Hot water accounts for a significant portion of household electricity usage, particularly in homes running traditional electric storage systems.
With Brisbane receiving strong sunshine throughout the year, solar hot water is one of the most effective ways to reduce long-term energy costs.
Benefits of solar hot water include:
For many Brisbane households, switching from electric storage hot water to solar can deliver substantial long-term savings.

The right solar hot water system depends on your roof layout, household size and hot water usage. We’ll recommend a system that suits your property and budget while delivering reliable long-term performance.



Solar hot water is a strong option for many Brisbane households, particularly homes currently using electric storage hot water systems.
A solar hot water system is likely a good fit if you:
A smaller household or heavily shaded roof may require a different approach such as a heat pump system.
We can assess your property and explain the most suitable option during your consultation.
Thermosiphon systems position the storage tank directly above the collectors on the roof.
These systems rely on natural heat circulation without the need for a pump, making them simpler and more cost-effective.
Split systems position the storage tank at ground level while a pump circulates water between the collectors and the tank.
These systems are commonly chosen for:
Solar hot water systems include either electric or gas boosting to ensure reliable hot water during extended cloudy periods or high demand.
Electric boosters are the most common option for Brisbane homes, while gas boosters may suit homes already connected to natural gas.
Eligible solar hot water systems qualify for Small-scale Technology Certificates under the federal Small-scale Renewable Energy Scheme.
These certificates operate as an upfront discount applied directly to your installation cost.
The rebate amount depends on:
Queensland properties benefit from strong solar zone ratings which can improve STC values.
As a registered installer, we calculate and apply the rebate during the quoting process so you know your total installation cost upfront.

Yes. Eligible systems qualify for STC rebates which are applied upfront to the installation cost.
Flat plate systems are more affordable and well suited to Brisbane’s climate. Evacuated tube systems can provide improved performance in cooler conditions and higher heat output per square metre.
Thermosiphon systems position the tank on the roof while split systems position the tank at ground level with pumped circulation.
With proper maintenance, many systems operate reliably for 15 to 20 years.
Yes. We diagnose and repair a wide range of solar hot water faults.
Solar hot water systems are generally low maintenance, though periodic servicing and sacrificial anode replacement are recommended.
