Gas Hot Water Systems (Instant / Continuous Flow)
Gas systems are extremely popular across Adelaide, especially where natural gas is available.
Instant (continuous flow) systems heat water only when you turn the tap on, meaning you don’t store and reheat a tank all day.
Benefits
✔ Lower upfront cost than heat pumps or solar
✔ Fast, endless hot water
✔ Very reliable
✔ Compact wall-mounted units
✔ Low running costs with natural gas
They’re also perfect for simple changeovers if you’re replacing an older gas unit.
Best for
Families wanting affordable installation + reliable performance.
Solar Hot Water Systems
Solar hot water uses roof panels to capture the sun’s energy and heat your water naturally.
These systems use either gas or electric boosting when sunlight is limited.
Benefits
✔ Very low running costs
✔ Environmentally friendly
✔ Government rebates available
✔ Significant energy savings
However, performance depends on sunlight and the upfront cost is typically higher.
Best for
Homes with good sun exposure and owners focused on environmental benefits.
Electric Hot Water Systems
Electric storage systems are often the lowest purchase price, but they generally have the highest ongoing running costs due to electricity prices.
They can still be suitable in some situations.
Benefits
✔ Cheapest upfront option
✔ Simple installation
✔ Good for tight budgets
✔ Works well with off-peak tariffs
Downsides
✖ Higher electricity bills
✖ Less efficient than other options
Best for
Budget replacements or properties without gas access.
So… Which System Is Best?
Here’s a simple way to decide:
-
Want lowest long-term bills → Heat Pump
-
Want affordable + reliable → Gas
-
Want eco-friendly solution → Solar
-
Need cheapest upfront option → Electric
Every home is different, which is why professional advice matters.
