar
Thermosiphon-style Envirosun solar systems locate the storage tank with
the collectors on the roof. They provide a more traditional roof-mounted
solar hot water configuration for suitable properties.
Envirosun Instant Gas Hot Water Systems
Envirosun also offers continuous-flow gas water heaters for homes that want
compact wall-mounted hot water without a storage cylinder. Current JR
Envirosun gas products include 20L and 26L-class systems, subject to current
availability.
Instant gas sizing is based on required flow rather than tank capacity.
Household demand, number of simultaneous outlets, gas supply and required
temperature rise all need to be considered before selecting a model.
Replacing instant gas?
Do not automatically assume the same litre-per-minute rating is always the
correct replacement. Changes in household demand and the existing gas supply
should be considered before selecting the new Envirosun unit.
What Size Envirosun or Enviroheat Hot Water System Do I Need?
The correct size depends first on which Envirosun technology you are
considering. Heat pumps and solar systems use stored-water capacity, while
instant gas systems are selected primarily by continuous flow rate.
For Envirosun and Enviroheat heat pumps, JR's household sizing approach uses
approximately 40 litres per person per day for light usage, 50 litres for
average usage and 65 litres for higher usage before matching the result to a
practical system capacity.
Solar sizing also needs to consider collector configuration and available
solar contribution, while instant gas sizing is driven by simultaneous flow
requirements rather than storage volume.
Replacing an older Enviroheat?
Do not automatically replace it with the same storage capacity simply
because that is what is installed now. Household size and hot water use may
have changed since the original system was selected.
Which Envirosun Hot Water System Should I Choose?
Choose Envirosun / Enviroheat Heat Pump If…
You want to move away from conventional electric storage, reduce
electricity consumption and prefer a ground-level installation without
roof-mounted solar collectors.
Choose Envirosun Solar If…
Your property has suitable roof space and solar exposure and you want
direct solar energy to provide a significant portion of household water
heating.
Choose Envirosun Instant Gas If…
The home already has a suitable gas supply and you want compact,
continuous-flow hot water without maintaining a large stored volume.
Replacing an Older Envirosun or Enviroheat Hot Water System
Older Enviroheat heat pumps remain installed in many homes, so homeowners
may search for Enviroheat even though current replacement products are
increasingly presented under the Envirosun name.
Replacing an older Enviroheat does not necessarily mean selecting the exact
same model or capacity. Current Envirosun heat pumps can provide an updated
replacement pathway, but electrical connection, system dimensions,
drainage, clearances and household sizing should all be checked first.
Likewise, an older Envirosun solar system can be replaced with another solar
system or compared with heat pump hot water if the homeowner wants to avoid
future roof work. Envirosun instant gas can also be compared where the
property has suitable gas infrastructure.
Envirosun & Enviroheat Installation Brisbane & Gold Coast
JR Gas & Water supplies and installs eligible Envirosun and Enviroheat hot
water systems throughout Brisbane, the Gold Coast and eligible South East
Queensland service areas.
Installation requirements differ substantially between the three major
Envirosun technologies. Heat pumps need appropriate electrical supply,
drainage, airflow and clearances. Solar systems require suitable roof access,
collector positioning and roof installation. Instant gas systems need
appropriate gas capacity, pipe sizing, water connections and mounting
conditions.
Where the correct Envirosun or Enviroheat replacement cannot be confidently
determined online, JR can inspect the property or provide a written quote
before the final system is selected.

Is Enviroheat now Envirosun?
Enviroheat was used as the name for earlier heat pump systems within
the broader Envirosun product family. Current JR products are primarily
presented under the Envirosun name, although many customers still
search for Enviroheat when replacing an older heat pump.
For that reason JR groups Envirosun and Enviroheat together when
helping customers identify older units and compare current
replacements.
Is Enviroheat the same as Envirosun?
The names are closely related. Enviroheat was associated specifically
with the earlier heat pump range, while Envirosun is the broader brand
covering current heat pump, solar and gas hot water products.
Can I replace an old Enviroheat with an Envirosun heat pump?
In many cases, yes. Current Envirosun heat pumps can provide a
replacement pathway for older Enviroheat systems, but the correct
model should be selected based on household demand, electrical
connection, physical dimensions, drainage and installation
clearances.
What sizes do Envirosun heat pumps come in?
JR's current Envirosun and Enviroheat range includes heat pumps across
smaller, mid-size and larger household capacities, including current
200L-class, 250L-class and 330L-class options subject to availability.
Is the Envirosun M9 200L or M9 330L better?
Neither size is automatically better. The M9 200L can suit lower hot
water demand, while the M9 330L provides substantially more stored
capacity for larger households or higher daily use. Correct sizing is
more important than simply choosing the larger model.
Is an Envirosun heat pump cheaper to run than electric storage?
Heat pumps are designed to use less purchased electricity for water
heating than conventional resistance electric storage because they
transfer heat from the surrounding air. Actual running cost depends on
household demand, electricity tariff, system settings, climate and any
solar PV available at the property.
Does Envirosun make solar hot water systems?
Yes. Solar hot water is a major part of the Envirosun range, including
split systems with the tank at ground level and thermosiphon-style
systems with the tank and collectors mounted on the roof.
Does Envirosun make instant gas hot water systems?
Yes. Envirosun has continuous-flow gas hot water options, including
20L and 26L-class systems within JR's broader instant gas range,
subject to current availability.
Can I replace Envirosun solar with an Envirosun heat pump?
Yes, where the property is suitable. Moving from solar hot water to a
heat pump removes the roof-mounted collector requirement, but the new
heat pump installation needs suitable electrical supply, drainage,
airflow and ground-level space.
Can JR install Envirosun and Enviroheat in Brisbane?
Yes. JR Gas & Water supplies and installs eligible Envirosun and
Enviroheat heat pump, solar and instant gas hot water systems
throughout its Brisbane service area.
Can JR install Envirosun and Enviroheat on the Gold Coast?
Yes. Eligible Envirosun and Enviroheat systems can be supplied and
installed throughout JR Gas & Water's Gold Coast service area, subject
to the selected technology and installation requirements.
Should I repair or replace my old Envirosun or Enviroheat?
That depends on the age of the system, the fault, likely repair cost
and whether the existing technology and capacity still suit the home.
A repairable component fault is different from an ageing tank,
refrigeration failure or deteriorated solar system requiring major
work.
JR's
Hot Water Repairs & Servicing
section provides the available service pathways.
Can I get a quote before choosing an Envirosun system?
Yes. If you are unsure whether heat pump, solar or instant gas is the
best Envirosun replacement for your property, you can
request an onsite or written quote
before choosing the system.
