The iHeat 300L Single Panel Solar Hot Water System is a roof-mounted electric boosted solar hot water system designed for smaller households, compact roof spaces and homes where a single collector system is the right fit.
It combines a 300L roof-mounted storage tank with a large single flat plate solar collector and electric boost backup. This gives homeowners solar-assisted hot water during suitable conditions, with electric boosting available when stored water temperature drops below the set point.
For homes with good roof exposure, moderate hot water demand and limited ground-level space, the iHeat 300L single panel system is a practical option for replacing an older roof-mounted solar hot water system or upgrading from a standard electric storage unit.
JR Gas & Water supplies and installs solar hot water systems across Brisbane, the Gold Coast, Logan, Ipswich, Redlands, Scenic Rim, Moreton Bay and surrounding South East Queensland areas.
The iHeat 300L single panel system is designed for homeowners who want solar hot water in a compact roof-mounted format.
Key benefits include:
300L roof-mounted storage tank
single high-performance flat plate solar collector
electric boost backup
close-coupled roof-mounted design
thermosiphon circulation
no electric circulation pump required
open-loop solar hot water design
all-copper collector with black chrome selective surface
suitable for smaller households
ideal for limited roof space
practical replacement for existing roof-mounted solar systems
WaterMark approved system range
designed for Australian conditions
For the right home, this system provides a straightforward solar hot water setup without the extra roof space required for a twin panel system.
The iHeat 300L single panel solar hot water system is well suited to:
1–3 person households
couples and smaller families
homes with moderate hot water use
properties with good solar exposure
homes with limited roof space
single-storey homes with suitable roof access
replacements of older roof-mounted solar hot water systems
homeowners wanting electric boost backup
homes where a twin panel system is not required
buyers wanting a simple solar hot water setup
It is generally not the best option for larger families, heavy shower use, multiple bathrooms running at the same time, or homes with poor roof orientation and heavy shading.
The iHeat 300L single panel system is best known for combining a full 300L storage tank with a compact single collector layout.
That matters because not every household needs a twin panel solar hot water system. A single panel setup is usually the better fit when:
hot water demand is light to moderate
roof space is tight
the roof has strong solar exposure
a compact system is preferred
the household has fewer occupants
the existing system is already roof-mounted
the owner wants solar hot water with electric boost backup
This makes the iHeat 300L single panel system a practical middle ground: more storage than a smaller system, but less roof collector area than a twin panel solar setup.
The iHeat 300L single panel system uses a traditional close-coupled roof-mounted solar hot water design. The storage tank and solar collector are installed together on the roof, which keeps the main system components off the ground and makes good use of available roof space.
The system uses natural thermosiphon circulation. As water heats in the collector, it rises into the storage tank without needing a separate circulation pump. This keeps the system simple and low maintenance compared with pump-driven split solar systems.
Roof suitability still matters. The roof structure, pitch, orientation, shading, access and existing pipework all need to be checked before installation.
The single collector setup is designed for smaller households, tight roof spaces and homes with strong solar contribution.
The confirmed single collector specification is:
| Specification | iHeat Single Flat Plate Collector |
|---|---|
| Collector model | CSG25 x 1 |
| Width | 1247mm |
| Length | 2000mm |
| Depth | 95mm |
| Weight | 46kg |
| Aperture area | 2.5m² |
The single panel design is especially useful where the roof has limited usable space or where a twin panel system would be unnecessary for the home’s hot water demand.
The iHeat 300L single panel system includes electric boost backup using an in-tank electric element.
The electric booster helps maintain hot water availability when solar input is not enough, such as during cloudy weather, higher-than-usual hot water use, winter conditions or periods of lower solar contribution.
This makes the system more practical for everyday use because the home is not relying on solar input alone.

Specs should always be checked against the exact current unit supplied, site conditions and manufacturer documentation at the time of installation.
The iHeat 300L single panel system is usually the better fit when:
the home has 1–3 occupants
hot water use is light to moderate
roof space is limited
the home has strong solar exposure
a lower collector footprint is preferred
the existing system is a single panel roof-mounted unit
the household does not need high solar recovery
A twin panel solar hot water system is usually the better fit when:
the household has higher hot water demand
more people shower each day
there are multiple bathrooms
evening hot water use is heavy
the roof has enough suitable space
stronger solar recovery is required
The best choice depends on household size, shower habits, roof orientation, available roof space and how much hot water the home actually uses.
A standard electric storage hot water system is usually simpler and cheaper upfront, but it relies on electric heating rather than solar contribution.
The iHeat 300L single panel solar hot water system is the better fit when you want:
solar-assisted hot water
electric boost backup
a roof-mounted system
lower reliance on standard electric water heating
a replacement for an older roof-mounted solar unit
a compact collector layout
a system suited to smaller households
A standard electric hot water system may still suit homes where roof mounting is not suitable, where roof access is difficult, or where the lowest upfront replacement cost is the main priority.
A heat pump hot water system is usually installed at ground level and uses heat from the surrounding air to heat the stored water. It can be a strong option for homes where roof-mounted solar is not suitable.
The iHeat 300L single panel solar system is better when:
the home already has a roof-mounted solar system
the roof has good solar exposure
ground-level space is limited
the homeowner prefers roof-mounted solar hot water
a like-for-like solar replacement is practical
A heat pump may be better when:
roof access is difficult
the roof structure is unsuitable
shading affects solar performance
the customer wants a ground-mounted hot water system
the home has solar PV and wants daytime electric hot water heating
Both options can work well in South East Queensland. The right choice depends on the property layout, budget, roof suitability and household usage.
A roof-mounted solar hot water system needs proper site assessment before installation.
Key installation factors include:
roof structure and load capacity
roof pitch
roof orientation
shading from trees or nearby buildings
safe roof access
crane or lifting access where required
hot and cold pipework layout
existing system location
electrical boost connection
tempering valve requirements
pressure control valves
drainage and relief valve discharge
water quality
local plumbing and electrical compliance
Because the tank and collector sit on the roof, the roof must be suitable for the system. The system also needs to be positioned to support safe access, good solar exposure and practical pipework routes.
JR Gas & Water provides professional solar hot water installation across Brisbane, the Gold Coast and South East Queensland.
A standard installation may include removing the old hot water system where required, lifting and positioning the new roof-mounted solar system, connecting compliant plumbing, arranging licensed electrical work for the boost connection where needed, fitting required valves, testing operation and commissioning the system.
Some installations may need extra work depending on roof access, roof condition, system weight, electrical requirements, pipework changes, valve upgrades, lifting access and whether the existing system is being replaced like-for-like.
Same-day installation may be available on suitable iHeat 300L single panel solar replacements, depending on stock, roof access, weather, lifting requirements, electrical readiness and the existing system setup.
Straightforward like-for-like replacements are usually the fastest. More involved jobs may take longer if roof access is difficult, the system location needs to change, electrical work is required, or the old unit is difficult to remove safely.
The goal is always to install the system properly, not rush a roof-mounted solar job that needs safe lifting, compliant plumbing and correct commissioning.
Choosing the right installer matters with roof-mounted solar hot water because the final result depends on more than just tank size.
