How Solar Hot Water Systems Work
A solar hot water system uses energy from the sun to heat your water, significantly reducing electricity or gas consumption. Most setups include:
- Solar collectors (usually roof-mounted panels or evacuated tubes)
- A storage tank (located on the roof or ground, depending on the system)
- A booster (gas or electric) for overcast days or periods of high demand
There are two main types of systems:
- Thermosiphon systems – the tank and collectors are on the roof. Water flows naturally between the collectors and tank.
- Split systems – collectors are on the roof, and the tank is located on the ground. A small pump moves the water.
Each system type has pros and cons depending on your roof space, access, budget, and preferred look.
Why Adelaide Is Ideal for Solar Hot Water
South Australia’s climate makes it one of the best places in Australia for solar hot water. With an average of over 2,500 hours of sunshine per year, most households can expect to get 60–90% of their annual hot water needs from the sun.
That said, performance depends on correct system selection and quality installation. Things like collector orientation, shading, plumbing distances, and even local water quality (like in the Adelaide Hills) can affect performance. That’s why we always carry out an on-site assessment before installation.
What’s Involved in Installing a Solar Hot Water System?
Installing a solar hot water system isn’t just a simple tank swap. It requires careful planning and attention to structural, plumbing, and electrical details. Our team handles:
Safe roof access and panel mounting
Structural assessment (especially for thermosiphon tanks)
Proper alignment and pitch for collector performance
Plumbing adjustments and tempering valve compliance
Connection of booster (gas or electric)
Final testing, commissioning, and handover
We’ll also coordinate with your electrician or arrange one if needed. All systems are installed to meet South Australian and national plumbing standards.
Replacing an Existing System
If you’re upgrading from an electric or gas system, we’ll safely remove the old unit and recommend the best solar setup for your property. We’ll check:
- Whether your roof is suitable for collectors
- If you need a roof-mounted or ground-mounted tank
- The plumbing layout and booster requirements
We also help homeowners access any available rebates or incentives.

How Does Solar Compare to Other Hot Water Systems?
Solar + Booster
Solar hot water systems with a gas or electric booster have the lowest running costs over time, since much of your water heating is powered by the sun. While the upfront cost is higher than other systems, they’re ideal for long-term energy savings and reducing reliance on the grid.
Electric Storage
Electric storage systems are typically the most affordable to install but can come with moderate to high running costs, especially if used during peak electricity hours. They’re a straightforward option that suits smaller households or properties where solar isn’t practical.
Gas Continuous Flow
Gas continuous flow systems offer reliable hot water on demand, with mid-range upfront costs and moderate running expenses. They’re a popular choice in areas with access to mains gas and for households that value consistent hot water without the need for a storage tank.
Heat Pump
Heat pump systems use ambient air to heat water, making them an energy-efficient option with lower running costs compared to traditional electric systems. Installation costs are typically mid to high range. They work well in Adelaide’s climate and are often chosen when solar isn’t suitable.
Frequently Asked Questions – Solar Hot Water Installation in Adelaide
How does a solar hot water system work?
Solar hot water systems use roof-mounted solar collectors to absorb the sun’s energy, which heats water stored in an insulated tank. Some systems include a booster (electric or gas) to ensure hot water is always available, even on cloudy days or during winter.
Is my roof suitable for solar hot water panels?
Most Adelaide homes are suitable, but roof orientation and pitch can impact performance. Ideally, your roof should face north and receive good sunlight throughout the day. We’ll assess your roof during our site visit to make sure a solar setup is viable and efficient for your property.
What size solar hot water system do I need?
That depends on your household size and hot water usage. For example, a 300L tank with 2–3 solar collectors suits most 3–5 person households. We’ll recommend a system based on your daily habits, budget, and available roof space.
Can I replace my existing gas or electric system with a solar one?
Yes, in most cases we can upgrade you from gas or electric to solar. Depending on your current setup, it may require extra plumbing or electrical work, but we’ll guide you through every step and provide a clear quote upfront.
Will I still have hot water on cloudy days or in winter?
Yes. Most solar hot water systems in Adelaide come with a booster, either gas or electric, that kicks in when solar input isn’t enough. This ensures you’ll always have hot water, regardless of the weather.
How long does solar hot water installation take?
Standard installations usually take one full day. More complex upgrades (e.g. switching from electric to solar with roof work) may take longer. We’ll give you a time estimate during your quote.
How much can I save with solar hot water?
Savings vary depending on your usage and the type of system you install, but many Adelaide households see significant reductions in their electricity or gas bills, often up to 60–80% of their water heating costs.
Are there rebates for solar hot water systems in South Australia?
Yes, there are often federal STC (Small-scale Technology Certificate) incentives available, which we apply at the time of sale to reduce your upfront cost. We’ll let you know what rebates apply to your chosen system.
What kind of maintenance is required?
Solar hot water systems are generally low-maintenance but should be checked every few years to ensure optimal performance. We offer servicing and support, and we can set a reminder for your next check-up if you’d like.
